What are megapixels?
To understand the term megapixels, first, you need to understand what a pixel is. A pixel is a dot in your photo, and your picture is made of millions of dots. There are one million pixels in a megapixel. The light has been captured by each pixel and turns it into data. This data has been combined to create an image.
The quality or detail of your image will be automatically improved with the more pixels. It is not necessary because the pixel captures both good and bad information which include saturated appearance, quality of colors, low light and grainy. These all can make the photo bad. So, more megapixels are useful to capture the information, but it collects both the good and noise (bad) data which can ruin your photo even if you have a high megapixel camera in your phone.
Is more megapixels mobile camera better? No.
Camera MP Size Don’t Decide Better photos. It is not necessary that the quality of the photo will automatically improve just because you have captured it from a high megapixels camera. The sensor of the camera plays a significant role to make the picture perfect, Software also makes an important role.
Let’s take an example of a 12MP camera phone and a phone with a 20MP camera. By know, you must know that the 20MP phone camera will make a better photo but what if it has the same sensor which a 12MP phone camera has? A picture taken from the 20MP camera would be better, but it could be equally worse if the size of the sensor is not improved according to the number of megapixels. To get a better photo from the 20MP camera, the size of the sensor should be smaller. To Better Understand I attach the Samples Below. The photos are taken without using any filter. Used Mobiles are Samsung Galaxy J7 2015 (13 MP Rear Camera) and Google Pixel 2 XL (12.2 MP Rear Camera).
Let’s take the example of Google pixel 2 and three which have only 12.2 Megapixel as a rear camera but works better than all of the devices. You can Easily notice how much details and Noise reduction happened in Pixel 2 Devices. However, some devices have a 16+20 MP rear camera, but they are not well. It purely depends on the Good camera with a proper Optimization technique and the size of the sensor.

It is good to go with a less megapixel mobile camera because it will upload the photo fast.
If you want to print a photo, show on a digital TV or print for the billboard, then you probably need a high megapixel camera. But again, if you are displaying a 5 MP image on a Large TV screen, the quality of the image will not be improved but get worse because the image will be automatically scaled to fit with the size of the TV screen.
So, the number of megapixels does not matter until and unless you don’t know its purpose. The formula for picking the right phone by megapixels of the camera is simple. If you want to print the image, go with a high number of MP cameras.
