So I bought my son a Bionic. It is a great little phone for him, however, he recently started getting this notification on his device telling him to turn his device off. The notification symbol is a solid white circle with an exclamation mark in it. He got this notification a few weeks ago, several times in one day, then not for a while and then again, several times in one day. I have not seen or heard of anyone having this issue so I am looking to see if someone has an explanation. I have not done a factory reset yet, but I will if I can not resolve this issue. I have checked the device for spyware & ads so I am at the end of my knowledge in searching for a solution. I am saving the dreaded reset for last since he will lose his saved game data. Thanks for any and all help.
