A jingle whose volume increases. It is also the same as you hear when you “call” your iPhone from the Apple Watch control center. As a reminder, the current sound is as follows:
The music player on the locked screen now displays an animated wave that reacts to the beat of the song. It’s just to look pretty, nothing happens when you tap on it.
This beta also brings a new option Copy and Delete for screenshots, as well as battery percentage display on (some) iPhones with Face ID.
