So, what is the Lineage OS? It is a free and open source operating system for smartphone and tablet computer Android distribution. It has a really long story of development, which starts from CynogenMod. CynogenMod is a custom ROM for Android devices. It’s free and it can extend the capabilities of your device and themes, improve privacy functionality and all sorts of UI/UX tweaks. And the best part is that in a rooted device, the installation of CynogenMod is very easy. It could be found in millions of device. In fact, in a number of handsets, you can find it preloaded. But Cynogen Inc. has officially the support for mod. And it affects its open-source version too. The good news is that its predecessor is Lineage OS which is very successful till date.
From the viewpoint, Lineage OS and CynogenMod are the two sides of the same coin. Lineage OS has its own community from which we have seen a slew of development, covering more than 200 phone models.
