    Light Sensor in a dark room issue?

    I've noticed something and i'm wondering if anyone else has had this issue.

    I was laying in bed with the lights out talking on the phone the past 2 nights. Each time i moved the phone away from my head to put the call on speaker so i could look something up on the phone.. Well when i move it away from my head the screen lights up for a split second then turns off. After a couple seconds it will either flash on/off again or stay on.

    It seems like the light sensor is confused and doesn't know if it's against my head or not during the call because the room is so dark. I have the automatic brightness turned off btw.

    Has anyone else noticed this?

    The proximity sensor uses light to determine distance from face etc. with little light then sudden light from the display, the sensor is just try recalculate distance (and sometimes it is wrong) and this is what you are noticing.

    If the problem occurs during normal to low lighting, then there maybe a problem.

    That makes sense, i kinda figured that. It doesn't give me any issues unless it's pitch black in the room.
