Most smartphones these days come with a high-performance inbuilt camera. Picture quality keeps on improving with newer and newer releases with superior image sensors and higher megapixels. With the competition in the market getting tougher every year, cell phone companies have started adding two or three lenses instead of a standard single lens.

Things to understand about a camera phone before buying


This is the first and foremost thing to look at if you are planning to buy a camera phone. Wider the aperture, higher is the picture quality and vice versa. Smartphones such as iPhone 11 Pro, Google Pixel 4, Samsung Galaxy Note 10 Plus & Huawei P30 Pro have a relatively wider aperture, which ensures better picture quality.

Image sensor

When it comes to picture quality,  image sensors should be given the topmost priority. 

The primary role of an image sensor is to capture the light image and convert it into electrical signals. Larger sensors are equipped to capture more light than smaller ones. 

For example, an 8MP camera with a larger sensor could outsmart a 13MP camera with a relatively more minor sensor. It’s all about capturing the amount of light. If a sensor catches more light, it will produce better quality images.

Megapixel (MP)

This refers to the amount of pixel count that a camera has. The greater the pixel, the higher is the resolution. In a simpler sense, it refers to the number of details in an image. 

You might have often noticed that resizing a picture taken on a lower megapixel camera will often make it appear pixelated. For a good quality picture, it is necessary to have a minimum of 12MP camera, which can create an image quality of 11 x 24″.Going anything beyond that will reduce the image quality.


Smartphone designers have come up with a variety of sensors to make smartphones as compact as possible. Premium smartphones often come with lenses with a better aperture as similar to that of the ones found in digital cameras.

Instead of a single fixed lens, smartphone cameras come with two or more lenses with different focal lengths.

It’s better to choose a dual camera smartphone for better image quality. Dual camera phones come with a telephoto lens and a wide-angle lens.
