If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.


To begin troubleshooting your device, below are the steps that you must do:

Use wifi when downloading or updating apps

Interruptions during an update, whether in the download phase or installation phase, must be kept to a minimum to avoid problems. In worst cases, interrupting a system that’s trying to install an update can lead to boot problems, including failure to load the operating system. To ensure that app updates are not interrupted, use a reliable wifi network. Try to avoid using cellular network during updates. Not only will it minimize the chance of having your updates interrupted but it can also help you lessen your bills.

To check if your wifi connection is fast enough, try to open a video and stream it. If it loads quickly, you’re good to go.

Pause and restart app download

Sometimes, temporarily pausing the update then resuming it after a few moments can fix some update bugs. If you haven’t tried it yet, here’s how you can can do this step.

  1. From the Home screen, press and hold the app you’re trying to update.
  2. You will see the options to Resume Download, Pause Download, or Cancel Download. If the app download is paused for whatever reason, tap Resume Download.
  3. If the update is stuck and won’t progress after resuming the download, tap Pause Download.
  4. Then, press and hold the app again and tap Resume Download.

Restart your iPhone 8

A lot of minor bugs can be fixed by doing a simple restart. If you find yourself mired in an update issue, it’s good if you can kick off your troubleshooting with a restart. It refreshes the system and eliminates bugs that may have developed after leaving your phone on for a long time.

We suggest that you simulate a virtual “battery pull” instead of the regular restart. Here’s how:

  1. Press and quickly release the Volume up button then press and quickly release the Volume down button.
  2. To complete, press and hold the Side (Power) button until the Apple logo appears on the screen.

Verify the Apple ID

Apps are associated with an Apple ID. if you’re using multiple Apple IDs, there’s a chance that you’re currently signed in to the one that’s not associated with the apps that won’t update.

To check the Apple ID you used for an app, follow these steps:

  1. Launch the App Store app.
  2. Tap Updates.
  3. Tap Purchased.
  4. Check to see if the app is listed here. If not, it was likely downloaded with another Apple ID.

If you are using iTunes, you can verify the Apple by following these steps:

  1. Go to your list of apps.
  2. Right-click the app you’re interested in.
  3. Click Get Info.
  4. Click the File tab.
  5. Look at Purchased by for the Apple ID.

Turn Restrictions off

Average users don’t usually find Restrictions feature useful at all but for those tasked with managing company devices, it might be. Restrictions feature can disable certain features of your iPhone including its ability to install apps. To ensure that you did not enable it by accident, here’s how to check it:

  1. Tap Settings.
  2. Tap General.
  3. Tap Restrictions.
  4. If prompted, enter your passcode
  5. Check the Installing Apps menu. If the slider is set to off/white then updating apps is blocked. Move the slider to on/green to restore the updating feature.

Ensure your iPhone has enough available storage

One common mistake a lot of iPhone storage make is to allow their device to accumulate a lot of stuff and leave barely enough storage for iOS and app updates. Be sure to make it a point to always leave at least 1GB of storage space free for such eventualities.

To check the available storage space in your phone, follow these steps:

  1. Tap Settings.
  2. Tap General.
  3. Tap About.
  4. Look for the Available line. Whatever figure you see should be the available storage space for your device.

Sign in and out of App Store

Another simple troubleshooting step that sometimes work in this situation is signing out and signing back in to the App Store. To do that, follow these steps:

  1. Tap Settings.
  2. Tap iTunes & App Store.
  3. Tap the Apple ID menu.
  4. In the pop-up menu, tap Sign Out.
  5. Tap the Apple ID menu again and sign in with your Apple ID.

Install latest iOS update

Whether you’re having an issue or not, it’s always highly recommended that you install the latest available iOS update whenever they become available. At times, newer versions of apps require the corresponding iOS version. If you’re still running an older iOS, app update may not proceed.

Ensure system time and data are correct

If you tend to change your iPhone’s date and time from time to time (very useful when playing some particular games), the reason why you can’t install app updates is incorrect time and data. Apple performs a complex set of checking when installing an update and one important consideration is the device’s date and time. If your system time and date are way off, updates may not be downloaded by Apple to your device. To fix the problem, simply set the time and date back to that of your network’s. Here’s how:

  1. Tap Settings.
  2. Tap General.
  3. Tap Date & Time.
  4. Move the Set Automatically slider to on/green.

Delete App Store cache

Every app keeps a temporary set of files called cache to store settings and other information that can help them operate faster. Sometimes, this type of cache gets corrupted and can lead to bugs. To see if App Store cache is the culprit, consider emptying it. Don’t worry, the app will gradually the cache over time so you can do it safely. Doing so won’t affect other files.

  1. Open App Store app.
  2. Tap any of the icons at the bottom of the app 10 times. This will force the app to restart and redirects to the first tab. Once this happens, this means that the app cache was already cleared.

Delete and reinstall app

Another direct way to deal with an app not updating  issue is by removing it from the system and reinstalling it. At times, refreshing the system and app this way does the trick.

There are a few methods to delete an app.

Delete apps via Home screen

  1. Look for the app you want to uninstall on your iPhone’s home screen.
  2. Tap and hold on the app icon until all the apps begin to wiggle.).
  3. When the apps begin to wiggle, you’ll notice an X appears on the top left of the icon. Tap that.
  4. A window pops up asking if you really want to delete the app. If you’ve changed your mind, tap Cancel. If you want to proceed, tap Delete.
  5. If the app is a Game Center-compatible, or stores some of its data in iCloud, you’ll also be asked whether you want to remove your data from Game Center/iCloud or leave it.

Delete apps via iTunes

  1. In your computer, ensure that iTunes is up-to-date.
  2. Also, make sure that you computer runs the latest available update for its operating system. Some update errors can occur if a computer’s operating system is not recent.
  3. Connect your iPhone 8 to your computer.
  4. Launch iTunes and select your device.
  5. Click the Apps tab.
  6. In the left-hand column, you’ll see a list of all the apps installed on your iPhone. Scroll through it and find the one you want to get rid of.
  7. Click the Remove button next to the app. Repeat this process for as many apps as you want to remove.
  8. When you’ve marked all the apps you want to remove, click the Apply button at the bottom right corner.
  9. Your iPhone will sync again using the new settings, removing these apps from your phone (though the app is still stored in your iTunes library).

Delete apps via Settings app

  1. Open Settings app.
  2. Tap General.
  3. Tap Usage.
  4. Tap Manage Storage. This screen shows all the apps on your phone and how much space they take up.
  5. Tap any third-party app in the list (this won’t work with stock iPhone apps since you can’t delete them).
  6. On the app detail page, tap Delete App.
  7. In the menu that pops up from the bottom of the screen, tap Cancel to keep the app or Delete App to complete the uninstall.

Reset all settings

Any of the suggestions above should have already fixed the issue. However, if apps still fail to update, you should consider resetting all settings. Only your iPhone settings will be deleted by this procedure so your data will remain intact. Here’s how to do it:

  1. Open Settings app.
  2. Tap General.
  3. Tap Reset.
  4. Tap Reset All Settings.
  5. You may be asked to enter your passcode. If you are, do so.
  6. In the pop-up window, tap Reset All Settings.

Perform a factory reset

  1. Create a backup of your files via iCloud, iTunes, or both.
  2. Open Settings app.
  3. Tap General.
  4. Tap Reset.
  5. Tap Erase All Content and Settings.
  6. If prompted, enter your passcode.
  7. Tap Erase iPhone.
