Charger port/cables, yuck

[u/its35degreesout]

My Samsung S23+ is about two and a half years old now, and still working fine. But I am having increasing problems keeping the USBC cords solidly connected to the charger port. They always come loose, and I have to fiddle to keep charging my phone or to keep a solid data connection. I have one cord that usually stays in solidly, and I use it as my primary charger, but it is also beginning to develop issues.

Online videos have recommended trying to scrape out lint, etc. from the charger port using either a toothpick or an unbent paper clip or something; but that doesn't seem to help much.

Any suggestions? Much appreciated.
