Screen Brightness Issues..

---

After long consideration I decided 2day finally update my (amazing) Galaxy Tab 7 to the new 7.7. I saw 5 units in hand but they all suffer from a screen issue. Even with Auto-Brightness OFF, when displaying bright images or there are large portions of white, the screen always self-dimms. I tried all possible settings, all units the same.. nothing 2do w/settings or the ambient-light sensor.. its the nature of this Tab. Ad a real-world test I tried displaying a small white square in the center of the screen w/maximum brigtness and as I enlarge the image the whole screen darkens progressively. By the time the image is in full screen (all white) brightness is less than 1/2..

Is this a hardware/ software issue? Has everyone else noticed this? Is there a fix? Its an absurd flaw.. needless to say, Im not buying the 7.7 till there is a remedy for this behaviour..

Under settings disable automatic screen power adjustment.

Thank you. That makes sense because its under full white that AMOLED screens use more power. Where is that setting? Im used to Gingerbread.. Honeycomb is a mess, I cant find anything I wanna get to

Thanks again

Settings > Display

Its a tick box I cant recall exactly where it is but I think its like 2-3 options under screen brightness.

Though you have to take note that the white levels on the Tab7.7 are lower than compared to the 8.9, 10.1 and almost all other high-end Galaxy phones.
