I just want to say if anyone is looking for a light and responsive rom. this is it. now the optical, and proximity sensors don't work. wifi calling doesn't work. and because it's not touchwiz the stock GS4 samsung apps wont work. but if you can do without those and want the fastest most lag free OS... check it out.. install the zip from SD with CWM then install the 4.4 (ONLY) Gapps any other Gapps wont work. I'm running it with Nova launcher prime and it's the fastest ROM I've ever seen. no more of that android lag that all droids have.
