Quick answer: Restart the phone, update the app and operating system, check storage, force-close and reopen the app, then reinstall it if necessary. Back up important app data before deleting it.
An app may crash because of a bug, outdated software, limited storage, corrupted data, incompatible settings, or a problem with the phone itself. Try the quickest solutions first.
1. Close and reopen the app
Open the app switcher and swipe the affected app away. Wait a few seconds, then open it again. If several apps are crashing, restart the phone instead of repeatedly reopening them.
2. Restart your phone
A restart clears temporary processes and can fix a short-term system problem.
- On iPhone, use the side and volume buttons to power off, then turn it on again.
- On Android, hold the power button and tap Restart.
3. Update the app
Open the App Store or Google Play Store and check for updates. Developers frequently release fixes for crashes and compatibility problems.
Only update through the official app store.
4. Update the phone
Check for an operating-system update in Settings. An outdated system may not work correctly with a newer app version.
Back up important data before installing a major update.
5. Check available storage
Apps may crash when the phone has very little free space. Remove large downloads, unused apps, and unnecessary media. For more help, read How to Free Up Storage on Your iPhone or Android.
6. Clear the app cache on Android.
On many Android phones:
- Open Settings.
- Tap Apps.
- Select the affected app.
- Open Storage.
- Tap Clear cache.
Do not tap Clear data unless you understand that it may sign you out or remove locally stored information.
7. Check permissions.
An app may fail if a required permission is removed. Open the app’s settings and review access to the camera, microphone, storage, location, or contacts.
Grant only the permissions the app genuinely needs.
8. Reinstall the app.
Before uninstalling, confirm that important data is synced or backed up. Delete the app, restart the phone, and install it again from the official store.
9. Check whether the service is down.
If the app works for other people but not you, it may be a local problem. If many users report the same issue, the company’s servers may be unavailable. Wait for the service to recover rather than repeatedly changing your phone settings.
When is the phone the problem?
If many unrelated apps crash, the phone may have a system, storage, battery, overheating, or hardware issue. Back up your data and contact the manufacturer or consider a factory reset as a last resort.
Final verdict
Start with a restart, updates, and storage cleanup. If one app continues to crash, clear its cache on Android or reinstall it after confirming your data is backed up.
