As stated above, my S8+ as of last night will no longer fast charge. Everything was working accordingly and I recieved a notification to update my firmware, so I just let my phone update before bed. I woke up to this issue. My phone has been meticulously taken care of, I just find it odd that I update my phone and literally the next day I'm having this issue. I'm curious if anybody else has had this problem or knows how to troubleshoot it. Just to save everyone time, I've turned on fast charging, tried charging it in Safe Mode, I've reset my phone to factory settings as well. Called Samsung support for them to tell me that the update may have corrupted my phone and I'm left without a phone for 7-12 days and I have to pay shipping
