A:AnswerIt works great with the S9+! I'm so glad I made this purchase! I got the OtterBox Defender case with my phone immediately to protect my investment as I had it on my last phone I had for 4 years (which still looks like brand new out of the OtterBox case!) which is the best insurance you can get for your phone in my opinion. The charger works perfectly through the Defender case. I'm very happy with this charger and would buy it again! Hope this helps!
A:AnswerI am assuming you mean the S7? Yes, this charger is actually an older version, so it is meant for the S7, S8. There is a newer version for 2018, S9. The new S9s have a different connector than the S7, S8s. But since this is wireless, it works with both.
It is more difficult to get the phone to charge standing up, it does not always fully connect, so you may think it is charging, but it is not. We were told at the store that the reason could be our cases. I have an Otterbox & my husband has a much thinner case. The charger that lets you lay the phone on top of it is more reliable. I have stopped using this charger.
A:AnswerThis is the great thing about this charger i have been able to keep my cases on and still be able to have the charger work unlike some of the others and some of my cases are layered and quite thick. I am not sure about the magnet im not a big fan of magnets and electronics they sometimes don't mix lol so I can't tell you much on that.
