Android is a fantastic mobile operating system, and continues to become one of the biggest forces in mobile software out on the market. As is the nature of Android, everybody seems to want a slice. Whilst this means that we, as consumers, have a large product base to choose from, it also means we get lumbered with a huge amount of manufacturer bloatware. Without a doubt the worst feature of the Samsung Galaxy S4, in my opinion at least, happens to be the user experience that Samsung TouchWiz provides. HTC Sense 5 isn't any better either, and don't even get me started on Motorola's MOTOBLUR from some years back.
