Install for This New Always On Display Feature
Samsung's updated the Galaxy Note 8's Always On Display with a new feature that reportedly requires Android 8.0 Oreo.
The Samsung Galaxy Note 8 can now take advantage of a feature that was originally exclusive to the Galaxy S9 and Galaxy S9+. That feature? GIF support for AOD.
On Android Nougat, GIFs on the Always on Display would appear static. With this update, you can now see GIFs in action when the phone is idle.
GIF animations run just once, likely to help conserve your phone's battery, but you can always double tap them to watch again.
In order to get the update, you'll need to open up the Galaxy Apps store and tap the three-dot button on the top right of the screen.
From there you need to select My Apps then select Update. Locate Always On Display on the list and select update again.
Once you've got it installed, head to your Settings > Lock screen and security » Always On Display. You'll then need to select either the Clock or Home button and clock under Content to Show.
Go back to Lock screen and security menu and choose Clock and FaceWidgets. Tap on Clock Style. From there, you'll need to select one of the preloaded GIF animations or you can opt to select one of your own.
