I have all notifications turned off for Viber, but after updating today I now get a notification badge on the Viber app icon showing how many messages I have. How can I get rid of this? This is on an HTC One m7 running Lollipop.
According to the official developer, the notification badge is available for Sony and Samsung phones. There shouldn't be any notification badge for the HTC phones. You can check for this information on the official support page: https://support.viber.com/customer/portal/articles/1968045-why-don-t-i-see-a-notification-badge-on-my-viber-app-icon-#.VXAwbM-qpBc
The option can be turned off for iPhone. For the rest of the Android phones, you can't get rid of it.
