Without so much as an official announcement, Google has started rolling out Android 4.2.2 to several Nexus devices. So far, the latest flavor of Jelly Bean is heading to two Nexus tablets, the Nexus 7 (non-3G) and Nexus 10, as well as the Galaxy Nexus (takju).

So, what exactly does Android 4.2.2 (JDQ39) offer? The official changelog isn’t out yet, but here’s what some folks have reported.

  • More secured ADB
  • Bluetooth audio streaming bugs fix
  • Download notification now shows remaining time
  • You can toggle WiFi and Bluetooth on/off by long-pressing them in Quick Settings
  • Performance enhancements
  • New notification sounds (wireless charging and low battery)

The last bit seems to be destined for the Nexus 4, but oddly enough, Google’s latest flagship phone is yet to receive the Android 4.2.2 firmware.

Of course, the list above is far from complete. Nexus 10 owners have reported that the tablet is now running more stable. It looks like Google has fixed the random rebooting bug that’s plaguing the device. Another thing that users might experience on 4.2.2 is an improved battery life.
