This is not my experience. My phone reported fast charging connected to a QC3, QC2, USB-PD and even plain old 2A USB charger. The only time it didn't was when attached to a 1A or less charger.

I haven't gotten to do any extended testing. I will do that testing yet. I will try some testing taking the phone from 20-50% with the QC2, Samsung and USB-PD chargers. That'll take some time to do and I won't be able to do it until likely tomorrow some time.

OK.. Here's the analysis. Used an inline USB-C power meter. Based on this, it appears QC2 is still what's implemented: All tests performed with battery between 19-21% QC3.0 Charger: With Screen on -- Charging at 5V and 1.25A (6.25W) With Screen off -- Charging at 9V...

It seems to me that anytime it can grab over 1A@5V the S8 is reporting quick charging. I'll do some analysis late tonight and post the results.

Precisely.

Just a note the stock charger reads: OUTPUT: 5V @ 2A or 9V @ 1.67A So it appears with the stock charger it can charge at up to 15W. Since the QC2/3 max current is 18W (and 4 is 28W) this is firmly in the QC2/3 territory. At least it is better than the 10W max of QC1.

Well, with the battery at 40%, exactly the same amount of time. I also tried a QC2.0 charger, and the time was again, exactly the same. In all cases the screen showed "fast charging" Edited to add: I have a USB-C pass-thru power monitor coming from Amazon on Sunday. I'll take all the...

When connected to a QC3.0 charger with the included Samsung cable and the battery at 40%, the S8 is drawing 1A but I haven't found an app that shows the voltage it is drawing so for all I know it is drawing 18V at 1A, which would be QC3, or 1A at 5V which wouldn't even be QC1. That being said...
