I suppose there is definitely a benefit to having a universal back button. I just can't say I've used it much, even on my samsung tablet. There's always some sort of button to get "back" to where I was. Just tried on messenger, youtube and instagram. All the "back" buttons were in the top left. Guess I never really paid much attention to that.
