Change the app's category, not just the phone default
To give an Android app its own notification sound, open its notification settings and look for a category or notification type with a Sound option. Select the relevant category, choose a tone and save where prompted. Changing the phone's default notification sound may not replace an app's category-specific choice.
A messaging app can have separate categories for messages, calls and background activity. This means there may be several sounds to check within one app. Start with the category that matches the alert you want to recognize, rather than changing every setting at once.
Google Pixel route
Google's current instructions use Settings, then Notifications, App notifications and the app's name. Open Notification categories, choose the category, tap Sound and select a tone. Save the selection if that control is shown. The names you see inside the category list depend on the app.
If a notification is already visible, its settings shortcut can help you identify the relevant app or category. Do not assume that two similarly named message categories perform the same job; change one, then request a test notification to confirm it.
Samsung Galaxy route
On newer Galaxy software, category controls may need to be enabled first. Open Settings, Notifications and Advanced settings, then enable Manage notification categories for each app if it is available. Next, open the target app's notification settings through Settings and Apps. Select a notification category and its Sound control, then choose the tone.
Tap the category name rather than only toggling its switch. Turning a category off prevents those notifications; it does not open the sound picker. Samsung's menus vary by model and software version, so follow the labels on your device.
Use a downloaded sound
On supported Galaxy phones, Samsung documents copying an audio file into the Notifications folder in internal storage using My Files. Return to the sound picker afterward and look for the file. If a different Android phone offers an Add or file-selection control, follow that device's picker instead.
Choose a short, clear alert rather than a long song. A spoken phrase may expose information when it plays in public, and a lengthy effect can become distracting in an active group chat. Preview any sound effect before assigning it. The visual style of a sound button does not tell you whether its audio suits an alert.
Give each sound a clear purpose
Try a brief neutral sound for routine messages and a distinctly different tone for an app you check promptly. Test both at a moderate volume through the phone speaker. Two clips that sound different in headphones can be difficult to distinguish in a bag or a noisy room.
You do not need a unique sound for every application. Start with two important apps and leave the rest on the default or silent according to your preferences. That makes the system easier to remember and reduces unnecessary interruptions.
If the sound option is missing
Check whether you have opened an actual category instead of the app's overall notification page. Then look inside the app's own settings: some apps manage alert choices there. If the category offers only silent behaviour, or the app does not expose a selectable tone, a universal setting cannot force that feature to appear.
If the selected sound does not play
- Check that notifications are allowed for the app and the relevant category.
- Make sure the category is configured to alert rather than remain silent.
- Check notification volume and any active Do Not Disturb or similar mode.
- Send a new test notification from another device or account where appropriate.
- Compare with a built-in tone to determine whether the issue involves your downloaded file.
Do not rely on preview playback alone: the picker playing a sound proves the file can play there, not that an incoming alert is assigned to that category. Read ringtone versus notification sound if you are trying to change call audio instead.

Frequently asked questions
Will this change incoming phone calls?
Not necessarily. The phone ringtone is a separate setting. Use our Android ringtone guide for ordinary calls.
Why did only some alerts change?
The app may use more than one notification category or a separate in-app sound setting. Identify the alert type that still uses the old sound and review that category.
