How to make applications saved to a memory card on Samsung

Smartphone owners Samsung often face a lack of built-in storage, especially when it comes to the basic models of the series Galaxy A or old flagships. The built-in memory quickly fills up with system files, messenger caches and heavy games, which slows down the device. A logical solution seems to be to use a card microSD to offload the main storage, but modern versions Android have significantly limited this ability for security and performance reasons.

Previously, users could easily move any application to external storage with one click of a button in the settings. Today, the corporation Google and device manufacturers, including Samsung Electronicsrecommend storing apps in internal memory to ensure system stability. However, there are working methods and workarounds that allow you to partially or completely transfer application data to a memory card, which we will discuss in detail in this article.

Before taking active steps, you need to clearly understand the difference between transferring the application body itself and saving the media files created by these applications. Complete migration of executable app code to external media is not always possible and depends on the version of the operating system and the policy of the developer of the specific software. At the same time, setting up saving photos, videos and documents on SD card is available on almost any device and is the most effective way to free up space.

Limitations of modern versions of Android on Samsung devices

Starting with version Android 6.0 and especially in current shells One UIbased on Android 11, 12, 13 and 14the function of transferring applications has been practically abolished. This is due to the fact that the reading and writing speed of even the fastest memory cards (class UHS-I or UHS-II) is significantly inferior to the speed of standard built-in drives UFS 3.1 or UFS 4.0.

When an application is running from external media, the system may experience delays when loading resources, which leads to slowdown of the interface and unstable operation of apps. That is why in the standard smartphone settings menu Samsung the "Move to SD card" button is often missing or inactive for most pre-installed and popular third-party applications.

⚠️ Attention: An attempt to forcefully transfer system applications or critical Google services to a memory card may lead to a cyclic reboot of the device or complete inoperability smartphone.

However, some developers leave the option of choosing the installation location in the code of their application. If such an option is provided, you will be able to see the corresponding button in the app management menu. Otherwise, you will have to resort to more complex configuration methods or be content with transferring only user data.

Basic setup of the camera and multimedia for saving to SD

The easiest and safest way to relieve internal memory is to set up automatic saving of photos and videos directly to the memory card. This does not require obtaining root access or connecting to a computer and is available in the standard camera interface Samsung.

To activate this feature, open the Camera application and click on the gear icon in the upper left corner of the screen. In the settings menu that opens, find the item “Storage location” or “Save to SD card”. After switching the toggle switch, all new pictures and videos will be automatically sent to external media, bypassing the internal memory.

In a similar way, you can configure saving files in other applications. For example, in the browser Samsung Internet or Chrome you need to go to the download settings and specify the path to the memory card. In instant messengers like Telegram or WhatsApp this option may be in the "Data and Storage" section, where you can find a folder for saving received media files.

• 📸 Open the camera settings and activate the option to save to external media to instantly unload memory.
• 📁 Check the settings of the voice recorder and video editors, as they often write files to internal storage by default.
• 🎵 In music players and podcast applications, specify the memory card as the main location for caching offline content.

Already existing photos and videos will remain in the internal memory, and you will have to move them manually through the file manager. To do this, go to the "My Files" application, select the desired folders (for example, DCIM/Camera) and use the "Move" function, selecting your SD card as the destination.

Standard method of transferring applications through settings

Despite the limitations, it is worth checking whether a particular application supports transfer using standard system tools. This method is the most secure and does not require the installation of additional software. It only works for those apps whose developers have explicitly allowed this feature.

To check the availability of the function, go to the menu Settings → Applications. Select the app you are interested in from the list. If the developer has provided the possibility of migration, the "Storage" button will be active in the application menu. By clicking on it, you will see the “Change” or “Move to SD card” button.

If the button is inactive (gray) or completely absent, it means that the application is firmly tied to the system partition. In this case, standard methods will not solve the problem. Typically, banking applications, system services Samsung and popular social networks that require high speed access to data have such protection.

Application type	Probability of transfer	Recommendation
Games (cache data)	High	Transfer cache through game settings
Social networks	Low	Clear cache manually
Office packages	Average	Saving documents to the card
System utilities	Absent	Do not touch, leave inside

If the transfer is successful, part of the application data is moved to the card, but some space still remains in the internal memory to ensure fast loading. This is normal system behavior Android, aimed at balancing space saving and performance.

Using developer mode to force a transfer

There is a hidden an option in the menu for developers that allows you to force installation of applications on external media, even for apps that do not officially support this. This method does not guarantee stable operation of all apps, but it often works for simple utilities and games.

First, you need to activate developer mode. Go to Settings → Phone information → Software information. Tap "Build Number" 7 times in a row until a message appears indicating that Developer Mode is enabled. After this, a new section “Developer Options” will appear in the main settings menu at the very bottom of the list.

In this section, find the item “Allow saving to external drives” (or “Force allow apps on external”). Activate this switch. After enabling this option, you must restart your smartphone. Now, when you go to the settings of installed applications, the transfer button may become active for more apps.

⚠️ Attention: Enabling this function may cause application widgets to stop working, and the apps themselves will take longer to launch than usual. Use with caution.

It is worth noting that after disabling this setting or removing the memory card, applications installed on it will no longer launch until the media is returned to its place. Also, some banking applications may block their operation when they detect changed system parameters.

What to do if the item does not appear?

If you do not find the item “Allow saving to external drives,” the manufacturer may have completely cut this function out of the firmware for your model. In this case, only methods using ADB will help.

Advanced method: Using ADB and the command line

For users who are ready for more complex manipulations, there is a method of using the toolkit ADB (Android Debug Bridge). This method allows you to bypass many shell software restrictions One UI and force changes to application installation attributes. To work, you will need a computer with OS Windows, macOS or Linux.

First you need to download and install the drivers Samsung USB Driver and package Platform Tools from the official website of Android developers. Connect your smartphone to your computer via the original cable and enable USB debugging in the developer menu on your phone. Open a command prompt on your computer in the ADB tools folder.

To migrate a specific application, use the command specifying its batch name. First, find out the package name using the command adb shell pm list packages. Then run the command to migrate:

adb shell pm move-package com.example.appname external

Replace com.example.appname with the actual package name of your application. If the operation is successful, the system will inform you that the transfer is complete. However, you should be prepared for the fact that some applications may refuse to launch or work with errors, since they are not designed to work with slow external storage.

• 💻 Make sure that the latest drivers are installed on your computer to correctly detect the device in the system.
• 🔌 Use a high-quality USB cable, as an unstable connection can interrupt the transfer process data.
• 🛑 Do not disconnect the phone from the computer until the command in the terminal is completed.

This method gives the greatest control over the file system, but requires technical literacy. An error in entering the command may result in the application becoming unavailable until the reverse operation or reinstallation is performed.

Formatting a memory card as internal storage

In some versions of Android and firmware Samsung The "Adoptable Storage" function is available, which allows you to format the memory card as part of the internal storage. In this case, the system encrypts the card and combines its capacity with the main memory, allowing you to install applications directly.

To try to activate this function, insert a memory card, go to Settings → Device maintenance → Memory. Click on the name of your SD card and select "Storage Settings". If there is a "Format as internal storage" option, select it. Please note that all data on the card will be permanently deleted.

After formatting, the system will consider the card an integral part of the phone. You won't be able to simply take it out and insert it into another phone or card reader without losing access to the data. In addition, the speed of the entire smartphone will be limited by the speed of the memory card.

⚠️ Attention: Samsung has officially disabled this function in most of its modern devices due to the low quality of memory cards on the market, which quickly fail when intensively recording system files.

If this item is not in the menu, it is almost impossible to activate it programmatically without obtaining root access. In this case, it is better to use the card only as portable storage for media files, so as not to risk the stability of the operating system.

Frequently asked questions (FAQ)

Why does it work slower after transferring an application to the card?

The speed of reading random blocks of data for microSD memory cards is much lower than that of the built-in UFS flash memory chips. The application takes longer to load resources, which causes delays in the interface and long loading levels in games.

Is it possible to transfer WhatsApp completely to a memory card?

The WhatsApp application itself cannot be completely transferred due to Android security restrictions. However, you can transfer the database with correspondence and media files. To do this, in the WhatsApp settings, select "Chats → Backup of chats" and configure saving to Google Drive or manually move the folder Android/media/com.whatsapp to the card.

What will happen to applications if I remove the memory card?

Applications installed on the card will no longer run, and their icons may disappear from the desktop or become inactive. The system will report an error when attempting to open. After returning the card to its place, functionality is usually restored automatically.

How to learn how much space an application actually takes up?

Go to Settings → Applications, select the desired app and click "Storage". There will be two values ​​indicated: the size of the application itself and the size of user data (cache). The sum of these values ​​shows the actual volume occupied by the app.

Is it safe to use the ADB command to transfer system applications?

No, it is extremely dangerous. Migrating system applications (for example, Phone, Contacts, System UI) may make it impossible to boot the operating system (bootloop). Transfer only third-party apps that you downloaded from the store.
