Facebook-owned WhatsApp is likely to give group administrators more powers where they will be able to restrict all other members from sending text messages, photographs, videos, GIFs, documents or voice messages in case the admin thinks so.
According to WABetaInfo, a fan site that tests new WhatsApp features early, the popular mobile messaging platform has submitted the "Restricted Groups" setting via Google Play Beta Programme in the version 2.17.43

The "Restricted Groups" setting can only be activated by group admininstrators. Administrators can keep sharing media and chatting as normal as they restrict other members.
Once restricted, other members will simply have to read their messages and will not be able to respond. They will have to use the "Message Admin" button to post a message or share media to the group.
The message will need to be approved by the administrator before going through to the rest of the group.
"A group can be restricted once every 72 hours but thanks to the 2.17.430 beta, we discovered that WhatsApp will be finally able to change this value from the server," the website said.
WhatsApp has also announced advanced features, bug fixes and general improvements in the upcoming update.
The features will be available once
