Once activated the app will signal that screen sharing is activated, while also letting you stop broadcasting at any point with a single tap in the top left corner. The ability to screen share is arriving on Android and iOS soon, with the feature rolling out for Skype Insider users now. As it stands, the added features will enable users to share anything on their phone displays to whoever they're engaged in a video call with.
Since acquiring Skype, Microsoft has been slowly but surely developing the messaging tool, most recently increasing the number of chat participants to 50. This new build brings screen sharing support to these apps.
If you'd like to try the new screen sharing feature, you need to be part of Microsoft's Skype Insider beta program. The option can be accessed by tapping the three dots at the bottom of the screen, and then selecting Screen Share. Microsoft suggests this will be useful for sharing PowerPoint presentations, or collaborating with friends as you swipe your way through Tinder matches.
As mentioned, the update is rolling out to Insider build users, so it may be a while before all users see it.
One thing to note is that the feature may not be available in the iOS Skype preview program just yet, according to The Verge.
