Google recently introduced the option to change the DPI density of the display directly from the Settings application, using a simple slider with large, medium and small values ??that you can easily adjust. If your phone is running the latest version of Android Nougat, you can find this option in the Settings application in the Display option with the possibility ofreduce and increase PPE densityscreen on your smartphone with Android Nougat.
DPI (Display Per Inch) or (Dots Per Inch) – Display per inch. The value set as DPI density essentially determines how many pixels will be displayed per inch on the phone display. For example, if you set the default value as 400, 400 pixels per inch are displayed.
The ideal value for each phone is to set the DPI to the factory default values. However, you can change it to fit your needs. If there is a display problem with the content on the screen during the change, you can change the DPI value to a number lower than the default value until you are able to perfectly view the contents on the screen.
The DPI value could also be increased to meet the need to get more content on the screen. If you change the DPI from 400 to 420, the display will be adjusted to display more content than before. In essence, a higher DPI value means that the contents on the screen become larger, while a lower value means that the content becomes smaller, displaying more text or images as in the following figure.
