Dropbox for Android receives update to level the playing field with iOS version
The update brings a redesigned search feature that tracks previous searches and suggests searches using "typeahead" recommendations. And as you type the name of files or folders in any field, matching names will appear. You can also preview any Word document, PowerPoint presentation, or PDF in your Dropbox directly from your Android device, with the ability to view, scroll, and zoom.
And if you are sharing a Dropbox with your business associates, you can arrange to give them view only access to certain documents and files. This way, you won't have to worry about Reggie in the corner office changing the Anderson contract, without your permission. The update also includes the usual bug fixes and improvements, and can be found at the Google Play Store.
