Just a few weeks after it was first announced at Google I/O this year, the Android screen mirroring feature has started rolling out for Chromecast. The new feature, which makes Google Cast much more similar to Apple's AirPlay, is being made available through version 1.7 of the Chromecast app.
With this, owners of Android devices who also have access to a Chromecast dongle over a WiFi connection, will now be able to mirror their device's screen onto their TVs, enabling them to watch pictures and videos, as well as navigate apps, content, and anything else they want in a bigger screen.
To start mirroring, simply select “Cast Screen” from the navigation drawer in the Chromecast app and select your Chromecast device. Nexus device owners don't even have to go to the Chromecast app, as the option will show up in the quick settings menu.
It's worth mentioning that the feature isn't currently available to all Android devices; only select models are supported. These include Nexus 4, 5, 7(2013), and 10, as well as Samsung Galaxy S4, Galaxy S4 (Google Play Edition), Galaxy S5, Galaxy Note 3, Galaxy Note 10, HTC One M7, M7 (Google Play Edition), LG G3, G2, and G Pro 2. More devices will be added to the list soon.
Another point worth noting is that the feature is currently in beta, which means that there could be some issues when you use it.
