New split view Google Keyboard available for Nexus 5, Nexus 6 and Nexus 9
If you are using one of the Nexus devices we previously mentioned, you can turn on the split view by going to Settings > Language and Input > Google Keyboard Settings > Advanced > Appearance and layouts > Split Keyboard. While only the specified Nexus devices are able to get the split QWERTY for the moment, hopefully once Android M is released, all phones updated to the new build are given this option.
Check out a couple of images showing the new split Google Keyboard by clicking on the sideshow below.
Thanks for the tip!
