How to use different camera lens to zoom in and zoom out on Galaxy S20?

Galaxy S20 is all about the camera. The three primary camera lenses on the back of Galaxy S20 allows you to zoom in and zoom out quickly to capture any objects/scenes far or close.

For example, Galaxy S20 Ultra offers up to 100x super-resolution zoom and up to 10x hybrid zoom.

But many Galaxy S20 owners are a bit confused on choosing the correct camera lens and set the proper zoom levels.

This Galaxy S20 guide explains the differences among the three main (rear) cameras, the link between zoom and camera lenses, how to choose different camera lenses, and how to zoom in and zoom out properly.

In this guide, we mainly use the Galaxy S20 Ultra rear cameras as an example. When there are any differences, we will highlight whether the feature is for Galaxy S20 Ultra, or Galaxy S20 (and S20+). All camera software features on three Galaxy S20 models are identical, although Galaxy S20 Ultra has better hardware specs for the primary wide-angle camera and the telephoto camera.

What are the different camera lenses on Galaxy S20?

Besides the depth sensor camera on Galaxy 20+ and S20 Ultra, on all three models of Galaxy S20 phones, there are three camera lenses for different purposes:

Wide-angle camera.
Ultra-wide-angle camera.
Telephoto camera.

Galaxy S20 and Galaxy S20+ share the identical hardware of these three camera lenses.

Wide-angle camera

The 12MP (or 108MP on Galaxy S20 Ultra) wide-angle camera is the primary shooter. By default, you will take photos and record videos (except 8K videos) with this camera lens. Of course, you can choose other lenses if you want (read on).

On Galaxy S20 Ultra, you can choose to save the pictures as 12MP (at the aspect ratio of 4:3) after combining pixels, or as 108MP (which take s far more storage). Usually, you should save the photo as normal 12MP in indoor or low-light conditions. You may consider the108MP option when lighting is excellent (e.g., outdoor in sunny days).

Ultra-wide-angle camera

The 12MP ultra-wide-angle camera is identical on all three Galaxy S20 models.

With a field of view (FoV) of 120˚, this camera allows you to capture “more” in the frame. Compared to the 79˚ of FoV for the wide-angle camera, the area captured by the ultra-wide-angle camera nearly doubles. So, it functions as “zoom-out”.

You can lock the Galaxy S20 lock screen layout to avoid unintentional modifications of the home screen.

This Galaxy S20 guide explains when you need to lock the Galaxy S20 Home screen layout, how to do it, and the side effects of locking the layout of Galaxy S20 Home screen.

Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra share the same launched and the identical home screen settings. So this guide applies to all Galaxy S20 phones, although we use Galaxy S20 in the guide.

Besides, because locking the home screen layout is a feature of Samsung’s One UI launcher, you can find and use this feature on all other Galaxy phones with One UI, including, Galaxy S8, S9, S10, Note 8, Note 9, and Note 10, as well.

When do you need to lock the Galaxy S20 Home screen layout?

Thanks to the useless “curved” screen since Galaxy S6 edge, you may very easily touch the screen inadvertently and therefore move or remove some app icons or widgets on the Home screen.

Although Galaxy S20 makes the curved part of the screen less obvious, it is still a big distraction and a big waste (of usable screen space).

So, it is not uncommon that you may get surprised at the “new” Galaxy S20 Home screen: some app icons disappear, some app icons moved.

In the worst scenario, you may uninstall some apps inadvertently from the Galaxy S20 home screen when the phone is in your pocket or bag.

You can minimize such accidental modifications by locking the home screen layout.

Please note, when you boot Galaxy S20 into safe mode using hardware buttons, widgets may be removed even you lock the home screen layout, as explained here.

How to lock the Galaxy S20 Home screen layout?

By default, the layout of the Galaxy S20 Home screen is not locked.

For example, when you install new apps on Galaxy S20, the app icon (a shortcut to the app) will be added to the Galaxy S20 Home screen.

To lock the Galaxy S20 Home screen, you may follow the following steps.

The Ultimate Guide of Galaxy S20 Touchscreen Gestures

By simon Leave a Comment

You need to use the Galaxy S20 touchscreen gestures to use the phone effectively.

This Galaxy S20 guide explains the commonly used Galaxy S20 touchscreen gestures and shows you how to use them. The 8 Galaxy S20 touchscreen gestures covered are tapping, double-tapping, triple-tapping, long-tapping (tapping and holding), swiping, dragging, pinching and spreading.

Why do you need to know the Galaxy S20 touchscreen gestures?

We seldom attach a physical keyboard or mouse to Galaxy S20 (except using Samsung DeX). So, the touchscreen is the interface between the user and the Galaxy S20.

The phone takes commands from us through Galaxy S20 touchscreen gestures. We interact with the apps through those gestures, most of the time.

Since Android 10, Google removed the navigation buttons by default and recommended gestures for all navigations. Of course, Galaxy S20 still allows you to choose between using buttons or navigation gestures.

More and more Android apps also prefer gestures over buttons.

Anyway, it is hard to use the phone effectively without mastering Galaxy S20 touchscreen gestures.

What are the 8 Galaxy S20 touchscreen gestures?

You will need to use the following touchscreen gestures on Galaxy S20:

Tapping (single tap).
Double-tapping.
Triple tapping.
Long tapping (tap and hold).
Swiping.
Dragging.
Pinching.
Spreading

All of the 8 Galaxy S20 touchscreen gestures are universal on all Android phones. They work on almost all Android phones and therefore are not unique to Galaxy S20.

But the functions of each gesture may depend on individual apps.

Usage of Galaxy S20 touchscreen gestures

Now, let’s go through these 8 Galaxy S20 navigation gestures one by one.

Please note, we use “tap” in this guide. Other developers or writers may prefer “press”. They are identical for touchscreen gestures.

#1. Single tapping gesture (tapping)

The tapping gesture (aka single tapping), as shown in the animation below, requires you touch somewhere on the Galaxy S20 screen once, then move your finger away from the screen.

This gesture will be then registered as tapping, which is one of the most fundamental Galaxy S20 touchscreen gestures. It corresponds to “click” when using a mouse.

The outcome of the tapping gesture depends on what you tapped.

Here are some example of using tapping gesture on Galaxy S20:

Open an app by tapping the app icon.
Navigate to another page by tapping a menu item.
Toggle some Galaxy S20 features by tapping the quick setting buttons
