Difficulty: BeginnerTypical time: 10-30 minutes

The feature or device does not behave as expected.

You may see an error message, warning, delay, or missing response related to this problem.

Before you begin

Important: Save open work before restarting the computer or device. If a step changes accounts, storage, security, or network settings, make a note of the original setting so you can restore it if needed.

Connect the device to reliable power if battery level is low.
Save open documents and close any application that contains unsaved work.
Write down the exact error message or take a screenshot before changing settings.

Step-by-step troubleshooting

Force close and reopen the app

Open the app switcher and dismiss only the affected application, then reopen it.

What you should see: A temporary app process failure should clear.

Restart the device

Power the device off and on, then test the app before opening many other apps.

What you should see: The app should start in a clean system session.

Update the app

Open Apple App Store or Google Play Store and install the latest available version from the legitimate publisher.

What you should see: The app should be current.

Update the operating system

Install a supported system update if the app requirements indicate a newer version or if general stability fixes are available.

What you should see: The app and OS should be mutually compatible.

Check free storage

Make sure the device is not critically low on storage, which can prevent apps from creating temporary data.

What you should see: The device should have working free space.

Reinstall only after confirming app data is safe

Before deleting the app, verify whether its information is synced to an account or backed up. Then reinstall from the official store.

What you should see: A fresh app installation should launch without corrupted local files.

Confirm the problem is resolved

Repeat the action that originally failed and confirm it now completes normally.
Restart the affected application or device once more and verify the fix remains in place.
Confirm that no new warning or error message appears during normal use.

If the problem continues

If none of the steps resolve the problem, stop making additional changes and contact technical support. Provide the exact error text, screenshots if available, the device model, operating-system version, and a list of the steps already completed.

Helpful information to record: the exact error message, when the problem started, what changed immediately before it started, the device model, operating-system version, and which steps above were already attempted.
