What are notification categories on Android?

Notification categories on Android are a way of dividing an app's alerts into distinct groups, so you can control exactly which types of notifications you receive from that app, and which ones you silence. Instead of choosing between getting all notifications from an app or none at all, Android lets you fine-tune things at a much more specific level. The sections below walk through how they work, how to manage them on your Samsung phone, and how they differ from other notification tools.

How do notification categories work on Android?

Notification categories, officially called notification channels on Android, are individual groups that app developers create to separate different types of alerts. Each category can be turned on or off independently, so you stay in control of what actually reaches you. Think of it like sorting your post into different trays: you can keep the letters you care about and bin the ones you don't.

For example, a banking app might have separate categories for transaction alerts, promotional offers, and security warnings. You can keep the security alerts switched on while turning off the promotional messages entirely. Android introduced this system to give users much more precise control, moving away from the all-or-nothing approach that made notification management frustrating for so many people.

Each notification category also carries its own settings. You can choose whether a category makes a sound, shows a pop-up banner, appears silently in your notification shade, or is blocked completely. This means two different categories from the same app can behave in completely different ways, based on what matters most to you.

Why do some apps have more notification categories than others?

The number of notification categories an app has depends entirely on the app's developers. Apps with a wider range of features and content types naturally need more categories to cover all the different alerts they send. A simple alarm clock app might have just one or two categories, while a social media or shopping app could have ten or more.

Developers decide how to group their notifications during the app's design process. A well-designed app will split its alerts into logical, meaningful categories so users can make sensible choices. A poorly designed app might lump everything into a single category, which gives you less flexibility.

It is also worth knowing that Samsung's own apps, like Samsung Messages, Samsung Health, and Galaxy Store, tend to have clearly organised notification categories that reflect the range of things those apps do. This makes it easier to keep the alerts you actually want without being bombarded by ones you don't.

How do you change notification categories on a Samsung phone?

On a Samsung phone running One UI, you can change notification categories directly through the Settings app in just a few steps. The process is straightforward and does not require any technical knowledge.

1. Open the Settings app on your Samsung phone.
2. Tap Notifications.
3. Tap App notifications and select the app you want to adjust.
4. You will see a list of that app's notification categories. Tap any category to expand its options.
5. Toggle individual categories on or off, or adjust how each one behaves, such as whether it makes a sound or shows a banner.

You can also reach an app's notification settings quickly by long-pressing a notification when it appears on your screen, then tapping the settings icon that appears. This takes you straight to the relevant category, which is handy if a specific type of alert is bothering you and you want to deal with it on the spot.

One UI makes this process especially accessible because it labels each category clearly and groups the options in a logical order. Even if you have never dug into notification settings before, it should feel manageable within a minute or two.

What happens when you turn off a notification category?

When you turn off a notification category, you stop receiving all alerts that belong to that specific group, permanently, until you switch it back on. The app itself continues to work normally; you simply will not be interrupted by that particular type of alert anymore. No sound, no banner, no badge: those notifications are blocked entirely.

Importantly, turning off one category does not affect any other categories from the same app. If you disable promotional notifications from a shopping app, for instance, you will still receive order updates and delivery alerts if those belong to separate categories and remain switched on.

It is also worth noting that some notification categories are marked as important by the app and cannot be turned off. These are usually tied to critical functions, like security alerts or account warnings, where the developer has decided the information is too important to block. If you see a category that cannot be toggled, this is why.

What's the difference between notification categories and Do Not Disturb?

Notification categories and Do Not Disturb (DND) are two separate tools that work at different levels. Notification categories permanently filter which alerts an app is allowed to send you at all. Do Not Disturb is a temporary mode that silences alerts across your entire phone for a set period, without changing any of your permanent notification settings.

Here is a simple way to think about the difference:

• Notification categories decide what your phone is allowed to show you, all the time.
• Do Not Disturb pauses interruptions temporarily, for example, during a meeting or while you sleep, but does not delete or change your category settings.

When Do Not Disturb is turned off, all your notifications return to behaving exactly as your category settings dictate. The two tools complement each other well. You might use notification categories to permanently silence marketing alerts you never want, while using Do Not Disturb to get a few hours of uninterrupted quiet without changing anything permanently.

On Samsung phones, you can customise Do Not Disturb through Settings > Notifications > Do Not Disturb, where you can also set exceptions, allowing calls from specific contacts to come through even when DND is active. This makes it a flexible tool for managing your focus without losing access to genuinely urgent alerts.
