When Did Nothing OS 4.0 Roll Out?

Nothing began releasing OS 4.0 in November 2025. The first device to receive it was the Nothing Phone (3). After that, the update slowly reached other models like Phone (2), Phone (2a), and the Phone (3a) series.

In December, CMF devices also started receiving the update. Some users experienced delays because the rollout was paused briefly to fix issues. However, the process resumed shortly after.

Now, Nothing OS 4.1 is also being introduced, mainly on newer devices like the Phone (4a) series. Older phones are expected to receive it soon. In simple terms, OS 4.0 is almost fully rolled out, while 4.1 is gradually expanding.

Most recent Nothing phones are included in this update. Here’s a clear list:

Premium Models

• Nothing Phone (3)
