I bought a Coby Kyros MID8048 8" tablet. It was great. I bought 3 more! My screen is out of calibration and for the life of me I CANNOT remember how to get to the screen calibration utility! Can someone help me? I've searched the internet extensively and find threads where people are talking ABOUT the problem and what they do -inside- the app, but nowhere does anyone say HOW to get into the app! Please help! And thanks!
