This Galaxy S9 guide answers all questions you may have on using two SIM cards on Galaxy S9 and S9+.

Is your Galaxy S9/S9+ capable of using two SIM cards?

If you bought your Galaxy S9 or S9+ in the US, very likely, it is a single SIM phone only. You cannot use two SIM cards on these phones sold in the US (through carriers and official distributors).

In most international markets, your Galaxy S9 or S9+ is very likely a dual-SIM version. And therefore, you may use up to two SIM cards on the phone.

You should always check with the seller on whether you can use two SIM cards on the phone you want to buy.

You can also check the Galaxy S9 box to see whether the Galaxy S9 or S9+ is dual SIM or single SIM version.

In most regions, the dual-SIM capability is usually marked as “duos” on the left side of the official Galaxy S9 box as shown below.

The dual-SIM Galaxy S9 and S9+ are dual standby only, not dual active. This means both SIM cards are reachable when in the standby mode.

Understand and use Galaxy S9 notification number badge (notification dots, app icon badge)

Galaxy S9 notification number badge (notification dots, app icon badges) is entirely different from the old number badge. This guide shows you the detail.

simon · 18 Comments

If you upgraded your old Galaxy phone to Galaxy S9 or S9+, you might be frustrated with the new Galaxy S9 notification number badge (notification dots, aka Galaxy S9 app icon badges).

This Galaxy S9 guide explains the differences between Galaxy S9 notification number badge (notification dots) and the old number badge and shows you how to customize Galaxy S9 notification number badge (notification dots).

What is Galaxy S9 notification number badge (notification dots)?

For example, as shown below, when you have 3 notifications for the Internet app (browser app), you will find the number (3) in the top right of the browser app icon.

This number badge is usually referred to as Galaxy S9 notification number badge. In old Galaxy phones, there has been a number badge which looks similar to Galaxy S9 notification number badge.

Because Galaxy S9 notification number badge corresponds to notification dots in stock Android, the notification number badge was sometimes referred as Galaxy S9 notification dots.

If you think the new Galaxy S9 notification number badge (notification dots) is just a beautified version of the old number badge, you are then totally wrong.

What are the differences between Galaxy S9 notification number badge (notification dots) and the old number badge?

Although they look similar, Galaxy S9 notification number badge and the old number badge are two entirely different things.

This Galaxy S9 guide explains the differences between Galaxy S9 status icons and notification icons, and the meaning of these icons in the status bar in Galaxy S9 and S9+.

What is the difference between Galaxy S9 status icons and notification icons?

Android uses the top of the screen as the status bar, where Galaxy S9 status icons and notification icons are shown. It applies to Galaxy S9 Home screen, lock screen and all apps.

The following screenshot is an example of the Galaxy S9 status bar with notification icons on the left and status icons on the right. When you use Galaxy S9 home screen landscape mode or any apps in landscape mode, the status bar is also in the top of the screen.

Galaxy S9 status icons and notification icons give you quick info about the system status (e.g., mobile network signal strength) and notifications from apps or the system.

When an app is in the immersive full-screen mode, the status bar will be hidden temporally. In this case, you can swipe down from the top of the screen to bring up Galaxy S9 status bar (and Galaxy S9 navigation bar as well)

The differences between Galaxy S9 status icons and notification icons include:

Galaxy S9 status icons are always related to the system; while Galaxy S9 notification icons are always linked to specific apps (including a few system apps and third-party apps).
Galaxy S9 status icons are normally shown on the right side of the status bar; while Galaxy S9 notification icons always appear on the left side of the status bar.
Galaxy S9 status icons are more or less universal in all regions; while Galaxy S9 notification icons depend on individual apps, whose developers can use whatever they want.

Typically, when you see an icon on the left side of the status bar in Galaxy S9 or S9+, there are usually at least one or more corresponding notifications in Galaxy S9 notification panel.

But if you see a Galaxy S9 status icon, there is seldom a corresponding notification.

Samsung added the Galaxy S9 home screen landscape mode in Galaxy S9 and S9+.

You can change Galaxy S9 home screen to landscape orientation when you hold Galaxy S9 and S9+ horizontally. Of course, this also applies to Galaxy S9 apps screen (app drawer), which essentially is a special home screen.

This Galaxy S9 guide explains what Galaxy S9 home screen landscape mode is, how to enable and disable Galaxy S9 home screen landscape mode, and how to use Galaxy S9 home screen landscape mode.

Update: in Android Pie update for Galaxy S9 and S9+, you can use the rotation toggle button to quickly change and lock screen orientation, including the home screen. You may check this guide on using the rotation toggle to change and lock the Galaxy S9 screen orientation.

In Android tablet, since Android Honeycomb 3.0, the home screen landscape mode has been supported.

However, on the phone, the home screen landscape mode is still new.

The larger screen aspect ratio beyond 16:9 in many recent flagship Android phones exacerbates the implementation of landscape mode for the home screen. The screen simply looks too narrow for the icons.

Anyway, Samsung now offers the option to use Galaxy S9 home screen landscape mode in Galaxy S9 and S9+.

This means the Galaxy S9 home screen can automatically rotate to landscape mode when you hold the phone in landscape position.

Undoubtedly, the app icons and widgets in Galaxy S9 home screen will be re-organised in landscape mode. Simple rotation is not enough due to insufficient height in the landscape mode.
