Microsoft yesterday released a preview of the January 2018 feature update for Office Insiders on Android devices. This Build 16.0.9001.2005 comes with a couple of new features.
First, Word for Android now supports writing and editing math equations. Users can now write their math equations in linear format, for example like a2+b2=c2 and Word will convert it into professional display format a²+b²=c².
Second, users can now easily find out who has edited the PowerPoint presentation and what changes they’ve made. This can be done by checking out the slides that have a green highlight.
You can download the latest update from Google Play Store.
