Why Do Apps Keep Crashing? Android and iPhone Fixes

Fix one app first with low-risk steps; investigate the phone only when several unrelated apps fail.

When an app keeps closing, freezing or refusing to open, the cause may be a temporary process error, a bad app update, damaged local data, low storage, an account or network problem, or incompatibility with the phone's software. The safest fix depends on whether one app fails or the entire phone is unstable.

Fastest safe sequence: Reopen the affected app, restart the phone, update the app, install available system updates, check storage and test the network. On Android, clear only the app's cache before considering its stored data. Reinstall only after confirming that important app data is synced or backed up.
Protect your data before destructive steps. Clearing Android app storage or deleting an app can remove downloads, drafts, game progress, authenticator records or other information stored only on the phone. Make sure the app is synced, you know the login and recovery details, and any irreplaceable data is exported first.

What Counts as an App Crash?

These symptoms look similar but are not identical:

Symptom What it means Best first response
App crash The app closes unexpectedly and returns to the Home Screen or displays a stopped message. Reopen once, then update the app and restart the phone.
Freeze or “not responding” The screen stops reacting while the app remains visible. Wait briefly for an important task, then force close only that app if it remains stuck.
Failure to open The app shows its logo, immediately closes, or never reaches the first screen. Check for an update, service outage, storage problem or damaged local data.
Background restart The app reloads when you return after using another app. This can be normal memory management and is not automatically a crash.
Phone restart The whole device shuts down or reboots, not just the app. Investigate system software, heat, storage, recently installed apps and possible hardware problems.

Android and iOS manage background processes themselves. A background app may be suspended or removed from memory so the foreground app can use resources. Android's documentation explicitly allows the system to kill a cached background process when memory is needed.1 That is different from the app crashing while you are actively using it.

Do not swipe away every app as routine maintenance. Google says users do not usually need to close apps, and Apple says there is typically no reason to quit an app unless it is unresponsive.23

Does One App Crash or Do Many Apps Crash?

Only one app fails

The most likely causes are an app bug, incompatible version, corrupted cache or data, broken account session, missing permission, server outage or a problem with one feature. Focus on that app before changing phone-wide settings.

Several unrelated apps fail

Check free storage, pending system updates, overheating, a recently installed Android app, system instability or hardware. If the phone itself restarts, treat it as a device problem rather than reinstalling every app.

Note the exact trigger

Write down what happens immediately before the failure. Does the app crash at launch, after login, when opening the camera, when uploading a file, during a call or only on mobile data? A repeatable trigger helps separate permission, file, network and account problems.

Also record the phone model, operating-system version, app version, date and error wording. If many users report the same issue after the same update, the developer may need to release a fix; repeatedly resetting your phone will not repair a server or app-code problem.

Try These Safe Fixes in Order

  1. Wait a moment if work may still be saving. Force closing can discard an unsaved message, document, recording or upload.
  2. Close and reopen only the affected app. Google and Apple both include this in their official troubleshooting sequences.45
  3. Restart the phone. This clears a temporary process or service problem without erasing personal data.
  4. Update the app from its official store. A newer version may fix a known crash or restore compatibility with a recent system update.
  5. Install available system and Google Play system updates. On Android, menu names vary; on iPhone, use Settings > General > Software Update.
  6. Check device storage. Free space if the phone is close to full, then restart and test again.
  7. Test another network. Disable a VPN temporarily, switch between Wi-Fi and mobile data, and check whether the service itself is down.
  8. Check permissions and account access. A camera, microphone, storage or location feature may fail after a permission was denied.

How much free storage is enough?

There is no single crash threshold for every phone or app. Google warns that Android phones can start having issues when less than 10% of storage is free.6 Large games, video editors and system updates may need much more temporary working space.

Delete only items you recognize, and empty a trash or recently deleted folder only after checking it. Moving photos to cloud storage does not always free device storage until the local copies are optimized or removed.

Storage nearly full? Follow our guide to free Google storage without immediately buying more space.

How to Fix an App That Keeps Crashing on Android

Android menu names differ across Google Pixel, Samsung Galaxy and other brands. Search Settings for the app name if the path below is not exact on your phone.

1. Force stop the affected app

Open Settings > Apps > See all apps, select the affected app and tap Force stop. Reopen it and repeat the action that caused the crash. Do not force stop system components randomly.

2. Clear cache—not storage—first

Open Settings > Apps > [app name] > Storage & cache > Clear cache. Cache contains temporary files and will rebuild. Google describes cache clearing as a temporary way to free space because cached data accumulates again.4

Android app settings used to clear temporary cache while troubleshooting crashes
Clear cache before Clear storage. The second option can erase the app's local information.
Clear storage / Clear data is destructive. Google states that clearing storage permanently deletes all app data.2 Use it only after verifying sync, backups, login credentials, two-factor recovery and any locally stored drafts or downloads.

3. Check Play Store and system updates

In Google Play, tap the profile picture, choose Manage apps & device, then update the affected app. Also check Settings > System > Software updates for the Android security update and Google Play system update. Google documents both update locations, though manufacturers may rename them.7

4. Test Android Safe Mode if many apps fail

Safe Mode temporarily disables downloaded apps. If the phone stops crashing in Safe Mode, a downloaded app is likely responsible. Google recommends removing recently downloaded apps one at a time and restarting normally after each removal.8

The method for entering Safe Mode varies by brand, and some Home Screen widgets may be removed. Check the phone manufacturer's instructions and take a screenshot of the Home Screen first. Safe Mode is not necessary for a single app with an obvious post-update bug.

5. Scan unfamiliar or sideloaded apps

If crashes began after installing an app outside Google Play, remove it and run Google Play Protect. Play Protect checks apps at installation and periodically scans the device for potentially harmful behavior.9 Do not install a random “RAM cleaner,” “crash fixer” or unknown APK as a solution.

6. Reinstall only after protecting data

Confirm that the app's information is tied to an online account or exported, uninstall it, restart the phone and reinstall it from Google Play. If the crash returns immediately with clean local data, the problem may be the current app version, device compatibility, account or server.

How to Fix an App That Keeps Crashing on iPhone

1. Quit and reopen the affected app

Open the App Switcher, find the unresponsive app and swipe up on its preview. Then reopen it. Apple recommends closing an app when it is unresponsive—not continually quitting every background app.3

2. Restart iPhone and update the app

Restart the iPhone, open the App Store, tap the account button or profile picture, choose App Updates and install the available update. Apple's current support instructions place reopening, restarting, app updates and iOS updates before deleting the app.5

3. Check iPhone Storage

Open Settings > General > iPhone Storage. Apple shows recommendations and storage used by each app there.10 Remove large downloaded videos or files only after verifying that another copy exists.

4. Understand Offload App versus Delete App

Offload App

Removes the app itself to free space but keeps its documents and data. Reinstalling may repair a damaged app package while preserving local information. It may not fix corruption inside retained documents or data.

Delete App

Removes the app and related local data. It can provide a cleaner reinstall, but unsynced documents, drafts or progress may be lost.

iPhone does not provide one universal Clear cache button for every third-party app. Some apps include their own download or cache controls. If they do not, offloading or deletion are the system-level choices.

5. Back up before deletion or reset

Apple explains that iCloud Backup stores information and settings that do not already sync to iCloud, but an app developer controls how its data is stored and restored.11 Confirm the app's own sync status; a device backup does not guarantee that every third-party draft or downloaded file will return exactly as expected.

After confirming the data, delete and redownload the app from the App Store. If it still fails, contact the developer through the App Store listing and include the iPhone model, iOS version, app version and repeatable steps.

Fixes for Specific Crash Patterns

The app crashes only after login

Check the service status, automatic date and time, account restrictions and whether the account works in a browser or another device. Do not log out if you cannot access the password, recovery email, phone number or two-factor authentication method.

The app crashes when using the camera, microphone or photos

Review the app permissions. On Android, open the app's App info page and choose Permissions. On iPhone, use Settings > Privacy & Security or the app's page in Settings. Grant only the permission necessary for the feature, then test again.

The app crashes on Wi-Fi but not mobile data

Restart the router, disable a VPN or content filter temporarily and test another Wi-Fi network. If every device on the same connection has trouble, the phone app may be fine. Reset network settings only after simpler testing because it can remove saved networks and other connection settings.

The crash began after an app update

Check the developer's release notes and recent reports. On iPhone, ordinary users cannot install an older App Store version. On Android, downloading an old APK from an unknown website creates a security risk and may expose the account or device. Report the bug and wait for a corrected release rather than sideloading untrusted software.

The crash began after a system update

Install any follow-up system update, update all relevant apps and restart. A developer may need to adapt an app to a changed operating-system behavior. If only one app fails, contact that developer; if many apps and system features fail, contact the phone manufacturer or Apple support.

The app closes during games or video editing

Check heat, storage and whether the app is attempting a workload beyond the phone's available memory. Remove the case temporarily only if the manufacturer permits it, move to a cooler environment and stop charging while testing. Never use ice or water to cool a phone.

When App Crashes May Signal a Bigger Problem

Seek manufacturer support or qualified repair help when:

The entire phone restarts. This is more serious than one app returning to the Home Screen.
Many unrelated apps fail. The problem continues after updates, storage cleanup and restart.
Android still crashes in Safe Mode. Downloaded third-party apps are less likely to be the cause.
The phone overheats at idle. Disconnect power and stop demanding tasks.
The case or screen is lifting. A swollen battery requires immediate safety action.
Storage errors or data loss appear. Back up accessible information before more troubleshooting.
Physical swelling is a safety issue If the case or display is separating, follow our swollen phone battery safety instructions.

Should you factory-reset the phone?

A factory reset is a final diagnostic step—not a normal app fix. Back up the device, confirm account recovery, record authenticator migration steps and verify that important app data is synced. If only one app is broken for many users, a factory reset is unlikely to help.

If the phone continues to restart or crash after a clean setup before third-party apps are restored, contact the manufacturer. Repeated resets can waste time and increase the risk of losing data without repairing faulty hardware.

Frequently Asked Questions

Why does one app keep crashing while other apps work?

The cause is usually specific to that app: a bad update, corrupted cache or local data, account problem, server outage, missing permission or incompatibility with the phone or operating system. Focus on the affected app before changing phone-wide settings.

Does clearing cache delete logins or personal data?

Android's Clear cache option removes temporary files and normally does not erase the app's main stored data. Clear storage or Clear data is different and can permanently erase local app information, settings and sessions. Read the confirmation screen carefully.

How do I clear an app cache on iPhone?

iPhone has no universal per-app cache button. Some apps provide their own cache or download controls. Otherwise, offloading keeps documents and data while removing the app, and deleting removes the app plus related local data.

Does low storage really make apps crash?

It can. Apps and system updates need working space for temporary files and databases. Google warns that Android phones may start having issues below 10% free storage, although the exact amount needed varies by phone and workload.

Should I close all background apps?

No. Both Android and iPhone manage background apps automatically. Close or force stop the affected app when it is frozen or unresponsive; continually clearing every recent app is not required and does not fix a developer-side bug.

Will reinstalling an app fix every crash?

No. It can repair a damaged installation or local data, but it cannot fix a service outage, unsupported device, account restriction or bug in the current release. Protect unsynced data before uninstalling or deleting.

Why do apps crash after a phone update?

An app may need an update for the new operating-system behavior, or the system update may need a follow-up patch. Update the app, restart, install later system patches and contact the app developer if only that app fails.

When should I contact the app developer?

Contact the developer after the app is updated and the low-risk steps fail, especially when one repeatable action causes the crash. Include the device model, operating-system version, app version, exact steps, error wording and whether the issue occurs on another network or account.

Bottom Line

Start small: reopen the affected app, restart, update, check storage and test the connection. On Android, clear temporary cache before considering destructive storage clearing. On iPhone, understand that offloading preserves documents and data while deleting may remove them.

Safe Mode, reinstalling and factory reset belong later in the process. When one app alone fails after a known update, the developer may be the only party that can correct the underlying bug. When the entire phone restarts, overheats or shows physical battery swelling, stop treating it as an ordinary app problem.
