Whats NUU Stock ROM and its Advantage
The Stock ROM (Mobile OS) is the Most Stable ROM released by the device manufacturers depending on the device model and Android version. However, the Stock ROM don’t offer many customizations or features for the device.
While in general third-party firmware (Custom ROM) has system bugs and stability issues.

But whenever you switch to Stock ROM, you can quickly fix them all.
