Check your memory card alignment and if its properly seated. If its a loose contact, your phone will definitely restart.

Samsung Messenger Alarm Problem


I have this problem with my MetroPCS Messenger R450. I called Samsung, suffered through the person on the other end who was sooo knowledgeable he didn't know what a "hyphen" was, and finally got it through to him that my alarms didn't work and he issued an RMA. I expect the box here in a day or two. Only price so far: dealing with the idiot on the other end of the phone.
