Case with Covered USB Port?

Has anyone found a case for the Moto X Pure (Style) that has a covered USB port?

I bring my phone into the shower with me to listen to music, and I want to do whatever I can to prevent water from getting into the USB port. I know that the phone is somewhat water-repellent with its coating, but I'm guessing that frequent exposure to steam & water droplets will eventually corrode the MicroUSB port.

Notification LED covered by glass frame coating?

(Sorry for the weird title, couldn't think of a better one)
I recently bought a used Note 3 and after a few days I noticed the notification LED wasn't working. I didn't really mind and forgot about it, until one night I connected the device to the charger and I saw the LED shimmer through between the screen glass and the bezel.
I looked closer at it the next day and noticed that there was simply no hole in the coating like there is for the sensors and front camera. I took the device apart and used a needle to scratch the paint coating away where the LED is and now it looks exactly like it should.
Now I wonder if this is some weird production fault, maybe there are more people who have this problem and maybe didn't even notice their device has a LED (I actually only found out after I saw the LED settings in CM12). If so, I could make a tutorial with pictures on how to do this fix, it's pretty easy and safe.
