docs: Determines whether the simplified settings UI should be shown. This is
  true if this is forced via {@link #ALWAYS_SIMPLE_PREFS}, or the device
  doesn't have newer APIs like {@link PreferenceFragment}, or the device
  doesn't have an extra-large screen. In these cases, a single-pane
  "simplified" settings UI should be shown.
