How to Fix Apps Not Working on iPhone After Update? Many Apple users have complained that after updating to iOS 17/16, many apps no longer work properly. The app not operating after the iOS 17 upgrade can be linked to two major causes: For starters, as we all know, iOS 17 beta is simply a trial version, thus many software developers have yet to create versions compatible with iOS 17 or 16. Nothing can be done in this circumstance but wait for updates. Second, there are unidentified software malfunctions or system crashes, which we will address in this post.
What’s wrong with my iOS 17/iOS 16 apps?
iOS 17 is finally available for testing. Even if you can update your iPhone or other iOS devices to the latest iOS version from Apple, you should not. You must try the iOS 17 version to be among the first to experience its new features such as system-wide dark mode, a freshly designed camera interface, and much more.
Along with bug fixes and new features, Apple releases a beta version so that developers can prepare their services and apps for the final release. As a result, it is possible that some of the apps installed on your iPhone will not function properly.
How to Fix Apps Not Working on iPhone After Update?
Here is the list of 10 Methods to Fix Apps not working on iPhones After an Update:
1. Restart Your iPhone
Restarting your iPhone is another approach to renewing the network connection. You can try technique 1 and method 2 alternately, and in most circumstances, either will work for you. To force restart your devices, follow the procedures below:
- If you have an iPhone X or a later model, including the SE 2, push the volume up and down buttons, then long press the side button until the Apple logo shows.
- If you have an iPhone 7 or 7 Plus, long press the volume down and side buttons at the same time until the Apple logo shows.
- If you’re using an iPhone 6S or earlier model, hold down the home and power buttons at the same time until you see the Apple logo.

2. Turn On and Off Airplane Mode
Apps that do not work on iPhones are most frequently due to an unstable and bad network connection. If this is the case, toggling on and off Aeroplane Mode will allow you to effortlessly renew your network connection. There are two ways to accomplish this.
- Go to Settings > Turn on Aeroplane Mode immediately underneath [Your Name], then turn it off, and your device will connect to the Internet automatically.
- Swipe down from the top of your unlocked screen to access the control centre, namely the status bar. Then you’ll notice an aeroplane sign. Tap it to activate Aeroplane Mode, then wait a minute before turning it off.

Given that this method is not ideal for frequent use, you can go to Method 3 to find a lasting solution.
3. Reset Network Settings to Fix Apps not working on iPhone After Update
Reset Network Settings can permanently resolve various network issues caused by iOS version upgrades, such as bad cellular network or WiFi connection issues, and restore all of your network settings. For example, the WiFi password that the iPhone previously memorised will be deleted. Here’s how to clear your network settings:
- Launch the Settings app and select General.
- Select Reset.
- Select and confirm Reset Network Settings.

4. Remove and Reinstall the App
Sometimes it appears that no amount of troubleshooting will allow an update to be installed. If this occurs, simply uninstall the program and reinstall it from the program Store. If it’s a paid app, don’t worry, you won’t have to pay for it again. The program Store remembers every program you’ve ever installed and lets you reload them with a single swipe.
To delete an app, tap and hold it until it jiggles, then tap the delete (X) symbol to remove it. Then, to stop the jiggling, tap the home button or swipe up from the bottom of the screen. Go to the program Store, search for the program you just uninstalled, and then tap the Redownload icon to reinstall it.

5. Restart the App to Fix Apps not working on iPhone After Update
Close the app completely and reopen it by swiping up from the bottom of the screen and selecting the troublesome app. Then reopen the app.

6. Turn Off Do Not Disturb
Check to see if you’ve activated the Do Not Disturb option. Although it is intended to disable all ringtones and notifications except the alarm clock, it may also impair app performance. Here’s how to disable it:
- Launch the Settings app.
- Scroll down and hit on Do Not Disturb.
- Deactivate the Do Not Disturb setting.

7. Force the App to Close
The next step is to force close an app if it is still not working after the iOS 17 update. Apps may crash or stop running suddenly if they are unable to perform a required operation at the same time. Meanwhile, forcing an app to close shuts down the program and its processes, which are then restarted when you reopen it. That is a method for sometimes resolving app not working issues.
Here’s how it’s done:
- To use the app switcher, swipe up from the bottom of the screen.
- Swipe up on the afflicted app to open it.

8. Contact the App Developer
If nothing else works, you should contact the app’s developer for further assistance, especially if this is a third-party app. Because app developers are accountable for the upkeep of their programs. Here’s how to get in touch:
- Navigate to the App Store on your iOS 17 device.
- Enter the app’s name into the search field to find it.
- Find your app.
- Select Developer Website. As a result, you can contact the developer.

10. Downgrade to iOS 15
Upgrading to iOS 16 beta will provide you with many new experiences; but, if a malfunctioned program, such as Safari, Camera, Twitter, or Instagram, is substantially interfering with your everyday life, it is recommended that you revert to the stable iOS version.
