> my lock screen has a camera icon always visible. When you tap it, you get an isolated camera mode that only shows you photos taken in that session. That's the standard screen now, so I think Apple is doing okay on the discoverability front (for that specific use-case -- possibly the only case where something is discoverable in iOS). Huge discoverability hiccup with that camera button on the lock screen: you have to tap and hold the camera button to get into the camera (not long, about 1 second). The first time I picked up my partner's iPhone to take a picture for her, I just about pulled my hair out trying to get that button to do anything. I tapped it about a thousand times before she got frustrated and showed me how to operate it.
