I'm with you. I got an iPhone 15 a couple of years ago after only ever using Android. I was expecting great things and it's just.. confused!
I never have any confidence it will notify me of things. Often I just miss stuff. I actually have no idea how all the different "Focus" modes work. Notifications pile up and then seem to disappear without any action, and then reappear a week later.
The keyboard is really awful. I recently pulled an ancient Galaxy phone out of a drawer to test something and was reminded of just how much better the Android keyboard is. It just always guesses the wrong things!
And the settings are equally jumbled. Sometimes they're in the Settings app, sometimes they're in the app I'm using. It's just confusing.
It was honestly eye opening because I'd spent so many years assuming iPhones were better. I moved across because my Android phones kept having hardware issues. I think I'll probably go back to Android after this experiment.
