Facebook Troubleshooting for Android and iPhone
Facebook problems can come from the app, internet connection, phone settings, account restrictions, or Facebook’s online service.
The first step is therefore to identify exactly what is failing.
If Facebook will not load at all, test another website or application to determine whether the internet connection is working. If Facebook opens but one feature such as Reels, comments, notifications, or Marketplace does not work, troubleshoot that feature rather than treating the entire application as broken.
The guides in this category cover common Facebook problems including notifications, comments, Reels, Marketplace, loading problems, and general Facebook app failures.
A useful diagnostic comparison is to test Facebook in the mobile application and browser, switch between Wi-Fi and mobile data, and determine whether the problem occurs on another device.
If a problem follows the same account across multiple devices, repeatedly clearing the app or reinstalling it may not address an account or service-side issue.
Before clearing app data or reinstalling Facebook, make sure you know your login details and understand what local application information may be removed.
Use the guides below to find the Facebook feature or symptom that most closely matches your problem.
