When my device's screen went blank after one minute inactive or when I press shortly on the sart button, I was then unable to turn the screen back on.
Nu matter how many time I press the start button or for how long, the screen is still just blank. I have to resort to press the soft-reset button to turn the phone on again. It is just so stupid.
First I thought it was sleep mode cause the problem but even when I disable sleep mode, every now and then I still experience the same problem. If I just leave it as it is then my device will restrt itself eventually.
Any thought on this??
