How to Change DPI in Any Android Device (No Root)

Last Updated: June 15, 2017

Have you ever come across a situation where the text on your smartphone just seems too big? Or you just prefer to have more data shown on your display? Remember how you could simply change your screen’s resolution on your PC and it would automatically change the text on your screen? The same effect can be achieved by altering the DPI on your Android smartphone. DPI refers to the Density Independence on your device, which is the ratio of your device’s resolution to the display size. Simply put, a higher DPI results in more content being shown on your device. So, without any further ado, here’s how you can change DPI of your Android device:

Changing DPI on Android Nougat or Above (7.0+)

Starting with Android Nougat, Google introduced a simple and easy way to alter your device’s DPI, by offering an option in the Android settings itself. You can change your DPI on Android Nougat by following the steps below:

  • Open your device’s “Settings” and head over to the “Display” option. You’ll be presented with an option to alter the “Font Size” and “Display Size”.

  • Tap on “Display Size” to alter the DPI of your device. Move the slider to change the display size according to your preference. You can change between “Smallest” to “Default” to “Large”.

  • Additionally, you can alter the font size as well. Go back and tap on “Font Size” to alter the font size as per your preferences. Simply use the slider to alter the settings and get the changes in real-time. The settings for font size go from 80% to 100% (Default) to 130%.

3. If your device is rooted, you’ll be presented with a screen that says that “root access has been granted”, and you can proceed with the seventh step. If your device is not rooted, you’ll be presented with a screen that says that the app could not obtain root access and would require you to run a command via ADB to proceed.

6. In the Command Prompt window, first type “adb devices” without the quotes. If the system returns a system value with the list of devices, that means that your device has been successfully connected to the PC with ADB shell. If not, make sure you have the right set of drivers installed. Once your device name appears, type in the following command in the CMD window and press enter:

adb shell pm grant com.zacharee1.dpichanger android.permission.WRITE_SECURE_SETTINGS

CMD Commands

7. The aforementioned command should give the app the permissions it requires. Once done, tap on the arrow on your device to proceed. You’ll be presented with a screen that says that the setup is done. Tap on the tick icon to proceed.

Setup Complete

8. Upon entering the app, you’ll be presented with a screen that displays your device’s current DPI values. Simply enter the desired DPI value in that section and tap on “Apply”.
