You are literally the first person who has confirmed my suspicions and I'm pretty sure I scoured the entire internet!
Questions for you: who is your service provider? On Cricket, I experience this, but on T-mobile I do not. Also, which model of phone do you have, H850 or H860? That question doesn't really matter as I experienced this on both.
It's a shame. The work around is to force 3G, but then I don't get a very reliable streaming connection on Tidal. Mine is definitely software related. At first, I thought it was the physical connection given the nature of how it sounds and what happens, but it's 100% something to do with the cellular radios. I'm living with it currently, but I'm far from pleased with the situation.
Edit: just noticed you're in Australia. Hmmm, wonder if your carrier uses the same LTE bands as mine. I'm on Band 17, Band 4 and Band 2.
