Re: [web-nfc] New Tag Scanned problems from PWA (#674)

New findings from today:

**TL:DR** All the phones and android versions where I encountered the issue don't have the problem anymore.

Devices I tested on where I received an "New Tag Scanned" popup when scanning my NFC tag:
- Samsung Galaxy 25, Android Version 16
- Samsung Galaxy 22, Android Version 16

I tested on both of these devices today, and none of them encounter the "New Tag Scanned" popup anymore. So seemingly overnight, the problem disappeared.

**What changed:**
For one of the phones, Galaxy 22, I was prompted with a new software update. I did some testing, and it had a **Android security patch level from 1 October 2025**.  Before I installed the new update, I made sure to check this version and test the issue. I was able to replicate the "New Tag Scanned" popup consistently. After installing the software update, the phone changed to **Android security patch level from 1 November 2025**. After this was installed, I can no longer replicate the issue. No popup appears, and the data from the tag is read and processed fine. Tested on both web-nfc-example website (linked further above) and our own PWA application. So it looks like a security update fixed the issue.

**Why?**
I wanted to get an idea of what this security update changed (https://source.android.com/docs/security/bulletin/2025-11-01). But because its security, they dont mention any affected/changed feature sets. I was hoping they would mention something about "NFC" or activities or intent or anything related. But they dont write about those details.

Any thoughts on this? Does this happen often? Anything I missed?
