Samsung Galaxy S8 How to Calibrate Compass – Instructions

The Samsung Galaxy S8 has a magnetic sensor installed, with which you can determine the magnetic north pole. This is useful, for example, to use the compass app in the Edge bar. However, it may be that this compass indicates the wrong direction of the sky.

If this is the case, then the compass of the Samsung Galaxy S8 must be recalibrated. Fortunately, you can do it yourself. We explain how it works:

  1. Opens the phone app and the keypad. Enter the following code:
  • * # * # 0
  1. This will now open the test menu of the Samsung Galaxy S8. Tap on the area with "Sensor" and then scroll down in the next menu.
  2. You will see "Magnetic Sensor" and below it a circle with a line and a number behind it. This has the following meaning:
  • Red line with a 0 = The compass sensor must be calibrated
    • Blue line with a 3 = The magnetic sensor is calibrated
  1. To calibrate the compass, rotate the Samsung Galaxy S8 around all its three axes. Make this until the circle shows a blue line and a 3. Only then your compass is calibrated. Any compass app that now accesses the smartphone's magnetic sensor should now display the correct sky direction.

So you have successfully calibrated the magnetic compass on the Samsung Galaxy S8.

You enter the code using the keypad of the stock phone app. The keyword there is "stock" — if you downloaded a third party dialer from the Play store for example, it won't work. The correct code is ᎓ * # 0 * #.

Btw, the fact of being able to enter certain key sequences into the phone's stock dialer in order to do all kinds of stuff is standard across all Android phones, going back to 2009 at least. It's done so that technicians can test certain features, both when the device is being manufactured and afterwards. You can Google to find out what all the codes are for your device model. Sometimes some of them don't work — it's easy for the odd mistake to slip in when you're typing out a page full of stars, pound signs, and numbers for web publication. If you do try some of them out, use common sense and be careful not to screw anything up in there by (e.g.) changing values without knowing exactly what you're doing.

What's the phone app? Where do I enter the code?

Where does one enter this code? Phone pad?

Indeed, the zero belongs in the middle, not on the end.

Incorrect code. Should be *#0*#

These codes never work on my phone. Do you enter *#0*# and then hit call?

No need to press call.
The moment you type the 5th character, it shows a menu with many boxes, one of which is Sensors.
Once in Sensors, you can self test many other sensors and see if all is good.
