Hello,

This does not directly relate to android or android devices but as this seems to be one of the more active communities, I thought I should give it a shot here.

I'm Wondering why the USB C socket and plug have the geometry they have. To me, it seems like the more complex hardware is located in the socket which is located on the more expensive device compared to the cable. Firebolt (is that the apple standard's name?) seem to handle it the opposite by having the flat plug with bare contacts.

Background is that I have frequently had issues with charging my phone due to dust or other dirt getting suck in the socket. Lacking adequate household items, I had to use a small screw driver to get the dirt out, which I think in general a bad idea.

Are there any technical reasons to have the flat contact in the center of the usb socket rather than the plug?

The magnetic cables can short the pins never meant to be shorted by attracting random metal shavings. For microUSB it was relatively benign with only 4-5 pins (lots of space between them) and low voltage. With USB-C I wouldn't dare to try it due to it having much more pins and often much higher voltage (Power Delivery). It's perfectly possible to fry a device with a bad short in such conditions.
