Is there a way for a WhatsApp admin to lock the group icon and title? As of this time, any group member can change the group icon or title.
2018 and it's possible!
WhatsApp admins can stop the members from editing group info. The feature appears to be recently added to WhatsApp. While searching, I found that it is functional since version 2.18.135. What I have installed right now is 2.18.141. So, it should be rolled out to everybody by now.
- Open group info.
- Look for the new option "Group Settings".
- Change the Edit group info setting from All participants to Only admins.
I can also read some sites reporting that WhatsApp beta also has a new option where all members can be muted. So, essentially working like a telegram channel where only admins can send messages. Good times ahead!
PS: This question was asked long ago. However, it still ranks well in the search results and I believe that it needs to be updated for the changes WhatsApp has made recently.
