Alternatively, change the pixel density in developer mode. Go to

- Android DPI can be as low as 120 or as high as 640 (this may vary from one model to another). The larger the number, the smaller the on-screen items (text, icons, etc.) will appear.
It's at the bottom of the pop-up window. Doing so will adjust your Android's pixel density.

Question
This completely ruined my S7. Now I can't turn it off or factory reset. What do I do?
Community Answer
You have to connect the device to a computer and use ADB Shell to change the resolution back to original. Messing with Android system files can and most likely will brick your device. Always think about that before changing anything.

What should I do if 'Adb' is not recognized as an internal or external command, operable program, or batch file?

On Windows, you need to enter .\ before you run a program from command prompt or Powershell. In this case, you need to enter ".\adb shell" and it will start the connection with the device. You should have a new prompt where you can enter the rest of the command from above.

You may notice distortion with your Android's on-screen keyboard after changing the resolution. You can install a keyboard that scales with DPI (such as GBoard) to fix this issue.

Warnings

While you can scale your phone's resolution up or down to increase or decrease the size of things on the screen, you can't increase your Android's resolution to a higher definition (e.g., 720p to 1080p) since definition is dictated by the Android's physical screen itself.

In some cases, changing your DPI will cause compatibility issues when using the Google Play store to download apps. If you encounter this issue, you can change your DPI back to the original settings, download the app, and then change the DPI again.
