Updated my samsung mesmerize to 2.3 then the problems started. When I'm listening to my music player (stock and Dtwist) the music player will start skipping and goes back a screen and sometimes the phone will just shut off. I also notice everything gets laggy with phone. I've tried everything I can think of to fix this problem. Keeping memory clear, uninstall all downloaded programs even a factory reset. I've ask at the US cellular store but no one seems to of come across this problem. It seems to start while I'm playing music in my truck and I hit a bump but not always, sometimes it just starts doing it. Like I said I've tried many things but no success. Hoping someone has more suggestions to try to fix this. Everything worked great in 2.2.
