Phone not ringing or missing notifications

1. Focus and Do Not Disturb

This is the most common cause. Look for a moon or Focus icon at the top of the screen.

2. Silent mode and volume

• iPhone: check the Ring/Silent switch or the Action button, and the ringtone volume in Settings → Sounds & Haptics.
• Android: press a volume button and tap the bell icon to set ring mode.

3. Calls going straight to voicemail

1. On iPhone, turn off Silence Unknown Callers (Settings → Apps → Phone) if you’re missing calls from new numbers.
2. Check the number isn’t blocked.
3. Check call forwarding is off, and Airplane Mode is off.
4. Poor signal at home? Turn on Wi-Fi Calling.

4. App notifications missing

1. Check the app’s notifications are allowed in your phone’s Notifications settings.
2. Check inside the app’s own settings (WhatsApp, banking and email apps have their own switches).
3. On Android, set the app’s battery use to Unrestricted or Optimised, not Restricted – and remove it from Samsung’s Sleeping apps list.
4. Turn off Low Power Mode or battery saver to test.

Still silent?

If you can’t hear ringtones or alerts even with every setting right, the speaker may be the problem – see speaker quiet or muffled.
