Maybe Siren should contact those movie apps devs and get tips on how they do it as their apps lives outside of Googleplay and would check for updates and download on their own.

How do i rename the character on Android?
The inbuilt "keyboard" doesn't have a backspace to delete"Player", and the game don't pop up Android's virtual keyboard.
Also there is no back button once you go into the options menu.
