The tech world loves hype — and Nothing as a brand knows exactly how to create it. The company’s clean design philosophy, quirky transparency aesthetic, and unique interface approach have made it stand out in a sea of generic Android skins. But here’s the real question every Nothing Phone user is thinking right now:
Is Nothing OS 4.0 worth the upgrade, or is it another cosmetic update pretending to be revolutionary?
This article digs deep into the new version, examining performance, everyday usability, gaming impact, customization, bugs, stability, battery management, software philosophy — everything a real user would care about.
What’s New in Nothing OS 4.0? A Quick Overview
Before diving into pros and cons, let’s look at the key upgrades bundled with Nothing OS 4.0:
- New customizable widgets and home-screen layouts
- Improved monochrome and “minimal distraction” UI
- Optimized battery algorithms
- Better RAM and cache handling
- Redesigned Quick Settings panel
- Enhanced privacy controls
- More control over notifications & status indicators
- Camera improvements via pipeline optimization (not new hardware)
- Refined animations, transitions, and haptics
On paper, it sounds like the biggest update Nothing has rolled out so far. But is the experience as good as the spec sheet?
Performance and Speed – A Noticeable Upgrade?
One of the most widely discussed aspects of Nothing OS 4.0 is performance.
Apps open faster, RAM management is much better, and background tasks no longer slow the interface as dramatically as before.
Where it really improves
- Animation smoothness increases and even budget models feel snappy
- Multitasking holds more apps in RAM without refreshes
- Thermal throttling is reduced during long sessions
Benchmarks aside, the real-world upgrade is visible — scrolling is smoother, and the phone feels more “alive.” If you hated random stutters in Nothing OS 3.5, you will definitely appreciate the upgrade.
Where it still struggles
- Heavy games heat the phone slightly more than on stock Android
- App-to-app transitions, while fluid, aren’t as instantly sharp as Pixel UI
So the upgrade isn’t a miracle — but it is a legitimate quality-of-life improvement.
Battery Life and Charging – One of the Best Reasons to Upgrade
Here’s where Nothing OS 4.0 genuinely shines.
The new “Intelligent Adaptive Battery Algorithm” learns user patterns and aggressively restricts unused background apps. For most users, this translates to:
| Scenario | Battery Before | Battery After |
| Normal usage | ~1 day | ~1.3 – 1.5 days |
| Gaming | Hands heats, drains fast | 8–12% longer battery |
| Idle | ~5% drop overnight | 1–3% drop overnight |
Charging animations and thermal management are also improved — the phone no longer heats as much while charging.
Downside?
Some users might notice delayed notifications for rarely used apps due to aggressive battery control. If you rely on instant alerts from apps like Telegram, banking or education portals, you may need to whitelist them manually.
Customization and UI — A Real Identity or Just Aesthetic Flex?
Nothing has always tried to do “different but minimal.” With Nothing OS 4.0, the interface gets an identity that feels polished, not experimental.
New customizations include
- More widget designs
- Lock screen layout editing
- Adjustable quick-settings tiles
- New monochrome theme packs
- New typography and icon size options
The OS now feels balanced between simplicity and personality. It’s not as bland as Pixel and not as overloaded as One UI.
But it’s not perfect
Some advanced customization options (like third-party icon packs, gesture mapping, and full theming via Material You) are still not fully supported.
Camera Performance – Real Upgrade or Marketing Speak?
The camera upgrade in Nothing OS 4.0 is software-driven. There are improvements, but they differ depending on your model.
Actual improvements
- Faster shutter capture
- More accurate skin tone reproduction
- Better low-light noise handling
- Sharper ultrawide and portrait mode edges
Where it’s still weak
- Telephoto zoom quality stays average
- AI scene detection sometimes oversaturates colors
- Night mode can slightly soften details
If you take photos casually, you’ll notice a nice bump. If you’re expecting flagship-level performance? Calm your expectations.
Gaming and Thermal Performance
For gamers wondering whether to update:
Advantages
- Reduced frame drops over long sessions
- Better CPU/GPU management
- Less throttling under 60-minute gameplay tests
Disadvantages
- Slight heating during 30–60 FPS games like Genshin Impact, CODM
- Occasional touch-response delay when screen recording is enabled
Not a deal-breaker, but hardcore gamers won’t call it a perfect upgrade either.
Privacy, Security & Stability
This part usually gets ignored in flashy update reviews, but it matters deeply in the long run.
New Privacy Upgrades
- App-level network permission control
- Real-time mic/camera access indicator overhaul
- Isolated app space for sensitive apps
The security patch cycle also seems tighter and more consistent than before.
The stability question
Every major OS update comes with bugs — but Nothing OS 4.0 is surprisingly stable for a first rollout.
The few issues reported are:
- Adaptive brightness misbehaving occasionally
- Notification sound randomly changing on reboot (rare but exists)
- Some widgets don’t scale properly on older Nothing phones
So if you are extremely bug-sensitive, maybe wait for the minor 4.0.1 patch — but the current build is stable enough for most daily drivers.https://nothing.community/t/nothing-os

How to download Nothing OS 4.0 beta
Pre-check: Are you eligible & ready?
- Check if your phone model is supported. According to the official community post: the Open Beta is available for:
- Nothing Phone 3 (and series)
- Nothing Phone 2
- Nothing Phone 2a / 2a Plus.
If you have a later model (e.g., Phone 3a / 3a Pro) the update might arrive later.
- Make sure your current software is updated to the stable build required before joining the beta. For example: for Phone 3: version “Metroid-V3.5-250911-2112”.
- Backup your data. Because: the manufacturers explicitly warn that installing the beta might lead to factory resets, and you may lose data.
- Be aware of risks: betas are inherently less stable. If you rely on your phone for work/school and can’t afford downtime, you might choose to wait for the stable release.
🔧 Step-by-Step Installation
Here’s how to install the beta:
- Download the “Beta Updates Hub” app (.apk) from the official site of Nothing / the community thread.
- On your phone, go to Settings → System → Nothing Beta Hub.
- In the Beta Hub, tap “Join Beta” (or similar) to enrol. Once enrolled, tap “Go to Update” (or check for updates manually: Settings → System → System updates).
- Download the update when it becomes available. Make sure your phone is plugged in or has sufficient battery.
- After downloading, install the update. Your phone will reboot and apply the new OS version.
- Once installation completes, explore the new features, UI changes, etc. But also check for any bugs, app-incompatibilities.
🔙 Rolling Back / Exiting Beta
If you decide the beta isn’t stable for you and want to go back:
- Download the rollback package from the official site.
- In Settings → System → Nothing Beta Hub → “Import file” → select the rollback package.
- Important: Rolling back will factory-reset your device (erasing data). Always backup.
Final Verdict
Nothing did something many Android brands fail to do: instead of adding bloat, they added refinement. Nothing OS 4.0 is not perfect, but it brings improvements that matter where users actually feel them — fluidity, battery, design identity, and everyday consistency.
If we have to summarize in one sentence:
👉 Nothing OS 4.0 is absolutely worth upgrading to — not because it’s revolutionary, but because it meaningfully improves the user experience without gimmicks.
