mobile

I use my phone regularly for navigation with waze. One thing that is really annoys me is that when it's really sunny and bright outside, the phone display dims down to minimum brightness level. Brightness doesn't change even if I touched the screen. If I cover up the (brightness sensor?) on the top left part of the phone, the screen is bright again.. It seems like diffuse sunlight is causing some sort of weird thing with that sensor. I tried to point a flashlight directly on the sensor and the display brightens like it should. Only when there is diffuse sunlight, it does this weird behavior. :(

Anyone else seen this?:confused:

EDIT: I am on 5.1 leaked soak test. I am pretty sure I had the same thing happen when on stock 5.0
