Although it only looks like a small jump on paper, the update from Android 4.1 to Android 4.2 brings a number of great and useful features to the mix: a Swype-able keyboard, a completely redesigned camera interface, and support for multiple users. But, for me, the highlight of Android 4.2 is the new Miracast wireless mirroring service.
On Android 4.2, you can now transfer content wirelessly from your smartphone to your TV. Not just movies and pictures; you could actually display the game you're playing on the big screen. just imagine: everything from your screenshots to your browser to Wind Up Knight could be beamed to a flat screen TV. All you need is a wireless adapter, which you can easily purchase from sites like this one. Just plug the adapter into your TV and you're good to go.
Miracast is the standard service used by many manufacturers – including Nvidia, Texas Instruments and Qualcomm. All TVs from LG in 2013 will feature native Miracast support. But it's not a brand new technology. Samsung features something similar in their current crop of Android phones, while Apple has AirPlay. But with support in Android 4.2, Miracast will get the push it needs to go bigger.
What do you think? Do you find this feature as awesome as I do?
