Wanted to update my previous comment stating the ulefone armoire 3 and 4 worked and the best location and orientation is having the chip vertical up and below the camera by about an inch. It seems all ulefone’s I’ve experienced so far read best at the top 1/4 of the phone. I was also going to ask if anyone with a pixel 4a could chime in as I’m thinking about upgrading my phone as it’s quite a bit old now.
I’ve updated my comment to follow your spelling conventions now onto hoping someone with the phone I’m looking at also has an implant and posts that it works. Otherwise this dude is masking up and bribing an att employee so I can run around the store testing every phone and taking notes like a madman for the forum
I get best results with my Samsung S9 when lining the chip up with these two lines on the back of the phone - conveniently, that lets you use your index metacarpal against the edge of the device as a reference if you’ve got the chip nearby.
Implante next en izquierda y spark 2 en derecha, los dos con informacion de contacto y he aprendido una cosa, no se el motivo pero es asi, si escaneo con samsung, spark;si es huawei con next, es dificil el next con samsung, sera por nfc2 y spark tipo4?
I use to keep my iPhone X naked but recently added a leather case. Makes the orientation I have to read my xNT completely different. Possibly unrelated but
Sony Xperia XA1 Plus works perfectly with the HF side of the NExT.
While I tend to center the NFC Forum logo for regular tags, the best performance with x-series implants seem to be achieved if you go above the NFC Forum logo, around the same level as the LED.
You’ll want to make sure that x-series chip will end up being vertical to ensure good coupling, which means that it will look something like this:
You can add the Google Pixel 4a to the list too, it reads very well. The best orientation I’ve found is the tag vertical, just below the finger print reader. I get super consistent reads and writes with a thicker case, and it even lights my xSIID super bright.
At least with a spigen Tough Armor case, this was the only orientation I found that really works, but it’s effective.
Huawei P20 works pretty well with x-series from the left-hand-side. You hook your fingers around the top, so the joint between your fingers and palm is nestled in the corner, and lay your thumb against the back of the phone. I usually get a read within a second.
