It would be a very strange design approach to add an “backup” port. I think there are alreay gaming phones that have it? But for the normal person this seems to be odd.
I would like that we can exchange those ports without removing the display… i had two phones that had broken usb c ports. A good thing we have wireless charging.
On Android there is xManager (Spotify) and Revanced for YouTube Music. I didnt encounter that many problems over the years. You dont get HighBitrates, but everything else works.
