Google Drive with 5 GB of internal storage is one of the best cloud storage offerings if you are using an Android device. There are very few alternatives to native Google Drive app on Android. One of the new app is GDrive Sync, which is already featured on the XDA.
The app has now officially made to Google Play, and is available for download. GDriveSync allows you to select folders and from where you can make the phone automatically upload items to Google Drive. You can enable the syncing as manual or automatic, and choose the connection medium (3g or WI-Fi) for usage.
The app supports the selection of multiple folders at once. In my case, I selected the DCIM folder which is the camera folder on the SD Card to auto-sync. The app is promising, but the performance was laggy at few places. We believe that the developer will address those issues with coming updates. The app has been made available for free.
