1 problem..
When the screen is off, the red LED flashes continuously. But when the screen is switched on, the indicator stops flashing. When the screen is off, the phone does not go to deepsleep. What is it?
UPD.
Pocket mod. All good )) I turn off this mod.
Oh, I have forgot that.. I made some quick research, it's proximity sensor which is blinking. Disabling "Pocket mode" should get rid off the blinking and save battery. Good you found solution by yourself
