The Google app Photos just added a new one mode for users of service at Android.
Version 5.22 of the application offers the ability to automatically convert the photos you have selected into live wallpapers, i.e. wallpapers for the mobile that change by themselves (using AI).
If you have Google Photos installed and your phone supports live wallpapers, you will see a new option called Memories.
If you use the new setting, live wallpapers will capture machine-selected photos from your Google Photos repository.
You may find this feature useful, but it can also be a reminder that Google will soon start charging for more than 15 GB of photo storage.
