BlackBerry’s BBM allows you to share what music you’re listening to on your device’s media player by displaying it in your status update. That seemed like a good idea in the past, but it seems in BlackBerry 10, videos played in your device’s browser trigger its media player, which then activates its “music” update feature. This means any video you’re viewing, especially those that you’d like to keep private, will be shared through your BBM’s status update, which you can see an example of in the image displayed in this article.
Luckily, the feature is turned off by default, but if you activated it with your BlackBerry 10 device, you might want to consider watching these private videos on something that isn’t your BlackBerry Z10.
