I presently have a Samsung Caliber from Metro PCS and I have a problem with it. I’ve had it for about three months and recently it is been shutting and restarting itself at random moments. Also, when I press the start button to start it, it loads until it is about to turn on then restarts. Why is my Samsung Caliber from Metro PCS randomly shutting and restarting itself? Does this happen to anyone else? How can I fix it? I would really appreciate your assistance regarding this. Thanks in advance.
