Owners of the popular smartphone Xiaomi Redmi Note 7 Often face a lack of internal memory, especially if the device has a configuration 3/32 GB: Installation of modern applications and games quickly fills the available space, which leads to slowdown of the interface and the inability to update programs. Expanding memory becomes a critical task for comfortable use of the gadget in the computer. 2026 year onwards.
Fortunately, this model supports installation of microSD cards up to 256 GB or more, which opens up wide possibilities for data storage. However, the standard MIUI system has its own features of working with external storage, and simple file transfer does not always solve the problem of lack of space for applications. In this article, we will discuss in detail how to correctly use an external drive, turning it into a full-fledged continuation of the internal memory of the device.
There are several methods to solve the problem, from standard Android settings to advanced manipulation through debugging. USB. It is important to understand that the transfer of system applications to SD-The root-free card has restrictions depending on the version. MIUI We'll look at the most effective ways to help you free up precious gigabytes of embedded storage.
Preparation of a memory card and smartphone
Before starting any manipulations, you need to make sure the quality of the drive used. To work in conjunction with the Redmi Note 7 smartphone, it is recommended to use memory cards of the Class 10 or higher standard, preferably the UHS-I series, since the read and write speed directly affects the performance of installed applications. The use of slow cards can lead to "freezes" and long downloads of programs.
It is also crucial to save all important data from the memory card to your computer or to the cloud. The process of setting up the storage often requires formatting, which will result in the complete removal of all information. Make sure that the smartphone is charged at least 60% to avoid turning off during the process of writing system files.
☑️ Pre-commencement checks
Once the card is physically installed in the slot, the system will suggest you choose how to use the drive. The standard mode "Portable storage" allows you to store photos, videos and music, but does not allow you to install applications there.
Setting up SD-maps as internal storage
In the Android operating system on which it works MIUI, Adoptable Storage is a feature that allows you to combine internal memory and SD-However, in the shell from Xiaomi, this option is often hidden from the user. If the map insertion does not appear, or there is no item "Use as internal storage", you will have to use an alternative method through the engineering menu or ADB.
The standard path to check first is: Go to Settings → About Phone → All specs and quickly click on MIUI Version several times to activate Developer Mode. Then, in advanced settings, an option may appear Additional → For Developers → Forced Application Portability. Activating this switch is the first step to success.
⚠️ Note: After formatting the memory card for internal storage, it will be encrypted and cannot be read on other devices (cameras, computers) without re-formatting.
If the standard settings don't work, you can try the hidden method through the test menu. Type ##6485## into the "caller" to log into the engineering menu, but the functionality is limited to diagnostics. A more reliable way is to use the ADB commands, which will be discussed below, since they allow you to force the drive setup wizard to run.
Why is Xiaomi hiding this feature?
Using ADB for Forced Transfer
The most effective and effective way, working on almost all versions. MIUI Global and China, is the use of Android Debug Bridge tools (ADB). This method requires connecting the smartphone to the computer through USB-It allows you to send commands to the system that are not available through the standard interface.
To start, you need to enable debugging via USB. Go to Settings → Advanced Settings → For developers and activate the USB debugging switch. When you connect to a PC, a request for debugging permission will appear on the smartphone screen - be sure to confirm it by ticking the "Always Allow from this computer".
Once connected, open the command line on your computer in the ADB folder and enter the command to check the connection: adb devices. If a device with a serial number appears in the list, the communication is established successfully. Next, you need to execute a command to call the storage setup wizard: adb shell pm set-install-location 2. This command tells the system that by default new applications should be installed on external storage.
- 📱 Checking command: adb shell pm get-install-location (must return value 2).
- 💾 Installation command: adb shell pm set-install-location 2 (default installation on the device) SD).
- 🔄 Reset command: adb shell pm set-install-location 0 (return to internal memory).
It is worth noting that this command sets preference, but does not transfer already installed applications automatically. To transfer existing programs, you need to go to the settings of each application individually. In addition, some system applications and programs with widgets may not support portability, which is a limitation of the Android platform itself.
Transfer applications through system settings
After completing the preparatory steps, you can start moving data directly. Go to the Settings menu → Applications → All applications. From the list, select the program you want to move, such as a heavy game or a social network. If transfer is possible, the Memory or Storage button will be active in the application menu.
In the window that opens, you'll see the memory distribution if the memory card is properly configured as internal or is connected via a link. ADB, There will be a button "Change" or "Move to" SD-Clicking on it will trigger the migration of data, and the duration of the operation depends on the size of the application and the speed of your memory card.
| Type of data | Can we move it? | It's still in my memory. |
|---|---|---|
| APK file of the application | Yes (partially) | No. |
| Cash and user data | Yes. | No. |
| System libraries | No. | Yes. |
| Desktop widgets | No. | Yes (requires internal memory) |
It is important to understand that not all applications support full portability. Software developers may prohibit installation on external media for security or stability reasons. In such cases, the move button will be absent or inactive, and it is almost impossible to circumvent this restriction without root rights.
Working with multimedia files and cachem
Even if you can't move the apps themselves, you can actually de-storage your internal memory by transferring media files and cache. VK, They store a lot of images and videos in internal memory, and you can set the settings for those applications to point to folders on the back of the file. SD-card to save downloaded files.
For system folders such as Downloads, Camera and Dictator, it is also recommended to change the save path: Open the standard MIUI Explorer or any file manager, go to settings and select the main folder for new files, which will prevent the internal /data partition from being filled with personal photos and documents.
Special attention should be paid to the cache of browsers and streaming services. Periodic cleaning of the cache or its transfer (if the application allows) helps to keep the system in good shape. On the Redmi Note 7 with its Snapdragon 730 processor, a fast memory card can even speed up the loading of some interface elements, if the cache is stored on it.
⚠️ Note: Do not delete files with the extension.obb or.data from Android folders on the memory card manually if you are not sure about their purpose - this can lead to a reset of progress in games.
Possible problems and solutions
Users may encounter various errors during the setup process. One of the most common is a message"SD-This often indicates poor memory card quality or that the file system was damaged by improper extraction, in which case the card is formatted via PC to exFAT format or FAT32.
Another problem is that applications stop working after the card is extracted, and it's normal to use internal storage, because the executable files are physically on the media, and if the card is retrieved, the system labels the applications as "error," and the solution is one: don't retrieve the card without first returning the applications to internal memory.
💡
Use SD Maid or Files by Google to analyze your space, which helps you find hidden files and duplicates that often remain after you delete your apps.
If you've been manipulating your phone and it's not stable, it makes sense to reset the storage settings, so you can turn off the USB debugging and reboot the device in the developer menu, and at the very least, you can reset the phone completely to factory settings, but that requires you to re-install all the programs.
💡
Stability of the Redmi Note 7 with applications on SD-The card is directly dependent on the quality of the memory card. Savings on the drive can lead to data loss and unstable system operation.
