The Android 12-based One UI 4.0 update for the Galaxy Note 20 and the Galaxy Note 20 Ultra comes with firmware version N98xUSQS2EULF. Right now, the update is available on Comcast and Xfinity Mobile's networks, but it could expand to more networks over the next few days. Unfortunately, the update still uses the December 2021 security patch and not the latest January 2022 patch.
If you are a Galaxy Note 20 or Galaxy Note 20 Ultra user in the US, you can check for the new update by navigating to Settings » Software update and tapping on Download and install. You can also download the latest firmware file from our firmware database and flash it manually.
The Galaxy Note 20 was launched with Android 10-based One UI 2.5. It received the Android 11-based One UI 3 update in late 2020 and the Android 12-based One UI 4.0 update a few days ago.
