Learn to Change DPI on Galaxy S7 and S7 Edge Smartphones

by Mike Blass · April 27, 2016

We all know that all latest Android phones may come with high-resolution displays, but the software screen density on most devices is set so low that it negates any benefit of a higher resolution display. After all, a higher Quad HD resolution display should display more information than a Full HD resolution display.

The screen density is one of the parameters used to distinguish a display and is completely different from the screen resolution. For example, the popular Samsung Galaxy S7 and S7 Edge smartphones come with a 2K display and a screen density of 640 DPI (Dots Per Inch). We can easily change the screen density of the Galaxy S7 and I am talking about using a third party app which requires root access.

Anyway, you can get the very same result with the help of an app that accesses the hidden native DPI scaling menu on the S7 duo to change the DPI to 560 with no scaling issues. All you need to do is head over to the Google Play Store and download this app known as Display Scaling (use this link for that) and select the condensed mode to change the DPI to 560. If you like the change, all you have to do is to tap on Done at the top-right corner of the display.

However, if you dream to change the screen density to any other value, then this tutorial will help you. To get prepared, install the handset’s USB drivers on your computer and don’t hesitate to enable USB Debugging on your device. For that, go to your device’s Settings » Developer options and click on the USB debugging checkbox.

And it’s better to be safe than to regret later, so plug in the charger I the device has less than 60% battery.
