Has the icon of your favorite messenger disappeared from the main screen? Or did you accidentally delete the system application via Settings? On smartphones Samsung Galaxy with a shell One UI applications can disappear for various reasons: from a banal user error to failures in the launcher. Fortunately, in 90% of cases, you can return them back without resetting the phone to factory settings.

In this article - 5 working ways returning applications to the screen, including restoring hidden icons, uninstalling system utilities and even solving problems with “gray” icons after updates Android. We will analyze the nuances for different versions One UI (from 4.0 to 6.1) and explain why some applications can automatically hide after installing security updates (this applies to models Galaxy S22/S23 and newer).

Before proceeding to the instructions, check two things: 1) Make sure that the application is not located in the "Unused" folder (it is created Samsung to save space on the screen). 2) Try to find the app through a phone search - swipe down on the main screen and enter the name in the line.

1. Searching for an application in the “All applications” menu

The easiest way is to check if the application is hidden in the general list of apps. On Samsung Galaxy s One UI there are two types of menus:

  • 📱 Home screen —only pinned applications are displayed here.
  • 📂 All applications —a complete list of installed software (available by swiping up from Dock panel).

To return the icon to the home screen:

  1. Swipe up from the bottom of the screen to open the menu All applications.
  2. Find the application you need (use search at the top if the list long).
  3. Long-press the icon and drag it to the main screen or to the dock panel.

If the application is not in this menu, proceed to the next method. Exception: some system utilities (for example, AR Zone or Samsung Free) can be disabled - they need to be enabled via Settings.

2. Recovering from the Unused or Archive folder

Samsung automatically hides rarely used applications in a special folder. This applies to both user apps and some system apps (for example, Samsung Notes or Galaxy Store). To get them back:

  1. Open the menu All applications (swipe up from the dock panel).
  2. Scroll the list to the end - there should be a folder "Unused" (or "Archive" on new models).
  3. Click on folder, find the desired application and press its icon.
  4. Drag it to the main screen or to the dock panel.

On Galaxy S23 Ultra and other flagships of 2023–2026, the folder may be called "Hidden applications". If it is not there, check the launcher settings:

  • 🔧 Press and hold an empty space on the main screen → Settings → Hidden applications.
  • 🔍 Enable displaying hidden apps.

3. Cancel the removal of system applications through Settings

If the application was uninstalled (and not just hidden), it can be returned through the menu Settings. This works for system utilities (for example, Samsung Health, Bixby, Game Launcher), but not for user apps from Google Play.

Instructions:

  1. Open Settings → Applications.
  2. Tap on the three dots in the upper right corner and select Show system applications.
  3. Find the desired application in the list (use search).
  4. If there is a button next to the name "Restore" or "Enable" - click it.

On One UI 5.0 and later, some applications (for example, Samsung Pay) may require updates through the Galaxy Store after recovery. If there is no “Restore” button, the application has been completely uninstalled and will have to be reinstalled manually.

What to do if there is no "Restore" button?

This means that the application was deleted as a custom one (for example, through ADB or a third-party uninstaller). In this case:

1. Check for the presence of the APK in the backup copy (if you made a backup via Smart Switch).

2. Download the original APK from a trusted source (for example, [APKMirror](https://www.apkmirror.com/)).

3. Install manually, allowing installation from unknown sources in Settings → Security.

⚠️ Be careful: installing modified APKs may disrupt the system!

4. Resetting the launcher settings (without data loss)

If applications disappear massively or “gray” icons are displayed in their place, the problem may be a launcher failure One UI Home. In this case, resetting its settings will help:

  1. Open Settings → Applications.
  2. Find One UI Home (or Samsung Experience Home on older models).
  3. Tap Storage → Storage management → Reset settings.
  4. Confirm the action and reboot the phone.

After the reset:

  • 🔄 All icons will return to their places (but pinned widgets will have to be configured again).
  • 📁 The “Unused” and “Archive” folders will become visible.
  • ⚙️ Theme and wallpaper settings will be saved.
⚠️ Attention: On some firmware (for example, Galaxy A52 s One UI 4.1) resetting the launcher may cause the weather and clock widgets to temporarily disappear. They will be restored after a reboot.
Problem Cause Solution
Icons have become gray Cache failure One UI Home Resetting launcher settings
The application disappeared after updating Automatically hiding rarely used apps Checking the "Unused" folder
There is no "Restore" button in Settings The application was deleted as a user one Manual APK installation
Applications disappear after reboot Conflict with battery optimizer Disable launcher optimization

5. Reinstalling the application via Galaxy Store or Google Play

If the application was removed manually (for example, via Settings → Applications → Uninstall), it will have to be installed again. For system utilities Samsung use Galaxy Store:

  1. Open Galaxy Store (icon with a blue logo Samsung).
  2. Tap on the icon profile → My applications.
  3. Go to the tab Deleted.
  4. Find the desired application and click "Install".

For custom apps (for example, WhatsApp, Instagram) use Google Play:

  • 🔍 Open Play Market → enter the name in the search.
  • 📥 If the application is already was installed earlier, instead of the button “Install” there will be "Restore".
⚠️ Attention: On Galaxy S24 and other models with One UI 6.1 some system applications (for example, Samsung Wallet) may require authorization through Samsung Account when reinstalling. Make sure you are signed in to your account before restoring.
💡

If the application does not appear in the list of deleted ones in the Galaxy Store, try clearing the store cache: Settings → Applications → Galaxy Store → Storage → Clear cache. After that, restart your phone and check again.

6. Checking the battery optimizer and permissions

Sometimes applications do not “disappear” physically, but stop being displayed due to restrictions imposed by battery optimizer or resolutions. This is typical for Galaxy M and Galaxy Aseries with aggressive optimization of power consumption.

How to check:

  1. Open Settings → Device maintenance → Battery.
  2. Tap Restrictions for background applications.
  3. Make sure that the application you need is not in the list "Sleeping" or "Deep sleep".
  4. If yes, uncheck the box and restart the phone.

Also check permissions:

  • 🔓 Settings → Applications → [Application name] → Permissions.
  • 🚫 Make sure there are no restrictions on displaying notifications or icons.

A One UI 6.0 function has been added that can hide icons of rarely used applications. To disable it: "Automatic optimization", which can hide icons for rarely used applications. To disable it:

Settings → Device maintenance → Three dots (⋮) → Settings → Automatic optimization (turn off)
💡

If the application disappears after each system update, the problem is a version conflict. Try to roll back the update via Settings → Software update → Three dots (⋮) → Rollback (not available on all models).

Frequently asked questions (FAQ)

❓ Why after updating to One UI 6.0 application icons disappear?

The One UI 6.0 Samsung added a function "Adaptive Home Screen"that automatically hides rarely used applications in the “Unused” folder. To disable this:

  1. Long-press an empty space on the home screen → Settings.
  2. Disable the option "Adaptive home screen".

Also check whether the "Light version" launcher is turned on (it hides some of the icons to save resources).

❓ How to return standard Samsung applications (for example, Calendar or Contacts), if they deleted?

Standard applications Samsung (Contact, Calendar, Messages) cannot be completely removed - they can only be disable. To return:

  1. Open Settings → Applications.
  2. Tap on three dots → Show system applications.
  3. Find the desired application (for example, Samsung Contacts) and click "Enable".

If there is no "Enable" button, the application has been replaced by a version from Google (for example, Google Contacts). In this case, it can only be reinstalled via Smart Switch from a backup.

❓ Is it possible to return a deleted application without the Internet?

Yes, if:

  • 📥 There was an application hidden, and not deleted (see the section about the "Unused" folder).
  • 🔄 You have backup via Smart Switch (recover data from it).
  • 📦 The application was disabledand not uninstalled (enable it in Settings).

If the application was completely removed, to reinstall you will need the Internet (via Galaxy Store or Google Play).

❓ Why do widgets disappear after resetting the launcher?

Resetting One UI Home returns only application icons to standard positions. Widgets (weather, clock, notes) are deleted, since they are tied to specific screen settings. To restore them:

  1. Press an empty space on the main screen → Widgets.
  2. Find the widget you need (for example, Weather or Calendar).
  3. Drag it to the screen and configure again.

On Galaxy Z Fold/Flip widgets can “fly off” after unfolding the screen - this is a feature One UI for foldable devices.

❓ How to prevent automatic hiding of applications in the future?

To Samsung not hide the icons yourself:

  1. Disable "Adaptive home screen" (see FAQ above).
  2. Add important applications to dock panel (they are never hidden).
  3. Regularly open rarely used apps (at least once every 2 weeks) so that the system does not consider them “unused.”
  4. Disable "Automatic optimization" in the battery settings.

On One UI 5.0+ you can also pin folders with applications on the main screen - they will not be automatically cleaned.
