Just trying to figure out if my proximity sensor is working ok or not. During dialling or calls the screen does not blank. Changing the sensor settings (Settings>Phone>Sensor settings) does not seem to make any difference. Does your 5800 do the same?
I watched a youtube video where the user shows how his screen blanks as soon as the sensor is covered after dialling a number say. So I think this is how it should work. Or maybe this function changed with later firmware??
The phone has the latest firmware and was recently soft and hard reset.
Interested to hear from others who have the same phone and latest firmware to see if yours works the same. PLEASE no comments saying "take to Nokia Care" or "reinstall firmware" - they won't help.
Thank you for the tip about the ambient light, but it makes no difference to my phone.
Any 5800 xpress music users out there that can help me with this issue, comparing the function of your phone to mine please?
May be Hardware related and you will have to take it to Nokia care as suggested by pavilion_alex
... but I think it should work under any lighting condition. If it doesn't work in a complete dark room, its purpose (.. preventing accidental selection during a call) is lost...
Thanks Chanchan for confirming. Kudos.
