enable and use Galaxy S20 developer optionsYou can enable and use Galaxy S20 developer options to access some advanced or experimental features.

This Galaxy S20 guide explains when you need to enable developer options, how to enable and use the options, and a complete list of Galaxy S20 developer options. Examples of using Galaxy S20 developer options to add developer tiles to the quick settings panel, and to customise the default USB configurations are also included.

Please note, in this guide, Galaxy S20 refers to all three Galaxy S20 models: Galaxy S20, S20+, and S20 Ultra, because the developer options on these three phones are identical.

What are Galaxy S20 developer options?

Traditionally, Android hides with some special additional features for developers so that they can test their apps on any supported Android devices while normal users may never notice such features.

Some beta, experimental, and even legacy features were also hidden in Andriod devices. Google has to make sure that such features are visible only to users who are aware of such features,

Developer options in Android devices is a collection of these features. Some Android vendors may add or remove a few entries on their devices.

Galaxy S20 developer options are very similar to those in stock Android 10. Only a few new entries were added by Samsung.

Update: After you update Galaxy S20 to Android 11, you may notice there are minor changes in the developer options. For example, you cannot find the option to customise the app icon shapes.

When do you need to enable and access Galaxy S20 developer options

If you are an Android developer, surely, you can use the developer options to test apps on Galaxy S20, instead of the virtual machines of Pixel or Nexus devices.

Samsung is the largest Android vendor. So, it is necessary to test apps on the latest Galaxy phones.

Besides developers, many Android enthusiasts may also try some experimental or beta features of Android 10 on Galaxy S20.

For typical Galaxy S20 owners, you may still occasionally need to enable and use the developer options to access certain features. For example:

  • You want to force all apps to be resizable so that you can use it in both pop-up view and split-screen view.
  • You want to force all apps (except system apps and pre-installed apps) to use the micro SD card. As explained in this guide, many app developers

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.

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.

The role of Galaxy S20 Home screen

After unblocking Galaxy S20 lock screen, the first screen you will use is the Home screen.

Of course, if you unlock Galaxy S20 with face recognition, you have the option to stay on the unlocked lock screen or directly navigate to Home screen, as explained in this guide.

Galaxy S20 Home screen is the centre of the phone. Most of the functions and apps are accessed from the Home screen.

How to use and customize Galaxy S20 navigation buttons?

use and customize Galaxy S20 navigation buttonsGalaxy S20 navigation buttons allow you to navigate across, into and back out from the different pages of an app, Galaxy S20 Home screen, Apps screen and lock screen.

Although Android 10 introduced the full-screen navigation gestures,  Galaxy S20, by default, uses the traditional three navigation buttons for you to interact with the phone.

This Galaxy S20 guide explains the three navigation systems on Galaxy S20 (navigation buttons, Android 10 full-screen navigation gesture,  and Samsung navigation gestures) and the functions and usage of Galaxy S20 navigation buttons (Recents, Back, and Home). It also shows you how to customize the layout (order) of Galaxy S20 navigation buttons

The navigation buttons are identical on Galaxy S20, S20+, and S20 Ultra, although we used Galaxy S20 in the guide.

What are the three navigation systems on Galaxy S20?

When you interact with Galaxy S20, you can use one of the following 3 navigation systems to navigate through different apps, or within an app, or through pages of Home screen, Apps screen, and lock screen:

  1. Galaxy S20 navigation buttons (the default).
  2. Android 10 full-screen navigation gestures.
  3. Samsung’s full-screen navigation gestures.

The full-screen navigation gestures remove all buttons (including the Home button). This guide explains these gestures and illustrates how to use them on Galaxy S20.

On the contrary, Galaxy S20 navigation buttons keep and use the traditional 3 navigation buttons.

Although navigation buttons look old-fashioned, they can be more efficient for many Galaxy S20 owners.  This is the main reason why Samsung keeps Galaxy S20 navigation buttons as the default option when you set up Galaxy S20.

Please note, since Galaxy S8, Samsung ditched the hardware capacitive navigation buttons and adopted the software-based navigation buttons.

In other words, Galaxy S20 navigation buttons are NOT physical buttons (see Galaxy S20 layout). They are generated by the Android system when needed. And therefore, it is possible to disable/hide them and switch to full-screen navigation gestures without using any of these buttons.

What are the Galaxy S20 navigation buttons?

As shown in the screenshot below, there are three navigation buttons on the Galaxy S20 navigation bar:

  1. Home button
  2. Back button
  3. Recents button (aka, Overview button)

Please note, the screenshot shown below is the default navigation button layout on Galaxy S20 (and all Samsung phones), which is opposite to the layout on other Android phones.

How to unlock Galaxy S20 to Home screen directly (without swiping on Galaxy S20 lock screen) with face recognition?

How to unlock Galaxy S20 to Home screen directly (without swiping on Galaxy S20 lock screen) with face recognition?By default, after you unlock Galaxy S20 with face recognition, you are not directed to the Home screen. You have to swipe on the lock screen to reach the Galaxy S20 Home screen.

Many Galaxy S20 owners want to reach the Home screen without swiping on Galaxy S20  lock screen when using face recognition to unlock Galaxy S20.

As Galaxy S20 uses the inferior and inconvenient in-display fingerprint sensor,  most  Galaxy S20 owners find the face recognition (face unlock) is the most convenient way to unlock Galaxy S20 quickly.

This Galaxy S20 guide shows you how to unlock Galaxy S20 to Home screen directly without swiping on Galaxy S20 lock screen when using face recognition on Galaxy S20.

The face recognition on Galaxy S20, S20+, and S20 Ultra works identically. So, this guide applies to all of these 3 Galaxy S20 models although only “S20” was used in the text.

Besides, the default face recognition (face unlock) settings are similar on all Samsung Galaxy phones with Android 10. This guide also applies to most other Samsung Galaxy phones with Android 10 update including Galaxy S10, Galaxy Note 10, Galaxy S9, Galaxy Note 9, Galaxy S8, and Galaxy Note 8.

Why I still stay on the lock screen after unlocking Galaxy S20 with face recognition?

When face recognition is enabled, you may inadvertently unlock Galaxy S20.

For example, you may pick up the phone just to check the time.  But the face recognition is activated and may unlock Galaxy S20 automatically whenever the screen is wakened up.

To mitigate this side effect of face recognition unlocking method on Galaxy S20, Samsung, by default, lets you stay on the lock screen if the phone is unlocked by face recognition. If you actually want to unlock the phone, you need to swipe on the Galaxy S20 lock screen to go to the Home screen.

As shown in the screenshot below, after unlocking Galaxy S20 with face recognition, you are still on the lock screen page. The open lock icon on the top of the lock screen and “Swipe to open” text on the bottom tells you that the phone is unlocked.  You can open the Home screen by swiping on the Galaxy S20 lock screen.

Of course, you can change this setting (read on) so that you can reach the Home screen without swiping on Galaxy S20 lock screen.

The Ultimate Guide of Galaxy S20 Touchscreen Gestures

Galaxy S20 Touchscreen GesturesYou 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:

  1. Tapping (single tap).
  2. Double-tapping.
  3. Triple tapping.
  4. Long tapping (tap and hold).
  5. Swiping.
  6. Dragging.
  7. Pinching.
  8. 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

How to hide Samsung Daily (Bixby Home) on Galaxy S20?

disable or hide Samsung Daily (Bixby Home) on Galaxy S20You will encounter the unwelcomed Samsung Daily in the Galaxy S20 Home screen when you unbox your Galaxy S20.

Luckily, you can easily disable or hide Samsung Daily (Bixby Home) on Galaxy S20 Home screen.

This Galaxy S20 guide explains what Samsung Daily is, why you should disable/hide it, and how to hide it on Galaxy S20.

Please note, Samsung preinstalled the Samsung Daily as a system-essential app. So, you cannot disable it or remove it from the phone. You can only disable or hide Samsung Daily from Galaxy S20 home screen.

Samsung Daily is a software (app) feature.  It works on all three Galaxy S20 models (Galaxy S20, S20+, and S20 Ultra) identically.

What is Samsung Daily on Galaxy S20?

Samsung Daily was introduced in Samsung’s Android 10 update for Galaxy S10 last year.

Although the name is now, Samsung Daily is simply a rebranded Bixby Home, which more than 90% of Galaxy owners turned off (or tried to turn off) on old generations of Galaxy Phones.

By default, Samsung Daily occupies the leftmost panel of Galaxy S20 Home screen. It mimics the Google (Google Now) page on the stock Android.

It supposes to deliver relevant and customized info for you by crawling your emails, calendar, messages, reading history, location, and other private info. It is Samsung’s version of Google Now page.

Because Samsung preinstalled the Samsung Daily as an essential app (part of the launcher), you cannot uninstall or disable it on Galaxy S20.

The good news, like in Galaxy S8, S9, and S10, you can hide Samsung Daily on Galaxy S20 very easily. So, we did not list it as one of the worst Galaxy S20 features.

Why you may want to hide Samsung Daily on Galaxy S20?

I am not a fan of Bixby Home or Samsung Daily.  We always recommend Galaxy phone owners to disable it.

You may also consider to hide or disable Samsung Daily on Galaxy S20 home screen for the following three reasons.

Reason 1: Bixby is not as smart as Google Assistant.

Google Assistant is unarguably superior to Bixby. Period.

So, the info delivered from Bixby Home (Samsung Daily) generally is less useful than asking Google Assistant.

Reason 2: Data collection and third-party providers

Some processing jobs (e.g., analyze your habits/preferences), are done in the cloud. This means Samsung need to … Read the rest
