One should be at the bottom one at the top. I understand space on the phone is a premium but a second port would make the phone so much more usable. Wired headphones, flash drives, camera modules, speaker modules, keyboards, even connection to a TV, all could be used while charging. It’s a shame it’s not a thing, USB is extremely versatile port, but you only get one and it’s used for charging half of the time. (I am aware dongles exist)
Weird headphones don’t use ucb-c, there is already a standard for headphones and it’s the 3.5mm audio jack.
That’s not the only standard though. There is also 6.3mm jack, XLR and many other open and proprietary connectors.
I want XLR my next phone! 😀
