I am developing an hce app. The app is on my lg g2 not running and I don't know why. Could you please install the enclosed app and test it with a smartcard reader. You have to send the command apdu 00A4040007F001020304050600 to the phone with nfc enabled. The response should be 9000 if everything works. I am only getting 6f7 rom the reader wich is a failure. If you have another hce payment app installed you would have to set carde as default in the tapp&pay settings. With my nexus 5 I could get the 9000. Only my lg g2 seems to be bugy. Thank you in advance!
