Do more megapixels mean a better phone camera?
Not by themselves. Megapixels only count how many pixels the photo has. Image quality depends more on how much light the sensor collects (its size), the lens, and the phone's processing — "computational photography" that merges many frames into one shot. Lab scores like DxOMark help, but their weighting is secret.
Megapixels are how many tiles a mosaic has. More tiles only helps if there's enough light to see each one clearly — and a bigger window (sensor) lets in more light than extra tiles do.
Megapixels vs sensor size
A megapixel is a million pixels. Packing more of them onto a tiny phone sensor makes each one smaller, so each catches less light, which shows up as noise in dim scenes. A larger sensor collects more light overall. Photography references note that the megapixel race in phone cameras was driven more by marketing than by image quality.
Processing does the heavy lifting
Computational photography uses software instead of optics to improve a shot: combining a burst of frames to reduce noise and widen dynamic range, simulating background blur, or sharpening zoom. It's why two phones with similar hardware can take very different photos, and why software updates can change colours after launch — as one PixProof below shows.
Reading camera scores
DxOMark is the best-known lab ranking for phone cameras. Its methodology is documented, but how sub-scores become the headline number is proprietary, and it isn't a simple average. Treat any single score as one opinion, and look at sample photos in the conditions you care about — low light, zoom, video.

HYPE OR REAL?
"The Vivo X300 Ultra's colours matched professional cameras right from launch."
The answer: Hype. Notebookcheck measured very high colour deviations at launch — Vivo only improved it with a later software update.

- Is a 200MP camera better than a 50MP one?
- Not automatically. More megapixels means more detail in good light, but sensor size, the lens and processing matter more for low light, colour and zoom.
- What is computational photography?
- Using software to improve photos — merging several frames into one, reducing noise, balancing bright and dark areas, blurring backgrounds or sharpening zoom.
- Are DxOMark scores reliable?
- They're a consistent lab test, which makes them a useful signal, but the way sub-scores combine into the headline number is proprietary. Compare sample photos too.
