Ok so i'm so stuck on whether to go for the nexus 5 or s4, what i need is a fast phone with good battery life and memory a lot to ask i know. The way i look at it is the downside to s4 most of the ram is used up by touchwiz so does installing a better rom free up more ram? the downside i see for nexus is no SDcard support for extra memory but i may be able to manage with the 32gb nexus gives, also the removable battery of the s4 is a big plus for me so i'm stuck on which one to pick
