Hi, Recently I bought one superpad III tablet, and I was trying to change brightness, there was an option called 'power control', I pressed that button and screen gone to black. I am unable to get back to the original display. Whenever I switch on my tablet, penguin logo followed by 'android' message and green man are displaying. After that black display is coming, whenever I touch middle down, small vibration comes. I googled a lot and found some solutions like 'use reset button','home+power+black(back)','home+menu' but none of these worked. Please help to get rid off the black screen. I have used my tablet only 2 hrs.
