My wife has the same make and model phone as I do and she has the same exact problem! I did create a ticket with the link you provided and did mention 'Technical Forum' on the channel question. I connect to my bluetooth headset with no problem and also my phone connects to my car without any problem.

Yes, this is Viber specific, since I uninstalled Viber everything works fine. Thanks in advance :)Hello again Viber team, With this information, our development team will hopefully be able to find the source of the problem, and ultimately resolve it.

When you submit the ticket, in the line called: 'Through which channel did you submit your initial inquiry', please make sure to choose 'Technical Forum'. If it is unique to Viber, then we would appreciate if you could take a minute and report the details to our support team using this direct link: Your ticket details

Is this a problem specific to Viber? in other words, are you getting the same behavior from other apps that have similar characteristics?
