The Samsung Galaxy S8’s Hardware Buttons

The Samsung Galaxy S8’s Hardware Buttons

The Galaxy S8’s hardware is different from many other mobile phones in design: it has far fewer hardware buttons (the phone’s physical buttons). They rely more on on-screen software buttons.
Samsung has reduced the number of hardware buttons on the Galaxy S8. There are only three: the power button, the volume button, and the Bixby button. Before you get started with your phone, orient yourself to make sure you’re looking at the correct side of the phone. The gestures to the left or right of the phone assume a vertical orientation (meaning you’re not holding the phone sideways) and that you’re looking at the phone’s screen.
power button
The power button is on the right side of the phone, facing up when you hold it in a portrait orientation.
In addition to turning on the phone, pressing the power button puts the device to sleep if you hold it down for a moment while the phone is on. Sleep mode locks the screen and suspends most running applications.
The phone automatically goes to sleep after about 30 seconds of inactivity to save power, but you may want to do this manually when you put your phone away. The Super AMOLED display on your Samsung Galaxy S8 is great, but it also uses a lot of power.
Do not confuse sleep mode with shutdown. Since the screen is the biggest user of power on your phone, making the screen blank saves battery life. The phone is still alert for any incoming calls; When someone calls, the screen lights up automatically.
Volume button(s)
Technically, there are two types of volume buttons: one to increase the volume and one to decrease it.
The volume buttons control the volume of all audio sources on the phone, including
1. Ring the phone when a call comes in (ringtone)
2. Notifications that only appear when you’re not talking on the phone, such as an optional ping that lets you know you’ve received a text or email
3. The handset when you are talking on the phone
4. The volume level of the digital music and video player (media)

Context-aware audio controls; They can tell which size you are changing. For example, if you are listening to music, adjusting the volume raises or lowers the volume of the music, but leaves the ringer and the handset unchanged.
The volume buttons are complementary to software settings that you can make within apps. For example, you can open the music player software and raise the volume on the appropriate screen. After that, you can use the hardware buttons to lower the volume, and you will see the volume setting on the screen go down.
Another option is to go to the settings screen and set the volume levels for each scenario. Here’s how to do it:
1. From the home screen, press the Volume button.
You can press it either up or down. Doing so brings up the screen shown here.
If you press the volume up or down, the ringtone becomes louder or softer. Stop this mod for now and move on to the next step.

2. From this screen, click on the down arrow in the upper-right corner.
3. From the displayed screen, adjust the volume to the desired setting.
You can adjust the volume of any setting by placing your finger on the point in the slider image. The point will get bigger; You can move it to the left to lower this volume setting or to the right to raise it.

Bixby button
The Bixby button was previously shown on the phone. It’s below the volume buttons. Bixby is an app from Samsung that is an Intelligent Agent (IA). It’s like Siri on the iPhone. It’s great, but it still needs some work. The plan is that you can launch this app by pressing the Bixby button twice. For now, it will take you to the Bixby screen.
