iPhone 6's camera has 8 megapixels and the Galaxy S6's has 16, but they take pictures with similar sharpness and clarity. So why does that happen?
It's understandable that most people think higher megapixel counts lead to better pictures. Megapixels have been the main point of measurement smartphone manufacturers use to tell people how good their mobile device cameras are.

Theoretically, more pixels should make a sharper image, similar to how more tiles make a more detailed mosaic, but that's not exactly the case.Pixels rest on your camera's sensor to capture light.
The larger the sensor, the more pixels it can support which often leads to better, sharper pictures. But as more pixels are added to a sensor, the smaller they need to be to fit onto the sensor itself. And the smaller the pixel, the less light it can capture, which results in images with "noise," or unwanted artifacts that reduce an image's sharpness.

so how now what should we watch out for when trying to buy a phone with a good camera.

You should go for higher pixels and sensor for better result.

How do we know the level of the sensor?

Boring

If it's really by sensor size, then China phones are gonna have the best camera quality.

If true then manufacturers need to start stating these details for their fans.
