Of course you can have highest security if you just enable the single calling feature on a capable phone with beefy specs like iphones. I'm totally worry free in the safety issue as I know what I'm doing. Of course not everyone is techie and I think iphone is the best suit for them. All I want is a phone that can make my life easier and works the way I want, instead of letting the manufacturer decide how I should have use it.
If I'm given a new phone I will be happily discover new stuffs in that instead of feeling lost. Anyway this is not a point comparing a unified phone with the one with various branches.
Don't come Android, don't scare me like that leh you fruit fanboy.
Fruit fan will own AirPod.. and I don’t :O
