Introduction: A New Chapter for Nothing Phone 3a Users
Nothing OS 4.0 Beta Brings Major Updates to the Phone . Nothing has officially rolled out the Nothing OS 4.0 Beta update for the Phone (3a) series, marking a major milestone for the company’s mid-range smartphones. After teasing several design and performance improvements, the update is finally here for beta testers and early adopters in India and other global markets.
If you’re wondering what’s new, what the buzz around pre-installed apps is about, and whether you should install it now or wait, here’s everything you need to know about the Nothing Phone 3a OS 4.0 update.
What Is Nothing OS 4.0 Beta?
Nothing OS 4.0 Beta is the latest version of the company’s custom Android skin, built on Android 16. It focuses on improving speed, smoothness, and design harmony across the Nothing device ecosystem.
According to Akis Evangelidis, co-founder of Nothing, this beta update introduces “a refined visual experience, more cohesive animations, and deeper integration between hardware and software.” The company aims to make the Nothing Phone 3a series feel even more fluid and minimalistic than before.
Key Features in the Nothing OS 4.0 Beta Update
1. New Visual Design
The interface has received subtle tweaks—sharper icons, cleaner typography, and smoother transitions. The signature dot-matrix aesthetic remains, but animations now feel more responsive and consistent throughout the system.
2. Improved Performance
Under the hood, Nothing claims better memory optimization and app launch speeds. Early testers report noticeable smoothness in multitasking and reduced app crashes.
3. Pre-installed Apps: The Controversy
One of the most talked-about additions in the Nothing OS 4.0 Beta Phone 3a series is the inclusion of a few pre-installed apps. While some users welcomed them for convenience, others raised concerns about “bloatware.”
Evangelidis clarified that these pre-installed apps are selective partnerships aimed at improving user experience and will be easily removable in the stable release. This move indicates Nothing’s attempt to balance minimalism with utility.
4. Lock Glimpse and Privacy Controls
The update also introduces the Lock Glimpse feature—a smart notification system that briefly shows relevant updates without unlocking the phone. Along with that, users get enhanced privacy settings for app permissions and tracking.
5. Battery and Stability Upgrades
Battery optimization algorithms have been fine-tuned. Many beta testers report better standby times and fewer heating issues during heavy usage.

Nothing OS 4.0 Beta Brings Major Updates to the Phone
India remains a key market for Nothing, and the Phone 3a series has been particularly successful among users who love its minimalist design and clean Android feel. The Nothing OS 4.0 update India rollout began with a staged beta, allowing select users to test and report bugs before a stable public release in November 2025. Indian users are already sharing early impressions on social media—most praising performance gains and visual refinements, while some question the necessity of pre-installed apps.
Should You Install the Beta Version?
If you enjoy experimenting and can handle occasional bugs, the Nothing OS 4.0 Beta is worth a try. It gives you early access to features like Lock Glimpse, improved privacy tools, and a faster UI. However, if you rely on your phone for daily work, you may want to wait for the stable update. Beta versions sometimes include glitches with camera, battery, or app compatibility.
