Please explain this weird response to adb command 127|root@android:/ # find / -iname "aaengine"
find: /proc/19619: No such file or directory

I dont know why I got told about some file I never known about when trying to find aaengine file

Quite easy: find / starts exploring at the file system root (i.e. the very top). So it comes to places you have no access to as normal user, and runs into permission issues. It sees a directory called /proc/19619 and, knowing this is a directory, wants to traverse into it. But it is not permitted to (most likely the permission of that directory is something like drwxr--r--, so everybody can see ("r"ead) it – but only its owner can change into (eXecute)). So your find sees it, but can not dive into it.

As you've been running this command as root, permission problems shouldn't be the issue. But taking a look at the directory in question pops up a different answer: /proc is storing process information. Below this top-level dir, directories are created using the PID of running processes. So /proc/19619 stores information on process 19619. Most likely your find was seeing that directory, and at the same moment that process ended; so when find finally wanted to dive into, it was gone: No such file or directory (not anymore).


How to get my phone to access WIFI channel 13? My phone can't see Wifi 2.4 Channel 13. Why? How can I fix it?

I have an android phone (Moto E4, Android 7.1.1, Not rooted) that was purchased in the US about 12 months ago. Just after purchase,I came to China for a few months, and it worked perfectly on the Wifi here in my home. I had a Chinese sim card. I don't know what channel my home Wifi was working on last year.

In September, I returned to the US and swapped out the sim card for a US carrier. It continued to work perfectly.

I have just now returned to China, and my phone no longer can see the wifi signal in my home. When I look on my PC, it shows that the Wifi is transmitting on channel 13. When I look in my android app "Wifi Analyzer" it shows a blank space for channel 13. (Also, I forgot my Chinese sim card in the US)

Is this a hardware or a software issue? How to fix this?

My phone can now detect ch 13 on 2.4 GHz wifi.

Here's how I did it. I borrowed a local sim card. As soon as the phone booted up, if was able to see the wifi signal. I confirmed that it indeed was on ch 13 with both wifi analyzer and on my pc.

I have since removed the borrowed sim card, and the phone continues to see channel 13. So indeed, as suggested in the comments by @Robert,

  auto detection of the country you are in e.g. via used SIM card

Is the correct answer.


gif image is not working in Gallery in Nexus 5 i have downloaded some  gif images from tumblr.com. but is is not working in my Nexus 5 Gallery (Android 4.4.4).

It's fine in my Samsung Galaxy S4. So, how to display gif image in my Nexus 5?

Any one has any idea.

Not displaying a *.gif image is more-likely related to the application you are trying to view the image with, rather than being device specific.

Take a look on the Google PlayStore for an alternative picture/gallery application. I know of one called "GIF Player" which could be of use in the worst-case scenario.


Risks of removing the stock browser on LineageOS I would like to get rid of the stock browser (org.lineageos.jelly) on my phone that runs LineageOS. Other threads and sites already go into the details of removing pre-installed apps with/without root but I am wondering if there are any risks of removing the browser in particular? For instance, is the Android System WebView implementation in any way tied to the stock browser? (I'd still want to be able to use apps that use WebView.) More generally, is there anything else I'd affect by removing the stock browser?

I ended up going ahead and just removed the Jelly browser – initially manually by using TWRP's file manager and later – since it came back when I updated the system afterwards (duh) – using a handy flashable zip that I got from LOSdiet. So far, so good. Everything seems to work fine.

As for WebView, the Android System WebView entry in the developer settings is still there, so I suppose WebView is not tied to the Jelly.apk. Indeed, the LOSdiet site github.io page as well as the old CyanogenMod "barebones" wiki page indicate that the default (pre-installed) WebView is a separate .apk.


unrecognized message, now all locked out I allowed my nephew to play with my Samsung tab 3 and it is now saying that I have accessed an account without being authorized and is asking for a password that I have never set, what can I do, without doing a factory reset?

That sounds similar to cryptolocker, without the paying to release your device. Try booting in safe mode(look up how, it varies) and taking off what your child used.


Remotely Turn on Location for Lost/Stolen Phone My Samsung Galaxy S7 was lost or stolen tonight at an airport.  I can remotely see that it is at 63% battery power, but I had the google location turned off.  How can I remotely turn on location?  (I did lock the phone because I didn't pw protect it and left a message to call my husband.)

Uhm... As far as I know, there is no possibility to remotely turn on GPS on your lost/stolen phone unfortunately, which is why I always considered this "track my phone" Google feature absolutely useless.


Can a group admin remove the group creator on WhatsApp? Can a group admin remove the group creator on WhatsApp? If i add a person as creator then make them admin.. can they remove me from my own group?

The way WhatsApp works is whenever a group is created by user he is himself an admin by default and can add other people as admins. And all admins have the same privileges so basically, an admin can remove anyone from the group including the creator as simple as that.


Making a custom upgrade ROM Is it possible to make a custom ROM to upgrade the current version of android that is installed on your phone?

For example, making a 5.1 ROM to put on an pretty much unsupported phone that only has 4.4.2.

I've seen many posts on how to port ROMs between devices, or making your own custom ROM, but all of the ones I've seen require you to stay on the same version of android.

I'm just wondering if I can take a stock ROM, or a cm 12.1 rom or something and port it onto my device. (Which is a LGD393 in case that helps).

Firstly . It is possible to make a custom ROM to upgrade the current version of android that is installed on your phone

Secondly you can't port roms of other devices to your phone . But  you can take the stock rom of your device and make some modifications to upgrade the version of android.

For custom rom development refer here.

“There's been a change to your Google account” message and password prompt? I got a message on my device yesterday (2017-02-23):

  "There's been a change to your Google account"

along with a prompt to re-enter my password.

I follow good security practices and have regularly run through the security wizard at myaccount.google.com. I also use two-step verification.

Could someone be using my account or is this a known issue?

It looks like this is a known issue, and Google is on top of it.
From the product forums:

We've gotten reports about some users being signed out of their accounts unexpectedly. We're investigating, but not to worry: there is no indication that this is connected to any phishing or account security threats.
Please try to sign-in again at accounts.google.com and if you cannot remember your password, please use this link (g.co/recover) to recover your password. If you use 2-Step Verification, there may have been a delay in receiving your SMS code. Please try again or use backup codes.

Essentially the same message is currently displayed at the top of the Accounts Help: Can't sign in to your Google Account page.
Also, from @google on Twitter:

How to block/disable WiFiKill effectiveness on WiFi network? I just gave WiFiKill app to someone I know in the region where the college is and I guided him how to get it work. That was before the ending of holiday.

At these days after holiday ended, he monitored that college WiFi network cutting all bandwidth on other connected devices, although they're connected to network. I hear all of them complain about the Internet while he's enjoying full internet bandwidth, which is not fair at all because that internet is only dedicated for college students only, not for citizens of that region.

How to disable this app affecting college WiFi network? What will happen if 2 users using WiFiKill on the same network and each one of them block internet on the other device?

Pretty much.. no. WiFiKill uses ARP poisoning to cause computers on the local network segment to use the wrong MAC address for the router, resulting in all packets being dropped. A second device running WiFiKill would have no visible effect; however, if you could spoof ARP reply packets which have the correct MAC address in them it could be used to mitigate the effects -- maybe. The two devices would be in a race at that point.


How to import a .obf POI file in OsmAnd I created this Data.osm file:

<?xml version='1.0' encoding='UTF-8'?>
<osm version='0.5' generator='GPSBabel-1.4.0'>
  <node id='-1' visible='true' lat='41.890121' lon='12.492265'>
    <tag k='name' v='place01'/>
    <tag k='note' v='place01'/>
    <tag k='tourism' v='museum'/>
  </node>
</osm>

Then I converted it to Data.obf using OsmAndMapCreator.

How to have OsmAnd show this POI on the maps?

1) Copy the .obf file to your OsmAnd folder, for instance /sdcard/osmand.

2) In OsmAnd, enable the "POI > Any" layer.

3) Sometimes it does not work immediately, in such case restart your phone (there might be faster methods but at least restarting works)


Google Play Store on a Samsung Galaxy Ace missing I have a Samsung Galaxy Ace with Android 2.3.4. The phone came with Samsung App Store not the Google market. I would like to install the Google market or Google Play as there is a better selection of apps. However the play.google.com website has no link to download the store. What can I do?

The update is OTA - so if you are scheduled to receive it for your device (which I believe you should have) - you should go to Settings >> About >> System Updates - and check for an update.

You may need to update your device to 2.3.5 to receive the update.


How do I turn off speech search in Jelly Bean? I have a rooted Samsung Galaxy S 2, and last night I updated it to Jelly Bean in hopes that it might solve a few small bugs.

Most everything seems to be working as hoped. However, one new inconvenience has popped up. Before the upgrade, I controlled my MP3 player, Poweramp, by pressing the button attached to the wire of my headphones. One short press to stop and start songs, one long press to advance forward.

After upgrading, whenever I press the button, the phone goes into voice search mode. That is, it turns on the microphone and is waiting for me to say something to search for using the Google search app.

I have tried to look in system settings, and also in the settings for the Google search widget that's on the top of every screen. However, I can't find any way of turning this off.

I want to give priority to Poweramp so that I can control music playback. How do I get voice search to stop getting in the way?

I do not know of a way to disable Google Now intercepting media button presess unless you have a rooted phone, as you did not specify that you did, I am going to assume you don't.

The easiest way to do this would be to disable the Google Voice search app.

Go to your Apps settings menu (System Settings --> Apps).

Slide to the left until you get to the 'All' list, scroll down until you find the app named 'Google Voice Search', click it and click the disable button - now reboot your device.

Edit:

As you have a rooted phone, you could install the Auto starts app from Google play, and use it to disable the 'Media Button Pressed' entry under Google Voice Search.

This is a paid app.

Google Voice Search will not act as if it is not installed onto your device.


Why does my android phone gain battery when I turn it off and on again? When I got my new android phone (ZTE N762), I noticed something. If my phone is about halfway on battery, and I turn it off for a few hours, it will gain battery life when I turn it back on, around 5%-10%. I use this trick whenever I'm low on battery.

Does anyone know why this is?

I doubt very much that your battery is actually gaining energy, what with the conservation of energy and all that.  Instead I imagine that the meter is fairly inaccurate, and is inaccurate in a different way just after you turn on the phone, than when the phone has been running a while.


Phone Screen Blackouts and respond only to Power Key Long Press I have Moto G with Bootloader unlocked and I have installed TWRP Recovery and I was using CM-12 Nightly Build.

The device was working fine but now The device just Blackouts after reboot and I am unable to access any control of device but when I press Power button for couple of seconds, it shows Reboot/power off/Airplane mode option.

I am able to hear caller ringtones and everything seems to be working fine except the screen is completely black.

I just switched off my phone and then reboot in Fastboot Mode using Power + Volume Down key and then chosen recovery.

In recovery mode I choose Wipe and then Format Data then typed Yes and hit Go

This will take some time and the phone will reboot and now it's working fine.

Note : Take backup of data before formatting, you can take backup by connecting phone to your PC via USB and Copying all data on PC.


SSH Tunneling with Android; Not working; I have a rooted Galaxy S4.

I'm trying to establish an SSH tunnel so I can access mysql from my phone.

I've tried using multiple SSH apps to tunnel but I can never get any of my tunnels to work.

I think I'm doing something wrong, I would appreciated help.

Here is the command equivalent of the tunnel I'm trying to setup for mysql access.

ssh -L 1234:[mysql adress]:3306 [my ssh user]@[my domain name].com

Where [mysql adress] is the same address I use in php to connect to,
[my ssh user] is the username I use to login into ssh and ftp,
[my domain name] is the domain name I have and the one I use for ssh and ftp.

After that I would try to connect to mysql by connecting to

[my domain name].com:1234

and it would time out while waiting for response.

I've tried using different tunnels to test, but I can't get any of them to work.

I've tried to tunnel to the website http

ssh -L 1234:127.0.0.1:80 [my ssh user]@[my domain name].com

And it just hangs when I try to load

[my domain name].com:1234

in the browser.

I've also tried to tunnel to the website FTP server

ssh -L 1234:127.0.0.1:21 [my ssh user]@[my domain name].com

And it just hangs at "connecting" when I try to connect to

[my ftp user]@[my domain name].us:1234

with an FTP client.

I've tried using multiple SSH apps.

Can anyone give me any advice?

Once the tunnel is created, you should connect to mysql using localhost:1234 or 127.0.0.1:1234


to identify these services after upg. to andr 10? To all,

please tell me if this is relevant to the forum.

the problem:

I want to identify these services that appear after the upgrade to Android 10, in adjustments -> applications and notifications -> manager of permissions -> storage and other permissions. Some data:

model: Nokia 4,2
this model has the Android One distribution.

I didn't find anything in web search for this one:

QMMI

in the search there appear titles such as "hidden settings" or something related to Xiaomi. the others are, in total:

com.android.carrierconfig
com.qualcomm.qti.workloadclassifier
face

more observations:

the election to uninstall or disable are not available for any these.
until now, only user style titles appeared in permissions, such as Chrome or Foo Service, never something in the style of a kernel module foo.bar.baz

questions / ideas:

Is this how it should be in a valid update of Android from Google?
how to uninstall / to investigate: maybe I can enter a linux terminal? is it possible to create a root user with password, but not to disqualify of Android updates? also, it would be from inside the device: I would not open a server for this purpose intentionally.

Thanks in advance,

Dan

The following observation supports a conclusion that this no more than a quirk of the last system update:

According to this link to an Android package QMMI, it seems that this is created by HMD Global the company that produces Nokia.


Contacts sync in the opposite direction I tried to sync my contacts in my phone (Android 4.0.3), and as a result all my contacts in my phone were changed to the old contacts I had in my google accont on the web. For example. if I had changed a phone number to a new one in my cellular phone before the sync, it changed back to the old number that was on the web.
Can I restore the up-to-date numbers that I lost? What could have gone wrong?

I remember having gone through the same problem years back (on a froyo device). Not sure what caused it, but I fixed it as follows:

Exporting ALL your google contacts to a file (make sure everything is in there)
Remove all contacts from google
Remove all contacts from phone
Import the contacts from the file (exported in (1)) to the PHONE
Sync the contacts
Verify whether the sync worked

After doing this two way sync worked perfectly for me. I can not guarantee that this will work for you, but it may be worth a try. Also, make very sure that the export in (1) is complete (check the contents of the file) - also, export to various file formats for safety.

Unfortunately, the changes you made on the phone will have been overwritten and I do not know of a way to revert that. In the future, if the problem persists, you can disable the sync and do it manually using files - it sucks, but at least you won't lose information.


Kidz-Star tablet that won't save photos onto external sd card My son's Kidzstar tablet doesn't have any option on the camera where to store photos and videos. The tablet is using 4.0.3. The photos and videos are being stored to internal SD card which it says is full and so can't take any more photos or videos. I bought a 16GB Micro SD Card and mounted it but the device will still not allow me to take photos. Also Apps can only be moved from internal memory to internal SD card with no option for external SD card.

What should I do?

There are some options. They all most likely start with making some room first by moving the pictures/videos already present on internal storage/internal SD to the external SD. Then:

use a 3rd party camera app supporting to save on external SD. Most of them do. My personal recommendation (very subjective of course) would be ProCapture Free (and if you like it, go Pro).
Try some "advanced App2SD" app from the playstore, which might be able to move (more) apps to the external card. This might require rooting.
for some devices, there are hacks to "switch" storage locations, i.e. making the device think the external SD card is the internal, and vice versa. They for sure require root.

I would go with the first option. It's the most easy to realize, does not require root, and for sure doesn't have that much potential to "mess things up". You even can make the "new camera app" the default one, or switch back to the stock one anytime.


How do I automate disabling mobile data on lollipop? I have recently changed my Moto G LTE (XT1039) from android 4.x to 5.1.

After the update I have found that Llama - Location Profiles's Toggle mobile data - mobile data off Action fails to disable my mobile data.

After checking out a few alternatives I have found that several automation apps have reviews mentioning a similar situation. For example Data ON-OFF has this review:

  Not working 5.1 motto 4g Used to work on 4.4.4 uninstalled until it gets an update.

How do I automate the toggling of mobile data on/off in Android 5.1?

Or, has there been a change to the android API to remove this functionality?

There appears to be an app/widget on XDA that should do what you are asking.

Link to the thread can be found here -
Link to the app in the play store can be found here

The app is paid and requires root. Hope this helps. =)


How to update Cyangenmod 10.1 to 10.2? I have Cyangenmod 10.1.3 installed on my Xperia Z. When I tried to download Cyangenmod 10.2-20131101 nightly build in my phone's settings, no error but it silently failed after some time. I tried again but the problem persists.

Any idea what went wrong?

Am I supposed to download the zip file, copy it to my phone and boot into recovery mode to do a manual installation?

You should follow these steps:

Download the relevant ZIP file from get.cm
Copy the downloaded ZIP file to your devices storage card
Using an app such as Titanium Backup, do a complete backup of all your installed applications.
Boot into recovery, and follow these steps:

Wipe data (all data)
Install the zip file as usual

Once done, reboot device.
Using the backup app, restore your apps.
Reboot device.

You will now be running the latest version. The data wipe is highly recommended, but your device should still work without it - you must wipe the dalvik cache at the very least however, or you'll get a boot loop.

Important Note

If you use google apps (GApps) then you must make sure you download the version for CM 10.2. If you do not, you may experience compatibility errors.


How to migrate accounts to new Google Authenticator app? I broke my cellphone which had the Google Authenticator app and several other accounts attached to it for two factor authentication like Dropbox, Evernote, AWS, etc. Now I got a new phone and installed the Google Authenticator app on it as per the instructions given here - https://support.google.com/accounts/answer/185834?hl=en#phone

But now in this app I don't see codes for other accounts (Dropbox, Evernote, etc.). Is there a way to get all of them migrated to this new app or I need to recreate them?
Also, if I need to recreate them, how do I do it, because Evernote won't even let me sign in from any device w/o two factor authentication code.
I can use backup codes for some accounts, but I don't have backup codes for all of them?

Please provide some suggestions. Thank you.

This is actually what you have to use backup codes for.
If you can still access your old device and it's rooted you can backup the database and restore it on your new phone.

However, if you can no longer access your old phone and you do not have recovery codes you have to contact their support and sort it out with them.

This is the purpose of two-factor authentication, if the second factor is inaccessible you can no longer access your account. If someone knows your password they can't do anything without your phone aswell.

This is also why services like authy are really sketchy due to the second factor not being offline-only.


Change .pdf-file-icon under Total Commander I have recently installed the Dropbox app and it overwrote the standard pdf-file-icon my file manager was displaying. i don't like the dropbox-pdf-icon and would like to have the previous one back.

  Is this possible w/o uninstalling the Dropbox app?

p.s. I have a rooted device

Total Commander (TC will show the first returned icon for that type. It seems.to be impossible to reorder them by hand. TC calls packageManager.queryIntentActivities to find out which apps are associated with a certain file type. If none of them is marked as a default, TC uses the first one in the mentioned list. But there is no clue (yet) in which order these are returned by Android.

You may also choose your own:

Go to: Main menu - Configure - Internal associations
Add new extension: .pdf
Choose an icon via button in the lower left


I had lost few of my data from my Android phone's memory card I'm using gionee marathon M3 with android 4.4.2. I had purchased Sony Micro sd HC UHS-1 class-10 memory card(Purchased from PayTM) of 32GB.

I had downloaded this card with 15 gb of data using card reader. Then I had taken more videos and songs from my friends device using xender. Later I had also downloaded videos from whatsapp and web. And once I also attached it to pc using data cable and downloaded few photos into it. Finally it have data of 25gb inside it.

After three days, when I go to file manager, I had shown that My card had lost few data from it (Approx 10 gb) and there present other data as it is. The lost data or files became 0 bytes in size automatically.

I had checked for data by connecting memory card by card reader to pc, still lost files are of 0 bytes. I had connected my phone to pc using data cable, still the lost files are of 0 bytes.

Why is this happen? Is there any problem with memory card or with it's class, or with phone or with memory card's size? My phone supports memory card upto 128GB. Please tell me what to do? Should I purchase memory card of 16GB or of 32GB having class 4? And also please tell me about recovering this data(Videos, Pictures)

Please help me with this.

Its most likely a one time issue. No, you don't need to run and buy a new SD card. There is a high chance that the issue was with your phone or a rogue app on it.
Also, always back up your data to prevent a major loss.
Its hard and many times costly to recover data from Flash drive unlike a hard drive. I would suggest you let go and if preferable format the SD card and forget about it.

Its a problem if this happens again anytime soon. Also check your apps to see if you don't have any rogue app or a pirated app.


Prevent automatic redirects in Mobile Firefox for Android How can I turn disable redirects in Firefox for Android?

Here is a solution that works for desktop Firefox:

Prevent automatic redirects in Firefox

Unfortunately the accessibility.blockautorefresh option is not present in Firefox for Android.

As noted in this answer from the same question you linked, you can use network.http.redirection-limit to block redirects. Start by setting it to 0 (instead of 1 as in the linked answer). It will will have the effects of blocking all redirects and even accessing any site.

Then increasing with the value will allow depending on the site to allow redirects (or clicking "Try again" when the redict was blocked).


Clear HTML5 storage in Samsung Internet? I have a problem using Samsung Internet Mobile Browser on my NoteFE running non-rooted Android 8.0.

Some websites (like mega.nz) use - what I suppose - HTML5 to store data/files offline somewhere. To access the downloaded data as file, Samsung Internet then copies the download from the internal storage to a normal file. This looks like a download, but the data is already in some kind of cache. Chrome does the same, also on PC.

Now, it seems like Samsung Internet doesn't delete this background data. However, looking at app details, I see "data" (not "cache"!) growing with each download, filling up my phones memory. It's already a couple of GB in size.

How do I reclaim this space? Only option seems to be to 'clear data', which includes all bookmarks, site info, and what not.

Never mind. I found it:

Menu - Settings - Advanced - Manage website data

This list distinguishes between normal and https, and I failed to find the item as it was saved from a page without https, while the site generally is served with https. So 2 entries, the one was the one with the big size.

Problem solved!

How do I answer phone on Honor 8 when screen is locked? I'm sure it's easy, but I have no idea how to answer my phone when the screen is locked. There is a circle in the middle and a green phone on the left and a red phone on the right. No matter what I press, it rejects the call.

If it's something similar to what I have in the screenshot, then all you have to do is drag the middle circle to the green phone icon. To hang up, drag the middle circle to the red icon.


Can I have a folder (on the home screen) with more than the default amount allowed per folder on the Nexus 5, which is 16? I'm searching a way to make all my games into a single folder. Is there a tweak/app/root command to makes my folders (not storage folders, folders in which you can add shortcuts for apps n' stuff) have, for exemple, multiple pages, kinda like in the IOS system, or a scroll-able folder? Or a way of having a folder in a folder (which would be overkill but hey, it's still a way to enhance the capacity of the folders.)?

I'm using a Nexus 5 running the stock ROM with Android 5.1.1. And I would prefer staying like that, not using Launchers or custom ROMs.

Thanks! ^.^

While there are root apps/extensions such as Xposed GEL Settings that will let you modify all sorts of settings in the Google Now Launcher (formerly Google Experience Launcher), folder capacity limits is not one of them. Google's aware that this bothers people and it's a confirmed change in Android M. As the Google Now Launcher is installed and updated via the Play Store, it's not impossible that we may see this update reach Lollipop as well, but if so, we have no way of knowing when.

Your only option, which I know you're not interested in, is a third-party launcher.


how do i rename the video file after i export it? I downloaded some videos to my android tablet from drop box. I then edited the videos together as one file and am ready to upload to a business site which the files are required to be named a specific way.  I cannot figure out how to rename the the completed file and meet the requirements of the site. When I click on the file in my video folder the only option I get is to delete the file. Can anyone help?

either try another file explorer if you are not familiar with the default one (usually either a "right click" or long hold to get the file rename option).

my personal favorite since it is double-windowed is total commander or you can try that ES file explorer (ad-supported maybe)...


TWRP OnePlus 5T not asking for encryption password I want to flash the new Update for the OnePlus 5T but TWRP is not asking for a decryption password as usual and hence cannot mount the data partition.

It's possible that this is not working since the last update (OnePlus 5T OxygenOS 4.7.6).

Is there a way to force the decryption, for instance by some command in the TWRP terminal? Or is there a way to reset this?

In the Android settings, the Encryption Option is not changeable, it just says "Encrypted".

UPDATE: Obviously OTA Updates are possible now, I don't know how. Till now, with custom recovery and/or root this was an issue and not possible so you had to download the Update manually and install it through TWRP or other recovery.

During OTA Update, the recovery was overwritten with the original from Oneplus.

The option for Smartphone encryption in the settings remains unchangeable, so I believe I could not change the code if I wanted to.

From the TWRP terminal enter the command twrp decrypt <your password>

Locked out of Tablet I have been locked out of my tablet by someone who is asking for money to unlock it.  I was given 3 days to do this.  I know it is a scam.  How do I unlock my tablet?

The likelihood of you being locked out of your tablet again after entering is very high if it is a virus, you can take your important data such as photos off with a computer.
If you have root, adb and USB debugging you can reset the lock by typing this into adb;

adb shell
su
rm/data/system/locksettings.db
rm/data/system/locksettings.db-wal
rm/data/system/locksettings.db-shm
REBOOT

As a last resort you can re-download the system image and flash using something like twrp and then install apps again from the play store. Google now saves app data for some apps so you won't lose everything and some data is synced to your account.


How to buy application previously downloaded from GetJar? I have Agenda Widget Plus downloaded from GetJar. Now I would like to pay for it, because I find it very useful and I would like to reword author of this app. On Play Store it is listed as already installed and I cannot pay for it.

Any idea how can I do it?

You will need to uninstall the app from your device and after that the Play store should allow you to purchase it.


Is there a way to change device type on Google Play I have an HTC One V, but I rooted it and installed CyMod 10.1. The problem I am currently facing is that the device shows up on Google Play as HTC One V which came with 4.0, whereas my phone now has 4.1.

Since it shows up as One V (4.0) many of the downloads show up as non-compatible with my phone and hence I cannot install them.

Is there any thing that can be done to remedy this?

You can try Market Helper; requires ROOT.

  Market Helper is a tool for Android that helps users to be able to
  change/fake their rooted devices to any other devices. For example, it
  can turn your Nexus 7 into Samsung Galaxy S3 in a few seconds. No
  reboot is required.


How to delete google play? I want to disable or delete google play store (I don't want the person who has access to the device to install any apps, and I want to free up some space while I'm at it).

I have root. Where are the files stored (such as the apk, odex)?

Is it in /system/app?

Use titanium backup, which lets you disable/remove apps like that. Or, flash a new rom that doesn't include gapps, download a gapps package and remove the Play Store, then flash that modified package.


Samsung Galaxy S stuck upgrading firmware. Should I unplug my phone? Should I keep on waiting? I tried to upgrade my firmware on my Samsung Galaxy S using Kies

The Firmware upgrade appears to have gotten stuck.

Kies says

Upgradeing firmware... Do not disconnect a mobile device from the PC during upgrade process
Progress Bar has "Upgrade is in progress.." and is stack at about 1/3

The phone screen shows a green triangle with Downloading... below it and "Do not turn off Target!!! at the bottom.

It has been this way for about an hour.

What should I do?

Should I unplug my phone?
Should I keep on waiting?

I really don't want to end up with a brick.

I disconnected the cable

Kies popped up an error message which said, the upgrade failed and offered to try to recover for me.

By following the instructions on screen I was able to recover my device.


Configure audible alarm in cyanogenmod's silent mode I recently installed cyanogenmod 12.1 (snapshot, 2015-09-01) on my HTC One M8. Following my habits, I tried to activate a silent mode. There was the first problem: CM only has a normal and a (total) silence mode. I was used to normal, silent but vibrating, silent and non-vibrating.

The silent modes on stock android I knew before (and on HTC's android), all made an exception for alarms, you could hear them even though the phone was silent (and I don't mean just vibrating).

What do I have to do to get a silent mode, that allows audible alarms on CM?

Since lollipop 5.0 and above, these modes are changed and are accessible via Settings > Sounds > Interruptions.

All Interruptions:
It is equal to general mode. You get ringtone and notification sounds. And you can set volume for them. When you decrease the volume to minimum, it becomes vibrate only mode. Alarms, all calls and notifications work sound when volume is set, and vibrate (not all) when volume is minimum.
Priority Interruptions
You get priority notifications. Alarms are always priority interruptions. You can actually tweak this in Settings > Sounds > Interruptions and choose if you want to be interrupted by calls or messages or events and reminders with fine grained tuning to from anyone / contacts list only / starred contact list only. When volume is set to minimum, goes to vibrate only mode as above.
No Interruptions:
Basically no interruptions. Equal to complete silent mode. You wont get any sound/vibrate for calls or messages or alarms or any other notifications.

So, if you want alarms in silent mode, you may choose Priority Interruptions and tweak it with/without calls/messages/events as per your needs.


How to turn off multiple desktops on Android 4 (LG Optimus L9 P760)? I would like to turn off multiple desktops that are on my Android 4 phone (LG Optimus L9 P760, if that matters). I can switch between them with touch, but I don't need that feature. And most of the time, I use it by mistake (when I want to click an icon close to screen's edge). So it's more like disadvantage for me to have multiple desktops.

Unfortunately, I cannot find any such position in top menu, settings menu etc.

Try "Nova Launcher" app from the Google play store. The "Nova Launcher" has ability to customize home screens and etc. Try this and check your results.

How to help with Android translations? I'm a Android user. I've used both G1 and my current phone Nexus One. The one problem I see in Android is that it lacks a good translation for my native language (Spanish), so the question is: where do I have to go to help with Android platform translations?

Thanks!

I would start by trying the Android Contributors Google Group.

Here is a thread on reviewing Googles own Catalan translation work, for example.


LG Optimus P500 system essential apps deleted accidentally I recently rooted my LG P500 successfully.

But after that, in removing some bloatware I deleted some of my system apps.

After that my notifications area is visible but my home screen and apps screen are not visible.

Also, I performed a factory reset to the phone. So the USB debugging is gone, so cannot connect through adb.

Please help!

I got this :) . Everything was working normally, but only the system default packages were deleted. I used LG MOBILE SUPPORT TOOL and update it again, which brings the phone default ROM to its original state. Thanks for the reply.


What's the default Nexus 4 indicator LED behavior? What is the default behavior of the Nexus 4 indicator LED? When is it lit, in what colors, and why?

Google's official Nexus 4 documentation doesn't apparently cover the LED. I googled and found apps or articles on how to customize the LED behavior, or reviews mentioning the LED without further details, but no descriptions of how it's supposed to work by default.

99% of the time the LED means "new, dismissable notification". I am unsure exactly how the LED color is chosen, but it seems to be based off the homescreen icon of the app; IMO has a blue icon/LED, Messanging (texts) has a green icon/LED, and Gmail has a while icon/LED. The color is consistent each notification from the app, so you will learn which color means which sort of notification.

You can also apparently control it via applications (and presumably by tinkering with system settings somehow): Light Flow can set the colors for Nexus 4 notifications per-app. I haven't tried it myself, but it claims Nexus 4 support.

You can see (I believe) all the colors the LED can show in this (surprisingly long) video. Most of the colors chosen are easily distinct to anyone with typical color vision. If you have partial colorblindness or apps with overlapping notification colors, the notification color changing apps might be of use to you.

The LED can also Flash red when the battery is extremely low and the device won't otherwise turn on.

Possible to install a 1 GB game into external storage, how? I am using Android 6.0 marshmallow. I have 8 GB internal memory and 64 GB external memory (storage). Now I got a game from a friend which needs 1 GB of storage and I have only 400 MB as internal memory remaining. The file and directory I got from him is as -

a. game2.apk 24 MB

b. com.gamecompany.game2 (folder) 800 MB .

When I open the folder/directory I have another compressed file saying main.xx.com.gamecompany.game.obb which seems to mean it needs to go to either the data sub-directory or the /obb sub-directory, don't know which.

Now how do I install it so that the game is installed and it takes all the files it needs from the external storage. If possible I would like the game to be installed in the external storage there and it should be able to find the game files from external storage by itself. I do not know if it is possible.

Is there a way to do it ?

Sorry for no instructions,
• Android folder is on internal SD Card
( /sdcard / android / obb)
• Game data stays inside folder (not renamed)
• Install but don't open apk until data is copied !

What is NON-HLOS.bin? For what purpose it is been made? In new builds I have notice that file but i don't know for what it is used while installing an OS.
Someone answer please!
Thanks

It's the modem/baseband firmware (or to be precise, often a part of it). Not every build would update it, but major builds often do contain tweaks to it.


How to automatically use SKYPE when calling international number? I'd like to program my phone such that if I call an international number it'd automatically use skype (or ask me to connect to skype if not connected), and if I call within the US it'd just use my phone.

Examples:

+1 -> always use my phone

+56 (or other international codes) -> always use Skype.

Any suggestions?  I think tasker could help but I am new to tasker so I am still looking on how to program this kind of flows in tasker... I am open to other software/ideas as well.  Maybe it could be even more general, instead of using skype it could use any other VoIP good service (I am mostly familiar with Skype but I am sure there are other great services).

Thanks in advance!

On Android => 2.3 there is an option in phone settings under Internet Call Settings to add VOIP accounts as well as option Use Internet calling with the following options:

For all calls when data network is available
Only for Internet calls
Ask for each call

Using the third option is the closest you can get currently to your required way of doing this, using a regular SIP instead of Skype.

*Note: Some devices might not have these options even though they are later versions.


How to move Applications from phone to SD Card? I have recently purchased Sony Xperia Tipo Dual phone, I couldn't find to move the apps to SD card. We can able to move the Apps from phone standard memory to Phone Internal Memory.

Can any one give me the solution to move the Applications from phone to SD Card?

As the phones internal memory acts as the sdcard (internal SD card), that is what Android moves apps to.

You can use a 3rd party app to move it to the external SD Card, however.


How common is ARM NEON support among recent Android phones and tablets? Some ARM processors support NEON extensions for acceleration of certain maths operations useful in multimedia, 3D graphics and the like.

How common is NEON support on Android phones and tablets made in the last three years (since 2016)?

To get Google Play Services, devices must follow Android Compatibility Definition Document and since Android 6.0 - Native API Compatibility has required Advanced SIMD (a.k.a. NEON):

  MUST include support for the Advanced SIMD (a.k.a. NEON)

Android 6.0 was released in October 2015. So if the device originally sold with Google Play and included Android 6.0 and up, it should have NEON support.

Realize that older devices sold with older versions of Android didn't NEED to have that requirement but by that point most mid-tier and high end devices had NEON support.

Move Apps to SD Card Using Application Manager . So, you must install Application Manager first

Navigate to settings on your phone.You can find the settings menu in the app drawer.
Tap Application Manager.
Select an app you want to move to the microSD card.
Tap the Move to SD Card button. If you don't see a Move to SD Card button, the app cannot be moved. Most preloaded apps cannot be moved to an SD card. If you don't see Move to SD Card buttons on any apps, your device may not support this feature at all.

If you wish to move an app back to the internal memory, hit the "Move to device storage" button.


ADB pull stops after first error I am trying to do a full copy of /sdcard of my unrooted OnePlus 3T to my Windows PC.
So far I've tried:

adb pull /sdcard/ C:\mylocalfolder\
Works OK but as soon as there is an error it stops the process, so the copy process has been truncated. The error is due to a file containing ":" in the name, so it can't be copied to Windows.

adb exec-out tar c sdcard > sdcard_backup.tar
Doesn't work, it stops inmediatly and creates a corrupted 4kb file.

Copy the files using Windows via Data Transfer mode
Windows halts calculating time to copy files.

Adb pull would be the ideal solution so far if is there a way to skip/ignore errors so it can continue copying the files, or perhaps try to skip the files with certain characters.
I've tryed both Adb version 1.0.32 and 1.0.41 (latest version as of July 2020).
Any suggestion?


USB tether android to laptop, use laptop as wifi router I have unlimited tethering via usb, but not wifi via metro...  so can I tether my phone to the laptop (via usb) and use the laptop as a wifi router?  Virtual routers don't seem to be able to pick up on the "pda net modem" as a viable connection to share, and creating an adhoc isn't working either.

If you have the $60 dollar plan with metro your wasting your time with Pda. If your phone can hot spot use. Metro will not charge you anymore for this at the higher price. I did it. You'll get messages that say otherwise.....ignore them...there's a disclosure that now states they no longer charge for Hotspot on the 60 dollars plan.


Auto-rotate only for YouTube app, disabled otherwise I find auto-rotate really annoying so I generally have it turned off.

Unfortunately, when I'm playing a YouTube video, it's equally annoying when I try to tilt the screen and then remember I have it turned off  :)

I would like a way to have auto-rotate working as usual when a YouTube video is playing, otherwise disabled.

Is that possible? I would like it all handled automatically, I'm not really interested in apps or widgets where I have to toggle a setting manually.

P.S. My phone is a Galaxy Nexus.

Alternatively, my default recommendation for cases like this: Tasker. Use a profile like this (abstract):

Condition: App (select "Youtube", and optionally other apps you would like to have autorotate turned on)

Task: Display->Display Rotation: Set On

This way, whenever one of the selected apps runs in foreground, autorotate is turned on -- and as soon as that condition is no longer met, autorotate is turned to whatever it was set to before. To make sure to have it turned off afterwards, you can add a so called "exit task":

Exit: Display->Display Rotation: Set Off

Hm, looks like currently I answer every 2nd question with "Tasker"...


Nexus 7 2013 not playing nice with Windows 10 I did something to my Nexus 7 and need to transfer files via USB in recovery so I can reinstall my Android OS.

Unfortunately every time I plug it into the USB I get an error. In Device Manager I see my Nexus as "Unknown USB Device. Device Descriptor Request Failed." I try to manually install the drivers but they do not work.

I have searched the web and it seems like a compatibility issue between my newer USB 3 ports and the USB 2 standard of the Nexus 7. No matter how I try I can not get it working with the PC.

I have tried using a Kingwin USB hub and connecting the Nexus 7 through there without luck. I tried connecting to other Windows 10 machines (all ASUS) and have gotten the same error.

I tried entering ADB mode without luck. I tried getting the device to read a USB stick via OTG without success.

I can't find a Windows 7 machine to try and connect it to. I think that would work but I don't have one.

Is there a solution for this?

What driver did you try installing?  Try installing the Google USB Driver which is in the Android SDK as outlined here.  I am assuming you've got the Android SDK installed and setup on your computer?


Force Google Chrome to load background pages I open links via context menu item Open in background but background pages begin to load only when tab is selected.
Is it possible to force Google Chrome for Android to load pages which are opened in background?

No, it's not possible, because it makes a little sense. Chrome is a multi-process browser and it uses dedicated processes (in Android terms, Services) for rendering pages. On Android, processes working in background are usually aggressively killed by the system in order to free memory for foreground processes. It makes no sense to do loading of background pages as a renderer in background will most likely be killed soon, it will be just a waste of network and CPU resources. So Chrome just creates a placeholders for background tabs and only "fills" them when the user switches to them.


How to assign Mobile Data's public IP to host connected on hotspot? I've looked around but found nothing on this subject.

I have an Android phone with a public IP given by sprint. Tethering on Android uses NAT, so if I want to access any of the devices behind the phone I have to use port forwarding (Which I'd really rather not do). Is it possible to set tethering to bridged (Disable NAT), so the device behind the phone will be given the public IP?

Have a look at this thread about using open VPN. Here you can give public IPs to devices using Open VPN, I think.

Or you could find another tethering app which supports this such as PdaNet+ which may have more control.


Unlock bootloader using fastboot using Ubuntu/Linux I am trying to unlock bootloader for my HTC Legend.

I have ADT (Android SDK according to release 21.1) on my Ubuntu/Linux box.

While following the HTCDev instructions to unlock bootloader of HTC Legend.

I can adb devices that results as under

List of devices attached
HTXXXXXXXXXX    device

But fastboot devices does not result any thing.

When I reboot my phone to FASTBOOT USB mode and plug in the USB cable to phone and connect to PC/Ubuntu.

fastboot oem get_identifier_token
results as following and sit idle.
< waiting for device >

I have cross checked for certain things:

The default USB mode is Charge Only
The USB Debugging is enabled

But on my ubuntu box there are no drivers and no HTC Sync installed.

What am I missing here?
Can I do it from Ubuntu, as I don't have windows?

UPDATE: My device's HBOOT is 1.00.0000

UPDATE2: I just tried with sudo fastboot devices and returned.

HTXXXXXXXXXX    fastboot

Now when I do sudo fastboot oem get_identifier_token it returns:

...
(bootloader) [ERR] Command error !!!
OKAY [  0.010s]
finished. total time: 0.010s

Linux users: If you're stuck in "waiting for device", make sure you run fastboot as root, such as:

$ sudo ./fastboot oem get_identifier_token
...

  How to upgrade / swap SD card without losing data and installed apps?

I have a 2gb sd card and it's full I can't put more music,photos and videos.I will buy an 8gig sd card.I wonder if it will work if I copy all of my apps from the 2 gig to 8 gig I hope it will work

It will not work in case you move all your data to PC and then copy it to the new sd-card(it true for Windows,Linux, Mac as ownership of all applications will be changed)
If you have additional slot for sd-cards on your device then copying data to the new card and then replace the old one with this one. It should work with all rooted devices)

Try copying your apps using some special utilities which copy data saving permissions and ownership. I hope dd on linux will work


Making volume controller more fine My Sony Xperia has buttons to control the volume as most of other smartphones. The control is rather coarse, there are only 8 steps including max volume and silence. Especially for use of (Bluetooth) headphones this is silly coarse.

How can the volume adjustment more fine? I would like to have e.g. 32 steps here.

Edit: The device isn't rooted and I don't plan to do so.

No way to do so if your device isn't rooted.
Every app you find for the same will require root access.


Droid Turbo Won't Receive Texts I have a Motorola Droid Turbo with Verizon as my carrier. Earlier this week (May 30th), my phone began to receive text messages intermittently. I now go hours without receiving any text messages and then all of a sudden tons of texts will come through that I had missed. Even when I receive the giant dump of texts at that time, not all of the texts will come. I've missed a bunch of texts this week that have never shown up. This is more apparent in group messages. Also, most of the time when I send a text message to someone it will tell me that it failed to send even if they actually received it.

Here are some of the things I've done to try and fix it:

Turn my phone on and off (many times, and for long periods of times)
Turn my WiFi on and off
Turn my bluetooth on and off
Backed up all of my texts on to Google Drive and then deleted them all off my phone
Switched from using Textra to using Google Messenger
Switched from using Google Messenger to using Verizon Messages
Switched from using Verizon Messages to using the stock messaging app

I've read a bunch of different forums, but nothing seems to be working. I don't think it's the carrier because no one else on my plan is having problems, and I will often get a notification on my phone saying "MMS Timeout - click to retry" and then I click and it doesn't do anything.

I don't really want to reset the phone, especially since it might not fix anything. Does anyone have any other suggestions?

I went to this Verizon troubleshooting page: https://www.verizonwireless.com/support/motorola-droid-turbo-troubleshooting/#/main/device/&MOTXT1254&8617/troubleshooting_steps/17893&17885&&&&Troubleshooting&&/step/

The step that finally fixed it was sending a text to myself. I have no idea why that does anything, but it is now working fine. Hopefully it stays that way. I posted the link here in the answer so that anyone with the same problem can go there and walk through the steps.


Locked out of Samsung Galaxy S4 tablet I cannot remember password on my tablet  Samsung Galaxy S4. It just keeps giving me options to enter, I've tried 30 times I should have never changed it in the middle of doing something.

How to set the YouTube app to play 360p instead of 240p video? In the YouTube app there are only options to play 144p or 240p. Is there any way to make it play 360p?

When I access YouTube from Chrome it plays 360p videos; the quality of the same video was way better when played from the browser.

The YouTube quality settings are determined by each video (although if you select a higher quality, it will default to that for the next time).  Hit the three-dot menu button:

Then the Quality cog button:

Then you can select the quality setting.

Other videos might have more options for the quality setting:

This completely depends on external factors like, for example, the size of the source video that was uploaded to YouTube.

You can also (from the 3-dot menu on the app Home) go to Settings → General to turn off the "Limit mobile data usage" option, which will allow videos to default to higher quality when you are not on Wi-Fi.


Connecting android tablet as testing device I have a problem related to connectivity between my desktop (Windows) and tablet (Android 4.1). I bought a new device (Colorovo City Tab Vision 7) and now I want to use it for testing of my applications, because emulation of android is very slow on my computer, although I forced it to create snapshot every run.
I have downloaded SDK with Google drivers and also some unofficial drivers I found on web.

When I connect my device, it first appears 'Other device' (label is CTVision7) and it's marked as unknown. I tried to install drivers (Google) for it, but windows said that they aren't suitable for my device, as it's not able to find them in specified directory.
After these attempts I tried unofficial drivers. Their installation worked and now my device appears as Android phone, what seems to be good.
But when I run adb devices or launch application in eclipse, there's no avaible device.
I have turned USB debugging on, so it should work.

Am I missing some step to make my device avaible for debugging, or are my drivers wrong? Is there any way to get drivers which surely work?


Samsung Galaxy Grand Duos not embedding GPS information in Photos My Samsung Galaxy Grand Duos is not embedding GPS information(Latitude/Longitude) in Photos taken from the phone camera.
I have enabled GPS option in main settings, and also set the GPS tag in the camera settings.
The latitude and longitude information is not appearing in the photo details.
I do not wish to enable the "Mobile Data" option.  I do not need the location information like place name, etc... I only need latitude and longitude information.
What other setting am I missing?

It could simply be that the phone doesn't have a GPS fix when you take the photo. It might be different in your phone's camera app, but most camera apps start asking for the position when you start the app, and if there isn't a fix when you hit the 'shutter release', they save the photo anyway, rather than holding you up waiting for a GPS fix. Getting an accurate position can take some minutes if you're hidden from the sky, so it's easy to take the photo first without realising.

Check the location icon in the notification bar, and be sure it has stopped blinking before you take the photo.

How to prevent apps and processes from launching in background and slowing my device I recently installed GravityBox on my S3 mini. In one setting, I could change the physical button actions, so I decided that a Double Tap on Back would close the current app. It works fine. But it doesn't close it like when I do it manually - that is to say remove from recent apps - it just forces close so when I'm closing that way some apps like Geometry Dash or doesn't save my progress.

Actually it does more than that. I think it stops the most recently launched process since when I'm in some app and sometime I double tap back and it closes another app. And the big problem is that those apps slow drastically my phone. They prevent an action from being executed, they slow the navigation, they make games lag... They are named Google Play Services, Play Store, android.process.media, Messenger...

And oddly, when everything becomes slow and laggy, all I have to do is to double tap multiple time back button, and when every other app or process is closed everything is fast. But I often close the real current app by doing so. And when I'm in the launcher, I can tap a thousand times back, and there will always be a process called PageBuddyNotySvc the wouldn't close. Or it's LogProvider.

Naming Gavity box running on your device implicates it is rooted, so you could use the full powers of Greenify. Greenify "temporarily freezes" apps which are running in background (of course only those the user specified). Other than with "deactivating" or "freezing" apps using e.g. Titanium Backup, such apps stay available in all places (including the app-drawer) and, in most cases, even can receive notifications (GCM etc.). It's more "putting them to sleep" than "freezing them".

Greenify can be used on non-rooted devices as well, but its full powers are unleashed with root (and the donation package plus the corresponding Xposed-module). Definitely worth a look.


Is it possible to turn an Android tablet on or off over a wired connection such as USB? I'm looking to use an Android tablet as a carputer, yet one problem I have is how to get the tablet to turn on and off when I turn my car on and off. With most carputers people will use special automotive power supplies to solve this problem.

What I want to know is if there is any way I can simulate pressing the power button, but through one of the wired interfaces such as the USB connection? Or would my only option be to open up whatever tablet use up and solder extension leads to the power button contacts, and then figure out some way to simulate a power button press when my car starts?

The "power" button on Android tablets does not behave like that on a computer.   It is really a control for whether the display is on or off, not the tablet, which is generally always on.   You  may be able to get what you want by setting the "Stay awake while power is connected" setting under developer options, and setting the screen timeout to a short value under display settings; if you connect the charging cable to a power source that goes on and off with the ignition, you should be good to go.

If the standby time of your tablet is not enough to handle your typical time with the ignition off, you may want to use an app like Tasker or Locale to set additional rules, like turning Wifi or cell connection off when the car's power is off.   If there's data you want to sync overnight, you could turn Wifi on (for example) an hour before you leave for work.

You may also want to disable the screen lock to minimize distractions while driving, but keep in mind the implication if you have any personal information on the tablet.


rooting device stops usb-host-mode working After I rooted a Nexus 10, the USB Host mode is no longer available.

I have checked the original unrooted device with Chainfire's 'USB Host Diagnostics' tool and it recognises a plugged in Arduino whilst scanning for connected devices, but nothing is detected after rooting.

Originally the device had Android 4.3 - build JWR66Y, and USB Host mode worked. I rooted via the Nexus Root Toolkit and installed a rooted image of the same build, and now the device isn't detected.

Has anyone experienced this? If this is being caused by a bad image, can anyone recommend one which will work?

Update:

The rooted kernel version is

3.4.39-g446c9cf
android-build@vpbs1.mtv.corp.google.com #1
Mon Jun 10 17:11:40 PDT 2013

According to this forum thread and this bug report, it seems that there has been a regression regarding USB modes in the kernel used in 4,3 (The version that you posted).

It seems that there is a problem with that kernel specifically, but nothing else in the ROM, that breaks USB Host Mode in some cases. There are a few possible solutions:

Flash a different Android version. An update to 4.4.2 should fix things (as it did for you).
Flash an alternative, third-party kernel and try your luck. You Mileage May Vary.


How do I empty the Downloads Folder My internal sd card is full because the downloads folder my browser saves stuff to contains a bunch of old files.

How do I empty this downloads folder in android?

Download a file mananger -- Astro is quite popular -- and delete the contents of /mnt/sdcard/Downloads. The path may be different if your phone has large internal storage.


Trying to update Nexus 5 to 5.1.1 and using Nandroid backup I'm trying to update my Nexus 5 to 5.1.1, but when I restore my Nandroid backup I lose the update.

What should I do?

That's because you backed up the older Android version, so when you update from 5.1 to 5.1.1 you install a new version then you try to restore the backup, you will got the previous version 5.1.

You can try to restore data only, but i think it will crashed.

For future updates use Titanium Backup to backup all of your data and then when you install the new version of Android you can restore it using the same app, Actually i always do that.


Did I just brick a non-rooted device? I have a non-rooted Onyx Boox C67ML Carta running stock Android 4.2.2.

I just installed Orientation Locker. I transferred it from my phone using Shareit, but on my phone it had come from the Play Store.

Once installed, when I tried to run it, the whole device totally froze. See below for a picture of what it looks like.

When this device had frozen on me before, I had always been able to force a reboot by holding down the power button. That does not work in the current situation.

I carefully used a knife to take off the back cover to try and find the battery. The battery does not seem to be removable without physically breaking the device.

I suppose I could wait for the battery to run out. It was quite low when the incident occurred. It may actually be out already, and the device off, since e-ink screens may continue to display the last picture they showed when something goes wrong, even without power.

What should I do?

The device was not bricked. After a few hours I held down the power button again, and the frozen screen was replaced by the "no battery" screen. After charging, the device is back to normal. I caution users of this particular device not to use apps that try to force the systemwide screen orientation.

It was lucky that the battery was nearly empty when this happened. I suspect that if the battery had been more charged, the wait could have been significantly longer.


Create an image of entire phone My phone was out of my possession for two days. I would like to save an image of the entire phone and run it in an emulator to be able to debug/reverse it so I can check it out for malware or any other software that may have been introduced. How would I be able to save everything as is to be able to emulate the phone? Is this even possible?

I have a Droid X2 running Android 2.3.4, no root, no custom ROM. I'm factory default b/c of warranty (Verizon).

As you said your phone is unrooted, which has two implications.

You can't, without altering the phone thoroughly check whether it was tampered with.
It makes it harder to tamper with the device.

So what you're asking for is not possible without possibly destroying evidence of tampering. If you're afraid what they might have done to it I suggest two options: either do a factory reset or buy a new phone.

Even if you could look for evidence of tampering be aware that you can never be sure. Checksums and modification dates can be faked.

If I was you I'd ditch that phone. I could never feel safe knowing that someone I don't know access to it for two days.

Prevention is another thing though. If you want to make sure that this doesn't happen again watch out for these things:

Screen lock. Use at least a complicated pattern lock makes an attacker harder to access your data. Even better set a pass phrase.
Root This gives complete control to anyone who has physical access to your device. Plant fake call logs? Done! Fake Text messages? Done! Install undetectable surveillance software? Done! You get the idea. Superuser (the de facto standard app for managing root access) has an option to require a passcode as a prerequisite to granting root. Use it.
Disable USB debugging While it's not too dangerous in itself if coupled with root it can provide access to the entire contents of your device even if you have a screen lock.
Encryption If your device is running android 3.0 or later you have acces to full device encryption. Use it.
Backup apps Apps like Titanium Backup can backup sensitive data to your sdcard. Even if you did all of the above, all an attacker would have to do is take out your sdcard an voila! Full access to everything! Make sure that your backups are encrypted with the strongest possible encryption.


Music Player won't detect music on USB. Galaxy S7 For some strange reason, my media player (I have tried MediaMonkey and Google Play Music) won't detect my music on my new USB. I can play music when I select the music file from the file explorer, but the music won't show up in either music player. I have checked to make sure there weren't any .nomedia files, and I selected the USB as the storage device in both MediaMonkey and Google Play Music. I refreshed and cleared caches, but none of these things help. And yes, the music files are supported by the players (I have both .mp3 and .flacs, niether show). Also, the files work fine on my PC, so I know they aren't corrupted or anything like that. I have also restarted my phone several times.
Phone: Samsung Galaxy S7
OS: Android 7.0

Okay, so I just ended up buying Poweramp. It didn't have any issues reading the files off the USB. Sadly this cost me an extra 4$, but I was sick of trying to get Google Play to read the files properly.


How to share via mail always to the same recipient in one touch I frequently share things by sending me to my gmail address. So I make 4 steps:

tap share icon
tap Gmail icon
type my own address
tap send

Is there a way/ app that automatize all these things : one tap on this app on share popup send directly "the thing" to a pre-parametrized recipent(s). ?

Finally, I have founded an app wich makes exactly what I want : share in 2 taps (not 1, it's true) : it's named InboxIt

With the free version, you can only quick share to your self gmail address, but it's largely sufficient for my usage !


Bluetooth signal strength bug with my car's stereo i have problem with xiaomi mi a1 and bluetooth radio of ford fiesta car.

I connected an Android phone to a vehicle via bluetooth to make/receive calls.

Connecting the device via bluetooth was simple. Making calls, however, was a challenge. The vehicle reports that the Android phone is always without cell reception, and therefore will not place calls. Furthermore, the vehicle's head unit (aka receiver) shows a "no reception" indicator for the Android device's cell reception.

Placing calls from the Android device through the vehicle's audio system works as expected. This also shows that the Android device has ample cell reception to make calls.

with the bt hci log i see that:

when phone connects bt to radio, the phone sends this info:

+CIND: 0,0,1,3,0,4,0

legend +CIND:("call",(0,1)),("callsetup",(0-3)),("service",(0,1)),("signal",(0-5)),("roam",(0,1)),("battchg",(0-5)),("callheld",(0-2))

when the signal strength on the radio disappears and reset all (zero) the phone send this info:

+CIEV: 3,0 +CIEV: 4,0

3 = service, 0 = no service (previously was 1) 4 = signal, 0 = no signal (previously was 3)

but the phone in realty upgrade the signal strength from 3 to 4!!!!!

At first sight the source of the problem in your log is mIsSimStateLoaded=false.
The true value of the service indicator (1, available) is logged, but because of this SIM state equal to false HeadsetService sends 0 (not available) instead of 1.
The true value of the signal indicator is unknown, because of service=0 HeadsetService sends 0 instead of the true signal level indicator (this temporary 0 value is logged, in fact it is not mSignal value).
Possibly Android HeadsetService contains an error with mIsSimStateLoaded flag processing, because it can be cleared on every phone service loss, but set only on ICC_LOADED broadcast. If so it is strange because a lot of Android phones shoud have the similar problem.
Have you tried to reboot the smartphone before connecting to headunit?
Upd: Hmm, this SIM broadcast is sticky, than maybe this is bug by Xiaomi, not Android.


How can I change the search engine from Yahoo in the "Firefox Search" search provider? When I installed Firefox yesterday, I immediately set my default search engine to DuckDuckGo and removed Yahoo from the list. Today, I discovered that Firefox has a search provider built in for when you swipe up from the home button. I decided to try it out, but noticed that the search engine was set to Yahoo there. The settings only had an option to clear search history. I also tried tapping the Yahoo logo and the search icon, but it only started a search. Is it possible to change the search engine in this thing? Or is the Mozilla-Yahoo deal that far-reaching? Images:

If you tap on one of the search engine, it should give you this dialog box which you can tap on "Set as default":

I tested it on a Nexus 6 and it does switch the search provider used in the Home-button swipe search.

If this dialog doesn't appear for you or if the "Set as default" here doesn't change your search in both the URL bar and Home Button search, then it would be a bug. You might want to report the bug in Bugzilla@Mozilla, with your device and OS version.


zsh scp completion of remote files doesn't work when running SSHHelper Running SSHelper is a great way to access files on your phone. But completion of remote files (scp and rsync) using zsh doesn't work though. While using sshfs is a workaround but sometimes you just want to pull/push a quick file, it's not really satisfying.

Where lies the culprit, and how can I get file completion working properly via zsh?

The culprit is android's crippled ls command. Zsh's completion run ls -d1FL which /system/bin/ls doesn't understand.

A way to fix this is to edit /data/data/com.arachnoid.sshelper/home/.ssh/environment such that /data/user/0/com.arachnoid.sshelper/bin is the first entry in PATH. (SSHelper ships with a more complete ls)

Note that SSHelper might rewrite this file on updates?


How to lower battery consumption on a S6 edge Im not sure on what site I should be asking this.
So my phone is an s6 edge and it consumes too much energy. Im curious of how we can reduce the phone consumption using some app or root option I can use.
Thanks for your answers !

There are a bunch of things you can do, but keep in mind that the mythical method of doubling your battery life doesn't exist. You may get another hour or two before you need to recharge.

Greenify (I am in no way affiliated)- An app that, like some other task killers, stops background tasks, but greenify is different. It uses the native force stop function to stop apps that you don't want to keep running. It runs better with root, but isn't necessary.
Turn off WiFi scanning- did they forget to mention wifi never turns off? Depending on your Android version, this option is either within the wifi advanced settings, or inside of the location services (marshmallow and on). You will find an option that says wifi scanning. Turn it off, along with wifi on while asleep if you are it. Wifi use is usually one of the larger drains of the battery.
Use your phone less. We are so hypnotized by there things, and it can't hurt to try and stay off Pokemon go on the bus when you could be watching the scenery or just listening to music.

how to stop a system update upon restart Quick question,

I have an old Essential PH-1 that runs on Android 7.1.1 (Nougat). I accidentally okay'ed it to update to Oreo and it says to allow the updates to take effect to the newer Oreo OS I need to restart my phone. I do NOT want to update to the new OS. I want to keep Nougat OS.

How do I prevent this from happening?

Is there a way to erase these new files so when it eventually restarts it will not finish installing these updated files to Oreo? Or do I have to let it update upon restart and then downgrade  back to Nougat? If so, where do I go to find the easiest way to do that? Any help would be greatly appreciated.

You need to open your device developer option. In case it is not there then click your device build number 7 times. Then in developer option disable auto system update on restart.Link for the image

Can I install from the HTC One X Version or the HTC One XL Version ?? and there is an Unofficial release for HTC One X+ Cyanogenmod or should I install this version ?? Is there any particular reason or defect why Cyanogen didn't release one officially for HTC One X+ ??

Can you please give me the way to Install Cyanogenmod on my Phone ?? I'm a Newbie

The HTC One X version won't work on the HTC One X+, so if you want to install Cyanogenmod, it'll have to be the unofficial build you link to.


seeing someones last seen on whatsapp when they have disabled it My friend has disabled his whatsapp.
But I want to see his last seen.
Is that possible?
I have not tried anything because I don't know what to do

As per the WhatsApp Privacy settings mentioned in their Official Link,
you may not be able to see a contact's last seen info in below situations:

They may have set their Privacy Settings to hide this information.
You may have set your Privacy Settings to not share your last seen. If you do not share your last seen, you cannot see other people's last seen.
You may have been blocked.

And since you already mentioned that your friend has DISABLED WhatsApp itself, it is unlikely you will be able to "last seen" info using Official WhatsApp.


Hide Developer Options in Android 4.2 I know how to show the developer options menu. How do I hide it again?

Clearing the data on the "settings" app will get rid of the developer options on the Galaxy Nexus (at least on 4.1.  Not sure about 4.2), but that may only work on that device.  It doesn't do it on my Galaxy S3.

Note: The above action clears the settings of the settings app, i.e. not actually importanty data per se. You should be fine doing this.

The only other known method to get rid of them requires root and deleting /data/data/com.android.settings/shared_prefs/development.xml.
See Where are the developer options in Android 4.2?


Ubuntu connection woes, device not showing up in lsusb any more I have a really weird issue in connecting my Samsung GS2 to my Ubuntu 14.04 system.

I found the ID via lsusb at first, and added a udev entry. Everything was perfect and I was happily ADBing away for a few minutes. Thereafter, I begun getting "Unable to mount samsung device" (or something similar) popups.

Since then, my GS2 doesn't even show up in lsusb. When I plug it in, the phone behaves as if it has just been connected to a wall charger; MTP doesn't work any more, while it used to fine. I've tried removing the udev config file, restarting phone and pc, and enabling/disabling debugging mode, but still there's nothing in lsusb. Everything works perfectly on my other windows machine.

What on earth is going on here?

The most likely cause of the symptoms you describe is that a pin is bent or broken in the USB connection. With the data pin broken but the power pin connected, the connection is exactly as if As it works on a different machine, that would narrow the problem down to the cable (if you are using different cables on each) or the USB port on your PC. Try a different cable and a different USB port.

As your phone works fine with a Windows PC, that rules out it being a problem with Android itself, so if changing the physical connection doesn't help, we probably can't help you any further here.


Contact sync with android Yahoo app I have email contacts in my Yahoo mail app that were deleted from the web version (I haven't synced with the web version) If I do sync will I loose the contacts from my phone (I dont want to loose them)

It really depends where the contacts are stored. If they are stored in your phone, then even if you sync, they will not get deleted, but if they are stored on your Yahoo account, then as soon as you sync, they will all disappear.

To check where they are stored, go into your regular contacts app and find a contact that also has an email address with Yahoo. If under the contact, where it says connected via, there is just the Yahoo logo, that means that the contact is there through the Yahoo account, and therefore it will be deleted as soon as you sync your contacts, but if it has a Sim card icon or a phone icon, then it means that it is saved in your phone/Sim and will not be deleted.

In this screenshot, in the place where you see the Sim card icon, that's where you should look for the Yahoo icon.


How to get out of broken home screen replacement? I was writing my own home screen replacement, and while trying it out on my ZTE Blade I got into a bit of trouble.

I have hooked the HOME-button, and set my app as the default for it. Too late I realised there is no (easy) way out of such an app.

I have tried:
* holding down VOL DOWN to get into FTM-mode, but that just gives me screen that says "FTM" and nothing more
* Using adb, but it just says my device is offline. Debug mode is not enabled on the phone.

So, how can I:
1) get out of an app that has hooked HOME-button?
or
2) reset the phone with a button-combo or over USB (since I cant access the menus)

Installing new ROMs is something I rather not do.

Assuming you have ADB access to your test device, you can issue the following command:

adb shell pm uninstall PACKAGE

Where "PACKAGE" is the package name of your launcher app (you should know this since you're creating the app in the first place.)

[Edit]
As requested, re-posting my comment as the answer:
Every site for ZTE Blade has instructions for accessing the Fastboot mode via Volume Up + Power button combination. Eg: http://wiki.cyanogenmod.com/index.php?title=ZTE_Blade:_Full_Update_Guide Give that a shot and see if you can access the phone via fastboot.exe (should be in the [Android SDK]/tools/ directory.) At that point you can flash a different recovery image (Clockworkmod, Amon-Ra) that will allow access to /data/app to delete your program.

Android Automatically Adds Shortcuts To Home Screen Possible Duplicate:
  How can I remove unwanted app icons from the screen?

I have a Samsung GS3, and every few days new shortcuts show up on my home screen. How can I stop them from being added? I un-checked Play > Settings > Auto-Add Widgets and they still keep showing up. What is causing this?

Probably you have installed some non-reliable app, which is adding those annoying shortcuts in your home screen. I recommend you to install and make a scan with the free app TrustGo Ad Detector, and uninstall the app(s) under the behavior Create shortcut on home screen.

Also check out under the other behaviors for more suspicious apps and proceed as recommended. Note that some apps use legitimate mobile ad services, like Google's AdMob to monetize via ads, but they are listed under behaviors Leak identity info and Collect location , so just make sure you only uninstall (and avoid to install in the future) applications like online casino games, adult apps/games, and other which you distrust.

Keep making scans periodically (weekly or monthly) on your device to get rid of new potentially risky apps.


How to create a Local Area Network with Android device? I want to use a TCP service running on my phone that needs its current IP to be known. So when the phone is connected to its internet as alone, I can know its IP.

However to speed up this task, I need to make a local network connection with my phone and know its local IP.

The USB/Wi-Fi tethering by phone with PC does all that along with sharing its internet connection, however in this scenario, I don't want its internet. I am already connected with LAN on my PC. and have no internet plan on my phone.

Any suggestion?

Connect it to WiFi or ethernet via cable.
At router or DHCP server settings reserve IP address for Android.

Now you has network and known IP address for your Android device.

P.S. if you don't have router and directly connected to internet via cable - you can emulate WiFi router on your PC (not all adapters supported).


Adjust/personalize auto-correction on Android Using a Moto G Play with Android 7.1.1 installed. Whenever I type the word ie. (that is), this is auto-corrected to one of:

or.
IE.

The auto-correction selected appears to be random (perhaps based on context). I would like to tell my phone to NOT auto-correct ie under any circumstances. If I meant to type or and accidentally typed ie...that one is on me!

Is there any way to adjust auto-correction by manually entering personalised phrases (such as into a dictionary)? I don't want to turn auto-correct off entirely.

Add the word to your personal dictionary.If you are using Gboard:

Go to its settings then Dictionary.
Click on Personal dictionary
Select a language or All languages if you want to add the word for every language.
Click the + button.
On "Type a word", enter ie.. Press the arrow to go back to the previous screen. (You can enter a shortcut for the word if you want but with your word being so short I don't think it is necessary).

For now on ie. will appear when you type and will not be auto-corrected.


Reduce the icon size on an Android laptop running on Remix OS I have recently dual booted Remix OS with Windows 10 on my Lenovo G580 and the problem is that the icons and the taskbar looks so big.

How to make them smaller?

Note- I am using UEFI mode

You can change the DPI.

When booting, press Tab or E to change the parameters of booting, and add

DPI=<Integer number>

In my case, I used 120 and got smaller icons, but you can try different numbers.


Moving pre-installed apps to SD-card (ROOTED) i'm running a Moto E with android version 5.1 Lollipop, and since updating to this version of android I have had constantly so little space on the internal memory that I can't even update the pre-installed apps even though I have as good as as no other apps installed on the phone as well as zero images, videos, music or any other media files.

Therefore I've spent a few days trying to figure out how I could move the pre-installed apps to my SD-card.
So, I've rooted the phone, installed the program called Link2SD and I tried using that program to move the apps. Yet it gave me a warning:

"Failure
pkg: /data/app/com.google.android.apps.maps-1/base.apk Failure
[INSTALL_FAILED_INVALID_INSTALL_LOCATION]"

Then I found that it seems I also need to create a so-called "second partition" on my SD-card, but I've not yet managed to find a tutorial on the internet that worked for me.

Since then I've tried 6 or 7 other similar programs with no luck, in the process reading somewhere that it actually couldn't even be done on android versions 4.0 or later. Is this true? Could someone be a kind gentleman (or -woman) and guide me through this? That would make me very happy indeed.

EDIT:

In short, my two essential questions seem to be:

1. Is it possible to move pre-installed apps (Google apps mostly) to an SD-card on Moto E with 5.1 Lollipop.

2. And if so, how do I create a second partition on my SD-card for this purpose on Moto E with 5.1 Lollipop.

Thanks in advance

Simon

Well since you didn't deleted apps it means that they are on system partition. You can move it to SD card but longer way around. First you need root. Then (I don't know if other app can do this) install titanium backup (note you'll need pro version), than find that app in titanium backup on backup/restore list and in special features find option "convert to user app". After that you'll be able to uninstall app without any other software or move it to your sd card with link2sd or any other app you use for that.
About creating partition on your sd card, I didn't exactly done that but I'll post link here on how to..


How to find out which app uses mdnsd My battery life has dropped massively recently and there's an unrecognised app 'mdnsd' that's using a fair percentage of it.

AFAIK mdnsd broadcasts info about services running to a local network, but I can't think what APIs would need that. How can I find out which app is using this?

This is a bug associated with firefox. From this source: https://bugzilla.mozilla.org/show_bug.cgi?id=1215012.

It is also suspected to be caused by the patch Support Multicast DNS (mDNS)

Further tests showed these results:

 Actual results:

Excessive battery usage when using Firefox beta.
Phone Power setting shows MSNSD with increasing usage.

This issue was mainly noted in beta version of firefox and version 42.

Several users have complained about the issue and this how they resolved it:

  Install this new version, run it once, and the mdnsd process starts
  busily running your battery life down. It took my S5 from 17 or 20
  hours before the battery would run out to 4 hours. This is true
  whether or not Firefox is running in the background. All the
  complaints on the web about this start around November 2014 time frame
  with complaints about the two other random apps, but only a couple,
  and a comment on the Mozilla Bugzilla platform that there was a report
  of extreme battery usage sometime in July of 2015

Source:  What is MDNSD and how do I get rid of it?

Uninstalling firefox proved to be the solution:

  So by uninstalling Firefox, the mdnsd process stopped draining the
  battery for the rest of the day. After recharging the battery
  overnight and beginning to use the phone the following day, the
  Battery usage report no longer shows the mdnsd process!

Source: Mdnsd killing battery?

Probably the issue was subsequently fixed with newer versions of the browser.


Importing APK Files from google play console , then making it run on Android Studio I am currently working for my professor and there was a programmer before me that built the app. I am trying to convert his APK file into my own Android Studio for the full code so I can make updates and re-publish it onto the google play store. I've read online about converter tools and using decompilers, but I am never able to run the actual app once all is said and done, because the green run button is faded out and unclickable. So my question is, is it possible to accomplish what I'm trying to do?

I believe that you want to reverse engineer. Please check this link. Good luck.


Cannot flash factory images to Google Pixel 2 XL Device: Google Pixel 2 XL (taimen)

Carrier: Unlocked (purchased from the Play store)

Image: image-taimen-opm1.171019.011.zip

Ultimately, I'm trying to root the phone by flashing a batched boot.img to the stock image, but I'm unable to flash any images, whether that's the patched boot.img, TWRP, or even the stock factory images themselves. I've already unlocked the bootloader, using fastboot flashing unlock_critical.

sending sparse 'boot' 1/51 (508 KB)...

which hangs indefinitely, never sending the first segment.

I can try booting directly, which yields the same problem:

$ fastboot boot boot.img
downloading 'boot.img'...
# hangs indefinitely

Similarly:

$ fastboot --set-active=_a

will just hang indefinitely as well. I have to restart the bootloader to kill it, at which point it just prints the cryptic error: Device does not support slots (the Pixel 2 XL does support slots!).

The error messages aren't always consistent; sometimes the first fastboot flash boot boot.img command will appear to hang (requiring a restart, similar to --set-active) instead of printing the error message about max-download-size. I've let that run for about fifteen minutes before having to kill it. Unlike system.img, boot.img is only about 40MB, so it shouldn't take that long to flash - something is clearly wrong.

I've also tried this with multiple cables on different USB ports, with the same results.

Ultimately, I solved this by using a Macbook Pro with a USB-C to USB-C cable.

Previously, I had tried it with two different USB-A to micro-USB cables, using two different micro-USB to USB-C adapters, on a Linux laptop with two different USB-A ports and the then-latest version of fastboot/adb downloaded. Unfortunately, I can't be certain what the issue was, but since it happened consistently with multiple cables (and those cables still appear to be working), my guess is that there was a bug with the Linux version of adb/fastboot.


What is the application space limit on Galaxy Nexus? Samsung Galaxy Nexus has a 16GB internal memory and no external sdcard. I'm wondering if that means I have 16GB (or at least the free space left of that memory) to install applications?

Yes you have full 16GB for apps+data together in a single file system. You won't have to do any moving to SD card any more.
Google merged both partitions. It's just one big file system now with sections for the former parts. It's completely transparent, so no worries for you.

Formerly: /data and /sdcard were separate partitions
Galaxy Nexus / Nexus 7 and others running Jelly Bean: One single partition for both, i.e. no need to decide how to divide the space for both any more.

To make it more generic:
The partition layout will however not change for former phones (most probably), so devices which got upgraded to 4.x+ will still have separate file systems for both /data and /sdcard. If your device has an additional micro SD card this will also be separate still.

By the way: This is the reason why there's no USB-thumbdrive functionality any more for the Galaxy Nexus (because /sdcard is not a single partition any more and also there's no FAT32 formatted partition internally (except for SD cards if existent))
