I'm not sure why internet users like us and specially a crypto users needs to deal using same gadgets?
Phones nowadays are very cheap comparing to how much we have now in our crypto assets so better
not use or exploit your phone than using separate phones like what others said here and i believe
this is the best advise to do.

I would say not just for the crypto but overall the internet is filled with malware that can compromise our privacy so using phones that don't have any personal files should be the better option to connect to the internet but it isn't practical though and after all we are living in the era where people prefer storing everything over cloud storage over their phone.

Technically, everything is possible, any software product has loopholes, and most likely, if you decide to scan a QR code found on a random web page, you are potentially becoming a victim of scammers. Therefore, if you use such a tool, scan the QR code only in official verified places. No one is immune to this type of fraud, so do everything you can to protect yourself from it by checking sources and using best security practices. Fraudsters can exploit various vulnerabilities.

Technically yes and more likely possible if you choose to scan a QR code found on a random web page but you are less likely to be exposed to such malware if you scan a QR to pay vendors or restaurants and typically you will scan the QR code via the money paying app which will tell you that the QR code is a valid address and if not it gives you invalid that is what the security measures inbuilt in those apps.

Well in general, scanning a QR code itself is not a direct way to get malware on your phone but malicious QR codes can redirect you to websites that may attempt to exploit vulnerabilities in your device. So to stay safe, ensure your device's software is up-to-date and be cautious when scanning QR codes from untrusted sources.

Let's say you scan QR of an BEP20 address in your electrum then it will say the address is invalid so there will be no further actions to execute so even if you scan QR code that may lead to a malware website then you are less likely to be affected but if you do with your QR code scanner app then it will become a problem.

I ONLY use "old" 2G GSM and 3G UMTS mobile phones which means I DO NOT USE "smart phones" which means that I am 100% safe from malwares, viruses etc etc etc...

*happy me* Grin

If you are serious about this?? then you are a legend Cheesy

but I doubt this is real because
you need to have access to some sites also that needs smart phones or at least Iphones

like others or many of us suggest , better to have extra phones for browser this is the
only way we will be safer from those hacking and scamming .

at least now it is clearer for everyone to never scan unless they have no crypto
on those phones they uses.

better use multiple gadgets mate .

make sure to separate your wallet/holding gadget to those units that you used in browsing or watching movies or even gamings because those may contain malwares or malicious links.

If the QR code redirects to a website that contains a malware, you will get it on your phone, unless you have an anti-virus/malware. Usually, at least with my app, can check the url of the website it redirects too which will give you an indication if does look fishy.

but even anti virus sometimes are bypassed by malwares .

If you have a crypto wallet on your phone, can you get malware this way?

If you could afford another phone, why not buy a new one? Especially if you hold huge amount of bitcoin in your phone
we all should be careful since there are plenty ways to hack into someone’s phone

Well don't restaurants and stores have to scan the QR code to choose food or to pay?

If so, wouldn't that mean someone could manipulate the QR code or something like that?

Imagine it's a place where they require people to scan the QR and it's a public place. Can someone do something with that code though?

I have watched something like this on your mind when someone switched to their QR so they paid for the person that switched the QR instead of the store itself.

But when you do these payments through QR codes, the cashier or staff have to verify it first that they have received the payment before letting you go if someone has manipulated the qr.
