Volume Panel Android 7.1.1 Ever since Android 7.1.1 I am unable to find the page (activity screen) to set, on one screen, the volume for the various audio outputs, such as notificatios, media, etc. Is there such a screen inherent in Android 7, or do I need to find an app for that.  Thanks for your help.
Yes this is found under Settings → Sound i.e



If for some reason you can't find it or is hidden, then just grab a third-party activity launcher application from playstore e.g Quick shortcut to access com.android.settings/com.android.settings.Settings$NotificationSettingsActivity


Install Quickshortcutmaker from Playstore
Select normal search - under input box type sound and click search


  


In search results it will show Settings click it,  and expand the list you will find "Sound &amp; Notification"  then click try (or create shortcut by pressing create).
