Use the ‘For You’ Tab
The Photos app has a For You tab, which captures all the memories your iPhone thinks are important. You’ll find different events or themes, all filled with the photos you’ve taken of yourself or your friends and family.
The Photos app will automatically create these moments for you, so all you need to do is tap For You at the bottom of your screen, and you’ll see everything Photos thinks is worth remembering or sharing.
Granted, you aren’t the one organizing your pictures, but this is a great way to quickly find moments you didn’t even remember.
