iOS Hidden Feature: Photos automatically sorted by person

When Apple released iOS 10, the latest system software for the iPhone/iPad, it made a big deal out of the major features, like a redesigned Music app and contextual predictions in autocorrect.

But Apple’s engineer elves worked for a year to overhaul iOS 10, and they’ve planted lots of hidden gems. Today, I’m happy to present another of the best iOS 10 features that Apple forgot to mention.

The iOS 10 Photos app can now auto-group the people in your photos, using facial recognition—for example, all pictures of your mom appear in a clump.

To see it at work, open Photos, tap Albums, and tap People. You can even drag your favorites into the top of the screen for quick access later.

This feature doesn’t work until iOS 10 has analyzed your photos, which can take at least a day (during which the phone has to be plugged into power).

Apple proudly points out that all of this analysis is done on your phone. (That’s in contrast to services like Google Photos, which offers similar features but requires that Google access your photo library.)
