My Samsung Acclaim keeps shutting off on me, I have to then pull the battery to turn it back on! ANNOYING! US Cellular wants me to bring it in for a new one- however apps won't transfer over to the new phone- This is gonna drive me nuts! It has shut off for about the last 3 out of 5 days. Battery life is fine, fully charged. Unsure as to why it keeps shutting off. And I can't just turn it back on I have to pull the battery. Anyone else have this problem?
