Same issue in 2022. I've been hoping monthly software stability/security updates fixed this but they don't. Such a shame. And apparently Samsung doesn't read these posts either.
I have exactly same problem since I got S21 ultra new in Nov last year. Haven't found solution yet. I observed the error is at about 45-90 degree clockwise. I have to move while watching map to work out the direction everything which is frustrating. Just start to look for a solution on internet
Has anyone managed to find a solution to this problem?
Unfortunately not I've still has this issue.
I use my galaxy watch for navigation in cities because the S21 Ultra is so bad with its compass.
I have the same issue with my S21 Ultra and it is already April 2022... Trying to navigate on foot in a city like London is a nightmare with this phone due to the 90 degree error in the positioning...
Samsung, fix this!!!
I too have had this issue from day 1 of owning the s21 ultra. The problem is so bad I cannot use it for walking navigation, which should be core function of this device. I'm tempted to start a class action lawsuit as many attempts to resolve this issue have failed and Samsung are not accepting liability for the issue.
Same problem, same exact 90 degrees, same diagnostics. I was using it to find the ISS for me to photograph with a proper camera and missed it because suddenly my phone is 90 degrees out (this was outdoors).
Went into google maps, can't find 'calibrate' anymore, but heads-up is 90 degrees out. Did all the figure 8s anyway, no change.
Restarted the phone and it seemed okay. Nope. I stood in the middle of the room facing south with it showing S then sat down at the coffee table, boom - 90 degrees different again.
To rule out a gigantic electromagnet hiding in the couch I stood up and faced south on the same spot again. Still wrong. Then I tried Dioptra - worse, rotating it goes N (when facing South) then as far as NNE and starts going back again.
Sidebar compass keeps saying calibrate and it doesn't last more than a minute.
I also face this issue dayly.
I walk sideways like a crab, but it's not a good solution.
I just started having this issue with my S21 Ultra last month. It will hold the calibration for a day or two Max and then it's back to the same issue, it thinks I'm in the middle of the water or driving off road next to the highway and the directions are all wrong. I rely on my GPS to get me to clients homes and search and rescue locations on a daily basis. I hope there's a fix ASAP otherwise I'm going to have to return the phone. I've only had it a couple of months and like everything else about it 😒
