Sometimes you don’t want that people know you are online on Viber or come to know that you have seen their messages. You can easily apply this setting and disable the “seen” status.
For this you have to open the settings and here tap on Privacy. You will get multiple options here, one is the “seen option” you will find a checked mark, uncheck it. Now you are free. Even you can read the sender’s message he will not have an idea either you have read it or not.
Isn’t it easy? Now keep unwanted contacts away from your chat by un marking "seen" option and keep yourself stress-free.
