Oh, dear. Welcome to my club. My first S8+ worked fine for a couple of days then quit charging. I did everything Samsung support suggested, then they gave up and I took it back to Best Buy and they exchanged it for a new one. This one worked fine for about a week, then started behaving erratically when I attempted to charge. Sometimes it would recognize the charger, say it was charging, but my phone would actually lose charge while sitting on the charger unused. Sometimes it wouldn't recognize the charger, but when an incoming call canned in, it would start "charging" but still lose charge. I did everything Samsung tech support asked, even tried two different chargers, with no result. Samsung asked me to send it in for repair and I was waiting to see if Oreo fixed it (it didn't) so now not sure what to do. Don't really want to be without my phone for 2-3 weeks...

try going to settings -> device maintenance -> battery. Then click the 3 little dots on the top right hand corner, then click Advanced settings. Make sure the bottom setting ("Fast Wireless charging") is toggled to the right. If it's already toggled to the right, try toggling it to the left. If this fixes it, then go back to the setting and put it back to the right (the toggle to the right means that "fast wireless charging" is enabled; the toggle to the left means that it is disabled)

I hate to bring up something that is probably already accounted for, but some phone cases will interfere with wireless charging.
