About Stock ROM

There are two types of ROMs in Android ecosystem. As I mentioned above one is Stock ROM or the Firmware which comes preinstalled with any Android device and the second one is Custom ROM or commonly known as ROM. Custom ROMs are developed by third-party developers for a specific device. Most of the Custom ROMs are feature-packed and fast which makes them a better alternative to the stock firmware.
