when you try to open the app it just sits on the mojang screen and does nothing so you have to close the app and try again and it can take you about 20 tries before you can go to the main menu and then when you open a world/ start creating one it doesn't show the green loading bar and takes about twice as long to go into the game and once you are in the game if you put the device to sleep the game freezes and you have to go back to the start (by back to the start i mean that you have to close the app and try again but your world will still be saved)
