What is a custom ROM?
Android is open source, so developers can take its code, add features, and build their own operating system images for Android phones and tablets. This new operating surface with “extra” features is known as a custom ROM.
A stock ROM is the version of the phone’s operating system that comes with your phone when you buy it.
A custom ROM is a fully standalone version of the OS, including the kernel (which makes everything run), apps, services, etc – everything you need to operate the device, except it’s customized by someone in some way.
