So on Sunday I got a retail g6 from Verizon. About an hour ago it randomly turned off and then displayed the "device is corrupted and cannot be trusted message." It then proceeded to say startup failed and turned off again and wouldn't turn back on. After freaking out some I saw something online about trying to use the volume keys with the power key to reboot. So I held the volume down with the power button and my phone restarted like normal. Absolutely no issues or lag. I decided to restart my device to see if the message would display again, but my phone restarted as normal. All of my apps and data are there as normal. I read that this is an Android issue, not lg. But I also saw that usually the phone doesn't decide to just start working normally again. Should I be concerned?
