I just got the phone 2 days ago and everything works fine except for the 3.5 mm jack. I plug it in to my car mp3 port and the music plays fine but the phone stops functioning. No physical buttons respond even the unlock. The only thing that works is sliding the phone open which gives me touch access to the music screen. The music screen functions fine but since the physical buttons don't work I can't escape from the music screen. I have to remove the battery for the phone to function normally again. Any ideas as to what this coul be?
