Hi, I just got my ICOO D80W ultimate tablet and I'm facing some issues : 1. The screen brightness seems to be low. I have brightness set to full. 2. I tried to run the netflix app, but it seems to be very slow and the scrolling is very choppy. 3. I tried to run the skype app, and it seems I can chat but the video calls don't seem to work well. 4. Sound isn't very loud. Can some one please give me advice as to how I can fix these problems ? I looked up ICOO's site and it seems like there was a firmware upgrade from may 2012, I'm not sure how to upgrade teh firmware on these devices as I've never owned an android device before. Has anyone else faced these problems on ICOO or other AllWinner A10 based tablets ?
