Best Android Tablet Keyboard

Android tablets come in many shapes and sizes but there is one Android keyboard that I find superior above all the rest for android tablets. This keyboard is called thumb keyboard and it is amazing! What it does is separate the keyboard onto both sides of the screen making it exceptionally easier to type on while your device is in portrait mode. It also still keeps the spacebar and certain common letters on both sides which other keyboards lack. Overall this is a great replacement for the stock android keyboard that works exceptionally well on 10 inch devices.
