With this new feature, Google Photos users will be able to build animations inside the app itself when a working Internet connection is not available. Well, if you are planning to test out this feature, just temporarily turn on the airplane mode on your Android device and open up Google Photos. Once doing so, open up the Assistant tab which is located on the bottom left corner of the main page on the app, and tap the "Create new animation" option at the top. Then, simply select between 2-50 photos and hit "Create". You could also select a day such as "yesterday" or "today", and hit the same "Create" option. Google Photos will then create your animation which comes in the form of a GIF, which is stored locally for the time being. However, to be able to use this new feature, you will need to have the latest version of the Google Photos app which hit the Google Play Store yesterday. If your apps do not update automatically, then head over to the Google Play Store to manually update your Google Photos app.
This isn't Google Photos first feature which works offline, as there is already an offline feature whereby photos and videos you take will end up inside the app's gallery and will be backed up later when an Internet connection is available. At the moment, Google Photos has over 500 million downloads on the Google Play Store itself and has more than 200 million monthly active users according to a report from the company in May.
