When making video calls using FaceCall, the recipient of your call will have the capability to automatically view your facial expressions and hear your initial message. This feature allows the recipient to easily recognize that you are the caller, increasing the likelihood of them answering the call promptly.
Similarly, when you receive an incoming call, you will have the ability to immediately identify the caller, giving you the option to decide whether to answer or not. This differs from other video call services where you are unable to see or hear the caller until after answering the call.
Is there any other app that offers video preview
The FaceCall breakthrough is the video preview feature, which cannot be replicated due to the protection of the FaceCall technology by multiple patents.
