Also encryption by default and much larger user base mean there is more focus on iOS than Android (like the old windows versus mac virus argument) the difference I see is that you are much more likely to get compromised by an application on Android than iOS. And since Google has been very friendly with the USG I would find it much more likely that Enclave or not that it will be NSA weakened crypto that will be the demise of your Android rather than exotic exploits of your wifi. And if your paranoid you carry a Nokia 7715 and extra SIMs or you back something Debian based like Purism.

I don't think there's any truth to this - if the crypto were weakened you'd see it broken by that quite quickly - but it's quite strong and follows well accepted stands in the cryptography community, have a look yourself if you like. It's using dm-crypt and dm-crypt is fairly heavily tested and reviewed. Debian and likely Purism use the exact same, so certainly wouldn't be any better in that way.
