Galaxy S3
-
Works with a tiny little temperamental sweet spot near the volume control on the back cover. Seems to glitch a lot, but probably more app than phone-ring compatibility.

Hi @Josef
Have you got a Classic/Normal ring? (The thinner one.)
The S3 is one of the more difficult phones to use with the NFC Ring due to Samsung's design/implementation of NFC. You'd get the same 'glitching' if you just try to read the ring with a different program I suspect.
Do you use the unlock ok with the ring?
-
I found that my sweet spot on my S3 was right beside the "G" in the Samsung logo on the back, vertically parallel to the speaker. Basically if you drew imaginary lines from the speaker and "G", where those lines intersect is where my sweet spot is. I no longer need a sticker to remind me of that location because it's become muscle memory for me.

Hello,
as i know, Galaxy S3 have NFC antenna inside the battery. And in battery area working perfectly with all of my NFC tags..
Sadly, i don't have my NFC Rings yet, because i'm waiting for delayed "Stealth Bombers". (Two classic and one Alpha)
So... When they arrive, i'll let you know where is a sweet spot on 7000mAh ZeroLemon batteries :)
-
I managed to test an S3 today with a flip case. The S3 was brand new but the flip case left me unable to trigger a read with either an Alpha or a Classic ring. Very disappointing! Without the case was fine.

Hello,
my Rings arrived today (not the Stealth Bomber, but normal Rings)... Two normal ones and one Alpha ring..
They work well with the original Samsung battery, but they need to be placed precisely about 1,5 cm under the Samsung logo (Both normal and Alpha).I have these problems with the "ZeroLemon NFC Enabled 7000mAh" battery:
-
I can't find any sweet spots with the cover on - Alpha Ring works everytime at different places, but not twice at the same one... I have succeeded with normal ring only once.
-
Without the cover the sweet spot is directly on both sides of the battery (the Battery has a visible large antenna, which is from side to side in the size of a standart Samsung Battery).
Other tags (Samsung TecTiles, some no-name Mifare tags from eBay, even the Credit Card) and spare tags from this package are readable very well even with some money under the battery cover... But Rings won't work...
-

@ententeak hi, if the Alpha works then it's your method that's not right - try moving the Alpha ring through the sweet spot that you find instead of just holding it to that spot, vary how fast you do that and the orientation of the ring while you do it.
The rings will behave differently to a standard style tag, this is expected due to their construction and metal composition so don't try to use the ring as you would a standard tag. Be slow and methodical in your method, and practice will make it easier.
-
The Rings itself are very comfortable, but their usability isn't...
I just want grab my phone to unlock
I'm using "NFC LockScreenOff Enabler" Xposed module to unlock my phone.And i know, that these tags working differently than standart tags, but my other tags are working even 1cm far from phone independently from "Sweet Spot"... just somewhere around the Antena...
These rings are working in one of fifty attempts... (without battery cover in 1 of 10) mostly from "succesfull" attempts i've get "NFC lost" toast message (Alpha work better - about 1 of 30 with cover)
and this is really different from what i've expected and i'm little dissappointed...
it's really uncomfortable to riding with the ring around back of my phone, when its faster to unlock by passcode...I'll try it yet with my Nephew's Nexus 7 if the ring works correctly and will see, what to do next... Maybe it's really only ZL-Battery issue...
Edit: without battery cover it took 5 second to recognise the standart ring holding still aligned with antena...
and with that, i've found one funny thing with this Xposed Module... it unlock even with "Tag Lost" message, because it read TAG ID to authorise instead of written data's...

Hi @ententeak. There is no "but" when you're comparing other tags to the ring, you need to forget all that and concentrate on refining your method of use.
Try this:With ring completely away from phone and phone locked, sweep finger towards sweet spot slowly and through until it triggers, then remove ring completely from phone.
If the ring remains partially within the trigger zone on the phone after a fail it wont always pick up again, you need to pull it entirely away and go again.
Don't be deterred by the seeming awkwardness of this initial exaggerated movement for unlock, refine it until it works, until you trigger the unlock as often as possible, then refine your method until it's natural.
First you need to train yourself to always hit that sweet spot the right way though! It's like learning any new thing, don't underestimate the amount of effort that can take initially.-you're right about the Xposed module using UID for unlock, it can do this because it has lower level access than the Unlock App for NFC Ring does. So even when the read isn't quite right the phone can still grab the UID and perform the unlock - it makes it a little less hit and miss for some phones.

Having the exact same trouble with an S4 with the giant Zerolemon battery.
Lokki, I don't think you've seen one of these - the NFC antenna on the back is absolutely HUGE! It's about 3" square (7 cm square, for the metric-minded) and swiping vertically, horizontally, with the "rolling" swipe - doesn't matter. This ring does NOT respond. No, not even with a completely "away" swipe like you're describing.
I'm thinking of just putting a cheap NFC sticker on my belt or something, and swiping THAT instead. The standard 203 chips and even Micom chips work every time, even with the case on. Not as elegant as The Ring, but at least it WORKS.
Unless there's some magic fix for this, I'll have to call it a day and return these.

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.
-
i dont think it help...
Here is a picture of the battery with almost visible antenna, compared to size of USB and NFC Ring
and here is one picture with the silicone battery cover...
-
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.
