The Spot is nearer to the both 9.88 wh on the label
Thanks for your help

Yes the original battery that was packed with my phone. The metallic cover is the original S4 Cover, that should be the same that was tested in q&a.
Ok I tried with the s-view cover and without any case. I found a spot without case and used a ruler to get the spot. After put ting the spot sticker directly on the battery there is no spot anymore. After detaching the sticker there is the spot.
So whats next? I contact the support or do you have any clue to get a fix for that?
Thanks for your help

My battery says
Cell Made in Korea, Assembled in Vietnam that differs from the battery on the picture from here

Here mine Picture

Even if it fails with both original covers and would work without any cover the ring has to be replaced or should one leave any cover off? But I'll give even that a try

The nexus 5 was someone else device, ok then I will have to contact the support again. Later today I will try it with s view cover on, or doesn't that matter?

Hi,
there is no reaction of the ring at all, even not on the nexus 5. Tried four ways holding the ring 0° 45° 90° 135° moved mm for mm slowly about 1mm/s. Are you sure the inlays are not just a peace of varnish?

Hi,
I did receive my ring the last days and tried to use it with my S4, nothing works. The small sticker with the nfctack showed me my spot. The ring doesn't work there. Do I have to do anything? Do I have to remove a sticker on the ring or anything else?
I ordered an alpha ring in black on black and I got this, please check and tell me what I'm doing wrong. Thanks
