I hesitate to ask this on the EE site because it's not really an EE question. I'm more interested in the mechanical forces that keep an USB plug from slipping out of the socket.
I am asking because of the common issue of USB-c plugs becoming loose over time, compared to USB-a plugs which do not seem to have this issue. I wonder what is reason behind this. Is the mechanical structure of a USB-c plug considerably different than a USB-a?
Also, last time I went to have mt phone checked up, I was told that the "sensor" of my phone is misaligned, hence why my plug keeps falling out. I don't understand what the "sensor" being referred to was, nor can I find it on the typical USB-c pin layout. Some explanations on this would be much appreciated.
