The Android 4.2 was launched several weeks ago and since there were some problems with it, Google decided to launch a new firmware update before December comes. That’s why the Android 4.2.1 firmware was released and it comes with several improvements and some bugs and errors have been fixed.
This update has been pushed as an Over-The-Air Notification and it only measures 1.1 MB, which means that there are too many new features. It brings fixes and improvements over the former Android 4.2 and it seems like the annoying December bug has been removed. Also, the bluetooth errors and problems have been resolved so you shouldn’t find them anymore on your Nexus 4.
The USB On-the-go has not been fixed but, if you’re a user that wants to use such tool, then you can fix it using a custom kernel. However, the new update has been pushed as an OTA notification and you will be able to receive this only if you’re Nexus 4 is running on Stock Android 4.2 Firmware.
Check to see if this OTA Jelly Bean 4.2.1 is available for your device by opening Settings, then About Phone and tap on the System Updates section to verify the availability. However, if you don’t want to wait for the official notification, then you can use our own guide HERE to manually flash the new OTA firmware update.
The International variant of Google Nexus 4 is the only model that can be updated using the Android 4.2.1 Update files. Note that some reports have said that this OTA Firmware Update can be installed only over Wi-Fi. At the moment, it has been confirmed that Germany, UK and some other European Countries. The United States devices still didn’t receive the push notifications.
Since the previous Android 4.2 had some errors and it seemed like not a complete OS, and with the release of this new OTA update that solves the December bug we can only hope that Google will launch a new firmware that really needs to contain new features and possibly support for USB OTG.
