Activating the Diagnostic Tool
In this tutorial, We will use a Galaxy Note 2 since it’s the only device that I have with me right now. The diagnostic menu on Galaxy note 2 literally check the device condition with different diagnostic tests and return the results to the user. This menu is embedded into the system and doesn’t require any rooting at all. To access the hidden diagnostic menu, all we have to do is to dial in simple command on the Galaxy Note 2 phone dialer as shown below.
Diagnostic Tools Menu
After entering the code above, it automatically shows a full screen menu with the following diagnostic tests to determine the device status and current health of device.
