What Samsung could've done with TouchWiz (Mockup)
This is my vision on what Samsung should've done with TouchWiz for the Galaxy S4. The new TouchWiz is an OK upgrade from the previous version, but Samsung could've done so much more to make it look nicer and cleaner.
All these mockups are in 1080p resolution, so it would look sharp on any device. :) Make sure you click on "via dl.dropboxusercontent.com" to get the true 1080p resolution. Clicking on the image won't give you the full resolution.
Just for some contrast, this was a mockup I did a year ago: http://www.theverge.com/2012/5/13/3018517/ics-rom-mockup
Tell me whatcha think and what I can improve on. Once I have the time, I plan to make more in the future, so bookmark this page if you want to see the progress. :)
