Seeing the “App Not Responding” message on Android is one of the most frustrating experiences. You open an app, it freezes, and suddenly Android asks whether you want to wait or close it. Sometimes it happens once, sometimes it keeps happening every time you open the same app.
The good news is that this error is usually fixable, and in most cases, it has nothing to do with your phone being broken. I’ve seen this issue occur on brand-new phones, older devices, and everything in between.
In this guide, you’ll learn why the “App Not Responding” error happens and exactly how to fix it, using safe methods that actually work in 2025.
What Does “App Not Responding” Mean?
When Android shows this message, it means the app has stopped responding to the system. This usually happens when:
- The app is overloaded or poorly optimized
- Your phone is low on memory or storage
- The app cache is corrupted
- The app conflicts with the current Android version
- Background processes slow everything down
Android waits a few seconds for the app to respond. If it doesn’t, you see the error.
Restart Your Phone First (Don’t Skip This)
Before trying anything advanced, restart your phone.
This clears temporary memory, stops stuck background processes, and often fixes the issue immediately, especially if the error just started appearing.
If the error disappears after restarting, it was likely caused by a temporary system overload.
Check If the Problem Happens With One App or Many
This step matters.
- If only one app shows the error, the issue is almost always the app itself.
- If multiple apps show the error, the problem is likely system-related.
Knowing this helps you avoid unnecessary steps.
Clear Cache for the Problem App
Corrupted cache is one of the most common reasons apps stop responding.
Go to Settings → Apps, select the problematic app, open Storage, and tap Clear Cache.
Do not tap “Clear Data” unless the app keeps crashing after cache clearing. Clearing data may log you out or reset app settings.
This fix alone solves the problem for many users.
Force Stop the App and Reopen It
If the app is frozen in the background, forcing it to stop can reset its behavior.
Go to Settings → Apps, select the app, and tap Force Stop. Then reopen it normally.
This is especially effective for apps that freeze after running for a long time.
Update the App From the Play Store
Outdated apps often conflict with newer Android versions.
Open the Play Store, search for the app, and check for updates. Developers frequently release bug fixes specifically to address freezing and crashing issues.
If the app hasn’t been updated in a very long time, it may no longer be compatible with your Android version.
Free Up Storage Space on Your Phone
Low storage doesn’t just affect speed—it can cause apps to freeze completely.
If your phone has very little free space, apps may fail to load data correctly and stop responding.
Go to Settings → Storage and try to keep at least 15–20% free space. Remove unused apps, old files, and large downloads if needed.
Check for Android System Updates
System bugs can also cause apps to stop responding.
Go to Settings → Software Update and install any available updates. Even small updates can fix memory management issues that affect app stability.
If the error started after a recent update, give the system some time and clear cache for affected apps.
Disable Battery Optimization for Important Apps
Android aggressively manages battery usage, which sometimes causes apps to freeze when running in the background.
If the error happens with messaging, navigation, or productivity apps, battery optimization may be the reason.
Go to Settings → Battery → App battery usage, select the app, and allow unrestricted or background usage.
This helps apps run smoothly without being interrupted by the system.
Uninstall and Reinstall the App
If clearing cache and updating doesn’t help, reinstalling the app is the next step.
Uninstall the app, restart your phone, and install it again from the Play Store.
This removes corrupted files and gives the app a fresh start.
Check for Conflicting Apps
Some apps don’t work well together, especially system cleaners, launchers, or overlay apps.
If the error started after installing a new app, uninstall it and test again. Apps that display overlays (like screen recorders or floating widgets) are common causes.
Scan for Malware or Bad Apps
In rare cases, malware or ad-heavy apps can cause system-wide instability.
If you notice:
- Random ads
- Phone heating up while idle
- Errors across many apps
Use Google Play Protect and uninstall suspicious apps. Avoid third-party app stores and apps that promise “instant fixes.”
Try Safe Mode to Identify the Problem
Safe Mode disables all third-party apps temporarily.
If the error disappears in Safe Mode, one of your installed apps is causing the issue.
Restart your phone normally and uninstall recently installed apps one by one until the problem is gone.
Reset App Preferences (Advanced but Safe)
Resetting app preferences restores default settings without deleting data.
This can fix permission or background behavior issues that cause apps to freeze.
You’ll find this option under Settings → Apps → Reset app preferences (path may vary by device).
Factory Reset (Only If Nothing Else Works)
If the error keeps happening across many apps and nothing helps, a factory reset may be necessary.
Before resetting:
- Back up all important data
- Sync your Google account
- Save photos and files
This should only be done as a last resort.
Common Mistakes to Avoid
Many users make things worse by:
- Installing “RAM booster” or “speed” apps
- Clearing app data unnecessarily
- Force stopping apps constantly
Android already manages resources efficiently. Manual interference often creates more problems.
How to Prevent This Error in the Future
To reduce the chances of seeing this error again:
- Keep apps updated
- Maintain free storage space
- Avoid low-quality apps
- Restart your phone occasionally
Simple habits prevent most app issues.
Final Thoughts
The “App Not Responding” error on Android is annoying, but it’s rarely permanent. In most cases, it’s caused by cache issues, outdated apps, or system overload—not hardware damage.
By following the steps in this guide, you can identify the cause and fix the problem without losing data or installing risky apps.
