The following problem:
With sunny weather the tablet display is almost black. BUT if you change to +2EV magically everything can be seen so the problem is not on the tablets side. Of course you cannot do this +2 EV trick because the video looks like this then.

All this tablet display problems could easily be solved with a software gamma adjustment (or brithness change which does NOT affect the camera settings).

I dont know which solution is the easiest to implement but its 100% sure that the black picture is not because of tabletscreen limitations but only because of how the camera picture is displayed.

I cant see ANYTHING on my tablet during a sunny day so its not just the app, I cant see the main launcher icons, read email, or anything else.

If I turn + 2EV i can see everything - though its to bright on the video then

so the tablet CAN be brighter
