Check your internet connection

A weak or unstable internet connection can cause apps to freeze or close.

1. Switch between Wi-Fi and mobile data to see if the problem improves.

If you have an Android phone, clearing an app’s cache and data can help.

1. Go to Settings > Apps.
2. Select the app that’s crashing.
3. Tap Storage > Clear cache.
4. If the issue continues, try Clear data (note: this may sign you out of the app).

Offload or reinstall the app (iPhone)

For iPhones, removing and reinstalling an app can clear out corrupted files.

1. Go to Settings > General > iPhone Storage.
2. Select the app and choose Offload App or Delete App.
3. Reinstall the app from the App Store.

Update your phone’s operating system

App crashes can happen if your phone’s software is out of date.

1. Go to Settings > Software Update (iPhone) or Settings > System update (Android).
2. Install any available updates.

Check app permissions

Some apps need permission to access your camera, storage, or location.
