What is Stock ROM?
Stock ROM is an operating system developed by smartphone manufacturers to attract users. Every smartphone has its unique interface and features in its stock ROM. It differs from one brand to the next, as each gadget is custom-designed by the maker. It comes pre-installed in your device by the manufacturer when you purchase it. Some companies utilize Google’s stock operating system, while others created a Stock Rom using their own operating system.
If a stock ROM is open-source such as Android, code can be accessed by the developer, edited, recompiled, and re-released for another android or Custom ROM.
