adb shell dumpsys display

The adb shell dumpsys display command is used to obtain information about the display settings and configuration on an Android device. This command provides details about the current state of the device’s display, including information about connected displays, display metrics, refresh rates, and more.

Here’s how you can use the command:

$ adb shell dumpsys display

The output will include information about the display-related settings and configurations. This can be helpful for debugging display-related issues, checking the display properties, and understanding the current state of the device’s screen.

You can also redirect the output to a file for further analysis:

$ adb shell dumpsys display > display_dump.txt

This will save the output to a file named display_dump.txt in the current directory.

Keep in mind that the output can be extensive, and interpreting the information may require familiarity with Android display subsystem internals. Always refer to the official Android documentation and relevant resources for a deeper understanding of display-related settings and configurations.

Using dumpsys commands provides a way to inspect the internal state of various system services on an Android device, which can be valuable for debugging and performance analysis.
