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

In Android Nougat update, Samsung introduced the blue light filter to tint the screen so that you can use the screen comfortably for a long time (e.g., for reading), or in a dimmed environment.

Many owners also hate the default white theme, which looks great in the showroom. For day-to-day use, many owners preferred a dark theme.

Of course, you can use third-party themes to customize the Galaxy S9 home screen and Samsung apps. But most of the dark themes in the Galaxy Apps (theme store) are poorly designed.

In Android Pie, Google introduced a dark theme. But it does not apply to Settings or to most Google apps.

Besides, Android Pie also introduced the night mode in developer options. But it is independent of the theme settings if dark them is used already. You may refer to this guide on how to use the dark theme and night mode in stock Android Pie.

In the Android Pie update for Galaxy S9 and S9+, Samsung added the night mode as an alternative to the default light theme.

How to use adapt sound on Galaxy S9 and S9+?

· 2 Comments

use adapt sound on Galaxy S9 and S9+Galaxy S9 adapt sound on Galaxy S9 and S9+ can significantly improve the sound quality of the phone.

The improvement is achieved through a personalized sound profile tailored to your ears.  Galaxy S9 adapt sound will conduct a hearing test for both of your ears to create that profile and compensate the frequencies you have problems with accordingly so that you can hear the “real” music and sound

This Galaxy  S9 guide explains in detail how the adapt sound on Galaxy S9 and S9+ works, and how to enable, customize and use the Galaxy S9 adapt sound to get the best audio quality on Galaxy S9 and S9+.

Please note, adapt sound on Galaxy S9 and S9+ is almost identical to that on Galaxy S10, S10+, Galaxy S8+, S8, Note 10, Note 10+, Note 9, and Note 8. So, this guide also applies to these and other Samsung phones.

What is adapt sound on Galaxy S9 and S9+? How does adapt sound on Samsung phones works?

Adapt sound on Galaxy S9 and S9+ is NOT new.  Samsung first introduced adapt sound in Galaxy S4 in 2013.

In the recent launches of Galaxy devices, Samsung even forgot to mention this audio feature, although Samsung tuned this feature in each generation of Galaxy devices.

But in my opinion, the adapt sound is one of the most useful Samsung features. And adapt sound on Galaxy S9 and S9+ is probably the most underused feature.

You should be very excited once you start to use the adapt sound on Galaxy S9 or other Samsung Galaxy phones: how excellent the music can be!  You probably will blame yourself: why I didn’t use it before!

In a nutshell, adapt sound on Galaxy S9 creates a personalized sound profile (effects) based on your ear.

Every ear is different. Even your two ears may differ significantly in hearing capabilities.  At different ages, our ears also have different listening capabilities at different frequencies.

So, the question is: did you hear the “real” music or sound?

Galaxy S9 conducts a hearing test for your ears to create your hearing profile.  Then use this profile to compensate the audio output so that you get the “real” music or sound.

For example, if your left ear has problems to hear sounds at around 15KHz, but your right ear does not have any issues for the same frequency range, then normally, you … Read the rest

Although the edge screen on Galaxy S9 and S9+ is not a new feature, many Galaxy S9 and S9+ owners still know little about using edge screen to improve their experiences with the phone.

This Galaxy S9 guide explains the details of Galaxy S9 edge screen, and how to use and customize edge screen on Galaxy S9 and S9+.

Since Galaxy S8, the edge screen features are unified on Galaxy S and Note devices. So this guide also applies to edge screen on Galaxy S8,  S8+, Galaxy Note 8 and Galaxy Note 9.

What is Galaxy S9 edge screen? The history of the edge screen on Samsung Phones

Galaxy S9 edge screen can be traced back to Galaxy Note Edge (Note 4 Edge), on which Samsung introduced a separate physical screen on the right edge of the standard screen in 2014.

But the reception of a dedicated edge screen was not as warm as expected. So, Samsung introduced the new “shared” edge screen in Galaxy S6 edge and S6 edge+. The edge screen was further polished in Galaxy S7 edge. Since Galaxy S8, Samsung has used curved screens on all flagship phones (Galaxy Note and Galaxy S series),

Galaxy S9 edge screen is a more or less matured feature in both Galaxy S9 and S9+.

There is no dedicated edge screen. Instead, you can trigger some useful features in the (curved) edge part of the main screen.

Edge screen on Galaxy S9 and S9+ is actually a productivity and software feature. It allows you to quickly access some features like opening apps, access tasks or contact your favourite friends.

Although the edge screen is conceptualized with the curved screen, only edge lighting utilizes the curved display. Other Galaxy S9 edge screen features (edge panels) do not rely on the curved edges of the infinity display and therefore can be easily implemented on a flat screen,

By default, edge screen on Galaxy S9 and S9+ was enabled when you got the phone.

In the right edge of the screen, as shown below, you can find edge screen handle.

How to use wireless printing on Galaxy S9 and S9+?

You can directly print documents and photos on Galaxy S9, S9+, S10, and S20 wirelessly to your printer

· 2 Comments

How to use wireless printing on Galaxy S9 and S9+?Wireless printing has been a native feature of Android for a long time. Galaxy S9 and S9+, of course, support it.

This means if you want to print any documents or photos saved on Galaxy S9 or S9+, you can directly print then from the phone, instead of copying them to a PC to print.

Most printer manufacturers have released their own apps for their printers. These apps usually also provide wireless printing features, in addition to other features.

This Galaxy S9 guide shows you how to set up and use wireless printing with the Android build-in printing feature, as well as with the vendor’s app.

You can use the same wireless printing feature on other phones including Galaxy S20, Galaxy S20+, Galaxy S2o Ultra, Galaxy S10, Galaxy S10+, Galaxy S10e, Galaxy Note 10, and Galaxy Note 10+.

What do you need to use wireless printing on Galaxy S9 and S9+?

To use wireless printing on Galaxy S9 or S9+, you need:

  1. A wireless printer.  If your printer can only use the USB connection to the PC, you have to use Google Cloud print, we will discuss it in other guides.
  2. A WiFi network which can be used by the printer and your phone (Galaxy S9 and S9+). Ethernet also works.
  3. A plugin for your printer. Almost all major printer vendors released the Android plugin in Google Play store. This guide will show you how to get it.

In this guide, we assume your Galaxy S9 or S9+ is connected to the same wireless router as the wireless printer. If not, you have to use Google cloud print, which is covered here (coming soon).

Steps of setting up wireless printing on Galaxy S9 and S9+

To print wirelessly from Galaxy S9 or S9+ to your printer, you need to install the print service for the brand of the printer you are using.

Wireless printing services (the plugin) on Android are provided by individual manufacturers. They are similar to the printer drivers on the PC. But on Android, typically, you only need to have one driver from (for) one vendor, instead of one for each printer. For example, if you have two different HP printers (both support wireless printing), you only need to install HP printer plugin once.

 Step 1: Check print services installed

How to use Galaxy S9 dual messenger to run two accounts of messenger apps simultaneously on Galaxy S9 and S9+?

You can simultaneously use two (or even three) accounts for WhatsApp, Facebook, WeChat, Facebook Messenger, Telegrams and other messenger apps with Galaxy S9 dual messenger feature

· 6 Comments

use Galaxy S9 dual messenger to run two accounts of messenger apps simultaneously on Galaxy S9 and S9+Galaxy S9 dual messenger makes it possible to have two accounts of the supported messenger apps (e.g., WhatsApp, Facebook Messenger, WeChat, Telegram, Viber…) and Facebook accounts in Galaxy S9 and S9+.

You can use these two messenger accounts simultaneously on Galaxy S9 or S9+.

Galaxy S9 dual messenger works on all Galaxy S9 and S9+ phones. It does NOT require the dual-SIM version of Galaxy S9 or S9+.

Dual messenger was first introduced in Galaxy S8. You can use the identical dual messenger feature on Galaxy S8, S8+, S9, S9+, Note 8 and Note 9.

This guide shows you how to use Galaxy S9 dual messenger to enable two accounts of messenger apps on Galaxy S9 and S9+. It also shows you how to disable individual messenger apps on Galaxy S9 dual messenger.

Why may you need to have two accounts of WhatsApp and other messenger apps in Galaxy S9 and S9+?

Many Galaxy S9 or S9+ owners may have different social profiles when they are in office, and when they are at home.

You may never want to mess up your personal WhatsApp or Facebook account with the account for work.

Some owners may want to show themselves differently in social media to buddies and to parents or teachers or supervisors.

Many Android apps support multiple profiles. For example, you can add multiple Google accounts to Galaxy S9. In Google+, you can quickly switch to different profiles.

But some apps limit one account on one device.

WhatsApp has been notoriously enforcing this policy since day 1. Facebook also requires you to sign out if you want to switch the account on the same phone.

But with more and more Galaxy S9 and S9+ owners use two SIM cards on the phone, there is a genuine need for running two messenger accounts concurrently on the phone.

Anyway, two or more WhatsApp (and other messenger apps) accounts can make your life easier by separating different aspects of your daily life.

How does Galaxy S9 dual messenger work?

Samsung initially tried to solve the work-life separation issue with the secure folder, which is a Knox-based container (like a small virtual machine, but not full Knox), in Galaxy S7 and S7 edge.

Secure folder works well in creating two spaces in one phone. But most owners do not use this feature because it is not so convenient. You … Read the rest

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.

How to use Galaxy S9 home screen landscape mode?

· 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
