Screen drifting?

root

 

edit build prop

 find "ro.sf.lcd_density=***""

add "view.touch_slop=XX" (XX is 01~30 and means the sensitivity of touch screen, the bigger the more sensitive.)

 

 to avoid the affect of static electricity, use number below 15.

 

then save, quit, restart.

 

 

Now still in testing.............
