Yes there is. When the community discovered this feature in android 4.1 (the code was exist but has not been declared yet so Google did not open the feature in Settings), I remember playing with this in my Nexus 4. So, here are some commands that I remember for the android Terminal: Create new user: pm create-user User_Name To switch between users: am ...

This issue has been plaguing Whatsapp since its inception. I have had long email conversations with their support team on multiple occasions. Even uploaded a detailed video explaining the bug: Check it out here: https://www.youtube.com/watch?v=-bldIuA-OjU This was their reply after about about 20 emails explaining the issue. I gave up after that. To ...

After probing the firewall logs, it appears that the grey/blue icon is triggered depending on whether or not your device has access to Google Play. In our case, I had to open tcp-udp port 5228 (as per http://support.google.com/googleplay/bin/answer.py?hl=en&answer=2651367) and after turning wifi off and back on again, the icon became blue. I can't ...

That feature was removed in the 4.x versions of Android. I use UberSync for my contact syncing and it works great. Haven't had any problems with it and it also has a setting to import high res contact photos. I would recommend that. Set it up once and forget about it.

I don't think there is a good way to do this - the issue isn't that the private number is being hidden by your phone, it's that the phone company isn't transmitting the caller id info to you at all. So there shouldn't be any way for you to get that data working strictly from your phone. Unless you know people who regularly block caller ID data, but don't ...

adbcontrol can do this. It opens a window containing the phone screen on your computer, so you can use it when the phone screen is broken, and you can click and type in the window to control the phone. To install adbcontrol do: wget http://marian.schedenig.name/wp-content/uploads/adbcontrol.zip unzip adbcontrol.zip Now edit config.properties and change: ...

There are likely two calendar apps on your system. Stock Android includes an app and Google provides one as well, which might be preinstalled on your device, or you may have downloaded it without realizing it. They both look very similar (which is probably why you thought they were the same when you held on them for the App Info screen). Check in your app ...

Turns out you can forward all traffic over the network by entering 0.0.0.0/0 You can then check by doing a google search for your IP and it should now be the public IP of your VPN's gateway

You can find the official Factory Images from Google's Factory Images for Nexus Devices page, and the download contains all that you need to downgrade. Unfortunately, this means you'll lose all data on the device, so be sure to make backups beforehand. Basically, you'll have to download and extract the package, install drivers if necessary, boot your device ...

In terminal emulator; Become root $ su List users to get their ID. It's the first number listed, usually 11 for the first user. 0 is owner.

The Mediaserver process scans your device for media files to add to your library. However, the 2012/12/12 (perhaps some more) gapps version is broken and gets stuck in an infinite loop on unfamiliar files on your phone. This directly translates to battery drain and is bad for the lifetime of your battery and other phone components. When running your phone ...

I have a Nexus 4 from T-Mobile, the Google one, with Android 4.2.2. I've been noticing this same problem, and the fix I found was to go to Settings -> Language and Input -> Then press the settings icon next to the Google Keyboard (English, U.S.) option -> then deselect Block offensive words. I can now swype swear words, although often times it is not the ...

Go into the People or Contacts app. At the top of the list is a heading Me with a special item to Set up my profile. Click that item and it takes you to the "New contact" screen. On this screen, to the right of the "name" field, there's a little grey "contact icon" box. If you click that you can replace the photo with a picture from the Gallery or by taking ...

I was testing ways to toggle the on-screen keyboard. In Android 4.2.2 on a Nexus 7 I had to go through the following steps to toggle the on-screen keyboard from the tablet while a Bluetooth keyboard is connected: To activate the "Choose Input Method" notification you need to have multiple keyboards available. On a stock Nexus 7 you can go into Settings then ...

Do you really want to do that? That might lead to you no more being able to see your images in the gallery. But if you want to try: open a file manager of your choice and navigate to the DCIM folder delete the .thumbnails directory create a file named .thumbnails open the file's properties, and set it "read only" Now, as there cannot be two objects with ...

I recently came across this issue on a Nexus 5 and tried most the solutions listed here with no luck. In my case, it looks to be caused by a recognized bug with stock Android (source). My solution was as follows - I used Windows 8.1, but no reason this wouldn't work on OSX/Linux (root is required on device however). On your PC, create a .tar.gz archive of ...

This menu button is a backwards compatibility feature. It's displayed on all apps that say they are designed for a version of Android from when Android devices had physical menu buttons. (That's Froyo or earlier.) The Android system can't tell whether such an app needs the menu button or not, so it has to display it to make sure the app is usable on newer ...

I can confirm that this is normal behaviour for the default (blue) Google Calendar on the Nexus 4 - just the 1 app. Having tried a few tests of my own... The multiple "roll-up" events appear to be events for which you have already received a notification, but have not explicitly acknowledged or "dismissed" it - in which case the notification remains in the ...

I have the same problem when sending encrypted mails from my Apple Mail client with GPGMail2 plug-in. Apparently K9-Mail supports only PGP/Inline and not PGP/MIME which seems to be the standard formatting PGP-Emails today. If you like to test it on your own, configure GPGMail to use inline mode through your Terminal: defaults write org.gpgtools.gpgmail ...

If your device is rooted, as it probably is with CM, you can also do this via adb: adb shell rm /data/misc/adb/adb_keys Depending on your build you probably have to run adb as root(1) or call the su binary(2). (1) adb root or adb kill-server; sudo $(which adb) start-server --> adb shell rm /data/misc/adb/adb_keys (2)adb shell --> su --> rm /data/misc/adb/...

No Android version natively supports IKEv2 yet. But you can install the free and open-source strongSwan VPN Client that uses IKEv2 and runs on Android 4 and newer.

I've never found Windows to be very helpful in identifying drivers either. Here's some information for you on what USB CDC is. According to Wikipedia: USB communications device class (or USB CDC) is a composite Universal Serial Bus device class. The class may include more than one interface, such as a custom control interface, data interface, audio, ...

One word: Vysor Using the vysor to control my Xperia Z2. See the state of my phone, but Vysor came to the rescue. *if phone reboots and won't connect after plugging in, try removing the micro sd card. Mine wouldn't work at all until I did so - random phone smasher

Looks like these days the best solution for controlling an Android phone from a PC is scrcpy. It is being actively maintained, has very high performance (framerate, latency), is available cross-platform. It also does not require root on the phone.

In 4.2.x Jelly Bean you can pinch-zoom or two-finger glide in order to toggle between base and expanded [notification] layouts. Not all notifications can be expanded, however. The next time the notification appears try using two fingers to "pull" the notification down into an expanded layout.

No. A system app has to be either installed by root or signed with the same key that signed the ROM image.

Create an animation script (text) file as desc.txt with the following content: 240 320 24 p 1 0 part0 Explanation: In first line 240 320 24, 240 320 is the device's resolution and 24 is the frames per second. Higher the number, faster the animation. In second line p 1 0 part0, p is a code to tell it to look at new commands, 1 is the number of times ...
