Previously the only real Keyboard you could buy was Swift 3 and that’s what I did since I didn’t like the Samsung Galaxy S4 standard Keyboard. But as of June 5th the Standard Google Keyboard which was only available previously on the Nexus devices is now available as download for devices with Android Ice Cream Sandwich 4.0 and above.
There are different levels of predictive text as well as the swype option, it’s a keyboard with options and a clean feel. If you don’t have a Nexus phone try it out, you will like, its a different and clean feel for Google Keyboard. What I like is that they recently made it into its own App just like GMail, Maps, & G+.
