You can use the Tango test, manual test and see the test results
2:20
If you tap manual test for example you can choose one of the tests, for example speaker test
2:32
Alright if everything is alright tap pass. And you can also use other stuff for example Bluetooth, GPS, sensors, microphone, LCD test
2:44
as you can see right here. Alright let's go back and now it's time to open the serial number

You can also perform the factory reset by using secret code. Let me show you how to do it
3:23
You have to use Pound, Pound, Pound, Pound, seven, seven, seven, seven, Pound
