iOS 8 is a teeming mass of code, a carefully crafted cornucopia of new features. Some, Apple has marketed to the skies. Others are quiet touchups that you’ll just stumble upon.

You can read about some of the buried treasures in our story here . But right here, on one handy page, are 13 more. You might call them Dave’s Faves.

1. Send the most recent photo.

When you’re texting someone, and you want to send a photo, which photo are you most likely to want to send?

Why, the last one you took, of course. Or at least one of the last few. iOS 8 realizes that and saves you the hassle of burrowing through all your photos and albums to find it.

Where to find it: When you’re in Messages, tap the Camera icon. BOOM: The last few photos you’ve taken or imported are right there in front of you. Scroll to the left to see more of them, going back in time. Tap the one you want, and then tap Send 1 Photo. (Actually, you can tap more than one, if you want.)

2. Last known location.

Your battery dies. You can’t find your phone. Now what? You can’t use Find My iPhone if your phone is lying dead under a couch at a neighbor’s house, because that feature used to work only when your phone could respond.

Thanks to this update, you now have a prayer of finding your phone again. Before it dies, your phone will send Apple its location. You have 24 hours to log in to iCloud.com and use the Find My iPhone feature to see where it was at the time of death. (After that, Apple deletes the location information.)

Where to find it: Open Settings → iCloud → Find My iPhone. Turn on both Find My iPhone and Send Last Location.

3. Hands-free Siri.

Apple is keeping up with the Joneses — or, rather, the Motos. Now you can command Siri without having to hold down the home button. Just say “Hey, Siri” to get her attention — and then speak your command.

This trick is especially good when you’re driving. If you must use your phone, doing so without looking at it or touching it is the best way.

The feature works only when your phone is plugged in to power, though.
