You don't always have the time to save your files when disaster strikes, that is what makes the auto-save feature extremely useful in Word, Excel and PowerPoint for the desktop. You can even configure auto-save to save every x minutes. Today, Microsoft has brought this feature to its productivity suite for Android. Installing the update will automatically activate the auto-save feature, but this can be turned off by taping Save in the apps menu. Unfortunately the mobile version of auto-save does not include the save interval like its desktop version but it's better than nothing.
Another useful feature that Microsoft added is version history, another feature ported from the desktop world. Version history actually saves a snapshot of your document and future edits you make to the document do not overwrite the previously saved version. This is handy if you want to go back to a previous version and not having to shuffle through multiple version of the same documents on your device. Finally, Microsoft added Collaborative authoring to Word for Android, a feature that lets users work together on the same document at the same time.
Some of the features Microsoft added are specific to their respective apps. For example, Excel gets the Fill Handle that lets users drag the handle to automatically fill up cells with data.
PowerPoint for its part lets users take pictures right within the app. PowerPoint Mobile for Android also supply high quality pictures based on pictures that users supply for their slides.
