We understand the importance of knowing the number of messages that are waiting to be read, bcc. There was a recent software update on 10/10/2017 that did not include a patch to resolve the message counter.
As of 10/18/2017, this is a known issue that is still under investigation by the device vendor. The release date is under review and will be addressed in a future software version.
In the interim, you should be able to go to settings>apps> menu (3dots) uninstall updates to 6.3.7. Power the phone off/on and the message counter should be resolved.
When you hear the buzzing noise, is that for all notifications that come through when your device should be on silent?
