How to disable this.? For going back or to the home screen I don't wanna swipe twice for Every such action
You're talking about the side gesture or the home gesture?
Side and home, both require two swipes for one action when in a game.
I have that issue too. For streaming apps (Spotify, for example) and games (call of duty, Minecraft, etc), when I swipe from the side of the screen to go back or from the bottom of the screen to go to the recents or home screen, it says "swipe again to activate". Having to double swipe in most apps makes the gesture navigation feature go from useful to redundant pretty quickly.
Yes I find gesture navigation not convenient as well. I see most productive this setting
It only happens on apps/games I launch from the armoury crate and I am actually happy they made it that way to prevent accidental swipes in-game which is frequent for me specially for MOBA type games. Problem is it also happens even when you "alt tab" and do something outside. Personally I'd say the tradeoff is fine but can understand why you'd want it disabled.
Don't think you can disable it. As 3 buttons navigation need 1 swipe to bring it up and 1 click also. But the time required b/w 2 swipe is too short, I think it should be a bit longer so the phone will registered 2 swipe instead of single swipe twice.
