First: I just noticed a very faint buzzing, even a little clicking on my Samsung quick charger. I have to get close to hear it so I’m not sure how long it’s been going on. Search pulls up a lot, but what is different from other posts is that the sound stops when something is plugged in and other people seem to have the opposite issue.
Also: I know Qualcomm made the technology and multiple companies adopted it, does this mean I don’t have to buy a Samsung branded charger? And is there an easy way to tell which of the 5 or 6 generations without searching model numbers?
