How To Fix Facebook Keeps Crashing iPhone 7 Plus after iOS 11.3.1 Update

First solution: Clear Facebook and other background apps then restart

Apps can go rogue at some point due to many factors, including random glitches and faulty updates. For first instances, a Facebook app that’s crashing can denote that Facebook is glitching. To fix the problem, you will need to clear and refresh Facebook app. Here’s how:

  1. Press the Home button twice quickly. Doing so will open a list of recently used apps on the screen.
  2. Swipe up on Facebook app to clear it.
  3. If you see other backgrounds apps, then clear them as well to prevent any of them from causing conflict while using Facebook.

There is a tendency for background apps to crash or get corrupted and when this happens, other apps including Facebook can be affected and therefore, misbehave.

Second solution: Refresh your phone’s Wi-Fi Internet connection

Facebook is a server-based app and requires an active Internet connection to work as intended. If your device is experiencing network connectivity issues, then server-based apps can also become shaky because its connection to the server is intermittent or unstable. In this fix, you will need to fix network connectivity issue on your iPhone first for Facebook to work properly again. That said, refresh your phone’s internet connection by turning Wi-Fi off and then back on.

To do so, head over to Settings-> Wi-Fi menu and then tap the Wi-Fi switch to turn the feature off. After a few seconds, tap the switch again to turn Wi-Fi back on.

Restart your iPhone afterwards, and then launch Facebook and see if it is already working steady.

Third solution: Update Facebook and other apps, if applicable

Developers of Facebook app must make sure that the app is always optimized and performing at its best. This is just right given the millions of users of the app. A typical way to maintain their app is by pushing periodic updates. These updates bring in new features and security enhancements to keep the app free from bugs and flaws. Thus, installing app updates is highly recommended. If you haven’t set your device to install updates automatically, then you need to manually check and install available app updates including Facebook. Here’s how:

  1. Tap the Apps Store icon from the Home screen. Doing so opens the App Store main screen.
  2. Tap the Updates icon at the bottom right side of the screen. A list of apps with pending updates will then show up.
  3. Tap the Update button next to Facebook to update the app.
  4. If multiple app updates are available, tap the Update All button to update all apps at once.

Restart your iPhone when all apps have finished updating. After the reboot, try to open Facebook again and see if the problem is fixed.

Fourth solution: Reset all settings on your iPhone 7 Plus

The way your iPhone system is configured can affect certain apps, particularly on how they work. For example, you can configure your device to prevent certain apps from auto-updating as well as grant or prevent system access for an application. Having said that, it is possible that how Facebook app behaves has something to do with how pertinent settings are configured on your device. This is likely the underlying cause if Facebook app started to act weird or crash after modifying some settings on your iPhone. To rule this out, you can revert these settings back to their previous configuration. However, if it isn’t possible for you to identify which settings or options to change, then you can just reset all settings on your iPhone instead. After resetting all settings, you can enable necessary features or options individually and based on your preferences.

To reset all settings on your iPhone 7 Plus, go to Settings-> General-> Reset menu. Then tap to select Reset all settings option. If prompted, enter your device passcode to continue and then confirm system settings reset.

This won’t affect any data stored on your iPhone’s internal memory. After the reset, restart your iPhone to apply the changes. Default system settings will then be implemented. Enable all necessary features you want to use including Wi-Fi and Bluetooth.

Fifth solution: Uninstall Facebook app, restart your iPhone then reinstall Facebook

You may have to consider deleting the app if you’ve already exhausted every possible means to fix the problem on your end but still ended up having the same problem. The app might have been totally corrupted and should therefore be reinstalled. Here’s what to do then:

  1. Tap and hold on any icon from the Home screen and wait until the icons start to wiggle.
  2. Tap the X in the corner of Facebook icon to uninstall the app.
  3. Tap Delete to confirm action.

Wait until Facebook is successfully removed, restart your phone then reinstall Facebook with these steps:

  1. Tap to open the App Store.
  2. Enter Facebook in the App Store search field.
  3. Select Facebook app from the search result.
  4. Verify and ensure that the selected Facebook app meets the minimum system requirements to run on your iPhone 7 Plus. Otherwise, look for a compatible Facebook app version.
  5. Tap the Cloud icon or Get button to start downloading and installing Facebook on your iPhone.
  6. If prompted, enter your Apple ID password to continue.

Wait until the app is successfully installed, restart your iPhone and then launch the Facebook app you recently installed. Test and see if it is already working steady.
