A recently published comparison test shows that although the recently presented Vivo X300 has a smaller sensor than the Galaxy S25 Ultra, it apparently delivers more convincing image quality.
Highlights
- Vivo X300 uses a 200 megapixel sensor in 1/1.4 inch format – compared to the 1/1.3 inch sensor in the Galaxy S25 Ultra.
- In the comparison test, the Vivo presented itself with more vivid colors, more details and less image noise – despite the “smaller” sensor size.
- The optimization of the software algorithms and the cooperation with Zeiss for the optics appear to be the decisive factors.
- The Vivo X300 is both more compact (6.3-inch display) and cheaper than the 6.9-inch Ultra model from Samsung – an interesting fact in the high-end segment.
Vivo relies on 200 MP sensor
In terms of camera quality, the Samsung Galaxy S25 Ultra (€ 1,569.00 *) is undoubtedly at the top of the smartphone market. However, a recent comparison test shows that the flagship is apparently beaten by the Vivo X300. The X user PhoneArt has published corresponding comparison images on X. And this despite a weaker sensor on the Vivo.

The camera of the Vivo X300 uses a 200 MP ISOCELL HPB sensor with a format of 1/1.4 inches and an aperture of f/1.7. In direct contrast, the Galaxy S25 Ultra has a sensor size of 1/1.3 inches with f/1.7 (for the wide angle). So in terms of sensor size, Samsung has the advantage here. However, Vivo combines this sensor with Zeiss optics and revised software algorithms.

This probably means that the Vivo smartphone’s images offer better color intensity and more recognizable depth of detail. The images also benefit from less image noise. The cooperation with Zeiss is likely to be a key factor here. Among other things, it improves light control and image clarity across the entire surface.
Conclusion
The camera of the Vivo X300 impressively demonstrates that it is not only the sensor size that counts – the coordination of sensor, optics and software is also important. In a direct comparison with the Galaxy S25 Ultra, the more compact and cheaper model came out on top in at least one test procedure. This is an exciting signal for technology enthusiasts, photo specialists and mobile creatives: a top camera does not necessarily have to be the largest or most expensive model. If you value strong camera performance and prefer a more compact device, the Vivo X300 should be on your radar.
