Welcome to the Android world where even good smartphones worth 400 $ only support USB 2.0
I don't use data on the USB port very often and when I do it's always to make an access point over USB so the USB2.0 bandwidth is enough for my use.
I wonder if people really have a use for USB3.
Apart from making phone more expensive, I don't see a real need for me
Argument can be made if your camera doesn't support 4k or 60fps, there's very little need for higher speeds than USB2.0 since files generated won't be as big. However if you keep using your phone as a camera to record long videos, then yes it's annoying to have slower interface.
That's a valid point.
Also is there's a USB3 controller at all in the phone to connect the camera inside the phone? Or does the camera talk on a different bus on the SoC?
With Apple devices I honestly don't know. With others SoC is the one exposing the rest of the hardware and acts are intermediate. Historically in general giving DMA access to any hardware on the system has proven fatal when it comes to security. You do gain speed, but expose so much in the process.
