How to disable calling back from notification when iPhone is locked?
When the phone is locked and I get a missed call I can just swipe it and it will call without requiring the passcode. How can I disable this function so that I need to enter the passcode?
It is not possible, but will be soon.
As of right now, there is no toggle that can disable returning missed calls from the lockscreen, however, in iOS 11 (which will be publicly released in Fall 2017), you can disable this feature by toggling the switch in Settings > TouchID & Passcode > Return missed calls
