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.

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).
