Hello friends. Recently, I purchased an N79. It is really a nice phone fulfilling all my requirements. But unfortunately, some days ago I met with a serious road accident in which I hurt myself to some extent. In the accident, my handset's display underwent a crack which really ripped my heart. Since accident cases are considered by Nokia, I could not utilize the advantage of the warranty. So I spent some extra bucks & got it replaced from the Nokia Care Center. This made the warranty to expire. N79 has a feature of flipping the display (a.k.a. the motion sensor) which worked fine before. Even after the accident, it worked for sometime, but it has suddenly stopped working. When I asked in the same Care Center, they say that the accident might've damaged the sensor. But the sensor works fine when I reset the handset & even when I activate the camera. On activating the camera, the screen flips, & returns to normal when the camera is deactivated. If I flip it later in the normal mode (not in camera mode), it does not work. After resetting the device, I mean, when I restore the factory settings. it works for 2-3 days then again stops working. What might be the problem? If there is anything that can be done, please help me out.
