Hello again,
My touch problem fixed after do this:
1. Get the drivers in http://techtablets.com/chuwi-vi10/downloads/
2. Open Control Panel > Device manager
3. Remove devices below:
Sensor > BMA2x2
Human Interface Devices > GPIO Button Driver(Name may not exactly same, whatever)
KMDF HID Minidriver for Touch I2C Device
4. Get the Double Driver : http://double-driver.en.softonic.com/
5. Open the properties tab of dd.exe from the Double Driver package and do below steps:
Compatibility > Compatibility Mode > Check “Run this program in…” > Set mode to “Windows XP(Service Pack 3)”
Check “Run this program as an administrator” in Privilege Level
6. Execute dd.exe and do below steps:
Restore > Locate Backup > Other Location > Select path of driver files(Step #1) > OK
Select > None (Uncheck all drivers)
Check “KDMF HID Minidriver…”, “BMA 2×2…”, and “GPIO Controller” > Restore Now
7. Then Double Driver will install the driver properly and your touch location will be fixed.
Let me know if you have any questions.
