Hi, dear friends. As I typed iin topic name, I installed some firmwares for my onda V819 and touchscreen is going mad. It sems that only works fine in totally square surface (not all the screen is usable), and I have to turn it everytime I need to touch in some places.

Does anybody have the same problem or know how to solve? I tried to format tablet several times but it didn´t help.

Thank you very much... 🙂
