Custom launchers — apps that replace the home screens, app drawers and (sometimes) widgets on our Android phones and tablets — have long been popular amongst the Android faithful. Chances are you can find a launcher with exactly the features you want to make your Android look and act just the way you want it to look and act. Google shares the code for a good, albeit basic, launcher with everyone. The big names in the business, companies like Samsung or LG or HTC, can use what they want and add to it, or replace any part to make something they think is better. And so can the third-party developers out there, as well as "hobbyist" developers. And there are plenty of smart folks who are doing it.
Here you'll find links to popular third-party launchers you can download direct from Google Play. We highly recommend you dive in and give things a try!
