> Finding apps and launching them quickly seems like an art to learn.
Swipe up from home screen, the launcher + search bar appears.
It is somewhat annoying that none of the primary buttons now brings up the launcher, but that change happened long ago. :/ IIRC pressing the home button while on the home screen would make the launcher appear. Since it is Android there is probably a utility to add that back.
Of course users can also arrange apps on their home screen however they want and ignore the launcher altogether.
> Funnily enough, among all the Android users I’ve seen, everyone has a habit of force killing their apps every time they close it!
I haven't witnessed this, but anecdotes are useless! I've had to show iOS users how to force kill misbehaving apps. Back in the days of 1 button knowing the right sequence of taps / holds to activate any of the button's many features was, well, the exact opposite of intuitive. Not that the modern practice of various arbitrary swipes around the screen to do stuff is much better.
On stock Android, one button is switch task, one button is go home, one button is go back. Three of the most common things users want to do, all right there.
A quick access menu + notifications can be pulled down from the top. Pull down once to get notifications and common shortcuts (Wi-Fi, flashlight, rotate, Do Not disturb, shortcut to settings), pull down again to get less commonly used options (Airplane Mode, BT Toggle, manual brightness adjustment)
Media playback stuff is done in the same UI as notifications, media playback apps pin a card to the top of the notifications list. No separate UI to learn, everything is in one place.
Don't get me wrong, Android used to be terrible. It was slow, buggy, and background apps had free rein to thrash the system to the point of it being unusable. But now days it is pretty good.
Also I can set my own animated wallpapers, so that is pretty nifty.
(But seriously, Windows Phone 7, most discoverable UI ever!)
