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 is the most popular custom ROM around, with official support for dozens of devices and a huge community. The project relies on the work of contributing developers, which means phones can just easily be dropped as they are added. Since we last covered LineageOS, a few new devices are now supported, while a handful of fan favorites have been dropped.
