As noted by Redmond Pie, CyanogenMod 10 is the first experimental custom build and therefore it is full of major broken features, has leggy UI and, as such is unsuitable for daily use. But still CyanogenMod is quite popular among users as it receives constant support from the community.
The custom ROM allows owners of old Android phones to try their hands on the latest version of Android and enables owners of the latest smartphones to ditch their smartphone manufacturer's custom skin for a more vanilla Android experience, said the report.
Although CyanogenMod 10 is a rough first version, those who want to see what the future holds can refer to the installation guide given below.
Before starting the process, you must root your device. The ways to root it will also differ, based on the different variants of the Galaxy S3 smartphone. Click on the links [Redmond Pie] below, depending on which variant you are using, for a detailed guide for rooting the Galaxy S3.
