I guess this has been said before but I want to reiterate it here.
The 3 button navigation is simpler, much faster than gestures and less prone to input errors than gessure navigation.
It’s easier to use the phone one handed when using 3 buttons especially considering the size of phones nowadays.
The only real downside to the 3 button bar is the space it takes away from the screen. I can’t deny you get better immersion due increased screen size and gestures being intuitive (for me at least.
With that said I understand that depending on the brand the feel of gestures and their quality can vary (like between a pixel phone and a xiaomi device), but in terms of efficiency (and maybe slightly improved battery life due to less animations) and simplicity the 3 button navigation is still miles ahead.
None of this makes any sense. How are invisible gestures more intuitive than a button? And aren’t gestures literally “hand gymnastics”? Gestures and any “hidden” input are decidedly user unfriendly precisely because they’re invisible. I don’t recall specifics but there have definitely been apps where a user gets stuck on a screen because the developer unexpectedly opted for a gesture instead of a visible widget.
Gestures are good for the screen real estate part but that’s kinda it, IMO. I stopped fighting the current and (mostly) adapted.
