OnePlus 13

A major step up for OnePlus cameras, though still not quite matching Apple and Samsung's best.

The Hasselblad color science produces natural, film-like images that many will prefer over Samsung's punchy processing.
Low-light performance has improved dramatically but still falls slightly behind the iPhone 16 Pro in challenging conditions.

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
