I'm not sure if there is a limited use on the nfc unlock app, but I have used my log in to verify my previous phone (and my couple's). But we now have new phones and can not use the same login to verify the app.

Can someone walk me through the procedure to resolve this issue please? Many thanks!

I agree that the difference between the two uses is odd.

There is no improvement after waiting ten seconds. I completed a factory reset of the device to remove any other factors but the issue persists.

Regardless, the ring is incompatible with my current phone case. I shall leave the ring aside until I get the Note 4 at the end of the month. Thanks for the help!

Ring is enabled, and the key has not been over-written. I should also clarify that the detection of the ring when using the app is almost 100%, but when attempting to unlock the phone, it is only successful approximately ~15-20% of the time.

Hello,

I received my NFC ring today and had no problem registering the ring on the NFC unlock app. (Disabled native android lockscreen, created PIN for app, no 2-step verification on google, etc.) However, the app fails to detect the ring when I attempt to unlock my phone, despite being able to successfully detect the ring via the app on multiple attempts. Any suggestions?

Edit: Device is a Samsung i9300 and I've previously found the 'sweet spot'.
