My LG G4 time zone keeps reverting to GMT when I have the "Auto-date & time" and "Auto-time zone" settings checked (I am in downtown Portland, OR). If I uncheck and recheck the "Auto-date time" setting, it will usually reset things back to the correct setting but then, within15-30 minutes or so, it switches back to GMT again. It has happened 5 times just today. There doesn't seem to be any pattern to what triggers the switch.
For now, I have set the time zone manually to my desired location but that's not going to work if I happen to be traveling.
Is anyone else seeing this kind of behavior?
