I've found this (https://www.amazon.com/s/ref=sr_nr_p_72_...) and this (http://www.etradesupply.com/samsung-gala...). I'm still not sure as to how to safely remove the bottom part of the charging cable/port (where the micro usb plugs into the device). It's underneath part of the shell housing that seems particularly tricky to get to. Anyone else have any luck with it?
