Re: screen dimms

The screen will dim depending on the room brightness. There is a light sensor next to the front camera. If you place your thumb over this sensor for about 20 seconds, you should notice the screen brightness change. Make sure you are not covering it.

I think your covering the light sensor or your screen guard is not of a good quality.

I've got a similar problem with my new PlayBook when automatic backlight dimming is turned on:

When swiping from anywhere on the bottom half of the screen across the touch sensitive bezel the screen dims and turns bright again directly afterwards. The same applies when I make a swipe gesture in the bottom left corner and don't cross the bezel while doing so.

OS is installed.
