Earlier this month, nothing OS 4.0 was announced as a company’s skin based on Android 16, which was released by Google in June. Today, the first open beta OS 4.0 for nothing is available at the end if you want to become an examiner.
It is currently installed on the phone (3), phone (2), phone (2A), and phone (2A) plus, phone (3A) and (3A) Pro, but nothing will be found in October, but in October, there will be nothing OS 4.0 slices. If you want to participate in the open beta and have one of these tools, you should first be on the latest stable release.

If you are, you need to install an APK that is connected to the official community post of nothing in the case here. It will appear a new item in the Settings> System, which is called anything beta hub. This is where you need to go to sign up. Once you get registered, go to the update.
As it is a beta release, bugs will essentially exist, so as usual we should take care against doing so on your main device. Nothing encourages you to share the response to help you refine the experience. You can do this through Settings> System> Feedback.
