How to troubleshoot Galaxy J2 Pro 2018 with Facebook that keeps crashing

Before you begin troubleshooting, verify and ensure that your phone is connected to Wi-Fi internet and is not having some network connectivity issues like intermittent connection or network connectivity drops. Facebook requires Internet to work properly. This means the need to deal with Internet problems first (if they exist) in order to get Facebook and other online apps back up and running smoothly again. If your device is having a good and stable Internet connection and yet Facebook app still doesn’t work steady or keeps crashing, then you may go ahead and begin to troubleshoot the app and your phone system itself. Here are your options:

First solution: Force close Facebook and background apps.

Background apps are comprised of apps that are recently opened and running in the background. While keeping these apps open helps when multitasking, they can make the device slow down, drain much power, and misbehave especially when any of these apps gets corrupted. If this happens, the phone system or other apps like Facebook might adversely be affected. To prevent this from happening, forcing background apps can help. Here’s how to force close background apps on your Galaxy J2 Pro 2018:

  1. Tap on the Apps icon from the Home screen.
  2. Tap Smart Manager.
  3. Tap to select RAM option.
  4. Finally, tap End All to close all background apps including Facebook.

Aside from quitting errant background apps, this will also instigate RAM cleaning. Deleting unnecessary data including cached, residual and advertisement files from certain apps and/or phone system can also help.

Second solution: Restart your phone (soft reset).

A soft reset or device restart the simplest possible solution you can try on if the prior method failed to fix the issue. It’s the easiest way to reboot the operating system and reload all services. Any minor glitches affecting certain apps like Facebook are cleared, thus random errors are typically resolved. All your personal data, files and downloaded apps saved on your device will remain intact or unchanged.

  • To restart (soft reset) your Samsung Galaxy J2 Pro (2018), press and hold the Power button and the Volume Down button on the side until the phone restarts.

Wait until your device completely reboots and then try to launch and use Facebook again to see if the problem is resolved. If the app still crashes, then move on to the next possible solution.

Third solution: Clear cache and data on Facebook app.

Clearing cache and data from the Facebook app can be the key to fixing the problem if corrupted cached files and data are to blame. It also helps make the app performing faster and smoother. Here’s how to clear app cache and data on your Galaxy J2 Pro (2018):

  1. Tap Apps from the Home screen.
  2. Navigate to Settings-> Apps menu or Settings-> Apps & Notifications-> App info, for devices running on Oreo operating system.
  3. Tap Facebook.
  4. Tap Storage.
  5. Tap Clear Cache. This will wipe cached files from the Facebook app.
  6. If you want to clear data stored on the app like logins, saved games, and other Facebook data, tap Clear Data too.
  7. Tap OK to confirm.

If you cleared the data, you will need to sign in to your Facebook account to use the app again. When the Facebook app cache and data clearing is done, restart your phone to refresh the operating system and apply the recent changes.

Fourth solution: Install app updates, if available.

Updates can bring either good or bad outputs. But generally, updates are pushed to optimize apps and enhance system functions. They also bring in security features or fix patches to get rid of any bugs that might have caused the app to malfunction or destabilize. If you haven’t set your device to auto-install updates, then you will need to check and install updates manually. Here’s how to update Facebook app on your Galaxy J2 Pro 2018:

  1. Go to Play Store and then click Menu.
  2. Tap on My Apps & Games.
  3. Tap to select Facebook app.
  4. Click on the Update button.

Reboot your device (soft reset) after the update is successfully installed. This will make sure that all new changes from the recent update are properly implemented.

Fifth solution: Uninstall and reinstall Facebook app on your phone.

Uninstalling the problematic Facebook app might be necessary if the app itself gets totally corrupted and unfixable. After deleting the app, you can download and install the latest Facebook app version that is free from flaws and working properly. Here’s how to uninstall Facebook on your Galaxy J2 Pro 2018:

  1. Go to Play Store and then click Menu.
  2. Tap on My Apps & Games.
