Android has a lot of vulnerabilities and many others added to the manufacturer's customization layer. 

Only with the pixels you have better security and still not even close to iOS.

Only GrapheneOS offers good security.

I don't think you have much idea what you are talking about. 

 Man, obviously when I'm saying about Android is Android itself, not fucking Chinese customization. 

 Ok, let's being real, any customization by smartphones manufacturers is a shit, just Samsung-Knox is sightly better than others.
 

 I have given you a lot of examples, even grapheneos itself says so, stop talking nonsense, some of you are capable of selling your mother just for wanting to be right. 

 Man, you started saying FreeBSD is the securiest OS 

 You're retarded, aren't you?

You can't even read.

OpenBSD (Not freeBSD) is considered the most secure operating system for many reasons, at least as far as servers are concerned.

For other things we have QubesOS.

For mobile devices we have grapheneOS.

But that said, you are an imbecile who can't even read, I don't waste my time with you. 

 Oh yeah, I'm retard because of a typing mistake. And I'm still learning english, just saying 

 If you don't believe me said by the grapheneos people themselves.
