Back button closes game from main screen without warning (android): Please add 'are you sure' pop up

Honestly, I can't be the only idiot that hits the back button from the home / main screen and the game closes. At least once a week. 
Can we get a simple pop up that asks if we're sure?

This would save accidental closings. Sometimes my error here results in me losing cached targets in PvP, or simply the game-reload time when I'm in a hurry clearing different nodes for example.

It's completely my fault, but you could easily save me from this mistake. Most games ask if you're sure before closing.

Android. Not sure about iOs
