Ever since its appearance in Android Pie, I always consider 2 button navigation is a bad attempt by Google trying to play catch-up with the fad generated by the iPhone X. However, due to a bug with A13 QPR2 it had to be temporarily removed and many were not happy about this. So, 2 button navigation users, may I ask why do you prefer this method? To me it makes you do more for the same action whilst doesn’t save any screen space.
Most likely, I did some more research into it last night and apparently a two finger swipe or a 45 degree swipe will activate the bar more reliably, both of which are a bit obnoxious. I’m sticking with it for now, we’ll see how it goes!
