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 wants performance and some wants speed, some want looks and some want features. Putting them altogether in one ROM can cause a Lag, performance issues and bugs. But Custom ROM is basically designed for either Looks or Performance and Custom ROM gives speed and great performance with Tweaks and System Tools.”
