Nothing’s first-ever b-series smartphone, the Phone (4b), has officially arrived today. While the fresh design and the Snapdragon 6 Gen 4 chip are grabbing the headlines, there is one crucial detail every savvy buyer needs to verify before hitting pre-order: the software update policy.
Here is exactly what you can expect from the Nothing Phone (4b)’s software lifecycle and why it actually matters.
The Software Promise
Nothing has established a consistent standard for its mid-range smartphones. Out of the box, the Phone (4b) runs on the clean, bloatware-free Nothing OS 4.1 (based on Android 16).
Based on Nothing’s established roadmap for this tier, here is the expected support window:
3 Years of Major Android OS Updates: This means your phone will be supported all the way through Android 19 in 2029.
4 Years of Security Patches: These bi-monthly updates will keep your device secure against vulnerabilities through the summer of 2030.
Can You Trust Nothing to Deliver?
In the Android world, a promised update and a delivered update are often two different things. However, Nothing just proved they walk the talk.
Just days ago—in early July 2026—Nothing officially concluded software support for the original Nothing Phone (1). The company successfully fulfilled its exact promise from 2022, completing the major upgrade to Android 15 and delivering the final four-year security patch right on schedule.
This track record is a massive green flag for Phone (4b) buyers. When Nothing commits to a four-year lifecycle, history shows they follow through.
The Verdict
For a phone targeting the affordable segment, a 3-year OS and 4-year security update policy is the perfect sweet spot. It guarantees you will get years of Nothing’s signature dot-matrix aesthetic, new widgets, and performance tuning without being forced into a premature upgrade.
If you are looking for a reliable daily driver that won’t be abandoned by its maker next year, the Phone (4b) has the software pedigree to back it up.
