Just like the Windows Insider program, which allows Windows enthusiasts to install and test recent pre-release versions of Windows 10 and Windows 10 Mobile, a similar program exists for Microsoft Office. A new build of Microsoft Office 2016 has been released for Office Insiders, this time for Android users.
The new build has version number 16.0.6528.1008 and is now available in the Google Play Store.
The change log mentions three new features for the Word app: auto-save, version history and collaborative authoring.
As of this writing, Office for Android includes three apps: Word, Excel and PowerPoint.
The following apps are available for download via the Play market:
However, you will not be able to install those apps unless you receive an invitation in the official Google+ Office Insider for Android community. You need to join it first using the same account you use for the Play Store on your Android device.
If you are running a Windows PC, you might be interested in installing Microsoft Office 2016 16.0.6366.2062, which was released for Office Insiders recently.
