My phone has IP68 with an usb-c and headphone jack, and the SIM/SD tray. Not a rugged phone though.

so would it be accurate to say that if one were to take a frame of reference on a large scale, say, the absolute centre of the universe (I know, but bear with me on this one), it’s also fairly impossible to travel back in space as well as time, seeing as by the time it takes you to take a step back to your original position, the earth has already moved enough that you are no longer there relative to your reference?
