How to Fix Signal Notifications Not Working

If you rely on Signal for your private messaging, having notifications stop working can be frustrating. Whether it’s missing important messages or delayed alerts, it’s important to get your Signal notifications back in shape. As someone who uses Signal daily, I’ve encountered this issue a few times and found some reliable fixes. In this guide, I’ll walk you through practical troubleshooting steps to get those notifications buzzing again.

Common Reasons Signal Notifications Stop Working

Before diving into fixes, it helps to understand why Signal notifications might not work:

Let’s get practical and fix this.

Step-by-Step Fixes for Signal Notifications Not Working

1. Check Signal’s Notification Settings

This might seem obvious, but many users overlook Signal’s own notification controls.

  1. Open Signal and tap your profile icon (top-left on Android, or top-right on iPhone).
  2. Go to Notifications.
  3. Make sure Show Notifications is enabled.
  4. Check if Message Notifications and Group Notifications are turned on.
  5. Adjust the notification sound to something noticeable if you’ve accidentally set it to silent.
  6. Also, check if “Mute Notifications” is enabled for specific chats—this is a sneaky one that trips me up sometimes!

Bonus tip: Signal allows you to customize notifications per chat. If a particular conversation isn’t notifying you, double-check its individual settings.

2. Confirm System-Level Notification Permissions

Signal needs permission to send notifications at the system level. Here’s how to double-check:

On Android:

  1. Open Settings on your phone.
  2. Navigate to Apps & Notifications (or similar, depends on your device).
  3. Find and tap Signal.
  4. Go to Notifications.
  5. Ensure notifications are allowed and none are blocked.
  6. Check if any notification categories are silenced.
  7. Also, toggle “Allow Notification Dots” on for convenience.

On iPhone:

  1. Open Settings.
  2. Tap Notifications.
  3. Scroll to and select Signal.
  4. Make sure Allow Notifications is enabled.
  5. Check that alerts are allowed in Lock Screen, Notification Center, and Banners.
  6. Enable Sounds and Badges if you want those indicators too.

If any of these are off, your notifications won’t come through. I’ve personally missed messages because of a misplaced toggle here, so double-checking is worth it.

3. Disable Battery Optimization for Signal

Battery saver modes can prevent Signal from running background services, which stops notifications. Here’s how to fix it:

Android-specific:

  1. Go to Settings > Battery.
  2. Look for Battery Optimization or App Battery Saver.
  3. Find Signal in the list.
  4. Select Don’t optimize or Allow background activity.

This one fixed notification delays for me more than once, especially on phones with aggressive battery management (looking at you, Xiaomi and Huawei).

4. Check Your Phone’s Do Not Disturb Mode

It’s easy to forget that “Do Not Disturb” is on, especially when you’re in meetings or at night.

  1. Swipe down your phone’s quick settings panel.
  2. Look for the “Do Not Disturb” icon.
  3. If it’s enabled, tap to disable it or adjust settings to allow Signal notifications to break through.

On both Android and iOS, you can whitelist apps like Signal in DND settings. This way, important messages still alert you even when your phone is quiet.

5. Update Signal and Your Phone OS

Signal regularly pushes updates that fix bugs and improve notifications. Likewise, your phone OS updates can impact app behavior.

Sometimes, old versions of Signal or your OS cause quirky notification issues.

6. Reinstall Signal as a Last Resort

If none of the above steps work, reinstalling Signal can help reset any corrupted settings.

  1. Back up your Signal data if you want to preserve your message history (Signal allows encrypted backup; check signal.org for official instructions).
  2. Uninstall Signal from your device.
  3. Restart your phone.
  4. Reinstall Signal from your app store.
  5. Restore your backup if applicable, and set up notifications again.

I usually try everything else first, but reinstalling has saved me from annoying notification bugs before.
