I really miss the days phones came with covers for the USB ports. They were annoying as hell due to my lack of finger nails, but damn the port stayed spotless. Every phone I've had lately the usb port gets so full of dust and crap chargers stopped working properly unless I fucked around and balanced it just perfectly.
You can buy female dust covers on Amazon. I haven't really had issues. My biggest complaint was how susceptible USB micro was to breaking, but no problems with USB Type-C phones.
If moisture or debris is detected in your USB port, a notification will be sent to you and accessories will not function."
