How to change the screen resolution on a device Android

I want to share with you another hidden property of devices Android, which, like many other things, is not available through the system settings. From my own experience, I know that not all manufacturers on their tablets default to a user-friendly display resolution. This is especially true for budget seven-inch tablets, where the working area is small, and the developer sets such a size of objects that in landscape orientation, the text on the display fits up to 4 lines, and this makes working with the device very inconvenient. Therefore, I want to tell you here how to change the screen resolution on Android.

How to find out the display resolution

First, I'll tell you what the display resolution is. It is essentially the number of pixels per unit area. For comfortable work on a seven-inch device, it should be at least 1024×600. With this value, the image looks comfortable; all values ​​that are higher only improve the quality, if the value is lower, everything on the screen will be large for the specified display size.

I want to show how to find out this parameter of the Android screen without the help of any third-party programs:

1. To do this, you just need to take a screenshot of the screen. By default, on all devices, this is done by pressing the 'Power on' key and the 'Volume down' key, after which the screen will be saved in the gallery.
2. After that go to the gallery and open the image.
3. Select the properties of the picture, where you can see its size (it will be equal to the size of your display).

Now let's move on to the main one: about the resolution on Android. In order to change the resolution of the Android screen, you need Root rights and any file manager (I will use ES Explorer)

3. Open the build.prop file with one of the text editors (ES editor in my case)

   

   

   Select the 'Operations' button and select 'Change'.

   

4. We need to change the value in the line ro.sf.lcd_density = (I have a value of 160), and change it downwards – I will put 130.

   

   

   Click Finish.

5. Save changes on exit.
