I have already commented in another post .. Do not do the ITO test or the screen will stop working .. I am not the only case that has happened. Even I have not solved .. I need help from a developer who knows how the calibration of the screen works.
I did the same mistake yesterday... Now Mi Pad 4+ reacts very slow. Don´t know how to fix this so I hope anybody from this forum found a working solution. Please, need help. My device is actually not useable. Check my screenshot. Left side of the screen doesn´t solve the test. Please help me!
