what other features did they remove in OneUI 7?

I'm about to update, but before doing so I'd like to know what else they've removed so I'd adapt to using my phone more easily then just finding out it was removed hours later, especially after I've heard from this sub that some of the things I use often is straight up gone.

I've looked everywhere but every single place I turn to only mentions the new features, not the ones they've removed.

Thanks in advance!
