Why does iPhone require passcode immediately?
I am new to iPhone, and have one running IOS 10.3.1.
In contrast to my iPad, which when turned on within 15 minutes of being turned off, turns on without requiring its passcode, my iPhone seems to require it all the time, immediately after being awoken. In the Touch ID and Passcode settings, under Require passcode, it says immediately, and that cannot be changed.
