If there were one useful feature that would be handy on Smartphone or tablet, it would be being able to search Google by writing with your finger. Well Google have listened and delivered Google: Handwrite; naturally, this is for Android powered devices and it is easy to get, but tapping “Settings” and enabling “Handwrite” easy!
In a posting by Rui Ueyama, Software Engineer, on the Official Google Blog, they talk about Google: Handwrite;
Unlike searching on a desktop or laptop computer, when you’re searching on a touch-screen mobile device it’s often inconvenient to type.

Now there’s a new way for you to interact with Google: Handwrite for web search on mobile phones and tablets.
