Here are the new features iOS 17.3 brings to your iPhone.

Stolen Device Protection

Apple’s iOS 17.3 introduces Stolen Device Protection to your iPhone, which aims to help protect you and your data. 

According to CNET’s David Lumb, Stolen Device Protection requires you to enter your biometric authentication, like Face ID and Touch ID, multiple times to access some of your sensitive settings and information, like your Apple ID password. This feature uses a new mechanism, called Security Delay, when you try to change these settings. 

If you attempt to change these settings when you’re away from a familiar location, like your home, Stolen Device Protection will require you to enter your biometric info, like your facial scan or fingerprint, twice; once initially and then again after an hour. However, since Stolen Device Protection only protects a handful of settings, you still have to take steps to protect other information, like your social media accounts. This is an optional security feature, but Apple recommends everyone turn it on.

In honor of Black History Month, iOS 17.3 brings a new wallpaper, called Unity Bloom, to all iPhones. According to Apple, the wallpaper shows an outline of flowers that will fill with color once the display is active. 

Apple Music collaborative playlists are here at last

With iOS 17.3, Apple brings collaborative playlists to Apple Music subscribers. The feature allows multiple people to edit and control shared playlists on the music streaming platform. You can also react with an emoji to a song in a collaborative playlist that someone else added. That way you can let someone know instantly if you like a song or not in the playlist.

Apple announced collaborative playlists in Apple Music at WWDC 2023 in June. The feature was included in some beta versions of iOS 17.2, but wasn’t included in the final release of that update.

Here are the full release notes for iOS 17.3:
