As soon as you share your screen, it's automatically visible for the other call participants. They can annotate your screen share from their device or from the Webex app. When another participant shares their screen, that content opens on your device and you also can annotate it.


During a call, share your laptop or mobile phone screen on the Webex device. Read this article about wireless sharing and this article about sharing with an HDMI cable.

If your device is on personal mode, see this article about sharing your screen wirelessly during a call.


Tap on the bottom left corner of the device screen to start annotating. If the button isn't visible, tap the screen once. Opening the drawing function can take a couple of seconds.

You'll get the standard whiteboard drawing tools at the bottom of your screen and can use them to make your annotations.


Swipe up on the device screen to open the task switcher if you want to leave the shared content whiteboard at any time. To go back to annotating, swipe up and tap the whiteboard in the task switcher or tap and select the whiteboard there.

Swipe up on the whiteboard in the task switcher to close it. It will still be available by tapping the Files button on the home screen.

Click Stop sharing on your laptop or phone to stop sharing your screen on the device.


When you're finished annotating and the call is over, tap Save on the device screen. On shared devices you can choose to save your annotations to an existing Webex space or to create a new one. On personal mode devices you'll find your annotations in the Whiteboard tab of the Webex app space as a .pdf. Everyone in that space can view the image and continue working on it.
