I have been having problems with.Bluetooth ever since the Verizon update to the Android V 4.3. It appears to have an app built in that is called Bluetooth share. The problem is that it shuts down at random, and it shuts down.when a Bluetooth device is disconnected. If I turn off bluetooth.and turn it back on, the app runs and my Bluetooth works fine. It seems to be specific to the Verizon upgrade as I have been in contact with other S3 owners on different carriers and they are not having this problem. It did start with the update as all was fine before. I have searched for a fix and have not found any help. Verizon support isn't able to help and blames everybody else. I have tried all the standard fixes, impairing repairing rebooting clearing cache etc.and none has helped. Anybody have any other ideas or work around to this problem? Will an upgrade to V.4.4 when it becomes available help?
