  1. The first screen would be Always On display (if enabled). It will show certain information (like time, date, battery, music etc) on the black screen without any wallpaper or theme.

  2. Once you press the lock/unlock button on your phone, the display shown is the Lock screen on your phone.

  3. Finally, once your phone is unlocked, you will be taken to the home screen on your phone.

In this article, we will discuss on the features of the Samsung Lock screen and how you can use them for extra security and beautiful display along with all the required information so that you do not have to always unlock your phone to check certain information.

Samsung Lock Screen Security Settings

Screen Lock Type

You can set the lock of your screen by using the below options:

  1. Swipe: There is no security using this method, so not recommended

  2. Pattern: This is using a drawing pattern on your phone like a shape L, it is also not recommended as hackers can easily guess commonly used patterns.

  3. PIN: This is atleast 4 digits, is categorized as medium-high security. It can only contain numbers.

  4. Password: It is categorized as highly secure, must contain at least 4 characters including at least one letter.

  5. Biometrics: If your phone supports Face or Fingerprints or both recognition methods, this is highly recommended screen lock type on your phone.

Smart Lock

Samsung provides you smart lock options so that you don't have to unlock your device again and again when you are using it. It has implemented the below algorithms to recognize that you are using your phone.

  1. On-body detection: If you switch on this setting then your Samsung phone will stay unlocked once you unlock this device and it stays in motion after that. It will lock once you put it down in static position.

  2. Trusted Places: You can keep your device unlocked while at your phone location. You just need to add a trusted place on map and your phone remains unlocked there.

  3. Trusted devices: Samsung also gives you an option to keep your device unlocked while paired with your Bluetooth devices. You can select a particular device like your car Bluetooth or your Bluetooth headphones to keep it unlocked.

These are small enhancements in screen lock but are user friendly to avoid unnecessary locking on your phone.

Secure Lock Settings:

These settings provide you the options to be enabled to highly secure your phone from data theft and misuse.

  1. Auto lock when screen turns off: You can choose the time duration (for example: immediate, 5 seconds, 30 seconds, 1 minute etc) after which your phone gets locked.

  2. Lock instantly with power key: If this is enabled, your phone gets locked if you press the phone power key.

  3. Auto factory reset: This option is provided to you to enable if you want your phone to delete all your phone data once there have been 15 incorrect attempts to unlock your phone. It is designed to prevent any data privacy breach in case your phone is stolen. This is turned off by default.

  4. Lock network and security: This option will ensure that wi-fi and mobile data remains on even when your phone is locked. This is used by "Find my mobile" feature of your phone to locate and control your phone when your phone is lost.

Samsung Lock Screen Display Settings

Always On Display

The Always on display (AOD) is a feature provided by Samsung which allows you to customize your phone lock screen to display the selected information on your phone. You can choose from the below settings:

  • Tap to show for 10 seconds - If you choose this, the phone will display the information once you tap on your screen.

  • Show always - It will always show the information on your phone screen

  • Show as scheduled- You can schedule a time to set the Always on display, for example 9 am to 9 pm as you might not want your phone to consume the battery to show the information at night while you are sleeping.

As this does consume some of the phone battery (not much as it does not use all the phone pixels to display), we would recommend setting it for scheduled time.

Clock style: You can choose one of the various pre-defined clock styles to be displayed on your phone screen. It also gives you an option to change the default colour of the clock.

Show music information: This is by default selected and will show any music playing on any of the apps including Samsung Music, spotify and youtube so that you can change the tracks or pause from your lock screen using Always on Display.

Screen Orientation: Select between Portrait (vertical) and landscape (horizontal) mode for Always on display.

Auto brightness: Either enable this to let your phone choose the brightness based on the current light on your phone sensor or you can set the brightness yourself for Always on display.

Wallpaper Services

The wallpaper services on your phone provides the wallpapers to be set on your phone lock screen and the home screen. The lock screen provides you an option to choose from below wallpaper services

Dynamic Lock Screen:

This is one of the best wallpaper feature provided by Samsung which shows the different wallpaper each time you wake up your phone on the lock screen. The Samsung One UI 3.0 update on Android 11 has added new image categories for the dynamic lock screen and now you can choose up to 5 categories from which the images will be displayed on your phone. The image categories included in the dynamic lock screen are the below as of now:

  • Landscapes

  • Plants

  • Life

  • Dogs

  • Cats

  • Animals

  • Art

  • Food

  • Desserts

  • Special

You also get an option to switch off the download of dynamic wallpapers using mobile data.

If you select None for the dynamic wallpaper, you are presented with an option " Swipe left for Info page". Once you select this option, when you wake up your phone on lock screen (without any dynamic wallpaper) you can swipe left and are presented with the dynamic lock image categories and from there you can select the dynamic lock image category if you would like to set it.

Clock Style

The clock style feature gives you the options to select the clock style for the below

  • Always On Display: Clock styles for your Always on display option.

  • Lock Screen: Clock styles for your lock screen.

Roaming Clock

The roaming clock lets you save your home time zone (for example Chicago GMT-5) and when enabled will display the two time zones if you travel away from home location.

Let's say if you travel from Chicago to London, it will display both clocks on your lock screen.

You can also enable this for Always On Display.


You can add Widgets on the lock screen to display the most important information relevant for you. Below widgets are available to be selected for your lock screen:

  • Music

  • Today's schedule

  • Next Alaem

  • Weather

  • Bixby Routines

  • Digital Wellbeing

You can enabled these to be displayed on Always On Display as well.

Contact Information

This is the most essential information which you can set now on your phone so that there is always a probability of getting your lost phone back or someone else can contact your emergency contact in case you met with an unfortunate accident.

Always set your emergency contact in the contact information and it will be displayed on your lock screen. Anyone can dial in that number or contact on email ID without the need to unlock your phone.


You can switch on the notifications to be displayed on your lock screen. You can choose from either of the below options.

Icons Only: It will display just the icons without any further details. For example, missed calls, messages, mails etc.

Details: The details will show the content of the notifications as well. For example, who called you or the content of the message. You can further customize the details display on transparency and the text colour of the content.

You can display the notifications on the Always on display as well.


You can enable two shortcuts at the bottom of your lock screen: Left shortcut and Right shortcut.

These shortcuts can be accessed from the lock screen without any unlocking required on your phone. You can select the pre-installed or the additionally installed applications on your phone for the shortcuts. The default shortcuts are as the below:

Left shortcut: Phone

Right shortcut: Camera
