a community for owners of Samsung Galaxy S9 and S9+

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.

So, there are sizeable Galaxy S9 and S9+ owners who may want to disable … Read the rest

Android Pie update for Galaxy S9 and S9+ allows you to lock Galaxy S9 home screen layout so that you will not lose you customization due to accidental touches.

Although it sounds trivial and can be found in some other Android phones, many Galaxy S9 and S9+ owners will find this is one of the very useful features of Android Pie update for Galaxy S9 and S9+.

This Galaxy S9 Android Pie update guide shows you how to lock Galaxy S9 home screen layout on Galaxy S9 and S9+ with Android Pie update, and what the caveats are if you lock the home screen layout.

Why you may need to lock the home screen layout?

You can customize the Galaxy S9 home screen in many ways. You can use third-party themes, remove Bixby Home from the home screen, change wallpapers, adjust the grid layout, add app folders, pin individual files to the home screen, show photos on Galaxy S9 home screen (using widgets), and manage home screen panels.

Besides, Galaxy S9 and S9+ also support landscape mode of the Galaxy S9 home screen.

But very easily, the customization can be instantly wiped by accidental taps.  For example, your kids may delete the widgets from the screen if they get their hands on the screen.

Many Galaxy S9 and S9+ owners want to lock the customization after the initial setup because most owners seldom change the home screen after one or two months.

Now, in the Android Pie update for Galaxy S9 and S9+, you can lock Galaxy S9 home screen layout so that you will not lose your customization so easily.

Of course, it only locks the layout. You cannot add or delete app icons or widgets once you lock Galaxy S9 home screen layout. But you can still use Galaxy S9 home screen edit mode to customize the home screen.

You can transfer and migrate data to Galaxy S9 and S9+ from iPhones or Android phones through a USB cable, or wireless connection, or cloud storage.

For many Galaxy S9 and S9+ owners, Galaxy S9 or S+ is not your first smartphone. You were very likely using an iPhone or an Android phone before getting Galaxy S9 or S9+.

This Galaxy S9 guide explains to you how to transfer and migrate data to Galaxy S9 and S9+ if you were using 1). an iPhone; or 2). a Samsung Galaxy phone, or 3). other Android phones.

What can be migrated to Galaxy S9 and S9+?  What cannot be?

Contacts, messages, call logs, photos, videos, music files, documents and stock calendar data in your old phone can be easily transferred and migrated to Galaxy S9 and S9+.

If you want to migrate data to Galaxy S9 from an iPhone, of course, apps cannot be transferred.  There is no one-to-one match in Google play store and Apple’s App Store.  Some app developers only release apps in App Store. Some may only release them in the Google Play store.

If you want to migrate data to Galaxy S9 from a Samsung Galaxy phone, then you can transfer and migrate almost all data. Apps from Galaxy apps and side-loaded apps can be transferred as well.  Phone settings including WiFi, wallpaper, home screen settings, and some system settings, will be migrated. The only data that cannot be transferred or migrated are some game progress data and login credentials (unless you use the Samsung Pass). Your email settings in the stock email app can also be migrated. But you need to re-enter the password for each account.

If you transfer and migrate data to Galaxy S9 or Note 9 from other Android phones, some phone settings will not be copied. Some side-loaded apps may also be ignored.

Transfer and migrate data to Galaxy S9, S9+ or Note 9 from an iPhone

In Android Pie update for Galaxy S9 and S9+, Samsung keyboard can be in the floating mode, and therefore, you can put the keyboard anywhere on the screen and use the keyboard on Galaxy S9 and S9+ flexibly.

The floating keyboard on Galaxy S9 and S9+ with Android Pie update works on all apps, once enabled.

This Galaxy S9 Android Pie update guide explains how to enable, use, and customize the floating keyboard on Galaxy S9 and S9+ with Android Pie update.

Please note, the Writing Assistant on Samsung Keyboard requires the Android 12 update, which Galaxy S9 will not get. You have to use the third-party keyboard if you need the grammar check (in addition to the spelling check).

What is the new resizeable keyboard on Galaxy S9 and S9+ with Android Pie update?

By default, the Samsung keyboard or keypad is fixed on the bottom of the Galaxy S9 or S9+ regardless of the orientation (portrait or landscape) of the phone, just like in other Android phones.  The screen area occupied by the keyboard will not be used by the app.

This means the keyboard may waste a lot of screen space for the app.

When you hold the phone is the landscape mode (FYI, Galaxy S9 Home screen supports landscape mode as well), the keyboard will have to stretch a lot and waste even more screen space. So, the screen size is not fully utilized.

The problem has been exacerbated in the last few years because the aspect ratio of smartphones has become larger and larger.

Of course, the solution already exists on some Samsung tablets: using a freely resizable keyboard.

Now, in Android update for Galaxy  S9 and S9+, Samsung brought the resizeable (free form) to Galaxy S9 and S9+ so that you can type easier.

The floating keyboard allows you:

• To let the keyboard poping over any apps when using it. Therefore you will get more usable screen space when using the keyboard.
• To put keyboard anywhere you want.
• To relocate the keyboard when you typing.
• To resize the keyboard  (subject to minimum and maximum size).
• To switch back to standard mode (fixed mode) at any time.
• To switch back to the one-handed keyboard,

Basically, if you feel the keyboard affects your usage of any apps, you should try the floating keyboard after updating Galaxy S9 … Read the rest

Samsung revamped the Recents screen in Android Pie update for Galaxy S9 and S9+ to align some features with the stock Android Pie.

However, the difference between the overview screen in the stock Android Pie and the Recents screen in Galaxy S9 and Galaxy S9+ with Android Pie update is significant.

This Galaxy S9 Android Pie update guide explains the new features in the Recents screen in Android Pie update for Galaxy S9 and S9 Plus, how to use the new Recents screen gestures, how to dismiss individual app, and disable suggested apps in the Recents screen.

What’s new in the Recents screen in Android Pie update for Galaxy S9 and S9 Plus?

In the Samsung Galaxy phones, the Recents screen is usually called Overview screen in the stock Android. Correspondingly the overview button in the stock Android is Samsung’s Recents button.

Basically, the Recents (overview) screen lists all recently used apps. You can quickly re-open them, or open them in the multiwindow mode (both in the split-screen and pop-up views).

Android Pie (Android 9) revamped the Overview screen to stack the list horizontally (instead f vertically as in previous versions of Android) to work better with the new Android Pie navigation gestures.

In Android Pie update for Galaxy S9 and S9+, Samsung adopted its own full-screen navigation gestures and own Overview screen design.

Compared to Galaxy S9 and S9+ with Android Oreo,  Android Pie update for Galaxy S9 and S9+ made has a different Recents screen:

• A row of suggested apps is added by default on the Overview screen. Of course, you can disable the suggested apps on the Recents screen (read on).
• Some multiwindow features were removed. For example, you cannot find the snap window feature on Galaxy S9 and S9+ with Android Pie update.

• There is no list view of apps. You have to use the thumbnail view.

After unboxing Galaxy S9 or S9+, you may want to charge Galaxy S9 battery so that you can start to set it up and use it.

When Samsung Galaxy S9 and S9+ left the factory, the battery is charged to about 50% of the capacity, which is sufficient for you to inspect the phone on the counter.

Because the only difference between Galaxy S9 battery and Galaxy S9+ battery is the size (capacity), charging Galaxy S9 battery is identical to that for Galaxy S9+. Therefore, we use Galaxy S9 to refer to both Galaxy S9 and S9+.

Two ways to charge Galaxy S9 battery

You can charge the Galaxy S9 battery in two ways:

1. Using a USB cable (USB charging).
2. Using a wireless charging pad (wireless charging).

All Android phones now support USB charging. The charging port in most Android phones has been shifting from micro USB to USB-C.

Both Galaxy S9 and S9+ have a USB-C port for charging and data transfer (e.g., back up Galaxy S9/S9+).

In your Galaxy S9 box, you can find the wall charger and the USB cable to charge Galaxy S9 battery.

Galaxy S9 and S9+ also support wireless charging. Samsung has added the wireless charging to Galaxy phones since Galaxy S6.

You can put Galaxy S9 or S9+ on a wireless charging pad to charge the phone.

Besides, you can also charge Galaxy S9 or S9+ when using Samsung DeX. In this situation, the adaptive wall charger is connected to a Samsung DeX Station or a Samsung DeX Pad.  Galaxy S9 or S9+ is connected to the USB-C connector of the DeX Station or DeX pad.

What is fast charging for Galaxy S9 and S9+?

A normal USB wall charger has a rated output current ranging from 500mA (0.5A/5V, 2.5W)  to 2000mA (2A/5V, 10W).

When using such USB wall chargers to charge Galaxy S9 and S9+, the charging voltage does not change. It is fixed at 5V. And Galaxy S9 and S9+ battery can take up to 2A current for this type of wall charger.

In addition to “normal” USB charging, Galaxy S9 and S9 also support fast charging when an adaptive wall charger (aka fast charger) is connected.

An adaptive wall charger can communicate with Galaxy S9 and S9+. Galaxy S9 and S9+ can then choose two charging modes:

In almost all regions, you still need a physic SIM card in Galaxy S9 0r S9+ to make calls or use mobile data connections.

Galaxy S9 SIM card guide will help you understand everything about using a SIM card in Galaxy S9 and S9+

Some questions related to using Galaxy SIM card are also answered.

What is the correct size of Galaxy S9 SIM card?

Galaxy S9 and Galaxy S9 and S9+ use nano-SIM cards, which is the smallest SIM card you can get from your phone company.

So, if you migrated to Galaxy S9 or S9+ from any of the following phones, you can use the existing SIM card for Galaxy S9 and S9+:

• Samsung Galaxy S6, S7 and S8 and all their variants (e.g., S8+, S7 edge, S6 edge and S6 edge+).
• Samsung Galaxy Note 5 and Note 8.
• Any of Samsung Galaxy A series: Galaxy A3, A5, A7, A8 and A9.
• Galaxy J3 2017 and later, Galaxy J5 2017 and later, Galaxy J7 and later.
• iPhone 5, 6, 7, 8 and X (and all variants).
• Moto X (all generations).
• Pixel and Pixel XL (all generations).
• LG G5, G6 (all variants), V10, V20 and V30.
• many others phones released after 2016

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:

1. Full-sizeSIM (1FF). Full-size SIM is  “giant” in size: 85.60 mm × 53.98 mm × 0.76 mm. No Android phones used it.
2. 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.
3. Micro-SIM

Dual aperture, which allows the system to choose the suitable Galaxy S9 camera aperture depending on lighting conditions,  is one of the significant improvements in Galaxy S9 (and S9+) camera compared to previous Galaxy phones.

However, in most camera modes, choosing Galaxy S9 camera aperture will be done automatically, and therefore you cannot manually select one of the two apertures.

The Pro mode is an exception, which allows you to manually choose Galaxy S9 camera aperture.

This Galaxy S9 camera guide explains dual aperture feature in Galaxy S9 and shows you how to manually choose Galaxy S9 camera aperture in the Pro mode.

What does dual aperture mean for Galaxy S9 camera aperture?

In photography, aperture, which controls how collimated the admitted rays are,  is one of the three legs of the exposure triangle.

Photographers use the combinations of aperture, ISO and shutter speed to get desired photos for various scenarios.

In most digital cameras or more expensive DSLRs, you usually have a certain level of control of the aperture.

But in smartphones, due to the compact size, the aperture of the camera lens is usually fixed.  Therefore, the camera app can control exposure through ISO and shutter speed.

Samsung introduced the dual aperture in the real camera od Galaxy S9 and S9+ so that the system can adjust the aperture based on lighting conditions.

Galaxy S9 and S9+ camera only supports two discrete apertures f/1.5 and f/2.4.  The system cannot set an aperture between these two values.

Typically, when ambient is very dark (in the night),  the system will set the aperture to f/1.5.  This allows more light to pass through the lens to get brighter photos.

When the ambient is very bright (e.g., under the sun), the aperture will be set at f/2.4. The photo will generally look more crispy than using f/1.5

How to use dual aperture to switch Galaxy S9 camera aperture manually?

Although dual aperture is a good feature for the rear camera, Samsung does not want you to mess up Galaxy S9 camera aperture. Therefore, aperture switching was programmed as an automatic Galaxy S9 camera feature.

In other words, it does not allow you to manually switch the Galaxy S9 camera aperture in most Galaxy S9 camera modes.

The only exception is the Pro mode, which allows you to control almost all aspects of the camera settings manually.

Please note, Pro mode is … Read the rest
