Hi,
I’ve been using a FP3+ for over a year, stock Android kept up-to-date (though as I write, still on 3.A.0129). I just checked, I don’t have this problem and haven’t seen it. I conclude it might be a tricky one to reproduce, diagnose and fix, and is not fully blocking a fuctionality, just a bit of a nuisance.
P.S. - just a thought about the Bt icon thing: … but I’m taking the conversation over to the other thread…
