In a recent update on February 19, 2014, OneDrive for Android added the automatic photo upload feature, called Camera Backup, that the iOS and Windows Phone versions of the apps have had for some time. Once you turn it on, every photo you snap and video you record will automatically be saved to OneDrive. You can choose to upload those files over Wi-Fi only to save data, if you wish.
What the app can't do, however, is move files around between folders in your OneDrive account. Even if you create a new folder in the app (which you can do), you can't add any files to it. So, if you need to do some housekeeping, it's probably a better idea to do so through a browser, as the app can only delete and create new folders. That missing feature makes the app much less useful than its Windows Phone cousin, and we hope that Microsoft adds it in a future update.
Probably the biggest omission from OneDrive is a built-in interface for viewing or editing Office files. Instead, if you want to look at or make changes to your files, you have to download them locally, then use a third-party app such as Google's QuickOffice or Polaris Office, which comes pre-installed on many Android devices. But if you do this, your changes will affect only the downloaded files, and not those saved in your OneDrive.
However, if you have an Office 365 subscription (which starts at $60 per year) and theon your phone, you can tell OneDrive to open Office files in the Office app and edit them there. Any changes you make will then be saved to the cloud via OneDrive.
In future iterations, we would love to see basic viewing and editing functions for documents built into OneDrive. That way you wouldn't need a third-party app to make edits, and changes would sync automatically to the cloud. Also, it would be nice to be able to protect the OneDrive app with a password or some other security feature.
While the OneDrive app does look nice, and just recently got the Camera Backup feature which brings a bit closer to the level of the other OneDrive apps, it still has a ways to go in terms of functionality. Before we can give it high marks, we'd love to see password protection, a way to move files around within your drive, and of course, a built-in way to edit Office documents.
