@sinbad @KeefJudge Never had that problem in ~5 years of various USB-C phones - and I keep my phone in jeans pockets all the time?
Also, I'd echo Keef's comments - the USB-C cable should click into place, takes a concious effort to dislodge it. I've had some phone cases which don't allow enough clearance for the cable, but that's a different problem (and nothing that a few minutes with a craft knife haven't been able to sort out)
