iOS 18.1.1 Update Causes App Malfunctions

The iOS 18.1.1 update, intended to bring bug fixes and improvements, has introduced a significant issue: app malfunctions. Users report various problems, from select apps not working to most apps malfunctioning, rendering their iPhones unusable. This issue affects a wide range of users and impacts app functionality across the board.

Fixing App Issues on iOS 18.1.1

Several potential solutions can address this problem. Start with simpler fixes and proceed to more drastic measures if necessary.

  1. Update Apps: Ensure all apps are updated to the latest versions through the App Store. App incompatibility with iOS 18.1.1 is a possible culprit. Check for updates by tapping your profile picture in the App Store and selecting "Apps."
  2. Force Restart iPhone: Refresh running services by force restarting your iPhone. This can resolve bugs preventing apps from opening. Quickly press and release the Volume Up button, then the Volume Down button. Finally, press and hold the Side button until the Apple logo appears.
  3. Reinstall Apps: Reinstalling apps can resolve deeper issues. Remove the malfunctioning app and reinstall it from the App Store. This ensures the latest version is installed and can fix underlying software conflicts.
  4. Disable VPN: VPNs can interfere with app functionality, especially banking and internet-dependent apps. Disable your VPN or delete the VPN profile in Settings > General > VPN & Device Management > VPN.
  5. Remove Google Chrome: Some users report that removing Google Chrome as the default browser or entirely deleting it resolves the issue. The reason is unclear, but it might be due to compatibility problems between Chrome and iOS 18.1.1. To change the default browser, go to Settings > Apps > Safari > Default Browser App.
  6. Factory Reset (Last Resort): If all else fails, factory reset your iPhone after backing up your data. This can resolve persistent bugs or conflicts. Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Remember to restore from your backup after the reset.
