I experienced this exact problem when I used the OtterBox case with my Note 8. When I bought the S9+, OtterBox was not even an option i considered this time around.Well add one more to your list of phone that will not work with the wireless charging pads galaxy note 9 . I got the phone on Friday it would charge the phone if you lay the phone on it side but not up right on the pad
If a metal back is used, it must have at least a 'window' of non metallic material to work,located near the qi coil, due to magnetic flux preventing charging through an all metal (aluminum) back .I gave up wireless charging a while ago, because of the heat the charger throws up to the phone, but I was charging through a Defender for about 4 years. I could even lift the phones up about 1/4" and they'd still charge. (And it's only the distance that determines it - the materials used are transparent to the frequencies used in wireless charging.)
I hear you, and wish it was possible. I'd rather have an S5 type back I can take off, a user swappable battery and a firm SD card holder and sim, not this 'I hope I don't break it' slide out tray.And since a Qi coil is about 2" in diameter, that's a serious hole. I'd rather have a solid metal back.
