How can I backup and restore Cyanogenmod 12.1 rom installed on my Samsung Galaxy 2 i9100? Cyanogenmod(12.1)'s recovery has no backup or restore option. As I read in the answer of a previous post, CyanogenMod recovery is basic, so we should flash another recovery. The easiest way would be to use rashr, Fashify or GooManager to install CWM or TWRP. Unfortunately, these solutions don't work on my i9100.

An other answer in the same post says : "Especially for Galaxy S2. I stuck with Cyanogen Recovery for a couple of days. Neither Rashr nor Flashify worked for me. In the end, reflashing a TWRP kernel (Apollo 9 light) with Flash Gordon did the trick."

My questions are where do I find this TWRP kernel and how do I install it ?

I found a link to a signed stock kernel providing TWRP v2.8.7.0 on xda Forum : [ROM][I9100][5.1.1][OFFICIAL] CyanogenMod 12.1 Nightly Builds

It can be flashed with the Cynogen Recovery.

How to change search engine language? I'm a native Hungarian speaker, a few months ago I moved to Germany, and I have a problem with the Google search, I installed the Google chrome on my android device but the default search engine is German(google.de), it's so annoying when I would like to get English results, but instead of that I'm getting Germany results. How can I change that?

Set yor language by clicking on 'Einstellungen' or navigate directly to the english localized version: http://www.google.com/preferences?hl=en to set it there (you can switch the 'hl=en' for english to hl=hu for hungarian or any other you want in the link).

Setting your start page is not what you want: This will not affect searches from the widget or from the omnibox (the auto completion, aka instant search).

Edit:
Seems like the keyboard language sets the default... switched from en to german and back.


ro.adb.secure=0 device still shows as unauthorized over adb Windows 10 I recently purchased a tablet that is a cheap allwinner a33 based Chinese product. I wanted to connect to it over adb but the RSA key popup would not come up.

The build.prop shows the ro.adb.secure=0 which should mean that the device requires no rsa authentication but my Windows 10 machine still shows the device as unauthorized.

How do I get the device authorized so I can use adb?

I have no root access and would need adb to root.

I don't think ro.adb.secure is the reason why your phones shows up as unauthorized.

ro.adb.secure is a switch to allow adb to launch at boot (or not). relevant discussion.

Your problem sounds more like a local problem with your adb setup on your laptop. You should try the following steps:

download/install correct adb drivers for your linux/windows machine, which are released for this specific chipset (allwinner a33), possibly you won't find much, but something that is compatible hopefully
try lsusb (linux) to find the USB vendor/product ID for the tablet and search for compatible adb drivers
having the vendor and product ID you should be able to understand whether the USB mode for adb is actually enabled on the phone, i.e. if the phone runs USB with mtp,adb / ptp,adb or with just ptp etc.

example with a Moto G4 Play (msm8916):

shell@harpia:/ $ getprop sys.usb.config
mtp,adb

pi@pi:~ $ lsusb
Bus 001 Device 007: ID 22b8:2e76 Motorola PCS
................
shell@harpia:/ $ getprop sys.usb.config
ptp,adb

pi@pi:~ $ lsusb
Bus 001 Device 009: ID 22b8:2e84 Motorola PCS

depending on the USB mode selected on the android phone, the USB product ID is different.

All that is closely related to udev rules (link to relevant discussion), although setting up or manipulating udev rules never solved my problems (and my Raspbian 9 doesn't even have the file /etc/udev/rules.d/51-android.rules).


How to select default application How can I change the default application for a given file type or protocol?
For example, I have multiple browsers on my smartphone and have selected "Internet" (the default browser) to be "the default browser" because it kept asking on every link.

How can I change that to ask me each time or at least select a different option?

Thank you.

Go to:

Settings -> Applications -> Manage applications -> All -> Web [or Internet]

Hit "Clear Defaults" and that will change it to again ask every time.


How do I update all my apps with the new Google Play Store? I want to update my apps, but I can't find the option in the new play store. How can I do this?

On all my devices, if there are more than one app to be updated, I can see the Update <x> button above the apps list, in the header bar with the "Updates" text. This will update all apps that don't require manual updates.


Practical longevity of current Android phones Before continuing to read, please understand that I do not have a smartphone and have never had one. Thus my experience with such devices is minimal.

I am thinking about getting an Android smartphone, but I strongly prefer something that lasts (please don't debate why).  How long do current smartphones stay practically usable?  How long do they last physically, and how long does the software stay reasonably usable?

I do have an iPad 2 (release year: 2011), which at this point is barely usable.  It is in good condition but the (irreversible) OS updates made it slow and many current apps are also so slow as to seriously affect usability.  It used to be the same with computers many years ago, but it isn't so anymore: a 4-5 year old laptop computer holds up perfectly well today, and I see no need to upgrade.  What about current mobile devices?

I am not willing to get a smartphone unless it is likely that it will stay usable for at least 4-5 years.  I'd rather stay with my 6 year old Nokia.  I am not in a position to get a carrier-locked phone, so a getting a quality device would be a significant expense.

To sum up: I am not sure that progress in mobile device performance has already slowed enough to make longevity a reasonable expectation, hence my question.

I second what @DeathMaskSalesman says in the comment - it largely depends on how you use your device and whether you load custom ROMs on it.

Bottom line is, unless you use the phone lightly, nothing can hold up to 5 years nowadays, and even then the battery will wear out. My 3-year-old Nexus 4, when retired at its 2.5 year of service, has its battery down to 1500mAh from the designed 2100mAh. This is increasingly serious a problem since recent smartphones tend to have non-replaceable batteries.


How do I tether over USB in MacOSX? How do I tether over USB in MacOSX?

I plug the phone in, pick up:

  USB tethering

  Share phone's mobile network with PC

which causes the computer to discover a new network interface, but it doesn't just work and the configuration looks like this:

Which telephone number, account name and password is it asking for? I've never got those details from the ISP. I did ask the ISP and the details they gave me made no sense and didn't work.

I'm running the stock Android 2.2 on an HTC Desire, the carrier is Swisscom in Switzerland. I've been told by someone that has the same phone, that plugging it in Windows and doing the same just works without asking for any number or password.

According to this thread, you need to use software like PdaNet to get it to work.


Remove the white background on app drawer on Android 5.1 Is there a way we can remove the white background that shows up forever behind the icons on Android. I read somewhere that Android 6 Developer options may provide that. If someone figured it out on Android 5, please advise.

This is very much possible, but you will require a custom launcher. For the sake of this, we'll use Nova Launcher.

Install Nova Launcher and set it as the default when going back to your Home screen.

Go to the "App & Widget Drawers" screen in Nova settings and scroll down to find the options shown in image. Make sure the switch for "Card background" is set to off.


Can I use an English locale setting on a Polish EEE Pad Transformer? I live in Poland, but I am primarily an English speaker and I cannot speak any Polish. I want to buy the Asus Transformer tablet from a local online store over here in Poland. Will the interface of the tablet will be in English or Polish? If it is in Polish, can I simply change to English by changing the settings or do I have to install any extra software packages or do something out of the ordinary that a normal tablet user wouldn't usually do?

You can change the language within settings -> Language & input.  There are options for English (Canada, United Kingdom, and United States) and Polish (Polski) as well as a variety of other languages.  If it's in Polish, tap the bottom right of the tablet (the clock area), tap the top box (where the time is), tap the bottom option (Ustawienia - Settings), tap the icon that has an A in it (Jezyk i wprowadzanie danych - Language and input) and tap the top option on the right (Wybierz jezyk - Select language).  From there, you can scroll to the English option you want and tap it.

CWM only boots right after flashing, won't boot afterwards I have a rooted GSM Galaxy Nexus running CM 12.1.

Trying to boot into recovery gets stuck on the Google logo. The logo will appear while starting to boot, then the screen will briefly flash black, and then stay stuck indefinitely on the Google logo. Holding the power button powers the device down just fine.

However, if I re-flash CWM, it will boot just fine into recovery. Once. The next time I try, it will get stuck again.

Has anyone else experienced this? Is this a known issue with a possible solution?

If I had to just guess from the discribed simptoms I'd say it's the kernal or hang-time during normal boot of loading the SD card.

The state you're discribing is known as a "soft brick" and "boot loop" among seasoned Android SuperUsers; try the quoted terms along with your device's name in a google search to find other users of your device model that have solved or worked around these issues. There are many forums dedicated to helping with spicific devices but I always go back to XDA-developers and thier forum's members to truble shoot my rooted Android devices. For many devices there's an online resource for flashing ROMs, Kernals and others that goes by the name of C.A.S.U.A.L. a perpious built scripting tool written by a developer I've watched for many years (in a totaly non creepy way) for hacking nearly every device I've owned. The author also provides tools such as jOden which easiy flashes Samsung devices with your PC's browser.

Additinal hint on searching with Google

Search a site site:somewebsite.domain
Search similar sites similar:somewebsite.domain

The above can be added to the end of your search quaries to nerrow down the results considerably.

Here's one link I pulled from using the above tricks mixed with your device's specs;
http://forum.xda-developers.com/galaxy-nexus/development/gnex-toolkit-v11-1-0-drivers-backup-t1392310

You've stated that you can get back into CWM, this means you're not the owner of a "brick", so long as your device can be booted into either "Download Mode" or the "Recovery" screens you're device can be salvaged.

To re-flash your device with a PC you'll need to be in "Download Mode" and flash with a PC via USB, however, before trying these options you should first attempt to re-boot into "Custom Recovery" and restore from a known working backup. Often these bootloops can happen after messing with a "build.prop" setting or if you have moved an app over to SD that wasn't designed for it. The SD card takes a bit of time to load so if you've soft-linked a system asset from it, the asset could be loading during CWM booting process (ie loading the SD card to look for backups) and thus able to be loaded during the rest of the boot but otherwise called before loading the SD card.

** Download Mode is a differant button combo than CWM **

Best bet to keep from losing anything is make a backup now! or the next time you can boot into CWM. Even your non-working setup is usefull if you need to recover a text message or debug the differaces between working and non-working setups. Also it is really easy to do something dumb {I've been close} when frustrated, so give a gift to your future self, on the off chance that it is needed.

Then backup your SD card compleatly to another drive. Then;

reformat the SD card with Android's settings menu
re-download CM12 & copy back only needed data from the backup of SD card back to the SD card

reboot into CWM

flush the cache
flush the delvak cache
whipe userdata
then try re-flashing CM12

These are the steps I follow for the many Android devices I work with and similar steps are preformed for the even older devices. Ocasionally I will have to flash back to stock and re-root a device but this is rare; more often than not it is a bad kernal or bad download of a ROM that does this to my devices.

Oh and bootloops that don't let you get back into CWM without a cold start or PC flash is usually from TWRP to CWM backup/restor or flashing from one over the other in properly; similarly this sometimes happen when moving from stock to Super User; look up BML vs MTD for more info on that. But this is why most root methods have what is usually called "clean"-keral to flash just before going to CM or why when using Oden you have to un-check 'auto reboot' for certain operations. The stock recovery will attmept to overwrite your newer recovery.

Oh and before I forget here is the link to C.A.S.U.A.L. Google code page

The author has also made some really fantastic YouTube terdown & repair videos and has posted some really interesting articals.


How to mount external SD card at a fixed path in CM13? In Marshmallow (and consequently in CM13), the external SD card is mounted at a path that contains its serial number. I have a bunch of Tasker tasks, the occasional script, and lots and lots of apps configured with a specific path to the external SD card (in my case, /external_sd because that's where it was in CM12).

Is there anything sensible I can do about this change in Marshmallow? Fixing paths everywhere just because I've upgraded to a faster/larger SD card (which has a different serial number) is not going to be fun.

How would I go about making the external SD card available under "/external_sd" on CM13/Marshmallow?

I've found a reasonably easy way to do something close enough: just set the volume serial number to something fixed. This is easy enough for FAT32-formatted SD cards: just use Sysinternals VolumeID:

D:\>vol D:
 Volume in drive D has no label.
 Volume Serial Number is 07F5-432C

D:\>volumeid D: ECAD-ECAD

VolumeID V2.01 - Set disk volume id
Copyright (C) 1997-1999 Mark Russinovich
Sysinternals - www.sysinternals.com

Volume ID for drive D: updated to ecad-ecad

("ecad" for "external card" but there are other possibilities, of course)

Now my external SD card is mounted at /storage/ECAD-ECAD, which is easy to remember for typing in those apps which don't let me pick a path, and more importantly, can stay the same when I upgrade to a faster card, for example (if I repeat this procedure).

The only complication is SD cards larger than 32 GB, which Windows refuses to format into FAT32. The best tool to work around this is Rufus, an open-source tool with a focus on bootable drives, but it can also just format a large FAT32 drive.


Why does the Play Store's download percentage never reach 100%? I've owned two Android phones so far. While both are HTC ones, I've used several customised ROMs on the older one, so the following does not seem to be specific to one maker or installation.

I've noticed that whenever I download an application from Google Play Store, the percentage never reaches 100%. It's usually between 40% and 60% when the progress bar disappears and the status changes to "installing".

I considered the possibility that the system begins to install the package before it's fully downloaded but, besides that being a bad idea, many times the installation takes a much shorter time than the rest of the download would have (assuming constant speed).

It seems that, instead, the percentage reported is wrong, and that the file is in fact fully downloaded while the screen shows 40%. Does that happen to others as well? How is it explained?

This started happening at the same time that Google introduced the concept of "delta" updates.  This means that only the portion of the app that has been modified is sent over, as opposed to the entire app.  However, they never changed how the Play Store app calculates the download percentages - it's still taking app's full size as the base 100%, instead of the size of the delta update being downloaded.  It simply never bothers to check with the download manager (which works correctly, as reflected in the notification tray) for the correct size of the delta.

This is why you are seeing the percentage stop at random times - the difference in sizes of the full app and the delta is what's making the play store think the download is larger than it actually is.  For example, if an app's full size is 10MB, but the update is only 5MB in size, the Play Store will still think it's downloading the full 10MB, and will stop at 50%, when the 5MB download completes.


my phone glaxey s4 had its screen crashed and Ive changed it and now it wont charge My Samsung Galaxy S4 keeps showing the message "Charging paused. Battery temperature is too low", whenever I plug the phone into a charger. I've tried using a different charger and even another battery but the message re-appears and the phone continues to not charge.

How can I resolve this problem?

Reflash the stock rom using odin.
If it didn't work, change the power socket


How can I search the contents of the books I added to my Google books? I want to search the contents of the books I added to my Google Books account.

The Google Books web site offers a search my library option.

But I want to search the contents of the books in my Google Books account from my Android device and from an Android application which is optimized for small screens.

I think your question could be worded better as it seems to ask a couple of questions.

Google books are filed as cryptic alphanumeric IDs, and they seem to be HTML type files it makes it more difficult than with most other book types.

finding books on your device is very easy, use an explorer like File Expert or Astro (both are free, however Astro's search function is better) which contain a search option. You will probably have to use multiple searches depending on how many different types of ebooks you have on your SD card - I know I have epubs, mobi, prcs, pdf, txt and doc files.
If you are looking specifically for just your google books then as long as you have set to store them on the SD card they will be under the following path - Storage Card/Android/Data/com.google.android.apps.books
Searching contents of books within google books - you can't from the library or app itself, unless you are already in the book - in which case press menu and then use search.
However due to the nature of google books you could probably do this much quicker via the website. With other book and file types you could try Astro's search within text - might just pull up what you are looking for as I have had this work on some txt and doc files.

Can I video talk from my Android Motorola Droid to someone else's computer? If so, how?

If you have Android 2.3.4 or higher you are able to video chat with GTalk.

Even better, Google Hangouts allows you to perform one to many video chats.


read-only file system on emulator I need to change /system/etc/hosts file on my emulator, and no matter what I do, I get "read-only file system" error. Does anyone know how to do it?

I tried editing the file manually as su in adb shell, I tried pushing the file in device monitor (in Android studio), also tried adb remount to remount the file system as many online resources suggest.

Thanks!
Konstantin

I tried your answer but it didn't work.
Eventually the following Stack Overflow Answer worked.

1) android-sdk-macosx/tools/emulator -avd <avdname> -writable-system
2) ./adb root
3) ./adb remount
4) ./adb push <local>/hosts /etc/hosts

Android file host can be
/etc/hosts <--- This worked for me
/etc/system/hosts
/system/etc/hosts

Check
1) ./adb shell
2) cat /etc/hosts
3) ping customsite.com


How to reinstall Playstore? Do you have any Idea to reinstall Playstore?

Why are preinstalled apps so small? On Android 7 I have some apps preinstalled. I'm talking about fresh installed apps without user data:

AOSP Keyboard - 152 KB
Browser - 180 KB (org.lineageos.jelly)
E-Mail - 288 KB  (com.android.email)
Calendar - 116 KB (com.android.calendar)

Why are these app so small compared to some small apps I have installed

Unit Converter Ultimate ~ 8MB

Because Android 7 only shows space occupied from /data.

This is my phone [OnePlus 5]. Using the same app AOSP Keyboard as example.

In settings it shows as 260KB, and

# du -sh /data/data/com.android.inputmethod.latin
24K     com.android.inputmethod.latin
# du -sh /system/app/LatinIME
19M     LatinIME

Personal guess: A normal user can't alter how much space an app takes in /system, so Android chooses to directly ignore it.


Can a charger not 100% compliant to the USB specification damage my Andoid phone? I've bought a world adapter which can charge USB devices as well.
According to the packing the usb will be powered with more than the 500mA as per USB specification - 1000mA.

Will charging my HTC Desire with this USB/travel adapter damage my phone?

I know that many main boards don't deliver 500mA per socket esp. when another draining device is attached to the neighboring port.

In most cases your phone will only draw as much power as it needs, and it's OK that the charger can provide more.  However, unless you know that your phone will do this and has other power management safety features, I wouldn't use the charger myself.  I've never had a phone ruined, but I have had batteries ruined by non-official chargers (including one charger that claimed to meet the specifications for my phone).


Is it possible to know if an app has advertisements by analyzing permissions? Or if not, how to see if an app has advertisements or not?

You cannot see that just by checking an app's permissions: those permissions ad modules require for their job are the same the app itself might need for another job. You can, however, look up the app at AppBrain: for each app, that site lists up what ad modules (and other libraries) are used. You find that scrolling down to the "Libraries" section. AppBrain distinguishes between "Development tools" (which also include analytic libraries like Google Analytics or Flurry), "Social libraries" (Facebook & Co), and "Ad network libraries" (Admob & Co).

Libraries used by an app as shown by AppBrain

Clicking on an entry also reveals details on that module/network.


How to root but not root Samsung Galaxy Player 5.0 Recently my family signed up for an offer from Google called Screenwise Select. As a part of the deal we got a smartphone used to connect to our TV and monitor TV shows that we watch. The phone is a Samsung Galaxy Player 5.0. However, evidently the Screenwise app is more than an app; it's taken over the phone. When I turn it on, the "swipe to unlock" appears for a split-second, then it flips over to this app. I can't get out if it. I suspect the system has been somehow modified so that the phone can only be used with the app.

So, my question is - is there a way to "root" but "not root" the phone - that is, to get the system back to normal with the app running like a regular app?

I think the app is in the AppStore so the other option is to factory reset the device and then install the app, but I don't want to do that without confirmation from the Screenwise people.

Any ideas?

You can't do it....don't do it unless you want to get booted from the Screenwise panel and also be billed for the device (currently over $200 retail).

It's running a skin over the top of the device, similar to how Samsung runs their own TouchWiz interface over the top of Android OS. It's not just an app that's running on top (although there is a separate and completely different Screenwise app on the Android Market that is used with this panel, it's not the same thing).


HTC Desire S not listed on HTC support website? I should be getting a HTC Desire S android phone in the next few days. It is listed on the HTC website at http://www.htc.com/uk/product/desires/overview.html, but doesn't appear on the HTC support site at http://www.htc.com/uk/support.aspx.

Does anyone know why this this is, or how I can get to the support page for this phone? I'd like to have a look at the Users Guide before the phone arrives.

Have you tried the manual from the International site?


What Changes Take Place When Installing A Custom Launcher eg Nova To A Rom? If I install a custom launcher eg Nova on Stock Android 4.4.3, what inherently changes ?

Similarly if I were to then install a custom rom eg Paranoid Android, are the benefits gained from installing it then overshadowed or "lost" if I were to then install Nova launcher ?

To clarify wouldn't the experience of Stock Android with Nova and Paranoid Android with Nova be very similar if not identical ?

If you install a alternate launcher, the first thing you'll see is a difference in how the home screen, widgets, (maybe lockscreen if it has support for that), and the app drawer appears and works.

AFAIK that's the only changes you'll see from changing the launcher regardless of what ROM you use.

But one thing's for sure - depending on which ROM you get, the experience will change very little or a lot.


ICS (Android 4.0.3), Samsung Galaxy S2, Exchange Email My phone just updated to ICS (Android version 4.0.3). Before I was able to ACCESS all sub-folders in my microsoft exchange email account, now I can only see my inbox!

How do I fix this?  Does anyone know how to see the sub-folders when using ICS?  I was able to before my phone updated to ICS, now I cannot!

Is it because of my phone? I am using a Samsung Galaxy S2.

I just had the same problem and I found a way of seeing the subfolders on my Galaxy.

On the PC, open your inbox and create a new subfolder (eg foo).

On your phone, open email and open your inbox. in Options, select 'Folders'.
You will see your Inbox with a small green arrow icon. Click the icon (not the Inbox title) and your folder list will expand.

Note that this only worked for me after I had created the extra dummy folder. Before I created the folder, I could see the green icon, but it would not expand the list of subfolders.


Problems with Huawei Phone I have a Huawei Android phone with 512 MB ram and a 1.2 GHz quadcore processor with 4GB internal memory with JellyBean on it. For the past few days no game is running on it. I have tried Riptide GP2, Dead Trigger, World at Arms but to no avail. They install but when I open them they load 20-30% and then it comes back to the menu screen with a wheel rotating.

I thought it was a problem with my ram but I researched that RAM frees itself to run apps. I have 30-40 MB free ram so please tell me what to do as I am really annoyed. I know it has good hardware as its antutu benchmark score is around 14000.

I do not want to root my phone.

I've uninstalled many apps just to make the games work, but it didn't work. I would like to play these games.

As others have mentioned in the comments, 512 MB RAM with 30-40 MB free might be insufficient for running newer, resource-hungry games.  Your version of Android (4.1, according to Huawei g520-5000's specifications) already handles memory quite efficiently by terminating background apps when more RAM is required for games and such.

Your best bet would be contacting the game developers over e-mail and asking for help.  Many will provide some support, just be prepared to know how to extract and send over the phone's logs.  Some, such as Vector Unit (developer of Riptide GP2) even go as far as issue a refund if they can't help you with the problem:

Quote from Riptide GP2's Play Store description:

  • • CUSTOMER SUPPORT • •

Galaxy S won't boot, stuck in recovery mode My galaxy S was working good until about a month ago when it froze and needed to reboot.  Now when it boots, a screen showing a mobile phone and a computer and an exclamation mark in the middle is appearing.  How can I resolve this?

If your phone is stuck in recovery mode, you can try these steps to force it to boot to Android:

Remove the battery, wait a couple of minutes, then put the battery back in.
Turn on phone and see if it still boots into recovery mode.
If it does still boot into recovery mode, hold down "Volume Up" button and then press the Power button.
The recovery menu should appear; using the Volume buttons to move the cursor, select "Reboot system" and press the power button to select it.
If it still boots to Recovery, go into the Recovery menu again and select "Factory Reset/Wipe Data".  Your phone should be reset back to factory defaults and boot properly.

If none of this works, most likely it is a hardware issue and you'll need to get the phone itself looked at by a technician.


Enabling Android as USB host on Galaxy Nexus or Nexus 10 I'm trying to develop applications that talk to USB devices, but nothing works. I installed a USB Host Diagnostics app, and it tells me that there's no OS support for device detection on the Galaxy Nexus or the Nexus 10. I'm running Android 4.2 on both.

I tried the AdbTest sample application, but that doesn't respond when I connect the devices together. I tried updating the files in /system/etc/permissions as discussed here, but that doesn't do anything.

Can anyone get USB device detection to work on these devices? Thanks!

I don't know the specifics about n10, but I found out an issue with my n7. When I bought it I got USB OTG/host working, but now when I tried with 4.2 it does not work anymore!

I found out that it was configured incorrectly. If you check /etc/permissions/tablet_core_hardware.xml you should see line android.hardware.usb.host in there, but after 4.2 upgrade it was not there anymore.

So for me it looks like the only way to get it working is to root the device. :-( I wonder why it has been taken out.


How can I get back access to the media interface drivers? After much waiting and tribulation, I've finally successfully unlocked tethering and installed Paranoid Android on my Nexus 7 3G device.

In the progress, I had to tell Windows to ignore its default MTP drivers and use Google's debugging own to interface with Android, fastboot and the like. As a result, I now can't go back to accessing the device using MTP from inside Windows itself.

I tried uninstalling all the relevant drivers from Device Management, but now Windows prefers Android ADB Interface to whatever I was using before. I've tried to force the setup of MTP drivers from Device Management, Add legacy hardware, Install the hardware that I manually select from a list, Portable Devices, (Standard MTP Device), MTP USB device. This didn't work ("This device cannot start. (Code 10)").

How can I get file transfer back?

Try to identify the location of the driver on the system ie, windows/system32 then uninstall the software and the driver from device manager. Once you have done that return to system32 or where ever its located and delete it. Reboot your system and try installing the old drivers.


Wirelessly sync music folder to microSD card I am looking for a way to sync, wirelessly or over a cloud service, a (music) folder from my computer to the microSD card on my rooted phone.
I've been trying this on Android MM with Titanium Media Sync app but it seems MM restricts the app from writing on the SD-card "Error. Failed to create local folder."
I recall to be able to do so on another phone with CynogenMod...

Probably the feature that TMS is missing is superuser permissiom request. FolderSync as noted in the comments does asks for superuser priviledges and can perform two way syncing!


iplayer app for BBC radio programs on 2.3.5? Are there any iplayer-like apps to listen to recorded BBC radio programs on 2.3.5?

TuneIn Radio has channels for BBC radio, other radio streaming apps probably have them too. TuneIn is a good app, the pro version even lets you record. I am not sure what other features the pro has over the lite version, but I use TuneIn daily.


How do I root Sony Ericsson Xperia Pro (MK16a/i)? I am kind of new to Android and smartphones.

Phone: Sony Ericsson Xperia Pro
Model number: MK16a
Android version: 2.3.4

So far, I have been able to find the following sources:

I first saw this XDA-Developers thread. It seems relatively complicated. (And I haven't had much experience with the Linux shell either, so I shy away from this...)
The previous thread linked to this thread, which was 'easier'.

However, reading the instructions, I need ADB drivers or something. No clue how to get these.
Also, avast has blocked parts of the file from downloading. (Zerg rush...?) I can disable avast's web shield temporarily, if you guys recommend this method.

This article which mentions a thread similar to the previous one.
Android Forums - Sony Ericsson Xperia Pro: All Things Root Guide.

I would rather do this using as foolproof, easy, and unlikely-to-brick method as possible.

Enable USB debugging from Settings->Applications->Development.
Install SuperOneClick on your PC.
Connect the phone to the PC via USB.
Run SuperOneClick and click Root.


HDR camera and stabilized video on Galaxy S5 neo I have a rooted Samsung Galaxy S5 neo (SM-G903F). The phone runs original Android 5.1 (only rooted). The camera app does support neither HDR photos nor stabilized video recording.

Is there a way how to do do HDR photos and stabilized video recording? Maybe some 3rd party application that could do it? I would prefer single app for both HDR photography and stabilized video. Post-processing is not an option for me in both cases.

Try Open Camera. It's free also on playstore. Open Camera is based on camera2 API and supports 4K recording (if you're hardware support it too).


Does mobile hotspot have security vulnerabilities in older phones? I want to use my Samsung Galaxy Trend Plus as a mobile hotspot, for my laptop. I have installed a custom ROM on the phone -- Official Lineage OS 14.1. There are no security updates for this OS. Does this mean that the mobile hotspot connection is unsafe, or is the Wi-Fi security independent of the OS? Does it matter, as long as my laptop's OS is up to date and using a VPN?

Android releases frequent Security Bulletins to address a number of vulnerabilities at operating system and hardware level. So as a thumb rule, the newer the better and safer. But if you just want to use hotspot, it's not very hard to enforce the basic security measures.

Using as hotspot means your phone is working as a router. Routers do have builtin firewalls for better protection, and some advanced features like Port Forwarding, DMZ, UPnP, QoS, VPN, multiple AP's, RADIUS, NTP, DHCP server, DNS server, Dynamic DNS, VoIP features (SIP ALG and others), captive portal, traffic sniffing / DPI, anti-malware etc. A normal Android phone offers some of these features out of the box; the basic NAT, netfilter (iptables) firewall, Access Point (AP) with WPA2 encryption and a DHCP/DNS server.

Additionally if you are a tech-savvy, you can also define your own firewall rules, port forwarding rules, setup a VPN etc. A few things I can think of which can be easily done:

Android uses dnsmasq as DHCP and DNS server. You can edit /etc/dnsmasq.conf to whitelist you MAC/IP addresses by assigning fixed IPs to MACs (options dhcp-host= and dhcp-range=) so that only your configured devices get an IP from DHCP server.
Configure dnsmasq to listen only on local network interface and not from internet facing interface.
Android uses hostapd to create hotspot. Configure MAC filter in hostapd.conf (options macaddr_acl=1 and accept_mac_file) so that none other can connect to your phone.
Configure hostapd to offer at least WPA2 PSK encryption (option wpa=2).
Configure hostapd to hide SSID (option ignore_broadcast_ssid=1).
Configure at least 12 character long Pre-Shared Key (PSK) (option wpa_psk or wpa_passphrase).
Run a DNS over HTTPS (DoH) server like dnscrypt-proxy. Or at least set DNS server in dnsmasq.conf (option server=) to some trustworthy public DNS like 1.1.1.1.
Update /etc/hosts file and/or dnscrypt-proxy blacklist file from some trustworthy source like this one to block ads and harmful websites.
Make sure you don't have any listening ports (by executing ss -ltup) except dnsmasq's port 67 (DHCP) and 53 (DNS).
Make sure you don't have any port forwarding rules defined (by executing iptables -S FORWARD) except the one defined for hotspot.
Block all incoming new packets. See this.
Disable ICMP echo reply. See this.
Block all non-root UIDs for OUTPUT chain (except if hotspot uses some non-root UID) to ensure no apps use any data.
Also consider allowing only required destination ports like 80, 443 if you need to do only web browsing. Allow others like SIP/RTP/FTP/SFTP/SMB etc. if needed.
Uninstall all user apps to save battery and internet traffic.
Disable any system apps you find unnecessary, particularly GApps, cleaners, system optimizers, anti-malware etc.

Still if you enjoy playing with phone, consider setting up some router operating system like Zeroshell on your phone.

But even if you don't take any extra measures on phone, laptop's security is enough (for laptop) if configured properly.


i5500 update from 2.2 to 2.2.2? I have got a Samsung Galaxy GT-I5500. Actually there is Froyo 2.2 running on it. I read that with 2.2.2 there got a bunch of bugfixes released. Even though i know Froyo is quite old I never ever read about someone who upraded to Version 2.2.2 though. Everybody seems to stay with 2.2 (or switches to 2.3,...)

That's why I would like to ask if there is a way to switch to 2.2.2 even though my carrier doesn't provide it through kies???

--> I already found this page
Official ROMs for i5500
but I don't really know about the JPJ/JQ3...-Codes. Even though it says that these ROMs should be 2.2.2 I am not really sure about that, because the Codes listed differ quite a lot.

My actual SW-Version: PDA XWJQ3 / PHONE NEJPS / CSC REJP2

you can go UN-OFFICIAL , CM7 works great on it... a GB AOSP rom

Why can't I save an emergency phone number in my addressbook? I live in Thailand, and the emergency medical response number to dial here is 1669.

When I try to save this number in my address book on Android, it says "Emergency Number Cannot Be Saved".

What gives? It's probably the most important number for me to save, and I can't. Is there any way to fix this?

My device isn't rooted.
I'm saving to an address book that is synced via CardDAV.
I'm running Android 8.0.0 on a Xiaomi Mi A1.

The solution that worked was to use a browser on my computer to save the number in the addressbook instead of using the Android contacts app. I used Fastmail, but I expect Google contacts would work in the same way. This then syncs to the phone via CardDAV. After testing it, the number is synced and functional.


What Google Apps can I disable? I'm using a Kitkat 4.4.4 based phone (Samsung Galaxy S Duos 3)
For the most part I don't use G+ or Maps or most of the Google apps provided.
But I do prefer documents being backed up, so I've refrained from shutting down the google app entirely.

Being a phone of very low ram, it kinda cripples the performance. As far as I understand in Android it's not a good idea to kill apps (so normally I hibernate the stuff I don't use). I prefer having the RAM full with apps I actually use.

I'm not really sure what I should be doing with the Google apps. And I would prefer not voiding my warranty by creating a swap partition (using root)

Generally speaking, any system app you can disable can safely be disabled. Core system apps will have the disable button greyed out. You can see this if you open App info for the Settings app itself.

Go ahead and disable all Google apps you don't want.


Android Root Certificates, published list? For each version of iOS Apple publishes a list of the embedded root certificates:

https://support.apple.com/en-us/HT205205

I am unable to find something similar for Android, I am wondering if these could differ by device vendor or if they all share a common set as part of Android proper?

My goal is to have a list of public CAs which are common in both Android and iOS (some minimum version of each)

For anyone who is curious, I believe I found the answer:

  Linux: There is no central root certificate program as part of Linux.
  When running on Linux, Google Chrome uses the Mozilla Network Security
  Services (NSS) library to perform certificate verification. When
  packaged or built from source, NSS includes certificates vetted
  according to the Mozilla Root Certificate Program. For most Linux
  users, it is sufficient that once included in the Mozilla Root
  Program, users of Google Chrome should see your root CA as trusted.
  However, please be aware that Linux distributions which package NSS
  may further alter this list with additions or removals based on local,
  distribution-specific root certificate programs, if any.

  Android: Please file a bug at
  http://code.google.com/p/android/issues/entry .

  Note that, similar to Linux, the certificates included within the
  Android sources may be further altered by device manufacturers or
  carriers, pursuant to their local programs.

HTC One M8 Sprint doesn't connect to roaming partners India I am currently in India, and I'm not able to get roaming data with my HTC One M8 Sprint. I have tried several settings and several carriers but to no avail. I have called Sprint but their solutions haven't helped. I have registered for roaming and I verified this on the website. I can connect to carriers to make calls, but I cannot get roaming data.

Is there any way I can fix this without having to call Sprint Customer Support again?

EDIT

Available network operators: Aircel, IND Airtel, Vodafone IN, CellOne
Network Modes: CDMA Only, LTE/CDMA, GSM/UMTS Only, Automatic
All roaming guards are disabled.
Access Point is default Sprint World.
CDMA roaming mode is set to Automatic
Domestic Voice,  Domestic Data,  International Voice, International Data, and GSM Data is all enabled.

In India, The Official partner of Sprint in India are MTS(For CDMA/800) and Bharthi Airtel,Aircel for GSM(900,1800). Since you are using CDMA,MTS(Sprint partner) supports basic 1x data. and MTS will only work when you are in Main cities in India. :(

Why are these picture-related apps blank? I've been wondering a lot about this when it happened which I was using Walli* app yet after I have changed my ROM, maybe the app gets blank no matter how I install it. But after a time, I've also realized that there is another app called Reface with the same problem in which I can't use them because they're blank like there is no connection to the Internet.

Note: I'm using Cloudflare Family DNS on my router and Firewall settings such SPI and DOS protection.
My ROM: AOSP based 7.1.2 Android custom ROM

The problem was solved by installing Exposed via recovery instead of Magisk


Can I send a mass text in Hangouts? Is there a way to send a text to more than one recipient in the new Hangouts/GVoice integrated app?

I see how you can send a plain (phone) SMS to multiple recipients, but can you do it using through the Google Voice number(note, I don't want a MMS group text. Just a plain SMS)

Go in hangouts -> in the list of all your conversation -> click on the "plus" in the top right corner -> then select a contact. Now a new screen will appear and a grey button will show "add someone else" -> click on it and you will be able to add other contacts.

Hope it will help.


How to stop android from creating files and folders on the SD card Is there a way to stop android from creating folders on the SD card such as "Android" and "Download".
I have Android KitKat version 4.4.2.

It is an obnoxious programming practice prevalent in Android and it's apps, alright.

/system/etc/permissions/platform.xml can be used to NOT give permission to everyone, their grandmothers and their cats to poop folders and files left and right everywhere throughout your SD card, but is not the final solution... just a way to make it less bad.

If not, remember that Android runs on Linux and you can always use the rules of Linux against it... or the rules of the filesystem for instance... If the SD card has a FAT32 filesystem there cannot be folders and files with the same name... so... by creating files named "LOST.DIR", "ReceivedFiles", "Download" and so forth ensures no other folders will be created... lastly is just a matter of setting the proerties of those same files to "hidden" and the file manager to "not show hidden files/folders"...

They will still be there doing their function but just not so visually.

Ultimately it is up to the person who writes each app to store app related data in the /data partition instead of the SD card as it was intended to be.


System so slow; permanent WiFi activity I guess my Android device is permanent communicating over the Internet, without any doing of my side. This slows down the system.

Is there any way to see the actual WiFi activity? I mean I like to know which app / service is actually downloading or sending out information. I tested several task-managers with WiFi Monitoring but all do summarize. I like to know which app at this moment downloads or sends data without my doing.
Best would be a widget that shows which app uses WiFi at most.

OS Monitor might prove helpful here. Amongst others, it shows you all current connections including their stati, always along with the target IP (which you can even get WhoIs details on, see screenshots) and the app holding it. This might at least help you to narrow down possible candidates.

OS Monitor: Open connection, connection target details (source: Google Play; click images for larger variants)

Hint: To transfer data, the connection status must be ESTABLISHED.


What are the standard GUI elements called? Is there a list of what the standard elements on an Android devices are called?

I can use everything just fine, but explaining to others to "use that bar at the top" and "the button that looks like a piece of paper" and so on is a) embarrassing and b) not the easiest way to explain things. Searching for names, I always end up at the GUI-documentation, which is useful in general, but certainly not in this case!

Top bar - Notification bar
Bottom bar - Navigation bar
Standard Navigation bar buttons - Back, Home, Recent Apps
These are the standard ones in every Android powered device.
Note - The word "bar" can be replaced by "panel" sometimes.

Update:  Title bar (which has app title, search button, back key) - Action bar


Reducing upper volume level My 3 year old son is making his first steps with our Android tablet (Nexus 7). He hasn't mastered the correct usage of the volume slider so he pulls the volume to the max whenever he is using it. Is there any way to configure the maximum volume setting?

There is currently no way to limit the maximum volume.

This has been asked on XDA Developers and there was only the one response since the beginning of August.


Unable to move few Apps to SD Card I have apps such as Any.DO and AK Notepad installed in My Samsung Galaxy Y Android 2.3.6 phone. I have tried Titanium Backup and App 2 SD (move app to SD) but still not able to move these apps to the SD card at all. What's wrong? Can someone help me out here?

An app must explicitly support App2SD, or you cannot move it to the card. There are several reasons why an app might not support it:

using widgets (both mentioned apps seem to fall into this category. AK Notepad: "Pin notes to your home screen"; Any.DO: "You can even add our widget to your homescreen")
running a service

As the sdcard would be unaccessible when connecting to a computer, both things would "crash" (as they could no longer access their data etc.). Of course there's always the possibility the developer simply didn't care -- in which case you should contact him and ask.


Avoid mobile version of YouTube For some reason, either Vodafone UK or YouTube think they are smarter than my own desires and are constantly redirecting my phone to use the mobile version of YouTube.

This would be fine, except whenever I click a direct video link from somewhere else on the web (even from Google results that I got using the phone itself) I get kicked back to the mobile version's index page, with no assistance to find what I was originally trying to watch!

This even happens when I click the "Desktop" link on either my phone or Chrome through wireless hotspotting, and it's extremely irritating - especially through Chrome as that should be the user agent being "detected", if anything - device neutrality anyone?!

If anyone knows at what level this is happening and/or how to stop it, that would be greatly appreciated.

Have you set the default action for youtube links to the browser?  You may need to reset it (Settings --> Applications --> Manage Applications --> app -->  "Clear Defaults") so that you can choose the Youtube app when wanting to view a Youtube video.


Why doesn't the Gmail app delete my e-mails permanently? Android 2.2 on an LG GT540. If I delete an email from my inbox in the default Gmail application then the email is in the trash, OK. But why isn't there any options to delete the e-mail from my trash?

Is it a security feature or what?

If you check this post and the answer by Google employee : http://www.google.com/support/forum/p/Google+Mobile/thread?tid=61ec816cf6ebd668&hl=en , its known limitation rather than a security feature.

The alternative as per this post by Osky: http://www.google.ru/support/forum/p/Google+Mobile/thread?tid=2f07884f917d86eb&hl=en

  This is a known limitation. There are a couple of ways around it depending on what you seek to achieve:

  Logon from your browser and select delete forever from the web app.
  Don’t sync the Deleted items label

  I’ve chosen the second option but on the other hand I very rarely delete and am not that affected by this curious lack of feature.

  Thing is that trashed mails should be deleted after 30 days, and since I selected to only sync 4 days worth of garbage it should only be present in the cloud for 26 of those days.

  To sum it up, the trash function is flawed. If it’s a viable option for you, you can chose not to sync that label and messages that you delete from trash will not show up again on your phone.

  See Eth@n from Google comment on it in the referenced thread, looks like we can hope for the future :)


How can I bypass the headset mode? My headset jack broke off inside my phone and I cannot make calls or hear anything.  Can I turn off the headset mode?

Unfortunately not without rooting your phone. Your best bet's going to be to remove the headset jack. If it's not reachable with any normal tools, you're going to want to use something thin and strong, like a toothpick with a filed-off end, and apply a small drop of super glue to the end of it, then VERY carefully insert it into the jack, press it firmly against the end of the headphone jack you can reach, hold it there for about a minute, and then carefully remove it.


How do I transfer app data from one an s4 mini to a s5 Is there a way to transfer my app data  from one phone to another. We've done saving it to a sd card and even downloaded a back app but it only saved the app. When I transfer my games I have to start from scratch again.. is there a way around this?

Applications/Games save the user data like scores, gold amount, ammo etc in /data directory. thus you'll need root access on both of your devices to transfer apps with data. if you don't have root access this cannot be done by normal means. if you already have root access then use apps like Titanium backup or any other your favorite to backup apps, most of them have facility for rooted users like Backup app with data. Then you can transfer the backup to other device and just restore it with same application this should work for normal low-to-mid range games.

Note: This can be done with file explorer app also. just find the data directory of your game in /data folder copy it to your other device where you want data to be restored. overwrite the directory in other device. kill the app from memory and relaunch it and see if it works. (Remember Root access required for any method)


Fix Google Play insufficient storage error without rooting my phone This question is essentially the same as Google Play: Error downloading app - insufficient space, but I want to fix it without rooting my phone. Clearing Cache, uninstalling Google Play updates and using cache cleaner apps do nothing. Any suggestions?
Background
My Sony Xperia T has over 10GB of free internal space and so does my SD card. Also, I have about 280MB of available RAM at any given point in the day. Despite this, every time I try to download another app of anything larger than about 24MB, the following error message appears,

ERROR, Error downloading. There is insufficient space on the device.

Although this message appears, I can go into Settings > Storage and see that I still have over 10GB of internal storage available on the device. The picture below shows my Internal storage. Please note the available space:

One solution I have found is Something is secretly eating up my Acer Iconia A500 internal memory and I need help finding it, but unfortunately this specifically applies to someone who has 379MB remaining and can't find why there is not more. This is not the case with me because my phone clearly states I have 10GB of available internal storage.
I have already looked through insufficient-memory tag, which simply explains that I should either delete apps or move them onto my SD card. As you can see, neither of these suggestions apply to my problem because I already have over 10GB of available internal storage and over 10GB of available SD card storage space.
I have also looked through questions such as "Insufficient storage" when trying to install new app. The best answer given here is to clear data on Google Play. I have done this. It still doesn't help.

This worked for me on my Sony Xperia E3 and my Galaxy Note 10.1:
a) settings-apps-all-google play-uninstall updates (you will have to do this everytime you restart)
b) If this doesn't work: clear cache - with an app like 1tap cache cleaner or settings-storage-tap cache-clear cache.
:)


Is it possible to preserve the Device ID while doing a factory reset? Does factory reset restore the Device ID or create a new one?

I have a rooted device that I would like to restore but want to keep the ID so that I won't have the issue of creating new accounts on apps that were in use.

Is it possible to preserve the Device ID while doing a factory reset?

It is possible to restore the Device ID with Titanium Backup (root required). If you have this app installed before you wipe, you can make backups of your apps and data, as well as the Device ID.

When you factory reset your device or install a new Rom, you get a new Device ID. Install Titanium Backup and make sure it has access to its backups (usually the external SD card; internal memory will usually get wiped on a factory reset).

It will automatically detect that the Device ID has changed and ask if you want to restore it.

There may be other apps that can do this. The main requirement is that you save the previous Device ID before wiping. If you don't do that, you can't reset the new Device ID to the old one.


Can't get in recovery or normal boot HTC One M7 Please help me.

I've done something really stupid. I flashed from ClockWorkMod to Android Revolution HD on my HTC One m7.
I've got ClockWorkMod Recovery installed and when flashing was done i got stuck in HTC startup screen.
Trying to get in to recovery mode again and install my backup did not work, it just shows ClockWorkMod Recovery logo and reboots.

Is there any way to use ADB/fastboot when in the bootloader screen?

Info from bootloader screen:

M7_UL PVT SHIP S-ON RH
HBOOT-1.56.0000
RADIO-4A.23.3263.28
OpenDSP-V32.120.274.0909
OS-4.19.401.8
eMMC-boot 2048MB

The first problem was that fastboot didn't connect to my PC.
This was solved by changing computer to one with a USB 2.0.

The problem I had with my recovery was solved by flashing the recovery partition again and cleaning the cache (forget that the first time).

fastboot flash recovery clockworkrec.img
fastboot erase cache

After this I was able to get into recovery mode.

I then had a problem where Android Revolution HD did not install and my HTC One M7 was stuck in a bootloop.

This was solved by installing TWRP instead of CWM recovery, and by changing S-ON to S-OFF.
I was then able to install Android Revolution HD.

Thanks for the comments and many thanks to "bored_stupid" on XDA-Developers who solved the installation problem for me.


After upgrading the preview of text messages on my lockscreen feature disappeared I have a HTC One Mini and recently upgraded from Android version 4.2 to 4.3,. Everything went fine, but I noticed when people were sending me messages that I couldn't see a preview of them or who sent them on my lock screen. I went into Settings and Personalized settings and my lock screen feature has disappeared.

The settings have moved to the "Security" list, rather than the "Personalisation" list, but I've been unable to see previews on my lockscreen since the update even with these settings. Others that I know have experienced the same issue.
HTC just recommend a factory reset... -_-


Locked out of my Samsung Galaxy S Duos (forgot password) I had set a security password on my Samsung Galaxy S Duos mobile and unfortunately forgot the unlock password. I tried hundred's of times to unlock my phone with many possible passwords but was unsuccessful in each of my attempts. Please help me unlock my phone and send me the master code (if any) to unlock the phone.

I was under the impression that if you entered an incorrect unlock password too many times then it would ask you to enter your Google Account password to confirm your identity?

Have you not had this option when trying passwords?


Huawei ascend p7: no USB connection methods The following problem is occurring today, even though I had no problems doing the exact same thing yesterday: I have connected the phone to my USB port on my computer. The phone is charging, so there is an electric connection, however the notification saying "USB connection methods" isn't there. The computer gives no sign or reaction either. What to do now?

I have switched cables.
I took the SD card out today and I have put it back in.
I tried all my USB ports already.
The cable I used yesterday isn't working either.

I have managed to solve my problem. It seems that, due to some reason, my USB port's power limit was exceeded and it froze itself. I'm not fully sure what caused this to occur, but after disconnecting everything and resetting my USB ports it somehow worked again..

The following message occured after trying a few USB ports:

I disconnected my phone and pressed reset after clicking the popup and it seemed to do the trick. A more thorough explanation on what to do in case of this popup can be found here.


Does the Nexus 7 have a LED flash for its camera? Does the Nexus 7 have a LED flash for its front facing camera? Can somebody point me to some documentation online that states whether this is true or not?

As a Nexus 7 owner, I can confirm for you that it does not have a LED flash for its front-facing camera. In fact, off the top of my head, I can't think of a single device that does.

Documentation of a feature that isn't present is going to be hard to come by. A good verification of this fact, however, is in ifixit's teardown pictures (see steps 12 and 13). Camera and light sensor, no flash.


How to change IGN in play store? Before, I had a coc acc and I got bored so I gave my acc (gmail) to my friend. My friend then changed the ign to his name. Now that i got a new phone, I installed coc and even if my old acc is already installed, i cannot play my old acc and his ign appears at the top. How can I change my ign?  Do I need to log out my acc from his phone?

To change your IGN

Open Google Play Games.
Tap the IGN
Tap on the Pencil in the top right
Change the IGN.


Camera app that can use hardware buttons for making photo I am searching for either a camera app with hardware button support, or for some other solution that would make it possible to use hardware buttons for making photo (shutter) in a camera app.

My phone, Samsung Galaxy S III mini doesn't have separate camera button, only power button, home button, back and menu buttons, and volume rocker.  It is IMHO much easier to use hardware button than to try to hit software button on camera screen.

I think this should be possible, because built-in Phone Call app can be configured to accept call with Home button, and end / cancel the call with Power button.

This question can be considered to be continuation of How to assign a hardware button to camera which is about using hardware button (e.g. Home) to start camera.

While Is there an app for X questions are off-topic here, just a little hint: You might wish to take a look at ProCapture and A Better Camera, which both support the volume rocker for either shutter or zoom (configurable). I'm pretty sure they are not the only ones.


Where did the galaxy live wallpaper go in ICS? Since I've upgraded to Ice Cream Sandwich on my Nexus S, the galaxy live wallpaper -  which was part of Android - is gone.

Can I get the exact same live wallpaper for ice cream sandwich? It looks something like this:

You can try to switch your current live wallpapers with the Gingerbread pack the Nexus S came with. This will need your device to be rooted though.

As seen on this topic on xda-developers, you can use Root Explorer (or any other application that can get into the android filesystem, like Root Browser Lite) to switch your with livewallpaper.apk file located on system/app with this one, which contains the stock Gingerbread live wallpapers from the Nexus S, and possibly the one you're looking for.

Also, there's some really similar live wallpapers available on the Market, including one called Galaxy Core 3D LiveWallpaper, which looks almost like the one you're looking for.


Why can't music players find my audio files? On my Nexus 4, there's a folder called /sdcard/Music/ (or just /Music when browsing the phone's storage; Windows 7 calls it Computer\Nexus 4\Internal storage\Music) and I've put a lot of songs in there but the music player doesn't see any of my songs.
Why can one app (the file manager, and e.g. Dropbox) see the files, but not another app (Play Music, Apollo, Jukefox)?

Notes:

LG Nexus 4 16GB, unlocked, with CyanogenMod 10.1
(nightly build 20130212 because nothing more stable is available but there are no crashes.)
The songs are stored in the path format /sdcard/Music/Artist/Album/Song title.mp3 (simply because that's how they're stored on my media drive).

Computer\Nexus 4\Internal storage\Music\Eagles\On the Border\1 Already Gone.mp3
Computer\Nexus 4\Internal storage\Music\Kashmir\The Good Life\10 Kiss me goodbye.mp3
Computer\Nexus 4\Internal storage\Music\Christina St眉rmer\Freier Fall\1 Geh nicht wenn du kommst.mp3
(yes there's a Chinese character in there and I don't know why; it's a German ü (umlaut u) on my original Windows media drive)

I know that the songs are present and that they work because the CyanogenMod File Manager shows them and I can play them individually. They do exist!
Running Rescan SD as suggested below didn't make the files appear in any of the player apps.
I'm fairly certain there are no .nomedia files: The CyanogenMod File Manager doesn't display files that begin with a . (I renamed an existing TXT file and it promptly disappeared :)) but I used the Root Browser Lite to look through /Music and subfolders -- the only match I found was the one I had renamed, and I have deleted that now.
My Windows pc at work couldn't see the files either, but after unplugging/replugging the USB it now can see+open+play the files. (I've now revised this question to remove the Windows part.)
I'm still mystified by the fact that file-browser apps see the files but music-player apps don't.

Seeing a file name like Computer\Nexus 4\Internal storage\Music\Christina St眉rmer\Freier Fall\1 Geh nicht wenn du kommst.mp3 points to a special problem with "special characters" (such as German Umlauts) which got messed up on data transfer: While Windoze uses its own character set (MS-ANSI or wone of the WIN-12xx, depending on configuration), Android expects UTF-8 -- which is why it's a good custom to use only 7-bit ASCII characters in file names.
Due to this mismatch and the "unidentifyable character", the media scanner most likely has crashed. Which resulted in the media database not being populated, from which follows: The players think "no media files there".
Proposed actions
I'd suggest to either temporarily delete or at least rename all affected files, so that no file with "special characters" in its name remains. Then have the media scanner run again (e.g. triggering it with Rescan SD). Once that's finished, I'm pretty sure your media player(s) will find something to play (with).
That being approved, you know what to look for in the future. As said before, I strongly recommend to restict characters in file names to 7-bit ASCII -- that avoids a lot of problems, though some names might look a little strange ;)


GMail stopped working last night (CM 11) I've been running CyanogenMod 11 (11-2014112-SNAPSHOT-M12-d2lte) on my Sprint Galaxy S3 since December.

Last night I saw a message flash on the screen saying something like "Android is updating", though I'm not exactly sure since it went away so quickly.

Shortly after that I got a message that Gmail has stopped working (Report, OK) and the icon on my home screen changed to the Android robot with the "com.google.andr" text below it.

My other GApps appear to be working fine.

How do I get GMail working again?

I was able to fix it by uninstalling all updates, then updating the app from the app store. I first tried wiping cache and data like SuperThomasLab suggested but that didn't work.


How to create a 'Google Drive' file or folder shortcut, within Google Drive, on Android? (see body of question) On the web application for desktop this is accomplished by navigating to the file, clicking on it, and pressing Shift + Z.

Is there a way to accomplish the same functionality on Android? Either within the Google Drive app or thru some other means?

NOTE: When I go to a file that's in multiple locations on the Google Drive app and go to: Options -> Details, then I can see all the locations the file is in, and also remove locations, but I can't seem to add locations from this menu.

You can select the file and add to star in google drive, next time when you want to see you can directly click on starred files of folders.


How can I output video from my HTC Thunderbolt to a TV? Could somebody please detail for me a system using which one can output video to a TV from an HTC Thunderbolt? It has no HDMI port so I'll (almost) certainly need an adapter, I know. I don't really need HD quality but at least 720p would be nice.

The Thunderbolt has DLNA, so if your TV supports DLNA you can use that.  On my Samsung phone, you use the AllShare app for DLNA, but I think the Thunderbolt has another app built in.  Page 275 of the User Manual describes how to use DLNA.  This droidforums thread has a discussion of ways to use DLNA without a compliant TV, I'm not sure how well other ways will work.

There's also a "multimedia dock" that is supposed to be released shortly, it's "out of stock" until then.  That should provide a cable-based way of video output.


Is it possible to encrypt system partition with custom rom? I have galaxy s9 and i wanted to have lineageos rom.

So i unlocked bootloader and wiped stock firmware of galaxy s9.And then i installed lineageos 15.1 with twrp 3.2.3-0

Then i encrypted phone. I was thinking that by encryption device in adition to data patition, system partion also being encrypted. now i found that just data partition will encrypt and system partition will not encrypt.

so is there any way to protect system partition? in other words is there any way to encrypt system partition?

sorry  for poor english...

thanks

UPDATE :

sorry, It is possible that i am wrong or i don't understand what you mean but
I found from link below Boot verification occures when stock rom is installed and and bootloader is locked. but in my case bootloader is unlocked and therefore verifying not occures.

So i think there is no official way to check integrity of system partition and i should do another things like start a daemon in init.rc for verifying system partition or etc.

Is it true ?

And i should say i put an third-party app in system/app in twrp after mounting system partition and after restart it worked successfully.

Android boot flow

Android does not encrypt system partition as there is no confidential data on the /system. There are only standard ROM files which are already available in public domain.

The encryption should only apply to the userdata partition /data or SD Card (if mounted as internal storage). Moreover /system is mounted as read-only. So, nothing can be tampered there.


Google Play , YouTube and Gmail show error message “No Connection – Retry” Some Android apps (like Google Play, Google Chrome, Gmail, and YouTube) show an error message “No Connection – Retry”.

On the other hand, apps like Facebook, Messenger, and WhatsApp perform Okay and connect correctly to the network.

In Facebook, I can play videos, make posts, and search.
In Messenger and WhatsApp, I can send messages but I can't send images.

Can anyone help me to solve this problem?

Try these:

Clear the Cache on your Android device

To fight the No Connection – Retry error message on Google Play Store app on your Android devices, try to clear the Play Store cache since this could be a reason of this error of repeatedly getting this network error message.

To do this, go to Settings > App, scroll down to All apps and finally to Google Play Store app. Open the app details and tap the Force stop button to reach to the cache clearing button namely Clear Cache.

That’s all what you needed to do to clear out the app cache. Restart your app and you might have just got rid of the No Connection – Retry error message on the Google Play Store app.
Check Date / Time settings

In case clearing the cache did not work out for you, there can be a minor glitch in your date and time settings causing the No Connection – Retry error message on Google Play Store app of your android devices. Check the time and date since a plenty of users were facing this network error message because of incorrect time settings.
Make sure to enter the correct Google / Gmail password

Another solution is to check your Google / Gmail account password. Did you change it and forget to re-enter in on your Android device? Whenever you change your password your Android device gets a notification to re-enter it. As soon as you correctly enter your new password, your Android phone or tablet would be able to get all the Google services back on the device.
Still getting the No Connection – Retry error message on Google Play Store app?

Do a factory reset!

Of course this is the very last option to go for but you would have to do it if your Google Play Store app simply refuses to connect. Before resetting your Android device never forget to back up your data since factory reset would wipe out all the data.


pushing documents to manager's phone I want my senior managers to be able to open files on their phones, in either PDF or DOC.  The format is not really the problem.  But they are not too IT savvy.  They just want ot push a button on their phone to open an app and have a library of files there. They don't understand dropbox....

I have 2 apps on my own android phone, both religious, that contain a long list of prayers or books (e.g. the bible).  Every now and then each of these is updated automatically with new prayers or hymns or whatever.  A similar idea would be a list of recipes, which is updated automatically each time  a new recipe is available.

Is there a way that would enable my managers to open a library of files, which would update automatically with new files or newer verions of existing files whenever a new file was available? That way they don't have to 'dock' their phones, or ring up to have a file sent to them -- but the files would be automatically 'pushed' from a central site to a selected list of users.
Sounds simple to me. Is this possible somehow?

Check out the playstore. While the "official" Dropbox app might be too much for them (forgive them, they are just managers), there are others where you can define folders to be automatically synchronized. Take e.g. a look at Dropsync or FolderSync. Create a Dropbox account to share for this purpose, and configure that on all affected devices -- and your problem should be solved.


No access to the Gallery nor to the camera I've got a Galaxy Nexus and recently I cannot access my gallery or camera. When I tap both on the Gallery icon or on the camera icon I got this message "No archives available", then the app shuts down. The only way to overcome as far as now is to completely reboot the phone. Phone is not rooted.

Try clearing the Gallery cache.

Go into Settings->Apps and scroll over to show 'ALL' apps.
Scroll down and open 'Gallery'
If the 'Clear Cache' button is greyed-out, then you'll have to 'Force stop' the app first, then go ahead and clear the cache.

Exit out and try to open your Gallery again.


Root Galaxy S7 edge - KingRoot and knox Is it possible to root the Galaxy S7 edge Exynos with KingRoot leaving knox to 0x0?

If not KingRoot there are other ways? (Not CF-auto-root as the knox bit will be 0x1)

My model is SM-G935F latest version released, European.

I haven't found any root method that will work, however there is currently an exploit being refined on XDA for the S7. This is the closest that anyone I've found has gotten, so feel free to follow along:

Grant permissions to a service launched with ADB? I'm trying to get a simple accessibility service, like Google's Voice Access or Button Mapper to work on an LG Exalt LTE, running a stripped down version of Marshmellow.
The stock is missing many UI components, including system Accessibility Settings, which are normally used for turning accessibility services on or off.
I would like to know if it is possible to compensate for lack of UI with ADB.
I've tried the following:
Install the app (Take Button Mapper for example),
Its manifest declares a few permissions, that i've granted, say:
<uses-permission name="android.permission.WRITE_SECURE_SETTINGS" />
was granted
adb shell pm grant package.name.here android.permission.WRITE_SECURE_SETTINGS
I even gave it
android.permission.WRITE_SECURE_SETTINGS
even though its not declared in the permissions list in the top of the manifest.
I get this error:
Operation not allowed: java.lang.SecurityException: Package package.name.here has not requested permission android.permission.BIND_ACCESSIBILITY_SERVICE
However, It is declared in the manifest here though:
<service name="a.i" permission="android.permission.BIND_ACCESSIBILITY_SERVICE" stopWithTask="true">
  <meta-data name="android.accessibilityservice" resource="res/xml/accessibility.xml" />
  <intent-filter>
    <action name="android.accessibilityservice.AccessibilityService" />
  </intent-filter>
</service>

and thats where the problem is.
this is the service itself, and it requires a non-package-wide permission, BIND_ACCESSIBILITY_SERVICE.
if I start it with ADB like this
adb shell am startservice -n package.name.here/a.i
I get and error
Error: Requires permission android.permission.BIND_ACCESSIBILITY_SERVICE
even though I already granted the permission to the package.
I've even tried adb shell settings put secure enabled_accessibility_services package.name.here/.a.i, but still get the same error.
Bottom line:
How do I start a service and grant permissions to that service with ADB? To be clear. I already know that I can use adb shell pm grant to grant a permission to the whole package, but in this case it is a permission not required by the whole package it is declared in a specific component and I am at loss as to how to launch the component with the permissions it requires through ADB.

I believe I figured it out.
I'll use Voice Access as the example app.
adb shell am startservice com.android.cts.apps.accessibility.voiceaccess/com.google.android.apps.accessibility.voiceaccess.JustSpeakService

Next
adb shell settings put secure enabled_accessibility_services com.android.cts.apps.accessibility.voiceaccess/com.google.android.apps.accessibility.voiceaccess.JustSpeakService

Then
adb shell settings put secure accessibility_enabled 1

Then finally delete the the readout app, to avoid the accessibility features from being overwritten
adb shell pm uninstall -k --user 0 com.lge.voicecommand

I don't think there should be any errors after that, leave a comment if there are though.


How to make phonecalls on an Android AVD? I am new to Android SDK and AVDs and I was wondering if there is anyway I can enable the cellular network on an Android AVD and make for example phone calls.

You can call between AVD's. Run 2 AVD, each will have diffrent number - it is placed on window title bar, example 5558. Call from one to other using this numbers. You can also text ;]

In your AVD you simply cannot use real celluar network because your PC/Mac do not have built-in GSM modem (even if, AVD is not supporting this kind of feature).


How to clear the data usage? I'm using Android KitKat. I'm not able the clear the data usage of mobile data (Mobile) as well as Wi-Fi. Is there any option to clear the data usage in rooted and non-rooted Android devices?

(Click image to enlarge)

Somebody Please do help. Am using Non-rooted Android Device.

On a rooted device, go to /data/system/netstats/ and delete all the files there. Reboot the device and the data history would be gone. Worked on Android 4.2.1 and 5.0.2, and maddisonj and Beygi reported it works on 4.4.2 and Android 8.0 as well. It clears both SIM data as well as of Wi-Fi.

This would not reset the current cycle you would be having. I believe /data/system/notification_policy.xml manages it, so you can edit it out if that cycle also bothers you.

(Click image to enlarge; image order: before and after deleting the files)

On a non-rooted device, factory reset seems to be the only choice.


How do I block ads on YouTube in all WebKit based browsers? How do I block ads on youtube on my android device? I have tried proxy websites - hide.me and plenty others, however, they work only on a windows machine, on android, they don't work, the webpage says "javascript not enabled". I have tried ad blocking proxy apps- adblock(no root), SEVEN adclear(non play store and play store versions), Adguard(non play store and play store versions). but it seems like youTube has found a way to bypass them all. IS this possible on android? if yes, how do i make it work?

PS: Or is there any free vpn app (not free trial) which blocks ads. I want this to work on all webKit (webView) based browsers

You won't be able to block ads in the Youtube APP as long as you don't want to root your device. Blocking these ads requires changes to the DNS settings and you can't change these settings without root, nor can an app.

When you don't want to root your device the only option I see is just to use Firefox (or a similar Browser), install the Adblocker addon and watch your videos through the browser. Less comfort, but the only option remaining without root.


Why Were My Timezone Definitions Updated? I just got this update notification

  Update time zones
  New time zone definitions are available.  Time zones will be updated the next time your phone restarts.

Did any real time zones actually change or was this a bug fix?  What changed?

[

See Android source for Time Zone Rules

Thanks to wbogacz who pointed out in comments the latest change (Morocco) which is likely the cause of this update or the IANA update of 23 Apr 2020

Update Mechanism

Time zone updates (Android 8.1–9)

APK-based mechanism to push updated time zone rules data to devices without requiring a system update.
Android core libraries team provides the necessary data files for updating time zone
OEMs can choose to use these data files when creating time zone updates for their devices or can create their own data files

Time zone updates (Android 10+)

Updates use the following process:

IANA
releases an update to the Time Zone Database releases an update in response to one or more governments changing a time zone rule in their countries.
Google or the Android partner prepares a Time Zone Data module update (APEX file) containing the updated time zones.
The end-user device downloads the update, reboots, then applies the changes, after which the device's time zone data contains the new time zone data from the update.


Not connecting via usb since latest update Since the latest update on Galaxy S3 (now have Jelly Bean 4.3) my phone will not connect via USB to the USB port on my car radio. It connected before the update. What can I do to correct problem?

What protocol does the connection to your car radio use? I can't exactly speak for the GS3 but this is for stock Android so it may be similar. Go into Storage under Settings and hit the menu button (or the menu overflow) then select USB connection (or similar), make sure MTP (you probably need this one) and any other protocols you need are checked. There may also be a Mount USB option present if that the former does not work.


How can I root my Droid X with Ubuntu Linux? My sanity is at stake here. I need root but I don't have access to any fancy proprietary  OS.

I'd appreciate any help.

I have a T-Mobile G1 running 1.6-donut. I rooted it this weekend from my Ubuntu laptop. Here's what I did:

install terminal emulator from the marketplace (I didn't end up using it, but it is good to have)
installed the Android SDK on my laptop (actually, I installed it six months ago, but that's not the point, is it?)
Downloaded Universal Androot from this XDA forum: http://forum.xda-developers.com/showthread.php?t=747598
used adb install to install the UniversalAndroot .apk -- the command will be something like adb install /home/amanda/Downloads/UniversalAndroot_1.6.1.apk
ran Universal Androot on my phone once it was installed.
rebooted my phone

Then I had root. I installed the BusyBox Installer from the marketplace (note: there's a $0 version but donating is nice, too) and used that to install BusyBox. Note that I wasn't able to install BusyBox (you install the installer from the marketplace, but then you use that app to install BusyBox itself) until I'd not only unmounted my phone from my laptop but actually pulled the cable. My phone didn't want to re-mount the SD Card with the cable in.

PS. The relative "fanciness" of a proprietary OS is debatable but also offtopic.


Google Chrome for Android: Chrome Web Store Possible Duplicate:
  Does Chrome Mobile on ICS support extensions?

I have a Samsung Galaxy Y and Google Chrome for Android is incompatible with my Phone, so I am not able to test it. Can someone tell me as to whether Chrome Web Store and its apps are available in Google Chrome for Android too?

The short answer is: no, Chrome extensions (which are packaged as .crx files as mentioned below) are not supported on Chrome for Android.
This is answered in detail by the Chrome Web Store FAQ:

Will apps work on Android?
If your app is pure HTML, CSS3, and JavaScript and is hosted on your servers there is a good chance that it will work in the browser on Android. However, .crx files (including packaged apps) are not supported on Android. Users cannot install their apps onto the Android browser, but they can most likely use those apps by directly accessing the app's URL.

Automatic Power On and Off Is it possible to configure a smartphone with Android 8.1.0 to power on and off at specified times?

Some OEM ROMs offer such a functionality, most do not. You can check your device's settings, if there is such an entry. If there is none, then it is not possible. So, the answer to this question will be a yes and no together. It will depend on which smartphone you have.

You can certainly not achieve this with 3rd party apps.


Is Adobe Flash deprecated with regards to Android Devices and Apps? I'm looking at all the cool new Android tablets, but the ones that really catch my eye (with regards to size, resolution, processor, and memory) don't seem to support Adobe Flash. Like the Barnes & Noble - NOOK HD+ BNTV600, At least Best Buy says they don't (I haven't looked into much yet.) Most of the devices I've been interested in run Android v4.0 and seem to have good processor/memory specs.

I haven't done any flash type programming in a very long time. However I do want to get more involved with Android products/app development. If it's just a software/driver type issue or something that can be overcome by some tweaking I'm fine with that. However if Flash plays a big role then I should probably just get a device that supports it!

So my question is, how necessary is Adobe Flash, and in most cases (for devices that don't support it out of the box,) is it addable/installable?

Adobe Flash has been deprecated starting Jelly Bean, for reasons only Adobe knows. However, there are still workarounds for installing Flash.

The trend in mobile (Android) development now is using native Android, or HTML5. Flash is discouraged, although there are still Flash websites around. Phones with older versions of Android may be able to access them.

Related: Why does Jelly Bean no longer support Flash?

Can Android run on an iPad ?

Please answer only if you are 100% sure (or even better if you tried)
If yes, should I use a jailbreaker ? Could you suggest me one ?
If yes, what are the limitations.. are the applications running on it without issues ?
If not, why... is there a good tablet to test Android applications ?

thanks

It would seem as thought it has only so far been developed to be booted on iPhone 2G and 3G devices. It's mostly up to the interest of keen developers whether it would be worthwhile attempting such a feat, I would assume whatever exploit used to run Android on otherwise locked down Apple hardware would be different in later hardware (yes, this means an iPad).

"Please answer only if you are 100% sure" - Then yes, an iPad COULD theoretically run Android because of the open source nature of Android allowing it to be ported to various devices. Anything is possible when you put your mind to it, it's looking at the realistic feasibility and time vs reward involved though.

How to deal with "short GSM IDs" in Tasker My "cell near" in Tasker looks like this:

GSM:4321.99011048 / 0
GSM:4321.99011052 / 0
GSM:4321 / 0

What is that short ID? If I take it out, my profile sometimes triggers as "leaving" even when I stay in the same place, but if I include it, my profiles "enter" task triggers even when I'm miles from the location

I never used Tasker, so I can only guess, but mobile cells are usually identified with four numbers: mobile country code, mobile network code, local area code and cell ID. Given that these are the numbers that are available for mobile cells, Tasker has to somehow derive these numbers from the ones I mentioned. I have no idea how, because I don't know the cells around you (and around here most of the cell IDs and local area codes have 5 digits. You can check yours too, with some other app, I use OpenSignal, which can give me the LAC/CellID).

As far as I know that 4321 can't be the mobile country code (it would be 3 digits, 432 is Iran) or the mobile network code (3 digits at most, only 2 digits in most countries), so my guess it that it's your local area code. And the other number after the period your cell ID, maybe. If my assumption is true, then it could mean something like that the line with only your LAC makes the app detect the local area with the mobile cells visible from the given area. It would mean that if you include the line then the app would think that you are in that local area even if you don't see any of the cells that you usually do when you're at the location, but you see cells from the same local area. That could mean being miles away. The maximum range of a GSM cell can be as much as 35 km. And if removed it could mean that the app would detect that you are not in the local area in the moment it can't detect the nearby cells temporarily for some reason. (Which can often happen.)

But this is just a guess.

Another guess is that 4321 is indicating byte order for some identification number (maybe one of them mentioned above). But then I have no idea why would the app behave like it was described.


Is there a way to set app-specific volume? I'm looking for a way to set the media volume depending on the app being used.

I generally keep my media volume down fairly low so as not to annoy my fellow humans overmuch; while playing Angry Birds, for instance.

When I go into Doggcatcher, though, I generally want to crank the media volume way up, because I'm listening through earbuds or my car speakers and need that volume way up.

Not such a big deal, but if later I go back to Angry Birds and I forgot to turn the volume back down it wakes up the whole house.

This is exacerbated by the fact that the media volume does not follow the "Sound off" setting (accessed by a long-press of the power button).

So, is there a way to do what I want?

(Android 4.0)

If you have tasker or a similar scripting app, then i guess you could "record" a sequence of actions to be undertaken each time a particular app is started / in focus.

Nope. I had the same issue and google support gave me no answer but factory reset, as did the samsung representative i spoke to. I have  a galaxy note 3. You can try unlocking from "find my phone" on samsung website if you have a samsung phone and have the services set up... or try reseting password through another phone with ADM... but if not, you'll have no choice but to factory reset, which is what i had to do.

Nexus 5X, Gmail draining battery after may update Ever since the may update, the gmail app has been consuming a crazy amount of battery.  My battery used to last like 16 hours, now it's only like 5 hours.

Change title of phone when connected to Windows PC I inherited my Samsung Galaxy S4 phone from the employee who preceded me in my current position.

When I connect the phone to my Windows 7 laptop, it displays in Devices and Printers with a name matching that of the former employee.

There are none of his accounts left on the phone.

The phone is running Android 4.3.

How do I change the name of the phone I see in Devices and Printers?

UPDATE: I think this name is a Windows setting.  I think I was seeing an old title, from when the phone had accounts belonging to the other employee.

There was another device under Devices & Printers called Galaxy S4.

I right-clicked on the device with the old employee's name, clicked uninstall.

When I disconnect and reconnect my phone I no longer see a device with the old employee's name, but I do see "Galaxy S4".


How to get rid of OTA software update notification? I upgraded my Nexus 4 to Lollipop a few days ago but I don't like it. I'll leave out my reasons because they're not relevant here. I wiped my phone and installed a clean stock 4.2.2 version instead. I'm happy with this.

Not long after, Android automatically downloaded the 4.3 upgrade and notifies me with the choices "Later" and "Install". I don't want to do this upgrade.

How do I:

get rid of the notification, and
remove the downloaded update (to free up precious storage space).

I have already tried choosing "Later" but the same notification immediately reappears.

Based on Google search results, I also tried going to Settings > Apps > All > Google Services Framework and unticked "show notifications" but it still appears. Force stop or disable also doesn't seem to help, so I've re-enabled the service including notifications. I didn't see any other apps in this list that sounded relevant - did I just not see it?

You can disable these notifications by unchecking the notifications for Google Play Services [Not Framework]. This fixed my problem on the LG G3 and I assume it will on all other devices.

The best option is to click and hold the notification and then select 'App info', which will take you to desired app info for that update notification. Then uncheck the notification option there.


Does installation of CustomRom chage the partition I have some basic question abt customROM

1.When you install customROM, does it change/recreate the partitions in previous ROM   stockROM/Custom) or it just installs the ROM in the  existing partitions (like windows)

2.What is ROMSlot, is it someting like MBR in windows ?

3.Is there any customROM that will unlock the bootloader for me and install itself.

4.Does cynogenMod works in ANY DEVICE  (i.e. Chinese )

No, flashing ROM will not change your partition table.
No, flashing ROM won't unlock your bootloader (I think that you'll, in fact, need to be using unlocked bootloader to flash a ROM)
CyanogenMod is made for each device separately. If it's available for your device, you can install it. Go to their website to see if there's an official or unofficial port of CyanogenMod for your device.
