does anyone know where to find info about how fast the touch screen is,
or in another word, I want to know how much time CPU need to recognize
that the screen was touched?
by basic, screens have 60Hz refresh rates c/o GPU
you may check this under Developers Options
to enable: Settings → About tablet → Software info → tap Build number 7 times
go back to Settings then look for Developer options on last part 😉
cant find anything pointing to refresh rate in dev options, but I will accept that
it is 60 Hz.
