A leaked video shared on Twitter shows a Surface Duo opened just slightly. The time and notifications are clustered on the right side of the screen, and you can swipe to dismiss them. You'll also be able to preview and decline or accept calls.

This "peek" feature could be an alternative to adding another screen, as the Galaxy Fold and Galaxy Z Flip devices have done. Microsoft hasn't confirmed this feature, but last month it released a preview toolkit to help developers prepare Android apps for the Surface Duo, so it's not unreasonable to believe that it's in the works. Microsoft clearly wants developers to come up with innovative dual-screen experiences, and it could set an example with this peek-to-preview function.
