Transfer applications to the memory card Xiaomi Redmi Note 7: Deep setup

Owners of the popular Xiaomi Redmi Note 7 model often face a lack of built-in storage, especially in the base 32 or 64 gigabyte versions. Internal memory is quickly filled with system files, messenger cache and heavy games, which leads to a slowdown in the interface and the inability to install new programs. Android operating system, on which the MIUI shell is based, provides the theoretical possibility of using an external drive as a continuation of the system partition, but manufacturers often hide this feature.

Standard methods of transfer through settings usually allow you to move only media files, leaving the applications themselves “chained” to the internal module. To fully solve the problem requires deeper intervention in the structure of files and the use of debugging tools. In this article, we will discuss in detail the technical details of the operation of the ext4 file system and FAT32, and also consider safe ways to activate hidden smartphone functions without losing warranty.

Technical limitations of the MIUI file system

The problem of the inability to directly install programs on SD-The map is embedded in Google's security policy and Xiaomi's engineers, and since Android 6.0, Adoptable Storage has been introduced, allowing for the integration of internal and external memory into a single pool. MIUI, block this function at the kernel level of the system to prevent problems with the performance and stability of the device.

External microSD drives often have lower write and read speeds compared to built-in eMMC or UFS flash memory. If the system starts to actively use a slow card for system processes or application cache, this will lead to noticeable interface friezes and quick battery discharge. That is why the standard Settings → Memory menu does not have a “Use as internal storage” button.

⚠️ Warning: Forced memory integration using a low-quality memory card can lead to irreversible data loss and reduced overall responsiveness of the Redmi Note 7 system.

However, there are workarounds that force the system to consider the external drive suitable for application installation, which require the use of a computer, USB cable and special debugging software, and it is important to understand that any manipulation of system partitions carries minimal risks, so you need to create a full backup of important data before starting the procedure.

Preparation of a memory card and choice of speed class

The first and critical step is to choose the right storage device: not every microSD card is suitable for emulating internal memory; applications require high speeds of random reading and writing of small files, not just linear speeds when copying large video files; the minimum recommended standard is Class 10 or UHS-I.

The best choice is cards labeled A1 or A2 (Application Performance Class), which ensures that the drive is tested for the ability to run and maintain mobile applications. Using cheap cards without these labels will cause games and programs to load longer after transfer than before transfer, and in the worst case, constantly fly out.

Before formatting, you need to extract all the important data from the card to the computer, since the preparation process for use as internal memory involves the complete destruction of information. The file system will be changed and the partition structure will be rewritten. It is recommended to use cards with a volume of 32 to 128 gigabytes, as support for large volumes on older versions of MIUI can be unstable.

• 🚀 Choose cards with markings A1 or A2 for maximum application performance.
• 💾 The optimal volume for the Redmi Note 7 is 64-128GB to avoid addressing issues.
• 🛡️ Buy drives only from official dealers to avoid fakes with understated characteristics.

You can check the real speed and authenticity of the card using the SD Insight utility or PCMark on Android, by running a storage test before formatting.

Instructions for activation through ADB (No Root-Rights)

The most secure and common method of porting applications to the Xiaomi Redmi Note 7 does not require superuser rights. It is based on the ADB (Android Debug Bridge) tool, which allows you to send commands to the system directly from the computer. To start, you need to activate the developer mode on your smartphone. To do this, go to Settings → About phone and quickly click on the MIUI version seven times.

Once the developer menu is activated, a new section will appear in the settings list, "Additional" or "Extended Settings", and then you can find "Debug by" there. USB» And you activate it. When you connect your smartphone to your computer with a cable, you'll see a request for debugging permission on your screen, you'll check the "Always Allow" box and you'll confirm the action.

The next step is to connect your smartphone to your PC and start the command line, and in the terminal window, you need to enter a command to enter the device shell: adb shell. After you successfully connect, type in the sm list-disks command, which will show the ID of the external drive connected, usually it looks like disk:179.64 or a similar combination of numbers.

To convert the card to internal memory, you use the sm partition disk:XXX private command, where XXX is your card ID. Once you execute this command, the system will overwrite the partition structure. The smartphone can suggest a reboot. Once you turn on the storage settings, you will be able to transfer data. This method makes the card unreadable for other devices without re-formatting.

⚠️ Note: After executing the sm partition command, all data on the map will be irretrievably deleted, and the map itself will become unreadable on other devices without special reset.

Alternative method: Change manifest file

There is a less radical way that doesn't require map formatting, but allows you to force the transfer of individual applications, which involves editing the manifest system file or using special ADB commands to change the android:installLocation flag. However, in modern versions of MIUI, direct editing of system files without Root rights is difficult.

A more affordable option is to use the pm set-install-location 2 command via ADB. This command signals the system that the preferred place to install new applications is an external drive. Enter in the terminal: adb shell pm set-install-location 2. The value 0 returns automatic selection, 1 only internal memory, 2 external.

It's important to note that this is not a guaranteed method for all applications, software developers determine where their product can be located. Many modern services, such as WhatsApp, Telegram or banking applications, have a rigid binding to internal storage for security and stability, ignoring system preferences.

Comparison of transfer methods and their effect on the system

The choice of method depends on your goals: whether you need to make room for photos or for installing heavy games. Full formatting of the card for internal memory (Adoptable Storage) gives the most holistic experience, but deprives the drive of mobility. ADB-Preference teams are more flexible, but less effective in the fight for free space.

Below is a table comparing the main characteristics of different approaches to extend memory on the Redmi Note 7. It will help you weigh the pros and cons before you start manipulating.

Keep in mind that using a card as a system partition increases the wear and tear of the drive itself. Flash memory has a limited resource of overwrite cycles. Constant work with the application cache and databases can bring a cheap card out of action after 6-12 months of active use. Therefore, the use of quality A2 cards is critical to the durability of the system.

Possible problems and ways to solve them

Users can experience errors when migrating applications, and one of the most common problems is that they say, "Not enough space," even if there are free gigabytes on the map, because some of the space is reserved for service needs and partition alignment, and there may be errors when running the transferred applications.

If the application stops opening or doesn’t work properly after the transfer, try clearing its cache through the Settings → Applications → All Apps menu. In some cases, reinstallation of the program helps. If the system stops seeing the memory card, check the contacts in the slot or try formatting the drive on your computer to the exFAT or FAT32 file system (for cards up to 32 GB).

• 🔧 If you have installation errors, try turning off Wi-Fi and using your mobile network.
• 📱 Rebooting a smartphone often solves problems with displaying transferred icons.
• 🗑️ Do not manually delete files from folders Android/data on the map, it will disrupt the application.

⚠️ Note: If you have been manipulated by ADB The smartphone went into a cyclic reboot (bootloop), you need to reset to factory settings through the Recovery menu, holding the volume and power buttons.
