I have a Nokia 5800 mobile set. However, when it goes to the standby mode and the screen light becomes off, the screen light will not come back when I touch the screen or I unlock the cell phone.
But, to bring the light back, I can follow the following path => setting >display > light sensor and change the scroll position ! Then the light comes back !
Have you all ever been faced to such problem? I do appreciate if anyone helps.
