1100 backlight always on - GSM-Forum

nasirahmed · 08-11-2007, 17:08

I have a Nokia 1100 which backlight always on. The phone works properly. Call & receive. Torchlight also works. The problem is that the backlight always on when I put the battery. For your information, it was never dropped in water.

Anyone have suggestions?
