Hey, just tested your apk file, on my device is working flawlessly.
It might be your device, i do not have a expensive device to test on, im using a Galaxy A3 from 2014-2015 and i see no problems, regarding the ball movement, all is smooth, no jiggers no snapping movements, only when it hits the walls does a weird recoil(meaning when the ball hits a wall, it kinda jumps a bit for like 1 frame worth of time but is stabilizing after a while and doesn't do it, it might be a pre-loading issue not sure) but i think that is the way you coded it.
You might want to debug your apk build for errors or stuff like that.
If you wonder what the device is i posted a picture bellow:
