Facebook mobile not working on iPhone can look like a frozen feed, a crash on launch, missing photos, broken links, no notifications, or a login screen that will not move. The fastest fix depends on whether the problem is the connection, the app, iPhone settings, or the Facebook account itself. Start with the checks that rule out network and app glitches, then move to updates, permissions, reinstalling, and account recovery.
1. Prove the connection works first
Use this first when Facebook will not load, photos stay blank, or the feed keeps spinning.
- Open Settings, tap Wi-Fi, and join a known working Wi-Fi network. If that network is yours and Wi-Fi still fails, restart the router or modem, restart the iPhone, and open Facebook again.
- If Facebook works on Wi-Fi but not mobile data, open Settings, tap Cellular, turn on Cellular Data, scroll to Facebook, and turn it on. On an iPhone with multiple SIMs, go to Settings > Cellular > Cellular Data, then choose the line used for data.
- When the iPhone shows No Service, SOS, Searching, or unstable mobile data, open Settings, turn on Airplane Mode for at least 15 seconds, then turn Airplane Mode off. You can also use the Airplane Mode button in Control Center.
2. Close Facebook only when it freezes
- 1.On iPhone X and later, swipe up from the bottom of the Home Screen and pause in the middle.
- 2.Swipe left or right until you find Facebook.
- 3.Swipe up on the Facebook preview.
- 4.Open Facebook again from the Home Screen or App Library.
Apple says to close an app only when it is unresponsive, so use this for crashes, frozen screens, and stuck loading states. On an iPhone with a Home button, double-click the Home button, swipe up on Facebook, then reopen Facebook.
If the app still fails, restart the iPhone. On iPhone X, iPhone 11, iPhone 12, iPhone 13, or later, press and hold either volume button and the side button until the power-off slider appears, drag the slider, wait 30 seconds, then press and hold the side button until the Apple logo appears. On iPhone 6, iPhone 7, iPhone 8, or iPhone SE 2nd or 3rd generation, press and hold the side button until the slider appears, drag it, wait 30 seconds, then press and hold the side button again.
3. Update Facebook and iOS together
A broken Facebook build or unsupported iOS version stops normal fixes from landing. The current App Store listing for Facebook requires iOS or iPadOS 15.1 or later.
- 1.Open the App Store.
- 2.Tap the My Account button or your photo.
- 3.Go to App Updates.
- 4.Tap Update next to Facebook, or tap Update All.
Then update iOS: open Settings, tap General, tap Software Update, tap Download and Install when an update is available, and follow the onscreen instructions.
Turn on future app updates while you are there: Settings > Apps > App Store > App Updates.
4. Remove data limits that slow Facebook down
- For cellular, open Settings, tap Cellular, then tap Cellular Data Options. On an LTE/4G iPhone, turn off Low Data Mode there. On a 5G iPhone, tap Data Mode, then turn off Low Data Mode or choose a non-Low Data mode. With Dual SIM, open Settings > Cellular or Mobile Data, tap your number, then turn off Low Data Mode.
- For Wi-Fi, open Settings, tap Wi-Fi, tap the Info button next to the connected network, then turn off Low Data Mode.
Low Data Mode reduces background network use and streaming quality. Turn it off when Facebook loads slowly, media will not autoplay, or feed content does not refresh normally.
If notifications or feed content refresh only after you open Facebook, check background refresh. Go to Settings > General > Background App Refresh > Background App Refresh, then choose Wi-Fi or Wi-Fi & Cellular Data. Return to the app list and turn on Facebook when it appears.
5. Restore the permission Facebook needs
When one feature fails and the rest of Facebook opens normally, fix the matching iPhone permission instead of reinstalling the app.
Open Settings, tap Privacy & Security, then tap the feature that matches the failure: Camera, Microphone, Photos, Location Services, Bluetooth, Local Network, or Contacts. Turn on Facebook access or adjust the allowed access level.
You can also open Settings, scroll down or tap Apps, tap Facebook, and adjust the permissions listed there. For missing alerts, use the notification path instead: Settings > Notifications > Facebook > Allow Notifications, then choose alert style, sounds, badges, and other notification behavior.
6. Clear Facebook browser data when links break
- 1.Open Facebook.
- 2.Tap Menu.
- 3.Tap Settings & privacy, then tap Settings.
- 4.Open Browser or Browser settings.
- 5.Next to Cookies and cache, tap Clear.
- 6.Tap Clear again to confirm.
This fix is for Facebook's in-app browser, not the whole iPhone app cache. Use it when links opened inside Facebook will not load or behave incorrectly.
To separate app trouble from Facebook web trouble, open Safari, go to m.facebook.com or www.facebook.com, and log in. If Facebook works in Safari but not in the app, update or reinstall the app. If Facebook fails in both, work on network, login, account, or Meta status checks.
For Facebook problems only in Safari, refresh the page, close and reopen the page, clear browser cache from browser settings, or try a different browser. To remove Safari website data, go to Settings > Apps > Safari > Advanced > Website Data > Remove All Website Data > Remove Now. If Facebook web content is missing, go to Settings > Apps > Safari > Extensions and turn off the content blocker, or temporarily turn off Block Pop-ups in Safari settings while testing.
7. Reinstall Facebook after the faster fixes fail
Reinstall when Facebook crashes on launch, freezes repeatedly, or stays broken while the mobile website works. Deleting Facebook removes the local app and related data from the iPhone.
- 1.Touch and hold Facebook.
- 2.Tap Remove App.
- 3.Tap Delete App.
- 4.Tap Delete.
- 5.Restart the iPhone.
- 6.Open the App Store.
- 7.Search for Facebook by Meta Platforms, Inc.
- 8.Tap Get or the Redownload button.
If Facebook was offloaded or removed earlier, redownload it from your App Store history. Open the App Store, tap the My Account button or your photo, open Apps & Purchase History, tap Your Apps, tap Not on this device, find Facebook, and tap the Redownload button.
If the update or reinstall fails because storage is tight, free space by offloading unused apps. Go to Settings > General > iPhone Storage, then tap Enable next to Offload Unused Apps. You can also use Settings > Apps > App Store > Offload Unused Apps.
8. Fix account and restriction blocks
- If Facebook opens but you cannot log in, start account recovery on a device and browser you have used before. Open facebook.com/login/identify, enter an email address, mobile phone number, full name, or username, then follow the instructions. From the app login screen, tap Forgot password?, enter your email, mobile number, full name, or username, tap Search, and follow the instructions.
- If login stops at two-factor authentication, use a saved recovery login code. If you are already logged in on another device, open Facebook, tap Menu, tap Settings & privacy, tap Settings, open Accounts Center, tap Password and security, tap Two-factor authentication, choose the Facebook account, then manage methods or get recovery codes. For Facebook's SMS one-time password option, text otp to 32665; Facebook sends the password only when the mobile number is linked and the feature is available for the carrier and region.
- If the account was taken over, open facebook.com/hacked from a device you have used to log in before and follow the onscreen prompts. For login or platform failures that affect more than one device, check Meta's Facebook Login status page and Meta Status before reinstalling again.
Not every Facebook problem is an app problem.
Screen Time can block Facebook, app installs, app deletion, and Facebook web access. Go to Settings > Screen Time > App Limits, then remove or adjust any limit affecting Facebook or Social Networking. For installs and deletes, go to Settings > Screen Time > Content & Privacy Restrictions > iTunes & App Store Purchases, then allow Installing Apps and Deleting Apps. For web blocks, open App Store, Media, Web, & Games, tap Web Content, remove facebook.com from Never Allow, or adjust the restriction.
For a school, work, child, or managed iPhone, open Settings, tap General, then tap VPN & Device Management. If Facebook, Safari, the App Store, VPN, DNS, app installation, app deletion, or web access is restricted and you cannot change it, contact the device administrator or Family Sharing organizer.
9. Reset only after narrowing the problem
Use resets at the end, because they affect more than Facebook. When many apps have network trouble, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This removes saved Wi-Fi networks and passwords, cellular settings, VPN settings, and APN settings used before.
If the iPhone itself is frozen and will not respond normally, force restart it. On iPhone 8 or later, including iPhone SE 2nd or 3rd generation, press and quickly release volume up, press and quickly release volume down, then press and hold the side button until the Apple logo appears. On iPhone 7 or 7 Plus, press and hold the side button and volume down until the Apple logo appears. On iPhone 6s or earlier, including iPhone SE 1st generation, press and hold the Home button and the top or side button until the Apple logo appears.
Reset all settings only after narrower fixes fail and Facebook is not the only affected app. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This returns settings to defaults without erasing content; back up first if you need to restore settings later.
When Facebook opens and you can reproduce the broken feature, report it to Meta. Go back to the screen where the problem happened, shake the iPhone, tap Report problem, choose Include or Don't include, describe what happened, and send the report. You can also use Menu > Help & support > Report a problem > Continue to report a problem, then follow the onscreen instructions.
Skip outdated iPhone advice. Current Apple and Meta guidance does not provide a generic Facebook app cache-clear button in iPhone settings. Use Facebook's in-app browser Cookies and cache control for link problems, delete and reinstall the official Facebook app for local app data problems, or use m.facebook.com. Facebook Lite and old standalone Facebook apps are not current iPhone repair paths in the verified research.
Frequently Asked Questions
Why does Facebook work on Wi-Fi but not cellular on my iPhone?
Facebook is blocked from mobile data or the cellular connection needs to reconnect. Go to Settings > Cellular, turn on Cellular Data, enable Facebook in the app list, then toggle Airplane Mode on for at least 15 seconds and off again.
Can I clear the Facebook app cache on iPhone?
No generic iPhone setting clears the full Facebook app cache. Clear Facebook's in-app browser Cookies and cache for link problems, or delete and reinstall Facebook to remove the local app and related data.
Why are Facebook photos, camera, microphone, or location features not working?
The matching iPhone permission is blocked. Go to Settings > Privacy & Security, open Photos, Camera, Microphone, Location Services, or the feature that matches the problem, then allow Facebook access.
What should I do if Facebook opens but I cannot log in?
Use Facebook account recovery from a device and browser you have used before. Go to facebook.com/login/identify, or tap Forgot password? on the app login screen and search by email, phone, full name, or username.
Should I install Facebook Lite on iPhone?
No. The verified iPhone repair paths are the official Facebook app from the App Store and Facebook in a mobile browser at m.facebook.com.
