Notifications not always coming thru since Android 15 Update

Troubleshooting Notification Issues on Android 15: When Reminders Fail to Trigger

As Android 15 continues to roll out across various devices, many users are discovering unforeseen hiccups in their device’s functionality. One common concern that has surfaced involves the reliable delivery of notifications and reminders — a feature critical for productivity and daily planning.

The Issue: Missing Reminder Alerts Post-Android 15 Update

Since upgrading to Android 15 on my Galaxy S21+, I have noticed a significant change in how my device handles scheduled notifications. Specifically, reminders set through my preferred apps are not alerting me at their designated times.

Here’s a typical scenario: I set a reminder around noon to call my grandmother. Prior to the upgrade, I could count on my phone to notify me exactly at 12 pm. However, after updating, the notification failed to appear. The reminder remained silent, and I only discovered it later by chance when I checked my phone manually.

This issue appears to persist regardless of the method used to set the reminders. Even when I manually set a notification for today, it never triggered, and I only learned about it by opening my device and querying the reminder app.

Changes in Android 15 and Their Possible Impact

One notable change in Android 15 involves the new power button interaction — now a prolonged press to turn on certain features like Gemini (a placeholder for specific device functionalities). While this update aims to enhance security and user experience, it might inadvertently interfere with background processes, including notifications and alarm management.

Troubleshooting and Workarounds

If you’re experiencing similar issues, consider these steps to troubleshoot:

1. Check Notification Settings:
2. Ensure that notification permissions are enabled for your reminder or task management apps.

3. Confirm that Do Not Disturb mode is off during your scheduled reminder times.

4. Update Your Apps:

5. Make sure all related apps are updated to their latest versions, as developers often release patches addressing compatibility issues with new OS versions.

6. Reset App Preferences:

7. Sometimes, resetting app preferences can resolve conflicts impacting notifications.

8. Adjust Screen Timeout and Battery Optimization Settings:

9. Review battery optimization settings to prevent the system from restricting background activities critical to notification delivery.

10. Use Alternative Reminder Methods:

11. Consider switching to system alarms or third-party reminder apps known to be more resilient after OS updates.
