Samsung may not release the Android 5.0 Lollipop update for the Galaxy S4 until 2015 but users can already check out what is in store for them. A new leak and comparison video show how the Samsung Galaxy S4 runs on Android 5.0 Lollipop versus when in Android 4.4.2. As Google rolls out its next big Android update, some analysts are calling it the best thing that may have come to Samsung's TouchWiz UI. Does it really deliver?

In an exclusive report by SamMobile, Galaxy S4 owners should prepare for a bigger update compared to the firmware on the Galaxy S5. Aside from all the promised features of the new Android update, S4's TouchWiz UX will be replaced similar to the newer edition of its successor.

To further demonstrate how much S4 users stand to gain, SamMobile provides an exclusive comparison of the device running on two versions of the Android: 4.4.2 and 5.0. Despite similarities in the appearance of the home screens, reports note the redesigned UI to be one of the biggest changes to hit Samsung devices this year.

Forbes calls Lollipop's Material Design to be the best of its attributes. Through the new update, Google laid out the rules for developing the Android user interface. It is both considered brilliant and brave encouraging a more coherent approach among manufacturers. There is considerable attention over the Material Design because Google finally went beyond changing the look of the interface but also on how to interact.

Navigation is both educational and consistent as people can check out an action's point of origin and proceed to the next step or transition. Android made sure to incorporate physical properties to its UI layer, animation and button press for enhanced navigation.

The UI is intuitive allowing users to use Android with quick response time. Material Design changed the game for the overall Android user experience. This pushes Android to having more than just a superficial and now a more functional design.
