Android 4.2 on Nexus 7 has broken Bluetooth, users complain

Android 4.2 Jelly Bean looks to have a flaw when it comes to Bluetooth communication.

Android 4.2 Jelly Bean looks to have a fatal flaw, if reports from irate Android fans are to be believed. It seems the spangly new software struggles to cope with Bluetooth, and stutters during music playback.

That's bad news if you have a portable Bluetooth speaker or use the wireless tech in the car while driving. One person writes in Google's coding forum, "When I stream music from my Nexus 7 to my Bluetooth speaker system it is stuttering every few seconds -- unusable."

Another says, "This is happening on my Nexus 7 as well. Very disappointed," while one glumly notes, "I may just return this Nexus as I just bought it and get an iPad." Meanwhile, on the XDA Developers forum, a Nexus 7 owner says, "I am highly disappointed in Google for this."

The Nexus 7 is mentioned frequently in the forum, but there are other devices running Android 4.2 or about to be running Android 4.2 -- namely the Samsung Galaxy Nexus, the Google Nexus 4 and Nexus 10.

Our in-office Nexus 7 hasn't received the update to Android 4.2 yet, so we can't verify the glitch -- but if you have an Android device running the latest version, let us know if Bluetooth playback is working for you by dropping us a note in the comments or on our Facebook wall.

Some commenters' posts suggest the issue could be connected to Wi-Fi, while many report the issue wasn't present in previous versions of Android.

It seems glitches are common with new software or gadgets these days -- hands up if you remember the Galaxy Nexus' bizarre volume-dropping bug? They tend to be ironed out before too long, but that doesn't make them any less frustrating for customers, and doubly grating if you're one of the dedicated few who installed the new update at the first opportunity.

Android 4.2 is the very latest version of Android, and brings new features such as Photo Sphere and multiple users on tablets.

Have you spied any Bluetooth woes with your Android kit? Is it not behaving properly? 

Update 16 November: CNET reader George Taylor emailed in to report that, after updating to Android 4.2, his Nexus 7 no longer connects with his Bluetooth mouse, which had worked "perfectly" with Android 4.1. Anyone else had similar peripheral problems?
