So is your Huawei watch still stock 1.5, or did you install the 2.0 preview?
If you installed the 2.0 preview, is NFC enabled for Android/Samsung pay?
I am stock. I just purchased it in January thinking I would get the update soon. I thought about doing the update to the preview but did not because I kept on thinking the update was just around the corner.
NFC is definitely not part of the 2.0 preview. I don't think it is going to be available in the actual release either although I am hoping it is. I have heard that there is a chip but the rest of the hardware needed for Android Pay is not in the watch. But who knows.
