Developers on the XDA forum have successfully fitted Android 4.1 (Jelly Bean) to the international version of the Samsung Galaxy S3. This comes after news from SamMobile that the South Koreans were officially testing Android 4.1 for the S3. The Galaxy S3 was launched with Android 4.0.4 (Ice Cream Sandwich).

The XDA developers have claimed success porting an AOSP ROM, dubbed LiquidSmooth ROM for the S3 model number i9300. Available key features include faster and more responsive User Interface (UI), customisable center clock, improved battery icons, native overclocking/undervolting performance and more. The LiquidSmooth ROM is in the early stages of its development and some features, like the camera and Google Now, have been reported as not functioning.

Check out the steps to install LiquidSmooth Jelly Bean ROM for the international version of the Samsung Galaxy S3. IBTimes UK warns users the ROM is compatible only with the international version and not any other variants. In addition, we recommend users back-up all important data and settings.
