Com.sec.unifiedwfc explained

Most Android apps follow a specific format for package names. The usual format is com.developer.app. In the case of com.sec.unifiedwfc, the package name denotes a WiFi calling service made by Samsung. the SEC in the package name stands for Samsung Electronics Co. Ltd, and unifiedwfc stands for Unified WiFi Calling. 

The app is specific to Samsung phones and helps facilitate WiFi calling regardless of the carrier used. WiFi calling is used every time you’re connected to a secure WiFi network with the required signal strength to make a call over the internet without a significant drop in quality compared to regular carrier-based calling.

WiFi calling is advantageous over standard carrier calling as it provides better quality audio and a more stable call overall. You’re not charged any money for it as you’re going over the internet instead of your carrier’s network. Any charges associated with WiFi calling are already covered in your internet bill. 

Is com.sec.unifiedwfc malware?

It’s common practice for threat actors to disguise malware as legitimate services whether they’re made for Android, Windows or any other platform. However, since Samsung makes the package, you can rest assured that it’s safe to use.

While we don’t recommend disabling or removing it, should you want not to use the package, all you have to do is disable WiFi calling on your phone.
