I don’t understand many mobile OSes UX/UI. Take iOS for example, why is the web browser address bar at the top like a desktop OS browser, it should be placed at the bottom closer to your thumb/finger(s). The zoom in/out and compass direction on Apple Maps, why is this not placed at the bottom of the screen. Why does it feel that these mobile OS makers are forcing me to exercise my thumb/finger(s) and then produce “solution” such as reachability. Even to view Control Centre on iPhone X at the top right makes a users to needlessly reach to the top of the screen, while a swipe down to active reachability. How about a swipe down at the bottom of the screen brings up Control Centre. If Ives is designing this UX/UI then he has lost the concept of form and function for design.
I don’t use a phone to exercise my thumb/finger(s), fix this stupidity mobile OS developers. I see Google in Android Pie has relocated the search bar to the bottom, at least their get it. Now make this universal. Basically using desktop OS methods of navigation on a mobile OS. Might as well add mouse support since you are still sticking to the desktop OS design language.
