Samsung Galaxy S7 Service Menu: The Galaxy S7 service menu grants access to a hidden menu on the Galaxy S7. This menu allows users to test the hardware/features. The service menu is useful if you need to troubleshoot issues with the Galaxy S7 (see here, here & here). Users can test sensors, make sure the touch screen is functional at all points of contact as well as test colors and more.
- Launch the Phone app on your Galaxy S5 and open the dial pad.
- Type * #0* # (no spaces)
These are the only two steps that allow access to the S7's hidden menu. Once opened, users see a screen of gray tiles with various settings to test. You now know how to open the Samsung Galaxy S7 Service menu.
There are many features that users can test via the Service Menu but the ones that most people tend to show interest in are the following:
- RGB Test- Tapping the red, green, and blue buttons along the top are an easy way to check for dead pixels on your display. Once you've inspected, just tap the screen to go back to the main Service Menu.
- Touch - This test lets you test the accuracy of the touch screen on your Galaxy S5. Trace the outside square and the inside X with your finger to make sure the touch screen registers the individual squares you're going over. Tapping the screen shows you where the touch screen registers your taps as well.
- TSP Hovering - Similar to the Touch test, this lets you test how sensitive your Galaxy S5 is to hover your finger over the display. This is used for Air view and if you think it's not functioning properly, give this test a try.
- LED - Performing the LED test will cycle through red, green, and blue notification LEDs so you know they're all functioning. Just tap the screen to move to the next color until the test completes.
- Sensor - This menu is for more advanced troubleshooters and tests all the sensors in your device from the accelerometer to the gyroscope and everything in between. It's not one that everyday S5 owners will probably understand but it could be very helpful for technicians or those that are tech savvy enough to understand what everything under the Sensors tests means.
Some tests require you to finish them before exiting so keep that in mind when starting a test. When ready to exit the Service Menu on your Samsung Galaxy S7 tap on the back button to return to the Phone app. As always, be careful when using any menu and don't ever change any settings unless you know what they do.
