Hi All Been reading this forum for a while but registered today as I'm having a problem which is doing my head in. I have Note 2 LTE N7105T. I was able to pair it fine with my Toyota Corolla's factory Multimedia unit and it worked great. However, after a few days the phone started disconnecting at random and would not hold the connection no matter what. I have tried with phone idle, streaming music, on call but no change and bluetooth will disconnect when it wants to. Also disconnections are totally random, from a few seconds to couple of minutes apart. I almost always get a message on car multimedia screen about phone disconnected, then auto connection failed and then phone connected. On handset the bluetooth icon keeps showing connected for a few seconds after disconnection and drops only if reconnection does not happen quickly enough, which it does on most occasions. I had 4.1.2 rooted firmware (basically stock, only rooted to allow Titanium backup and advanced features of Tasker to work) earlier and could not resolve this problem. I updated to latest 4.3 official firmware over this weekend. In this process, I formatted my MicroSD card, internal memory and wiped all user data/Dalvik etc. Basically to get the phone back in stock factory condition. However, the Bluetooth problem persists. My wife's unrooted S3 (4.1.2 stock firmware) connects just fine and works like a charm to the same multimedia unit so the problem has to be with my phone. I have tried everything I could find. Looked at kchahal's solution posted in this forum but I could not find bluetoothpbap.apk in /system/app/. There is only bluetooth.apk and bluetoothTest.apk. I have also tried Bluetooth Auto Connect app (https://play.google.com/store/apps/details?id=org.myklos.btautoconnect&hl=en) which also does not resolve the problem. It connects back the the car unit a little faster but does not prevent disconnections in the first place. Any suggestions what so ever to help me resolve this would be highly appreciated.
