A little KitKat style on any device running ICS or above
The Google Keyboard is getting a nice update that brings it right up to speed with the latest KitKat features and styling, offering what was only available on the Nexus 5 for a few days. Now any device running Android 4.0 or above will see the newer black and grey look (no more holo blue here), along with a few new features. First up, the long-press menus have been revised and you now access emoji rather than just basic smilies if your phone supports it.
The update also adds "space-aware gesture typing," which is just a fancy way of saying you can swipe over the space bar rather than lifting your finger between words. You'll also see a better punctuation layout across phones and tablets of different sizes, making the best use of the real estate at hand.
You can grab an update to the latest Google Keyboard and get a taste of KitKat on your own device at the Play Store link above.
