Hi all sifus,
I am having a bluetooth disconnection problem with my note 2. With the same earphone connect to another phone, there is no problem. But with Note 2, the connection will drop after ~30s, even though it is in the mid of streaming some audio to the earphone. I had played around with the "call audio" & "media audio" (under bluetooth setting) but still could not solve the problem. After disconnection, the phone will try to reconnect but the connection will not get through unless I disable the earphone and reactivate back.

By the way, I am using stock rom with chenglu root. Thanks for any input.
