iOS has many strengths, but in-app settings are not. Sure, third-party apps are often shipped with a set gear, but stick apps? Under no circumstance. To change settings in music, photos, camera, and other Apple apps, you must exit the app. However, there is a hidden trick to quickly access the settings of an app – without having to manually open the Settings app itself.
Let's say you play music and listen to your favorite song if you want to turn up the bass. No problem, as the Settings app has an EQ option for music. Instead of leaving music, opening Settings, and then tapping Music, try the following:
Hey Siri, open the Preferences.
Then watch in astonishment as iOS automatically opens the music settings page. The trick only works with "Preferences," not "Preferences," since the latter will only open the Settings app for the page you were on before, or for the main screen.
And hey, Siri is not the only way to do that. You can use the Home or Page key combination to activate Siri or Type to Siri to formulate "open settings." In iOS 1
Hey Siri, Settings
Done. Ask Siri to open "Settings" or "Preferences" in an app, stock or third-party, and iOS will go to the settings page. You can also add the name of the app to your Siri command to open this settings page wherever you are (for example, "Open Music Preferences" if you're in the Notes app).
Hey Siri, open [App Name] preferences
That means it's not a perfect system. For example, if you use the trick in the camera, the photos settings will be opened. Not very helpful. If you do this for Measure, TV, and Wallet & Apple Pay, the Settings app opens on the last page you opened.
We suspect that Apple encoded the shortcut for its standard apps in Siri at least before iOS 9. Why? Since then, "Photos & Camera" had up to iOS 11 combined settings. Measure was not even an app before iOS 12. TV was a brand new app in iOS 10.2. Passbook was renamed Wallet & Apple Pay in iOS 9. None of them works.
All third-party apps seem to work, which is also interesting for Apple Stock Apps. Specifically, the trick works under shortcuts in iOS 12, but not in iOS 13, because of switching from an installable app to a standard app.
Hopefully, Apple cleans up the feature so it works in all cases of the Stock Apps.
