Another glaringly obvious thing with Android that frustrated me to no end with iOS: Why the fuck do you need to swipe twice to remove a notification. So many swipes wasted that I could've used for Tinder instead.
I have a boatload of stuff that annoys me about iOS, to the point where at one point thought about opening a Twitter account to send a daily tweet about something that sucks on iOS.
Emojis look good though.
They've actually made it worse in a way by removing the magnifying glass, but at least the new copy/paste/cut swipe gestures are handy, if a little odd on smaller screens.
The biggest loss for me on newer devices is 3D touch, since that's the best way to select text quickly and easily.
On many websites it will zoom around unpredictably.
Very awkward to select specific text in Notes etc. sometimes, especially around links and other clickable items.
I’ve found that if you try to move the cursor with the keyboard it’ll show up.
And for the love of god why does your spellcheck keep trying to replace the word "talk" with "ya'll?" I've had to manually set text replacement for way too many word pairs like that, and if you do typo the word you're going for in a way that's not in the text replacement, it defaults to the weird choice anyway.
This is something Android messed up since Android 9 (IIRC). You used to have a small arrow below the Wifi and Bluetooth (and whatnot) icons where you could select what to connect to. Removing those since 9 was partially what drove me to angrily expore iOS.
Can't say about the spellcheck because I used Swiftkey on iOS but the Android version is miles ahead of it. In hindsight I should've probably just reverted to the iOS built-in one.
My ideal is that I can flip up and change the source in the time it takes for a song to change, which I used to be able to do seamlessly in Android. Though according to the sibling comment, Android got worse for that use since I switched too.
Just wish both had some kind of UI indicator that there's a long-press action available... it's not like people are reading mobile phone manuals nowadays, even if they existed.

Personally I think the down arrow is way too small for me to press so I always just long press the icon anyway.
