Most Android devices nowadays come with a hidden service menu that can be used to diagnose and test different aspects of the device to ensure they are working properly or not. Samsung’ Galaxy S8 is no exception here and comes with a hidden service menu as well.

Considering the sheer number of hardware components and gadgetry the Galaxy S8 packs, using the service menu to check the various aspects of the phone before buying it, especially if there is no option of returning or getting a replacement unit if any issue is eventually detected in the phone. The service menu can come in particularly handy if you are buying a refurbished or second-hand unit of the Galaxy S8 or S8+ as you can check the device thoroughly for any hardware defects before buying it.

How To Access Hidden Service Menu on Samsung Galaxy S8 and S8+

Step 1: On your Galaxy S8 or S8+, open the Dialer/Phone app and key in “*#0*#”. As soon as you key in the code, the service menu will open up and the screen brightness on the handset will turn up to the very maximum.

Step 2: With the service menu open, you can now test the different aspects of the Galaxy S8. Certain tests will require user input like the touch screen test, while in others, a diagnostic test will automatically run itself and show you the final result.

This hidden service/diagnostic menu is also a great way to test your Galaxy S8 for any kind of hardware defects. If your Galaxy S8 ends up failing a particular test, you’d know for sure that it is faulty and would have to take it to your nearest authorised Samsung service centre.
