HOW TOUCHSCREEN REPAIR WORKS?
Touchscreen repair takes 4 response time values from 4 parts of your touchscreen. 3 such samples are taken for better accuracy. Based on these values, the app calculates a reduced, uniform response time and applies it for the touchscreen on software side.
This is how the app repairs your touchscreen.
