Nothing Phone (3a) Pro Review: The Budget AI Phone That's Changing The Mid-Range Game

The Budget AI Phone That Stands Out From The Crowd

In a sea of similar-looking smartphones, the Nothing Phone (3a) Pro immediately demands your attention. With its transparent design, AI-powered features, and a periscope zoom camera that’s rare at this price point, this £459 ($459) device is challenging what we expect from mid-range phones in August 2025.

After spending a month testing this device extensively, I can confidently say that Nothing has created something special—an Android phone that delivers unique hardware design combined with practical AI features that actually enhance daily use rather than just existing as marketing gimmicks.

But is the Nothing Phone (3a) Pro the right device for you? Let’s dive deep into what makes this phone tick, where it excels, and where compromises have been made to achieve that attractive price point.

Design & Build: Transparent and Polarizing

The moment you take the Nothing Phone (3a) Pro out of its minimalist packaging, you’re greeted by that signature transparent back panel that has become Nothing’s calling card. Unlike many “unique” phone designs that quickly become tiresome, there’s something enduringly intriguing about seeing the internal components of your device.

The most noticeable design element is the massive circular camera housing for the 3x periscope lens. It’s bold and distinctive, making a statement about the phone’s photographic capabilities. As one Reddit user (u/DerGigantAusDemAll) noted: “The camera bump is certainly a matter of taste. I personally really like it, as it gives the device that ‘Pro’ look.”

The Glyph Interface—a series of LED light strips on the back—continues to be Nothing’s most divisive feature. It lights up for notifications, timers, and incoming calls in customizable patterns. Some users find it genuinely useful; others consider it a gimmick. After a month with the device, I fall somewhere in the middle—it’s not essential, but it does add a dash of personality that most phones lack.

Build quality is a mix of premium and budget elements. The front and back are glass (with Panda Glass protection on the rear), while the frame uses a plastic-aluminum composite that Nothing insists is “100% aluminum” but definitely has a plastic-like feel in hand. The IP64 rating provides protection against dust and splashes but falls short of the full waterproofing found on flagship devices.

Available in Black or Gray (less vibrant than the regular 3a’s Blue/White options), the Gray version seems to be the consensus favorite among users for showcasing the transparent design more effectively.

Display: Bright & Smooth

The Nothing Phone (3a) Pro sports a 6.77” AMOLED panel that impresses in several ways:

• 120Hz refresh rate delivers silky-smooth scrolling
• 3000 nits peak brightness makes it exceptionally readable outdoors
• PWM dimming at 2160Hz reduces eye strain in low-light conditions
• Flat display edges make applying screen protectors much easier

In direct comparison with competitors, the display outshines the iPhone 16e (which maxes out at 1028 nits) in brightness but doesn’t quite match the color accuracy of the Pixel 8a. For most users, however, these differences will be negligible in daily use.

As one Reddit reviewer commented: “Both panels have excellent specs in terms of brightness, refresh rate, and resolution. According to the spec sheet, the Pixel 9a gets brighter in day-to-day use. However, in practice, I didn’t notice a significant difference, even in sunlight.”

Performance: Mid-Range Done Right

Powered by the Snapdragon 7s Gen 3 chipset paired with a generous 12GB of RAM, the Nothing Phone (3a) Pro delivers a smooth experience for everyday tasks but shows limitations when pushed to its limits.

Everyday Performance

For browsing, social media, productivity apps, and multitasking, the phone feels remarkably fluid. Nothing’s optimization work shines here—the interface animations are buttery smooth, and app launches are impressively quick. The 12GB RAM allocation is particularly beneficial for multitasking, allowing more apps to remain active in memory.

One Reddit user who compared it directly to the Pixel 9a noted: “Not only does the Phone 3a Pro have more RAM, but it’s also less restrictive with background apps. Pixel devices tend to close background apps quickly, which really bothers me… The Phone 3a Pro keeps apps running for ages—I often open apps I last used the day before and they don’t need to reload.”

Gaming Performance

This is where the mid-range nature of the device becomes apparent. The Snapdragon 7s Gen 3 handles casual games without breaking a sweat, but more demanding titles like Genshin Impact require medium settings to maintain playable framerates. Extended gaming sessions also reveal the lack of a dedicated cooling system, with noticeable warmth building up over time.

Benchmark scores tell part of the story:

• Geekbench 6: 1,179 (single-core) / 3,308 (multi-core)
• These scores place it firmly in the mid-range territory, roughly 25% behind last generation’s flagship processors

Cameras: The Best Zoom Under $500

The camera system on the Nothing Phone (3a) Pro is where this device truly distinguishes itself from other mid-range offerings:

Main Camera: 50MP Samsung GN2

• Excellent dynamic range in good lighting
• Natural color reproduction with minimal over-processing
• Capable night performance, though not class-leading

3x Periscope Telephoto: 50MP

• A genuine differentiator at this price point
• Delivers surprisingly good image quality up to 6x zoom
• Allows for creative framing options typically reserved for flagships

Ultrawide Camera: 8MP

• The obvious weak point in the system
• Acceptable in good lighting but struggles in challenging conditions
• Limited resolution impacts detail capture

Selfie Camera: 50MP

• Impressively sharp results
• Some users report over-processing of skin tones

The inclusion of a true periscope telephoto lens at this price point can’t be overstated—it’s a feature typically reserved for phones costing $200-300 more. The 3x optical zoom produces sharply detailed images that digital zoom simply cannot match.

A Reddit user who’s been using the phone for a month shared: “I mostly use the 3x more than main camera. I like it more… One thing is if you want to shoot videos in telephoto lens you need to switch the lens to 3x before starting the video recording. Otherwise, it would just zoom in the main camera.”

While Google’s computational photography still gives the Pixel 8a an edge in overall image consistency and low-light performance, the versatility offered by Nothing’s camera system makes it the more compelling option for many photography enthusiasts.

AI Features: Useful but Unfinished

Nothing’s approach to AI feels refreshingly practical, focused on organizing information rather than gimmicky editing tools. The centerpiece is “Essential Space”—a dedicated system for collecting and organizing screenshots, voice notes, and text.

Essential Space: The Killer Feature?

Essential Space acts as an AI-powered personal assistant that automatically organizes your captured content:

• Single-press Essential Key: Takes a screenshot
• Long-press: Records a voice memo and transcribes to text
• AI Organization: Automatically groups related content into collections (receipts, travel plans, etc.)
• Data Extraction: Identifies dates and actionable information, creating calendar events or reminders

This feature genuinely improves productivity by reducing the time spent searching through screenshots and notes. However, it’s not without issues. Multiple users report buggy transcriptions where the AI occasionally misinterprets English as other languages.

Another limitation is that you cannot remap the Essential Key to other functions, which has frustrated some users who would prefer more customization options. As one Redditor pointed out: “Not much of a use for me. I am thinking of remapping the key. And I am assuming that most of the features are only free for 1 year. That is a bad move on their part when you have a dedicated hardware switch but you can only use it by paying for it after some period.”

Other AI Features

Beyond Essential Space, the Nothing Phone (3a) Pro includes:

• Google’s Circle to Search for visual searches
• Gemini integration for AI assistance
• Basic AI photo enhancement (though nothing as advanced as Google’s Magic Eraser)

Nothing has promised more AI features through software updates, including improved auto-organization capabilities, but for now, the implementation feels somewhat unfinished but promising.

Battery & Charging: All-Day Endurance

The 5000mAh battery in the Nothing Phone (3a) Pro delivers impressive longevity:

• 12h 45m screen-on time in standardized video playback tests
• Comfortably lasts a full day of moderate to heavy use
• Efficiency optimization helps preserve battery life even with 120Hz enabled

Charging capabilities are solid but not extraordinary:

• 50W wired charging delivers approximately 62% charge in 30 minutes
• No wireless charging (a notable omission compared to some competitors)
• No charger included in the box (an increasingly common trend)

One user reported: “Battery lasts for one whole day when you limit the battery by 20%-80% (this is what I found for my use) and more than one day if you charge to 100%.”

Software Experience: Streamlined and Smooth

Nothing OS 3.1 (based on Android 15) is one of the most appealing aspects of the Phone (3a) Pro. The interface is clean, minimalist, and refreshingly free of bloatware—a stark contrast to the heavy skins offered by many competitors.

The software includes thoughtful additions that enhance usability without feeling overwhelming:

• Three-finger screenshot gesture
• Native support for AirPods
• Useful custom widgets (pedometer, ChatGPT)
• Customizable Glyph patterns

Nothing promises 3 OS updates and 6 years of security patches—not quite matching Google’s 7-year commitment for Pixel devices, but still offering reasonable longevity.

There are occasional bugs reported by users, though nothing that significantly impacts daily use. As one user mentioned: “There are some bugs. Not the type that makes your phone unusable. But some minor bugs are there. And I think they might resolve it in the updates. Major bugs they do address in the prioritised updates.”

Connectivity & Availability: The US Challenge

The Nothing Phone (3a) Pro offers standard connectivity options:

• 5G support (sub-6GHz only, no mmWave)
• Wi-Fi 6
• Bluetooth 5.3
• NFC for contactless payments

However, availability and carrier compatibility remain problematic for US buyers. The phone offers limited US carrier support (working well with T-Mobile but problematic with AT&T and Verizon), and purchases require joining the Nothing Beta Program rather than standard retail channels.

This regional limitation is perhaps the biggest obstacle to widespread adoption in the American market, despite the device’s compelling features.

Value Proposition: A Unique Mid-Range Option

Priced at $459/£459, the Nothing Phone (3a) Pro occupies an interesting position in the market:

What you’re paying for:

• Distinctive transparent design with Glyph interface
• True 3x periscope telephoto camera (rare at this price)
• Clean, optimized software experience
• AI-powered organization tools
• 12GB RAM (generous for the price segment)

What you’re compromising on:

• Gaming performance compared to gaming-focused phones
• Ultrawide camera quality
• No wireless charging
• Limited US availability and carrier support
• Some AI features still feel like works in progress

The Reddit Verdict

To incorporate real user perspectives beyond my testing, I examined numerous Reddit threads about the Nothing Phone (3a) Pro. One particularly insightful comparison came from u/DerGigantAusDemAll who compared it directly to the Pixel 9a:

“The Phone 3a Pro feels different and magical in many ways. The Glyph back draws lots of attention—you constantly get asked about it. Every incoming message brings a little spark of joy. I also absolutely love the design. I really connect with Nothing’s whole philosophy… It’s a device that delivers the same reliability you’d expect from a Pixel in almost every category—while adding a bit of magic to my everyday life.”

This sentiment was echoed across multiple threads—users appreciate the combination of solid fundamentals with distinctive design and features that make the device feel special in a way that most mid-range phones don’t.
