I'm new on this forum, I read it several times and I find it very interesting!
Hope you can help me with the problem that occurred on the phone a few days ...
Usually hold the screen in auto brightness mode. When I am near a source of light, brightness increases, but when I leave the area bright the screen should change his intensity, but he remains the same, at high brightness. Brightness decreases and becomes what it should be according to automatic mode only after lock-unlock screen.
Battery not lasting as it should because of problems with the screen.
It is a light sensor problem?
The phone has done the ICS update.
Thank you very much for your help!
