LineageOS is the most-used custom Android ROM around, but that doesn't mean there isn't room for others. Paranoid Android was a popular choice back in the KitKat days, and while the ROM returned in full force with Nougat builds in 2017, there hasn't been much news since. Now the project is back (again), touting Android 10 builds for nine phones so far.
LineageOS 17.1 is the latest release of the popular custom ROM, based on Android 10. The LineageOS project was already providing daily builds for over 60 phones and tablets, but in the time since we last covered the ROM, a handful of additional phones have been granted official support.
The Essential Phone has been around since 2017, but surprisingly, it has never officially been supported by the popular LineageOS custom ROM. The phone is still receiving updates from Essential at a rapid pace, so there hasn't been much of a need to replace the stock software, but now you can install official LineageOS builds if you so desire.
