Viber problem on my iphone 5
I am experiencing some problems with Viber application with regard to non showing of Txt message status & no sounds(notifications) when receiving calls. Also I have problems in placing & receiving calls.( National & international).
My main worry is not being able to hear the phone when someone calls & the status of my messages I send.
My iphone uses latest version of iOS 7.1.1 AND Viber version 4.2
Appreciate your comment & solution to the problem.
