Detailed Comparison

Display

Nothing Phone (3a)

The 6.7-inch AMOLED with 120Hz refresh rate delivers vivid colors and smooth performance that belies the budget price.

The 6.7-inch AMOLED panel with 120Hz is bright, vivid, and responsive — you'd never guess this is a $349 phone from the display alone
Peak brightness is adequate for outdoor use but falls short of flagship-level phones — direct sunlight readability is good but not exceptional
Colors are accurate in the default profile with excellent contrast — HDR content looks surprisingly good on this panel

Samsung Galaxy S25 Ultra

Virtually every reviewer calls the S25 Ultra display the best on a smartphone, thanks to the Gorilla Armor 2 anti-reflective coating that practically eliminates glare in sunlight, the 2,600-nit peak brightness, and the sharp 1440p LTPO panel. A few reviewers note PWM dimming only reaches 480 Hz and peak auto-brightness doesn't always sustain.

The anti-reflective coating makes it one of the easiest phones to use in direct sunlight and held up well to scratches over a week of abuse.
The Gorilla Armor 2 panel strikes an almost perfect balance between glossy and matte, with 2,600-nit peak brightness that dazzles in any environment.

What Reviewers Agree On

The 6.9-inch QHD+ LTPO AMOLED with Gorilla Armor 2 anti-reflective coating is the best smartphone display you can buy right now.
The Snapdragon 8 Elite for Galaxy and larger vapor chamber deliver benchmark-leading, consistently smooth performance with minimal thermal throttling.
Battery life on the 5,000 mAh cell easily lasts a full day, with most reviewers ending on 30-40% remaining.
The new rounded corners and flatter titanium frame make the phone noticeably more comfortable to hold than the S24 Ultra.
The new 50MP ultrawide is a real, visible upgrade — sharper detail, better low-light performance and autofocus for macro.
Gorilla Armor 2 and the titanium frame make this one of the most durable flagship phones available.
Seven years of OS and security updates match the best in the industry and help justify the long-term investment.

Deal Breakers

The S Pen lost Bluetooth functionality this year, so remote shutter and Air Actions gestures are gone — a sore point for long-time Samsung owners on Reddit who see it as another feature cut from the 'everything phone.'
At $1,299 the hardware year-over-year gains are minimal, and Reddit sentiment on r/gadgets and r/Android echoes what reviewers say: the Ultra no longer feels special enough to justify the premium.
Qi2 wireless charging only works through a separate magnetic case — the phone itself has no built-in magnets.
The main 200MP and 5x telephoto cameras are physically unchanged from the S24 Ultra, so image quality gains are marginal.
Galaxy AI features are guaranteed free only through the end of 2025, with Samsung hinting at future paid tiers — and Reddit users on r/gadgets are already skeptical the features justify being front-and-center at all.
Shutter lag on the main camera still trails iPhone and Pixel — flagged by 9to5Google in long-term testing and cited by r/apple commenters as a reason they haven't switched.

Camera

Nothing Phone (3a)

The standout feature — a triple camera system with 50MP telephoto at $349 that no budget competitor can match.

A 50MP telephoto with 2x optical zoom at $349 is unprecedented — no budget phone offers a dedicated zoom lens, and the results are genuinely impressive
The 50MP main sensor produces detailed, well-exposed photos with natural colors that compete with phones costing twice as much
Low-light photography is adequate but expectedly falls behind Pixel's computational processing — noise is more visible in dim conditions
Video recording at 4K30 is solid with decent stabilization, though the lack of 4K60 is a limitation some users will notice

Samsung Galaxy S25 Ultra

The only new hardware is a 50MP ultrawide with an f/1.9 aperture and autofocus — the 200MP main, 10MP 3x and 50MP 5x telephoto lenses all carry over from the S24 Ultra. Reviewers agree the ultrawide is a genuine improvement and low-light video processing is noticeably cleaner, but colors still skew saturated and shutter lag persists — a complaint echoed on Reddit by would-be switchers. Samsung's imaging is now slightly behind the Vivo X200 Pro and Xiaomi 15 Ultra but remains top-tier.

The new 50MP ultrawide delivers more fine detail than the S24 Ultra's sensor, and the wider f/1.9 aperture helps keep noise low.
Some low-light ultrawide shots are sharper than both the Google Pixel 9 Pro and iPhone 16 Pro Max, but the rest of the cameras feel static.
Samsung's penchant for slightly overboard sharpening is still visible, though the new ultrawide beats what the Pixel 9 Pro can do.
Photos straight from the camera are a little too natural-looking, and most shots need editing to look their best.
The 3x optical zoom uses a small, outdated sensor and is now a weak point of the camera setup.
All cameras stay the same as on the S24 Ultra except the ultrawide, and Samsung is relying on the new ISP to improve quality.
The S25 Ultra takes better zoom and ultrawide photos than last year with cleaner skin tones, and shutter lag is finally put to bed.
Samsung has aimed for consistency, and after six months the stills are vibrant yet muted — pictures up to 15x zoom remain tack-sharp.
The shutter activation is slow and not as instant as competing phones — a persistent Galaxy flaw Samsung should address.
Side-by-side low-light video clips versus the S24 Ultra show clearly more fine detail from the S25 Ultra.
iPhone-curious switchers on r/apple still call out shutter lag as the thing holding them back: 'I just want to open the camera and snap a picture right away. I don't want to have a motion blurred photo.'

Performance

Nothing Phone (3a)

The Snapdragon 7s Gen 3 with 8GB RAM handles everyday tasks smoothly, though it shows its limits with demanding gaming.

Day-to-day performance is smooth and responsive — apps open quickly, multitasking is adequate, and Nothing OS animations are fluid
Casual gaming runs well, but demanding titles like Genshin Impact need reduced settings for a smooth experience
8GB RAM ensures good app retention for moderate multitasking, though heavy users may notice occasional reloads

Samsung Galaxy S25 Ultra

The Snapdragon 8 Elite for Galaxy delivers a meaningful generational jump in both CPU and GPU, rivaling Apple's A18 Pro and outscoring the iPhone 16 Pro Max in multi-core. The 40 percent larger vapor chamber keeps the phone cool even under sustained gaming loads. The r/apple thread citing a 36% GPU lead over the iPhone 16 Pro Max generated heated discussion, with most commenters conceding the Snapdragon chip is genuinely fast even if they still wouldn't switch.

The phone benchmarks crazy high, rivaling Apple's A18 Pro — a little lower in single core but higher in multi-core.
Samsung's 40 percent larger vapor chamber keeps the phone from warming up in normal use and benchmarks are up 30-40 percent depending on the task.
Playing Genshin Impact at max settings for nearly an hour produced no stutters and no hot spots — a noticeable improvement over the S24 series.
Multi-core Geekbench hits 9,793 versus the iPhone 16 Pro Max at 8,772 — the S25 Ultra pulls ahead thanks to extra cores and 12GB of RAM.
The Snapdragon 8 Elite is the most welcome generational upgrade this year, with a boosted 'for Galaxy' variant delivering more CPU headroom than the standard chip.
Under heavy loads the S25 Ultra becomes a bit power-hungry, which can cause faster-than-expected battery drain when multitasking or running demanding apps.
Everyday tasks run smoothly and there was no meaningful performance difference versus the OnePlus 13 running the same chip.
Apple users on r/apple concede Apple has fallen behind on GPU performance, saying 'competition is good' after the S25 Ultra posted a roughly 36% GPU lead in benchmarks.
