I have a Huawei Ascend II. It keeps restarting on its own. I don't usually notice it until all the lights come back on when it's turning back on. I'm curious if this is a defect or what I should do. I had a Huawei Ascend and it didn't do this. Since I'm with cricket, if I have a problem I pretty much just have to buy a new phone. Anyone have advice?
