Missing Snapchat notifications on your OnePlus 15 can make you miss messages, snaps, and calls without realizing it. The app may still work when you open it, but alerts never show up on the lock screen or notification panel. This issue is usually caused by notification restrictions, battery optimization, or background limits in OxygenOS, and it can be fixed with a few careful checks.
Why Snapchat Notifications Are Not Working on OnePlus 15
- Notifications are disabled for Snapchat in system settings.
- Battery optimization is restricting Snapchat in the background.
- Background data or background activity is limited.
- Do Not Disturb or Focus modes are blocking alerts.
- The Snapchat app is outdated or misconfigured.
1. Make Sure Snapchat Notifications Are Enabled
If notifications are turned off at the system level, Snapchat cannot alert you even if in-app settings are correct. This is the most common reason notifications stop working.
Open Settings, and then tap Notifications.
Tap App notifications, and then select Snapchat.
Turn on Allow notifications, and make sure all alert categories are enabled.
2. Check Snapchat In App Notification Settings
Snapchat has its own notification controls that can silently block alerts. Even if system notifications are on, the app itself may still be muted.
Open Snapchat, and then tap your profile icon.
Tap Settings, and then tap Notifications.
Enable all alerts you want to receive, including messages and calls.
3. Disable Battery Optimization for Snapchat
Battery optimization can prevent Snapchat from running properly in the background. When this happens, notifications only appear after you open the app.
Open Settings, and then tap Battery.
Tap App battery management, and then select Snapchat.
Choose Unrestricted or Allow background activity.
4. Allow Background Data and Activity
If background data is restricted, Snapchat cannot sync notifications in real time. This can delay or completely block alerts.
Open Settings, and then tap Apps.
Tap Snapchat, and then tap Data usage.
Turn on Allow background data and unrestricted data usage.
5. Check Do Not Disturb and Focus Modes
Do Not Disturb can silence notifications without blocking the app itself. Many users forget it is enabled, especially if it runs on a schedule.
Open Settings, and then tap Sound and vibration.
Tap Do Not Disturb, and then turn it off.
Check schedules and exceptions to ensure Snapchat is not blocked.
6. Update Snapchat and Restart the Phone
An outdated app or temporary system glitch can interfere with notifications. Updating and restarting often clears hidden bugs.
Open the Play Store, and then search for Snapchat.
Tap Update if available, and then close the store.
Restart your phone and test notifications again.
Once Snapchat notifications are properly allowed and unrestricted, alerts should arrive instantly on your OnePlus 15. Most notification issues come down to background limits or battery controls, and fixing those restores normal behavior quickly.
FAQs
Why do Snapchat notifications only show up when I open the app?
This usually means battery optimization or background activity is restricting Snapchat. Setting the app to unrestricted background use fixes the issue.
Does clearing Snapchat cache help with notification issues?
In some cases, yes. A corrupted cache can affect app behavior, but notification settings should be checked first since they are the most common cause.
Can system updates affect Snapchat notifications?
Yes. Software updates can reset app permissions or battery rules, which may disable notifications until they are manually reenabled.
