Has your FM WhatsApp stopped working all of a sudden? You’re not alone. Numerous users of the app in 2025 have reported issues, including messages not being sent, the app failing to open, and chats freezing without warning. In this guide, we will illustrate the most common causes of FM WhatsApp not working and how to resolve each one.
Why Is FM WhatsApp Not Working in 2025?
Before leaping to solutions, it is helpful to know what is possibly going wrong. FM WhatsApp is not found on the Play Store and doesn’t follow the usual update rules. That means it is more likely to encounter bugs and other issues.
These are some of the most common reasons FM WhatsApp will not work:
- Your app version is out of date.
- Your phone has little memory or storage.
- The FM WhatsApp server is off.
- You have installed an older or unsupported APK.
- Your phone security settings are preventing the app.
- Once you identify the cause, it is simpler to solve the issue.
Upgrade to the Current FM WhatsApp Version
The most frequent cause of FM WhatsApp freezing or crashing is that it is outdated.
What to Do:
- Go to the official FM WhatsApp website.
- Download the new FM WhatsApp 2025 APK.
- Install it on top of the old one.
- Launch the app and check if it’s working.
- Always download from a reliable source to prevent fake or unsafe APKs.
Clear Cache and App Data
Apps collect temporary files over time that can slow them down. Clearing the cache usually resolves freezing or crashing.
Steps:
- Navigate to Settings > Apps > FM WhatsApp.
- Tap on Storage > Clear Cache.
- If the issue persists, attempt Clear Data (this could log you out).
- Restart your phone and launch the app.
Note: Clearing cache won’t delete your chats. Clearing data could, so backup first.
Verify Your Internet Connection
Slow or intermittent internet is a top cause of messages not sending.
Try This:
- Alternate Wi-Fi and mobile data.
- Turn ON and then OFF Airplane Mode.
- Test your connection in a browser.
- If your other apps are functioning but FM WhatsApp is not, continue.
Clear Space on Your Phone
A full phone can slow down all apps, including FM WhatsApp.
What to do:
- Remove unused apps and files.
- Transfer photos and videos to the cloud.
- Remove junk files using a cleaner app.

Reinstall FM WhatsApp
If all else fails, reinstalling the app can solve hidden bugs.
Steps:
- Backup your chats (FM WhatsApp > Settings > Chat Backup).
- Uninstall the app.
- Download and install the latest FM WhatsApp APK.
- Restore your chat backup.
- Use official sources only to stay safe from malicious versions.
Grant All App Permissions
FM WhatsApp requires permission to read your contacts, storage, and camera.
How to Grant:

- Restart the app and verify if it works.
Check for Ban Issues
Users of FM WhatsApp occasionally get banned by official WhatsApp systems.
Signs:
- You can’t log in.
