Hard to believe the difference. Android is really bad at many things, and I had a good brand (One Plus 6).
Taking a picture on Android is an awful experience. The Camera app takes about 3 seconds to open, and freezes for a second when taking a picture.
The Camera app on iPhone opens instantly and takes photos instantly.
The quality of the pictures taken on the iPhone are also much much better.
I don't like the closed model of the iPhone, but the quality is currently unbeatable.
