    For about 2 months , my g3 has been restarting randomly on its own. I did a factory reset, but did not help. I took it to the store and they couldn't figure it out. I called T-Mobile and they sent a new phone under warranty. I took it in store to have my stuff put on the new phone from old phone. As soon as it started, it shutdown many times on its own. They didn't know what to do  since it was happening with a different phone. They ordered me a battery to try that. I put it in and it still restarts with the new battery and new phone. What would cause this? And what else can I do?
