The latest WhatsApp feature is generating a lot of duplicate threads on XDA, drowning other threads in the process. Many are also posted in the wrong section. We're closing down all invite threads to keep the clutter down to a minimum. Instead, please use The Consolidated WhatsApp Calling Thread as a consolidated thread for all discussions related to the WhatsApp calling feature and invites. Thank you!
