SwiftKey is an amazing app on the Play Store, and they decided to integrate their prediction technology into the Samsung Galaxy S 4. And while the Play Store version of the app is not installed on the S 4, Samsung modified it for their liking and used it as the stock keyboard. Something similar was done with both the Galaxy S III and Note II, but this time, SwiftKey actually announced it. And with SwiftKey being the best keyboard (by far) for many, this could make a lot of consumers happy. Those who never switch out the stock keyboard will be getting a good user experience. Will you give it a try?
