I have always had the same issue.. You can tell all S21 owners because they are walking sideways trying to use maps 😂😂 .. Anyway, I decided to go through the extended performance of the support chat and after the usual obvious Q&A. (and the chat person acknowledged that their phone was doing the same !!!) They said the developers were aware of the issue and working on a fix ?? for well over a year ??
Anyway,,,, I was eventually told to go to setting and delete the data for maps and restart the phone - surprise surprise that seems to have fixed it..
Clear the data of the 'Maps' app.
To clear an app's data:
1. From the home screen, swipe either up or down to access apps.
2. Select Settings.
3. Select Apps.
4. Select the sort by icon next to 'Your apps'.
5. Select the switch next to 'Show system apps' and select OK.
6. Select the app you'd like to clear.
7. Select Storage.
8. Select Clear data.
Turn your device off for 20 seconds, and then turn it back on again.
Hope it works for others..

The Magnetic sensor test gets a "FAIL" , any ideas besides repair center?
I tried this but it didn't work. It calibrates briefly but within a day or two I'm back to low accuracy and can't use my navigation system because I'm getting directions from two blocks away from where I actually am. The solution from Samsung is to send it in since it's still under warranty so I would just be without a phone while they try to figure out how to fix it or replace it. It's completely an unacceptable solution. This is so frustrating... it's my first Samsung and will probably be my last!?
thanks!! this solved the issue for me.
