Bogus Android Camera QR Code notification

Today I noticed an unusual silent notification supposedly coming from the default Samsung Camera app on my A70 Android phone. The message reads: 'Camera QR code scanned 11:46 Web page Tap here to go to "joinxr.uk" in your browse..' I say it's unusual because at 11:46 today my phone was screenlocked and sitting in my trouser pocket. I had not used it from 09:30 to 12:15 Being suspicious that perhaps my phone had been hacked I contacted Norton support on their website Chat facility but after experiencing several closures of the chat window not performed by me and the technician not being able to take control of the device using the Rescue+ app due to the "control" session being terminated from my end, again not initiated by me, I decided to contact Norton support on the phone... After getting through to the threat resolution specialist dept and relating the story again to the support rep (apparently not willing to look at the existing case log to get background info) I was told: "not to worry just ignore it. It's probably a notification that has come from your browser" He said that if I hadn't allowed access to my phone by anyone or downloaded any dodgy apps I had nothing to worry about (which I hadnt). If that's the case and that's all you need to do then it begs the question as to whether we need to bother installing Norton360 on our Android devices at all...?! Is this possible that someone can create a Camera app QR code notification via a browser (I'm using Edge) showing a link to any URL they want you to visit? Shouldn't Norton360 be stopping this kind of activity (if it is indeed possible) or at least even expressing an interest in it?? When I asked to be put through to someone else who might be a bit more interested I was promised a callback within 30 mins. Still waiting and TBH not holding my breath. What are other peoples take on this whole thing? The actual problem, the response and the suggested resolution... Martin Norton360 ver 5.56.0.230302003 Android ver 11 Kernel ver 4.14.190-24363203
