Cyanogens Koushik Dutta has been teasing the prospect of mirroring your Android screen on Chromecast for a few weeks, and today you can finally try the feature — if you have the right smartphone, that is. An updated version of the Mirror for Android beta includes early support for mirroring to either a Chrome browser or Chromecast, but only if you have a Nexus 5. Googles phone is the sole device with the hardware video decoder needed for this mirroring technique, Dutta says.
