Maybe your hand is momentarily blocking the light? If so, maybe the automatic brightness code should wait for any dimming to (a) persist for longer (e.g. 4 seconds) or (b) to be less volatile (e.g. turning off a light switch results in less-volatile dimming than moving your hand over the phone does).
