Syncing on a Galaxy Tab 3 with Viber Contacts...

[Michael Formoso]

Hi, I have a Galaxy Tab 3 with Android 4.1.2, and I'm trying to sync my contacts on Viber with my contacts on the tablet. For some reason, Viber isn't on the list of apps that can be added, along with Skype, Microsoft Exchange, etc. to the apps that sync together to consolidate all the contacts. Please help or explain why this is.
