Whatsapp is coming up with new features. Recently, the news came that Whatsapp will give a new button to switch from video call to Audio call. It will not need to cut the call. Now Whatsapp is coming up with another feature. This feature is to give more power to the admin of Whatsapp Group. Whatsapp is now testing a new button in a group chat through which an admin will be able to 'demote' or 'demise' another admin. That is, it will be possible to do this without deleting them from the group and they will not even need to be included in the group again as common group members. Whatsapp is testing this feature on Android (Beta V2.18.12) and iOS app.
Now if a user has to be removed from the admin of Whatsapp Group, then he has to first remove it from the group, after which he has to add to the group again. There is no other way besides this. According to WABetaInfo, the new option is available in the WhatsApp Info section of Whatsapp. You can access the Group Info section by clicking on the three dot appearing in the right side and going to a group chat. In Group Info, you will see an option to deduct an admin from the group as an administrator.
