How to fix apps not working on iPhone after iOS 17 update issue

1. Check your internet connection

Most iOS apps require an active internet connection to function. You will generally see an error message when you open an app without connectivity. Check the phone’s Wi-Fi and cellular data settings to ensure you’re connected.

2. Force quit and reopen the app

You can try force-quitting an app if it’s not working properly. Bring up the App Switcher by swiping down from the bottom of the screen. Find the app that’s not working, and swipe up to close it. Then, head to your **Home Screen **to relaunch the app.

3. Restart your iPhone

Restarting iPhone is a go-to troubleshooting step when apps not working after iOS 17 update. Here’s how:

  1. Turn off your iPhone:
    • For models with Face ID, press and hold the side button and a volume button, then drag the slider to the right.
    • For models without Face ID, press and hold the power button until the slider appears, then drag the slider to the right.
    • With any model, you can also go to Settings > General > Shut Down.
  2. _Turn on your iPhone: _Hold down the side button until the Apple logo appears.

4. Check for Software update

Ensure that your iPhone is updated to the latest iOS 17 version, especially if a previous update caused the apps to stop working. To check for the newest iOS 17 update, go to Settings > General > Software update.

5. Update your apps

Developers often release app updates to fix bugs and patch other performance issues. If your apps stopped working on your iPhone after iOS 17 update, updating them may just be the trick to solving the problem.

To quickly check whether a specific app has an update, head to the App Store’s **Search **tab to find the app. If an update is available, you’ll see an **Update **button instead of the usual **Open **button. Tap on it to update the app.

6. Check if the app is down

If an app isn’t loading, check whether it’s an issue on just your phone or for everyone. Look at Apple’s System Status to see if it’s a broader issue. For non-Apple apps, check Down Detector.

7. Remove and Reinstall the App

If it’s just your phone, delete the problematic app and re-install it from the App Store. Before you do so, remember that this erases all the app’s local data on your iPhone. For example, if it’s a game app and you did not link your account to other platforms such as Facebook or Google, you will lose all progress.

If you’re sure you want to proceed, go to the Home Screen, long-press the app, and then tap on **Remove App **to uninstall. Choose **Delete App **to confirm. To reinstall the app, go to the App Store and use the **Search **tab to find the app. Tap the Cloud icon to reinstall.
