An upcoming software update should be better news for Bluetooth on Android... right, Google?
I've complained before here about the unreliability of Bluetooth on my Android phone (http://sulia.com/channel/android/f/d2eea5b1-0571-4b8f-a484-3f9ba2da2ff0/): Sometimes I can't get a file transfer to work, sometimes I can't turn Bluetooth on at all.
A press release from the Bluetooth SIG suggests things will improve shortly, announcing "native support" for the wireless technology's low-power modes in the next version of Android: http://www.bluetooth.com/Pages/Press-Releases-Detail.aspx?ItemID=167
Some questions around the I/O exhibit space revealed another factor. Google has switched between a few different Bluetooth stacks over the years (which would explain why it worked better on older phones), and in Android 4.2 and in particular on the Nexus 4 it's "kind of busted," as one rep apologetically admitted.
