Learn to Change DPI on Galaxy S8 and Galaxy S8 Plus Smartphones

Many people are perfectly aware that great smartphones come with high-resolution displays. Some of the most tech-savvy users, however, can easily make the best of their Samsung Galaxy S8 or Samsung Galaxy S8 Plus phones by tweaking the screen density.

A display with a higher Quad HD resolution should be able to display significantly more information than one with a Full HD resolution. But do you know how to pair the benefits of an extended resolution AND density?

Just to be clear, these are two completely different notions. The screen resolution is labeled in K – the 2K display of a Samsung Galaxy S8 or Samsung Galaxy S8 Plus. The screen density is labeled in DPI, which stands for Dots Per Inch – again, the 640 DIP density of the same flagships from Samsung.

If you’re interested in changing the latter, many would tell you to use a third-party app that requires root access. We, on the other hand, advise you to try the Display Scaling app available for download with this direct link, straight from the Google Play Store. This one will easily access the so-called native DPI scaling menu, which is generally hidden, and adjust its value to 560 without any kind of scaling issues whatsoever.

In a nutshell, you will have to download the app, tap on the Condensed mode, adjust the DPI to 560 and hit the Done button if you’re happy with the results.

The alternative consists of our instructions from below. Feel free to use it in case you want more flexibility and the option to adjust that value to anything else than 560. Make sure you install the USB drivers in advance, enabling the USB Debugging mode as well (go to Settings, tap on Developer Options, tap on the checkbox of the USB debugging option).

Just make sure you have at least 60% battery when you start and just follow these instructions:


To change the DPI on Samsung Galaxy S8/Galaxy S8 Plus…

  1. Download the ADB files on your computer;
  2. Extract the files in a very specific and easy to access location;
  3. Navigate to that folder where you have extracted the files;
  4. Identify an empty space inside the folder and use the Shift key and the Right click of the mouse, in that empty space, to open a command prompt within that folder;
  5. Tap on the Open command window in here, option available under the Windows context menu;
  6. Use a USB cable to connect the Samsung Galaxy device to the PC;
  7. Use the ADB devices command just to make sure that the computer detects it;
  8. Set the screen DPI to the specific value that you desire by entering this command: adb shell wm density DPI_Value && adb reboot;
  9. Naturally, instead of the DPI_Value you are supposed to insert your desired DPI value;
  10. The smartphone will automatically reboot after that.


And your quest of changing the DPI just ended successfully. In the future, whenever you will want to return to the original value, repeat these steps and enter the command adb shell wm density 640 && adb reboot and it should switch back just as easily. Enjoy experiencing with your Samsung Galaxy S8 or Samsung Galaxy S8 Plus in this direction.
