Facebook not opening on a Samsung phone: a step-by-step One UI fix

If Facebook will not open on your Samsung phone, clear the app’s cache first, then update it. On some Galaxy models Facebook comes preinstalled; it cannot be removed, but its updates can be uninstalled and installed again. If the app is put to sleep in battery settings, notifications and opening can be affected.

Key points
  • Clear the app’s cache first.
  • Update the app from the Play Store or Galaxy Store.
  • On a preinstalled app, uninstall updates and reinstall them.
  • Check sleeping apps in the battery settings.
  • Clearing data signs you out; know your password.

01Steps in One UI

  1. Clear the cache. Settings › Apps › Facebook › Storage › Clear cache.
  2. Update. Update the app from the Play Store or Galaxy Store.
  3. Force stop. On the same screen, tap Force stop and reopen the app.
  4. Clear data. If it continues, Clear data returns the app to its first state; you are signed out.

Menu names can differ slightly by One UI version.

02A preinstalled app

On some Galaxy models Facebook comes with the system and cannot be removed completely. In that case you can uninstall updates from the three-dot menu on the app page, then update it again from the store. Disabling and re-enabling it can also help.

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
