Huh?
iOS didn't let you use custom icons for apps until 2020.... How does android suck when it has let you change almost every aspect of your phone for decades?
I think what people usually mean is that they like that iphones have iMessages and icloud where all the apps constantly sync to iCloud without the user having to think. That and airdrop launching in 2013.
My GrapheneOS pixel lets me install whatever I want from any source I want so I install open source everything from github and zapstore, let's me make it look like anything I want including but not limited to looking almost identical to an iphone, it doesn't secretly spy on me and all my keystrokes or force packets of data around my vpns back to apple servers, has every nostr client, lets me connect to all my own servers with self hosted apps privately.... Goes on and on. I'm very confused as to how android "sucks" relative to ios.
Oh and btw on android you can just run bluebubbles or openbubbles and have iMessages without having your entire phone be one big spy device for apple. ๐ค
