WIKI - NFC phone performance

Does anybody own a Fairphone 4 who could comment on the thing’s performances with small difficult glassies? This thing is right up my alley, especially with /e/ OS installed, and I would buy one sight unseen and take a chance on NFC performances, were it not for those worrying reports.

I tried sharing my contact information with someone who had a Galaxy Note 20 today: with a thick case, the damn thing wouldn’t read my flexNT nor my Apex Mega. Without the case, it could only read the Mega - and not very easily at that.

Because I knew the guy well, I asked him if I could try to find the sweet spot with his phone myself. It took me a while to find the mega, and there was no way I could get it to read the flexNT in any position or angle; That’s kind of a first: I hadn’t found a celllphone or reader that failed to read that implant before.

I don’t know if the guy’s phone was faulty or something. But if it wasn’t, I’d say the Galaxy Notes 20 hits new lows in NFC performances.

That’s strange. I don’t have the phone anymore, but even with a thick case I was getting easy reads from my glassies. It was even to the point where I kept accidentally scanning them by holding my phone the wrong way.

Did he maybe have the Note 20 ultra? I was using the standard Note 20. Maybe different regions have different antennas? I really don’t know what the issue would have been.

Got a Pixel 6 a few months back and it seems to have the same antenna orientations darthdomo pictured in Oct '21 for the Pixel 6 Pro

I had the Note 20 Ultra and couldn’t read my glassies with the case, without though, I was able to pick them up pretty quick.

My company gave me an iPhone SE and it works well with my xSIID and NExT without the OtterBox. With the OtterBox, it would light up the xSIID but not get a read. I also had to install NFCTools for it to start scanning for tags, there’s no NFC settings, and it doesn’t auto scan without an app. That sucks, because once you scan the xSIID, it stops scanning and the LED doesn’t light up again. I like my android that scans constantly so I can show off the LED better :joy:

I have a Google Pixel 5 and an LG V30, while both work great reading my chip without cases (Spigen Tough and Rugged Armor). Once the cases are on, it’ll light up the LED, but I can’t get them to actually read the implant and perform the function assigned, ie. open a web page. When I take them off, they immediately read the implant.

a couple of options for you to consider
