What's that star in my notification area?

Welcome to the wonderful, confusing world of Android 5.0 notifications

This question still hits our inbox from time to time, and it's worth a quick reminder. Android 5.0 Lollipop — at least in its current, unadulterated form — changes the way notifications work. Or, more specifically, there are now three ways they'll be presented to you. The firehose is simply called "All." That is, you'll see every notification there is to see in your notification area. You'll get a buzz, or hear the notification tone.

Then there's "Priority," which brings us back to the question at hand. You can designate specific apps as being "Priority," and then you'll get only "Priority" notifications.

So what's a "Priority" notification? And what's it have to do with that start up there? Glad you asked.
