Install One UI 4.0 Beta on Galaxy S21 Phones (2021)

While the guide below will teach you how to install One UI 4.0 beta on your Galaxy S21 devices, we will also cover a few important points you should keep in mind before you move forward. If you would rather just check out the installation process, use the table below to jump to the section.

Things to Keep in Mind Before Upgrading to One UI 4.0

Samsung’s Android 12-based One UI 4.0 beta brings about a plethora of new features that you can start testing right away. However, as it is with beta software, there are a few points you should be aware of before you begin. Keep the following points in mind:

1. A Compatible Samsung Phone Is Required

As of now, the Samsung S21, S21 Plus, and S21 Ultra are the only devices for which the One UI 4.0 beta is out. If you are a Samsung user but own any other phone, sadly, you won’t able to experience the One UI beta right now. However, don’t fret since we expect beta support for more devices to arrive as time passes.

2. You Will Need the Native Country’s SIM Card

Depending on where you bought your Galaxy S21 device from, you will need a SIM card originating from the same country. For instance – Users living in India should have an Indian S21 and a local SIM card for the beta registration. While you could try another country’s SIM card, it didn’t work that well for us.

3. Be Sure to Create a Data Backup

We cannot stress this enough. Be sure to create a full backup of your device’s data and other sensitive information before you proceed any further. While the One UI 4 beta should install without any data loss, it’s always best to err on the side of caution and backup your precious data.

4. One UI Beta Will Be Unstable

Since beta software is a way for the developers to test out their early creations, there is a high chance you will encounter some errors and bugs. Rest assured, any bugs while using One UI 4.0 are completely natural and will be patched as future builds come out. However, that also means that if you use your Galaxy S21 device as a daily driver, you should not go for the One UI 4 beta. We suggest you wait for the official release as it will be a stable one.

One UI 4 Beta Supported Countries

As per the information available with us, Samsung has already released the One UI 4.0 beta for the following countries this year:

IndiaSouth KoreaChinaGermanyPoland United States (US)United Kingdom (UK)

While we don’t think the South Korean giant plans to extend support to more countries in 2021, you can always wait and see if that changes.

Since the Samsung One UI 4 beta is available through official Samsung Members (Free) itself, we will be using that.
