With a few quick steps, you can fix the error in under 5 minutes and get back to what matters.
This guide shows how to quickly solve the problem using simple solutions. Whether you’re facing a slow Android phone or dealing with frequent app crashes, these fixes work across devices. We’ll also explain why this issue happens and how to prevent it in the future. Let’s dive in and solve this once and for all.
1. Restart Your Android Device
Before trying advanced fixes, restart your device. This simple action clears background processes that may cause app lag.

A restart also refreshes the device’s memory. This helps apps run more smoothly. Many users notice a significant performance boost after rebooting.
How to Restart:
- Press and hold the power button.
- Tap “Restart” or “Reboot” on the screen.
- Wait for the device to power back on.
Still having issues after restarting? Let’s move to the next step.
2. Force Stop the Unresponsive App
When an app freezes, forcing it to stop is often effective. This action shuts down all its background activity.
Steps to Force Stop:
- Go to Settings > Apps > See all apps.
- Tap the app causing trouble.
- Select Force Stop, then relaunch it.

Be sure not to confuse force stopping with uninstalling. This step is safe and won’t delete app data.
3. Clear Cache and App Data
Apps store temporary files (cache) which may become corrupted. Clearing them often resolves ‘App Not Responding’ errors.
How to Clear Cache and Storage:
- Open Settings > Apps.
- Choose the app.
- Tap Storage & cache.
- Select Clear cache. If the issue persists, tap Clear storage.
Note: Clearing storage may delete preferences. But it’s necessary if the cache alone doesn’t work.
4. Check for App Updates
Outdated apps may conflict with the latest Android version. Developers release updates to fix bugs and improve performance.
To Update Your Apps:
- Open Google Play Store.
- Tap your profile icon > Manage apps & device.
- Under Updates available, tap Update all or choose the specific app.

Also, update your Android OS from Settings > System > System Update.
5. Free Up Device Storage
Insufficient storage space can slow down your phone and make apps unresponsive. Freeing up space improves app function.
Tips to Free Up Space:
- Delete unused apps, old downloads, or duplicate files.
- Use tools like Files by Google to remove junk.
Also consider using cloud storage like:
6. Uninstall and Reinstall the App
If a specific app keeps crashing, reinstalling it often helps. This removes corrupted files and installs the latest version.
Steps to Reinstall:
- Go to Settings > Apps > Select the app.
- Tap Uninstall.
- Reinstall it from the Play Store.
Make sure to back up any data if needed.
7. Factory Reset as a Last Resort
If all else fails, a factory reset can restore your device to its original state. However, this deletes all data, so back up first.
To Factory Reset:
- Go to Settings > System > Reset options > Erase all data (factory reset).
This method should be your last resort. Use it only after all other steps fail.
Conclusion
‘App Not Responding’ errors can be annoying but are almost always fixable. A quick restart, cache clear, or update can often resolve the problem fast. For persistent issues, a reinstall or reset may be necessary.
By following these quick steps, you can fix most app issues on Android in under five minutes. Keep your phone clean, updated, and well-managed, and you’ll enjoy a smoother experience.
