DPI And Screen Info is a free utility app that will help you determine the Pixels per Inch (PPI) of your Android device. It is an application for measuring the pixel density of displays such as mobile screens, laptops, and televisions.

The application is based on the concept of Pixels, which is a fundamental unit in the graphic representation of data. Each pixel contains a color and a specific quantity of data. In most cases, each pixel is represented by a number. However, in the case of the DPI, a pixel is defined as a group of 4 numbers (or 8 numbers in the extended version).

The application allows you to measure the PPI of devices with a display size in inches. It also provides you with an option to measure the PPI of the current display or the PPI of the device on which the application is installed.

It is a very important measurement to determine the quality of the display of your device. The higher the PPI, the better the display quality. The application provides you with a list of devices with a known display size.
