I just upgraded my S4 with the "update_SCH-I545_MI1_to_MJ7" patch and now bluetooth audio will not work properly. I have several bluetooth headphones and speakers and the issue affects all of them. I can connect and play one song if I start the song from the S4 and not through bluetooth controls. However after one song it stops working. I have to disconnect and reconnect to play a second song and then it breaks after that.
Obviously there is some bugs in this latest upgrade. Is this a known issue and if so when is a fix anticipated?
