Cool [Q] USB Port - bad solder, or just needs a clean?

I've inherited an S3 with a broken USB port. It used to work intermittently, but has now stopped working altogether. I've added a wireless charging thing, so it's usable.

I had a quick look inside today, to see if there was anything obviously wrong.

I'm not sure if those two soldered connections on the end look a bit dodgy, so I thought I'd ask on here if it looks like I'm going to need to reflow it, or if you think the connection looks fine and just needs a good clean?

Obviously, I don't want to start soldering things if it's unnecessary.
