There are several factors. No carrier or manufacturer bloatware. If you want to test apps or OS changes and be sure you're not hitting some device-specific bug, a Nexus device makes it less likely that will happen. They all use the same tool for flashing ROMs: fastboot. Not all third-party devices use it, and having to learn a new set of commands for every ...

The before and after screenshots of the about screen confirm that I had the exact same Android, Baseband, and Kernel versions, as well as the same Build Number Actually, they do not. The first screenshot shows a build number of JWR66V, and the second is JWR66Y. An official changelog has not been released, but T-Mobile's documentation indicates that the ...

It sounds like the "/system/bin/app_process" has been modified and so it doesn't match the signature required. There are 2 ways to fix this, either get a copy of the stock file from another phone/rom or flash the factory image for 4.3 Edit: After reading "update 2" it sounds like you want the factory image option detailed below. ...

Did you backup/restore your settings to/from Google? If so, that's why you can connect to these wireless networks. One of the things that gets backed up is the wireless network passwords so when you restored them back on your new device it is able to connect. Android has built in backup functionality. It offers to backup settings (including wifi settings) ...

Your current layout is called "Material Light". To change it, though there isn't a pure black version, go to Settings > Language and Input > Google Keyboard > Appearance and Layouts The dark material setting is called "Material Dark" and looks like this: I'm assuming you want material design as you are keeping it stock, but there are the old KitKat '...

Go to Settings >> Security >> Device Administrators. See if anything other than Android Device Manager is checked. If something is checked, it's possible it's forcing a higher level of security. Uncheck it if there is, and check the screen lock options again. Also try Settings >> Security >> Clear credentials.

Yes. Locking the bootloader is possible after you have installed a custom firmware. A locked bootloader will not allow you to ad-hoc boot custom binaries (using fastboot boot boot.img and will not allow you to directly write to the flash chips. An unlocked bootloader however does offer you this and newly available commands are: fastboot flash partition ...

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 ...

It's not enough to make the Developer options page appear in the settings menu (by repeatedly tapping the build number). On that page, there's an option USB debugging, which defaults to off. When USB Debugging is enabled, connecting your device to a PC using USB makes the "USB debugging connected" notification appear, regardless of whether adb is currently ...

Compared to Nexus 5, Lollipop stock launcher on Nexus 4 doesn't have transparency on the notification bar. Instead, the one with transparency is Google Now Launcher (originally known as Google Experience Launcher). After installing the launcher, you can switch between those two from Settings > Home.

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 ...

Most of these permissions are used by Google Now and the new features they will be bringing out after Google I/O and the upcoming Android L Release. I'm not sure about why they need a lot of these permissions, but I will explain the ones that I know about. Feel free to edit the answer to improve it. I have listed all the sub permissions as listed in the ...

The Nexus Root Toolkit is the way to go, tho note that to unlock the bootloader, you will have to wipe your device. However, you'll only have to do this once, so when Google's next update removes your root priveleges, you can just run the Root utility in the toolkit. If the toolkit can't reboot your Nexus 4 into the bootloader, you can do it manually with ...

If every app had to interpret the raw GPS input itself, it would be very silly. Different apps would duplicate the same effort of decoding and interpreting the GPS input to compute a location. Different apps would end up using different libraries to do it, so each app might end up with a different idea of your location. Instead, the process of interpreting ...

The Exploit (& Fix) Android "Master Key" article describes the process of using the “Master Key” exploit to get elevated privileges with lots of technical details. The main point is that the exploit by itself does not give root privileges — only arbitrary code execution as the system user, and another privilege elevation exploit is needed to get root ...

This is a famous issue affecting USB file access over MTP. I can't even remember how many hours I've lost trying to access files created by my first app on a PC (and I'm talking about GBs of important files). If you start the app and it creates the folder, then you have to reboot the device in order to let your PC be able to correctly display the folder. ...

With the backing of dotVezz, summing up from the comments: Considering the specifications, this is quite unlikely: range of the NFC signal is limited to a max of 10 cm on "clear view" (see Wikipedia) material with a greater density will reduce this even more: air ~ 0.001 g/cm3 versus Lithium ~ 0.53 g/cm3 makes rawly a 500-times-density difference, so a ...

Most phones use data downloaded from the cell network to speed up the initial position fix when you turn on GPS: without these data, it can take several minutes to first get the position, as the GPS receiver has to download all the ephemeris data (i.e. the latest updates/corrections about the satellites' orbits) via the low-bandwidth GPS connection. Using ...

It doesn't seem unusual to me that an app that commercially depends on tracking its users would send you to a website to track and count you, and then have that site redirect you to the real store page. If you don't trust them not to misuse this tracking data, don't use the app.

I had this problem trying to push back a backup of my Samsung Galaxy S2, using ADB with the CWM (clockworkmod) recovery tool. When pushing to a device file, ADB simply deletes the block device file and creates a regular file in its place, and thus no data actually ends up on the mmcblk0 device. Unfortunately, piping the output of a command into "adb shell" ...

I think the first answer (by June Lau) misses the point - the question was about sharing files between different users on the SAME device. I have been using subdirectories that I created within android/obb with success. In my Nexus 7 tablet the exact path is /storage/emulated/0/Android/obb/. The issue is that the media browser does not see files in there, so ...

There are two ways you can upgrade your device to a latest version of OS: OTA (Over The Air): This type of upgrade will automatically take care of all the steps required to update your system. The once which you are bugged with is OTA update. One needn't erase data while upgrading using an OTA. Flashing your device: Usually Google releases device specific ...

As mentioned in another answer, on devices that use FUSE for SD card emulation (such as modern Nexus devices), only root can change timestamps of files in /sdcard. Since things like MTP and ADB don't run as root, you can't preserve the timestamps with these methods. However, if your device is rooted, you can fix the timestamps with a separate step ...

So I've had this same problem for the past month. There is a 1cm or so high deadzone that spans the width of my screen just about lower than the midway point from top to bottom. It is mostly always there, but some (seemingly) random times it goes away and all works well. My troubleshooting led me to this: If it's hardware, it's only because the software ...

It depends on the launcher. Most stock launchers won't, but I know Nova Launcher (only Prime version) has folders in the App Drawer. It's all manually done, though. Other launchers, which I can't name right now, can probably organize it for you.

No, it will not update Google Maps. You will have to update that manually or through Google Play. However, after you download and install the OTA update, you may receive a Google Map update notification. Just make sure you don't set your Google Play apps to auto-update, so you can close / ignore those notifications. Source: Comments on CNet.
