    Every time I unlock my phone, a red light flashes at the right of the Nokia logo (maybe a sensor). I don't know why, can someone tell me what does it do?

    Probably the proximity sensor.

    Probably the proximity sensor.
    Should it light when I unlock? Also when I change the brightness to Automatic it lights up.

    Can't promise anything, but it may just be checking to make sure you didn't somehow pocket-unlock. I'm not seeing that behavior on my 640 though.

    I see a flashing red light on my 640, on the right side if the front camera, but not when unlocking its when the screen is off
