Questions about the Fairphone 5

USB reverse tethering is internet from the PC to the smartphone by USB, it was a feature of Android: USB-PC internet share Is it possible to have reverse tethering working with Google Play ? - Android Community , googling “usb-pc internet share android removed” I even not found an answer…
I guess I’ll use the 3rd party Gnirehtet GitHub - Genymobile/gnirehtet: Gnirehtet provides reverse tethering for Android , re-Link is a payware re-link - reverse tethering made easy

Well has anyone UVC working?

USB mass storage device class - Wikipedia , e.g. my old smartphone Logicom L-ement 403 with Android 6.0 (as in the 1st link of this post) has USB mass storage, but only for a microSD card plugged to, not its internal storage… but the PinePhone Pro yes. E.g. I can create, delete a partition on the microSD card.
Again USB mass storage was a feature of Android, googling “usb mass storage android removed” I found https://www.reddit.com/r/Android/comments/1aqjd0/why_do_new_versions_of_android_not_support_usb/ .

Well at least the PinePhone Pro can boot a microSD card…

No jack anymore yes but why not the headphones cable as antenna plugged to the USB-C of the smartphone?
