I find some of the setting choices on the new Do Not Disturb feature more than a little confusing. Example: The first setting is Manual and if it is invoked, it states that NO calls and alerts that arrive while the phone is locked will be silenced. Okay. But the Allow Calls From selection gives you several choices, among them Everyone, and if you choose Everyone, "No incoming calls or messages will be silenced." That conflicts with the first setting. The last setting, Silence, also gives choices, Always and Only while iPhone is locked. If you choose the latter, then "Incoming calls and notifications will be silenced while iPhone is locked." Except if you invoke some of the earlier choices, such as Allow Calls from Everyone? I realize life has many conflicts, but really. So...who actually understands all these seemingly conflicting choices, and would he or she please post some accurate instructions? Thanks!
