Custom ROMs have been giving a new look to Android devices thanks to the talented developer community. They add a change of appearance, improved performance, and new features to your device. A new ROM has been released for the Samsung Galaxy S3 GT-i9300 that is definitely worth checking out.
The new ROM is called the ROMOW EXTREME ROM. It was developed by XDA Developers’ member mowo. This new ROM has been deodexed and zipaligned, with the addition of BusyBox, Superuser and other tweaks that give a boost to battery life/performance. It has an improved task manager, with an extended power menu and many other features. The ROM has removed the bloatware (unnecessary applications) as well, which means it occupies less space on the device.
