  • Android devices -The WebRTC app is not yet optimized for smaller screen devices such as Android phones and tablet.

    • OnePlus 5 (A5000) running Chrome 67 on Android 8.0.0

* Important disclaimer: Please note that due to the large range of Android devices, with many combinations of software and hardware specifications, it is not possible for Cisco to test all devices. We endeavour to investigate interoperability issues but there is no guarantee that any particular device would be fully supported. The absence of a particular device in the list above does not imply a lack of interoperability.

Older versions of the app

Previous versions of the WebRTC app is known to work from Chrome version 28 onwards.

Note: Chrome version 33 onwards is required for screen sharing. Screen sharing is not enabled by default in Chrome v33 to v36, so you will need to enable it if you haven't already (The app shows a message with instructions to enable sharing if not enabled).

From Chrome v37 onwards, native screen sharing is no longer possible. Hence Cisco provides a Chrome extension to enable that functionality. Refer to this FAQ for information on how to enable this.
