Hello, I have the Prime version of the Note 2. I've been on various weekly ROM versions from 5.10.15 onwards (now at 5.11.1) and I'm having trouble with bluetooth in all of them. After some period of time, bluetooth cannot be activated anymore. I have yet to see a pattern to this, but it usually happens every couple of day. When I try to turn it on, it turns itself off again right aways. Only a reboot fixes this. This could be anything from hardware, ROM, conflicting app... if any other users run into this, please share.
