Understand and Use Galaxy S21 Lock Screen

You have to use the Galaxy S21 lock screen to secure your Galaxy S21 and control access to your phone and data.

This Galaxy S21 how-to guide explains the role of the Galaxy S21 lock screen, pages, layout and the meaning of each item on the Galaxy S21 lock screen, and how to use gestures on the lock screen.

The lock screen is identical on all Galaxy S21 phones (Galaxy S21, S21+, and S21 Ultra). So this guide applies to all Galaxy S21 phones.

The role of the Galaxy S21 lock screen

The lock screen is an essential part of a smartphone.  It is part of the security system of the phone.

You can think Galaxy S21 lock screen as the only entrance for your Galaxy S21. It is an analogy of the main door of your home.

Therefore, you need to secure the lock screen on Galaxy S21 so that only you can “unlock” it. You should set up a screen lock (PIN, password, or pattern) to lock down the lock screen.

But at the same time, you may want to check some info (e.g., check the time or notifications) or control music playing without unlocking Galaxy S21. So, you do not want to have a blank lock screen.

Sometimes, you may want to allow you or others to make emergency calls without unlocking the phone.

So, the Galaxy S21 lock screen has dual roles:

1. To stop unauthorized access to your data and apps (with a screen lock).
2. To offer some convenience features without unlocking the phone.

Anyway, it is more than just “locking” your Galaxy S21. In fact, the Galaxy S21 lock screen comprises 3 screens/pages: main lock screen, dynamic lock screen, and unlock screen (keypad/keyboard/pattern screen).

Also, as explained here, the lock screen itself is just a “door”.  You need to add the “lock” for the door. It is recommended to use a PIN or a password for it.

Please note, you ana always turn off the Galaxy S21 screen by pressing the Side key once.

Layout and meaning of all items on the Galaxy S21 lock screen

By default, you may see the following 11 items on the Galaxy S21 lock screen, as shown in the screenshot below.:

1. Mobile network (carrier) name.
2. Face recognition status icon.
3. Lock screen status icon.
4. Galaxy S21 status icons in the status bar
5. Clock/widgets area
6. Contact info.
7. Notification.
8. Fingerprint reader illustration.
9. Charging status.
10. Phone app shortcut
11. Camera app shortcut.

We now go through them one by one.

Mobile network (carrier name)

By default, on the top left, the name of the carrier is displayed.

This is very useful when your Galaxy S21 is roaming. You can quickly check whether you are on the desired network because your carrier may have a preferred roaming partner.

You may follow this Galaxy S21 SIM card guide if you have any questions on using SIM cards or eSIM on Galaxy S21.

Face recognition status icon

When you wake up the lock screen, the face recognition (if enabled) will try to recognize your face. You will see the ring flashes around the front-facing camera.

Please note, face recognition is activated for about 5 seconds to save battery. If no face is recognized within 5 seconds, you may have to use other unlock methods, e.g., fingerprint or PIN/password/pattern.

Lock screen status icon

By default, when you unlock Galaxy S21 with face recognition or smart lock,  Galaxy S21 will still keep you on the “unlocked” lock screen.

The purpose of this default behaviour is to avoid accidental unlock and, therefore, inadvertent touches.

Once the Galaxy S21 is unlocked, the lock icon will turn into an unlocked lock icon, as shown below.

In this status, you can swipe to access the Galaxy S21 Home screen.

For face recognition, you can choose to skip this screen and go directly to the Home screen, as explained in this guide (which applies to both Galaxy S20 and Galaxy S21).

Galaxy S21 status icons in the status bar

On the top right of the Galaxy S21 lock screen, you will see an array of status icons.

You may check this guide on the meaning of these Galaxy S21 status icons.

Clock/widgets area

By default, there is a digital clock on the Galaxy S21 lock screen so that you can check the time without unlocking the phone.

But on Galaxy S21, the area occupied by the clock actually is a widget area with multiple widgets collapsed under the clock.

So, you can tap (single tap is enough) the clock to expand to see all lock screen widgets. Please refer to this guide on how to use lock screen widgets on Galaxy S20 and Galaxy S21.

The clock style can be customized in Settings — Lock screen —Clock style.

Contact info

If you want, you can leave your contact info on the lock screen.  In case you lose your phone, someone holding the phone can easily reach you.

Some Galaxy S21 owners may put emergency contact info or medical condition here in case of emergency.

Of course, you should NEVER put sensitive info here.  Such info is not protected. Anyone holding the phone can see it.

You can customize the contact info on the Galaxy S21 lock screen in Settings —  Lock screen — Contact info.

Notification

By default, the Galaxy S21 lock screen displays the notification icons in this area, not the status bar (top of the screen). On the lock screen, only status icons appear on the status bar.

You can choose (Settings — Lock screen — Notifications):

• To disable notifications on the lock screen. There will be no notifications on the lock screen at all.
• To show notification icons only (default).  You will only see notification icons.
• To show notification details. Detailed notification messages will be shown on the lock screen, just like in the notification panel.

Besides, you can choose to hide or show contents for sensitive notifications.

Fingerprint reader illustration

As one of the worst Galaxy S21 features, the in-display fingerprint reader is invisible to our eyes, and therefore the Galaxy S21 lock screen needs to highlight the location so that we can use it.

You need to put your finger roughly in the illustrated area to use your fingerprint to unlock Galaxy S21.

Charging status

If you are charging the Galaxy S21 battery, the charging status will be shown on the lock screen.

The charging status appears regardless of the charging method (USB cable charging or wireless charging).

Phone app shortcut

By default, on the bottom left of the Galaxy S21 lock screen, there is a Phone icon. This is the shortcut to the Phone app.

The phone app can be used in two ways:

• Make emergency calls without unlocking Galaxy S21.
• Make normal calls when Galaxy S21 is unlocked by face recognition (or smart lock), and you are still on the lock screen. So, it is more efficient than navigation to the Home screen.

When Galaxy S21 is locked, only emergency calls can be made through the phone app.

You can customize this slot with other apps. But remember, most apps cannot be used until the phone is unlocked.

Camera app shortcut

On the bottom right of the Galaxy S21 lock screen, you can find a camera icon.

You can use Galaxy S21 Camera app without unlocking the phone.  Actually, you can also use Galaxy S21 camera quick launch without unlocking the phone.

But if you use the camera app when Galaxy S21 is still locked, you can only check and manage photos taken in the current session.  You cannot check other photos.

Also, you may change some of the Galaxy S21 camera settings without unlocking the phone. But some settings, for example, enabling or disabling location tags, can only be changed after you unlock the phone.

Similar to the Phone app shortcut, you can also replace the camera app with other apps in Settings —  Lock screen — Shortcuts.

The two other pages of Galaxy S21 lock screen

As mentioned, the Galaxy S21 lock screen actually has 3 different pages. In addition to the main lock screen page discussed above, you can swipe left or right to access the other two.

If you swipe from right to left on the lock screen, you will access the Dynamic Lock screen page, as shown in the screenshot below.

The Dynamic Lock screen offers fresh content (curated by Samsung) as your lock screen wallpapers. You can choose up to 5 categories of images, and these pictures will be updated automatically roughly every 2 weeks.

You may check this guide on how to use the Dynamic lock screen on Galaxy S21, S20, Note 20, and Note 10.

If you are using the navigation buttons on Galaxy S21, there is a Back button on the Dynamic Lock screen page, as shown in the screenshot below. If you use NavStar to customize the navigation bar and navigation buttons, including the Show and hide the navigation bar, you will see the customizations on the lock screen as well.

Of course, the button disappears if you are using navigation gestures on Galaxy S21.

If you swipe from the other 3 directions (downwards, upwards, or from left to right) on the Galaxy S21 lock screen, you will then access the keypad/keyboard/pattern dots page (unlock page) for you to unlock the phone with PIN/password/pattern, as shown in the screenshot above.  You can choose to hide the password or PIN when typing them on the lock screen, as explained in this guide.

Of course, once you access this page, face recognition will automatically start again at the same time.  You can also use fingerprint on this page.

You can also make emergency calls on this page, as shown above.

How to use gestures on the Galaxy S21 lock screen?

You can use the following touchscreen gestures on the Galaxy S21 lock screen:

As mentioned earlier, to use the app shortcuts, you need to swipe (not tap) the app icon to the centre of the screen.
