LineageOS is the most popular custom ROM around, bringing new Android updates to abandoned phones, and a stock-like experience (with or without Google software) to newer devices. The last time we covered the project, it added support for a handful of phones from Huawei, Sony, Xiaomi, and OnePlus. Since then, many more devices have made their way to the official roster.
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 one of the most popular custom Android ROMs available, with over two million active installations. The project officially ended support for the 14.1 (Android 7.1) branch a few days ago, in preparation for LineageOS 16. The 16.0 branch is finally rolling out, and it's bringing Android 9 Pie to dozens of phones and tablets.
