How to install One UI 4 Beta on Samsung smartphones

In anticipation of the global rollout of One UI 4 based on Android 12, Samsung has launched a firmware beta testing program that will allow Galaxy S21 series owners to participate to troubleshoot bugs. This article will show you how to download and install it on your smartphone.

Before you start, there are a few important things you need to know:

  • The beta testing program is open to owners of Galaxy S21, S21 + and S21 Ultra smartphones. Currently, One UI 4 is available for US residents, but in the coming days, it is planned to deploy the firmware in the UK, India, Germany and in some countries of the European Union (EU).
  • Downloading the beta version of One UI 4 will not delete files and installed applications on your smartphone. However, it is recommended that you back up all important data before installing updates.
  • In addition, you may encounter app compatibility issues and various bugs on Android 12.
  • After you take part in the beta test of the One UI 4 shell and install the software on your smartphone, it will automatically receive updates for all future test versions.
  • You can at any time refuse to participate in the beta testing program and roll back the device to Android 11 One UI 3, but this action will completely delete all your data from your smartphone.

  • You need to download and install the Samsung Members app on your Galaxy S21, S21 +, or S21 Ultra.
  • Opening the Samsung Members app, you will see a window where you can join the One UI 4 beta testing program. If the window is not available, check in a few hours.
  • You will be prompted to sign in to your Samsung account.
  • After registering for the beta program, go to your phone’s Settings, then select Software Update and click Download and Install. Your smartphone will check for software updates and the One UI 4 beta firmware based on Android 12 will appear for download.
  • The beta version of One UI 4 weighs about 2-3 GB, so make sure your smartphone is connected to a fast Wi-Fi network and at least 50 percent charged.


After you become a participant in the beta testing of the One UI 4 firmware, all new software features will be available to you, on which you can leave feedback on the work of the shell. Since One UI 4 is under development, Samsung is taking into account all feedback from beta testers and finalizing the software. There will be updates every few weeks with new features and bug fixes, so your experience will improve One UI 4 based on Android 12.
