Transfer applications to the SD card on Xiaomi Redmi 5: the complete guide

Owners of the popular budget smartphone Xiaomi Redmi 5 often face a lack of built-in storage, especially in the version of 16 or 32 gigabytes. the MIUI system installed on the device by default aggressively manages memory resources, leaving the user only a small part of the declared volume after installing all updates and system services, which leads to constant notifications about the lack of space and the inability to install new programs from Google Play.

Fortunately, the Redmi 5 is equipped with a microSD card slot that theoretically allows you to expand the available space (APK-files) on an external drive is not possible - this option is simply not available in the settings menu. To solve this problem, you need to use deeper methods of system configuration, including the use of debugging on the system. USB and command line.

In this guide, we will detail safe and effective ways to bypass the limitations of the shell. MIUI. You will learn how to transform SD-It is important to understand that the interference with system files requires care, but with the right approach allows you to significantly extend the comfortable use of the device.

Analysis of MIUI memory limitations on Redmi 5

The Android operating system that underpins the MIUI shell initially supports Adoptable Storage, which allows internal and external memory to be combined into a single space. However, smartphone makers including Xiaomi often turn this feature off at the software level, to ensure device stability, as the speed of reading and writing budget memory cards can be lower than that of the built-in eMMC module.

On Xiaomi Redmi 5, the situation is complicated by the fact that the standard settings menu offers only the use of the card as a portable storage for photos, videos and documents. When you try to install a heavy application, the system automatically saves it in the internal partition, ignoring the free space on the device. SD-This creates an artificial scarcity of space that cannot be eliminated by conventional methods.

⚠️ Warning: Forced application portability can lead to a decrease in overall smartphone performance if a low-speed memory card is used.

There are several levels of access to memory management: the first level is standard settings, the second is the use of hidden developer menus, and the third is deep system intervention through ADB (Android Debug Bridge), which is the most effective method for the Redmi 5 model, allowing you to activate hidden features of the file system.

SD card preparation and speed class requirements

Before you start modifying the system, you need to make sure the quality of the drive used. To work in the mode of emulation of internal memory, the card must have a high speed of random read and write. The use of cheap Class 4 or Class 6 cards is strongly discouraged, as this will lead to long downloads of applications and possible interface freezes.

The optimal choice for Xiaomi Redmi 5 will be UHS-I cards with a speed class marking U1 or U3. It is desirable that the manufacturer provides a guarantee and declares a read speed of at least 80-90 MB / s. Popular brands like SanDisk, Samsung or Kingston usually provide stable work in conjunction with mobile processors Snapdragon.

Before starting the procedure, all important data from the card must be copied to the computer or to the cloud storage. The process of reconfiguring the file system involves completely formatting the drive, as a result of which all current information will be irretrievably lost. Also make sure that the battery of the smartphone is at least 50-60%.

• 📀 Check the card for physical contact damage.
• 📀 Make sure that the card is determined by the smartphone in normal mode.
• 📀 Back up all files from the card to the PC.
• 📀 Charge the Redmi 5 battery to at least 60%.

Once prepared, you can insert the card into the smartphone slot, and the system will suggest formatting it as a portable storage device, so long as you agree to this, to check the performance, and only after a successful test, you can proceed to the next stage of setting up.

Activation of the developer mode and debugging via USB

To interact with Android system files, you need to get advanced permissions through the developer menu. On the MIUI shell, this process has its own peculiarities. First, you need to activate the menu item itself, hidden from the average user. To do this, go to Settings → About the phone and find the line version of MIUI.

You have to quickly click on this line 7-10 times in a row until you have a pop-up notification that you have become a developer, and then a new Developer option will appear in the main settings menu, in the Additional section, and that's where the key switches that we need for our task are.

Inside the developer menu, find the debugging option USB And you can activate it. You can alert the system to the potential risks, you can confirm the action. USB-debugging (Security settings) if available in your firmware version, allowing application installation via USB and debugging through Wi-Fi.

Importantly, when you connect your smartphone to your computer, you'll see a request for debugging permission on the screen. You'll need to tick Always allow from that computer and press OK. Without this step, the computer won't be able to send the necessary commands to the device.

Using ADB for Forced Transfer

The most reliable way to get Xiaomi Redmi 5 to transfer applications to the Internet SD-map - use of tools ADB This method does not require the acquisition of superuser rights (Root), which preserves the guarantee and integrity of the system partitions. You will need to download the minimum package Platform Tools from the official Android developer website.

After unpacking the archive on your computer, open the command line in the tool folder. Connect your smartphone with a cable and enter the connection verification command:

adb devices

If a device with a serial number appears on the list, the connection is successfully established, and then you need to enter a command that changes the global variable of the system that allows you to install applications on external drives:

adb shell pm setInstallLocation 2

Here, the number 2 indicates the priority of the external memory card, the value 0 returns the standard settings (auto-selection system), and 1 sets the priority of internal memory. Once the command is executed, the changes take effect immediately, without the need to restart.

⚠️ Note: The setInstallLocation command is a hint for the system, but not all applications support installation on an external drive. Many modern programs (banks, instant messengers) ignore this parameter for security reasons.

Alternative method: Formatting as internal storage

There is a more radical method that transforms SD-This process is called Adoptable Storage. On Redmi 5, it's not available through the standard menu, but it can be activated through the system partition. ADB Be careful: this method encrypts the card, and after that it will not be read on any other device without formatting.

First, you need to know your card ID. Type a command into the console:

adb shell sm list-disks

The system will give you a response in disk:179.64 (numbers may differ). Write down this identifier. Next is the formatting command, which will create the necessary partitions:

adb shell sm partition disk:XXX private 100

Where disk:XXX is your ID. 100 means that 100% of the card volume will be given to applications, then the system can suggest a reboot, and when you return to the storage settings, the card will be displayed as part of the internal memory, and the applications will automatically move to it.

This method is considered more stable for long-term use, as it is native to Android, but it imposes strict requirements on the quality of the map.If the card fails, data recovery will be extremely difficult, and some system functions may stop working correctly.

Comparison of methods and possible problems

The choice between simply changing installation priority and fully formatting depends on your goals: the first method is safer and more reversible, the second one is more effective, but more risky. The table below compares the characteristics of both approaches for the Xiaomi Redmi 5.

One of the common problems is when the MIUI firmware update resets, in which case the ADB procedure will have to be repeated, and users may experience some applications stop updating or crash when they start, which is a signal that a particular application is incompatible with running from an external drive.

💡

Use a file manager with root access (if any) or built-in storage analyzer to regularly check which folders take up the most space and manually clean the messenger cache.

In some cases, manually porting already installed applications helps. Go to Settings → Apps → All apps, select the desired program. If the Move button is active (not grey), it can be pressed. However, on newer versions of Android, this button is often blocked for system applications.
