Disable immersive mode on Android (or provide a back button close to the bottom of the screen)
With the most recent update turning on immersive mode on Android, I've come to notice how much I actually made use of the soft buttons at the bottom of my tablet when playing the game.
I know I can perform a swipe up from the bottom of the screen to display the buttons again, but that is slower and sometimes inadvertently activates one of the game's buttons on the bottom row. I also know that there is usually an in-game back button in the top left corner, but that is the least convenient place to put such a button ergonomically: my right hand will usually be at the bottom right of the screen, so this is about as far away as you can put the button.
If you don't want to turn off immersive mode again by default, please consider providing an option to turn it off.
