Is Com Sec Unifiedwfc Malware?

Since Com Sec Unifiedwfc is an official Samsung service, users can rest assured it is not malware or a scam.

As it is deeply integrated with the phone’s calling functions, it requires high-level permissions. This has led some overzealous anti-virus apps to incorrectly flag it as malware.

If for any reason you wish to stop using Com Sec Unifiedwfc, you can simply disable Wi-Fi calling in the phone settings. This will completely stop the background app and services from functioning.


Common Issues Faced with Com Sec Unifiedwfc

While Com Sec Unifiedwfc delivers improved calling functionality, some users have reported facing issues like:

  • Random crashing – The app unexpectedly stops with no error message.
  • Failure to connect calls – Outgoing calls get stuck trying to connect.
  • Call drops – Ongoing calls abruptly disconnect without reason.

These issues can be frustrating as they prevent users from making calls. Thankfully, there are some troubleshooting steps that can be taken to resolve them.

What Causes These Issues?

Based on user reports, a few key reasons have been identified that likely cause the calling issues:

  • Outdated software – The Android OS or Com Sec app itself may not be updated.
  • Unstable internet – Poor Wi-Fi connection leading to call interruptions.
  • Cache problems – Too much cached data crashes the app.

Let’s analyze these factors a bit deeper:


Outdated Software

  • Com Sec Unifiedwfc relies on the latest software to run smoothly.
  • If the Android OS is outdated, new app features may not work properly.
  • Similarly, if the Com Sec app has pending updates, bugs could be present.
  • Using outdated systems can lead to crashes and call failures.

Unstable Internet

  • Stable internet is vital for Wi-Fi calling to function.
  • Weak Wi-Fi networks or fluctuating cellular data cause call drops.
  • Switching between Wi-Fi and cellular can also disrupt calls.
  • Lack of internet bandwidth will prevent calls from connecting.

Cache Problems

  • Too much cached data can overload the app over time.
  • This leads to crashing and call failures after extended use.
  • Cache clearing reverts the app to stable defaults.
