Black screen on samsung device

Has anybody else had this problem where you enter a fight but the screen goes black yet you can still import motions and can hear the fighting. It's happened occasionally since I've swapped to the note 10 + from the iphone 6s+, though it's been happening more frequently and just happened where I entered the arena where you choose the position of your champs. Which is why I'm posting this since it seems to be getting worse. So I would like to here if Kabam knows about this issue and if their trying to fix it.
