How to remap Bixby button on Galaxy S9 and S9+ after updating to Android Pie?

You can now map the single or double press gesture of the Bixby key to a third-party app or a quick command.

After the February update of Bixby (version 2.1.04.18), you can now remap Bixby button to an app or a Bixby quick command.

This Galaxy S9 Android Pie update guide explains the new features of Bixby in Android Pie update, and how to remap the Bixby button to other apps or a quick command.

New gestures for the Bixby button on Galaxy S9 and S9+ after updating to Android Pie

Traditionally, the Bixby button in Galaxy S9, S9+, S8, S8+, Note 8, and Note 9 only supports one gesture: press.

You can choose to press to open Bixby (Bixby Home), or do nothing (this essentially disables the Bixby button). Of course, you cannot remap the press gesture to anything else, or disable Bixby in your phone.

In Android Pie update for Galaxy S19, S9+, Note 9, Note 8, S8, and S8+, Bixby was updated to a new version with new gestures for the Bixby button. Now, the Bixby button supports 3 gestures:

Single press.
Double press.
Long press.

The long press is reserved for Bixby Voice command. You cannot change it. When you long press the Bixby button, you can continue with voice commands immediately.

The single press OR the double press MUST be assigned to Bixby Voice page. For example, if you assign the single press to Bixby Voice, then you can customize (remap) the double press to something else.

Please note, Bixby Voice page, which is different from Bixby Home, is new in Galaxy S9 Android Pie update. Bixby Home still exists in Galaxy S9 Home screen, and you can still hide it if you want.

Major changes of Bixby in Android Pie update for Galaxy S9, S9+, S8, S8+, Note 8, and Note 9

In Android Pie update for Galaxy S9, S9+, S8, S8+, Note 8, and Note 9, Bixby Service, Bixby Voice, and Bixby Vision, were bumped to version 2.1.x, and Bixby Home to version 3.x.

The major changes of Bixby in the Android Pie update include:

New gestures for the Bixby button. Remapping the Bixby button to third-party apps was added in February update of Bixby.
New Bixby quick commands.
New Bixby Vision integration in the new camera app.
New Bixby Voice page (showing tips, features, and suggestions for Bixby Voice, and accessing Bixby Voice settings).

You can update Bixby in Galaxy Store.

How to use the lockdown mode on Galaxy S9 and S9+ with Android Pie update?

Everything you need to know about Android Pie lockdown mode on Galaxy S9 and S9+

simon · Leave a Comment

You can use Android Pie lockdown mode on Galaxy S9 and S9+ with Android Pie (Android 9) update to temporally disable biometric unlock and smart lock. PIN or password will be required to unlock the phones.

The lockdown mode is a standard security feature in Android Pie (Android 9). Luckily, Samsung did not mess up this feature in the One UI.

This Galaxy S9 Android Pie update guide explains everything you need to know about the lockdown mode on Galaxy S9 and S9+ with Android Pie update and shows you how to use it.

You may also check this updated guide on using lockdown mode on Galaxy S9, S10, S20, S21, and S22.

What is the lockdown mode on Galaxy S9 and S9+ with Android Pie update?

If enabled, Galaxy S9 and S9+ offer many ways to unlock the phone.

In addition to PIN/password/pattern, you can also unlock Galaxy S9 and S9+ using:

Fingerprints.
Iris.
Face.
Trusted devices, trusted places, trusted faces, and matched voices through the smart lock.

All these additional unlock methods are provided for your convenience. Many Galaxy S9 and S9+ owners enjoy these fast unlock methods.

However, in some special situations, for example, someone attempts to force you to unlock the phone to get your data, you may try to disable these unlock methods temporally (and quickly), then type the wrong password/PIN a few times so that you have to wait longer and longer to try again.

When the lockdown mode is enabled, notifications will not be shown on the Galaxy S9 lock screen.

The lockdown mode is one of the new features in Android Pie. Samsung kept the stock feature and did not mess it up this time in the Android update for Galaxy S9 and S9+, unlike what they did to the navigation gestures.

How to enable the lockdown mode on Galaxy S9 and S9+ with Android Pie update?

By default, the lockdown mode on Galaxy S9 and S9+ with Android Pie update is not enabled.

You need to enable it in the power button options (power menu) before you can use it.

How to use a USB flash drive on Galaxy S9 and S9+?

You can use a USB flash drive or even a 2TB USB drive to expand Galaxy S9 storage

simon · 7 Comments

A USB flash drive is often the most convenient tool to quickly share files between Galaxy S9, Galaxy S8, Galaxy S10, Galaxy S20 and other devices.

So, in addition to using a micro SD card, you can further expand Galaxy S9 and other Galaxy phones storage with a USB storage.

This Galaxy S9 guide explains when you need to use a USB flash drive, the limitations of using USB storage on Galaxy S9 and other Galaxy phones, how to use and manage USB storage on Galaxy S9 and S9+.

Since Galaxy S8, Samsung has moved to USB-C port on all Galaxy S and Galaxy Note phones. So, this guide applies to all Galaxy phones with USB-C port, including Galaxy S8, Galaxy S9, Galaxy S10, Galaxy S20, Galaxy Note 8, Galaxy Note 9, Galaxy Note 10, and Galaxy Note 20.

In this guide, we use SanDisk Ultra Dual Drive in some examples. You may get a detailed guide on how to use SanDisk Ultra Dual Drive here.

When do you need to use external USB storage on Galaxy S9 and S9+?

Although you can expand Galaxy S9/S9+ storage with a micro SD card as explained in this guide, sometimes you may find you have to use a USB flash drive or using a flash drive is more convenient than other tools/methods.

For example, if you use two SIM cards on Galaxy S9 or S9+, you then cannot use the micro SD card because slot 2 in the SIM card tray was used by the SIM card already.

Or if you want to share some large videos on your phone with others and you do not want to hand over the phone to that person, you can then directly transfer files from Galaxy S9 to a USB flash drive, or even an external USB drive.

Or when you want to transfer some large files between Galaxy S9 and the PC/notebook without using the USB cable, then a USB flash drive probably is the fastest solution.

Some Galaxy S9 owners also use a USB flash drive to save offline videos and music files. They can use the drive on multiple devices without making copies on each device.

What are the limitations of using a USB flash drive on Galaxy S9 and S9+?

Although a USB flash drive is a plug-and-play (PnP) device, sometimes you may find the USB flash … Read the rest

DeX Pad features a smaller footprint than its predecessor (DeX Station). And one of the significant changes is your phone can lay down on the DeX Pad. So, it is very easy to use the phone screen as a touchpad.

Samsung DeX Pad works with all DeX-enabled devices: Galaxy S9, S9+, S8, S8+, Note 8, Note 9 and Tab S4. It also offers identical Samsung DeX features as the DeX Station and DeX cable.

Samsung DeX Station (aka multimedia dock).
Quick start guide in multiple languages.

So, you need to prepare the following items to use Samsung DeX Station:

An HDMI cable.
(optional) A USB (or wireless) mouse/keyboard. You can use the phone screen as the trackpad. But unlike Samsung DeX Pad,

Everything you need to know on powering on, powering off and rebooting Galaxy S9 and S9+.

simon · Leave a Comment

You may already know to use the power button to power on, power off and reboot Galaxy S9 or S9+.

But occasionally, the power button may be not working as expected. You may have to use button (key) combinations to power off, power on or restart Galaxy S9 or S9+.

This Galaxy S9 guide explains how to reboot, power on and power off Galaxy S9 and S9+ in both normal situations and abnormal situations (e.g. when Galaxy S9 or S9+ hangs.).

Please note, in this guide, we do not differ reboot and restart. They are used interchangeably.

Why do you need to reboot Galaxy S9 or S9+ periodically?

You may know you have to reboot Galaxy S9 when you update the phone (for example, updating Galaxy S9 or S9+ to Android Pie). In this case, some system files being used have to be replaced. Therefore, you need to “stop” the system, then restart the system with the updated files.

For apps, normally, it is not necessary to reboot Galaxy S9 if you update them. Apps in Android are running in its own container. The system can destroy the container and then reload the app with updated apps on Galaxy S9 or S9+. Therefore rebooting Galaxy S9 or S9+ is generally not required for updating apps on the phone.

But some tech guys may tell you to reboot Galaxy S9 or S9+ periodically (from once a month to once a week, NOT daily) to make the phone more responsive.

This is actually a valid suggestion.

When you reboot Galaxy S9 or S9+, all app leftovers (some apps sometimes may fail to clean up their own files after you close them) and ghost processes will be cleaned.

How to automatically reboot Galaxy S9 or S9+?

Samsung added the feature of “auto restart” feature in Galaxy S9 and S9+.

You can enable auto restart on Galaxy S9 and S9+ in Settings — General management — Reset— Auto Restart.

As shown in the screenshots below, you can enable auto restart so that Galaxy S9 or S9+ will be rebooted automatically within one hour of the specified time.

You can only set the schedule as once a week only. Frequently restarting/rebooting Galaxy S9 and S9+ will not be helpful.

This Galaxy S9 how-to guide explains to you how to use them and how to use scroll capture to take screenshots on Galaxy S9 and S9+

Why do you need to take screenshots on Galaxy S9 and S9+?

Sometimes, you may need to keep a record of a conversation, to share a webpage, to show some locations on Google maps to others, or to record some transactions when you are using the Galaxy S9 or S9+.

A screenshot is the easiest and the most effective way to keep info and pieces of evidence. The image saved can be read on almost any devices.

Although you can edit them after you take screenshots on Galaxy S9 and S9+, most people give more trust in screenshots than the text you typed.

Sometimes, if you want to report a problem of an app, or request technical services, you may be asked to take some screenshots so that the technical staffs can understand the problem quickly.

How to take screenshots on Galaxy S9 and S9+ without using any apps (and without using your PC)?

There are at least 5 ways to take screenshots on Galaxy S9 and S9+ without using any apps:

Using hardware buttons (volume down + power button).
Palm swipe.
Using the Assistant menu.
Using Bixby voice command.
Using Google Assistant.

This guide will show you the details of these 5 methods in the following sections individually.

Method 1: use hardware buttons to take screenshots on Galaxy S9 and S9+

You can take a screenshot on Galaxy S9 and S9+ by pressing the holding Power button and Volume down button simultaneously, as illustrated below. You should hear a click /shutter sound once screenshot is taken.

How to use Galaxy S9 safe mode on Galaxy S9 and S9+?

Galaxy S9 safe mode guide: what is Galaxy S9 safe mode? when you need it? how to enter Galaxy S9 safe mode? how to use it?

simon · Leave a Comment

You can use Galaxy S9 safe mode to identify possible causes of some problems or strange behaviours of Galaxy S9 and S9+.

This safe mode is safe for your data, settings and apps. They will not be affected or altered when using the safe mode on Galaxy S9 and S9+.

What is Galaxy S9 safe mode? And when do you need Galaxy S9 safe mode?

Like most other Android phones, Galaxy S9 and S9+ have a special Galaxy S9 safe mode letting you troubleshoot possible problems caused by third-party apps.

In Galaxy S9 safe mode, all third-party apps installed by you were temporally disabled so that you can determine whether the problem is caused by such apps.

Your data, settings, and app data are not affected when you reboot Galaxy S9 or S9+ into Galaxy S9 safe mode

Galaxy S9 safe mode can only determine whether some strange behaviours or problems are caused by third-party apps. It is not able to pinpoint the app.

Unlike Galaxy S9 recovery mode which is not part of Android OS, Galaxy S9 safe mode is a special mode of Android OS.

So, under the Galaxy S9 safe mode, you can still make and receive calls, connect to the Internet, use pre-installed apps. The safe mode only prevents you from using apps installed by you.

You need to try Galaxy S9 safe mode before you visit the service centre because technical support in most service centres does not solve issues due to third-party apps. They only diagnose problems in the firmware and pre-installed apps.

Although Galaxy safe mode does not change your data and settings, you may lose some home screen customizations after you exit the safe mode. So, you may still consider to back up Galaxy S9 before rebooting into the safe mode.

How to reboot into Galaxy S9 safe mode?

There are two ways to reboot into Galaxy S9 safe mode:

Use the power button options if Galaxy S9 or S9+ is currently powered on.
Use buttons if the phone is powered off.

Method 1: Use power button options to reboot into Galaxy S9 safe mode

simon · 2 Comments

Although most Galaxy S9 touchscreen gestures work on all other Android phones, you may not be aware of some gestures that help you use Galaxy S9 and S9+ effectively.

This Galaxy S9 how-to guide illustrates the 7 Galaxy S9 touchscreen gestures with animations, explains the features of these gestures and gives examples of using these gestures.

What are Galaxy S9 touchscreen gestures?

As Galaxy S9 and S9+ do not have a physical keyboard or other input devices, you have to interact with the phone either through the touchscreen or voice (e.g., Bixby or Google Assistant).

In addition to the on-screen keyboard or keypad, Galaxy S9 and S9+ also accept some touchscreen gestures.

When your finger(s) or other capacitive pens (please note S Pen on Galaxy Note devices does NOT work with Galaxy S9 or S9+ screen) move on the screen, Galaxy S9 and S9 can recognize certain patterns and therefore responds accordingly.

These moving patterns are usually referred to as Galaxy S9 touchscreen gestures.

So, understanding and correctly using Galaxy S9 touchscreen gestures are essential if you want to use the phone efficiently.

Similar to other Android phones, there is nothing special in Galaxy S9 touchscreen gestures. These gestures can be used in almost all other Android phones.

Although most of Galaxy S9 touchscreen gestures are used on the screen, some can also be used on the physical buttons. e.g., the power button accepts press, double press and long press gestures.

List of Galaxy S9 touchscreen gestures in Galaxy S9 and S9+

You can use the following 7 Galaxy S9 touchscreen gestures on Galaxy S9 and S9+ for various operations.

Tap is one of the most used Galaxy S9 touchscreen gestures.

Some example of using tap gesture includes:

You can open an app by tapping an app icon in Galaxy S9 home screen or

How to reboot into Galaxy S9 recovery mode and to clear Galaxy S9 cache partition on Galaxy S9 and S9+?

simon · 8 Comments

You can use Galaxy S9 recovery mode to flash new ROMs, clear Galaxy S9 cache partition, and to check recovery logs.

Although Galaxy S9 recovery mode was designed for some advanced users, you may need some of the features, especially clearing the cache partition to fix some problems after a major update.

This Galaxy S9 guide explains to you the functions of Galaxy S9 recovery mode, the way to reboot Galaxy S9 or S9+ into recovery mode, usage of the recovery mode, and methods of clearing Galaxy S9 cache partition.

What is Galaxy S9 recovery mode?

All Android phones have a special mode: recovery mode, which allows you to fix any Android problems and perform some actions (for example, patch the system) to the Android system without loading Android OS.

In the phone storage layout, there is a special partition for recovery. This partition is protected from Android OS and other partitions.

Galaxy S9 is not an exception.

If you think you never used Galaxy S9 recovery mode, you are very likely wrong.

When you install updates (including monthly security updates) for Galaxy S9 and S9+, you may notice the phone will reboot twice automatically.

During this updating process, Galaxy S9 or S9+ would reboot into Galaxy S9 recovery mode first to apply the update, then reboot into Android OS so that you can use Galaxy S9 and S9+.

Of course, Galaxy S9 recovery mode offers more functions including:

To apply Android OS update
To reset (factory data reset) Galaxy S9 or S9+.
To wipe/clear Galaxy S9 cache partition.
To boot into bootloader (download mode).
To flash official or third-party ROMs for Galaxy S9 and S9+.
To mount /system partition manually.
To check recovery logs.
To run a graphics test.

Although Galaxy S9 recovery mode is seldom used for most Galaxy S9 and S9+ owners, you may need to reboot into Galaxy S9 recovery mode to fix some problem with your S9 or S9+.

In fact, most Galaxy S9 and S9+ owners reboot the phone into Galaxy S9 recovery mode to clear the cache partition to fix some issues after a major Android update.

You should not confuse Galaxy S9 recovery mode with Galaxy S9 safe mode, which is a special mode of Android OS.

How to disable Bixby button in Galaxy S9 and S9+?

You can disable both the press and long press gesture of Bixby button in Galaxy S9 and S9+ to disable Bixby button in Galaxy S9 and S9+.

simon · 19 Comments

Some Galaxy S9 and S9 owners are not excited about Samsung Bixby and the dedicated button. They may want to disable Bixby button in Galaxy S9 and S9+.

You can easily disable Bixby button in Galaxy S9 and S9+ if you frequently pressed the button inadvertently, or if you do not want to use Bixby.

Update: After updating Galaxy S9 or S9+ to Android Pie, you cannot disable the Bixby button. Instead, you can remap the Bixby button to any third-party apps or any Bixby quick commands.

This Galaxy S9 guide explains the functions of Bixby button in Galaxy S9 and S9+, and shows you how to disable Bixby button in Galaxy S9 and S9+.

What is Bixby button? Why may you want to disable Bixby button in Galaxy S9 and S9+?

Since Galaxy S8 (and S8+), Samsung added a dedicated button for Bixby with the hope of boosting the usage of Samsung’s AI assistant.

As shown in Galaxy S9 and S9+ layout, Bixby button is located on the left side of the phone below the volume keys.

By default,

If you press the Bixby button on Galaxy S9 or S9+, the phone will open Bixby Home.
If you long press (press and hold) the Bixby button, the phone will open Bixby Voice.

Samsung does not allow you to map the Bixby button on Galaxy S9 and S9+ to any other apps. It can only be used for Samsung Bixby unless you root the phone and mess up a few system settings.

Although Samsung Bixby has been dramatically improved since the initial release with Galaxy S8, in many aspects, it is still not comparable to Google Assistant, which can be enabled in Galaxy S9 or S9 by long tapping (tap and hold) the Home button. Some Galaxy S9 and S9+ owners may not want to use Samsung’s Bixby at all. They are happy with Google Assistant.

Some other owners may do not use either Google Assistant or Bixby. But they may press the Bixby button accidentally when they want to press the volume button or the power button.

Even some Bixby users may not want to use the Bixby Home, which comes out when you press the Bixby button. You can use other Bixby features without the button.

If you are not sure whether your existing SIM card can be used in Galaxy S9 and S9+, please post your question in the comments box below.

We will check it for you.

You MUST use the correct size of Galaxy S9 SIM card because the slot in the Galaxy S9 SIM card tray can only hold nano-SIM cards.

In theory, there are four possible sizes of SIM cards:

Full-sizeSIM (1FF). Full-size SIM is “giant” in size: 85.60 mm × 53.98 mm × 0.76 mm. No Android phones used it.
Mini-SIM (2FF). Mini-SIM usually is now often referred as “big” or “normal” or “standard” SIM card in some countries. Most carriers and phone manufacturers phased out mini-SIM a few years ago. Very few Android phones in the market now use this big SIM card.
Micro-SIM

How to use Galaxy S9 home screen landscape mode?

simon · 8 Comments

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 addition, you can also lock the layout of Galaxy S9 home screen in Android Pie update as explained in this guide.

What is Galaxy S9 home screen landscape mode?

By default, the home screen (and apps screen) was always in portrait mode on most Android phones even if you hold the phone horizontally, and if you turn on auto-rotate.

So, it is hard to use the home screen in landscape mode, and you may have to hold the phone in portrait orientation to use the home screen and apps screen.

Please do not confuse this limitation in home screen with the auto-rotate.

Most apps including system apps like Settings support landscape mode for a long time. When you turn on auto-rotate, you can use most apps in the landscape 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.

In a nutshell, Galaxy … Read the rest
