I would miss the ability to multitask by split screening apps or doing floating app with my S23U. I would miss my spen which I use to take quick notes, and then can slot back into the phone which even the iPad Pros can't do. I would miss having a non Safari browser like Firefox and its addons. I would miss the easy access to foss apps like NewPipe, and apps not allowed on the Apple store like tachiyomi, emulators, and torrent clients. I would miss that syncthing type apps don't properly work for syncing across different platforms. I would miss the launcher, since I'm not a fan of Apple launcher and app library aesthetics. I would miss the Android folder system's easy access to everything in there compared to the iPhone. I would miss one hand operation+ method of navigating over Apple gestures.
I would like the long term updates of the iPhone though. Using the iPad though made me never want to get an iPhone.
Safari + sponsorblock to airplay YouTube videos to the TV without needing some third party app like smarttubenext on the TV or logging into YouTube premium.
No ads and skipping sponsors with just no extra steps and no need for any other apps is nice. Especially since I don't even have the YouTube app installed.
