What is LineageOS?
LineageOS is a free, community built, aftermarket firmware distribution of Android based on the Android Open Source Project.
It’s basically custom firmware that can be installed to replace the stock (manufacturer- provided) Android on your device, giving you longer life out of a device, added features you’d never get at all otherwise and often less bloatware (extra apps provided by the manufacturer or carrier).
Origins and History

The sequence continued in the style of CyanogenMod#Version numbering (e.g. LineageOS 14.1 is based on Android “Nougat”9)
Many devices have had official builds supported; however, older or less active devices may never get official support.
