Third-party firmware on Android 10

On September 4, Android 10 was released, however, the system is available for a limited number of smartphones. Among them, of course, Google Pixel, as well as Redmi K20 Pro, Essential Phone and OnePlus 7. How do owners of smartphones of other models see with their own eyes the "chips" of the new version of the "green robot"? Everything is simple - install third-party system firmware.
At the moment, at least three third-party Android 10 firmwares are available. For smartphones Redmi 5 Plus, Redmi Note 5 and Pocophone F1, enthusiasts have made POSP firmware, which allows you to fully appreciate the new OS. The only negative - sometimes they report problems with the fingerprint sensor.
 For Xiaomi Mi 6, LineageOS 17 firmware is suitable, with the exception of difficulties with Bluetooth, it is a fully functional option.
And finally, the owners of Xiaomi Mi 8 will need to download the Pixel3 ROM firmware, in which all functions except the camera and fingerprint scanner work.
