I am going to rebump this topic because i just got a new phone Note 4 N910u on 5.0.1 and my bluetooth keeps disconnecting.. randomly .. and i dont know what to do.. anyone got any ideas. that i haven't already tried. i got to fix this issue on my note 2, but i tried that idea but it didn't work.. when the screen turns off. the bluetooth disconnects and the bluetooth is left in discover forever. and standby wifi is off. this fixed the issue on my note2. but now i can't seem to fix this issue on my note 4.
