My friend brought me a brand new Mi5s from China. I heard many good reviews on this phone so asked my friend to get me one. I was excited to unbox and it is a beautiful phone but soon found an issue with the screen. Running the touch screen test (from *#*#6484#*#*), put my finger on the screen and there is a coordinates showing my finger's current position on the screen. I then move my finger very slowly on x axis, there is no change of the coordinates. If I keep moving then the coordinates suddenly start to jump to where the new location represents e.g. from 500, 500 to 550, 500 (skips 501, 502, 503... 549 on x axis). I have run similar test on my other phones (galaxy s5, s7, note 4) all have no problem , the coordinates change immediately if I move my finger.
How did I found this? I found this when I was playing fps games. When I slowly moved my finger to aim, the cross just doesn't move and if I keep moving my finger, it suddenly jumps.
Here is a photo, dx and dy on top of the screen shows how much movement i have made on the screen. I have tried to move to left, so dx is -51. I can't make a horizontal enough move so there is some movement vertically hence dy -10 . The issue is there is no way to make a movement less than that, say 1 (or -1). It doesn't register the tiny movement until at some point the accumulated movement is around 50 .
Is this a faulty item or just design bug?
