I have a Spigen fast wireless charger that is Qi certified. I have had it for over 2 years now. I used it with no problems with my former S10e and current S20-5g. Recently, I noticed the S20 will start fast charging, ("Fast Wireless Charging Started") then will stop and the system will say the charger isn't compatible and will drop to the slow charging rate.
I've had this S20 for a year now and have been using this same charger without issues until recently.
A colleague has a Samsung branded fast wireless charger at work -- (model EP-P2400) and when I put my S20 on that it immediately went to fast charging and stayed.
I pulled out my old S10e and put it on my Spigen charger -- bingo, it immediately goes to fast wireless charging and stays that way.
Why does my old S10e have no problem with the Spigen but my S20 does?
