That's the huge advantage of Android vs the iPhone. If you aren't happy with the way something works or just want it to do something different, odds are pretty good that there is an to do it with. For example, did you know you can switch our your keyboard (try either Google Keyboard or Swiftkey, both really great alternatives to the stock keyboard). You can switch out the way your home screen looks/feels by using a different launcher like Nova or Apex (or try an easier version by downloading Buzz Launcher, which allows you to download customized home screen layouts created by users). Good luck and have fun. Welcome to Android.
