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)
headphone jacks are still available for mid ranged androids, even along with a charger. pretty much the only win we can get for purchasing a mid ranged androids.
Not being ridiculously overpriced is another advantage imo.
