I had someone insert a non-Samsung USB-C into the port of a Galaxy S10, both bought in Thailand. It doesn’t fit. It can only be inserted 2mm, then it hits resistance and cannot be inserted the last 1mm, and there is no contact. Same as my problem.
It’s amazing how everybody - not only on this forum - told me this must be my fault, my phone must have a problem, my port must be damaged or dirty, my cable must be fake or not good.
I am quite capable of realizing that this plug is not made for this port.
Samsung uses proprietary ports and erroneously calls them USB-C. Once I figured this out, their call center agents admitted it.
BTW It’s equally amazing how everybody insists that USB-C is a “global standard” when a short googling tells me it’s not, it’s a mess.
Google also mentions that, in 2016/17, Samsung did plan proprietary ports. Before this, the Galaxy S5 did have proprietary cables and ports (not USB-C).
Where does this trust in Samsung and HiTech come from?
