Samsung Galaxy Note 9 Open Service Menu - Secret Code

Each Samsung smartphone has a small service menu integrated, which cannot be opened via the Android interface, but only via a special code.

That's why this is often called a "secret menu". What is so special about this secret menu on the Samsung Galaxy Note 9?

In this service menu you can run tests and check the hardware for technical functionality. This is very useful, for example, if you think the camera has a defect, the display has a pixel error, or the touch sensors no longer function correctly.

 In this menu you can simply check the hardware with a test, because only standard drivers are loaded in this menu.

In the following we will explain how to call the service menu on the Samsung Galaxy Note 9:

1. First open the phone app from the start screen and change to the keypad (number pad)

2. Now enter the following code: When you have entered the last hash, the service menu will also appear on your Note 9 display.

You can now select the individual fields and perform tests or read out sensor data.

Here we recommend you to have a look at "Sensor" because it shows a lot of interesting data that the sensors of the Samsung Galaxy Note 9 collect.
