Phone: Sprint MWI Quirk: Phantom message wait indicator workaround (1/2)

If true, message wait indicators are hidden by default on this device
unless the user enables it in Call Settings. This quirk is necessary
for the "Phantom Voicemail" issue where notifications that are
impossible to dismiss on the Sprint network. In rare instances, feature
phone voicemail gets stuck in a Sprint account where smart phones are
unable to delete them. Sprint will not help the subscriber fix this,
as their own Android phones ignore message wait indicators.

When you enable 'sprint_mwi_quirk' in overlay/packages/services/Telephony/res/values/config.xml
this option appears in the Phone app:

Settings > Message Wait Indicator

Default is disabled, as Sprint Android phones have no reason to see
message wait indicators. It can however be enabled for Sprint phones
used on overseas carriers where message wait indicators are desired.

QuietHours: Change Logic (1/2)

Makes sense to me that turning QuietHours
    on should TURN QUIET HOURS ON with
    default time constraints applied.

I.E. QuietHours between 12:00am && 12:00am
    means QuietHours all day.  Having to
    adjust end time to 11:59 is redundant
    and not exactly the clearest implementation.
    Especially when we have a QuickToggle that
    directly toggles the setting on/off.
