Hello everyone. Sorry this was uploaded so late but I couldn't stay up until 1:00 AM to grab the firmware as it was released to the public, as I had a very busy and important day to prepare for. Anyway, the final One UI 4.0 firmware for the S21 and the S21 Ultra is now available to download in the firmware hub! Flash these as you flashed the US FW in Part 2 of the One UI Beta guide.
Enjoy the stable release!
