Super simple to repair, if you have a small phillips screwdriver and about 30 seconds, the part is a couple dollars on Amazon http://www.amazon.com/Samsung-Galaxy-Replacement-Port-Cover/dp/B00L4RYCMU/ref=sr_1_1?ie=UTF8&qid=142...
and the repair video is here
Samsung wants me to send it in for repair and Verizon wants to send me a refurbished phone instead of just replacing the cover. They have them on eBay, but they make it out to be extremely hard to change them. There's an IFixIt store near me, they want $35 to change it. Has anyone changed one? Is it really that hard? I don't want to damage my phone.
It's not difficult if one has the correct tools and skills working in a very small space. However both Samsung and Verizon have stated it will void the warranty if not performed by their own repair people.
Also without cover in place a homeowner's insurance policy with rider will not cover water damage replacement. May be the same for Asurion's and Total protection Plan.
