How to Fix Snapchat Notifications Not Working on vivo Y51 Pro

If Snapchat notifications are not working on your vivo Y51 Pro, the problem is usually caused by disabled notification access, muted Snapchat alerts, battery restrictions, background data limits, Do Not Disturb, or an outdated app.

Start with the simple checks first. Make sure Snapchat notifications are turned on inside the app and in your vivo phone settings. Then check battery, data, lock screen, and background activity settings.

Quick answer

To fix Snapchat notifications not working on vivo Y51 Pro, open Snapchat, tap your profile icon, tap the Settings gear, then go to Notifications and make sure alerts are enabled. After that, go to Settings > Apps > Snapchat > Notifications on your vivo Y51 Pro and allow Snapchat notifications.

If Snapchat alerts still do not appear, turn off Do Not Disturb, allow background data, remove battery restrictions, clear Snapchat cache, update the app, and restart your phone.

Why Snapchat notifications stop working on vivo Y51 Pro

Snapchat notifications can stop working on your vivo Y51 Pro when either Snapchat or Android blocks alerts. This can happen after an app update, system update, permission reset, battery optimization change, or accidental mute setting.

Common causes include:

Disabled Snapchat notifications
Muted chat or story alerts
Do Not Disturb mode
Battery Saver or background restriction
Mobile data or Wi-Fi issues
Data Saver blocking background activity
Outdated Snapchat app
Corrupted app cache
Silent notification category
vivo system settings limiting background apps

Here are the 10 fixes to try.

1. Turn on notifications inside Snapchat

Start inside Snapchat because the app has its own notification controls. Even if Android notifications are allowed, Snapchat may not send alerts if they are turned off in the app.

1. Open Snapchat.
2. Tap your profile icon.
3. Tap the Settings gear.
4. Tap Notifications.
5. Turn on the notifications you want to receive.
6. Make sure message, story, mention, friend suggestion, and call alerts are not disabled.

Snapchat’s own support page says Android users can control Snapchat alerts from the app’s Notifications menu. So this should be your first check before changing deeper phone settings.

If only one friend’s alerts are missing, the problem may be a muted conversation rather than a phone-wide notification issue.

2. Allow Snapchat notifications in vivo settings

Next, check whether your vivo Y51 Pro is blocking Snapchat at the system level.

1. Open Settings.
2. Tap Apps.
3. Tap See all apps or App manager.
4. Tap Snapchat.
5. Tap Notifications.
6. Turn on Allow notifications.
7. Check each notification category and make sure important alerts are enabled.

Look for categories such as chats, calls, stories, reminders, mentions, or silent notifications. The exact names can vary depending on your Android and Funtouch OS version.

If Snapchat notifications are set to Silent, change them to Alerting so your phone can show sound, vibration, or pop-up alerts.

3. Check if Do Not Disturb is turned on

Do Not Disturb can block Snapchat alerts even when every Snapchat setting looks correct.

1. Swipe down from the top of the screen.
2. Look for Do Not Disturb.
3. Turn it off if it is enabled.
4. Open Settings.
5. Tap Sound and vibration.
6. Tap Do Not Disturb.
7. Check schedules, exceptions, and app permissions.

This matters if Snapchat notifications work during the day but disappear at night, during work hours, or when the phone is locked.

Also check Focus mode or any similar feature on your vivo phone. If Snapchat is paused or blocked during a focus schedule, notifications may not appear until the mode ends.

4. Turn off Battery Saver and allow Snapchat to run in the background

Battery settings are one of the most common reasons Snapchat notifications arrive late or only show up when you open the app.

1. Open Settings.
2. Tap Battery.
3. Turn off Battery Saver or Low power mode.
4. Go back to Settings.
5. Tap Apps.
6. Tap Snapchat.
7. Tap Battery.
8. Choose Unrestricted or Don’t optimize if available.

On some vivo phones, the wording may be slightly different. Look for options related to background power use, battery optimization, high background power consumption, or app power management.

If your vivo Y51 Pro aggressively closes Snapchat in the background, message alerts may not arrive on time.

5. Allow background data for Snapchat

Snapchat needs an internet connection in the background to receive messages, calls, and story alerts. If background data is blocked, notifications may only appear after you open the app.

1. Open Settings.
2. Tap Apps.
3. Tap Snapchat.
4. Tap Mobile data and Wi-Fi or Data usage.
5. Turn on Background data.
6. Turn on Unrestricted data usage if you use Data Saver.

Then check your connection:

1. Switch from mobile data to Wi-Fi.
2. Open Snapchat.
3. Ask someone to send a test message.
4. Lock your phone.
5. Wait to see if the notification appears.

If Snapchat notifications work on Wi-Fi but not mobile data, your mobile data settings, signal, or carrier connection may be the issue.

6. Check lock screen notification settings

Sometimes Snapchat notifications are working, but they are hidden from the lock screen.

1. Open Settings.
2. Tap Notifications and status bar.
3. Tap Lock screen notifications.
4. Allow notifications on the lock screen.
5. Go to Snapchat notification settings.
6. Make sure Snapchat can show lock screen alerts.

You may also see privacy options such as:

Show all notification content
Hide sensitive content
Do not show notifications

Choose the option that fits your privacy preference. If you want to see Snapchat alerts without opening the phone, avoid blocking lock screen notifications completely.

7. Unmute Snapchat chats and story notifications

If Snapchat notifications work for some people but not others, check whether you muted a specific chat, call, or story.

To check chat notifications:

1. Open Snapchat.
2. Go to the Chat screen.
3. Press and hold the friend’s name.
4. Tap Chat and Notification Settings.
5. Tap Notification Settings.
6. Make sure chats or calls are not muted.

To check story notifications:

1. Open Snapchat.
2. Tap your profile icon.
3. Tap the Settings gear.
4. Tap Notifications.
5. Check story notification settings.

This is a common issue because it feels like Snapchat notifications are broken, even though only one conversation or story source is muted.

8. Clear Snapchat cache

A corrupted cache can cause small app problems, including delayed alerts, missing notification badges, or app behavior that does not match your settings.

1. Open Snapchat.
2. Tap your profile icon.
3. Tap the Settings gear.
4. Scroll down to Account Actions.
5. Tap Clear Cache.
6. Confirm the action.
7. Restart Snapchat.

You can also clear cache from Android settings:

1. Open Settings.
2. Tap Apps.
3. Tap Snapchat.
4. Tap Storage.
5. Tap Clear cache.

Do not tap Clear storage unless you are ready to reset the app’s local data and sign in again.

9. Update Snapchat and your vivo system software

If the issue started after an update, another update may already include a fix. Update Snapchat first, then check your vivo phone software.

To update Snapchat:

1. Open Google Play Store.
2. Search for Snapchat.
3. Tap Update if available.

To update your vivo Y51 Pro:

1. Open Settings.
2. Tap System update.
3. Check for updates.
4. Install any available update.
5. Restart your phone.

Also open the vivo app store if your phone uses it for some app updates.

After updating, send yourself a test notification or ask a friend to message you on Snapchat. Leave the phone locked for a few minutes and check whether the alert arrives normally.

10. Reinstall Snapchat

Use this as the final app-level fix. Reinstalling Snapchat can reset broken permissions, notification categories, cached files, and app configuration.

1. Press and hold the Snapchat app icon.
2. Tap Uninstall.
3. Restart your vivo Y51 Pro.
4. Open Google Play Store.
5. Install Snapchat again.
6. Log in.
7. Allow notifications when prompted.
8. Check Snapchat notification settings again.

After reinstalling, do not skip the notification permission prompt. If Android asks whether Snapchat can send notifications, choose Allow.

If Snapchat still does not send notifications after reinstalling, test other apps like WhatsApp, Messenger, Gmail, or Instagram. If multiple apps have notification problems, the issue is probably with vivo system settings, battery management, network access, or Do Not Disturb rather than Snapchat alone.

What to do if Snapchat notifications still do not work

If none of the 10 fixes worked, check whether the problem affects only Snapchat or all apps.

If only Snapchat is affected, report the issue through Snapchat support or wait for an app update. If all apps are affected, check your vivo notification settings, battery restrictions, data settings, and system updates again.

You can also try resetting app preferences:

1. Open Settings.
2. Tap Apps.
3. Tap the menu icon.
4. Tap Reset app preferences.
5. Confirm.

This can restore disabled apps, default notification settings, and permission-related behavior. It should not delete your personal files, but you may need to recheck app permissions afterward.
