Tablet App ignores Touchcommands

Hi,
at my Samsung Galaxy Tab A 2016 i have the Blood Bowl App.
Roundabout every 2nd game the App goes ahead with the game (time is running and the KI are go ahead) but ignores all touchcommands. I can use the Tablet for other Apps normally but if i switch back to Blood Bowl theres no way to play because the App loses the connection to the touchpad completely i think.
