Smartphone owners Samsung often face a situation when the device’s built-in storage suddenly becomes full. This happens unnoticed: you install your favorite games, social networks or graphic editors, and the system begins to warn you about a critically low level of free memory. At such moments, the only logical solution is to use the memory card slot, which is provided in most models of the Galaxy line.
Transferring data is not just copying files, but a complex procedure that affects the structure of the Android file system. Modern versions of the One UI shell provide the user with flexible tools for managing the contents of the drive. However, there are a number of nuances that even experienced users are not aware of, which leads to errors or incomplete freeing up space.
We will analyze in detail all available moving methods software, from standard system settings to advanced methods using a computer. You will learn which applications can be moved and which will remain “glued” to the internal storage forever, and how to avoid data loss during the migration process.
Preparing the device and memory card
Before starting any manipulations, you need to make sure that your smartphone ready to work with external media. Not every memory card is suitable for storing active applications. For correct operation of the system, a drive with a high write speed corresponding to class UHS-I or higher is required. Slow cards can cause the interface to freeze and apps to crash.
Insert the microSD card into the appropriate slot on your Samsung device. After that, go to settings and format the drive. It is important to understand that formatting will delete all existing data on the card, so save important photos and documents on your computer or in the cloud in advance.
⚠️ Attention: When formatting a memory card for use with applications, the system may encrypt it. This means that the card will only work on that specific phone and cannot be read on other devices or computers without a special reset.
Check whether the system recognizes the new media. To do this, go to menu Settings → Device Maintenance → Memory. Here you will see the total amount of internal memory and the amount of available space on the SD card. If the card is displayed correctly, you can start setting up.
Make sure that the USB debugging option is enabled on the device if you plan to use third-party software to force the transfer. This feature is located in the developer menu, which is hidden by default. To activate it, you need to quickly click on the build number seven times in the section About phone → Software information.
☑️ Preparing for transfer
Standard transfer method through the settings
The easiest and safest way to change the location of applications is to use the built-in tools of the Android operating system. This method works normally for most pre-installed apps downloaded from the store that are not blocked by the developer for moving.
Open the application settings section. The path may vary slightly depending on the version of One UI, but it usually looks like Settings → Applications. You will see a complete list of installed software. You need to find the application that takes up a lot of space and which you want to move.
Click on the name of the desired app to open its details page. The amount of memory used, version and access rights are displayed here. Find the button Memory or section Storage. This is where the switch responsible for the physical location of the app files is located.
If the button Change is active, the system will allow you to select the target media. Click on it and in the window that appears, select Memory card. The system will automatically begin the file migration process. The execution time depends on the size of the application and the speed of your microSD card.
If the "Change" button is inactive or missing, then the application developer has prohibited its installation on external media. In this case, transfer is not possible using standard methods.
After the process is completed, the application icon may momentarily disappear from the desktop and reappear. This is normal system behavior and indicates that the service is restarting after changing the path to the executable files. Now the main part of the app data resides on external media.
| Application type | Possibility of transfer | Where the data remains |
|---|---|---|
| System applications | Impossible | Internal memory |
| Messengers (WhatsApp, Telegram) | Partially | Cache and media on the card |
| Games with cache | Possibly | Main file on map |
| Banking applications | Locked | Internal memory |
Transferring media files and application cache
Often the problem of lack of space is not associated with the application files themselves, but with their cache and user data. Messengers, such as WhatsApp or Vibercan take up gigabytes of space, storing the chat history and received images in the internal memory by default.
To solve this problem, it is not necessary to transfer the application itself. It is enough to change the settings for storing media files within a specific service. Go to the messenger settings, find the section Data and storage and specify the path to save downloaded files to the memory card.
You can also manually move already accumulated files. Use the built-in file manager My Files (My files). Go to section Internal memory → Android → media. Folders with data for most installed apps are stored here. Select the desired folders and select the function Move.
Insert the memory card as the target direction. This method is especially effective for offline navigation maps, podcasts, and downloaded videos from streaming services. These files often weigh more than the application itself, and moving them frees up a significant amount of space.
⚠️ Attention: When manually moving folders from the Android directory, make sure that the application is closed at this time. Otherwise, an access conflict may occur, and the app will no longer see its data, requiring re-authorization or configuration.
Some applications allow you to choose where to save downloads in their own settings. For example, browsers or email clients often have a Download path. Change it from internal storage to an SD card so that all new files are automatically saved there.
Using Adoptable Storage mode
In older versions of Android and some custom firmware, there was a feature that allowed you to combine the internal memory and microSD card into a single space. On modern smartphones Samsung this feature is often hidden or disabled by the manufacturer for stability reasons.
Nevertheless, it is worth checking for this option. When you connect the card for the first time, the system may offer to use it as internal memory. If you agree, the system will format the card and encrypt it, making it an integral part of the system. In this mode, new applications will be installed on the card by default.
This method has its advantages and disadvantages. On the one hand, you forget about manual transfer. On the other hand, the speed of the smartphone may decrease if the memory card is slower than the built-in flash drive. In addition, it will be impossible to remove the card without losing data and resetting the phone.
Why did Samsung disable this function?
The manufacturer believes that memory cards are less reliable than built-in eMMC or UFS memory. A sudden failure of the card can lead to the loss of important system data and inoperability of applications.
If the standard menu does not offer this option, you can activate it only through console commands from the computer by connecting the phone in debugging mode. However, this requires high qualifications and carries the risk of turning the device into a “brick” if errors occur.
For most users, it is safer to use the card as portable storage and transfer applications selectively, as described in the previous sections. This maintains a balance between performance and available space.
Force transfer via computer (ADB)
For advanced users who want to move applications that the system considers "fixed", there is a tool ADB (Android Debug Bridge). This method allows you to bypass the restrictions set by application developers and forcefully change the installation location.
You will need a computer with ADB drivers installed and a USB cable connected. After enabling USB debugging on your phone, enter the command in your computer terminal to get a list of all packages: adb shell pm list packages. Find the package name of the desired application.
adb shell pm move-package com.example.app sdcardThis command initiates the transfer of the specified package to the external drive. Please note that not all application components can be moved. Some system libraries will still remain in the internal memory, but the bulk of the data will be transferred.
⚠️ Attention: Using ADB commands requires caution. An error in the command syntax or the transfer of a critical system component can lead to unstable operation of the operating system or cyclic reboot of the device.
After executing the command, check the result through the phone settings. If the application has moved, you will see a corresponding change in the memory section. If the command returns an error, it means that this application is strictly tied to the system partition and cannot be transferred.
The ADB method gives maximum control over the file system, but requires a PC and technical knowledge. Use it only if standard methods do not help.
Possible problems and their solutions
During operation, situations may arise when transferred applications stop working correctly. Most often this is due to the memory card losing contact or changing its mounting path. The system simply cannot find the files needed to start.
If the application crashes immediately after launch, try restarting your smartphone. Sometimes the system takes time to index files on new media. Also check that the memory card is securely inserted into the slot.
Another common problem is that widgets for migrated applications disappear from the desktop. This happens because widgets are often hard-wired to internal storage. You will have to add them again by holding your finger on an empty area of the screen and selecting the desired item from the menu.
- 📉 Slowdown: If the phone starts to slow down after the transfer, the memory card may not be fast enough to run heavy applications. Try returning the app to internal memory.
- 🔒 Access error: Applications may request permission to access files again after moving. Go to the access rights settings and confirm them.
- 📂 Data loss: In rare cases, if there is a power failure during the transfer, the data may be damaged. Always have a backup copy of important settings.
You should also be aware that application updates may reset the installation path back to internal memory. After a major update via Google Play, you should check the location of the app and, if necessary, move it again.
Frequently asked questions
Is it possible to transfer all applications at once with one button?
Unfortunately, there is no such function in the standard One UI shell. Each application must be transferred individually through the settings menu. There are third-party utilities, but their effectiveness is limited by system access rights.
Will the application be deleted if you remove the memory card?
The application itself will not be deleted, but it will stop running. The icon will remain on the screen, but when you click it, you will receive an error stating that the application is not installed or the data is not available. After returning the card to its place, all functions will be restored.
Does the transfer affect the speed of games?
Yes, it can influence. If the read speed of your memory card is slower than the built-in drive, the loading time of levels and textures in games will increase. For heavy 3D games, it is recommended to leave them in the internal memory.
Why are some applications not portable at all?
Application developers can prohibit installation on external media in the app manifest. This is often done to protect licensed content, ensure the security of banking transactions, or guarantee stable operation of the service.
