Fix #1: Make sure Gmail sync is enabled

Gmail cannot pull new mail if sync was turned off for the Google account.

1. Open Settings > Accounts and backup > Manage accounts.
2. Select your Google account.
3. Tap Sync account and make sure Gmail is enabled.

Fix #2: Remove battery restrictions for Gmail

Samsung battery optimization can delay or stop background email sync.

1. Open Settings > Apps > Gmail > Battery.
2. Set it to Unrestricted or Optimized.
3. Check again if new messages arrive automatically.

Fix #3: Clear Gmail cache

Corrupted app cache is a common cause when sync breaks right after an update.

1. Go to Settings > Apps > Gmail > Storage.
2. Tap Clear cache.
3. Open Gmail and trigger a manual refresh.

Fix #4: Update Gmail and Google Play services

Old Google app components often misbehave after a new Android build.

1. Open the Play Store.
2. Install updates for Gmail, Google Play services, and Android System WebView.
3. Restart the Galaxy S25 and test syncing again.

If Gmail still does not sync on your Galaxy S25 after these steps, remove and re-add the Google account. That usually rebuilds a broken sync profile after an update.
