The update is arriving over the air and while it’s not yet clear whether it brings much besides the usual bug fixes, one thing Google has promised is a Bluetooth A2DP audio streaming fix.
Weirdly no Nexus 4 users have yet reported to have seen the update arrive on their devices. There are a few screenshots to prove that, so this definitely seems legitimate. So if you have a Nexus device, check whether that update has arrived and don’t hesitate to let us know in the comments below.
