To render a SharePoint Online site for an optimized mobile browser view, the Mobile Browser View feature for a site needs to be activated by the site admin. By default, this feature is already turned on when sites are created using certain site templates like Collaboration templates (Team Site, Blank site, Document Workspaces and so on). Meeting templates and Enterprise templates (Document Centre, Records Centre and so on).

On smartphones (supporting HTML5), end users can themselves switch between the mobile view and the PC view using the settings menu on the Mobile UI.

For this demo I have used a Samsung Smart Phone with Android O.S version 4.4.2 and Google Chrome browser.

1. Opening and Browsing The site

2. Working with Document Libraries
