By default, this phone model does not support wireless charging, but it can be enabled using an add-on module.
I ordered a Wireless Charging Receiver like it is mentioned here. You simply need to insert the module between the battery and the back cover, and connect the Micro USB port.
Unfortunately, if you place the module on the default position, it covers almost the whole battery, so NFC does not work any more afterwards.
After some tests, I found out there is a workaround to keep NFC enabled also. The trick is to place the model about 1 cm below its default position. Now the black end line with the Micro USB connector is too long, but you can fold it carefully so it fits under the cover.
If you test NFC now e.g. with an NFC hardware button, you should have a good NFC signal if you place the button near the „Samsung“ sign at the back cover.
