USB-C port not working as a host to use with USB OTG or HDMI adapter I have a Samsung Galaxy A9 which I'm trying to connect to an external HDMI display by the means of a commonly-found USB-C to HDMI adapter like this one. Connecting the USB-C input "lights up" the adapter, and Android shows the adapter as charging, but it does not work with multiple HDMI cables and monitors.
After searching everywhere with no avail, I noticed that the notification area shows that adapter - briefly - connects and disconnects multiple times before it disconnects permanently (while still showing that the adapter is being charged).
Some screenshots:

Here the USB connector is shown connected (it disconnects soon afterwards, but I couldn't get a good shot of it) and charging.

Now the device has "disconnected" (I presume?) yet still charging.
I also tried forcing the phone to act as a host of the connection in the settings, but that also fails.

How can I enable USB OTG in my device (if it's not already enabled)? I take that the device should be able to do this screen sharing since it was produced in 2018, and I've seen older devices in videos performing it just as well. What can I do to fix this USB error and enable other things (such as a USB hub or a keyboard) to be used together with the phone?
Similar questions to this one are very old and not quite close, so that's why I'm asking again.
Many thanks, feedback is appreciated.

It turns out that my device is not HDMI-compatible and will not transmit over that adapter (or any other, apparently).
Props to Robert for finding a (generic?) listing over here:
https://en.everybodywiki.com/List_of_devices_with_video_output_over_USB-C
(In case anybody else is googling this and can't find a solution, I highly recommend checking your device against the list above.)
Whereas at first I was a little skeptic of this insight, buying a USB-C to USB-A adapter and testing out with other devices like a USB mouse or keyboard confirmed that the port itself has no issue - it's the HDMI output that has a problem.
I'll look into alternatives on how to cast my screen in another way.


Any android app capable of storing "unsent tweet" then send it out when internet connection is resumed? As question, I have found something called offline twitter, but seems that it is broken in my HTC ChaCha, as I can't copy the "pin number" from twitter site back to offline twitter. Thanks.

A number of 3rd-party "social" apps have this feature.

Personally I use TweetDeck.  When Internet connection is not available, it will save my tweet, and throw a notification saying that it will be sent when connectivity is re-established.


How to restore files on SD card protected by NQ vault? I changed my Android mobile phone from one carrier to another. I installed Vault app from the Google Play store, and placed the old SD Card from the previous phone into this new phone. After installing the vault software in the new phone, I am unable to restore data (photos, videos) from old SD card.
My old phone isn't in working condition so how do I restore these files?

There is a related post here which indicates that vault app is phone specific How to restore files on SD Card that was protected by Vault app? which indicates it is not possible, more so since your old device isn't working

Even for premium vault members it appears to be the same (need to use old phone)
https://help.nq.com/entries/24327737-I-just-got-a-new-phone-how-can-I-transfer-my-Premium-Vault-service-to-the-new-device-

But both these are time lined 2013 so it's best to reach out to nq vault help and post your outcome here for benefit of others

Edit

Short answer : NO, unless you are a premium subscriber and made a cloud backup

Long Answer : I mailed NQ, since I had the app on my previous cell and
was debating to go premium. Their reply, you can quote  request (#239838) to follow up

  Carrie (NQ Mobile US, Inc.)

Thank you for contacting NQ Mobile Customer Support.

  Unfortunately, if you no longer able to access the device, it will be difficult to recover your files and information from the Vault at this time. This is because the Vault files are saved locally on the device itself and the only way to either backup, restore, or move those encrypted files would be by using the Vault application on the original device. There is no other way to do so via a computer for example, unfortunately.

  If you ever made a backup with our premium Cloud Backup (Vault Online) feature in the past, you should be able to restore your information to the last backup on a new mobile device by tapping " Cloud Backup (Vault Online) " in the application, signing into your NQ Account, and then tapping the green "Restore" button. If you have never made a backup or were never a Premium User, unfortunately the files are lost and there's no other way to recover them. I do apologize for any inconvenience this may cause.

  If you had Premium Service on your old device, however, I can assist you in transferring that Premium Service over to your new phone.

There is a lesson to be learnt here, before trusting sensitive data to such apps, evaluate all contingencies before you do that


Slide to unlock appears even when pattern lock is activated. How can I get straight to pattern lock mode after screen is turned on? I thought the whole idea of pattern lock is to replace the 'slide to unlock' thing with something safe. Well I don't know if this is a bug or not but I have to 'slide to unlock' first before I can use my set pattern to unlock the phone (the epitome of redundancy). How do I get straight to pattern unlock after turning on the screen?.

By the way I own an Xperia Neo V running Sony's skin, Timescape UI

Are you running a custom ROM?

I know that in cyanogenmod you can choose to keep the slide to unlock screen and then your unlock pattern. That's the way mine is set up.

To turn this off (in cyanogenmod 7's case) follow these steps

Go to settings
Tap Cyanogenmod settings
Tap Lockscreen
Tap Unlock options
Then uncheck the top option labelled "Skip on security"

You might be able to find the "Skip on security" setting somewhere else on your phone if you aren't running an official version of cyanogenmod or if the rom is only based on cyanogenmod


Is there any sniffer aplication for Android 2.2? Is there any network sniffer program for Android 2.2 similar to Wireshark for Windows?

There is Shark that does just this, it requires root, there is also Pixie, but it too requires root.


How do I sort whatsapp media files according to sender Is it possible to sort out whatsapp media files with the name of the sender?

By copying the photos to your computer you can sort it by different exif details like camera taken, date, location etc. So try cleaning and organizing by that. you can copy back the needed photos to your mobile later. Hope it helps.

But as far as I know, there'sno such option.


How can you tell which version of an app is on your Android phone? I was just browsing through the AppBrain Android store and saw as one of the popular downloads Gmail.

This made me wonder how to see the version info of an application on my Galaxy S mobile phone.

How can I tell the version so that I may update this application to a new version?

Go to Settings > application settings > manage application then tap on the app. It'll say the version you are running under the name. You shouldn't have to check though; If the app in the market doesn't say "Installed" then you don't have the most recent version.


What is causing my screen to not turn off after the established time? Screen is set to turn of in 2 minutes. But this does not happen.
How to find the cause?
If relevant I have a Samsung Galaxy Tab P7500 running Android 3.2.

UPDATE
To clarify questions from the comments:

Device is not connected
I have numerous apps installed, so I can't check who is holding the screen by uninstalling it one by one. I want to find the possible malware by some tool or programmatically.

You can use Wakelock Detector to find out what app is causing the behaviour. Remember to read the correct procedure from the app's info:

  How to use:

  1 Install the app

  2 Charge your phone above 90% and unplug cable (or just reboot the phone)

  3 Give it a time (1-2 hours) to accumulate some wakelock usage statistics

  4 Run “Wakelock Detector”, it will display wakelock statistics for you!

  5 Check the apps on the top, if they show very long wakelock usage time then you found the cause of your battery drain!

  *Note: Wakelock Statistics are gathered since Step#3


Is there an app that will list my phone's info in an easily copy/paste-able format? There's a great Add-on for Firefox called InfoLister, all it does is provide a nicely formatted list of stuff and versions, for example here's what it lists for me:

  etc...

  Themes (1):

  Plugins (13):

  Garmin Communicator Plug-In
  Google Talk Plugin
  etc...

Are there any Android apps that can generate an easily copy & paste-able list of the phone's version, etc. all in one place? Basically the stuff that appears in Settings -› About phone.

Well out of my own curiosity, I made this to start:

https://github.com/dieseltravis/AndroidBuildInfo

Here it is running on my Moto Flipside:


Force stopping bloatware apps on android phone I don't use Facebook and don't intend to. Can I force stop on android phone (LG Stylo 4) without destabilizing anything else? I have installed WhatsApp which I know is owned by Facebook but which I think (hope) functions independently and hopefully would not be impacted by stopping Facebook.

Yes, WhatsApps runs separately from Facebook, despite them being owned by the same company. You can safely force stop Facebook.

If you don't intend to use Facebook, the more logical solution is to remove it, which will prevent it from doing anything and free up space.


Can I use Droid Explorer to migrate my apps and app data from one device to another? Examples:

Migrate from old Firestick (small one) to a new one?
Migrate from Note 4 to Note 8?

Or is ADEBAR or something like that a better solution?

If Droid Explorer is the solution can anyone point me at the steps? Not seeing anything after some searching - tho to be fair, this app came off a post in a StackExchange post.

This is the closest to migrate that you can do without additional apps. From what I know, use Android 6 and newer with a valid Google account where all Playstore apps are recorded. I have not tried on older than Android 6 for these to work.

Enable its Google backup and auto sync options. Activate all application that have a backup/restore, such as Whatsapp.

When you login to the new device, the contacts, wireless settings and those auto backup can be restored. The respective Android apps from Google Play Store are listed as Library in My apps & games. Select and install back the required games.


Where are IP addresses stored on Android? Where are IP addresses stored on and Android device? In what location on disk, or otherwise; how are they stored?

Under Settings, Wi-Fi, , Modify Network, Advanced Options, IP Settings, you should have a choice of Static or DHCP.  Choosing Static adds input boxes for IP address, Gateway, Network prefix, and DNS.

If you don't have this, I suggest trying a third-party app such as WiFi Manager.

Finally, if you're really talking about where in the filesystem this is stored, it's in /data/misc/wifi/ipconfig.txt, and is managed by the WifiConfigStore class. This is not a public API and is only used from class WifiStateMachine.  However, you can find out the format of this file by viewing the source: WifiConfigStore.java.


What system app stores the cellular network settings? Before installing a new ROM, I backed up all data from my system apps using Titanium.  I installed the new ROM, and also put in a new SIM card from a different network (so it was in on first boot-up of the new ROM).  Everything worked great on the new network, until I restored my backups.  The settings for the network (matching the current SIM) were overwritten by the settings for the old network (matching the previous SIM), and data completely stopped working.

My question is, what app stores the data network settings?  If I know then I can restore data for everthing except that app (or apps) and not need to start from scratch if I change SIMs again.  Additionally, is there any way I can trigger the phone to go "Oh look, the settings don't match this SIM, how 'bout we update the settings?"

I have a Samsung Galaxy S Vibrant running Froyo (Bionix v1.3 with TouchWiz).

I would think that the following would probably be likely candidates:

TelephonyProvider
SettingsProvider (maybe)

Does the data network work if you reboot?
What if you restore with the "old sim", then put in the new sim?


Is 'Spy Phone App' safe to use? I am thinking of using 'Spy Phone App' for tracking different whatsapp accounts. Is it good and safe to use? Have anyone used it? Kindly advice me.

Note: It isn't available in google play but you can find it in google search.

The best way to assess this tool is to read the Terms of Service, which is publicly available here.

A relevant part is this subsection of "Installation and use of software" on the tracked users' devices:

  You can only install and use this app on a device which is your
  property, or for which you have written permission to install the app,
  from the owner. You must make anyone who uses a device on which this
  app is installed, aware of the fact that their internet and phone
  activity is being monitored and archived. Failure to do the above
  might be considered breaking of federal and state laws. If you install
  our software onto a device which you do not own, or don’t have proper
  consent to do so, we will fully cooperate with all relevant
  institutions. Spy phone app is not to be used to ‘Stalk’ or ‘Harass’
  anyone. Spy phone app software must not be used to monitor the
  smartphone and private life of a spouse, girlfriend, boyfriend, child
  over 18 without their written consent. Please read all relevant
  legislation before purchasing and using this app.

Considering the possibility you are asking whether it is safe for you (as the tracker), this is the relevant subsection from the "Privacy policy":

  Our app does not collect any additional info from your device than the
  ones required for its successful operation. Your data is in safe
  hands.

And this further down:

  The data collected includes but it is not limited to phone calls, gps
  logs, sms logs, system logs. We do not collect passwords or credit
  card numbers.

So, the conclusion: You can only feel safe about this app if you lower your defenses and those of the "friends"/"active voluntary participants" in your scheme.

Unsolicited personal opinion - it's probably a good idea to evaluate why this app is not distributed via Google Play Store.


ICS Navigation app change default from walking to driving? When I try to add a new "Directions" shortcut to my home screen, the shortcut interface defaults to "walking" directions instead of "driving" directions.
Also, when I use Chrome To Phone to send a directions page to my phone, it shows up in Walking Directions mode.

Is there any way I can change this default, so my phone assumes I'm talking about Driving directions first?
It seems like it would be a better default.

It's to do with the transport mode you're using when you tell maps to ask for directions.  Pick a point on the map.  Press and hold till the bubble comes up.  tap on the bubble, choose directions, now the directions panel comes up with from and to lines and under that will be the choice driving, public transport or walking.  choose driving then press navigation.  that works for me after I was suffering the same problem as you.  Hope this helps


How do I use a U2F key to log into google account in firefox on android My u2f key is already setup and working as the second factor on my google account, and I've used it many times, including using it with this tablet via usb.

I now want to log into my google account in the firefox browser on my galaxy tab a. When I try, I only get the option to enter a backup code.

I checked about:config and security.webauth.u2f is set to true.
Security.webauth.webauthn is true.
Security.webauth.webauthn_enable_usbtoken is true.

What am I missing here?

Well, it's not a complete answer, but Google has apparently added some behavior at this point: There's now a URL (https://g.co/sc) given when you get to needing the second factor that you can use in another device to get a one-time use code.

I was able to switch to chrome on the same phone and use that URL. Chrome then prompted me for my FIDO key, which worked fine and I was able to login to firefox.

In no way is this ideal, but at least it's a workaround.


How to know whether TrustyOS is running in Android mobile or not I'm referring TEE(Trusted Execution Environment) for Android Here. Can anybody help me to check whether any device is runnning Android along with Trusty OS?

Can I Change My Device Info For Reach Another Version of an App On Play Store? For example, I have a snapdragon phone. But I want to reach an app's intel version too. Because tablet of my litte cousin can not reach to WiFi. And he want to download a free game. When I download and give it to my cousin, game won't work cause different proccessor(intel thing). So I want to get this app's intel version. How can I do this?

I think its possible with edit my device info but I dont know which info and to what.

Edit: And if I edit my build prop's ro.product.cpu.api, will my device get hard brick?

As I've already pointed out in my comments on the question, modifying your device's build.prop to appear as a different architecture is a very bad idea. It won't "hard-brick" your device, but certainly will have side-effects you won't like (e.g. the device might refuse to boot up at all – not sure what exactly will happen, as I was not yet bold enough to try; if you really want to know that, either try (not recommended if you don't know a way out then) or ask that as a separate question).

Concerning your real goal: As pointed out in my answer here, you can use Raccoon on your computer for that.

While the other question focuses on apps you've bought, Raccoon of course also works for free apps. For different device architectures, you will need to create different profiles: DummyDroid can create the required "GSF IDs for mock up devices" if you don't know the one of yours, based on the given device's build.prop. If that doesn't work out, or you want to use the "real ID", please see my answer here on how to obtain it from your device (or from that of your cousin).

Drivers for Nexus 4 for Windows XP I don't have any software on my laptop for my Nexus 4 drivers. Where can I get the driver software to download it for my Nexus 4 for Windows XP?

If you're looking for drivers that will allow you to connect your phone to the PC, you can install the Universal Naked Drivers found on XDA. This is compatible with Windows XP.

NOTE: This driver is by 1wayjonny, and works with Nexus 4, Nexus 10, Nexus Q, and Nexus S.


gmail app not updating emails My Gmail app that I have installed in my Android 2.3.5 phone has stopped receiving or sending new emails since the last couple of days. What can I do to fix this synchronization issue? Any suggestions?

I've had the same problem since upgrading my ROM.
The solution i'm going to present will lead to the loss of unsent emails, so copy them to somewhere.

You have to clear the application data.
To do that you go to:

Settings > Applications > Manage applications

look for Gmail and Clear Data

It will synchronize again with Gmail servers and the problem should be solved.
Send a test e-mail to yourself.


Error opening terminal: Screen I just installed nano on my Nexus 9, which is rooted.  However, when I try to run nano, it says "Error opening terminal: screen."

bash-3.2# nano
Error opening terminal: screen.

Any help would be appreciated.

This would be better as a comment, but I don't have enough reputation for that. I'm happy to help you troubleshoot though!

Basically to answer your question it would help to have more information. How did you root your Nexus and what version of root are you using. How did you install bash and nano?What is your TERM variable set to? Are you using a terminal emulator or adb? If an emulator, which one and what is the terminal type set there? (Look in settings). If you set both of these to something nano can handle this might solve your problem.

Also Google your error message and "nano" - it seems others have had and solved similar problems.

By the way rather than responding to me it would be better if you changed your question to include information about what troubleshooting steps you took. If we solve the problem I can also edit my answer to fit the solution.


SD card limit says 8gb, Can I get a larger sd card to work? I'm thinking a buying a new phone, but it says the external sd card size limit is 8gb.  Can I do something to increase this to 16 or 32 gb.

Details:  phone: I-Mobile IQ 5.3

http://product.i-mobilephone.com/preview/53/1312

Android 4.2,  4gb rom, 1gb ram.

I don't want to root this right away.

The price is less then $200. unlocked.. Don't have $600.

Generally, you need to follow the max external SD card size limit. Otherwise, your phone might not be able to read the bigger-sized SD card.

Recover data from encrypted SD card I have an HTC Butterfly phone and what I did was I ordered a new SD card with much larger memory. I had my previous card encrypted already and took that out and inserted my new card in.

The phone asked me to encrypt it again else the new inserted card would remain read-only. So, I did that. And now when I insert my old card in my phone again I cannot access data of my old card through the phone as the phone says the format is incorrect or the card is damaged and in order to use it I need to format it again.

Is there any way in which I can access the data from my old card? I cannot access it through my PC as it is encrypted already.

I have Android 4.3 and HTC Sense 5.5

Deleted photos, yes. Encrypted photos, no. If PhotoRec or ZAR can't recover them, they're gone. (ZAR even bypasses the CPU in the SD card, so it doesn't matter if the card is accessible or not.) and they can only recover data that looks like photos. "Data" that looks like random data (which is what an encrypted file looks like) isn't "recoverable" with file recovery techniques.
The encryption algorithm used in Android, due to the limited processing power, isn't unbreakable.
This is the reason that ALL important files should be backed up to at least 2 independent devices. If you don't have the time to do the backup, the files weren't that important.


Turning on screen, flickering.. with logcats Flickering is only noticeable in 10/255 and above brightness, in 255 brightness the flickering is extreme and it only occurs in the bottom part of screen(almost the size of keyboard)... So whenever I turn off the screen then touch the screen multiple times then turn the screen on again there will be flickering. It also happens sometimes  if I plug the charger while screen is off.btw im rooted but this flickering was here since before i rooted. I tested lots of things like disabling almost all system apps and it was still there.

This live logcats are screenshotted right after turning on the screen so flickering occurs when it was created. I also noticed that flickering can only be seen when there is a layer of darkness created in the screen such as pulling the status bar, the home screen, and in the toast notification(just the whole bar of the toast notfcation)

So what exactly causes the flickering according to the logcats? amy clues on how to fix it?

https://drive.google.com/folderview?id=0B6cwi1mZj5KEUnNER1hQeW9jVVk

The symptoms you describe sound much more likely to be a hardware problem than a software problem. You probably need to get the backlight of the screen replaced (or the whole screen, if it's an OLED screen).

You shouldn't have rooted your phone when it had an existing problem, if it was still under warranty. As things are, you'll need to pay to get your phone repaired. Take it to your local phone repair shop.


How to update my android OS? Before two months my mobile phone was up to date in Android OS. I have updated my phone Nexus 5 to Android Lollipop.

And After on Month, My mobile phone display was damaged,And i sent it to the LG service committee, because it's on guarantee.

After the mobile service process completed, at once i have made an update process. But it was not installed the latest version of Android(Android 5). Up Till now i do check for update, I display nothing for my query. How to fix this problem?

Do you have any idea about what the service team has done to my phone?

Try a hard reset and then update your phone by going to Settings > About Phone > Software Update

If you would want to do a manual update then you flash your device and then install Lollipop image. For more instructions see this link


i'm totally ignorant and my unrooted tablet is stuck in a boot loop I have an unrooted Smartab ST1009x, which did not have ADB enabled.

After a system update, I think I interrupted an app update [I tried to disable the Google app while it may have been mid-update; I admit I wasn't paying attention.]
It instantly rebooted and has been stuck in a boot loop ever since.

It looks like I could just do a factory reset, but I really want to recover some files from an art app, so I'd like to avoid that.

It seems like applying an update via an SD would repair the damage I did.
Unfortunately I'm completely ignorant when it comes to programming. Everything I find on the internet about doing this presupposes I rooted my machine or I have ADB good to go -- I don't! Heaven help me I'm not even sure what version of Android I'm running.

Does this mean I'm out of luck?
If not? Maybe there's a good walkthrough (for someone unfamiliar with Java and programming, real outsider idiot-friendly stuff) that I didn't find -- can you please send me a link?

I have been through the same situation
 After the factory reset, I faced a similar situation. You can take out the SIMs and memory card and do a factory reset. After the factory reset, latest Android update pre-installed with Google Siri which has speech recognition and face recognition technology and I can assure you, once you get used to it, it can do wonders.

Terminal Emulator Problem Mac Spoof I'm trying to do a Mac Spoof from my Motorola Moto E (Rooted of course!) but I have a problem cause i'm quite sure i'm not succeeding in spoofing!
Well, I installed BusyBox and Terminal Emulator.
Then I go to Terminal Emulator and wrote:
"su"  (so I have permission from SUPERSU)

root@surnia_umts : /  # **busybox ifconfig wlan0 down**

root@surnia_umts : /  # **busybox ifconfig wlan0 hw ether [New Mac]**

root@surnia_umts : /  # **busybox ifconfig wlan0 up**
root@surnia_umts : /  #

Then the terminal doesn't say anything else.

After that,  the wifi from the device doesn't work anymore ( I have to disable and renable the wifi to make it work again) and of course the mac didn't change...... anyone has an idea, need some help, I am new of Android!!!

It appears that Android MAC Spoofing can only be accomplished on "Open" access wifi networks. Try to change the last three sets of numbers from the original mac address. The first three sets identify the adapter/manufacturer, changing them may cause authentication issues.


Samsung Galaxy S6 Charger Cable My Samsung Galaxy S6 fast charging cable has broken and I was wondering whether I needed to buy a cable specifically for fast charging, or just a regular media cable.

The fast charging plug socket isn't broken, it's just the cable.

Fast charging is not related to the cable - the circuitry is in the adapter and device. That said you need to buy a cable that can carry higher amperage , allowing fast charging speed ( cable per se doesn't increase the speed but because it permits more power, speed is increased)

Thicker the cable, better it is ( thicker cables have lower AWG number )

Go in for a cable like
Tronsmart cables at a price comparable with budget cables. These are 20 AWG thickness for charging (provide best charging) 28 AWG for data (thinner thickness doesn't affect data transfer speeds)

For technical details of a good quality cable see my answer here

I am not affiliated with the product- a very satisfied user


How do I configure calendar " leave in X minutes" notifications to use non-driving travel times? I think the Calendar reminders that let you know when you have to leave in order to arrive in time for an event have the potential to really make my life easier, but the travel times are all calculated as if I were driving. That's actually a relatively rare case for me; I'm far more likely to be using public transit or walking. I'd there an way to configure Calendar to use transit, walking, or biking times instead of driving times? Even better would be a way to override this setting for an individual event.

Well, I think you are talking about the Google Now notification, right?

If so, you have to change the option on the Google Now app, not on the Calendar app.

To do so, you go to Google Now(tap the search bar on the top of your home page) then you'll see the card that estimates your arrival time to your destination, you can see like three vertical dots, tap there and hit Settings, now you set Transportation Mode to Public Transit.

From now on, the card will notify automatically the time you need to arrive by public transportation.


Android browser: how to revoke ssl permission on a single site after giving it? I'm building a website under ssl certificate. It just works on desktops but android browser argues that the ssl authority is not trustworthy. So to see the staging site I told it to just consider it trustworthy. Now it doesn't complain anymore.

But now I have to find a way to make the browser not complain for the ssl authority with any user, but I have no way to test the changes I'm doing, because now the browser considers the site ok. I want to set it back to original settings and get it complain again :) I cannot find a way, it seems I have no access to ssl/websites exeptions.

The certificate has most likely been added to your "trusted certificates". You can delete it in Settings › Security › Trusted Certificates then (Settings referring to the Android System Settings, not those of the browser used): chosing the "User" tab should display certificates you've added as user (as opposed to those the system already brings along, or you might have added manually with root powers to those).

In case the browser used ignored the central certificate storage, and dealt with it itself, you can either try finding the corresponding place in the browser's own configuration pages – or simply drop it all (all the browsers data, including cookies etc.) by going to Android's Settings › Apps › All, scrolling the list to find the browser you've been using, tapping its entry, and chose to "Delete data".


Rooted the phone and installed cyanogenmod. How to get back Sense UI? I have a HTC Desire comes with Sense UI when bought. I rooted it and installed Cyanogenmod. Is there anyway I can get back my Sense UI. I don't mind removing Cyanogenmod.

You're going to need to install a Sense-based ROM. CyanogenMod is basically a customized build of the Android Open Source Project (AOSP) code, which is released in source form by Google. They use only open source components, and Sense is a proprietary, closed source UI made by HTC.

Installing a ROM with Sense is very easy, though. The procedure will be just like flashing CM - boot into recovery and flash a .zip file with the ROM that you want (alternatively, install via ROM Manager, whatever you prefer).

There are custom Sense ROMs as well as "stock" rooted ROMs floating around. The XDA boards have a handful of each. You can find a rooted stock ROM here, though, if you're looking to go back to the original system as provided by HTC (but retaining root).

Edit: I answered this under the assumption that you have no backups to work with, but if you used ClockworkMod to create a backup of your system before installing CM7 (which is highly advised for any future readers out there!), you can restore that backup and...well, be back where you were on a stock rooted system. After all, that's the point of the backup!


Error Sideloading Android L I am trying to update my Nexus 7 (2013) WiFi to Android 5.0 with adb sideload. I get this error:

Finding update package...
Opening update package...
Verifying update package...
E:footer is wrong
E:signature verification failed
Installation aborted.

I have the file (razor). It is a .tgz file, so I entered into the command prompt (I opened inside SDK platorm-tools) and ran adb sideload beaverlog.tgz and it gave me that error (beaverlog is what I named the file). The instructions also said to do it as a .zip file but I couldn't find a .zip file.

Since you have a .tgz file, I would assume you downloaded the factory image for your device. You cannot use adb sideload with those archives. They are not packaged for that. You note in your comment:

  The instructions also said to do it as a .zip

...and the instructions are correct. If you find that your environment is deviating from the stated instructions, then it is quite often an indication that you are not following the process the way it is intended. In this situation, luckily, the recovery system bails out without damaging your device, but in the future it would be a good idea to take some care when attempting to install images to your device.

The top of the factory images page you got the update from has different instructions for flashing the contents of the archive. You need to either follow those steps or obtain a copy of the update in a .zip format that is compatible with recovery-based installation.

If you intend to use the factory image, the proper steps are:

  Caution: Flashing a new system image deletes all user data. Be certain to first backup any personal data such as photos.

  Download the appropriate system image for your device below, then unzip it to a safe directory.
  Connect your device to your computer over USB.
  Start the device in fastboot mode with one of the following methods:

  Using the adb tool: With the device powered on, execute:

adb reboot bootloader

  Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device.
  For example, to put a Nexus 5 ("hammerhead") into fastboot mode, press
  and hold Volume Up + Volume Down + Power as the device begins booting
  up.

  If necessary, unlock the device's bootloader by running:

fastboot oem unlock

  The target device will show you a confirmation screen. (This erases all data on the target device.)
  Open a terminal and navigate to the unzipped system image directory.
  Execute the flash-all script. This script installs the necessary bootloader, baseband firmware(s), and operating system.

If you are using Windows, you will need third-party software to extract the .tgz archive, because Windows does not support it natively. 7zip is a free (and popular) option.


Issues in rooting Galaxy Note2 GT N7100 I tried to root my Galaxy Note 2 GT N7100 using the following link

"Obtaining IP address" when connecting to WiFi My phone is suddenly stuck at "Obtaining IP address" when trying to connect to a WiFi. I've tried rebooting, deleting and re-adding the WiFi networks, restarting the router (all other devices connected to the router work fine), to no avail.

I'm running Android 7.0. I'd like to avoid a factory reset, so if anyone has an idea what else I could try, I'd appreciate it.

Beginning with with Marshmallow (possibly Lollipop, I was on it for such a short time I can't remember), there is an option in Settings,  Backup & Reset called "Network Settings Reset" described here. This will reset all network settings only in the device, leaving other data intact. Note that all your WiFi passwords and any security certificates will be removed as well, but this will often correct the error you describe.


How does Package Disabler app work? There are two apps that can disable system apps (bloatware) from Samsung and LG devices. Those do not need root or any special permission. Can anyone explain how this works?

There is a difference between disabling and removing bloatwares. Disabling can be done without root, but removing them can be done with root only.

The app for LG that you mentioned changes device ownership permissions. It asks you to make itself the device owner. Quoting this site,

  A Device Owner is an application that runs as a device administrator on your Android 5.0+ device. The Device Owner app can use the programming methods in the DevicePolicyManager class to take control of the configuration, security and other applications on the device. A device can have only one Device Owner. No other applications can utilize the methods in that class to control the device.

As a device owner, the app can modify the partitions that cannot be otherwise accessed without root. Basically you can consider this a restricted root access (restricted because root permissions have many more privileges compared to device ownership).

Remember that making any app a device owner is kind of playing with your phone's security, so don't do that unless you trust the app fully. In root, you have an option to deny root access. Here, you won't even know what the app is doing under cover, and it might be late before you actually remove it.


Why am I unable to install some apps? I own an HTC Salsa with Android 2.3.3 (Gingerbread).

The problem is that I can't download apps like Subway Surfers, Temple Run, Candy Crush, etc. The market reports, "your device is incompatible".

Does it mean hardware requirements?

Is there any way I can upgrade my phone to play the above popular games?

Update:

Very useful information from Mr. Buster. But since there is an update on GOOGLE play now, which doesn't allow you to see the incompatible information.

Screenshots (click images for larger variants)

It could mean that your phone does not meet either software or hardware requirements, or both.  You could probably spoof the identity of your phone (so that it could be recognized as Samsung Galaxy S4 for example, instead of HTC Salsa), but you can't expect the app to work properly in this case.

So, I would suggest to get an updated / higher-end phone instead.

UPDATE 2013-10-30: If you're really looking into spoofing the model of your phone, check out Market Helper (needs root).


How does the Orxify app do what not even the official TOR client for Android can? I was looking for TOR in the Play store a while ago & did not find anything but then today I see that the official TOR site has Orbot for Android but apparently it cannot protect you unless you use apps configured to use Orbot & since I dislike messing with port settings etc. I kept searching to find an app called Orxy with a plugin called Orxify which claims to use the TOR network to anonymize all your Android traffic without any configuring.  Now is that even possible?  Or is it a false claim?  I see no real reviews on the web on Orxify and it seems they changed their name from Anonify...why change it unless they are trying to hide something?  Anybody know of this app and the validity of it's claims?

OS: 4.1
S3

Orbot uses iptables to proxy all apps through Tor, which requires root access.

According to the description of Orxify it uses Android's native VPN mode to proxy all apps through Tor.

Apps that use the built-in Android VPN interface do not require root access. This is the primary advantage of Orxify over Orbot.

On Android 4.0 and above apps can create a native VPN connection without root access to send and receive all network traffic. In this case the Orxify app creates a VPN connection to Tor and routes the internet traffic through the VPN. This can be identified by the key icon in the status bar.

I have not used or tested this app and this explanation is based solely on my knowledge of Tor, VPNs, and the Orxify app Play Store description.


No LTE on samsung s4 mini? I am using a Samsung S4 Mini Model GT-l9195 with Lineage OS 14.1. I used the LTE Image to install LOS. But actually, I am not sure if my phone is able to use LTE. Because there was also a non-LTE version available for LOS, I wonder if there are Samsung S4 phones that don't have LTE built in?

The problem is, I have never seen the LTE sing with the mobile data icon yet, but I am also not using Internet very much on the phone.

As you already know, LineageOS explicitly offers different ROMs for the 3 variants: serrano3gxx (GT-I9190, 3G single-SIM), serranodsdd (GT-I9192, 3G dual-SIM) and serranoltexx (GT-I9195, LTE single-SIM).

The assert checks embedded within the packages will prevent them from being flashed on the wrong variant of device, but this is given that you installed the correct recovery for your variant as well (for which there are no similar assert checks).

With the correct ROM and recovery, if you're still not getting LTE, you should try forcing LTE in Settings. Also be aware that the device itself is a rather early LTE device and as such has very limited LTE band support; PhoneDB shows support for only LTE B3/B7/B20. If your carrier doesn't use any of these bands then naturally you won't get LTE whatsoever.


How to remove soft navigation keys in Xperia without affecting Dialer's call button? I am using Micromax A310 running a custom rom (Sony Xperia).

Whenever I try to remove the soft navigation keys by editing build.prop, the soft nav keys are removed successfully, but my dialler's call key also disappears. The only option remain is to switch to some third party dialler, which I don't prefer.

Please provide some pointers on how to remove the soft nav keys without affecting the stock dialler's call button.

Try hiding the soft keys using Gravity Box, a module for the Xposed framework. Gravity box will let you tweak parts of Android without the need for a custom ROM. There are 3 different versions of Gravity Box for 3 different versions of Android (JB, KK and LP). Link for framework: Xposed. Link to modules: Modules. You can then search for the module you want.


Does Google have a record of my fingerprints from the Android devices? My phone has a fingerprint scanner. I notice on the Google Play Store, it has the option to verify your identity with a fingerprint scan instead of typing in the password when making a purchase.

Does this mean Google has a record of your fingerprints? When is this record made, when you first enable the screen lock with your fingerprint?

No, your fingerprint data never leaves your device.

  Your fingerprint data is stored securely and never leaves your Pixel or Nexus phone. Your fingerprint data isn't shared with Google or any apps on your device. Apps are notified only whether your fingerprint was verified.

Source

Source is from Nexus/Pixel support pages hence why it mentions them specifically. The same should apply for other devices however)


Why do some Android phones have two microphones instead of one? Some phones such as the Samsung Galaxy SIII have two microphones, one next to the user's mouth which as is the case with most mobile phones, but also a second microphone next to the user's ear. Other models such as the Samsung Galaxy S Plus only have one microphone.

What are the advantages of having two microphones on a mobile phone device?

Thanks.

The second microphone is used for noise cancelling. The phone uses it to listen to the external environment (not including your voice), so that it can filter that out from the sounds it hears using the main microphone. That way, it can reduce the amount of noise that comes with your voice, and make your call more audible to the other party.


Dropbox app not installed, but there is log activity in /data/system/dropbox I don't have Dropbox app installed nor DropBox account, but whilst checking log files I've found that there is a /data/system/dropbox directory with log files from, I think, the last time I rebooted my phone.

Why might this present? Is it possibly symptomatic of some kind of malware?

/data/system/dropbox is not part of the cloud storage provider "Dropbox". It is part of the Android OS DropBoxManager (not related at all to "Dropbox", just happen to have the same name).

This puts data from application crashes and kernel logs and such in this log directory. I know the market app uses this directory (See #4) as well, probably to report application crashes.

You could probably remove the data in this directory, but do not delete the directory and you may see logcat errors from parts of the OS/Apps looking for specific files in this directory.

I deleted everything from this folder and rebooted my device afterward, I had no issues with any applications, and it actually freed up some space on the device.


How come some apps won't download from Market? I have a rather odd thing happening to three apps in the Market, all free. I tried to install Google Maps and Angry Birds Seasons from the market, but the downloads or installations failed and now I can't download them at all. They both show up under My Apps but rather than the Update or Installed statuses that all other apps in My Apps show, these two show FREE. When I try to install them all goes normally until the message displays saying the download is happening, but it doesn't. The downloading icon appears in the status bar for the briefest moment before disappearing again.

I have Aldiko Book Reader installed and indicating that there is an update available. I believe that the download or install failed when I first tried to update and now the behaviour is the same as described above. I try to update but the download doesn't happen.

I have successfully updated and installed other apps in the meantime. For now it's only those three that are stuck. The initial cause of download/install failure may have been lack of memory but there should be enough memory available now.

I am using an HTC Desire running CyanogenMod-7.0.0-RC2 (Gingerbread 2.3.3). Anyone have any ideas on how to resolve this problem? I've looked at the Market in application management but the clear cache and clear data options are not available.

simple2ext (as described here: http://forum.cyanogenmod.com/topic/20328-solution-to-unable-to-download-big-apps-from-the-market/ ) did the job for me. I am also running CM 7.0.3 and had problems with downloading big apps from market. Sometimes it helped clearing the dalvik cache but not always.


Export Chrome history in android Is there a way to export the entire browser history from Chrome under Android, in any file format (csv, xml, whatever)?

I have Chrome 42.0.2311.111 under Android 4.2.2.

This may be more than a year late to this question, but...

You can use Google Takeout to download a json file of your Android Chrome history.

You can also download your bookmarks, along with a lot of other Google data.


Change default clock app in Samsung Galaxy Note 9 My previous phone was Nexus 5 and I changed to a Samsung Galaxy Note 9. I'm trying to customize most of the things that I used to be the same as Note 5.

What I liked from Nexus 5 it was notifications for upcoming alarm clock which is missing in Note 9.

I tried to install Google Clock and it works as on a Nexus 5. What I am not able to solve is how to set Google Clock the default app in Note 9. I have noticed that I can't uninstall or even disable the Clock app which comes with Note 9.

I want do do this because I want that Google Assistant to use Google Clock to set alarms and not the default Clock.

Enable developer options and ADB on your phone, and get platform-tools for your OS. Then run:

adb shell
pm list packages | grep [whatever the app name is]
pm hide [name of package]

Alternatively pm uninstall -k --user 0 [name of package] to remove it completely.

Understanding RAM, SD Card and Device Memory of an smartphone I have an Android smartphone and would like to understand what is the difference between RAM, SD Card and Device Memory.
When I check Memory Usage of my smartphone, I see those components:
RAM: 174 used  and  52 MB free
On SD Card: 492 MB used   and  3.16GB free
Device Memory: 143 MB used  and  47 MB free
I understand that "SD Card" is some external memory that you put in the Smartphone.  But how do I understand RAM and Device Memory?

RAM - Random Accessed Memory - When running an application on your phone, the application is loaded from your device memory into the RAM, just like on a computer, the main purpose for this is access speed is far greater in RAM. You can clear the apps that is in the RAM on your phone depending on your smartphone (Samsung for example hold home button down and click ram manager > clear RAM - this will clear what's in RAM however most background apps will automatically be loaded back into the RAM hence the free space decreasing straight away
As you mentioned SD Card is a external memory card which you can switch and swap with a variety of different sizes if needed
Device Memory is your phones built in memory, just like SD Card has memory however this one cannot be swapped or taken out of the phone. It will hold all of your phones files that make it work, just like a PC, as standard you cannot edit these files as they are read only, however through rooting your phone you may access these files and change if needed.

These files as mentioned take up space on your smartphone, so you may have a 16GB device memory or Device Storage, but you could actually only have 15GB free (for example not exact) to use as 1GB is used for the files I mentioned above

Hope this clear it up for you, and I'll happily provide links for further reading for you if needed

Addition Note:

Modern Android phones (4.0+) use an "emulated SD card" for their internal memory. Which means that your phone tricks the OS into seeing the internal memory as an SD card, which can cause some confusion as to the difference between SD memory and internal memory.


How do I turn off push notifications in my Vivo Y53? Whenever my screen is on, and I am connected to network, my Whatsapp messages come directly in the middle of whatever I am doing, which disconnects me and makes me lose all my work. Any solution?

Open WhatsApp.
Tap on three dots on top-right corner of WhatsApp and Select Settings.
Goto Notifications.

Under Message Notifications, there is an option called popup notification. It have several sub options which is easy to identify by its name itself.

No popup: never pop-up on any screen
Only when screen on
Only when screen off
Always show popup.
Also set the same for Group notifications.

Note : If you wish reset to default, tap on three dots on top-right corner while inside Notifications page, which have option to reset notification settings.


how to block an OS app popup? Something on my smartphone sends a message once a day, sometimes I see a tiny fast dark background popup on the bottom saying it is doing so.

Such application seems related to the SIM card, as the popup I receive is from my cell phone provider/carrier/operator.

One second later I receive this:

The app name is "Serviços TIM".
That app package name is "com.android.stk" (I found that using Brevent).
It is an OS App.
It has the exactly same version of "SIM ToolKit" (I guess .stk means that), but at apps list it is in an independent entry with it's own options.

The real huge problem is that, when that popup shows and the screen is locked and remains like that for 8h+, the screen WILL NOT TURN OFF and will spend my battery from 100% to 40% or less and I may depend on having the battery at that time! :(. I usually let it out of the charger, and without that popup it would only spend about 5-10% of the battery.

My smartphone J7 is not rooted, I wonder if that would be the only option?

update:

This other app I think is the culprit from sending the message. It already had SMS disabled but not the phone permission! (I have other app to let me read/send SMS btw)

also the SIM toolkit, I force stop it (and disabled all notifications now 2019):

Final result is: none of these actions above worked, the popup still happens :(

I managed to minimize the problem by using the "do not disturb" feature.
By "minimize" I mean that if I am using the phone the popup will still show up, otherwise it wont mess it's battery (neither show up).
I can allow all exceptions least "reminders" apparently.
Obs.: "do not disturb" is not 100%, I think about 10% of the times it will still allow that abusive popup to keep the screen ON for many hours!

The simToolkit app package "com.android.stk" (which I found out using Brevent), is called "Serviços TIM" and seems to be a mirroed/dup (???) package from the default simToolkit.

My next step (as soon that popup annoys me enough) is to try to uninstall that package by using this tip by @Izzy, thx!

New Google Maps - how to launch quickly navigation Recently released Google Maps doesn't have a standalone app for Navigation which was quick to use - only one tap and voice recognition to start. It takes at least four taps in new Maps to navigate, which is not good to operate while driving. Google Now is not on devices with ICS and below (still majority).

How to start navigation quickly by one tap in current Google Maps? (Google Now is not supported)

Observed on: Google Maps version: 7.02 (700021001), Android ICS 4.0.4, Sony Xperia Active

Previous standalone app on left started navigation immediately after speaking the destination.
New Maps app on right takes 4 taps to small nav icon, edit, mike, start and doesn't show alternatives if voice recognition is poor.

Solution for english is to use Voice Commands. Tap on a mike of a Google Search widget and say „navigate to ‚desired destination‘“.

In other languages you can find a voice assistant like Antelli for Czech who can launch the navigation for you the same way but in your language. (Set it to listen immediately after launch.)

Or with English UI language you can say the command phonetically in your language set for Speech recognition (at least on Android 4.4). If you tell it well so the recognition writes the english word, the voice command will work.


Stuck on Boot Animation Recently I installed MIUI v5 rom on my smartphone.

When I rebooted my smartphone it got stuck on the MI Boot Animation Logo.

What is the problem?

Please Help me.

It is stucked in boot-loop and maybe soft bricked. Its not bricked but can be soft bricked. I had also suffered this problem two times. Dont fear it will not damage any of your hardware function. It only happens if
1. The ROM you flashed doesn't matched with your phone.
2. Gapps has not been installed correctly.

You can solve this problem. Try turning off your phone and after turning on immedietly press the volume up and power button simultaneously. It could be different because different companies have different methods of booting into recovery. If you succeed in it then go ahead and if you fail then try other button combinations. After booting into recovery, navigate to wipe data section by using the volume keys. Then clear your cache partition. After doing this, get your default ROM from any website. I am sure that one or more websites will surely contain  it. AFTER DOWNLOADING IT INSTALL THE ROM. Then clear the dalvik cache and cache. Now, just reboot. Your problem will be solved.If any problem, please comment.


How to switch users without sleep? I have a new 2013 Nexus tablet running Android 4.4.2. I like that it supports multiple user profiles, but the only way I have found to switch profiles is to put the tablet to sleep by pushing the power button or closing the case.

Surely there is a more direct way to reach the login screen?

I have a Nexus 7 V2 and when you bring down the notification area there is a buton with you username on it and the picture you chose. When you click that button, it will bring you to the log in screen where you can switch users. Doing it this way does not end your session.


Want to recover internal data of my phone from cwm-based recovery Whenever I switch my phone on it always shows the name of rom installed, but after that my phone does not get on. I want to recover its internal data .I don't know what to do with cwm-based recovery. Can I retrieve whatsapp chats too?

Ideally you can retrieve nearly everything under CWM via ADB. Use adb shell to explore file structure and adb pull to pull what you want to PC.

However, 1) finding what you want to achieve can be painful, since you need to be familiar with Android filesystem structure, and ADB command line isn't friendly either; 2) even if you managed to find WhatsApp's data, you might not be able to make out what file(s) correspond to chats, and have to do a whole-folder backup, which then means restoring will be a pain (setting permissions and owners).

Retrieving contacts, SMS and simple game saves shouldn't be a problem though, as these usually are stored in one or two files. I've always backed up my savegames in a similar manner. Internal storage is also easy since you know that file structure well.


Change path to store YouTube offline videos in external memory Is it possible to change YouTube's offline video path to an external memory path? I have less internal memory in my phone.

Is it possible to change YouTube's offline video path to an external

This is currently not supported using official YouTube App.

The location for those offline videos is something similar to below:

  Internal

And more so, YouTube controls access to the offline file.

The permission is controlled on their server per account basis, to access those downloaded files.

Epic 4g Touch: Choose to route calls through Google Talk or Sprint A friend of mine just got the Epic 4g Touch (a.k.a. the Sprint version of the Samsung Galaxy s2).  He has installed the Google Voice app on all of his previous Android devices and there has always been an option somewhere to choose whether outgoing calls are routed through Sprint or Google.  This also changes which of his numbers shows up.  However, on his new phone, all calls come from his Google voice number and neither of us can find where to change it.

Is this a new "feature" intended to simplify the program?  Is it some restriction that the Sprint-branded software creates?  Or are we missing something?

He had other problems so he has now switched Google Voice to use his Sprint number.

The next execution of this filetype will present the dialog for your preference again.


My phone uses excessive data 0 I have a sansung s7.  It is gobbling up data.  I've disabled as many programs as i dare from running in the background but no help.  Is there anything i can do about it?

That's not good to hear! If your Samsung S7 Edge is rooted then I would suggest running an application such as AFWall+ and setting custom rules to block applications communicating to web-servers etc.

You did not mention how much data you have to play with, but you could go ahead and install an application such as 3G Watchdog to view what applications are using an excessive amount of data. (This can also be viewed in Settings --> Data)

I would suggest you ensure your accounts are not set to sync frequently, and that apps are not updating over 4G.

Lastly if that all does not help, here are some good forums:

Android Authority - Android OS destroying my Data!

Samsung Forum - OS Application using extensive data

Reddit - S7 Edge using heaps of data

All the best.


Can't uninstall an app in android which is showing ads frequently An app is showing ads frequently on my device. I can't find it in the app collection. I also tried Settings -> Device Administration but didn't get it there. Then I looked for it in Xender (app like ShareIt) and got it there . Its name is Shuffle but can't uninstall it even from there.

I had a similar same problem and solved it this way:

Go to Settings → Device Manager → uncheck unknown app
Go to Setting → Apps → uninstall the first unnamed app from the list

If you don't trust the app you could also uninstall it. Some root apps are flagged as malware (when they are not), but there are also real viruses for Android.


MIUI 7/8 has no way to disable the global Google Spell Check I am the happy owner of a brand new Xiaomi Redmi 3 Prime. It comes with the MIUI 7, and there is a free upgrade to MIUI 8 via the built-in upgrade software.

My only complaint, so far, is that it comes with a utterly annoying spell checker that applies globally to all text inputs, and has no user-friendly way to disable it, as you'll see in the following link. As I found out, this is a problem in the MIUI system. I've tried all the solutions from this thread, but to no avail:

Trying to set the spell_checker_enabled to 0 requires su, and it says su couldn't be found, either from Terminator Emulator for Android and from ADB remote shell.

Are you sure you enabled USB debugging on your phone? Is your phone listed when you enter "adb devices" in cmd? When you connect your phone to your PC, your phone should ask for a confirmation to start USB debugging.

The problem I had with these instructions was that my phone didn't actually connect to my PC, so ADB did not recognize the device.

After installing PDA-net on my PC, that issue was resolved. It installs the correct drivers.

Also make sure that in the USB debugging menu on your phone, you have enabled "USB debugging (security settings)" (you'll need a Mi account).

Then, enter adb shell, and settings put secure spell_checker_enabled 0. That should do it.

Complete instructions

Enable developer options on your phone (search for it in the settings app)
Enable USB debugging on your phone in the settings app
(This might not be required) Enable "USB debugging (security settings)" in the same menu.
Install ADB on your PC (use your favorite search engine to look up "ADB, Fastboot and Drivers - 15 seconds ADB Installer". I'm not allowed to post more than 3 URLs here)
Open a command prompt (cmd) and type cd [folder path where adb was installed].
Connect your phone through USB. Confirm USB debugging on your phone. If you don't get the confirmation window, download and install PDA-net on your PC.
Enter adb shell.
Enter settings put secure spell_checker_enabled 0. Done. Don't forget to disable USB debugging after you're done.


Chinese songs don't show up in Apollo library I have some Chinese songs on my LG Optimus G, which I copied to my music folder along with the rest of the songs. All songs show up in Apollo (Cyanogenmod's standard player), but not the Chinese ones.

I have tried changing the filenames to western alphabet. I have put them in a folder with a name in western alphabet. I have refreshed the media library. I have rebooted. I have deleted the data from Apollo. Yet to no avail. The only thing I've not changed is the MP3 Tag which contains Chinese characters, but that really shouldn't be a problem. I can open each individual song with Apollo from within a file manager, and they play and their MP3 Tag information shows.

The songs played perfectly before I made the move to Cyanogenmod.

How can I make them show up in the library?

I am using CM10.1 with my S2. I have Chinese songs (with Chinese text), and can play them on Apollo.

Your player probably can't see the files. Try to re-scan them using the Rescan SD Card app.


Microsoft Exchange bandwidth out of control? Yesterday afternoon I synced my Galaxy S II with Microsoft Exchange and my multinational corporation's exchange server. Mail settings were to push at all times.

Over night my phone drained its battery completely and rang up 550MB in mobile upload charges via Exchange. I'm certain it was exchange because I have a traffic monitor tool and that particular email client is only holding my exchange account.

This was, to understate, surprising.

Is this normal behavior for Exchange? I only received 8 emails over night, none of which had any attachments to speak of.

Well I finally figured this out, after racking up 800MB of upload and 3.5MB of download with my Exchange Email over 2 days... I had tried to send someone an 8MB PDF and it never sent successfully... so it tried again, and again, and again, and again.

The email was stuck in my outbox and couldn't be deleted. I'd get "server error" messages (DERP!). The solution was to de-couple the device from Exchange, completely removing that account, thereby deleting the message, and then re-registering the device.

Now all is as it should be...

Long story short -- keep an eye on your outbox!


Add rotation toggle to powerbutton menu? Is there any way (short of reflashing to a totally new ROM) to add a "toggle auto-rotate" or "toggle portrait/landscape" option to the menu that comes up when you press and hold the power button?

I'm endlessly fighting with auto-rotation. For whatever reason, every Android device I've owned ends up being over-eager to rotate, but stubbornly resistant to rotating BACK, even when my gestures should be making it completely obvious that I didn't want it to rotate. However, every time I disable auto-rotation, I end up finding myself in a position where I have to rotate to landscape for something, and have to kill even more time trying to re-enable it.

For what it's worth, I have both a Galaxy S3 and a Xoom (wi-fi) (S3 running ICS, Xoom running JB).

In the more recent updates to the Galaxy S III (at least Android 4.1.2) you can modify the notification panel at the top of the notifications screens that you get when you drag from the status bar. Open settings, 'Display' (under 'Device' heading) then in the 'General' heading choose 'Notification panel'.

Here you should be able to choose which Quick setting buttons you want to appear and one of them is the toggle for 'Screen rotation'.


Dashboard/Home Screen icons take up to 10 seconds to load after pressing the Home button I have an issue where the Home Screen (dashboard?) icons can take over 10 seconds to load when I press the home key. After this happens once, the icons will stay there if I open a program and then press the home key again. But, after some time has passed, I'll see this issue again.

Phone restart does not fix this issue. I don't have a lot of Services running and I keep things tidy with Advanced Task Killer.

This question looks similar, but that user's icons never load. Mine will always load, it just takes way too long.

Any thoughts are welcome.

Phone: Motorola Droid; Android 2.2.1; No Root/Mod
Apps: 1 Widget; 27 total icons
Modes: Normal; Desk Charger Mode (whatever that's called)

EDIT:

I uninstalled my Task Killer and a couple other apps that I don't use anymore. The problem isn't as severe, but still occurs. I will try removing the 1 widget I have and perhaps install an alternate launcher.

I have the same phone and pretty much the same issue(s).

First of all, you shouldn't be using a task killer. It's unnecessary and counter productive. (See this question and this other question.)

One thing that will help is using a Home Screen replacement. There are several, but I've been using Zeam. While it doesn't remove the homescreen redraw delay completely, it's much better than without it.

Another thing that will help is reducing or eliminating the number of widgets you're using.


Phone reboots when I connect it to my pc via usb I have a Medion P5015 and I've tried rooting it with Kingroot and Kingoroot together with the pc and android versions but to no avail. Now when I try to connect my phone to my pc with the provided data cable the screen freezes as soon as I plug it in. Soft buttons hard buttons do nothing after a few seconds it reboots to the boot screen but goes to a black screen and goes back to the boot screen and goes on. When I unplug it during this stage it cuts off then I have to manually power it on with the power button, quite absurd if you ask me.

I find that Rooting and such causes unforeseen problems. I am trying to learn to keep everything stock and update when they are available. It is very hard sometimes to resist the temptation.But usually there are negative results down the road. I would rest my phone to factory by going to >Settings>Backup & reset>Factory data reset>Reset phone. It will pop up a confirmation click yes and the phone will then reboot and continue the Reset from recovery mode.


Attempting to brute force Android security pattern through TWRP via adb Yesterday I somehow forgot the Android security pattern on my phone. Due to muscle memory I sort of know what it was, but can't figure out the true pattern. Therefore I'm attempting to brute force it to allow me to unlock the phone again.

Decrypt with pattern
Since I've TWRP recovery installed, I'm able to use the twrp decrypt 'passphrase' command for decryption attempts. I'm using a 4x4 pattern (OnePlus5, LineageOS, Android 8.1, TWRP clockworkx 3.2.3-1) for which each dot in the grid translates to a different character, you should concatenate to build your passphrase. I believe the 4x4 grid looks like this:

1   2   3   4
5   6   7   8
9   :   ;   <
=   >   ?   @

Having a line pattern from the top left to the bottom right would give a passphrase of 16;@, allowing you to decrypt your phone in TWRP using adb shell twrp decrypt '16;@'. (via)

Brute force attempt
Through this method I've attempted all possible patterns I believe could be it, but I didn't succeed decrypting it. The command always returns Attempting to decrypt data partition via command line. to stdout, and nothing else. I'm rapidly attempting each pattern one after the other with no delay, detecting whether any command output differs from the expected output (which hasn't happened yet).

Questions
Because I didn't succeed yet, I'm wondering if my implementation is correct. I don't have a phone to test with, so I have a few questions:

Does the twrp decrypt command output something else when decryption succeeds?
Does successfully decrypting create a block device at /dev/block/dm-0, which I can probe for?
Should I wait a few seconds after each attempt before probing for success?
Is there some sort of hidden timeout (required to wait 30 seconds after attempt)?
Is there another method I can use to probe for success?

Brute force tool
I did build the following tool for this brute force attempt, if that's relevant for what implementation I've used: apbf

I don't understand what is wrong with this implementation. It does not seems to properly decrypt the phone, making me wonder if the key could be corrupted.

I'm currently rebooting recovery after reach attempt, but that takes a lot of time for 1400 possible patterns. I'd like to be sure the attempt isn't useless.

Since I do know the approximate pattern length, am certain only the two right columns are used, and know that the dots in the pattern never have a distance greater than 1, I can greatly reduce the pattern search space and limit the possibilities.

Encryption is enabled on the phone, I believe it's file-based. When in TWRP, the /data/data and /sdcard directory seems to list encrypted file names.

After a while I figured out what the problem was, with a freshly flashed phone. Here I'll be answering my own question.

  Does the twrp decrypt command output something else when decryption succeeds?

Yes, it outputs something like:

Attempting to decrypt data partition via command line.
Data successfully decrypted
Updating partition details...
...done

  Does successfully decrypting create a block device at /dev/block/dm-0, which I can probe for?

No.

  Should I wait a few seconds after each attempt before probing for success?

-

  Is there some sort of hidden timeout (required to wait 30 seconds after attempt)?

Yes, very important! About 10 seconds. Consecutive attempts within that time frame fail with no warning whatsoever.

  Is there another method I can use to probe for success?

-

So, consecutive attempts to invoke twrp decrypt must have at least 10 seconds between them or else they will fail. So, the only thing that was wrong with the developed tool, is that I didn't implement this timeout.


How to restore deleted pictures from LG K8? I accidentally deleted some pics of my daughters that was sent in a txt. I found some recovery apps to get them back but my phone has to be rooted.

How do I root my phone and what does it mean?

You will not need root access if the device runs android 5.0 or above, A photo recovery software is able to recover photos easily without root due to the new changes in Android 5.0 and above, It's still not clear why Android has left this out of the root only features but it's still handy.

The first thing to remember with data recovery is that deleted files are not actually deleted but rather marked as replaceable files ready for new data to replace it, this means you should not to add any new data to the device or it will overwrite the deleted files, so if you fill up the device with more photos, all the old ones will be non repairable ( unless you have software that is powerful enough ) .. Some people say it's possible to repair a file that has been overwritten 7 to 36 times but i don't believe that..

Anyway, the first thing you should try is DiskDigger
This link is to their no root version Photo Recovery

A tip for using disk digger :   Sometimes changing the default storage path in settings > storage will allow DiskDigger to scan the SD Card as the internal storage. It's sometimes helpful to reverse the default storage device between scans if you couldn't find the files you're looking for


How can I share the internet connection of my HTC Wildfire ( Android 2.2 ) via  Bluetooth or USB? I have HTC Wildfire and has Android 2.2 installed on it.

I have internet (GPRS,3G) on mobile. I want to share to my computer as windows XP.

Tried to figure out it first on other questions but didn't found the answer.

How could I share mobiles internet on XP PC ? (Please PC doesn't have wi-fi as its PC. May be some way to share via bluetooth OR USB)

Thanks,

For USB teathering i know only two options that (in my experience) works well:

AziLink - The hard but free way

EasyTeather - The easy but non-free way


Are security patches only applied to the latest Android version? I've got a Pixel phone from Google, but it really doesn't matter, I guess the question would apply to any AOSP-based device. They state that they provide 3 years of version updates and security patches.
I've got an update notification on my phone that it's ready to update to the next Android version (11), but the point is that I don't want to switch, I want to stay on my beloved old version that I'm used to, yet still I want to get security patches to keep my phone safe and bug-free. When looking at Android security bulletin page I see a list of bugfixes and the Android versions they apply to, and some of them span as far as 4 versions back, which practically means the manufacturer is theoretically able to release a patch for my Android version. Thus, I'd like to understand:
What's the Android release lifecycle when it comes to pushing new Android versions and releasing security patches? What role does Google Play system update play in this?
My current situation: Android 10, security patch level - Aug 5, Google Play system update - Sep 1. When clicking on Pixel security bulletin link, nowhere is mentioned that the security patch would apply specifically to version 10 or 11, it just lists the bugfixes.
Does this mean that it's assumed the user would be running the latest Android version, and the patches are built against that latest version he was supposed to have, and he won't be able to receive those unless he upgrades the Android version?

Google provides security updates for older AOSP major versions, but they do not provide updates for Pixel phones.
You can see this easily in the list of available Firmware images for Pixel devices:
Take for example the Pixel 3a:

The available Android 9 releases are dated from March 2019 to August 2019
The available Android 10 releases are dated from September 2019 to August 2020
The available Android 11 releases are dated from September 2020 to October 2020 (now)

As these are all factory images available for the Pixel 3a you can see that there are no (security) updates for Android 9 based images after Android 10 has been released and the same is true for Android 10 which stops after Android 11 has been released.
The provided images are not OTA updates received by regular bootloader locked devices, but I would assume that Google does provide the same versions as full firmware images and OTA updates.


How to modify /system/priv-app in Android 10? I use ES File Explorer to modify /system/priv-app in the past with root permission given via magisk.

After upgrading to Android 10, ES File Explorer can no longer modify the /system/priv-app giving me an error message saying "operation failed."

What alternatives do I have if I like to modify /system/priv-app?

The output of running set -x; exec >>/sdcard/mount.log 2>&1; id; mount -o rw,remount /system; mount | grep 'on /system '; touch /system/test_file; cat /sys/block/dm-*/dm/name:

uid=0(root) gid=0(root) groups=0(root) context=u:r:magisk:s0
mount: '/system' not in /proc/mounts
touch: '/system/test_file': Read-only file system
vendor-verity

It turns out:

  On some system-as-root (SAR) devices you can no longer mount the system partition as read-write and doing systemless modifications through Magisk is the only way. If you do want to do actual edits of the system, and if it is even possible (from Android 10 it's actually impossible on some devices), you need to mount the root directory, /, as rw and not /system. You can also try editing the partition mirrors that Magisk keeps in /sbin/.magisk/mirror.

So all I needed to do is to:

mount -o rw,remount /

You need to remount the partition as read-write. mount -wo remount / (change / to /system if you don't have system root enabled in my app). It should work then, though if not you probably have a read only filesystem like EROFS


How to disable flashlight in lock screen in Lollipop on Xcover 3? Since upgrading my Samsung Galaxy Xcover 3 phone to Android 5.1 Lollipop, I've noticed that the flashlight keeps getting turned on in my pocket. Apparently, pressing the "Xcover button" on the side of the phone will now toggle the flashlight on and off even in the lock screen.

I've tried to find some way to turn this behavior off, but I'm not seeing anything in the settings that would look promising. My attemps to Google for a solution just yield instructions for enabling flaslight access from the lock screen on versions prior to Lollipop.

Short of getting a more robust case for my phone, how can I keep my pockets from shining in the dark?

Today my girlfriend's father ask me how to solve it.
I've just written an lightweight app (7kB) which does nothing at all.

Download it from here and set as your XCover button app :)


How can I restore remembered wifi networks and saved wifi passwords? I know this question has been asked before and I have searched google for far too long to not have an answer.

So the situation is

I have done a data wipe and a clean install.
During the setup process I did not choose to restore anything.
After the installation I went to Settings > Backup & reset and enabled Automatic restore.
Yet no saved wifi networks or passwords were restored.

I cannot find anything related to Network restore under Settings > Google

Android 6.0.1
Gapps 6.0
Nexus 5

When you set up a phone and choose not to restore its previous backups, it creates a new "set" of backup data, independent of your old backups. From now on, your phone will only backup to and restore from this new set.

There's no simple way to make it switch back to the old set, to restore your old Wi-Fi settings, but my answer on a question about backing up multiple devices explains how a power user can use the bmgr tool to find old sets of backup data and switch to (i.e. restore from) a different set. I'm afraid you'll have to look at the data and use your judgement: there's no one step-by-step solution that will work for every case.


Is there any program to root my device without connecting it to PC? I am looking for an APK software which could be installed on my Android device (Samsung S3 I9300) that root my device without needing to connect the device to PC during root process. Or any other way for rooting without need of connecting to PC. Is there any way?

Framaroot, if you are running 4.2.2 or lower. I don't know about anything for 4.3 and up which works reliably on most devices.


Modern Combat Sandstorm Texture problem on Acer Liquid Metal The game works perfectly except many graphical glitches with textures (mainly those in the background).
any hints?

I have Acer Liquid Metal, official Froyo

You should contact GameLoft.  They officially support the Acer Liquid for that game, and thus should be able to help you (or at least take a bug report).  They don't specify which versions of the Liquid they support, so it could just be that they haven't tested on the Metal.


How to clear the keyboard autocomplete suggestions I need to completely clear the autocomplete words my Sony Ericsson Xperia arc has learned. I used it for entering some random letter combinations (CAPTCHA entries) and now they are part of the autocomplete for some important prefixes. How can this be done? Looked in the settings screen but no luck.

This is positioned high in Google, so I'm gonna paste my solution here. I own a Sonyericsson Xperia Arc S and the Personal Dictionary list was empty.

The way to go was to go into the app listing (all apps), find the Xperia Keyboard service and Clear Data.

It resets every keyboard configuration, but it's how it works.


How do i update the video driver? How do I update the video driver for my Droid 2 Global? I have a custom Cyanogenmod installed but YouTube videos have a green bar, green tint, or are garbled.

By installing a different version of Cyanogenmod. Android is not like Windows, where you have to install each driver separately: all the drivers come integrated in the ROM. Sometimes, with third-party ROMs like Cyanogenmod, they don't quite manage to integrate the drivers properly (because only the manufacturer has all the required information), so you get defects like this one.

If you found the problem in a stable release, release candidate, or beta of Cyanogenmod, you should report it to the maintainers for your phone so they can fix it. If you've been using a nightly snapshot, don't bother, as they are expected to have serious errors and aren't suitable for everyday use.

Upgrade to a newer release if there is one, or perhaps to an older release.


Why is my Samsung Galaxy phone automatically moving read Yahoo email to the spam folder? Why is my Samsung Galaxy phone automatically moving read Yahoo email to the spam folder? This usually happens when there is an attachment.

This is another post that I found on this.  Basically the Samsung phone has it's own spam settings.  http://www.slipstick.com/outlook/moves-email-junk-folder/ describes this, and then explains:

  The solution:

  Go into the E-Mail app (on the phone)
  Press the Menu Key, select Settings, then General Settings
  Select Spam addresses and remove any addresses that should not be in there, such as your corporate domain.


Can I increase the frequency at which location history gets my location? I've recently discovered Google Location History, however my history map is made up of lots of very long straight lines because it doesn't appear to get checkpoint/location information very often.

Is there any way to increase how many times it gets the location in order to get a more accurate view of my movements in a day? I understand that this may reduce battery life.

Thank you.

"Start driving"[1] in Google Maps increases the frequency to 15 seconds per sample. Then send it to background, turn off the screen. It consumes more battery but not much.

[1] since the side menu has been removed, the feature can only be used by adding a shortcut (sometimes called widget) to your home screen.


SD card unexpectedly removed I have a galaxy S3 with a 32gb class10 sd card.

Unfortunately I experience the SD card unexpectedly removed - Preparing SD card phenomenon all the time. The card works ok as long as it is being used: I watch videos, mp3 etc, even on pc.

I tried formatting a couple of times and I also checked on other S3 phone which presented the same problem. I checked a 16 GB class 10 card on my phone which worked ok!

I read somewhere that this is a JB problem and that I should wait for 4.2 (I'm on 4.1.1 now)

Another solution explained that I should root my phone and do this:

  Edit files in the folder /sys/devices/virtual/bd i/179:
  0/read_ahead_kb by pressing and holding the read_ahead_kb then choose
  open in text editor.

  Note: Other phones don't have 179:0.. but is ok 179:8   Replace the
  numbers in it from the default (128KB) to 1024 / 2048 / 4096
  (according to taste max = 4096) and then save and exit.

What are your thoughts? is it JB or the Card?

I should also mention that the removing/rescanning my card is killing my battery very fast.

Sounds like an SD card problem to me. I've experienced similar problems a few times over the course of the years -- a card that has worked ok for some time has started to get "ejected" by itself. Changing the SD card has always solved the problem. .. Hmm. Except once but that phone turned out to be a very problematic case in a number of ways.

So, try out changing the SD card, I would suggest.


Do I need to format my external SD Card? I have a Samsung Galaxy S 5 and will be adding a Class 10, 64 Gig micro SDXC UHS-1 Card. I've seen people refer to formatting an SD card. How do I know if that's necessary in my case?

*Edit: I should have said it's a brand new, unused card.

Not to remain in any doubt, its the best practice to get your card formatted from within your android device.  In setting... storage settings you are going to find the options to do so.


Ads security issue affecting all Android system for a couples of day I have noticed that there is a strange behavior on my Android phone device. and I think it is a global problem.

I have noticed that some Ads appears in the screen in whatever app is opened or on the home screen, with and X to close it. It could appear overlapping any application, and in the middle of the screen but not full screen.

I closed it, and I didn't know what application causing that behavior, but after a while I have noticed that some application are installing them self without any permission from my side. those application are four and appears on the notification bar with  is downloading themself. and the phone is going so slow.

I check the apps manager and I found four strange services I didn't notice them before.

adService
Clain Left
com.android.tools
com.bd.sdk.project

I uninstall them and they return again and again every one or two hours. and in different Wifi network.

I decided to rest my phone to its factory setting. but I still got the same problem.!!!

Dose somebody faced that kind of problem recently? and what solve this problem.
Thanks

it keeps reappearing because you are not removing the problem causing potentially unwanted program. You probably have something from that category and these intruders are not that easy to remove. You uninstall only the feature that annoys you but not the problem itself. Especially since you can see there is not one program appearing.
You should rely on anti-malware tools and remove possible threats, intruders, cyber infections. There is a few available online for free. You can find them on the App Store. Those programs can detect, remove and even block threats later on.
These additional programs come from insecure ads, websites, installations. So you can't see when they were downloaded exactly and the ones on your browser are not the main program that causes problems.


What is nobody@localhost in Google calendar app I seen something strange option in my Google calendar app in my realme mobile.

There is account with name "NOBODY@LOCALHOST" and with the check box option "nobody@localhost"

I didn't seen before in my past mobile

Any solution appreciated?

This mostly appears in Oppo/Realme phones or maybe all phones from China.

Anyway,to remove it,install on your phone iCal from Google Play Store.
Open the app, use it to look at the calendars on your phones, choose nobody@localhost and delete it using iCal. Job done.

Hope this helped.


Wi-Fi Network can not scanned I am having problem with my recently bought SONY XPERIA SL. I have CISCO WAP4410N router, and its SSID cannot be scanned or connected (manually) on my phone, while being on AUTO CHANNEL selection mode. Where as I am using the same network previously for my iPhone and even for different laptops.

While when I change the channel manually to no 10, I am able to access the network.

Anybody can resolve this issue for me?

An helpful app to resolve this might be Wifi Analyzer, it shows the available (and perhaps conflicting) wifi channels and their strength.


Samsung's stock Android app in another phone Okay so here is how it goes. My brother has a Samsung Galaxy j7 and it has some really catchy versions of the normal Android apps like, clock and calculator are very different and good looking though. Now whenever I try to install them in my phone they just crash ( I sent their apks through share-it ) and they don't work.
I just want to ask is there a way I could install them in my phone, maybe edit the check point or copy the code or something else. Am using an Htc, if that helps. I really don't have any programming experience in Android or Java.

Download it off of apk mirror, and it should work. Here's the link
