20 Ways to Fix Phone Apps That Keep Crashing
1. Restart Your Phone
Start with a simple restart.
A temporary system glitch or stuck background process can cause apps to crash repeatedly.
Restart the phone and open the affected app again.
If the app works normally afterward, the problem may have been temporary.
2. Check if Only One App Is Crashing
Determine whether the problem affects one app or several.
Open a few other apps and test them.
If only one app crashes, the problem is more likely related to that specific app.
If many apps are crashing, investigate storage, operating system, memory, or broader system problems.
3. Force Close the Problem App
An app may remain stuck in the background.
On Android, open the app information screen and select Force Stop if available.
Then launch the app again.
On iPhone, close the app from the app switcher and reopen it.
This can clear a temporary app process without deleting your data.
4. Update the App
An outdated app may contain bugs or compatibility problems.
Open the official app store and check for an available update.
Install the latest official version.
App developers frequently release updates to fix crashes, security problems, and compatibility issues.
5. Update Your Phone Software
The app may be compatible with a newer version of Android or iOS.
Check your phone’s system update settings.
Install available official updates and restart the device afterward.
Keeping both the app and operating system updated can prevent compatibility problems.
6. Free Up Storage Space
Low storage can affect app performance.
Check your phone’s available storage.
If storage is almost full, remove unnecessary:
- Videos
- Photos
- Downloads
- Large files
- Unused apps
- Duplicate files
Try to keep some free storage available instead of using the phone until it reaches zero.
7. Clear the App Cache on Android
A corrupted cache can sometimes cause repeated crashes.
On many Android phones, you can find the option under:
Settings → Apps → [App Name] → Storage → Clear Cache
The exact menu can vary by phone manufacturer.
Clearing the cache normally removes temporary files rather than your account or personal data.
Do not select Clear Data unless you understand what information the app may remove.
8. Clear App Data if Necessary
If clearing the cache doesn’t help, resetting the app’s stored data may fix deeper corruption.
On Android, this may appear as:
Clear Data or Clear Storage
Be careful because this can:
- Sign you out
- Remove saved app settings
- Delete locally stored app information
- Reset the app
Make sure important information is backed up or synchronized before using this option.
9. Check Your Internet Connection
Some apps depend heavily on an internet connection.
If the app crashes while loading online content, test your connection.
Try:
- Wi-Fi
- Mobile data
- Another Wi-Fi network
If the app works on one network but crashes on another, the problem may involve network restrictions or connectivity.
10. Temporarily Disable VPN
A VPN can sometimes interfere with certain apps or services.
If you use a VPN, disconnect it temporarily and test the app.
If the app stops crashing after disconnecting the VPN, check the VPN configuration or contact the VPN provider.
Do not leave your device without appropriate security simply to test an app for a long period.
11. Check App Permissions
An app may need access to features such as:
- Camera
- Microphone
- Location
- Photos
- Files
- Contacts
Open the app’s permission settings and make sure required permissions haven’t been accidentally disabled.
Only grant permissions that the app actually needs.
12. Check Battery Saver Restrictions
Aggressive battery-saving settings can restrict app activity.
If the app crashes or stops working after being in the background, check battery optimization settings.
For an important app, you may be able to allow normal background activity.
Menu names vary by phone manufacturer.
Avoid disabling battery-saving features for every app unless necessary.
13. Close Unused Background Apps
Too many demanding apps running at the same time can reduce available memory.
Close unnecessary apps and then reopen the problem app.
This is especially useful on phones with limited RAM or when using resource-intensive applications such as games, video editors, and social media apps.
14. Check the Phone for Overheating
Excessive heat can cause apps to become unstable.
Your phone may become hot when:
- Playing demanding games
- Recording video
- Using navigation
- Charging while heavily using the phone
- Running many apps
- Using the phone in direct sunlight
Let the phone cool naturally before testing the app again.
Do not place a hot phone in a freezer or use extreme cooling methods.
15. Check the Date and Time
Incorrect system date or time can cause problems with online services, authentication, certificates, and app connections.
Enable automatic date and time if your phone provides that option.
Then restart the affected app and test it again.
16. Reinstall the Problem App
If the app installation is corrupted, reinstalling it may fix repeated crashes.
Before uninstalling, make sure important app data is synchronized or backed up.
Then:
- Uninstall the app.
- Restart the phone if necessary.
- Download the app again from the official app store.
- Install it.
- Sign in.
- Test the app.
Avoid downloading APKs or modified app packages from unknown websites.
17. Check Google Play Services on Android
Android apps can depend on Google Play Services and related system components.
If multiple apps suddenly start crashing, check whether Google Play Services and the Google Play Store have available updates.
Restart the phone after installing official updates.
If a specific system component is causing the problem, updating it can restore app compatibility.
18. Check for a Problematic Recent Update
If an app started crashing immediately after an update, the update itself may contain a bug.
Check the app’s official store listing for another available update.
You can also check recent user reports or the developer’s support information to see whether the issue is widespread.
Avoid installing unofficial older versions from untrusted sources.
19. Reset App Preferences or Relevant Settings
If many apps are affected, resetting certain app-related preferences can help.
On some Android phones, Reset App Preferences restores disabled apps, default applications, permission preferences, and other app settings.
This usually does not delete personal files, but the exact behavior can vary.
Read the confirmation screen carefully before proceeding.
On iPhone, you may instead consider resetting relevant settings if normal troubleshooting has failed.
20. Contact the App Developer or Phone Manufacturer
If an app continues crashing after all basic troubleshooting, professional support may be necessary.
Contact the app developer if:
- Only one app is affected.
- The crash happens after a specific action.
- The problem started after an app update.
- Other users are reporting the same issue.
Contact your phone manufacturer if:
- Multiple unrelated apps crash.
- The phone frequently freezes.
- The device restarts unexpectedly.
- System settings also stop responding.
- The phone has suffered physical or liquid damage.
Phone Apps Keep Crashing After an Update
If apps started crashing after a phone or app update, don’t immediately assume the phone is damaged.
Try:
- Restarting the phone.
- Updating all apps.
- Checking for another system update.
- Clearing the affected app’s cache.
- Checking available storage.
- Reinstalling the affected app.
If several apps started crashing at exactly the same time, the issue may be related to a system component rather than each individual app.
One App Keeps Crashing
If only one app crashes while everything else works normally, focus on that app.
Try:
- Force closing it
- Updating it
- Checking permissions
- Clearing its cache
- Checking your internet connection
- Disabling VPN temporarily
- Reinstalling it
If the app still crashes, check the developer’s support page or official app-store information for known problems.
All Apps Keep Crashing
When many unrelated apps crash, look beyond individual apps.
Possible causes include:
- Very low storage
- System software problems
- Memory problems
- Failed system updates
- Corrupted system components
- Severe overheating
- Hardware issues
Restart the phone, free storage, install official updates, and check whether the problem continues.
If the entire phone is unstable, professional support may be required.
Apps Crash When Opening
If an app closes immediately after tapping its icon, try:
- Restarting the phone.
- Force closing the app.
- Updating the app.
- Clearing its cache on Android.
- Checking available storage.
- Checking required permissions.
- Reinstalling the app.
If the app still closes immediately, the installation or app version may be incompatible with your device.
Apps Crash When Using Mobile Data
If an app works on Wi-Fi but crashes or stops working on mobile data, check:
- Mobile data is enabled.
- The app is allowed to use mobile data.
- Data Saver isn’t blocking the app.
- Your mobile data connection is stable.
- A VPN isn’t interfering.
- Your carrier connection is working normally.
Test another online app using mobile data to determine whether the problem is specific to the app or the network.
Is It Safe to Clear an App’s Cache?
Generally, clearing an app’s cache is a low-risk troubleshooting step.
It removes temporary files that the app may recreate later.
However, Clear Data or Clear Storage is different and can remove locally stored information or sign you out.
Always check what your phone says before confirming.
When Should You Factory Reset the Phone?
A factory reset should not be your first solution for app crashes.
Consider it only after:
- Restarting
- Updating apps and the operating system
- Freeing storage
- Reinstalling affected apps
- Troubleshooting system settings
- Backing up important data
A factory reset erases personal information and returns the device to its initial setup state.
If multiple apps continue crashing despite all normal troubleshooting, consult the phone manufacturer before performing a factory reset.
Safety and Data Protection Tips
Keep these precautions in mind while troubleshooting:
- Download apps only from official app stores.
- Avoid modified or pirated applications.
- Don’t download random APK files from unknown websites.
- Back up important data before resetting an app.
- Understand what “Clear Data” will remove.
- Back up your phone before a factory reset.
- Don’t install suspicious apps claiming to repair crashes.
- Keep your operating system updated.
- Don’t continue using a phone that becomes dangerously hot or shows physical battery damage.
If the phone has a swollen battery, smoke, burning smell, or severe overheating, stop using it and seek professional service.
