Is anyone else having problems with their bluetooth not connecting and their lockscreen freezing? My bluetooth is paired with my car but it is not automatically connecting. I have to go into the settings each time and manually connect the audio. The other problem is the lockscreen. It was working fine the past few days but today it just started freezing and the only way to get into the phone was through the settings. This problem went away after I took the battery out, but I am worried after seeing this as a recurrent problem with some S3s. Does anyone have any advice on either of these problems?
