NFC - Unable to connect to printer
Just installed my Mk4 to Mk4S upgrade kit yesterday.
I thought I'd try the NFC feature to send the wi-fi settings from the Prusa app.
I have a Samsung Galaxy S24+.
When I try and connect, I get an error on the phone - Unable to connect. NFC on the phone is enabled.
I don't believe I have any installation issues. I have checked the antenna lead connections and they look ok.
Every now and then I will get a new tag collected message on the phone, identifying something like "PRUSA3DMK4S" so I expect this means that the NFC function itself works.
Has anyone else experienced similar issues?

I'm having the Very same issue. Using Samsung S24, MK4S fw 6.1.3.
RE: NFC - Unable to connect to printer
Prusa has sent me another coil antenna to try and it is also unable to connect.
Holly K, on the basis that you are also experiencing this issue with a Samsung S24, this would indicate perhaps a compatibility issue with the Android firmware that Samsung is using.

RE: NFC - Unable to connect to printer
I installed my upgrade yesterday and tried the NFC connection today. Several attempts failed but then I tried other orientations of my phone. At some point, the phone (SAMSUNG S10+) could connect. I suspect the antenna/HF cable combination provides a weak signal.
RE: NFC - Unable to connect to printer
I just got my assembled MK4S today and have a Samsung S24 Ultra, and NFC just wouldn't work. I tried various orientations, nothing. Had to input wifi manually of course. Minor issue but... a bummer.
RE: NFC - Unable to connect to printer
I tried the Wi-Fi setting via NFC a Samsung S24+ and doesn't work. However, an iPhone was immediately done and an older Samsung S20+ also worked after some rotation. So this is not a NFC hardware error on MK4S, but possibly some compatibility problem with the newer Android, or maybe a weaker signal of S24+ NFC.

Even with an iPhone, and it does work, but its quite slow, so be patient. Its not like buying groceries with your ApplePay, probably took 20+ seconds.
RE: NFC - Unable to connect to printer
I have a S23 and it works just fine for me.

Failed with a Samsung Note20 5G. Rechecked cable connected etc.
RE: NFC - Unable to connect to printer
After Upgraded from MK4 to MK4S i did a restart and did all checks new AND i tried to send WIFI Configuration over NFC.
But it didnt work here too. 🙁
I checked the NFC cable on both side, but its correct connected.
Im using an Samsung S24 too. :-/
RE: NFC - Unable to connect to printer
The good news is, even if it doesn't work there are workarounds, and its something you only use once. (unless they add RFID to filaments, but not holding my breath)
RE: NFC - Unable to connect to printer
Just received my new MK4S and could not use NFC to setup the Wi-Fi connection. I too am using a Samsung Galaxy S24+. I had to set it up from the printer control panel. Definitely a first world problem, but a minor annoyance.
RE: NFC - Unable to connect to printer
I have the same Problem with an iPhone 13pro, no connection over NFC.
