I have a USB C based DAC. I just tried plugging my new S20 FE into it via a USB-C to USB-C, cable, it did nothing. Tried it via an OTG cable + USB A to C cable, and it was finally detected.
So it was the cable, right? Well, no, cause that cable worked on an S20 FE my sister bought a week before mine, and it worked with both an A50, an old Motorola phone I have, and an PC.
I have multiple USB-C to USB-C cables, none worked with my S20, but all worked with my sisters. Should I RMA the phone?
Solved! Go to Solution.
Thanks, this actually helped me diagnose the issue.
Samsung seems to have REALLY dropped the bar with their USB-C implementation. The DAC works, but is both side AND orientation aware, like an USB-A to Micro-B cable. Phone works in literally only one of the 4 ways the cable can be plugged in.
Tested again on my sisters phone, seems I just got "lucky" the first time I plugged it in her phone, it act exactly the same, only one side out of 4 works.
Tested to see if my PC or older phone do this too, and they dont. Old phone is USB 2, while PC is 3.2 (10GBS). I dont get this, why the **bleep** my old Motorola is doing this better than a flagship. I would get if it was an USB 3 issue, but my PC had no issue with it's Type-C USB 3 port. And for some reason, using an OTG with a normal A to C cable completely removes the issue.
