Innermost key of the screen for the touchpad movement (walk right movement key if movement keys are on the left, and walk left movement key if movement keys are on the right,) malfunctions by acting as if it were invisible. Taping and holding on the key with have the system act as it should and move the direction of the corresponding movement (right movement key if movement keys are on the left,) but only for a brief second before thinking the action is to break a block on that side. As a result, movement and building is bugged into switching the action for moving the direction into the screen (right if keys are on left) for breaking blocks and holding the screen in place with that movement touch instead of recognizing the other touch on the opposite side of the screen.
