Camera

OnePlus 15

The Hasselblad-tuned triple camera system delivers natural colors and excellent portraits, with a 50MP main, 50MP ultrawide, and 50MP 3x periscope telephoto.

Hasselblad color science produces warm, natural tones that look true to life — portraits are particularly impressive with excellent skin tone rendering and bokeh
The 3x periscope telephoto delivers sharp, detailed shots and the 50MP sensor means cropping to 6x still produces usable results
In challenging mixed-lighting conditions, HDR processing can occasionally produce artifacts and inconsistent exposure between the three lenses
Video recording at 4K60 is excellent with effective stabilization, though Dolby Vision HDR video still trails iPhone in dynamic range

Samsung Galaxy S25

The 50MP main + 12MP ultrawide + 10MP 3x telephoto setup delivers reliable results. AI photo editing tools add genuine value, though hardware improvements over S24 are minimal.

Camera experience is just okay — display is excellent, performance is on point, but cameras need more attention
Galaxy AI photo editing features like Generative Edit genuinely improve the experience
Hardware is largely unchanged from S24 — feels like Samsung is coasting on software improvements alone
