Lol I think you got it back wards buddy. GE on my s4 has no flaws. Everything works. CM loses audio while receiving calls every couple of mins or so. Plus I got two force closes immediately on cm while I have zero so far in 6 days of GE.
Indeed. CM is a solid ROM in its stable form but it's still strictly nightly-only for the GS4 right now. On the other hand, the GE ROMs are literally designed for the GS4's hardware by Samsung themselves.
