OK, to clarify.
I left iOS 2 years ago. Back then it was a great product. You could leave your phone on the table and it was secure. You knew, if you missed a call without unlocking it AND nobody without knowing your passphrase was able to call anybody from it.
Now, this is a huge security flaw! I have kids and even if I didnt, I work in an environment, where you cant take your phone with you all the time. I NEED to know, who called me without unlocking the phone. I NEED to have a secure phone.
I dont understand, why it isnt possible to make this functionality optional like it is for messages!!! Its either - you dont know who called you unless you unlock your phone or anybody can call back the contact you missed.
