Hey there, ! We see you're having trouble updating your Samsung Galaxy S21 Ultra 5G to the latetest software verison Android 12.


Let's make sure you've met the requirements necessary for performing a software update. You can view these details below:

  • Make sure you’re in the U.S. and on our wireless network.
  • You can download the update via Firmware Over the Air (FOTA).
  • You must connect your device to Wi-Fi to download the update.
  • Although there should be no impacts to settings or data, we recommend backing up your media files to an SD card, a computer, or using a favorite application, prior to upgrading the software.

After confirming that you meet the criteria, follow these steps to update & verify your software.

  1. Make sure your device is fully charged and connected to Wi-Fi.
  2. Swipe down from the Notification bar and select Settings.
  3. Scroll to and select Software update, then Check for updates.
  4. Follow the on-screen prompts to download and install the update. The device automatically restarts once the new software successfully installs.

If you're still experiencing difficulties updating your device then Troubleshoot & Resolve to fix the software update error.


Lastly, if complications still persists, we advise to contact Samsung Support for a pushed update to your phone.


We hope these tips do the trick and thank you for confiding in the AT&T Community Forums!
