How to use Google Handwriting Input as an alternative to typing on a keyboard. If you are still typing messages and emails on a tiny smartphone keyboard, you owe it to yourself to try the current version of Google Handwriting Input. Screens have come a long way, and Google has created a really easy way to input text on its current smartphones. You can use a stylus from the office supply store, or the stylus that comes with the Note series of phones, or your finger. The results are surprisingly accurate, and you can pick the handwriting option anytime you are inputting text into any app. Really easy.
