Larger camera sensors can capture more light, and with more light, there's usually more image quality potential. Keep in mind that many other factors, such as megapixel count, wide aperture, and ISO, impact photography results.
Sensor size used to be something only professional photographers would care about, and it can also provide information regarding the diagonal crop factor. Yet, thanks to smartphone photography evolution, mobile cameras have developed into sophisticated systems with professional image quality potential, and everyday users are expanding their knowledge and expectations. When choosing a smartphone for photography, consumers may also take sensor size into account. This information may be expressed in fractions of inches (e.g., 1/1.33") or, as displayed on Versus, in millimeters.
Bigger sensors have more photosite space, which translates into more light capture and is especially useful in dimly lit environments by decreasing noise and increasing sharpness. Moreover, larger sensors can give room to larger pixels, making for sharper images compared to the same amount of smaller megapixels.
