Hi!
My friend is using viber for android for a while ago.
When I enter on viber and check if he is online, his status is mostly like "last seen X minutes ago." . What is interesting is that mostly in the day his status changes from 10 to 10 minutes, from "last seen 10 minutes ago" changes automatically to "last seen 1 minute ago". What does this mean? That he has his internet connection on always? because even at night his status changes from 10 to 10 minutes, it's like he is never sleeping or something. Altough, I must mention that there are periods in the day when his status is "last seen 1:03 pm" for example, and it doesn't change so quickly from 10 to 10 minutes, it changes after one or a couple of hours. I find it very odd that he has periods when he doesn't enter for couple of hours, like a normal person, but then, mostly his status changes from 10 to 10 minutes exactly.
