Samsung has given each of its smartphones, including the Samsung Galaxy Alpha, a so-called test-menu, which is also called service or secret menu. This menu can be used to test the functions of hardware components independently of the Android operating system .
To display the test menu on the Samsung Galaxy Alpha, you must follow this step by step guide:
Open from your Home screen the phone app. Switch within this app to the "Keypad" and then enter the following code on the keyboard:
When you enter this code, a new menu with different gray tiles on a white background will be displayed. Each of the tiles represents a hardware test. For example all sensors that are integrated in the Samsung Galaxy Alpha, can be tested under "sensor".
To exit the test menu, tap quickly twice on the Samsung Galaxy Alpha back button.
You now know where you can find and open the Test menu on your Samsung Galaxy Alpha.
