Lokki, I don't think you've seen one of these - the NFC antenna on the back is absolutely HUGE!
Ironically that's probably the problem with these phones. It is a big mismatch in size with the ring circuit, and that makes the induction harder. Smaller is better when it comes to a phone antenna mating with the ring.

@shama is right on this one @ententeak and @8writer. It's the mismatch between the size of the ring antenna and the phone antenna, being huge is what causes the issue. It causes the sweet spot where the ring will read to be extremely small and rather weak.
If you do get to the point where you're sick of trying the ring with your phone just take a moment and consider how much longer you'll have that phone. Most people are on a two year cycle with their phones before they upgrade, and the odds are extremely good that the next phone you get will work better than perfectly with the rings.
Just food for thought there.
In the meantime there are plenty of other things you can also do with the ring like arduino based projects or your house locks with a door lock or two from Samsung.

Yes.. the problem is in Antenna... I've tried my rings on NFC enabled phones of my coworkers and they worked very well...
like with my S3 with original battery... -
It might also be that the nfc antenna in the phone isn't contacting well. Since its in the battery you might be able to give it a non chemical polish with a pen eraser.

What would happen if you were to make the cover thinner where the ring works on the battery?
It would have the dual function of guiding the ring in physically and making the gap between the ring and the phone nfc antenna smaller. -
i have that idea too, but i dont want to have a hole in the cover... :)
-
Fair call! Still, it's an option though, perhaps with a spare case.

You probably already have a couple of holes in the cover! For the camera/flash, for the buttons ...

@shama good point, but these are prefab and my skills of handworking are realy poor :D
