What basic things are missing? As someone who's using a 14PM I often find myself saying the opposite. iOS lacks so many things that make android phones great

That's funny, i went from a 6 pro to a 14 Pro max and I agree with you in a lot of points. To me, iphones are boring, but boring isn't bad. Yes overall I'd say my experience on the iPhone is more polished but that's not to say it wasn't polished on the 6 pro. I do miss the camera on the pixel as it was much better imo. Apps do run better on iOS though WhatsApp, weirdly enough, is the one I solidly prefer on Android.

I do wholeheartedly disagree about notifications though, they're done so much better on Android it's kind of ridiculous. Also, the typing experience is much better on Android too. But to each their own. I do love the hardware of the iPhone but it's software makes me want more.

Is it like Vanced?

I wouldn't say android doesn't work out of the box. There's just a lot more you can do after the fact as well
