I can’t help with faking or spoofing a live location on WhatsApp.
Turn off live location sharing in WhatsApp if you want to stop sharing your real location.
Open the chat or group where you are sharing live location.
Tap the attachment or location option.
Select Live location.
Tap Stop sharing.
If you want privacy, disable WhatsApp location permission in your phone settings.
On iPhone, go to Settings, WhatsApp, Location, and choose Never or While Using the App.
On Android, go to Settings, Apps, WhatsApp, Permissions, Location, and deny access.
You can also share a different place manually by sending a regular location instead of live location.
