But that's not actually it. People who go from iPhone to Android find Android difficult to use. People who go from Android to iPhone find iOS difficult to use.
I'm now convinced the greatest UI innovation this century is the Back button. If IBM PC keyboards had a big dedicated "back" key the world would have a been a much better place.
So weird.
I used my coworker's iPhone yesterday, opening a link from a text message, and couldn't figure out how to go back to the message. Swiping in from the left side went back... within the browser, which had no back history. I had to go to the home screen and open text messages again.
On Android, you just hit the back button and it goes back to the previous app in the stack if you launched one app from another.
If you want to go back to the previous app you can swipe from the left on the home indicator, or on older iPhones swipe from the left with force.
The other problem is that no application trains the user doing this with for example an animated hint.
Knowing and using that makes the back button for users without disabilities superfluous.
While the author has mentioned a lot of things that I never knew existed or even care about, I don’t understand why Apple should have to make these things obvious for people who would never use them.
