MI2S touchscreen has a noticeable high latency and a low resolution (touch resolution) compared to all other middle and high-end touch devices. You can easily see it when using drawing apps or some others that need an accurate touch response. After doing some little tests I noticed that my four years old Samsung phone with superamoled display has a latency three/four times lower than my xiaomi (if you quickly draws lines with your finger with eg. Autodesk sketch app with MI2S you can see that only a part of the lines are drawn on the canvas and they are drawn with a very high delay of about 0.3 seconds while the other touchscreens I tried draws every line traced and with no noticeable delays).The same happens with touch resolution, my old Samsung has an accuracy of about less than 1 millimeter while Mi2S has about 3 or 4 millimeters (you can't draw a point with MI2S without doing a short line with your finger) and also the sensibility of the touch is worst in xiaomi. These issues cannot be seen easily while moving on menu or using the keyboard but makes some apps unusable due to the bad touch response. My test are made with recent MIUI, but those are things that usually can be solved with a better touch driver or with a better calibration in driver configuration files (assumed that the touch hardware used by xiaomi isn't a poor one...). Those issues can also be more evident if you use a touchpen/stylus. So I was wondering, do you know if some workarounds or fixes can be used?
