Despite its popularity in the budget segment, Redmi 7 smartphones often face a critical shortage of internal storage. Built-in 32 or 64 gigabytes in modern realities is not enough to install all the necessary social networks, messengers and navigation programs. The MIUI system installed on top of the Android operating system itself takes up a significant part of the space, leaving the user only a small share for personal needs. When the free space ends, the device begins to work slower, and new programs simply refuse to install.
The natural solution is to use a microSD memory card. However, Xiaomi’s standard settings allow only photos, music and video files to be stored on an external medium. The default application installation takes place in internal memory, which quickly leads to overflow of the system partition. Many users wonder whether it is possible to bypass this restriction and make the phone perceive the flash card as a full-fledged extension of the system disk.
In this article, we will discuss in detail all available methods of data transfer, including hidden developer functions and the use of third-party software. You will learn what risks exist when formatting a map as internal storage and how to properly prepare your device for working with large amounts of data. Proper organization of the file structure will significantly extend the comfortable life of your gadget without the need to buy a new model.
Preparation of memory card and smartphone for work
Before you start any manipulation of the file system, you need to make sure the quality of the storage device used. Cheap memory cards of unknown brands can cause data loss and unstable applications. To install programs, it is recommended to use drives of Class 10 or higher speed, as well as UHS-I standards. Read and write speed directly affects how quickly games and utilities open after they are transferred.
Insert the memory card into your Redmi 7 slot and wait for the notification of the new device’s connection. The system will suggest using the drive to store photos and media files, which is the standard scenario. At this stage, it is important to check whether the card is correctly identified and full memory is available. If the device sees the error drive, it may need to format it on a computer in the FAT32 or exFAT file system.
Back up all the important data on the memory card, as the next steps will require its complete cleanup. the process of preparing the storage for working with applications permanently deletes all current information. Make sure that the battery charge of the smartphone is at least 50% to avoid sudden shutdown during critical operations with partitions.
- 📱 Make sure the memory card is inserted before clicking and is defined in the About Phone menu".
- 💾 Save all important photos and documents from a flash card to your computer or cloud storage.
- ⚡ Check the speed of writing the card using the utility SD Insight or analogues.
- 🔋 Charge the battery of the smartphone to at least half for safe work.
💡
Use memory cards up to 128GB for maximum compatibility with older versions of MIUI, as large volumes may not be correctly defined by the system without kernel patches.
Standard method of transfer through MIUI settings
The Android operating system in the MIUI shell provides basic functionality for memory management, but its capabilities are limited. Not all installed programs support transfer to an external drive by standard means. This is due to Google's security policies and application optimization, which require high file access speeds, which a microSD card can not always provide.
To check if you can port a particular application, go to the settings menu and select "Applications." From the list of installed programs, select the one you want and click on "Memory." If the program supports data migration, you will see an active button "Change" or "Move to" SD-Otherwise, the button will be missing or inactive, indicating that it is impossible to transfer without using special methods.
It's worth noting that even if you successfully transfer some of the application's data, it's still in internal memory, which is the system files and cache needed to run the program correctly, and it's impossible to transfer it completely using standard tools only for most modern heavy-duty applications, such as social networks or navigators.
If the standard method has failed, don't despair. There is a deeper level of system customization that allows you to bypass the manufacturer's limitations. However, before moving to complex methods, it is worth trying to clean the cache of the mobile application to reduce its volume and increase the chances of successful migration.
Activate Adoptable Storage through ADB
The most effective way to get the Xiaomi Redmi 7 to perceive the memory card as part of internal memory is the Adoptable Storage feature.This technology was introduced in Android 6.0, but many manufacturers, including Xiaomi, hide it in the standard interface. To activate this feature, you will need to use a computer and debugging tool ADB (Android Debug Bridge).
The first step is to activate the developer mode on your smartphone. To do this, go to the About Phone menu and quickly click on the MIUI version seven times. Once you have become a developer, go back to the main settings menu, select "Additional" and then "Development by USB" menu, and activate it by confirming the action in the dialog box that appears.
adb shell pm set-force-true-adoptable 1Once you connect your smartphone to your computer and you input a command, you need to format your memory card as an internal storage through the phone's settings menu. The system will warn you that the card will be encrypted and cannot be used on other devices without formatting. This is an important security point that protects your data from theft in the event of card loss.
Risks of using Adoptable Storage
Using third-party utilities for memory management
If you think it's too difficult to use the command line, you can use specialized applications from the Google Play store. Programs like App2SD or All-In-One Toolbox automate the process of analyzing and transferring data, they scan the device for applications that can theoretically be moved, and provide a convenient interface for memory management.
However, without root rights, these programs are limited in functionality, which can only show which applications support the transfer, or clear the cache. Real file structure changes and forced data movement often require superuser rights, which can lead to the loss of warranty on the device.
Some utilities offer a "Link2SD" feature that creates a reference file structure, which allows the system to think that the application is in internal memory while physically its files are located on a microSD card. This method requires creating a special partition on the memory card, which also leads to the deletion of all data on it.
- 🛠 Download the proven memory management utility from the official app store.
- 🔍 Scan the system for applications that support external media transfer.
- 📂 Backup your system before using features that require root access.
- ⚙️ Use the cache cleanup function to free up space without carrying heavy files.
☑️ Checking readiness for transfer
Comparison of data storage methods on Redmi 7
The choice of memory management method depends on your needs and technical background, each method has its advantages and disadvantages, which must be considered before starting work. Below is a table that helps to determine the best option for your situation.
| Parameter | Internal memory. | Portable storage | Adoptable Storage |
|---|---|---|---|
| Speed of operation | Tall. | Medium/Low | Depends on the card. |
| Security of data | Tall. | Medium | High (encryption) |
| Possibility of transfer to another phone | No. | Yes. | No (no formatting) |
| Stability of the system | Maximum | Tall. | Medium (risk of failure) |
Using the card as a portable storage device is the safest option for beginners, and you can remove the flash card at any time and paste it into your computer or other phone, but it doesn't solve the problem of not having enough space to install new applications, it only allows you to store media files.
Adoptable Storage provides the most flexibility to turn a budget smartphone into a device with a large amount of memory, but it is worth remembering that the wear of the memory card when applications are active is much faster than when you simply store photos.
💡
The optimal balance between performance and volume is to store system applications in internal memory, and user data and media on a memory card.
Optimization and maintenance after the transfer
After successful application porting or activation of the combined memory function, a number of optimization procedures must be performed; the system must re-index the files, which may take some time; during the first hours of operation of the device, increased battery consumption and heating of the case are possible in the new mode.
Regularly check the status of the memory card through the settings menu. File fragmentation can reduce the speed of reading data over time. Periodic backup of important data to an external hard drive or to the cloud will help avoid loss of information in the event of a failure of the drive. Memory cards are consumable and have a limited life.
⚠️ Warning: Never remove a memory card if it is formatted as internal storage without resetting or back formatting.This will result in the inability to run displaced applications and loss of their data.
To maintain high speed smartphone recommended every few months to clear the cache of system services and remote applications. Even with a large amount of external memory, overflowing the system partition temporary files can slow down the MIUI. Use built-in cleaning tools or proven third-party utilities.
Why do applications run slower from a memory card?
Possible problems and ways to solve them
Users may encounter various errors during data transfer, most often the message “Not enough memory” even when there is free space on the map, because the transfer operation requires a temporary space in internal memory, which should be approximately the size of the application being transferred.
Another common problem is the disappearance of widgets or failure of notifications from portable applications, which occurs because the system cannot find executable files on the old path, in such cases, helps to re-install the application or forced stop and clean the data of the Package Installer service.
⚠️ Warning: If after transferring applications, the phone begins to reboot frequently or freeze on the logo, immediately remove the memory card (unless it is formatted as internal) or boot into Safe Mode to remove problem programs.
In the case of ADB You may have connection errors. Make sure that your computer has the current Xiaomi drivers installed and the debugging icon is displayed in the smartphone status bar. USB-cable is also critical for stable connection.
