NFC has stopped working on my Note 4 (N910G). As I understand it, the NFC antenna is embedded in the battery - it seems to be, I can see an antenna.
I am using an Anker replacement battery, but NFC has worked in the past with this battery.
Is there a way that I can check the antenna is working - that it is picking up a response? Is there a way to get a raw readout of what the NFC chip is seeing?
