Galaxy S8 Facebook app only works after deleting app data, keeps crashing

Hello and welcome! Today’s article answers some Facebook issues that some #GalaxyS8 owners have encountered during the past few days. We hope this short guide will help those having issues with this app.

Problem #1: Galaxy S8 Facebook app won’t open using a certain account

I cannot open my Facebook app using my account. However i can open it if i use another account which is my son’s account on my phone. How can i solve this issue when i cannot even uninstall the app and already followed the directions placed? — Moua

Solution: Hi Moua. If you are unable to open Facebook app using a particular account only, it’s very possible that the issue is account-related and not with the phone or app. You should settle whatever issue your own Facebook account has in order to fix the problem. We suggest that you sign in to your Facebook account using a second device like another phone or computer. If you have trouble signing in, or if you get any error after you sign in to your account, you can then do a quick Google search about that it to see what it means. Or, you can visit the Facebook Help Page for more assistance. Whatever account issue that causes your Facebook app to crash can only be fixed by Facebook as well. Try to gather as many information as you can about the problem and report the bug.

To ensure that you also take care of your Facebook app, make sure that you clear its data by doing these steps:


  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your app.
  6. Tap Storage.
  7. Tap Clear Cache button.
  8. Restart your S8 and check for the problem.

Problem #2: Galaxy S8 Facebook app only works after deleting app data

I have followed all the steps given in your blog but still Facebook app is not working. I have rebooted my phone as well. The only way I can open facebook is by going to app menu and deleting all the data and cache from there. Then it will open for once and after closing the app it will not open again. Is it some problem with my phone and app needs some update? Kindly advise. — Omer

Solution: Hi Omer. At this time, we are yet trying to figure out if there’s an on-going issue with Facebook app or with Facebook service in general. We can confirm that our own Galaxy S7, S8 and S9 devices don’t have any problems with Facebook so there may be a bug that only affects certain phones or models.

Right now, below are the troubleshooting steps that you can try.

Install app updates

Make sure that all apps, including Facebook itself, are up-to-date. Many app bugs are fixed by simply installing app updates. Remember, apps don’t work in isolation. An incompatible app can affect the operating system or other apps so try to have all your apps updated to lessen the chances of incompatibility issues.

To check for updates for apps, you can use the Play Store app. Here’s how to do that:

  1. Open Play Store app.
  2. Tap More settings at the upper right.
  3. Tap My apps & games.
  4. Tap UPDATE ALL button if you have multiple updates.
  5. Make sure to always keep all apps up-to-date in order to minimize the chance of another app causing problems in the system.

Update Android

If you have pending Android updates at this time, or if you haven’t updated the system for a long time, it’s time to check if there’s any available update for you. Android devices are set to automatically download and install over-the-air updates by default. If you changed this default behavior before, make sure to check for Android updates under Settings > Software update.

Switch network mode

If you’ve been using one particular type of internet connection (wifi or mobile data) all this time, you should consider switching to another one to see if it makes any difference. So, for example, if you’ve been using mobile data for a while now, try to connect to a wifi network and see how Facebook app works. Or, if you’ve been relying on wifi all the time, try to see what happens when you use mobile data when using Facebook app.

Clear network settings

Facebook works only when you’re online so a lot of its bugs are network-related. To see if the cause of the problem lies on your phone’s current network setup, consider wiping its network settings by doing these steps:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset Network settings.
  5. Tap RESET SETTINGS button to confirm.
  6. Restart your S9 and check for the problem.

Uninstall or reinstall Facebook

If wiping the Facebook cache and data don’t fix the issue, you should also consider re-installing it. Just delete the app from your phone and reinstall it from the Play Store. If your Facebook app came with the operating system (pre-installed), you can disable it to revert it back to its default settings. Here’s how:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your app.
  6. Tap DISABLE.
  7. Tap OK to confirm.

Safe Mode (If facebook is pre-installed)

Another good thing that you can do if your Facebook app is preinstalled is by booting it to safe mode. In this mode, no third party apps will be allowed to run. So, if Facebook app works fine in this mode but becomes problematic once you restart your S8, that’s a clear case of a bad app situation.

To boot your S9 Plus to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Open Facebook app and see how it works. To know if there’s a difference, use Facebook app for a few hours.

To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S8 is still problematic, repeat steps 1-4.

Uninstall Facebook update

App updates may sometimes contain imperfect improvements that might lead to bugs. If your Facebook problem started after installing an update from the Play Store, you can uninstall it by doing the following:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your app.
  6. Tap the three-dot icon at the upper right.
  7. Tap Uninstall updates.

Factory reset

If the issue is still happening at this time, you should consider wiping your phone by doing a factory reset. This will help ensure that you’ve covered everything before eventually reporting the trouble to Facebook developer team. Remember, factory reset will wipe all user data so be sure to back them up ahead of time.

Once you’ve created a backup, follow these steps to factory reset your S9:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Try using beta version

Some users were able to work around their unexplained Facebook crashes by uninstalling the final version and using the beta version instead. Beta versions of apps are usually less stable but they also allow a user to use the most recent features and improvements. If you want to become a beta tester, you can follow the instructions in this page.

Report the Facebook bug

If all else fail, you can report the problem to Facebook by using this link.

Problem #3: Galaxy S8 Facebook app keeps crashing

Followed your directions on the FB app crashing all the time. 1st, you really should warn people that this is a COMPLETE reset. I’m in the midst of restoring everything from the SCloud-very worrisome as I’m not sure everything I had previously was sent to the SCloud. and 2) I can’t tell you yet if your directions/advice fixed the FB app it’s all taking so long to retrieve my content. I’m 58 so I wouldn’t know that a cache clear/data reset would wipe my phone! Thanks. — Barclay 

Solution: Hi Barclay. The only troubleshooting step that will wipe your phone clean and restore it to its factory state is factory reset and we usually remind our readers to back everything up before doing it. If we failed to put that reminder in one of our articles, we apologize. Kindly give us the link of that article so we can update it.

As far as clearing of the cache is concerned, it won’t touch your data at all! Clearing the cache partition or an app cache will only deal with the temporary set of files and other stuff. Your files like photos, videos, documents, etc. should still be there after wiping whatever type of cache.

If our suggestions in this article and previous one that you check won’t help at all, contact Facebook for more assistance. Remember, we don’t work for Facebook so we don’t have all the answers for every bug that shows up.
