Samsung Galaxy S3 owners in the UK and other parts of the globe has received the Android Jelly Bean 4.3 update only for many users to experience bugs and operating problems. Those who wish to sidestep the bugs and problems can consider updating to Android 4.4 KitKat custom ROM. The ROM caters specifically to Samsung Galaxy S3 GT-i9300 version offering generally more stable interface than the official Android 4.3 Jelly Bean firmware.
The custom ROM comes from the OmniROM team. Auto Mobile reported that it offers more stable performance compared to the official Jelly Bean. However, users may have to deal with a messy video playback and camera. For those who do not mind the drawbacks of the custom ROM, here are the installation steps:
