Touch movement controls glitch out and leave my character turned 180 and looking directly downward at the ground

Using onscreen movement arrows to control my character in 1st person view, my character frequently ends up facing directly down and turned around 180 degrees from where I was facing. It happens multiple times in a minute if I'm fighting or if I lift my finger off the screen and place it back down on an arrow button.

It seems like sometimes the buttons don't register being touched, almost like my finger press goes through the controls to the environment beneath the movement arrows.
