If you are one of the many Android users that are in the ROM community, then you have likely heard of Lineage OS but you’d probably be surprised how many compatible Lineage OS devices there are.
Lineage OS came into being after Cyanogen Inc. attempted to commercialize CyanogenMod and miserably failed in its efforts to do so.
Lineage OS is an open-source operating system based on Android, with its own open-source community.
You might even need to track down bootloader unlock codes for certain devices, so make sure to do your homework beforehand.
As long as enough people make enough noise, there are bound to be developers that will listen and help make a Lineage OS ROM for that device.
Odds are that there are unofficial versions of Lineage OS and other custom ROMs floating around for your device, but it does not hurt to look around to make sure.
