When I bought my Samsung Note 8 phone, I also bought the flat fast charger from Samsung along with the Samsung phone case. Was disappointed to find out the Samsung phone case does not work well with the charger. Considering I bought all the Samsung name brands thought they would work well together. But, in order to charge my phone with the flat phone charger I have to take the phone out of the phone case other wise it will not charge. Samsung should of tested this with their cases before offering it for sale.
