How to install games on an SD card on Xiaomi: Bypassing the restrictions of MIUI

Owners of budget and mid-budget smartphones Xiaomi, Redmi and POCO often face a lack of built-in storage. Heavy modern high-resolution graphics games can take up tens of gigabytes, quickly filling up the available space. Built-in memory is filled with system files, messenger cache and photos, leaving little room for entertainment.

Fortunately, many models support microSD card installation. However, standard installation of applications on an external media in the MIUI shell is often blocked or not working correctly. Android by default seeks to store all data on the internal drive for maximum download speed.

In this article, we will discuss proven ways to transfer game data, including using the external storage function and more advanced methods through the game. ADB. You will find out which games really work with SD-cards, and which is better to leave in the internal memory to avoid lags and departures.

Preparation of a memory card and smartphone

Before any manipulation of the file system begins, the external media must be properly prepared, and using a low-quality or too slow card will lead to games being loaded for eternity or constantly hanging, and speed classes of the map play a crucial role here.

For heavy installation 3D-Games are recommended to use standard cards UHS-I or UHS-II Class 10 or higher: The minimum recording speed must be at least 30 MB/s, which is indicated by the symbol V30.

Insert the card into the smartphone slot (often combined with the second one) SIM-If the card is new, Android will offer to format it. Choose the use case as Portable Storage if you want to easily transfer files to your PC, or Internal Storage for integration with the system.

⚠️ Warning: Formatting the card to Internal Storage will completely destroy all the data on it and bind the card to a particular device.

After formatting, make sure the system sees the full map volume. Go to Settings → About Phone → Storage. If the volume is displayed correctly, you can proceed to set up save paths.

💡

Use memory cards only from proven brands (Samsung, SanDisk, Kingston). Cheap counterparts with AliExpress often have real capacity 10 times less than claimed, which will lead to loss of game saves.

Standard Method through MIUI settings

The MIUI shell has a built-in feature that allows you to save new applications to an external medium by default, which is the easiest way to do it without root rights or a computer connection, but it doesn't work for all applications, because game developers can prohibit installation outside of internal memory.

To activate this feature, open the standard Security app (green shield icon). In the bottom menu, select the Memory or Cleanup section, and then look for the three-dot button or the settings gear in the top corner of the screen.

In the menu that opens, find the item "Memory" and switch the switch to "Install applications on the SD-Map is in active position. The system will warn that some applications may not work stable.

If the switch is missing or inactive, your MIUI version or a particular smartphone model does not support this feature at the system level, and then you will have to use alternative methods.

💡

The standard MIUI method only works for applications whose developer has explicitly authorized external drive installation, and for most heavy games, it is powerless.

Using ADB for Forced Transfer

If the standard settings don’t help, Android Debug Bridge comes to the rescue (ADB). This tool allows you to send commands directly to the operating system, without the limitations of the interface. USB-cable.

The first thing you need to do is activate the developer mode. Go to Settings → About the phone and quickly press 7 times on the MIUI version. You become a developer notification will appear.

Next, go to Settings → Advanced Settings → For developers. Find and enable the item “Debug by USB.” It is also recommended to include the item “Do not turn off the screen when charging” so that the smartphone does not fall asleep during data transfer.

Now connect your smartphone to your computer. Download the Platform Tools package from the official Android website. Open the command line in the tool folder and type in a command to check the connection:

adb devices

You'll see a request for debugging permission on your phone, click OK. If the console displays the serial number of the device, the connection is set. SD-map, enter command:

adb shell pm set-install-location 2

Here, 2 represents the priority of the external memory card, 0 returns automatic selection by the system, and 1 returns forced installation only in the internal memory.

⚠️ Attention: Team ADB It works globally on all applications that are installed. If you remove the memory card, the games installed through this method will stop running until it returns.

Manual transfer of cache and Obb files

Many modern games are divided into two components: the application itself (APK-file) and data files (cache). APK It weighs a little, and the bulk of the files are OBB, which can often be moved manually without loss of functionality.

After installing the game (even if it has been installed in the internal memory and has taken up space), find the Android/obb folder in the file manager. Inside there will be a folder with the name of the game, for example com.gameloft.android.

Copy this folder to a memory card in a similar way: /sdcard/Android/obb/ (where /sdcard can indicate the card itself, if selected by the primary storage, or use the path /storage/XXXX-XXXX/Android/obb). After transferring, you can try to delete the original from the internal memory.

Use the built-in MIUI Explorer or third-party solutions like Total Commander or FX File Explorer to manage files, which allow you to see hidden system folders and correctly display the directory structure.

This can lead to increased loading times and periodic twitching in open worlds.

Comparison of methods of game data storage

To better understand the pros and cons of each approach, let’s look at them in a comparative table, which will help you choose the best strategy for your smartphone model and type of games.

As you can see from the table, internal memory remains the leader in performance, but using a memory card is a compromise that allows you to make room for the system and other important applications.

For online shooters and dynamic racing, it is better to leave at least a minimum set of files in internal storage.Strategies and turn-based games are less demanding on the speed of data flow and can work comfortably from an external medium.

💡

Back up your OBB folder regularly, and if the game gets updated or files get damaged, you won’t have to re-download gigabytes of data over the mobile Internet.

Typical problems and their solution

Users may encounter errors during the setup process, and the most common is that the game is installed, but when it starts, it says, "No data files found," which means that the cache path is incorrect or access rights are limited by the MIUI security system.

Check permissions for the application. Go to Settings → Apps → All apps, select the game and make sure it is allowed access to Files and Media. Without that permission, the game simply won't see the files on the memory card.

Another problem is the sudden disappearance of the game icon after a reboot, which often happens when you have a game icon. SD-The card didn't have time to mount before the interface loaded. Try restarting the device again or checking the density of the card in the slot.

⚠️ Warning: Do not remove the memory card "hot" while the phone is on and running.This can damage the file system and lose all saves in games hosted on the media.

If the game starts to slow down more than before, try clearing its cache through the application settings. Sometimes the accumulated temporary debris on the slow memory card causes the interface lags.
