How to Fix Signal on iOS 16

If you’ve recently upgraded to iOS 16 and suddenly found Signal acting up — maybe messages aren’t sending, notifications are missing, or the app is crashing — you’re not alone. From my own experience using Signal on iPhone daily, iOS updates can sometimes throw a wrench in the works. Luckily, most Signal hiccups on iOS 16 have straightforward fixes. Let me walk you through what’s worked for me and what I’ve learned along the way.

Common Signal Problems on iOS 16

Before diving into solutions, it helps to recognize the most frequent issues Signal users face after upgrading to iOS 16:

Messages not sending or receiving – Sometimes Signal freezes or won’t connect properly.
Notifications not showing up – You might miss important calls or texts.
App crashing or freezing – Signal might close unexpectedly or lag.
Sync problems with linked devices – Desktop or tablet versions don’t sync messages.

Now, let’s tackle how to fix Signal on iOS 16 step by step.

Step-by-Step Fixes for Signal on iOS 16

1. Check Signal’s Permissions

iOS 16 is pretty strict about app permissions, and sometimes Signal can lose access to the essentials it needs to work smoothly.

Open Settings on your iPhone.
Scroll down and tap Signal.
Make sure permissions like Notifications, Background App Refresh, Microphone, and Contacts are turned on.
Especially ensure Notifications allow Lock Screen, Notification Center, and Banners. Without this, you won’t get message alerts.

One quirk I noticed: even if notifications are on, toggling them off and then back on can sometimes jump-start Signal’s notification system.

2. Force Close and Restart Signal

Whenever Signal feels stuck or won’t send messages, a quick force close often helps:

Swipe up from the bottom of the screen and pause (or double-click the Home button on older models) to open the app switcher.
Find the Signal app preview and swipe it up off the screen to close it.
Wait a few seconds, then reopen Signal.

This simple trick resets the app and can clear minor glitches after iOS updates.

3. Update Signal to the Latest Version

Signal’s developers are quick to push out updates to fix bugs—especially after major iOS releases.

Open the App Store.
Tap your profile icon in the top right corner.
Scroll to see if Signal appears in your pending updates.
If yes, tap Update.

Running an outdated version of Signal on iOS 16 can cause unexpected crashes or syncing issues.

4. Restart Your iPhone

Sometimes the issue isn’t Signal, but iOS itself. I always recommend giving your phone a quick reboot before diving deeper:

Press and hold the side button and either volume button until the slider appears.
Slide to power off.
After it’s off, press and hold the side button again to turn it back on.

This can clear temporary system hiccups that affect app behavior.

5. Reset Network Settings

Signal relies heavily on a solid internet connection. If you notice messages stuck in limbo or calling failures, resetting network settings can help—just be aware this deletes saved Wi-Fi passwords.

Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
Confirm and enter your passcode if prompted.
Your iPhone will restart with fresh network settings.

After this, reconnect to Wi-Fi and check Signal again. It’s a bit of a hassle but often fixes connectivity glitches.

6. Check Signal’s Official Status and Support

If none of the above fixes work, it’s worth checking if Signal has any known issues or updates specific to iOS 16. Visit signal.org and their support pages for the latest news.

Sometimes a fresh update or a server-side fix is needed, and they’ll usually post announcements or workarounds.

Tips & Tricks from a Longtime Signal User

After years of relying on Signal, here are a few lesser-known tips that might save you some headaches:

Backup your Signal data carefully. iOS 16 changed some file access rules, so make sure your Signal backups are up to date. Signal itself doesn’t do cloud backups by default, so use their encrypted backup feature under Settings > Chats > Chat backups.
Toggle Airplane Mode. If messages are stuck sending, switching Airplane Mode on and off sometimes resets network connectivity faster than rebooting.
Try reinstalling Signal as a last resort. If the app continues crashing or freezing, uninstall Signal and then reinstall from the App Store. Just make sure your messages are backed up first!
Linked Devices Sync Quirks. If your Signal desktop or tablet isn’t syncing, un-link and re-link your iPhone. Go to Signal Settings > Linked Devices and remove then add your device again. It’s a bit annoying but usually solves sync troubles.
