I'm not going to tell anyone to "hold it different" because their use case is their use case, but your thinking tracks mine. I was SHOCKED to see how many people are saying "no second speaker, no sale". A second speaker is going to be tiny, which means it won't sound good. If you care enough about audio quality to say "nope, not buying that phone" I don't understand why you're listening to phone speakers in the first place.
I'm definitely not an audiophile, but my phone almost never makes sound. If I'm watching something: AirPods. I made myself use the single speaker to watch Formula 1 over the weekend and it was fine. I could absolutely tell a difference compared to the Pro Max, but they both sounded significantly worse than listening on my AirPods.
But I'm starting to think I'm the weird one. Given the forum's reaction, I definitely am. And, thinking about it more, I suspect "normal users" are probably more likely to just use the phone speakers, given what I see when I'm out and about.
