Screen mirroring allows you to cast your device to another. For example, if you have a Windows device, you can use the Your Phone app to cast your phone screen to your computer. A similar feature may soon be available for Chrome OS.
Back in September, a flag spotted on Chromium Gerrit revealed that a feature called Phone Hub was in development. This feature will improve communication between Chrome OS and Android devices by allowing users to receive notifications from their Android device on a Chrome OS device. But that's not all.
This feature will also allow users to sync Chrome tabs between the two devices, find a missing phone, enable Do Not Disturb mode, and respond to notifications on their Chromebooks.
9to5Google discovered that the Phone Hub can get a feature that practically duplicates your phone's screen on a Chromebook. However, this feature may be exclusive to Pixel phones. The new flag is specified as # echo-swawhere "eche" is Spanish for "to throw" or "toss" and SWA is a system web application.
The description of the flag says that the web app is associated with a video stream broadcast via WebRTC. The XDA developers have stated that the reason it is exclusive to the Google Pixel line of smartphones is because the Javascript for the Eche app resides in the Google source folder, which is specific to Pixel phones. However, we hope it will be available for other smartphones, so instead of being exclusive to the Pixel, it will be Pixel-focused, just like Instant Tethering.
There is no information on when the feature will launch, but it should arrive this year. The core Phone Hub feature is already available to very few users, but it should also see more adoption in the coming weeks.
