Samsung Galaxy S3 is the most anticipated Android smartphone manufactured till date, adding more than 9 million pre-orders to its portfolio. Popular smartphones always demand for the attention of developers. And those things have started happening as CynaogenMod team has released the first custom ROM for Samsung Galaxy S3, even before the smartphone has hit U.S. shores.

Restless folks at CyanogenMod have opened doors for Galaxy S3 owners to test the first nightly (equivalent to Beta mode) build of CyanogenMod 9 on the smartphone. The new build is superfast, lightweight and adds some bits of awesomeness to Galaxy S3. However, you will not be getting the so-called "Inspired by Nature" interface in custom builds. The nightly build is based on Vanilla ICS theme, which is similar to the one Samsung utilizes in Galaxy Nexus.

The nightly build is light weight and significantly improves performance of the smartphone. Many users are replying back that the battery life has also increased after flashing the new ROM on Galaxy S3. However, the ROM is still far away from being perfect. The custom build have following issues in it:

•  Problem with camera flash (sometime laggy and sometimes does not work)
•  FM Radio is offline
•  LED notification will be off while the smartphone is charging

In case you are ready to sacrifice these features, the CyanogenMod 9 build is all yours to flash on Galaxy S3. However, you will need to root the device first. And we did like to remember you that rooting your smartphone voids warranty.

CyanogenMod 9 Nightly build is available for downloads on XDA forums. The ROM will only work on international version of Samsung Galaxy S3, codenamed GT-I9300. For 4G LTE variant of Galaxy S3, CyanogenMod folks will be developing a separate ROM.

If you are not familiar with installing Custom-ROMs on Android smartphone, you need to be warned that you may brick your phone doing so and it could be very difficult (and time consuming too) for you to return back to the stock level.
