How to change the DPI on Xiaomi phone: 3 proven ways

The pixel density (DPI) on the screen of a Xiaomi smartphone determines how large or small the interface elements will be displayed: icons, fonts, buttons. By default, the manufacturer sets the optimal value for each device, but sometimes users want to adjust it – for example, to increase text for ease of reading or, conversely, to zoom in so that more information is placed on the screen.

In this article, we will discuss three working methods for changing DPI on Xiaomi, Redmi and POCO smartphones running MIUI 14/15 and the new HyperOS firmware. You will learn how to do this through the developer settings, with ADB or specialized applications, and what risks can arise if you do not configure correctly. Importantly, changing the DPI affects the display of all applications, so we recommend backing up the data before experimenting.

What is DPI and why change it to Xiaomi?

DPI (dots per inch) is the number of pixels per inch of a screen that determines the scale of the display of interface elements. The higher the value, the smaller the icons and text, and vice versa.

• 📱 320 DPI — large interface (comfortable for the elderly or visually impaired).
• 📱 400–480 DPI — standard value for most Xiaomi smartphones.
• 📱 560+ DPI — ultra-small scale (suitable for large screens, such as Xiaomi 14 Ultra).

Reasons to change DPI:

• 👓 Increase text for comfortable reading without straining eyes.
• 🎯 Optimize your workspace – put more widgets or shortcuts on the home screen.
• 🛠️ Fix display bugs in some applications (for example, if interface elements are cropped).
• 🎮 Set up games – some emulators (for example, PPSSPP) require specific DPI work-in.

⚠️ Note: Not all applications are properly adapted to the modified DPI. In some cases, you may experience cropping, broken buttons, or display errors, especially banking and hard-to-reference games.

On Xiaomi smartphones, the default DPI value depends on the model and firmware version.

Method 1: Change DPI through Developer Settings

The easiest and safest method is to use the developer’s built-in Settings, which works on all Xiaomi smartphones with MIUI 12 and later, as well as HyperOS. The main advantage is that you do not need to connect to a PC or install third-party applications.

Instructions:

1. Activate Developer Mode: Go to Settings → About Phone. Find the MIUI Version (or HyperOS Version) and tap it 7 times in a row. You will receive a notification: You became a developer!

Settings → Additional → For Developers

HyperOS

Settings → System → Advanced settings → For developers

Minimum width (in dp)

MIUI

320–560

OK.

Reboot your phone to make the changes take effect.

Activate Developer Mode (7 taps according to MIUI/HyperOS)

Backup of important data

Remember the current DPI value (in case of rollback)

Charge your phone at least 50 times%-->

If the minimum width is not available, try:

• 🔍 Enable debugging on USB (Settings → For developers → Debugging by USB).
• 🔄 Reboot the phone and reopen the developer menu.
• 📱 Update the firmware to the latest version (in older versions) MIUI This parameter could be hidden).

⚠️ Note: Some models (e.g. Redmi) 10A or POCO M4 Pro) modification DPI through the Minimum width can cause a failure in the launcher, in which case the reset of the launcher settings will help: → Annexes → Application management → Launcher → Warehouse → Clear the data.

💡

Changing the DPI through Developer Settings is the safest way, but it doesn’t work on all Xiaomi models. If the setting is missing, use ADB or third-party apps.

Method 2: Change DPI through ADB (for power users)

If the developer menu doesn’t have the right setting, you can change the DPI using Android Debug Bridge (ADB), a method that requires connecting the phone to a PC and basic command line knowledge, and benefits from working on all Xiaomi smartphones, including models with HyperOS.

What you need:

• 💻 A computer with installed Xiaomi drivers and ADB Tools.
• 📱 USB-cable (preferably original).
• ⚡ Included debugging by USB phone-on.

Step-by-step:

1. Connect your phone to your PC and select File Transfer mode.
2. Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with adb.exe.
3. Enter the command to check the connection: Adb devices must appear serial number of your device.
4. Find out the current DPI value: adb shell wm density
5. Change the DPI to the desired (for example, 400): adb shell wm density 400
6. Reboot your phone: Adb shell reboot

To keep the changes after the reboot, follow the additional command:

adb shell wm density 400 && adb shell am broadcast -a android.intent.action.CLOSE_SYSTEM_DIALOGS

💡

If the interface elements are not displayed correctly after changing the DPI through ADB, return the standard value with the command adb shell wm density reset.

Possible errors and their solutions:

⚠️ Note: Some HyperOS firmware changes DPI through ADB It can cause system applications to crash (e.g. Mi Home or Theme Store) and resetting settings through Settings will help. → Memory. → Backup → Resetting settings (without deleting data).

Method 3: Using Third-Party Applications

If the first two methods don’t work, you can use specialized apps from Google Play, which allow you to change DPI without ADB and often offer additional features, such as a separate setting for each application.

Top.-3 change-over DPI:

• 📱 App Settings (Xposed) – requires root rights, but offers flexible customization for each application separately. MIUI, It doesn't work on HyperOS.
• 📱 DPI Changer (No Root) - changes DPI through ADB Automatically (you need a PC for the first connection).
• 📱 SetEdit – edits system settings, including DPI. It works without root, but requires permission to change system files.

Instructions for DPI Changer (No Root):

1. Download and install the app from Google Play.
2. Connect the phone to the PC and allow debugging over USB.
3. Start DPI Changer and press Connect via ADB.
4. Enter the desired DPI value (e.g. 420) and press Apply.
5. Reboot the phone.

Advantages and disadvantages of third-party applications:

⚠️ Note: Apps like App Settings or SetEdit can cause errors MIUI/HyperOS, If you change the settings at random, on HyperOS smartphones, using these tools can lead to blocking certain features, such as Mi Share or Quick Ball.

How to Get a Standard DPI Back on Xiaomi

If after experiments with DPI interface began to work incorrectly, return the standard settings can be in several ways:

Method 1: Through Developer Settings

• Open the Settings. → For developers.
• Find the Minimum Width option and return the default value (see the table at the beginning of the article).
• Reboot the phone.

Method 2: Through ADB

adb shell wm density reset

Method 3: Reset the launcher settings (if the icons are missing or not displayed)

adb shell pm clear com.miui.home

For HyperOS, use:

adb shell pm clear com.miui.hyperlauncher

Method 4: Complete resetting of settings (extreme case)

• Go to Settings → Memory → Backup → Reset settings.
• Select Reset all settings (app data will be saved).
• Confirm the action.

💡

If the phone has stopped responding to touch after changing the DPI, connect it to your PC and reset it via ADB. 90% of the time, this solves the problem without losing data.
