I'm not really sure if this is a bug or a glitch in my screen but I've been experiencing this for a while and its so annoying. Whenever I sprint, then attack a mob, my screen flicks to the left. When I hold my finger to the screen, it seems like my 'touch' is at the buttons. It just feels like that whenever I release my finger from the screen to hit a mob one more time, the 'touch' goes to the buttons.
