Hi Guys I had simmilar problems and I have A5C8 so here are my numbers
after updating Windows 10. This should work on all versions of X98 tablets using same screen
Put the attached ‘TouchSetting.gt’ file (from upper post) into C:\Windows\INF folder and reboot
Changes I have made to the standard touchsetting file are
UpdateCFG=1
ESD=0
X2X=0
Y2y=0
X2y=0
NumberOfKey=1
And also I had same binary key
LAST THE MOST IMPORTANT was in CONTROL PANEL > TABLET PC SETTINGS > CALIBRATE!!!
