Audio over usb works fine at usb 2 speeds.
Hell, professional audio interfaces from major brands like RME, with full support for 16+ channels simultaneous in/out high rate audio work fine at USB 2.0 speeds.
I was arguing against having any data connection at all (and just fixing the bluetooth stack).
The only port I want at all is a headphone jack, and that’s easily waterproofed. Since we can’t have that, I was hoping they’d remove the charge port entirely.
This is the first time I’ve ever used data over USB on this phone though. I wish Apple had better testing for their bluetooth stack.
