A ROM installed by the manufacturer of a phone is known as STOCK ROM.There are basically two types of ROMs available in the market Android Stock Rom and Android Custom Rom.Android is customizable to an extensive degree. When a manufacturer builds a Stock ROM the basic requirement to keep the smart phone running are the device drivers. The remaining part of the ROM is decided on what apps to be installed and how to have the interface modified to suit customer needs.In other words it can be termed as functional and cosmetic changes. Stock Rom Come with manufacturer oriented premium apps like live wallpapers, Music Player, widgets etc. These apps are especially designed by the manufacturer to enhance the android user experience. Every different vendor has a different set of premium apps for every new device.
To install a Custom ROM, a user needs to root a device and Rooting voids warranty. This is a simple reason why users stick to stock ROM’s during the warranty period. By default android possess its own cool form factor, but manufacturer always want to load android with more premium features. Although custom ROMs are free to install but premium features like flip clock on lock screen and swipe keyboard will be chargeable. Custom launchers are a good example for this. Samsung phones come with touchwiz UI and can be installed with any launcher, but a phone having a custom rom will not be able to install premium launcher like the touchwizUI.
