Everyone has their favorite iPhone apps. Some of yours might be for practical purposes, while others may be for entertainment. If your apps keep crashing after iOS 17 update, then you’ll need to figure out a solution so that you can get the best use from your device again. Let’s talk about why your apps are crashing after iOS 17 update, and what you can do to fix the issue.

How to fix apps that keeps crashing after iOS 17 update

Follow the steps below to fix apps that keeps crashing after iOS 17 update:

Rebooting May Keep Your iPhone Apps from Crashing

An internal error with some of your apps might prevent them from working properly. To resolve this problem, the first thing that you can try is to reboot your iPhone.
To reboot your iPhone XR, XS, 11, 12, 13 or 14:

  1. Press and hold either **volume** button and the **side** button until you see the **power off** slider on the display.
  2. Slide the slider from left to right, then wait a few seconds for your device to turn off completely.
  3. To turn your device back on, press and hold the **side** button until the **Apple logo** appears on the display.

To restart your iPhone SE (2nd generation), or higher:

  1. Press and hold the **side** button until you see the **power off** slider on the screen.
  2. Drag the slider from left to right, then wait a few seconds for your device to turn off completely.
  3. To turn your device back on, press and hold the **side** button until the Apple logo appears on the screen.

Once your iPhone has fully restarted, try opening an app and see if it works any better. If it doesn’t, proceed to the next solution.

Try Updating Your Apps if your apps keeps crashing after iOS 17 update

iPhone apps still keep crashing on your iOS 17 device? The next solution you can try is to update any of your apps that have a newer version. You should get automatic notifications whenever an update is available for any of your apps. It will appear as a small blue number in a circle on the lower right-hand side of the app store logo. When you press it, you will see an Updates option at the bottom of the screen. Hit it to see what apps need updating, then hit Update All at the top right-hand side of the screen.
It’s possible, though, that you might not have gotten that notification for some reason, but updates for some of your apps still exist. You can always look into the status of your apps through the App Store without being notified that a newer version is available. Just open the App Store, tap My Account, and then hit Update All at the top of the screen. Then wait as the new versions of the apps download, and try the ones that have been giving you trouble.

Reinstall the Apps if Your iPhone Apps Keep Crashing after iOS 17 update

If updating your apps didn’t resolve the problem, you can next try reinstalling the apps. If it’s just a couple of apps that are not working after iOS 17 update, then you can reinstall only those ones. If all of them aren’t working as they should, then you’ll need to do this with all of them. It’s cumbersome, but it could prove to be the solution.
Locate the icon of each troublesome app on your screen, and press down on it until all of the apps start to wiggle. You should see an “X” next to each of the apps. Hit the X for each of the apps that you would like to uninstall.

To reinstall each app, go to the App Store. Search for the app you just deleted by typing their names into the search field. Once you have found one, click the Cloud icon that appears beside it. The app will soon download again, and then you’re free to use it. Hopefully, the apps will stop crashing on your iOS 17 device.
You should know that some apps are free, while others cost money. However, if you deleted an app that you previously purchased, then you should be able to erase it and download it again without having to pay for it a second time. If the App Store tries to make you pay for the app again, then contact the app developer. By paying for the app once, you should have a license to use it going forward.

Try Updating Your iPhone

The next solution you should try if apps still keep crashing on your iOS 17 device is to update your iPhone. Your software might be out of date, and that can lead to all sorts of problems.
Go to Settings, then tap General.
Tap Software Update where you see that option at the top of the display.
If there is a more recent version of iOS than the one that you are running, you will see the option to Install Now in blue. Tap the button, and the update will begin installing. If your iPhone is running the latest version of operating system, then you will see that message. If that’s the case, you’ll need to look into some other options to fix your app problem.

Do a DFU Restore if Your iPhone Apps Keep Crashing in iOS 17

We have now gotten to the point where, if your iPhone apps are still crashing, you’ll need to do something a little more drastic. A DFU restore of your iPhone might be the way to go. This is a special kind of restore that is intended to wipe clean both the hardware and software of your Apple device. You will end up with a completely clean iPhone.
Since all of your content and settings will be erased if you do this, you should always back up your iPhone before you go this route. You can do so either with iTunes or iCloud, whichever you prefer.

  1. Build a connection between your iPhone and computer using a Lightning to USB cable. If this is your first time connecting your iPhone to this computer, you’ll need to tap the Trust button that appears on the Trust This Computer dialogue that appears. You’ll then have to enter your passcode on your iPhone to confirm the pairing.
  2. Next, perform the following steps in quick succession:
    • Press **Volume up** and let go.
    • Press **Volume down** and let go.
    • Press and keep holding the **Side** button for 10 seconds.
    • While still holding the **side** button, press and hold the **Volume down** button for 5 seconds.
    • Let go off.the **Side** button and keep pressing the **Volume down** button for an additional 10 seconds.

When you successfully enter DFU mode, your iPhone should remain on a black screen. If you see the Apple logo appear, then something went wrong and you’ll need to try again.
You can now restore your phone using iTunes.
This is the “deepest” type of restore that you can do with an Apple device, so it is likely that this will keep your apps from crashing if nothing else will.

What if None of these Solutions Have Worked?

If you’ve tried everything that we’ve mentioned but your iPhone apps keeps crashing after iOS 17 update, then you should contact Apple Support. You can contact them via online live chat, but it’s probably going to make more sense to bring the phone into an Apple Store with a Genius Bar if there is one close to you. The Geniuses can look it over and figure out what’s happening with it.

The issue is probably hardware related. An internal component of your phone might have been damaged that is affecting your ability to run the apps successfully. If your iPhone is still under factory warranty, then it shouldn’t cost you anything to get it fixed. If the warranty has expired, then you’ll need to pay for the repair yourself. Likely you’ll find it worth it, though, since an iPhone that can’t run your favorite apps isn’t going to be very useful to you.
