Preview Lightning Web Components on Mobile

When you’re developing Lightning web components, it’s important to inspect your components’ presentation not only on the desktop, but also on mobile devices. To preview your components on virtual mobile devices and see changes as you code, use Local Dev. You can also download and run virtual device builds of the Salesforce mobile app to preview how your components coexist with other components in Salesforce.

To provide feedback and suggestions for Mobile Extensions and Salesforce mobile app downloadable builds, use the Mobile Tools Trailblazer Community.
