Check Out the Difference between Stock ROM and Custom ROM.
What is Custom ROM?
Android is an open-source platform that allows developers to build their own operating system images for Android phones and tablets from scratch. This custom app is known as Custom ROM, which replaces the Android operating system (Stock ROM) that comes with your phone or tablet. The Custom ROM comes with a kernel, making it a fully standalone operating system. Some developers in the Android community customize the Android OS by removing all unwanted apps, providing a pure Android experience with no carrier-installed or OEM apps.
The Custom ROM is regularly updated by the community and developers, fixing all the related bug reports. It also allows you to experience the latest Android OS, even if the update is not available for your smartphone.
