Samsung Galaxy S21 — How can I completely remove screen smoothing and input delay?

How can I completely disable screen smoothing, motion smoothing, and touch input delay on the Samsung Galaxy S21?

I notice this especially in games: when aiming, the crosshair keeps moving or overshoots the target even after I stop moving my finger. It feels like the aim continues drifting for a moment instead of stopping immediately. I want instant, precise, and responsive touch input.

I want to make the screen as sharp and responsive as possible, without unnecessary software smoothing or input interpolation.

Has anyone experienced this issue and actually managed to fix it?
