Developer "Spc_Hicks09" has been busting out lots of Rom ports for the Verizon Galaxy S4. Thanks to his work their are plenty of rom choices for our device! Carbon Rom is based on AOSP vanilla Android! That being said all of the stock touchwiz functionality is completely removed from this rom. Team Carbon is dedicated to fast, stable, and feature filled roms. This rom has been built with Linaro optimizations for extra speed and performance. The features list is pretty long so we won't list everything here. Some main features include Halo, BAMF theme engine, customizable quick settings, auto-hide status bar, carbon rom stats, carbon battery, wake device with power home or both, gesture lockscreen, tile colors, and much more!
