To use the CallHippo Android app without interruption, make sure the following requirements are met before troubleshooting any issue:

  1. Do not use a VPN – VPNs can interfere with real-time calling features.

  2. Disable battery optimization for CallHippo – This allows the app to run in the background and stay connected.

  3. Keep the CallHippo app updated – Use the latest version from the Play Store.

  4. Ensure your Android OS is up to date – Outdated systems may cause compatibility issues.

If you're still facing issues, follow the detailed steps below based on the problem you're experiencing.

1. Login Issues

If you're unable to log in:

  • Open the CallHippo app

  • Tap on Forgot Password and follow the steps to reset it

  • Check your email for the reset link and create a new password

  • Reopen the app and log in using your updated credentials

  • If the app still doesn't load, go to Settings > Apps > CallHippo > Storage and tap Clear Cache

Make sure you have a stable internet connection (Wi-Fi or mobile data).

2. Outgoing Call Issues

If you're unable to make outbound calls:

  • Go to Settings > Apps > CallHippo > Permissions
    Ensure Microphone permission is turned on

  • Open the app and dial the number with the correct country code (e.g., +1 for USA)

  • If the call does not connect or disconnects immediately, go to Settings > Apps > CallHippo > Storage and tap Clear Cache

  • Switch networks: If you're on Wi-Fi, try switching to mobile data, or vice versa

  • Restart your phone and try again

Make sure your internet connection is stable and that you're not connected to a VPN.

3. Incoming Call Issues

If you’re not receiving incoming calls:

  • Go to Settings > Apps > CallHippo > Notifications and make sure All notifications are enabled

  • Go to Settings > Battery > Battery Optimization > All Apps > CallHippo, and select Don’t Optimize

  • Check if Do Not Disturb is turned off

  • If your battery is low, note that Low Battery Mode may re-enable battery optimization – disable it manually

  • Allow CallHippo to run in the background:

    • Go to Settings > Apps > CallHippo > Battery > Allow background activity

If you're using any third-party optimizer apps, disable them or whitelist CallHippo.

4. App Crashing or Freezing

If the app crashes when you open it or during use:

  • Go to Settings > Apps > CallHippo > Storage

  • Tap Clear Cache and then Clear Data

  • Open the Play Store and check if an update is available for CallHippo

  • If yes, update the app and restart your phone

  • If the issue continues, uninstall and reinstall the app from the Play Store

Also, ensure your phone has enough free storage space and that your Android version is supported.

5. Auto-Logout or Session Timeout

If you're getting logged out frequently:

  • Confirm that you are not logged in on another device. CallHippo accounts should be used on only one device at a time. Logging in elsewhere will force a logout

  • Go to Settings > Battery > Battery Optimization > All Apps > CallHippo and select Don’t Optimize

  • Go to Settings > Apps > CallHippo > Data Usage and make sure Background data is enabled

  • Keep the app updated to avoid session handling issues

6. Final Troubleshooting Checklist

If issues still persist, check the following:

  • Restart your phone

  • Make sure all permissions are enabled (microphone, notifications, background data)

  • Check that the app is not restricted under parental control or device management tools

  • Avoid force-stopping the app from the app switcher or device settings

  • Disable VPNs, third-party firewalls, or privacy tools that may interfere

  • Try switching from Wi-Fi to mobile data, or vice versa, if call or login issues continue

  • Reinstall the CallHippo Android application from the Play Store
