CloudVault Photo Uploader does what Google has still not delivered through their Google Drive mobile app.
CloudVault Photo Uploader works like Dropbox and automatically upload your photos and videos from your Android phone to your Google Drive account.
Google has a similar feature that works through Google+ mobile app but it resizes the images before uploading.
Dropbox’s official Android app of course already has a similar feature but not everyone uses their online storage locker.
If you have been looking for a way to backup your phone’s photos and videos on your Google Drive, this is the app you might want to check out.
