Which iOS 17 features are "backwards compatible" with older iOS versions?

[ethanomnom]

A quick search didn't yield any results so I don't think anyone has discussed this yet, I wanted to come up with a list of features that work with older iOS versions.

Some features that I know do work with older iOS versions:

• Live Voicemail (presumably should work on any call since it uses on-device transcription)
• The new stickers
• FaceTime reactions
• SharePlay Music in CarPlay (I believe I saw this working from other users postinga

Features that don't work with older iOS versions:

• FaceTime Voicemail
• Voice Memo transcriptions

Any others folks have noticed? Or any corrections to my list?

in my experience, the new stickers have not worked when I try sending stickers to my wife on iOS 16, likewise, I have yet to be able to use the new FaceTime reactions with her either.

Is that for both the new stickers and for emojis, or just the stickers?

I have not tried emoji, just turning my own photos into stickers.

gotcha. I am seeing now that in beta 2, the stickers show up on non-iOS 17 devices!

I’ve only been able to send them in a message. When I try to use them as a sticker it disappears
