The Application “Viber” is very popular, but not many people know that this application has got a really useful new feature.
Namely, the ability to use hidden calls. It is enough to select the desired call and select the option “Hide chat”.
“Viber” then offers to pin whereby you can later access the hidden conversation.
This is great news for those, who suspect that someone is secretly picking their mobile phone or for those who want to hide something from the jealous partner.
