This guide is used to change the DPI in our device without the need to root it, which translates into improved readability in some programs. In this guide, I will show you how to do it for phones running on the MIUI 9.

NOTE: The procedure described in this guide presents complicated operations that may damage the device in the event of a malfunction. It is recommended to carry out modifications only by users who have experience in the field of modification. Techlector staff is not responsible for any damage to the device.



  • USB cable
  • ADB and Fastboot drivers installed on the computer.


  1. First, you need to enable “developer options”:
    1. Go to settings → About phone ⇒ Click “build number” 7 times to enable “developer options”;
    2. Go to settings → developer options → select USB debugging.


  1. Turn off WIFI, activate data transfer and make sure your device is connected to the Mi account;
  2. Install TunnelBear VPN  and set up the connection on a server in China or Hong Kong;
  3. Go to settings → programmer options;
  4. Go to USB Debugging (Security Settings) and make sure all three check boxes are selected;
  5. Open a command prompt and run the following command from ADB;
  6. adb shell 
    wm density 380 
  7. In this example, you set DPI to 380, but you can also set it to smaller;
  8. To reset DPI to the frog settings, run this command;

    m density reset 

The modification is permanent and will not disappear the first time you restart your phone.
