Samsung Fast Wireless Charging Stand Pauses!

Mod Note, please do not post your email address on this public forum
 
Invariably when I plug in my S8+ or Samsung Galaxy Book I get the message to plug in my fast charger that came with the device. Problem is I'm using the fast charger that came with the device.
 
My Samsung model EP-PN920 wireless charger (the flat hockey puck looking thing) worked flawlessly for two years, reliably charging my Samsung Note 5 phone from Jan, 2016 to Jan, 2018. Then I began experiencing the blinking blue light and the cessation of charging. I thought that maybe the problem was caused by the Jan 1, 2018 software update, so I began charging the phone via USB, and waited for the next update….which arrived, but the problem remained. I removed the fairly thick rubber cover I use (the liner from an OtterBox Commuter Cell Phone Case) from the phone, and the wireless charging problem went away. Hmmm, seems like there’s something impeding the current between the charger and the phone. What could have changed, I wondered. Unable to think of anything else, and doubting it would make a difference, I used a damp cloth to wipe the top of the charger, dried it, and waited for about 15 minutes. Then I put the rubber Otter case liner back on the phone, put the phone on the charger, and it’s worked great ever since! (I guess there must have been two years’ worth of dust on the charger, though the shiny white surface hid it well….ouch, I’m a embarrassingly lousy housekeeper, lol.)
 
I believe that the wireless charger receiver attached to the battery could be at fault for this issue, if you can plug in a wired cable and it works fine. If you can barely do both it's a software issue. Honestly, I believe it's both but it depends on the model of Samsung and your service provider. I had a note 5(by AT&T) and it was the the wireless reciever module. I got a Note 8 and it was a software issue(after upgrading to Verizon).

I have had the same issue and was ready to throw the wireless pad in the trash, but I tried to make it work one more time and BAM! I figured it out!!! I picked up the pad while having my phone upright in my hand. I put the pad up against the phone while holding them both upright. The phone started charging...and didn't pause. I held it for a few minutes that way, trying to think of a way to charge it upright. I couldn't figure out a way to do it, so I just laid it down...and it kept charging. If you keep them pressed together then I lay it onto a flat surface keeping them pressed together, it will keep charging without pausing. I have done this for several days and its charged no problem. How BIZARRE is that? But it worked!!!
 
I had this issue with multiple different fast chargers. I found the issue was actually the magnetic piece I had on the back of my phone. I use it for my phone cradle in my car. Once I removed that I stopped having these issues. Hope this helps.
 
So we just went with the Note 9 and added the Samsung convertible wireless charger (model #EP-PG950). When it is in the 'up' position it does the charger starts to work and then it pauses and stops charging. When it is laying flat, it works awesome. Why would it pause when in the 'up' position? Maybe the Note 9 is just too tall? I don't know, but I thought I would throw my problem out there to see if anyone else has this issue.
