How to Fix Galaxy S25 Messenger Notifications Not Working After Update
If Messenger notifications stopped showing on your Galaxy S25 after the latest update, the issue is usually caused by notification channels being reset, battery restrictions, adaptive battery rules, app-level mute settings, or a broken background sync session.
Use the steps below to fix a galaxy s25 messenger notifications not working after update problem and restore alerts reliably.
Fix #1: Check Messenger notification permission
Go to Settings > Notifications > App notifications and make sure Messenger is allowed. After a major update, Samsung can quietly reset app notification access.
Fix #2: Review Messenger notification categories
Open Settings > Apps > Messenger > Notifications and inspect each category. Message alerts, chat heads, previews, and silent channel settings can change after an update.
Fix #3: Remove battery restrictions for Messenger
Open Settings > Battery > Background usage limits and make sure Messenger is not sleeping or deep sleeping. Then go to Settings > Apps > Messenger > Battery and set it to Unrestricted if needed.
Fix #4: Turn off Do Not Disturb and notification routines
Check Settings > Modes and Routines and Settings > Notifications to make sure no mode is muting chat alerts during certain hours or locations.
Fix #5: Clear Messenger cache and sign back in if needed
Corrupted app data can break push delivery. Clear the app cache first. If notifications are still delayed, sign out of Messenger, restart the phone, and sign back in.
Fix #6: Update Messenger and Google Play services
Push alerts on Android rely heavily on Play services. Update both Messenger and Google Play services, then test with a new message.
Fix #7: Reset app preferences
Go to Settings > Apps > Reset app preferences. This restores disabled permissions, background limits, and notification defaults without erasing personal data.
Fix #8: Check network access on Wi-Fi and mobile data
If alerts only fail on one connection type, disable VPN, private DNS, or data saver temporarily. Messenger notifications can look broken when background network access is being filtered.
