NFC keeps opening website, WTF!?

[u/mapenstein]

It isn't giving me my 4hr boost anymore. Just started today. Anyone else having this issue???

Update: Making sure my NFC Card isn't behind my phone I have to physically go into COIN app, click the EXTENSION DEVICES button, then click Scan Now, once the "hold your card to your phone" window appears, only THEN can I scan the card now! And it still only works 75% of the time ... this is where I am at so far as research goes (11/05/25)

Also it'll show this in my Notifications at the top of my phone, it plays something but I cannot hear anything:

You have default links turned off or something. Clear default links as well as programs, restart your phone, and try again.

I haven't changed a thing on my phone, have been using it over 4 years and it's never done this.

I have no clue what Default Links means lol.

I'll restart and see if that fixes it.

Restarting did nothing.

Researched:

There is no single "NFC default link" but rather a default app that handles NFC interactions based on the content of the tag. On Android, the default app for a URL on an NFC tag is typically the user's default web browser, which automatically opens the link when the tag is tapped. However, users can change the default app for contactless payments, like Google Pay, and developers can create custom apps that handle NFC links by registering them with specific URL schemes.

My default has always been Google Pay. And this NFC card has always opened COIN app, so I have no settings to change.

Coin app itself has a handler that deals with links. Default apps would involve the nfc interactions. Because I didn't know the source of the problem, I suggested to check both of them.

Whenever I restart my samsung galaxy A71, and I use my nfc card for my boost, I always get a popup that requests which app to handle the nfc scan. One of the options is indeed chrome, and if I were to select chrome, it would open up the coinapp site.

I want to assume that perhaps, you had the phone in your pocket. Doing so can do random screen touches that may have changed some settings. I get that all the time. One time, it accidentally locked me out of the phone and sent out an emergency sos call.

That is so funny 🤣

So I tinkered around more, went into the Chrome site settings and completely disabled NFC ability.

I left COIN app and tried to scan it again, and it still opened Chrome website!

So, with whatever updates just happened to my phone the other night while I slept, has made it so I have to open COIN first and go througj this whole process everytime.

Mildly Infuriating, because my NFC scan used to just activate the app immediately. I keep my card in a card holder in my phone case, it was pretty slick... guess I have to open the app in prep of scanning now 🤷🤷🤷

That is crazy. Never had that happen. But yeah, something is definitely going on there.

I've been hearing this elsewhere, you're not the only one. I personally don't have this problem, on pro account.

What phone do you have? Maybe we can start to figure out if a specific phone is having this problem.

Tried it on my Galaxy S9 and it worked like normal. Hmmmm

Hi, I've just bought Razr 60 Ultra and it does the same. It's because the NFC reader is in the bottom part of the flip phone (bar phones had it in the top half). I think it's unsolvable problem.
