Hi All,
I have this problem with my new Samsung Galaxy Tab 8.9 and Google couldn't help me with that. The thing is when it's in idle state it keeps turn on and off periodically the screen. Doing it every 5-10 minutes probably, usually 5 times in a row - turn on/off, turn on/off and 5 times like this.
I tried to unload apps, rebooting it.. nothing seems to help. Wi-fi, BT and GPS are all off.
Please help how to solve this.
Thanks!
