LineageOS is the successor of CyanogenMod, a popular custom ROM which brought the stock Android experience to all Android phones for many years. After CyanogenMod went down, LineageOS took its place and developers continued to develop new builds for many mobile devices. Right now, the latest version of the ROM is LineageOS 15.1 which is based on Android 8.1.0 Oreo. This build is available on many phones, and right now it can be installed on OnePlus 6 too.
The OnePlus 6 is the newest phone from OnePlus. It has a great price and top of the shelf specifications that make the phone attractive to many users. It comes with Android 8.1.0 out of the box, so you do not have to wait for any updates when you turn on the phone for the first time.
While the OnePlus 6 is already running on Android 8.1 which is the same version as LineageOS 15.1, the later offers many features and increased performance which are not in the stock build. For example, LineageOS 15.1 includes Ambient Display, RGB color calibration settings, gestures, extreme power saving modes with different performance profiles (Performance, Balanced, Efficiency, Power Save), modified Quick Settings menu, settings to modify the UI and apps such as AudioFX, Trebuchet launcher, Eleven music player, Snap camera and much more.
