Owners of the popular budget smartphone Xiaomi Redmi 7 often face a lack of built-in storage, the volume of which in the basic versions is only 32 GB. After installing mandatory system updates and pre-installed services MIUI, the user is left with very little space for personal needs. Installing games, messengers and photo accumulation quickly lead to critical memory filling, which causes a slowdown of the interface and the inability to install new programs.
The solution may be to use a microSD card, but the standard Android shell and MIUI often block direct transfer of executable files to an external medium without special manipulation. In this article, we will discuss in detail how to circumvent system limitations, format the drive correctly and make it a full-fledged extension of your deviceβs internal memory.
Understanding the workings of the Android file system will not only help you free up precious gigabytes, but also speed up your work. We will look at both standard methods and more advanced methods that require you to connect to a computer. It is important to follow the instructions consistently to avoid data loss or damage to the file structure.
Preparation of memory card and smartphone for work
Before you start transferring data, you need to make sure that your external drive meets the requirements of the system. For comfortable operation of applications from the memory card, it is recommended to use a microSD class at least Class 10 or UHS-I. Low read and write speed will lead to the fact that programs will run for a long time, and in games, textures and interfaces may slow down.
Insert the card into the corresponding Xiaomi Redmi 7 slot, which is usually combined with a tray for the second. SIM-Once the device is turned on, the system will automatically prompt the media to be formatted. At this point, it is important to choose the right type of formatting, because this depends on the ability to write applications.
If the system doesn't automatically offer formatting, go to the settings menu, and you need to find the partition that's responsible for the storage, and initiate manual cleaning of the map, and this will create a clean file structure ready to write system data.
- π± Make sure your smartphone is at least 50% charged before you start working with your file system.
- πΎ Back up all important photos and documents as formatting will remove all data from the card.
- π Use only quality memory cards from well-known brands such as SanDisk, Samsung or Kingston.
β οΈ Note: The formatting process is irreversible. All files on the memory card before the procedure will be permanently lost.
Standard Application Transfers through MIUI Settings
The MIUI shell provides basic memory management functionality, but it has significant limitations: it allows only cached data from some applications to be moved to an external medium, not the executable files themselves (.apk), which means that the main body of the program will still occupy space in the internal storage.
To perform a standard port, go to the Settings menu, then select the App item and then All Apps. In the list that opens, find the program you want, click on it and select the Memory option. If the Change button is active, you can select the memory card as your primary storage location.
Unfortunately, for most system applications and popular services like WhatsApp or Telegram, this feature is often blocked by developers or the shell itself.In such cases, the button will be inactive or absent, which requires the use of deeper customization methods.
It is worth noting that even if the transfer is successful, some of the data still remains in the system partition, which is done to ensure the stability of the Android operating system in the event of retrieval of the memory card.
Adoptable Storage Activation via ADB
The most effective way to turn a memory card into a full-fledged extension of internal memory is to use the Adoptable Storage feature, which is hidden from the average user in modern versions of MIUI, but can be activated via the Android debugging bridge (ADB) using a computer.
To start, you need to turn on the developer mode on your smartphone. Go to Settings β About Phone and quickly click 7 times on the MIUI Version. After the message about the successful activation, the Developer section will appear in the additional settings menu where you need to enable Debugging over USB.
βοΈ Preparation for ADB-team
Connect your smartphone to your computer through USB-On a PC, you need to run the command line in the tool folder. ADB. Enter a command to check the connection:
adb devicesYou'll see a debugging permission request on your phone screen, which you need to confirm. Once you've successfully connected, type in a command to format the map:
adb shell sm partition sdcard:0 privateThis command forcibly formats the card and combines it with the internal storage, and the system will perceive the external drive as an integral part of the memory, which will allow you to install any application on it without restrictions.
β οΈ Note: Once you execute the sm partition command, the memory card will be encrypted and cannot be read on other devices or computers without being reset.
Use Activity Launcher for Hidden Menus
If using the command line seems too complicated, there is an alternative method of activating the transfer of applications through hidden system activities.
Once installed, run the program and wait for the list of all activities to load. Type the word storage or memory in the search. You need to find the item associated with the storage settings, which is usually hidden in the deep layers of the system. The item you want to look for may be called com.android.settings.Settings$StorageSettingsActivity.
By going this route, you can access an extended memory management menu, where you can sometimes force the card to be formatted as internal memory, a method that is less reliable than ADB, because the presence of hidden menus depends on the specific version of MIUI firmware.
- π Look carefully for items with the word βStorageβ or βStorageβ in the list of activities.
- βοΈ The hidden menu interface may differ from standard settings and may not be adapted for touch control.
- π On newer versions of Android, access to Adoptable Storage is often closed through this method.
Using third-party activity launchers requires caution: Do not change settings that you do not know the purpose of, so as not to disrupt the stability of the operating system.
π‘
If the phone starts to run slower after formatting via Activity Launcher, go back to the storage menu and select the "Use as Portable Storage" option to undo the changes.
Transfer of media files and messenger cache
Even if direct transfer of executable application files is not possible, you can significantly free up internal memory by transferring heavy media files and cache. Messengers like Telegram and WhatsApp tend to accumulate gigabytes of images and videos, which are stored in internal memory by default.
In the settings of the Telegram itself, you can specify the path to the memory card for storing the cache. β Data and memory β Path to the files and select yours SD-This will instantly free up space in the system partition by moving temporary files to an external medium.
For photos and videos, you should also change the camera settings. Open the Camera app, go to the settings and select saving the photo on the camera. SD-This will prevent the internal memory from filling up quickly during active shooting.
| Type of data | Default location | Recommended seat | Saving space |
|---|---|---|---|
| Photos and videos | Internal memory. | SD card | Tall. |
| Cash messengers | Internal memory. | SD card (in settings) | Medium |
| Music and films | Internal memory. | SD card | Very high. |
| System files | Internal memory. | Don't move | 0% |
Regular cleaning of cache and transfer of archives allow to keep the smartphone in working condition without the need for radical measures to flash or use complex commands.
Possible problems and solutions
Users may experience a variety of errors in the process of memory expansion, and it is common for applications to become unstable or crash when formatting the card as internal memory, which may be due to slow card reading speed or damage.
If you notice a slowdown of the Xiaomi Redmi 7, try extracting the memory card and checking it on your computer using the SD Memory Card Formatter utility.Perhaps the drive has physical sector errors that interfere with the correct operation of the system.
