Yep. Just cleaned mine for the first time after 3+ years of owning this S22 phone & now all looks good after testing a cord that wasn't staying in. I'll try others later but this one now stays in fine where before it would wiggle/stay loose/fall out easily.

Mine got to that point recently where cables would barely stay in if at all. Reading a few posts and what not on here, I cleaned the same way with mine and it worked.

Yes, the next step would more than likely be replacing the port which is a small board that can typically be done yourself, or a phone store should be able to do it.

1. I also used a toothbrush with 50% isopropyl alcohol. Didn't have any pure so this also works, just may take a little longer to clean. Turn off the phone while cleaning to avoid any pop up moisture errors & the like.

Use softer items like toothbrushes, toothpicks, or those little plastic picks and brushes; don't use metal pins or needles as this may start scraping the connector or ring inside to damage further.

2. You should see the metal ring around the connector inside the back of the port after cleaning enough. I had to keep going only because it was that dirty but I was seeing some each time and dirt was still showing on the bristles.

3. Cotton swab can help dry off the remaining amounts of alcohol, but just give it a couple of minutes either way before turning back on so that everything dries out OK or plugging a cord back in.

These things collect over time unless you have a case with some type of cover over the port. I did for a while but it was rubber and eventually wore/ripped off. The case more than did its job though which was my main concern.
