Owners of modern Samsung smartphones often face a lack of built-in memory, especially when it comes to installing “heavy” games. High-resolution graphics and large caches take up gigabytes, quickly filling up free space. The solution to the problem lies on the surface - using an external memory cards microSD, which allows you to expand the device's storage without losing data.
However, the process of transferring games to Android, and in particular to the shell One UI from Samsung, has its own technical nuances. Not all applications support direct transfer, and some require specific system configuration. In this article, we will look in detail at how to properly prepare the media, where to download files, and what restrictions the operating system imposes on working with external drives.
Preparing a memory card and smartphone settings
Before trying to move game files, you need to make sure that the external storage is correctly recognized by the system. Insert the microSD card into the slot of your device Samsung Galaxy and wait for the connection notification. The system will offer two options for use: as portable storage or as internal memory.
To store games and their cache, it is most often recommended to format the card as portable storage. This allows you to store media files and application data that are readable and writable. If you select internal memory mode, the card will be encrypted and tied to a specific phone, which will complicate its use on other devices, but may make it easier to install some applications.
⚠️ Attention: Formatting the memory card will completely delete all data that is already on it. Be sure to back up your photos and documents before starting setup in the smartphone menu.
You can check the status of the drive through the system menu. Go to Settings → Device maintenance → Memory. This displays the total capacity, free space and current operating mode of the SD card. Make sure that the system sees the full capacity of the media and does not display read errors.
Where to download the game: selecting a source and downloading
The main way to get games for Android is the official store Google Play Market. When loading heavy games, the system automatically detects the available space. If the internal memory is not enough, but the card is configured correctly, the Play Market may offer to install the application on external media, although this option does not always appear.
An alternative option is to download installation files APK and cache OBB from third-party resources. In this case, the user has full control over where the files will be saved. The browser or file manager saves downloads to internal memory by default, so you will have to move them manually.

- 📂 Third-party sources require manual unpacking of the cache to a folder

When downloading manually, it is important to respect the folder structure. The game cache must be located strictly along the path Android/obb/game_package_name. If you place the files in the root of the map or in another directory, the game simply will not start, giving an error loading resources.
Manual transfer of cache and game data
The most reliable method of installing a heavy game on a memory card is manual transfer of the cache. First, install the application itself (APK file) through the standard installer. After the first launch, the game will try to download additional files. If you interrupt this process or if space is low, the data will remain in the internal memory.
To move it, use the built-in file manager My files or a third-party explorer such as Total Commander or Solid Explorer. Find the game cache folder in the internal storage at Internal memory → Android → obb. Select the folder with the package name (for example, com.gameloft.android.ANMP.GloftA8HM) and execute the "Move" command.
Source path: /storage/emulated/0/Android/obb/com.game.package
Destination path: /storage/XXXX-XXXX/Android/obb/com.game.package
Paste the copied data into a similar directory on the memory card. The folder structure on the SD card must be identical to the internal one: card root → Android → obb → game_folder. After moving, restart the application. The game will check the integrity of the files and should start, loading resources from external media.
If the game after transferring the error “Cache not found”, check the access rights. On new versions of Android, access to the Android/obb folder on the memory card may be limited for some file managers.
Using the “Move to SD card” function in settings
Some versions of One UI and some Samsung models have a built-in app transfer feature available. This method is less reliable for games with a large cache, but is convenient for moving the application body itself. Go to Settings → Applications and select the desired game from the list.
Click on the item Memory. If the application developer has allowed the transfer, you will see an active button Change or Move to SD card. Click it and confirm the action. The system will automatically move the application's executable files, freeing up space in the internal storage.
| Data type | Can be transferred through settings | Requires manual transfer |
|---|---|---|
| APK file (application body) | Yes (if allowed) | No |
| Game cache (OBB) | Partial / No | Yes (in most cases) |
| Saving progress | No (depending on the cloud) | No (usually in the system) |
| Downloaded maps/levels | No | Yes |
It is worth noting that even after a successful transfer, some of the data will still remain in the internal memory. These are system files and settings that Android does not allow to be transferred to external drives for reasons of security and stability.
Features of working with the Android 11-14 file system
Starting with Android 11 and in current versions up to Android 14, Google has tightened the rules for accessing the file system (Scoped Storage). This made it much more difficult for applications and file managers to directly access folders on the memory card. Many games simply do not see the cache if it is on the SD card due to access restrictions.
In such cases, the standard transfer may not work. You may need to grant special permissions to the file manager. When you try to access a folder Android on the card, the system will ask for permission to access all files on the drive. You must click “Allow access to files” in the system dialog.
⚠️ Attention: On Samsung smartphones with the latest security updates, direct access to the folder
Android/obbon the SD card can be completely blocked for third-party applications. In this case, the game will only work if the cache is in the internal memory.Why do new games not want to work with an SD card?
Google developers and game manufacturers refuse to support external drives due to the low read/write speed of cheap memory cards, which causes freezes and long loading times levels.
If the game is critical and there is no space, you can try using a class memory card UHS-I U3 or V30. Such drives provide speeds comparable to internal eMMC or UFS memory, which reduces the likelihood of problems with texture loading.
Possible problems and solutions
Even if all instructions are followed, users may encounter errors. The most common problem is that the game displays the message “Not enough space” when starting, although there are several gigabytes free on the card. This is often due to the fact that the game tries to check the free space in the internal partition, ignoring the SD card.
Another common scenario is that the game starts, but crashes after a while. This may indicate damaged sectors of the memory card or file system incompatibility. Large cards (more than 128 GB) formatted in exFAT sometimes cause conflicts with older versions of games that expect the FAT32 file system.
- ❌ The “Application not installed” error often occurs when the APK file is damaged or there is not enough space in the internal partition for temporary files.
- ⚠️ Slow game performance indicates low card reading speed; try transferring the game back to the internal memory.
- 🔄 Resetting access rights in application settings can help if the system has “forgot” permission to read the SD card.
To diagnose the state of the card, use utilities like SD Insight or the built-in check in the storage settings. If the card is detected as fake or has bad sectors, the games recorded on it will be constantly damaged.

Frequently asked questions (FAQ)
Is it possible to transfer all games to a memory card on Samsung?
Unfortunately, no. The decision about the possibility of transfer is made by the application developer. Many modern online games and anti-cheat projects prohibit installation on external media. In addition, Android 11+ system restrictions block the cache on the SD card for a number of applications.
Why does the game require you to download the data again after transfer?
This happens if the folder structure is broken or the game does not have access rights to the new file location. Make sure that the folder with the cache is exactly on the path
Android/obb/package_nameon the memory card and that you have given permission to the file manager to access this data.Does the memory card affect the speed of the game?
Yes, it does. The internal memory of Samsung smartphones (UFS 2.1/3.1) is significantly faster than most microSD cards. Transferring the game to a slow card can lead to increased loading times for levels, slowdowns when loading textures, and long installation times for updates.
What to do if the “Transfer to SD card” button is inactive?
This means that the game developer has prohibited the transfer, or your version of Android does not support this function for this type of application. In this case, only manual transfer of the OBB folder through a file manager will help if the game supports launching the cache from external media.
