Didn't see a thread just on bluetooth for Nexus 7 so started this one. Sorry if duplicates issue found elsewhere. the Nexus 7 bluetooth is very unstable and almost unusable. It turns off automatically without notice and once that has happened every time you try to start it again it turns off again in a few seconds. It has happened when I tried to use hands free in the car and when I tried to use an Anker Bluetooth Keyboard. I have the latest 4.42 upgrade. Is this an OS issue or is it hardware? This urgently needs to be fixed. It makes it unusable in the car and for editing documents (without bluetooth keyboard).
