Samsung Galaxy S3 Trick: How To Access The Hidden Service Menu, Lets You Self Diagnose For Faulty Device

Samsung Galaxy S3 Trick: How To Access The Hidden Service Menu, Lets You Self Diagnose For Faulty Device Samsung Galaxy S3Samsung Galaxy S3 users are always in search for tips and tricks for their beloved device. If you are one of those people then you have come just to the right place. Thanks to Gary Mazo from AndroidCentral we now have a way to unlock the diagnostic capabilities built in all the Samsung Galaxy S3 smartphones.

The service menu is originally meant for the professionals at Samsung’s official service center but since there is no authentication required, normal users can also access the service menu and diagnose their Samsung Galaxy S3 themselves just in case the device encounters any problem(or maybe just for the cool factor).


To start the hidden service menu on Samsung Galaxy S3 follow these simple steps

Step 1–> Start your Phone app(the app though which you dial phone numbers)
Step 2–> Get to the Keypad screen
Step 3–> Type in: *#0* #

If you have followed the instructions as stated above then you should have a screen with 5 X 3 grids on your Samsung Galaxy S3 with each grid being a different option like the one below.Samsung Galaxy S3 Trick: How To Access The Hidden Service Menu, Lets You Self Diagnose For Faulty Device Samsung Galaxy S3 Service Menu 168x300

The top row is meant for testing the color capabilities of the phone and to check whether the screen has any dead pixel or not. The second row has options to test Receiver(short high pitched beep heard when the button is tapped), Vibrator and Dimming( screen gets divided in three parts; red, green and blue then the screen gets dim to about half the brightness). Third row compromises of options like Mega cam, sensor and Touch which allow you to self diagnose the front camera, sensors like Proximity sensor and Barometer and the Touchscreen respectively.

The last two rows checks the Sleep functionality, Speakers, Sub Key, Front Camera, LED and LED frequencies. However, on tapping the sleep button your Samsung Galaxy S3 would go into the standby mode and the hidden service menu would have to be opened today.

This menu doesn’t provide much useful data for normal users but it is really nice to see that we can identify any problem in our Samsung Galaxy S3 ourselves and might also find a solution and also as said earlier, it’s cool.

    Some times, while the bell rings indicating an incoming call, I get on the screen adroid.com stopped functioning. I have to press ok key for the screen to become normal. At that time, the ring stops and I dont get to know from the log who called me. This happens atleast twice or thrice a day. Can any one guide me through to get over this problem
