Installing a custom ROM on your Samsung Galaxy Grand Neo will replace the stock Android operating system that comes with your device given to you by Google and Samsung. There are many reasons to install a custom ROM on the Grand Neo device. The most popular reason to install a new ROM on any Android is to update the operating system when your software updates are slowed. You might get a third-party developer making a custom ROM for your device that is based on Android 5.1 Lollipop when the only official firmware for your device is still Android 4.4.4 KitKat.

Another popular reason to install a custom ROM is to replace the manufacturers skin with stock Android so you can use the Android operating system the way Google intended. The operating system you see on your device when you open it out of the box and accept official OTA notifications is heavily influenced by Samsung with Samsung apps and features. That’s on top of the operating system Google gave you with Android. A custom ROM can allow you to remove that manufacturer (Samsung) skin completely.
