This update is expected to bring a number of new features to the Samsung Galaxy Note20 Ultra, alongside a redesigned UI for users. The One UI 3.0 update for the AT&T is rolling out over the air, and users can see this update when they go to Settings > Software Update.

     This update comes a couple of weeks after Samsung rolled out the Android 11 with One UI 3.0 for the Samsung S20 series. As with most software updates, it is advisable to download this update with a Wi-Fi connection, also, don’t forget to back up your data prior to the installation process. At the time of this article, the South Korean company is yet to reveal what carriers would get this update next, but we expect to see a number of North American carriers get this update for their Note20 devices soon. There is no set timeline yet telling when this update will be available for download to users of the Samsung Galaxy Note20 Ultra 5G outside of North America, with certain sources speculating a January update for other regions.   References
