Go in game launcher and check if anything mentioned in screenshot is there or not and still nothing like this can be seen after playing minecraft then go to ask help and write feedback to samsung customer care.
No matter but if game launcher is showing the the play time then the game launcher is running in background to make your gaming experience better and also most of the times it is better that gamebooster icon dont get pop uped which is littlebit trouble making while playing a game so you set up your game launcher by going in game launcher apks setting and dont worry your device is running properly👍
