How to Fix “App Not Responding” Errors on Android in 2025

Nothing is more frustrating than launching an app on your Android device, only to see it freeze or crash with the dreaded “App Not Responding” (ANR) message. In 2025, as apps grow more complex and devices handle increasing workloads, encountering ANR errors is still a common issue.

If you’re struggling with ANR errors, don’t worry. This guide explains what causes them and provides practical solutions to fix “App Not Responding” errors on Android so you can enjoy a smoother app experience.


What Is an “App Not Responding” (ANR) Error?

An ANR error occurs when an app fails to respond to a user’s input within a specific time frame. For example, if you tap a button in an app and it doesn’t respond promptly, Android may assume the app has frozen and display a pop-up stating:
“App isn’t responding. Do you want to close it?”

Common Causes of ANR Errors:

  1. Overloaded Device Resources: Running out of RAM or CPU power.
  2. Software Bugs: Issues in the app’s code or compatibility problems.
  3. Background Processes: Too many apps running in the background.
  4. Corrupt App Data: Damaged cache or configuration files.
  5. Outdated App or OS: Apps may not be optimized for older Android versions or vice versa.

How to Fix “App Not Responding” Errors

Here’s a step-by-step guide to troubleshooting and fixing ANR errors on your Android device.

1. Force Stop the App

When an app freezes, the quickest solution is to force stop it and relaunch it.

Steps:

  1. Go to Settings > Apps & Notifications (or just Apps).
  2. Select the problematic app from the list.
  3. Tap Force Stop.
  4. Relaunch the app to see if the issue is resolved.

2. Restart Your Device

Sometimes, a simple restart can fix temporary glitches causing ANR errors.

Steps:

  1. Press and hold the Power Button.
  2. Select Restart (or Power Off, then turn it back on).
  3. Open the app again to check if the problem persists.

3. Clear App Cache and Data

Corrupt cache files or app data can lead to performance issues.

Steps:

  1. Go to Settings > Apps.
  2. Find the app that’s causing the issue.
  3. Tap Storage & Cache (or Storage).
  4. Select Clear Cache. If the issue persists, tap Clear Data (note: this will reset the app).

4. Update the App

Outdated apps may have bugs that cause them to freeze or crash. Developers often release updates to fix these issues.

Steps:

  1. Open the Google Play Store.
  2. Search for the app and check if an update is available.
  3. Tap Update if prompted.

5. Check for Android System Updates

Sometimes, the problem isn’t the app but your operating system. Updating your Android OS can fix compatibility issues.

Steps:

  1. Go to Settings > System > Software Update.
  2. Tap Check for Updates.
  3. If an update is available, download and install it.

6. Free Up Device Storage

Apps require sufficient storage space to function properly. Running low on storage can cause ANR errors.

Steps:

  1. Go to Settings > Storage.
  2. Identify and delete unused apps, large files, or unnecessary media.
  3. Use a cleaner app like Files by Google to remove junk files.

7. Reduce Background Processes

If too many apps are running in the background, it can overload your device’s resources.

Steps:

  1. Open Settings > Apps.
  2. Force stop unnecessary apps running in the background.
  3. Use Battery Saver Mode to limit background processes.

8. Reinstall the App

If clearing cache and data doesn’t work, reinstalling the app can fix deeper issues.

Steps:

  1. Go to Settings > Apps and select the app.
  2. Tap Uninstall.
  3. Reinstall the app from the Google Play Store.

9. Check for Malware or Viruses

Malware can cause apps to misbehave. Running a virus scan can rule out security threats.

Steps:

  1. Download a trusted antivirus app like Malwarebytes or Avast Mobile Security.
  2. Run a full device scan.
  3. Remove any detected threats and restart your device.

10. Install a Lighter Version of the App

If your device is older or has limited resources, consider using lite versions of apps designed for low-performance devices.

Examples:

11. Reset Network Settings

For apps that rely on the internet, poor connectivity can trigger ANR errors. Resetting network settings can help fix these issues.

Steps:

  1. Go to Settings > System > Reset Options.
  2. Select Reset Wi-Fi, Mobile, & Bluetooth.
  3. Reconnect to your network and test the app.

12. Factory Reset Your Device (Last Resort)

If all else fails, a factory reset can fix persistent ANR errors caused by deep system issues. Note: This will erase all data, so back up your files first.

Steps:

  1. Go to Settings > System > Reset Options.
  2. Select Erase All Data (Factory Reset).
  3. Follow the on-screen instructions.

How to Prevent “App Not Responding” Errors

  1. Keep Apps and OS Updated: Regularly update both apps and your Android system to avoid compatibility issues.
  2. Monitor Storage: Keep at least 20% of your device’s storage free for optimal performance.
  3. Avoid Overloading Your Device: Don’t run too many apps simultaneously, especially on older devices.
  4. Install Apps from Trusted Sources: Avoid APKs from unverified sources to reduce the risk of malware.

FAQs About “App Not Responding” Errors

1. Why does my app keep freezing?

Apps freeze due to reasons like low RAM, software bugs, corrupt data, or outdated versions.

2. Can I fix ANR errors without uninstalling the app?

Yes. Clearing cache, updating the app, or restarting your device often fixes the issue without uninstalling the app.

3. Is factory resetting my device safe?

Yes, but it should only be used as a last resort. Always back up your data before performing a factory reset.

4. Do ANR errors mean my phone is outdated?

Not necessarily. ANR errors can happen even on newer devices due to app-specific bugs or resource-intensive tasks.

5. Are ANR errors preventable?

Yes. Regular maintenance, such as updating apps, freeing up storage, and clearing cache, can reduce the likelihood of ANR errors.
