The Live Photo feature from Apple records what happens 1,5 seconds before and after you take a photo. This recording is saved as a video file and is connected to your photo.

All your Live Photos on iOS will have a small icon in their top right corner. 

Our apps will play a short version of the Live Photo automatically (much like the Photos app on your phone). You can tap and hold the screen to see the full length video.

In the Android application, all your Live Photos will have a small play/pause icon in the top toolbar. 

Live Photos will play automatically by default. You can also tap on the live photo badge, or tap and hold your finger on the photo to play it. Autoplay can be toggled on or off in the mobile app settings.

All your Live Photos will have a small icon in their top left corner when you open them on the website. 

The Live Photo will autoplay or you can hold the mouse over the icon to view it.

When you open a Live Photo in the Apple TV app, the "video part" of the photo will be automatically played once.
