Cases with a magnetic closing = compass issues?

[user91]

So, just like anyone else, I´m also looking at tonnes of cases before I get the phone.

I´d have one question I haven´t seen in the forums here yet - even Samsung offers cases for Galaxy S8 that have magnets in them, e.g. the official clear view case. Won´t the magnet in it have negative impact on the compass in the phone? My elementary school memories tell me that magnets and a compass are not the best friends. I use my phones a lot for navigating around and this would be quite an issue.

Would anyone with more technical knowledge care to chime in on this?

Thanks a lot!

There's not a real compass in the phone. It's based off of the gps and accelerometer. So don't worry about magnets. I have a magnetic car mount for my phones, and none of them have ever had problems.

This is incorrect. Almost all modern smartphones use the magnetometer for the compass.
The accelerometer and other sensors only improve accuracy if used.

I cannot comment on whether a magnetic case would mess the sensor up.

You might be able to use this tool (Not sure if its in the S8) to see if the magnet is interfering

Turn on the Samsung Galaxy S7 or Galaxy S7 Edge
From the home screen, select on the phone app
Switch to the keypad
Type *#0*#
Then select on the “sensor” tile
Browse to the “Magnetic Sensor”
Now move the Samsung Galaxy S7 completely around each axis
Move the compass sensor of the Samsung Galaxy S7 until its completely calibrated
Exit the service menu by repeatedly tap the Back button
