Hi,

Yes, we are quite a few with this problem, check the forum for other threads.

No know fix so far, we are kind of hoping for an update to fix this, but I didn't see any communication from Samsung...

Some users of the Google Pixel 6 have reported the same proble. It's my understanding that the S21 series and Pixel 6 use the same chip? Anyway, hope they get it sorted sooner rather than later!
