A comparison of sample photos pits the OnePlus 15 against the Galaxy S25 Ultra.

OnePlus has replaced its signature circular camera design with a rectangular module on the rear panel this year. While it may appear less unique, the focus remains on image performance.

Interestingly, the 15 series marks the end of OnePlus' collaboration with Hasselblad. However, this change might yield positive results.

How does the OnePlus 15 stack up against the Galaxy S25 Ultra, a popular choice among Android enthusiasts?

While the OnePlus 15's 50MP primary camera has a slightly smaller sensor than the Galaxy, and lacks a second telephoto lens found on the Samsung, its 3.5x telephoto camera features a larger sensor than the Galaxy's 3x lens. The ultrawide lenses are also very similar.

Will these differences impact the image quality of the OnePlus, or will its processing capabilities compensate?
