How to Fix Instagram Notifications Not Showing on vivo Y51 Pro Lock Screen

If Instagram notifications are not showing on your vivo Y51 Pro lock screen, the problem is usually caused by a lock screen notification setting, Instagram app permission, battery restriction, Do Not Disturb, or an in-app Instagram notification setting.

Start with the lock screen settings first. On vivo phones, Instagram needs notification permission and lock screen display permission before alerts can appear while the phone is locked.

Quick answer

To fix Instagram notifications not showing on your vivo Y51 Pro lock screen, go to Settings > Status bar and notifications > Instagram, then turn on Allow notification and Show on lock screen.

Next, open Instagram and check Profile > Menu > Settings and privacy > Notifications. Make sure Push notifications are not paused and that messages, likes, comments, and other alerts are enabled.

If that does not work, check battery saver, background app limits, Do Not Disturb, app lock, and Instagram’s notification categories.

Why Instagram notifications are not showing on the vivo Y51 Pro lock screen

Instagram notifications may not show on the lock screen if the phone is allowed to receive notifications but not allowed to display them on the lock screen.

That is the common trap.

You may still hear a sound. You may still see the notification after unlocking. But the lock screen stays empty because the lock screen display permission is off.

Other common causes include:

App notifications are disabled for Instagram
Lock screen notification content is hidden
Push notifications are paused inside Instagram
Battery saver is limiting Instagram in the background
Do Not Disturb is blocking alerts
Instagram notification categories are turned off
The app cache is causing delayed alerts
The phone needs a software or app update

Use the fixes below in order.

1. Turn on Instagram lock screen notifications in vivo settings

Start here because this is the most likely fix.

1. Open Settings.
2. Tap Status bar and notifications.
3. Tap Instagram.
4. Turn on Allow notification.
5. Turn on Show on lock screen.
6. Lock your phone and ask someone to send you an Instagram message to test it.

On some vivo software versions, the path may look slightly different. You may see Notification and status bar, App notification management, or Manage notifications instead.

The important setting is the same: Instagram must be allowed to show notifications on the lock screen.

2. Allow Instagram notifications from Android app settings

If the vivo notification menu looks correct, check Instagram’s app-level notification permission.

1. Open Settings.
2. Tap Apps.
3. Tap Instagram.
4. Tap Notifications.
5. Turn on Allow notifications.
6. Check that important alert types are enabled.

If Instagram notifications are blocked here, lock screen settings will not matter. The phone will stop Instagram alerts before they can appear anywhere.

3. Check Instagram’s in-app push notification settings

Instagram has its own notification controls. If these are paused or turned off, your vivo Y51 Pro may be ready to show alerts, but Instagram is not sending them.

1. Open Instagram.
2. Tap your profile picture.
3. Tap the menu icon.
4. Tap Settings and privacy.
5. Tap Notifications.
6. Make sure Pause all is turned off.
7. Open each section and enable the alerts you want.

Check these sections especially:

Messages
Likes
Comments
Mentions
Followers
Live and Reels
Posts and Stories

If only Instagram DMs are missing from the lock screen, focus on the Messages section first.

4. Show notification content on the lock screen

Sometimes the notification is allowed, but the phone is hiding the content for privacy.

This can make it look like Instagram notifications are not showing properly.

1. Open Settings.
2. Tap Status bar and notifications.
3. Look for Lock screen notifications or Display on lock screen.
4. Choose an option that shows notifications on the lock screen.
5. If available, allow notification content to be shown.

For privacy, you can choose to show the alert but hide the message content. That way, your vivo Y51 Pro can still show that Instagram has a notification without exposing the full DM preview.

5. Turn off Do Not Disturb

Do Not Disturb can silence Instagram alerts and stop them from appearing normally.

1. Swipe down from the top of the screen.
2. Look for Do Not Disturb.
3. Turn it off if it is enabled.

You can also check it from Settings:

1. Open Settings.
2. Tap Sound and vibration.
3. Tap Do Not Disturb.
4. Turn it off or adjust the schedule.

If Instagram notifications disappear only at night, during class, or during work hours, a Do Not Disturb schedule is probably the cause.

6. Allow Instagram to run in the background

vivo phones can limit background activity to save battery. That helps battery life, but it can delay Instagram notifications.

1. Open Settings.
2. Tap Battery.
3. Look for Background power consumption management or a similar option.
4. Select Instagram.
5. Allow Instagram to run in the background.

You can also check:

1. Open Settings.
2. Tap Apps.
3. Tap Instagram.
4. Tap Battery.
5. Choose an option that does not heavily restrict background activity.

If Instagram notifications arrive only after opening the app, background restriction is one of the strongest suspects.

7. Turn off Battery Saver or Low Power Mode temporarily

Battery Saver can reduce background activity and delay app notifications.

1. Open Settings.
2. Tap Battery.
3. Turn off Battery Saver, Low power mode, or similar power-saving options.
4. Lock your phone.
5. Test Instagram notifications again.

You do not have to keep Battery Saver off forever. This is a test.

If Instagram lock screen notifications work after turning it off, the issue is battery restriction. You can either keep Battery Saver off or adjust Instagram’s background permissions so it is not restricted as aggressively.

8. Check Instagram notification categories

Android lets apps split alerts into categories. Instagram may have notifications enabled overall, but certain categories may be turned off.

1. Open Settings.
2. Tap Apps.
3. Tap Instagram.
4. Tap Notifications.
5. Open Notification categories, if available.
6. Turn on the categories you need.

Look for categories related to:

Direct messages
Instagram Direct
Comments
Likes
Live videos
Followers
Reminders
Stories

If DMs are not showing but likes are showing, this is likely the fix.

9. Clear Instagram cache and restart your vivo Y51 Pro

A stuck app cache can cause delayed or missing notifications.

1. Open Settings.
2. Tap Apps.
3. Tap Instagram.
4. Tap Storage.
5. Tap Clear cache.
6. Restart your phone.

Do not tap Clear data unless you are ready to sign back in. Clearing cache is safer because it removes temporary files without deleting your Instagram account.

After restarting, open Instagram once, then lock your phone and test notifications again.

10. Update Instagram and your vivo Y51 Pro software

If the issue started after an update, another update may fix it.

Update Instagram:

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

Update your vivo Y51 Pro:

1. Open Settings.
2. Tap System update.
3. Download and install any available update.

After updating, restart the phone. Then test Instagram lock screen notifications again.

What to do if Instagram notifications still do not show

If all 10 fixes are done and Instagram still does not show notifications on the vivo Y51 Pro lock screen, try uninstalling and reinstalling Instagram.

Before reinstalling, make sure you know your Instagram login details.

1. Long-press the Instagram app icon.
2. Tap Uninstall.
3. Restart your phone.
4. Reinstall Instagram from the Google Play Store.
5. Sign in.
6. Allow notifications when prompted.
7. Recheck lock screen notification settings.

If notifications still fail after reinstalling, the issue may be with Funtouch OS, Instagram’s current app version, or a deeper system setting. At that point, check for a vivo system update or contact vivo support.
