In previous versions of Google Drive, file editing was basic, but with the most recent updates, the app has significantly powered up on that front. The Documents editor offers alignment options, lists, bold, italic, and underline, as well as a rudimentary color tool and the capability to edit tables. Meanwhile, the Spreadsheets editor is now worlds better than it was before. With the newest update, you have all the basic editing tools at your disposal, plus you can now change text color, cell color, and cell alignment. And it's important to know that formatting is maintained when you cut and paste content among documents in Google Drive. The downside is that the Google Drive app still lacks the capability to edit Presentations and Drawings. You can view them through the app, however. Lastly, the Drive app does let you create, reply to, and resolve comments via the Documents editor.
On top of all the old Google Docs functionality, Google Drive is really just a simple file storage platform. Like Dropbox, it automatically syncs with the cloud, so that everything is consistent across all of your devices. Also, it lets you share (add collaborators to) any kind of file, including music, images, and videos. Altogether, it is a fantastic option for storing, syncing, sharing, and collaborating.
From Google Drive's main dashboard, a quick tap on the menu lets you quickly sort and filter files so you can find exactly what you're looking for, even if your Drive is filled to the brim with files. You can filter by file type or document type, and sort by modify date. What's nice is, you can also move files around within your drive, in case you want to do some housekeeping.
Google Drive's sharing features are also impressive. The app lets you send a file straight away or send a link to download a file, all using Android's share menu. Previously, competitor Dropbox had the upper hand in this department, but Google's service has certainly caught up.
One thing I think the Google Drive app needs is a password-protect feature. As it is now, anyone with your device can easily fire up the app and tap into your private files. Dropbox currently offers this, and it would be nice to see Google come loaded with the extra security as well.
Regardless of its (few) shortcomings, I still highly recommend downloading the Google Drive app for Android. It nicely integrates (almost) all of the Docs functionality, plus it gives you the extra power to access and share other types of files.
