Why can't I see who is calling on the phone in WhatsApp - in detail?

The inability to see who is calling on a phone through WhatsApp is primarily due to the app's design and privacy settings. WhatsApp, developed by Meta (formerly Facebook), prioritizes user privacy and security. When you receive a call on WhatsApp, your phone will display the caller's name or number only if it is saved in your contacts. If the number is not saved, you will see an unknown or private number. This feature ensures that users have control over their personal information and can decide who has access to their contact details. Additionally, WhatsApp encrypts calls to protect user data from unauthorized access, further enhancing privacy. By default, WhatsApp does not display the caller's name or number during a call to maintain this high level of security and privacy.
