This does not necessarily mean your phone is dead. Your phone will flash the red LED light briefly when the battery is completely drained. When I got this I left the phone in the charger for a while, and eventually the white "charging battery" icon appeared again. Upon turning on the device it had 0% battery. It was in fact so drained that it died while on ...

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 ...

Recommended lecture: Why did /sdcard/ turn into /sdcard/0/ with 4.2?. In short: It has to do with the multi-user functionality introduced with Jelly Bean: /storage/emulated/0/: to my knowledge, this refers to the "emulated MMC" ("owner part"). Usually this is the internal one. The "0" stands for the user here, "0" is the first user aka device-owner. If you ...

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. AndroidPolice has a step by ...

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) ...

You don't need any special drivers -- all you need is to make your device known. A few simple steps can accomplish this when your device is connected via USB: sudo lsusb [...] Bus 002 Device 054: ID 18d1:4e22 Google Inc. Nexus S (debug) See the two hex values separated by a colon: 18d1:4e22 This is the manufacturerID:deviceID you need to tell the system to ...

Yes - all android devices will work without a SIM card, and can be connected to wifi for an internet connection. EDIT: Just so people know, there is a setting in the build.prop file that determines whether or the not the device can be used without a SIM or not. Most of the time this is set to allow it, however in rare cases it may be disallowed.

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 '...

You can't, this is a current permission problem (bugreport here) of Android 4.0+'s /sdcard folder if it's not using FAT32 (but FUSE). Reason: There's a transition away from FAT32 to unified user storage for both apps and media data (using ext4) on a single file system. We got tired of seeing OEMs include many GB of internal storage for music, while users ...

This is a known issue (or feature) in Android 4.2, and there's probably no fix for now. UPDATE 2013-12-10: According to Marius Hofert, it is still an issue in 4.4.

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.

Seeing a file name like Computer\Nexus 4\Internal storage\Music\Christina St眉rmer\Freier Fall\1 Geh nicht wenn du kommst.mp3 points to a special problem with "special characters" (such as German Umlauts) which got messed up on data transfer: While Windoze uses its own character set (MS-ANSI or wone of the WIN-12xx, depending on configuration), Android ...

Sometimes you have to activate the Trust Agent: Settings -> Security -> Trust Agents -> enable Smart Lock

It should be under your system settings (the Settings "app"), in the "Date & Time" subsection (which is near the bottom). Uncheck the "Automatic time zone" option and then select the correct one manually:

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 ...

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 ...

I just saw it. It was a simple case of 100% discharged. To fix it use the power socket charger and not the usb charger from your laptop or desktop. The red light first goes down, then it will blink and then the white charging icon comes. Let it charge at least 10 minutes after that before you switch it on, otherwise it would shutdown again (but won't go to ...

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. Lollipop stock launcher Lollipop Google Now ...

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 ...

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 ...

Some Android devices, mostly older ones, and CDMA2000 devices, will attempt to let you not use them without activation. Usually the 'provision' application has a secret code that can bypass the 'mandatory' activation - e.g., on the Motorola Droid 2 Global it's upper left corner, upper right corner, lower right corner, lower left corner (the lower corners ...

Yes, it has HSPA+ which is what T-Mobile's "4G" actually stands for. This article on AndroidAuthority should help you understanding why it doesn't have LTE.

It would be a wast of time (and money). The phone is not compatible with Verizon's network. Verizon is a CDMA network, and the Nexus 4 from Google is GSM phone. In the past Google has met-in-the-middle with Verizon and released the CDMA compatible Galaxy Nexus - this time there appear to be no plans on releasing a CDMA compatible Nexus 4 (possibly due to ...

The Specs at GSMArena mention TV-out (via MHL A/V link), which suggests it should work. On the other hand, ExpertsReview states: The micro USB port also doubles up as a display output, though surprisingly it doesn't use the MHL standard that we've seen on numerous recent devices, such as the Samsung Galaxy S3. Instead it supports the new SlimPort ...

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 ...
