I don't know what happened with my phone, but after a while it started freezing and restarting all the time and sometimes even a blue screen would come out and stay frozen like that. I have took such good care of this phone cus I really love it, but I been having this problem for the last 2 days and the weird thing is that it seemed to happen always around night time. Any suggestions? I tried resetting and factory resetting and unrooting and very thing, but it came back.
