So would my 5 minute passcode lock "override" the 1
minute auto-lock?
There is no 5-minute passcode lock. You have them backwards. 🙂
Auto-lock (which is more like "sleep") is the one that has the various times you can select. But the screen does "lock," in that you have to swipe your finger across the screen to "unlock" it.
Passcode lock adds the 4-digit code to the process. The time you've specified for Auto-lock (1-5 minutes) still applies. The display will go to "sleep" (i.e., "auto-lock") within that amount of time.
But say you've just put the phone down temporarily -- right in front of you, while you're doing something else -- and you see it go to "sleep." Do you want to have to enter your passcode
immediately, or do you want a 1-minute "grace period," giving you the chance to pick up your phone and "wake it up" without having to enter the code? That "grace period" is what "After 1 min." means on the Passcode Lock page.
