I have many groups of friends on Whatsapp, and sometimes it really becomes annoying when you are not interested in chatting in that group but all the other members keep on texting among themselves. You wish you could be able to mute the notifications from that group for few hours, days or a week because all the messages which you do not read keep on getting accumulated as the notifications and moreover your phone will also keep on vibrating.
But to stop the notification, check for the Mute option and then tap it. You will get 3 options to mute the interval, select any one of them appropriately but remember that you can unmute that group at any point of time by following the same process of muting it.
Once the group is muted, you will not receive any sound or visual notification on the screen, i.e. the red colored notification on the application icon will not change due to that group but once you open Whatsapp, you will see the number of unread messages in front of the title of that group.
Through Mute option is available, but it should have been more comprehensive by repeating that schedule again and again over the days. As of now you will have to mute it every day if your group keeps on troubling you at night.
