Last night I woke up and my phones screen was on the 4G LTE startup. I let my dog out and when I came back in the room I saw a flash of light. I think it was the rings on the 4G screen. I then did a battery pull and it got stuck there again. I then did another battery pull and it stayed on the 4G LTE screen for 3 minutes before it went on to its normal business ( It did not dim the screen or have the rings going out). Has anyone ever had this happen to them? I was worried I was going to have to do a hard reset or something on it. It happened again! Last night I woke up around 2 am. My phone was stuck at the 4g logo startup. I sat there hoping it would just boot up normal. I watched it restart itself 3 times before I took it out of the dock. It restarts and when it gets to the 4g logo it just sits there for 2-3 minutes and then restarts itself. Once I took it out of the dock I thought I would see if it would correct itself since it wasn't charging. I let it restart 2 more times and nothing. So I did a battery pull and waited 30 seconds to put it back in. That did it but I cannot have my phone restarting in the middle of the night and getting stuck like that. I use my phone as my alarm clock. Has anyone had this happen to them? What is wrong with my phone? I have done a factory reset since it did it before. It seemed like since the incident first happened my gps was not working. I use it for running and it would never find a signal. I haven't updated google maps thinking that was it.
