iOS 17: Top new features and upgrades

iOS 17 FaceTime users can now video voicemail, for the times when someone can't pick up the call. Live voicemail also transcribes messages in real time, so you can see who's calling without picking up.
The Check-in feature that's now part of iOS 17 Messages lets family and friends automatically know when you've made it home safely. This can also notify people if you've hit a hurdle, with information like battery level and the route you've taken.
iOS 17 AirDrop is getting an upgrade called NameDrop, which lets you share information, files and kickstart SharePlay experiences by bumping two iPhones together. 
The Journal app is not part of the iOS 17 public beta, as that new app will be part of an iOS update later in the year. (See what other iOS 17 features won't appear in the initial release.) When the Journal app arrives, it will personalize suggestions and writing prompts to help you document what you've done and where you've been.
StandBy mode essentially turns your iPhone into a smart display, offering information at a glance with easy-to-digest pages and voice controls.
The "Hey Siri" command is now just be "Siri." Other iOS 17 Siri changes allow Apple's voice assistant to recognize back-to-back commands without making you say the wake word multiple times.
Apple Maps now supports Offline downloads, so you can get around without a live internet connection
