Some games are just finicky on devices due to how the screens are. My phone isnt to stable despite my finger not moving there is often a wiggle. This is what messes up the game. (Example minecraft is unplayable on my grand prime due to the touched point wriggling. Even tho i press at one steady point, the game will shift slightly as the screen doesn't understand and shifts slightly around the point) Ik it doesn't make much sense.
