If I delete a contact from my phone, will they still see me in WhatsApp - in detail?
When you delete a contact from your phone's address book, it primarily affects the local storage of that information on your device. This action does not directly impact the visibility or presence of your number within the WhatsApp application for other users.
WhatsApp operates independently of your phone’s contact list. It uses its own database to manage and store contacts based on the phone numbers stored in the app itself, rather than relying solely on the device's address book. Therefore, if someone has saved your number in their WhatsApp contact list, they will still be able to see you as a contact within the app even after you have deleted them from your phone’s contacts.
However, it is important to note that deleting a contact from your phone does remove some functionalities related to that contact on your end. For instance, if you try to send a message or call someone whose contact information has been deleted from your phone, you might not see their name displayed and would need to enter the number manually. This limitation is due to the absence of their contact details in your device's local storage.
In summary, deleting a contact from your phone does not alter their ability to see or interact with you on WhatsApp. The app maintains its own records, ensuring that contacts saved within it remain visible regardless of changes made to the device’s address book.
