Nothing OS delivers the most charming and distinctive software experience in the budget category, with minimal bloat
The 5,000mAh battery provides excellent two-day endurance with light use and easy all-day life with heavy use

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

The 6.9-inch Dynamic AMOLED 2X display with 2600 nit peak brightness and anti-reflective coating is universally praised as the best smartphone display available.

2600 nit peak brightness with anti-reflective coating makes it the most sunlight-readable phone
120Hz LTPO refresh rate is butter smooth with excellent touch response

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 quad camera system features an improved 200MP main sensor, 50MP ultrawide, 10MP 3x telephoto, and 50MP 5x periscope. Galaxy AI enhances post-processing significantly.

200MP main sensor produces incredibly detailed shots with improved noise handling
Galaxy AI photo editing (Generative Edit, Best Face) is genuinely useful and well-implemented
Video recording improvements with LOG support appeal to content creators
Night mode still trails iPhone 16 Pro in very low light scenarios

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

Snapdragon 8 Elite delivers the fastest Android performance available with excellent efficiency. 12GB RAM handles multitasking and AI workloads effortlessly.

Snapdragon 8 Elite is a beast — fastest Android chip with significant efficiency gains
On-device AI processing is noticeably faster than cloud-based alternatives
Thermals are well-managed with the larger vapor chamber — no throttling in sustained use
