I was chatting to a friend this morning and the last online status showed 'today at 3.13 am' now it shows as 'last online on 14/4/2016! I've text person and called but their phone is off? Could they have been hacked? I contacted viber but it's been 7 hours and I am really worried as the conversations we have had were private etc.. A logical explanation from a tekky would be great thanks.. A status just suddenly cannot go back in time I've used viber for 2 years and this has never happened!??
