Hello, I just started seeing this yesterday afternoon -- when the screen is locked/on power save, it will randomly turn itself back on. THe phone is still locked, but this will occur every few seconds to 30-60 secs. Then it will just black out again to being screen locked.
I haven't installed any apps lately. Was there are new system update? I don't recall seeing any. I've restarted the phone a few times already, also by removing the battery.
Also, the day prior I noticed all my photo tags were erased. not sure if it's related. ugh
