Samsung's Android 12-based One UI 4.0 beta brings a plethora of new features that you can start testing right away. However, as is the case with beta software, there are a few things you need to know before you start. Keep the following points in mind:

1. A compatible Samsung phone is required

Currently, Samsung S21, S21 Plus, and S21 Ultra are the only devices for which the One UI 4.0 beta has been released. If you are a Samsung user but own another phone, unfortunately you will not be able to enjoy the One UI beta at this time. However, don't worry, as we expect more devices to beta to come over time.

2. You will need the SIM card from the country of origin

Depending on where you purchased your Galaxy S21 device, you will need a SIM card from the same country. For example, users living in India must have an Indian S21 and a local SIM card for beta registration. Although you can try another country's SIM card, it didn't work very well for us.

3. Make sure to create a data backup

We cannot stress this enough. Make sure to create a full backup of your device data and other sensitive information before proceeding. While the One UI 4 beta should install without any data loss, it's always best to exercise caution and back up your precious data.

Since beta software is a way for developers to test their first creations, chances are you will encounter errors and bugs. Rest assured, any bugs while using One UI 4.0 are completely natural and will be fixed as future versions are released. However, this also means that if you are using your Galaxy S21 device as a daily driver, you should not opt for the One UI 4 beta. We suggest you wait for the official release as it will be a stable release.

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