Emulator

If I hit the back button and lose progress one more time I'm going to throw my phone out the window and it's a very expensive phone and I'd rather not do that.

Please add a "Are you sure you to close emulation," popup or maybe even an option to disable the back button while you're in emulation. The One Plus 5 is so sensitive with the home/back buttons that I hit them a lot while trying to reach over and hit the touchscreen.
