Nothing Phone 3a Pro review: funky mid-ranger with real zoom camera | Smartphones

London-based Nothing has brought one of the last things setting top-level phones apart from cheaper mid-range models down to a more affordable price: high-quality camera zoom.
Cameras have long been the battleground of the most expensive phones, each vying for better quality, longer reach and multiple lenses. While much of this costly progress has trickled down to cheaper models, optical zoom cameras are few and far between below the £600 mark.
The £449 (€459/$459/A$849) Nothing 3a Pro sets itself apart with the company’s trademark transparent, light-up design and a 50-megapixel 3x telephoto camera on the back that rivals phones costing twice as much.
It builds on the excellent Phone 2a with a similar set of “glyph” LED strips on the back that light up in complex patterns for notifications, calls, timers, charging, the volume and other fun things.
The transparent glass back reveals an interesting design beneath, but the gigantic camera cluster is the standout element. It is huge and protrudes far enough for it to act like a grip for your finger on the back of the phone. The back and front of the 3a Pro are glass, while the sides are a high-quality plastic.
The screen is a large and fast OLED, which looks really good and has fast optical fingerprint scanner under it towards the bottom.

The 3a Pro has Qualcomm’s mid-range Snapdragon 7s Gen 3 chip, which can’t rival the top chips for raw power but is fast enough to make the phone feel snappy and responsive. It can handle most games fine without getting hot and is about 25% faster than the Phone 2a.
The battery life is great, lasting about three days between charges with general use, including more than seven hours spent actively using the screen. Gaming and using the camera dents the battery, but even so most should only need to charge it every other day.
NothingOS
The 3a Pro runs Nothing’s version of Android 15, which offers a relatively clutter-free, fast and unique experience filled with nice design touches based around dot-matrix art. There are plenty of customisation options to tailor the look and feel of the phone, including monochrome and distraction-free themes, but generally it is just a bit more fun than most version of Android.
It has a few of Google’s AI tools, including Gemini, and various image editing tools in Google Photos. But the big new addition is Nothing’s Essential Space app, which acts like an AI-powered notebook capable of collecting and analysing various screenshots, text and voice notes.
A dedicated button on the side of the phone captures what’s on screen, while pressing and holding records a quick voice note to go with it. The app analyses the content to create summaries, transcriptions and possible actions, such as reminders or to-do lists. Opening the app shows the various things you’ve captured sorted into collections, such as a cross between Pinterest and a note-taking app such as Evernote.
The app is a little basic at the moment and requires a connection to Nothing’s servers to work, but the idea is sound and it currently works well as a way of keeping screenshots and other data out of your gallery. The AI summaries, like all AI tools, are a bit hit and miss, and your various captures are stuck on your phone, but it has far more potential than a lot of gimmicky AI features currently being touted by various parties.
Unfortunately, you can’t customise the side button to do something else, so if you don’t like Essential Space it is rendered useless, unlike rivals such as Apple’s action button. I also pressed it a lot, mistaking it for the power button, taking a fair number of accidental screenshots in the process.
Nothing will support the 3a Pro with three years of Android updates and a total of six years of security updates. That is a year or so behind the best in the business but a lot longer than many rivals, which is good to see.
Camera
The 3a Pro has three cameras on the back: an 8-megapixel ultrawide, a 50MP main and a 50MP 3x telephoto, the later of which is the standout feature for this price range of phone.
The ultrawide camera is reasonable, if a little soft on detail. The main camera is pretty good all round with solid colour and dynamic range, making a decent job of most situations. The 3x zoom camera is arguably the best of the lot, producing nicely detailed images with reasonable reach. All three cameras suffer from a bit of overprocessing, which you can see when you zoom in on photos. The main and telephoto cameras offer an in-sensor zoom to 2x and 6x respectively, but they are not great showing obvious artefacts, while zooming beyond 10x the images start to look more like oil paintings than photos.
Overall, the camera on the 3a Pro is one of the best for a mid-range phone and offers a real zoom, which is rare at this price. It won’t trouble the top Android or iPhones, however.
Sustainability
Nothing says the battery maintains at least 90% of its original capacity for at least 1,200 full charge cycles. The Phone 2a is generally repairable in the UK. Screen replacements cost £89 or batteries cost £29 plus about £35 labour and shipping by Nothing.
The device is made of recycled aluminium, copper, plastic, steel, tin and other materials. It has a carbon footprint of 51.3kg CO2 equivalent. The company publishes sustainability reports.
Price
The Nothing Phone 3a Pro costs £449 (€459/$459/A$849).
For comparison, the Phone 3a costs £329, the Google Pixel 8a costs £499, the Samsung Galaxy A56 costs £499 and the iPhone 16e costs £599.
Verdict
Nothing hits the right notes with the Phone 3a Pro to make it one of the best mid-range phones you can buy.
Very few rivals have a real zoom camera at this price, let alone one as good as on the back of the 3a Pro. It has a big, crisp and smooth display, solid mid-range performance and very long battery life. A standout design adds interest to the otherwise dull phone market, while good software with up to six years of support means it will go the distance.
Nothing’s AI-powered screenshot and note-taking app shows potential, even if it is a bit basic at the moment. But giving it a dedicated button that can’t be used for anything else feels like a miss. I would rather choose which app or function to bind to the button.
The mid-range smartphone market is rapidly becoming packed with very good options, but Nothing manages to stand out and is worth considering when your old phone gives up the ghost.
Pros: good camera with 3x optical zoom, interesting design, great software with six years of support, good screen, solid performance, long battery life, good fingerprint scanner, splash resistant.
Cons: AI features need work, extra button can’t be customised, only three years of Android version updates, enormous camera cluster protrudes from the back.

Pentagon research official wants to have AI on every desktop in 6 to 9 months

The Pentagon is angling to introduce artificial intelligence across its workforce within nine months following the reorganization of its key AI office.
Emil Michael, under secretary of defense for research and engineering at the Department of Defense, talked about the agency’s plans for introducing AI to its operations as it continues its modernization journey.
“We want to have an AI capability on every desktop — 3 million desktops — in six or nine months,” Michael said during a Politico event on Tuesday. “We want to have it focus on applications for corporate use cases like efficiency, like you would use in your own company … for intelligence and for warfighting.”
This announcement follows the recent shakeups and restructuring of the Pentagon’s main artificial intelligence office. A senior defense official said the Chief Digital and Artificial Intelligence Office will serve as a new addition to the department’s research portfolio.
Michael also said he is “excited” about the restructured CDAO, adding that its new role will pivot to a focus on research that is similar to the Defense Advanced Research Projects Agency and Missile Defense Agency. This change is intended to enhance research and engineering priorities that will help advance AI for use by the armed forces and not take agency focus away from AI deployment and innovation.
“To add AI to that portfolio means it gets a lot of muscle to it,” he said. “So I’m spending at least a third of my time –– maybe half –– rethinking how the AI deployment strategy is going to be at DOD.”
Applications coming out of the CDAO and related agencies will then be tailored to corporate workloads, such as efficiency-related work, according to Michael, along with intelligence and warfighting needs.
The Pentagon first stood up the CDAO and brought on its first chief digital and artificial intelligence officer in 2022 to advance the agency’s AI efforts.
The restructuring of the CDAO this year garnered attention due to its pivotal role in investigating the defense applications of emerging technologies and defense acquisition activities. Job cuts within the office added another layer of concern, with reports estimating a 60% reduction in the CDAO workforce.

Pentagon CTO wants AI on every desktop in 6 to 9 months

The Pentagon aims to get AI tools to its entire workforce next year, the department’s chief technical officer said one month after being given control of its main AI office.
“We want to have an AI capability on every desktop — 3 million desktops — in six or nine months,” Emil Michael, defense undersecretary for research and engineering, said at a Politico event on Tuesday. “We want to have it focus on applications for corporate use cases like efficiency, like you would use in your own company…for intelligence and for warfighting.”
Four weeks ago, the Chief Digital and Artificial Intelligence Office was demoted from reporting to Deputy Defense Secretary Stephen Feinberg to Michael, a subordinate.
Michael said CDAO will become a research body like the Defense Advanced Research Projects Agency and Missile Defense Agency. He said the change is meant to boost research and engineering into AI for the military, but not reduce its efforts to deploy AI and make innovations.
“To add AI to that portfolio means it gets a lot of muscle to it,” he said. “So I’m spending at least a third of my time—maybe half—rethinking how the AI-deployment strategy is going to be at DOD.”
He said applications would emerge from the CDAO and related agencies that will be tailored to corporate workloads.
The Pentagon created the CDAO in 2022 to advance the agency’s AI efforts and look into defense applications for emerging technologies. The office’s restructuring earlier this year garnered attention. Job cuts within the office added another layer of concern, with reports estimating a 60% reduction in the CDAO workforce.

Panelists Will Question Who Controls AI | ACS CC News
Artificial intelligence (AI) has become one of the fastest-growing technologies in the world today. In many industries, individuals and organizations are racing to better understand AI and incorporate it into their work. Surgery is no exception, and that is why Clinical Congress 2025 has made AI one of the six themes of its Opening Day Thematic Sessions.
The first full day of the conference, Sunday, October 5, will include two back-to-back Panel Sessions on AI. The first session, “Using ChatGPT and AI for Beginners” (PS104), offers a foundation for surgeons not yet well versed in AI. The second, “AI: Who Is In Control?” (PS 110), will offer insights into the potential upsides and drawbacks of AI use, as well as its limitations and possible future applications, so that surgeons can involve this technology in their clinical care safely and effectively.
“AI: Who Is In Control?” will be moderated by Anna N. Miller, MD, FACS, an orthopaedic surgeon at Dartmouth Hitchcock Medical Center in Lebanon, New Hampshire, and Gabriel Brat, MD, MPH, MSc, FACS, a trauma and acute care surgeon at Beth Israel Deaconess Medical Center and an assistant professor at Harvard Medical School, both in Boston, Massachusetts.
In an interview, Dr. Brat shared his view that the use of AI is not likely to replace surgeons or decrease the need for surgical skills or decision-making. “It’s not an algorithm that’s going to be throwing the stitch. It’s still the surgeon.”
Nonetheless, he said that the starting presumption of the session is that AI is likely to be highly transformative to the profession over time.
“Once it has significant uptake, it’ll really change elements of how we think about surgery,” he said, including creating meaningful opportunities for improvements.
The key question of the session, therefore, is not whether to engage with AI, but to do so in ways that ensure the best outcomes: “We as surgeons need to have a role in defining how to do so safely and effectively. Otherwise, people will start to use these tools, and we will be swept along with a movement as opposed to controlling it.”
To that end, Dr. Brat explained that the session will offer “a really strong translational focus by people who have been in the trenches working with these technologies.” He and Dr. Miller have specifically chosen an “all-star panel” designed to represent academia, healthcare associations, and industry.
The panelists include Rachael A. Callcut, MD, MSPH, FACS, who is the division chief of trauma, acute care surgery and surgical critical care as well as associate dean of data science and innovation at the University of California-Davis Health in Sacramento, California. She will share the perspective on AI from academic surgery.
Genevieve Melton-Meaux, MD, PhD, FACS, FACMI, the inaugural ACS Chief Health Informatics Officer, will present on AI usage in healthcare associations. She also is a colorectal surgeon and the senior associate dean for health informatics and data science at the University of Minnesota and chief health informatics and AI officer for Fairview Health Services, both in Minneapolis.
Finally, Khan Siddiqui, MD, a radiologist and serial entrepreneur who is the cofounder, chairman, and CEO of a company called HOPPR AI, will present the view from industry. HOPPR AI is a for-profit company focused on building AI apps for medical imaging. As a radiologist, Dr. Siddiqui represents a medical specialty that is thought to likely undergo sweeping change as AI is incorporated into image-reading and diagnosis. His comments will focus on professional insights relevant to surgeons.
Their presentations will provide insights on general usage of AI at present, as well as predictions on what the landscape for AI in healthcare will look like in approximately 5 years. The session will include advice on what approaches to AI may be most effective for surgeons interested in ensuring positive outcomes and avoiding negative ones.
Additional information on AI usage pervades Clinical Congress 2025. In addition to various sessions that will comment on AI throughout the 4 days of the conference, various researchers will present studies that involve AI in their methods, starting presumptions, and/or potential applications to practice.
