Turned on Passcode Lock with requiring passcode after 1 minute, but doesn't

Question

I turned on the Passcode Lock with Erase Data feature. It has a field for 'Require Passcode' and gives 6 options (immediately, after 1 min, after 5 min, etc). I selected after 1 minute, yet it never requests the passcode if someone calls me and I answer the phone. I can talk on the phone, surf the web (while even on the phone or not), etc. It never prompts for the passcode. So, what's the 1 minute for????

Answer 1

Passcode will never stop a call from being picked up.
The 1 min is once the screen is locked, it will countdown to 1 min. After a min it will fully lock meaning to operate the phone again you will have to enter a passcode.
To fully test and make sure things are just not happening too soon during your tests.
Set it for passcode and 1 min like you said you have.
Press the lock button on top (to make screen turn off).
Don't touch it for over 1 min.
Then press home (or lock) to activate.
Slide to unlocked.
Here is should ask for a passcode.
You may wish to also reboot just to make sure nothing is hosed in memory.
To reboot, press and HOLD both the HOME and LOCK buttons.
DO NOT let go when it says to slide to turn off, but keep holding both.
Screen will flicker off but DON'T let go.
Once you see the Apple Logo, then you can let go.
That is how to do a full cold reboot of the phone. No data or settings will be lost and only takes as long as it takes the phone to boot up.
This is the fix to just about every problem you ever may face with the phone (remember, it is a computer and a new OS at that. So reboots are needed now and then just to clear the cobwebs/memory leaks).
