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. Plus, I use this as my alarm so I can't have it restarting in the middle of the night and getting stuck like that.
