The firmware for the Galaxy Z Flip comes with version F700WVLU4FULA and is currently available on Rogers, Bell Mobile, Telus, and Videotron’s networks, while the Galaxy Z Flip 5G’s firmware comes with version F707WVLU2EUL9 and is available on almost all networks.
In addition to the usual Android 12 and One UI 4 features, both builds come with the December 2021 Android security patch, which is a bummer since some Samsung smartphones started receiving the February 2022 security patch last month.

Samsung is also seeding the One UI 4 update for the unlocked Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra units in the US. It comes with firmware version G98xU1UEU2EVA2 and bumps up the Android security patch level on the S20 trio to January 2022.
