I have a nokia E90 that does not "see" when the lid is closed any more.
Both displays are functional, but the phone only uses the internal display, it does not recognize when I close or open it.
Does any one know how the phone detects the opening and closing of the internal display ? For sure there is an internal switch or something like that but I have open the phone and can't figure out where is the broken piece.
Hey Altexandru, Welcome to the Nokia Forums!
As Farby above stated, conversation regarding self servicing of device hardware is not permitted as it can cause more harm to your device than good and can also void any existing warranty.
If you are experiencing problems with your device's hardware, I suggest that you take it to your nearest Nokia Care point to be repaired by an expert.
I hope this has helped!
