I can see that the bottom "fixed" row of apps on S4 (which remains in place when you swipe between different homescreens) contains 5 apps. But for the rest of the homescreen, each row only contains 4 apps. Does anybody know if it's possible to insert an extra app into those rows? In other words the maximum number of apps on the stock home screen would then be 5 rows, each containing 5 app icons i.e. 25apps ?
