Sign in to your Android Police account Read update Google has uploaded a video about changes in Android O for developers, and it shares some new details about how Notification Channels will work.

Google has made some changes to the way notifications are handheld in Android O including snoozing and notification channels. Here's what they're about.

That older change is imperfect — plenty of apps group their notifications into channels unhelpfully, with vague names like "General" or "Updates" — but for the most part, it's a solid system.

Most Android apps create several notification channels when they're installed. However, there's no guarantee that you will use every single one of them.

WhatsApp, the cross-platform instant messenger owned by Facebook, will finally allow Android users to choose how different types of notification appear.

Android 15 will hide unused notification channels by default, making it easier to manage notifications from apps with lots of channels.

And in Android O, Google is making that even more powerful by allowing apps to group alerts in “ notification channels,” giving users more precise control over what kind of notifications they get.
