Missing Instagram notifications on the lock screen can make you miss messages, comments, or important alerts. On the OnePlus 15, this usually happens because notification permissions, battery controls, or lock screen settings are blocking the app. The fixes below focus on the most common causes and help restore Instagram alerts so they appear properly in 2025.
Why Instagram Notifications Are Not Showing on the Lock Screen
- Instagram notifications are disabled or limited in system settings.
- Lock screen notification display is turned off or restricted.
- Battery optimization is preventing Instagram from running in the background.
- Background data usage is disabled for the app.
- System notification settings were changed after an update.
1. Make Sure Instagram Notifications Are Enabled
If notifications are disabled for Instagram, the app cannot show alerts on the lock screen or anywhere else. Turning them back on restores message and activity notifications.
Open Settings, and then tap Notifications.
Tap App notifications, and then tap Instagram.
Turn on Allow notifications, and make sure all alert categories are enabled.
2. Allow Instagram Notifications on the Lock Screen
Instagram may be allowed to send notifications but blocked from appearing on the lock screen. Enabling lock screen visibility ensures alerts show even when the phone is locked.
Open Settings, and then tap Notifications.
Tap Lock screen notifications, and then set them to show content.
Go back to Instagram notification settings and confirm lock screen display is allowed.
3. Disable Battery Optimization for Instagram
Aggressive battery management can stop Instagram from running in the background. This prevents notifications from appearing until you open the app manually.
Open Settings, and then tap Battery.
Tap App battery management, and then tap Instagram.
Set it to Allow background activity or No restrictions.
4. Enable Background Data for Instagram
If background data is turned off, Instagram cannot refresh notifications when the screen is locked. Enabling it allows alerts to come through in real time.
Open Settings, and then tap Apps.
Tap Instagram, and then tap Mobile data and Wi-Fi.
Turn on Background data and allow data usage while the screen is off.
5. Turn Off Do Not Disturb Mode
Do Not Disturb can silence notifications or hide them from the lock screen. Disabling it ensures Instagram alerts are not being suppressed.
Open Settings, and then tap Sound and vibration.
Tap Do Not Disturb, and then turn it off.
Lock your phone and wait for a new Instagram notification to test.
6. Restart Your Phone
A restart refreshes system services and fixes temporary notification bugs. It is a simple step that often resolves lock screen notification issues.
Swipe down from the top of the screen to open Quick Settings.
Tap the Power icon, and then tap Restart.
After rebooting, check if Instagram notifications appear on the lock screen.
Instagram notifications on the OnePlus 15 usually stop showing because of system restrictions rather than app errors. Once permissions, battery controls, and lock screen settings are configured correctly, notifications should appear instantly again.
FAQs
Why do Instagram notifications appear only when I open the app?
This usually happens when battery optimization or background data restrictions are enabled. Allowing background activity fixes delayed notifications.
Can OnePlus updates affect Instagram notifications?
Yes. System updates can reset notification or battery settings, which may block alerts until they are reenabled.
Do I need to reinstall Instagram to fix this issue?
In most cases, no. Notification issues are almost always caused by system settings rather than the app itself.
