Faster scrolling

being able to use my phone as a portable storage device via explorer and plugging it into a computer. No need for iTunes to put stuff onto the phone.

Better use of on screen space. I find the iPhone takes up too much space when bringing up the keyboard. There's just so much wasted space.

One for Samsung phones, the stylus. Can't live without it and I've had the note phones since the 2nd one and it's been my number one reason for purchasing them.

Being able to set any gif as wallpaper.

Other than that, I miss the removable storage and batteries. Back when Android was unstable and buggy. At least on Samsung phones.
