Facebook Keeps Crashing on iPhone 13 After iOS Update? Here’s How to Fix It

If Facebook keeps crashing on your iPhone 13 after installing an iOS update (like iOS 15.2.1), you’re not alone. This is a common issue that often happens after major iOS updates — especially when apps like Facebook haven’t been updated to match the new system.

Below are several practical ways to fix the problem and get Facebook running smoothly again.


Check Your iPhone’s Storage First

Before diving into the fixes, make sure your iPhone isn’t running low on storage:

  • Go to Settings > General > iPhone Storage
  • If available space is below 2GB, try deleting old files, apps, or offloading unused apps
  • Move large files to iCloud or an external backup if needed

Low storage can cause all kinds of app instability, including crashes.


1. Force Quit Facebook and Other Background Apps

Sometimes apps left running during an update can glitch afterward. Here’s how to force close them:

  • Swipe up from the bottom of the screen and pause in the middle to open the App Switcher
  • Find Facebook, then swipe up on its preview to close it
  • Do the same for all other open apps
  • Reopen Facebook and see if it still crashes

2. Restart Your iPhone (Soft Reset)

A quick reboot clears out temporary glitches that could be breaking app behavior:

  • Press and hold the Side button + Volume Up or Down until you see the power slider
  • Drag the slider to turn off your iPhone
  • After 30 seconds, press and hold the Side button again until the Apple logo appears

After restarting, open Facebook again and check if it’s working.


3. Update the Facebook App

If Facebook isn’t updated to support the latest iOS version, crashes are likely:

  • Long-press the App Store icon and tap Updates
  • Tap Update next to Facebook (or Update All to cover everything)
  • Once done, restart your iPhone to refresh app behavior

4. Refresh Your Wi-Fi Connection

If Facebook crashes are tied to network issues, especially on an unstable Wi-Fi connection, try this:

  • Go to Settings > Wi-Fi and toggle it Off, wait a few seconds, then On again
  • Or do the Airplane Mode trick:
    • Settings > Airplane Mode > On
    • Restart your iPhone
    • Go back and toggle Airplane Mode Off
  • If that doesn’t help, forget the Wi-Fi network and reconnect:
    • Settings > Wi-Fi > Tap the “i” next to your network > Forget This Network
    • Reconnect by entering your password

5. Offload the Facebook App

This removes the app but keeps its data, giving it a fresh install without losing your account info:

  • Go to Settings > General > iPhone Storage
  • Scroll and tap Facebook
  • Tap Offload App, then confirm
  • After offloading, tap Reinstall App

This is a great way to refresh the app without wiping your saved data.


6. Delete and Reinstall Facebook

If offloading doesn’t cut it, do a full reinstall:

  • Long-press the Facebook app icon and choose Remove App > Delete App
  • Open the App Store, search for Facebook, and reinstall it

This fully clears the app and its data, which helps if the crash is due to deeper corruption.


7. Reset All Settings

Sometimes, iOS updates override system settings and cause app instability. Resetting all settings won’t delete your data but will restore system defaults:

  • Go to Settings > General > Transfer or Reset iPhone > Reset
  • Tap Reset All Settings
  • Enter your passcode, then confirm

This will reset network settings, privacy permissions, and more — without touching your photos or files.


8. Check if Facebook’s Servers Are Down

Sometimes the issue isn’t on your end. Use a site like Downdetector to check if Facebook is experiencing outages. If so, there’s nothing to fix — just wait it out or use the browser version in the meantime.


9. Report the Bug to Apple

If none of these work and the problem started after an iOS update, report it:

  • Visit Apple Support
  • Explain the issue, what you’ve tried, and that it started after updating iOS

Apple may include a fix in an upcoming software patch.
