Google recently updated its Google+ iOS app to bring users full resolution photo and video backups. Background uploading got a bonus when iOS 7 was released, as Apple loosened some of the restrictions locking down its mobile operating system. As a result, the new full-resolution background uploads in G+ will only work for iOS 7 users.
Those iPhone and iPad owners running G+ on iOS 6 can still upload their photos and videos, but you’ll need to have the app running in order to take advantage of it.
In addition to the photo/video uploads, G+ on iOS will now display your friends along a map, finally replacing functionality that Google discarded when it decided to retire its Latitude geolocation app.
