Haven't voted yet because I think we should wait and see if the alpha solves it for everyone. Two rings that does not register is not much better than one imho. :|

Did you try to roll it over the sweet spot and tryed to orient the ring differently. the problem is probably the curve of the ring, so if you have a smaller ring size, the tag will be less "flat" and so less parallel to the reader. (hope this makes sense ;) )

I have tested the ring on a Sony xperia tablet Z(works fine) Samsung galaxy S4 (does not work) Samsung Galaxy S4 active (works, but weak signal). I use stuff like my nfc enabled headphones with no problem on all devices.
My ring is actually so big I think I have a bigger size than I ordered and I have used it more as a thumb ring. I tried to bend the small bonus tag included in the shipment, and the G2 was still able to read it. So it must be the coating on the ring or something I guess.
I ordered the carbon inlay so this is basically a test ring anyway. I am considering a alpha type ring if it works, and would love to see some feedback on this.

My personal conclusion is that the normal ring does not work with the G2. I am 100% sure, and have tested it over some days now. However that just is my ring on my phone, I would like to hear if others have other experiences. And especially if the Alpha ring actually works with the G2.

My normal NFC ring does not register on my LG G2, Both of the xtra NFC tags registers fine.

Curious to hear if anyone is able to use the NFC ring with the G2.

The Ring Works fine on my Sony Tablet Z.

I can confirm this as well, My normal Ring does not register on my wifes S4 (or my LG G2). But registers fine on my Tablet Z.

Ordered a normal titanium with Grey and Black carbon. I guess that means black and white and no survey? Transparent would be nicer than white IMHO. But I guess I can use that as my 'private part' for now.
Sorry if I missed some info but why not just ship the fail-carbon with vouchers for a new cf 2.0 nfc ring in the future?
