Thank you! I updated the post title to TENTATIVELY FIXED. Your comment suggested to me that I was probably safe having a go with cleaning the socket myself (versus seeking out some mini vacuum). I used a toothpick-like tool - it was a poker to get a phone sim card deck to pop out. Using the tool and gravity I got a very small amount of lint out. This has notably improved the issue; I only experienced it once afterwards versus multiple times. But I’d like to test it out some more when I have more time, hence the tentative. Thanks again!!
