It turns out I was not crazy...
When the Fold 4 arrived, I pulled off the cover of my S20 to pop the SIM card and found this... So my old phone was living on borrowed time... YIKES!!! Anyway going to see if I can get it repair if not to expensive so my son can use it. But I am going to not carry my new baby in shirt pocket where it can fall out as it appears cases can only protect so much...
BTW the Fold 4 is simply amazing... Loving it so far. Biggest challenge is going to be getting a good case for it as the phone design seriously hampers case design and functionality. TRying to avoid paying $100+ for a Spigen which appears to break as easily as some of the cheaper cases.
