Duo is a video chat application developed by Google, which is available on iOS, Android, and web browsers. Duo supports screen sharing, which means that you can share your phone’s screen during a video call with another person. In this way, you can show the other person photos, videos, or any other content that is on your phone’s screen.

To screen share with Duo on an iPhone, you need to follow these steps:
- Start a Duo call: Open the Duo app on your iPhone and start a call with the person you want to share your screen with.
- Tap the screen sharing icon: Once the call is connected, look for the screen sharing icon on the bottom toolbar. It looks like two overlapping rectangles.
- Choose what to share: After tapping the screen sharing icon, you will be prompted to select what you want to share. You can choose between sharing your entire screen or sharing a specific app.
- Begin sharing: Once you have selected what to share, tap “Start Sharing” to begin sharing your screen. The other person on the call will now be able to see your screen.
- Stop sharing: To stop sharing your screen, tap the screen sharing icon again and select “Stop Sharing.”
It is important to note that screen sharing on Duo is only available during a video call. Additionally, both you and the person you are calling need to have the latest version of the Duo app installed on your devices to use this feature.
In summary, you can easily screen share with Duo on an iPhone during a video call by tapping the screen sharing icon and selecting what you want to share. This feature is useful for showing photos, videos, or other content on your phone’s screen to the person you are calling. However, it is only available during a video call, and both users need to have the latest version of the Duo app installed.
