Tablet: Samsung Galaxy Tab 4 10.1" (SM-T530); Samsung Galaxy Tab A (2016) - SM-T5850. Often I have an issue that is shown in the video very well. When I click on the edge or middle (it's hard for me to understand) of the buttons, the character abruptly begins to look up, down or sideways. It happens very often during PvP, that is very annoying, because this bug makes me disorientated in space. This error is also on my friend's tablet. It can also be seen in many players on the servers. The bug exists from very early versions of the game.
