My complaints are that the OS seems slow. Maybe it's the animations, but it feels slow.

Or when podcasts are buffering, instead of giving an indication, the play button stays on pause. Confused me until someone on the internet told me.

The UI is unintuitive, but for work purposes it was fine.

Found the near daily updates I had to "sign in" AND enter passcode for annoying. Especially when I was in work crisis mode.

Not sure why Android doesn't have these problems, but I don't understand why anyone would get an iPhone, they feel years outdated.
