Google has finally started rolling out the Android 4.2.2 update for the Galaxy Nexus, Nexus 7 and the Nexus 10. The .1 bump in the Android OS version denotes some under the hood bug-fixes from Google, mainly related to the broken Bluetooth stack that was introduced in Android 4.1.1.
The update also bumps the Android build number to JDQ39. As of now, only Galaxy Nexus, Nexus 7 and Nexus 10 owners have got the OTA update. There is no confirmation from Google whether the Nexus 4 will get the OTA update or not.
Early report suggests that the Bluetooth streaming works better now, but it is still not perfect. The OTA update also includes a new radio/modem for the Galaxy Nexus that may or may not bring about an improvement in network reception and power consumption.
