I've had my Motorola Rival cell phone for some time now, and it was working fine when I first got it. No glitches, no freezes; everything was good about it. But now, it has a problem. It usually happens after I send a text message. When I close the slider on my phone, first, the screen goes black for a second, and then the Verizon sign comes up as if it was just turned on. The white side touch buttons turn off, and it was as if I'd just turned on the phone. It happens at completely random times, so I can't even bring it to the Verizon store to see if they can fix it, because I never know for sure when it's going to happen. My phone isn't very old- I've maybe had it for roughly 7 months. Is there any way to fix this problem? I've heard from forum websites that other people have had this "restarting" problem. Is there any way to fix this?
