Earlier this year, big changes were announced to Google+, as the search giant broke the platform down into smaller components, including Photos, Streams and Hangouts. Following up on that announcement, the company launched a new Google Photos app in May, and it's now ready to retire its predecessor.
The older Google+ Photos app will begin shutting down on August 1 - first on Android, before web access and the iOS app are killed off later. Users of the old app on Android should soon see a prompt encouraging them to download the new Google Photos app instead. As Google explains:
Don’t worry, all your photos and videos will still be saved and available after you switch to the new, stand-alone Google Photos app. With the new app you’ll still be able to backup, edit, and share your photos and videos, with unlimited storage, automatic organization, and more.
If you don't update to the new app, the company says that "Google+ Photos on Android will soon stop working, but your photos and videos will still remain safely stored and available via http://photos.google.com or for export using Google Takeout."
