3.5 jack, usb-c
Much as I find the 3.5mm jack in no need to be replaced with anything else, I still do see the improvement the whole deal gets from the USB-C port replacing microUSB. Over the years, death to three of my phones came in the form of the USB socket countersunk by countless cable insertions and the mechanical wear. I do hope the new USB-C socket is designed and built to withstand more.
