How to use 5 different shooting methods for Galaxy S20 camera?

By simon Leave a Comment Last Modified: December 6, 2020 · Published on: December 6, 2020

In addition to the shutter button, you can use other shooting methods, including volume key, voice commands, floating shutter button, and palm, to take photos or shoot videos on Galaxy S20.

This Galaxy S20 guide explains the 5 different shooting methods for Galaxy S20 and shows you how and when to use them.

As Samsung updates the Camera app with the Android OS (and One UI), you can find the Samsung Camera app on Galaxy phones with identical Android (and One UI) version is almost identical. Therefore, this guide applies to most Samsung Galaxy phones with Android 10 (and One UI 2.5), for example, Galaxy S10, Galaxy Note 10, and Galaxy Note 20.

Why do you need to consider shooting methods other than the shutter button for Galaxy S20 camera?

By default, most Galaxy S20 owners use the shutter button (aka capture button) in the preview screen to take photos or record videos.

But occasionally, you may find it is not convenient to use the shutter button when taking selfies, especially when you want to include more people or the background and therefore you have to stretch your arm out.

For owners who get used to a point-and-shoot camera or DSLRs, a physical shutter button is always preferred. Unfortunately, all Android phone manufacturers are trying to minimize the number of physical buttons (and ports).

The good news is Samsung has maintained alternative shooting methods in their Galaxy phones. Therefore you can use volume keys, voice control, floating button, and palm to take photos and record videos.

What are the 5 different shooting methods for Galaxy S20 camera?

In the Galaxy S20 Camera app, you can use at least the following 5 shooting methods:

Use the shutter button (default).
Use the volume key.
Use voice control.
Use a floating shutter button.
Show your palm (for selfies only).

We will explore them later (read on). By default, voice control and floating button are disabled on Galaxy S20.

When and how to use different shooting methods for Galaxy S20 camera?

As mentioned, two of the additional methods (voice control and floating shutter button) are not enabled by default; therefore, you need to enable them before you can use them.

Enable/disable different shooting methods for Galaxy S20 camera

You can manage, enable, and disable individual shooting methods in Galaxy S20 camera settings.

It actually shows the volume slider. By default, it adjusts the volume for the ringtone. Of course, you can change this behaviour (read on)

On most of other Android 9 and 10 phones, the volume keys always adjust the media volume. Google removed the volume slider on the Android Pie (Android 9) in stock Android. But Samsung has kept the similar volume slider on all Galaxy phones for many years (since Android 4.0).

So, this guide only applies to Samsung phones, not other Android phones.

You may also tap the icon on the left side to mute that sound quickly. For example, you can tap the ringtone icon to immediately mute ringtone. If you tap it again, the volume will be reset … Read the rest

How to easily take a screenshot on Galaxy S20 without using any third-party apps?

By simon Leave a Comment Last Modified: November 21, 2020 · Published on: May 11, 2020

Galaxy S20 provides the native capability for you to take a screenshot on Galaxy S20 easily without installing any third-party apps.

The built-in Galaxy S20 screenshot toolbar can also further help you take screenshots for elongated pages automatically, edit, and share the captured screenshots efficiently.

This Galaxy S20 guide shows you the 4 easy ways to take a screenshot on Galaxy S20 without using any third-party apps and explains how to use the screenshot toolbar to take a screenshot for scrollable pages, edit, share, and add tags to the captured screenshot.

This guide applies to Galaxy S20, Galaxy S20+, and S20 Ultra, although we use Galaxy S20 in the text.

4 easy ways to take a screenshot on Galaxy S20

Taking screenshots on Galaxy S20 is not only easy but also fun. There are a few different ways to take a screenshot on Galaxy S20 without using any third-party apps.

In this guide, I will show you the four easiest ways to take screenshots on Galaxy S20, S20+, and S20 Ultra.

Hardware key method (Side key + volume down key)

In all Android devices, the built-in method of taking a screenshot is holding the power key and volume down key simultaneously.

On Galaxy S20, the Side key replaces the traditional power key.

So, the corresponding method of taking a screenshot on Galaxy S20 is to hold the Side key and volume down key simultaneously, as illustrated below (you may check Galaxy S20 layout on the location of the side key and volume key).

The only requirement is to hold the two keys simultaneously. It needs some practice if you are new to this method:

If you get the volume adjustment bar (aka volume slider), it means you press the Side key too late.
If you get the power button option (power-off menu), then it means you press the volume down button too late.

Anyway, you may try to hold the Side key slightly earlier than the volume down key.

Palm Swipe to capture

The funniest way to take a screenshot on Galaxy S20 is to swipe your palm over the screen, as illustrated below.

This method is a bit tricky. Your palm should “slightly” touch the screen.

If the palm is too far from the screen, then swipe will not be registered. If it touches the screen too hard, then the swipe may be registered as a touchscreen gesture… Read the rest
