This app is for Android users who want to backup their photos and videos in the cloud, but not inadvertently share them with the world like Google Photos can if you're not careful. Gallery Drive Sync will manually or automatically upload the images and videos in your photo gallery to Google Drive. If you choose to retain all of the backed up images on your phone you can optionally resize them for optimal viewing on a phone screen. The photos look the same when displayed on your phone screen, but can use as little as 15% of the space they occupied before, saving you gigabytes of internal storage. Meanwhile the backups in Google Drive are retained at full resolution. After your photos and videos have been stored on Google Drive they are easily shared selectively with friends and family. Note: it is OK to move or change the names of uploaded sub folders and images in your Google Drive. The app will still remember which files have been uploaded, however if you delete a generated sub folder it will be recreated on the next upload. If you have a limited data plan it is recommended that you only use the app over WiFi because to upload an 8 Megapixel photo will generally require a 2. 5 Megabyte data transfer. This app is dependent on Google Drive's availability to function. If you are experiencing persistent errors please check the status of Google Drive here: http://www.google.com/appsstatus.
