What new features are a part of iOS 17?

iPhone users will be able to put their phones into standby mode while the phone is charging on its side. In this mode, the phone can function as a clock, shuffle through photos or operate widgets.

The new operating system will also introduce live voicemail screening. With this feature, a user can read a transcript of a voicemail in real-time and decide whether to pick up the call.

FaceTime users will be able to project their calls to an AppleTV device. The iPhone or iPad will serve as the outgoing camera, but incoming video will be seen on the larger screen.

The new NameDrop feature, an outgrowth of the AirDrop feature, will allow iPhone users to exchange contact information by holding their phones close to each other.

What will iOS 17 improve in iPhones?

FaceTime users will now be able to leave video messages if the person they are calling does not pick up. The messages will function similarly to a voicemail and callers will have available to them all the assorted video effects that a completed FaceTime call would. Users will also be able to program iOS 17 to automatically silence FaceTime calls from non-contacts.

For those who use iPhones as a phone, the phone app has added capabilities to create new visuals to alert a person for a call from a contact.

The Autocorrect and predictive text features will also be improved in the update.
