But why would anyone goes 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 wants looks, some wants features. Putting them all in one ROM can cause Lag, Performance issues and bugs. But Custom ROM in basically designed for either Looks or Performance and Custom ROM gives speed and great performance with Tweaks and System Tools.”
