I solved the problem by accident.
I contacted by email pipo the only answer was to change the touchscreen: twisted :: twisted :: twisted:
I installed all kinds of firms m9pro stock, customs and still the same problem http://www.youtube.com/watch?v=5TPv_...ature=youtu.be.
Suddenly I started to experiment I installed m8hd firm of m9 until I came across this post http://tablette-chinoise.net/problem...een-m7-pro-no- 3g t4502 or the person said Pipo made it a firmware to fix the problem and I thought why not.
Install "update # 80_M7pro-892-20131211-no-quickboot.img" ROM_Flash_Tool_137.exe with black screen.
Always ROM_Flash_Tool_137.exe nand erase 3times.
Then I installed the ROM "Pipo_M9_Pro_RileyROM_2.1".
Here is the result http://www.youtube.com/watch?v=U_2rF...ature=youtu.be

Glad you got it fixed.

Funny things happen when flashing ROM's. All it takes is one little hiccup in the USB connection, or something that will cause huge problems. Many times, I've had to go all the way back to the first ROM to get back to normal.
