But why would anyone go for a Custom ROM instead of staying on the Stock On, allow me to explain… “Stock and Official ROMs are good, but they are created with keeping in mind the demands of all, some want performance and some wants speed, some want looks, some want features. Putting them all in one ROM can cause a Lag, Performance issues and bugs. But Custom ROM is basically designed for either Looks or Performance.  Custom ROM gives speed and great performance with Tweaks and System Tools.”
