Galaxy Nexus, Nexus 7 and Nexus 10 tablets.
Google has released the Android 4.2.2 Jelly Bean update for several Nexus smartphones and tablets.
Users on both Reddit and Google+ confirmed that the system update alerts for Android 4.2.2 have started to appear on the GSM Galaxy Nexus smartphone, the Nexus 7 and the Nexus 10 tablets.
The updated Android version delivers improvements pertaining to both performance and stability for the devices. It's also expected to issue a fix for a problem relating to streaming audio.
During January, Google stated that some Nexus devices updated to Android 4.2 (except the Nexus 4) were affected by audio drop-outs when streaming audio through Bluetooth using the Advanced Audio Distribution Profile (A2DP) system. "We have fixed the A2DP streaming stutter problem," a representative said. "The next release should have the fix. Sorry about the problem."
This fragmentation is killing Android
Apple runs both sides of the court, hardware and software, so can control aspects of updates easily. Google controls both also, but only if you buy a NEXUS device (and possibly new Motorola's). If you bought a Samsung/HTC/Sony/etc manufactured or AT&T/Sprint/Verizon/etc branded phone then don't expect updates.
The hardware manufacturers and the cell providers WANT IT THIS WAY. Why should they do work to make your existing stuff better, when so many consumers will happily shell out $600 for essentially the same hardware with a new OS.
From a developer standpoint it sucks, from a customer standpoint its wrong, from an investor standpoint its gold. Guess where these companies priorities are?
There is an easy fix for anyone not on the latest and greatest that doesn't want to buy a new phone. AOSP / Cyanogen
