I performed a factory reset a couple days ago, hoping it would fix the problem. I even consulted a support working in a live chat on Samsung.com, and they recommended the factory reset. The reset did not fix the problem. My phone still restarts a number of times throughout the day. It even turns off to where the power button doesn't work, and I have to take out the battery and put it back in just to turn the phone on. I'm hoping someone here can help me.
