* What's the phone touch sampling rate? Also called as the touch refresh rate, the sampling rate can be defined as the number of times a touchscreen can sense input from your finger in a second. * How does touch sampling rate matter for your phone? Now that you know what exactly is the touch sampling rate, you might be wondering how does it affect your experience. For starters, it is directly proportional to the responsiveness of your touchscreen. The higher the number, the better the speed and lesser the touch lag. When the screen refresh rate and touch sample rate are the same, say 60Hz as it’s for most phones, both the tracking and refresh intervals happen at the same time at 16.6ms. And this delays the rendering of the animation by one interval. However, if the sampling frequency for the same panel is increased to 120Hz, it’ll track your touch faster (8.3ms) than the time display takes to refresh. This will allow starting rendering the next frame in time for the very next screen update. Whereas if they were both at the same rate, you’d have to wait for the next refresh cycle....
