MORE FIXES, MORE BUGS IN 1.2.13

Specific - Samsung S7 ; I dont know if these occurs on other samsung android phones or not BUT this is first bug.
Everytime i quited minecraft and then went back to it again, minecraft wont load up and just... black screen. I need to turn the game off to make it sleep from the tabs and restart minecraft to make it work.
2nd bug. Sometimes when i get out from the world, the 'saving the game' screen flashes and it stays like that until i either restart the game or i turned to the tabs and went back to the game.
C'mon MOJANG, till when will all of the bugs in Bedrock be finished?
