Galaxy S3 Custom ROM- Omega ROM

One of the best things about the openness of the Android platform is that if you’re unhappy with the stock OS, you can install one of many modified versions of Android  on your device. It allows users to customize every facet of their phone while iOS doesn’t, even with powerful theming systems and Android enthusiasts are often heard installing “Custom ROMs” on their devices.

Beyond simple fixes, custom ROMs can also open a whole world of new possibilities for your Galaxy S3. Custom ROMs can also include other cool features, like overclocking, themes, private browsing support, and so on.

What is the different between Galaxy S3 Stock Rom and Custom ROM?
