I like the way apps work in android better than iOS they seem to have more freedom to work (things like Tasker being able to work with multiple apps, and Google Play Music able to run in the background and sync without me having to open the app every once in a while) .

As for your settings maybe you just aren't thinking about the android way, for changing the wallpaper you should probably be pressing the menu button on the home screen much like you would right click on the desktop in Windows.
