Troubleshooting iPhone 8 with Facebook app that keeps lagging, freezing and crashing


Applications-related problems like this are not really that complicated to fix. In fact, you can get this problem sorted out in no time if only you’re willing to do some simple troubleshooting procedures. Try to follow our step-by-step guide below to try and get Facebook to work properly.

First solution: Quit all background apps on your iPhone 8.

All the apps you’ve previously opened will stay running in the background unless you quit them from the apps drawer. These apps are in standby mode so that the next time you’ll use them, they’ll load quickly. But there is a higher chance that any of these background apps can crash and when that happens, other apps and processes will might as well be affected, adversely. To eliminate background apps from the culprits, try quitting them all. Here’s how to quit background apps on your iPhone 8:

  1. Double-press the Home button to view all apps you recently used.
  2. Swipe right or left to locate the Facebook app from the Apps previews.
  3. Swipe up on the Facebook app preview to close it.
  4. Or you can just close all apps instead.

After you quit all your background apps, restart your iPhone 8. A restart can help clear out any minor glitches caused by corrupted iOS data or any app.

To do so, press and hold the Side button (Power) until the Slide to Power Off screen appears. Drag the slider to turn off the device completely. Wait for about 30 seconds, then press the Side button again until the Apple logo appears.

That should give your iPhone 8 a fresh start. Now launch the Facebook app and see if the problem is fixed and that the app is already working as intended.

Second solution: Clear cache on Facebook app.

Apps normally store cache files based on previous activity logs. The more often you used the app, the more cache it stores. The same goes with your Facebook app. In fact, Facebook is probably the mostly used app on your iPhone. The thing is, cache files can crash or become corrupted. And when this happens, the entire operation of the application will likely be affected. This is when your Facebook app starts to misbehave. To eliminate this from the possibilities, clearing the Facebook app cache can help. Here’s how to clear cache on Facebook on your iPhone 8:

  1. Open the Facebook app on your iPhone.
  2. For as long as the app is working, tap the More button at the bottom part.
  3. Tap Settings.
  4. Then select Account settings from the drop-down list.
  5. Tap Browser to open the Browser Settings page.
  6. Tap the option to Clear Data.

If this couldn’t be done since Facebook suddenly crashes, then you can just try other options instead.

Third solution: Update iOS to the latest version available.

Sometimes, new iOS updates contain a fix patch that will help stabilize iOS apps including Facebook. So if you haven’t already, check for any available update for your iPhone 8 then try to install it on your device. But if you have done it already but caused you this problem instead, then you can just skip his method then try the rest of the applicable solutions.

  1. To check for available software update on your iPhone 8, go to Settings-> General-> Software Update.
  2. If an update is available, you’ll see an update notification.

Be sure to read the details in order to know what the new update brings and what it does to your device. Then backup your iPhone 8 data and proceed with the iOS download and Installation process.

Fourth solution: Update Facebook app.

Just like iOS updates, Facebook also has its own share of periodic rollouts. These updates also contain software enhancements and fixes to existing bugs that have been known to affect or hinder the app’s overall performance. Should you wish to try this solution, here’s how to update iOS Facebook app:

  1. Tap the App Store icon from the Home screen.
  2. Tap the Updates icon at the bottom right.
  3. Locate Facebook then tap the Update button next to it.
  4. If you see any other updates for your other apps, tap the Update All button instead.

Restart your iPhone 8 then try to launch the Facebook app again to see if it’s now able to work as intended.

Sixth solution: Remove and reinstall Facebook app.

Your next option if the problem persists after the prior solutions is to uninstall Facebook then install it again on your iPhone 8. If the Facebook app gets corrupted and is no longer able to work properly, there is no point of keeping it. Uninstalling the app can be a potential fix as it will clear out the device from any bug caused by the app in the first place. Reinstall the app afterwards. Here’s how it’s done:

  1. Tap and hold on any icon on the Home screen.
  2. When you see the icons starting to wiggle, tap the X in the corner of the Facebook app.
  3. Then tap Delete.

The app is now uninstalled. Restart your iPhone then go back to the App Store, locate Facebook app for iOS then download and install the app on your device.

Seventh solution: Reset all settings on your iPhone 8.

Some Facebook problems are triggered by network issues like unstable network connections. When the Internet is unstable or keeps on dropping, Facebook won’t be able to establish a stable connection with the server and therefore ends up showing symptoms like recurrent errors, lags, and sudden crashes. To fix any problem inflicted by network glitches on your iPhone 8, performing a network settings reset can help. Here’s how it’s done:

  1. Tap Settings.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select the option to Reset Network Settings.
  5. If prompted, enter the device passcode to continue.
  6. Tap the option to confirm network settings reset.

All data connections are reset and restored back to its original settings. Set up and connect to your wireless network then try to check if Facebook app is working fine already.

Last option: Restore your iPhone through iTunes.

If none of the prior given solutions is able to fix the problem and that you still end up having an unstable Facebook app on your iPhone 8, then it’s either you’ll give up the app (uninstall) or do some tedious workaround which involves backing up of your personal information and important data on your device then conduct a full iOS restore. You may opt to go for a factory reset through iPhone 8 settings menu or use iTunes on a computer. But then again, the entire reset can take time so it’s up to you to decide.

You can do a master reset or factory reset through your iPhone 8 settings menu. Here’s how:

Backup your iPhone data. All your data will be erased in the process so you’ll need to have them backed up beforehand for safekeeping.

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Tap Reset.
  4. Select the option to Erase All Content and Settings.

Note: You may select the option to Reset All Settings instead if you don’t want your data to be erased in the process.

  1. If prompted, enter your device passcode to continue.
  2. Tap the option to confirm reset.

If your iPhone 8 is not responding as the Facebook app crashes or freezes, you can do an iOS restore using iTunes. You will need to use a computer with the latest version of iTunes software installed in order to proceed. Once you have the computer ready, connect your iPhone to the computer using the supplied USB connector or Lightning cable. Then wait for iTunes to recognize your iPhone and follow the onscreen instructions to restore iOS on your iPhone 8.

What to do if Facebook still crashes or freezes on your iPhone 8?

You may attempt to reach Facebook support to report the problem especially if it started after installing a new update to Facebook app. You may not be able to get a prompt reply but at least you have informed them of the problem, which they’re obliged to fix.

Meanwhile, if the Facebook app started to act weird following a new iOS update installation, contact Apple Support or your carrier to escalate the issue and have them tagged it among other post-update issues to be addressed in the next fix patch. Post-update issues are generally addressed by the next firmware update containing an official fix patch from Apple.
