How to change the notification sounds in Lumia 950 & 950 XL?
You can customize the sound per app. It’s not very obvious in the Settings, so I’ll show you how to do it.
- Go to Settings (Swipe down from top of the screen and tap All Settings)
- Tap System > Notifications & actions
- Tap an app from the list to change its default notification sound
- Select a sound under the Notification sound list. You can tap the play button next to the sound for a preview.
That’s it! You’ll need to do this for each app that you want to change the notification sound for. These instructions also work for other devices with Windows 10 Mobile.
You don’t need to pick the same sound for each one. For example, I’ve changed the notification sounds for the apps I frequently use: Messaging app, Facebook Messenger, Outlook Mail, 6tag, and Slack Beta.
