I see. I'm curious, what difference or differences specifically? Anything specific other than possible changes in the cable?
Besides what have been mentioned above, I have also seen reports of early MMCX socket failure and driver imbalance. There is even a silly case of mismatch driver serial (the number on the driver doesn't match the one on the certificate) that make me wonder what the QC personal was doing when (s)he was doing the final checkup. These would have been very unusual a few years earlier, though I won't rule out maybe they are all isolated cases.
