That's (a) hard to believe and (b) in the minority if true. I think this stuff works so poorly all the time that some get accustomed to it or some are just lucky. I had it happen on my desktop computer and the monitor's audio today because the audio device got confused after a Remote Desktop session. There wasn't even a wireless connection involved. I had to run to get wired headphones. If anything, in my experience, it is service providers' cell coverage and cell reception on phones barely designed to be phones that are all so abysmal that it doesn't even matter if everything else works well. They alone make cellphones terrible as phones when on cellular. And in general, BlueTooth sucks. I need to do an incantation to keep my PS4 controllers connected, a problem reported by many in various forums.
