It's unfortunate that I can't get security patches. I'm not willing to update to iOS 76 to get the fixes because I don't want to run code that is tested on an A12 on my 5 year old phone, and I don't want to buy a new phone because this one works fine and isn't larger than my hands.
No. But it probably has known unpatched vulnerabilities, and you're putting yourself and people around you in danger of a security hack.
