5. Further in the "Explorer", open the folder in which the ADB.exe file is located, click on the Address field and copy the path from there.

   

   Return to the "Command Line" window, enter the CD characters, then place the space, insert the path copied earlier and again use the Enter key again.



6. Go to the phone again - connect it to the PC and allow debugging access.



7. In the "command prompt", enter ADB devices and make sure the device is recognized.

   

   If the list is empty, disconnect the phone and try to connect again.

8. Use the following command:

   ADB Shell Dumppsys Display



9. Carefully scroll through the resulting list, find a block named "Display Devices", in which the "Width", Height and Density parameters are responsible for the resolution in width and height, as well as for the density of pixels, respectively. Remember this data or write to set them back in case of problems.



10. Now you can go to edit. Enter the following:

    ADB SHELL WM DENSITY * Number *

    Instead of * Number * Specify the required pixel density values, then press ENTER.



11. The following command looks like this:

    AdB Shell WM Size * number * x * number *

    As in the previous step, replace both * number * on the data you need: the number of points in width and height is respectively.

    Be sure to make sure between the values ​​of the X symbol!



12. To change the changes, the phone needs to restart - this can also be done via ADB, the following command:

    ADB reboot.



13. After re-launching the device, you will see that the resolution has been changed. If after downloading you encountered problems (the sensor reacts poorly on the touch, the interface elements are too small or large, the part of the software refuses to work), then connect the device to the ADB again and use the commands from steps 9 and 10 to install the factory values ​​received in step 8 .

The use of Android Debug Bridge is a universal way that is suitable for almost all devices.
