Android 10: solutions.

[instasck]

I am facing "could not open /dev/input/event3, Permission denied" on android 10.

I know there is a solution with SFT here, what I want to ask is:
As far as I know inject inputs from "InputManager" is not the same as direct touch screen.
The main different is that each touch report pysicalId==0 which is detectable from app side as not a real touch HW.

I want to ask- is it the same as adb input tap 0,0 ?

Another solution:
Switch to root
chmod permissions
switch back to unroot.
Will this work ?
