Owners of the budget but reliable Redmi 7 series often face a lack of built-in storage. MIUI operating system over time becomes cache, and modern instant messengers and social networks require more space to work. When free space runs out, the device begins to work slower, and installing new programs becomes impossible.
Fortunately, Xiaomi engineers have designed a microSD card slot to expand the storage available. However, standard Android settings don’t always allow you to drag a program to an external medium at a single click. In this article, we’ll discuss effective ways to solve the problem, including hidden system functions and the use of computer utilities.
You will learn how to properly prepare the drive, what risks exist when transferring system data and why some applications categorically refuse to move. Proper file system management will help to extend the life of your gadget and avoid constant struggle for every megabyte.
Preparation of external storage device for work
Before you start manipulating data, you need to make sure that the microSD card is good and formatted in the correct file system. Usually Android uses the FAT32 or exFAT file system for compatibility with most devices. If the card is new, the smartphone will suggest formatting it immediately after installing it in the slot.
Put the card into the tray using a special clip from the kit, and wait for the system notification. Go to the settings menu, select Settings → About Phone → Storage. This will show the total amount of internal memory and external drive. Click on your card name to see the available actions.
It's important to choose "Use as a portable storage" mode, which allows you to store photos, videos, music and documents, and transfer applications there. Internal storage mode on MIUI is often blocked or does not work correctly with the transfer of programs, so we focus on the standard portable mode.
⚠️ Note: The formatting process will completely destroy all data on the memory card. If it has important files, be sure to copy them to your computer before starting the procedure.
Once formatted, the system will assign a letter or a name to the drive, and now you can start cleaning the internal space, and it is recommended that you immediately transfer all heavy media files (photos, uploaded videos from messengers) to the external disk, making room for system operations.
Standard Transfer through Android Settings
The Android operating system provides a built-in mechanism for moving applications, but its availability depends on the developer of the specific software. If the author of the program allows the transfer, you can activate this feature without installing third-party software. Go to Settings → Apps → All applications.
Find a program you want, like a game or a social network, on the list, click on it to open a page of information, and if you can move it, it will have an "Change" or "Move to" button active. SD-Otherwise, the button will be grey or missing.
- 📱 Click on the "Change" button in the app menu.
- 💾 Select your microSD memory card from the list that appears.
- ⏳ Wait for the data copying process to be completed.
- ✅ Make sure that the storage line is"SD-map".
It's worth noting that even after the transfer, some of the data will remain in the internal memory, which are the system files and libraries that are needed to run it. APK-It's rare to completely free up internal storage in this way, but it's possible to win a few hundred megabytes.
Why is the transfer button inactive?
Using a Developer Mode for Forced Transfer
There is a hidden setting in MIUI, It allows you to force portability even for applications that don't officially support it. To activate, you need to turn on the Developer Menu. → On the phone and press quickly 7-10 once-in-a-paragraph MIUI", Until the message comes out, “You’ve become a developer".
Now go back to the main settings menu and find the Additional settings section. → For developers, scroll down to "Forcibly Allow Application Downloading." Activate this switch.
After the reboot, check your app settings again. Those programs that didn’t previously have a port button can now allow you to move them to SD. However, beware: system or important service applications that are ported this way may not work smoothly or stop updating through Google Play.
☑️ Pre-transfer check
Advanced features via ADB (for advanced users)
The most powerful way to manage memory is to use a debugging bridge ADB (Android Debug Bridge: This method requires connecting your smartphone to your computer via a computer. USB-It allows you to change the attributes of the application installation at the system level.
First, turn on USB debugging in the Developer menu. Connect your phone to your PC and start the command line in the ADB tool folder. Enter the adb device command and confirm the resolution on your phone screen. You can now manage the packages.
adb shell pm set-install-location 2This command sets the priority of installing new applications on an external map: 0 returns automatic selection, 1 returns internal memory only, 2 sets external memory.
adb shell pm move-package <name package>Find out. ID You can use the adb shell sm list-volumes command. private:179,64 or similar combination of digits.This method requires care, since an error in the name of the package can cause the application to fail.
⚠️ Attention: Use of teams ADB It can compromise warranty or cause system instability if you change critical system parameters.
Application limitations and compatibility
Not all apps can be moved, and this limitation is embedded in the Android architecture. System services, widgets, live wallpaper, alarm clocks and applications that require constant background access must remain in internal memory to ensure the stability of the Redmi 7 smartphone.
In addition, the speed of reading and writing memory cards is often lower than that of the built-in flash drive, running heavy games or resource-intensive programs from an external card can lead to increased loading time and the emergence of "freezes" (slowdowns), so it is necessary to transfer mainly media content and lightweight utilities.
| Type of application | Possibility of transfer | Recommendation |
|---|---|---|
| Cache games | Partial | It is better to transfer the cache through the game settings |
| Social media | Tall. | You can move, free up a lot of space. |
| Banking applications | Low/Prohibited | Keeping your internal memory for safety |
| System services | Impossible. | Do not move to avoid errors |
Also, when you remove the memory card, all the portable applications will stop working, and the system will give out errors when you try to run them, which creates inconvenience if you often change memory cards or use the same drive for different devices.
💡
Use UHS-I (U1 or U3) speed memory cards from trusted brands (Samsung, SanDisk, Kingston) and cheap cards can cause interface lags and data loss.
Alternative methods of vacating space
If you can't port applications or you don't get a good result, you should consider other optimization options. MIUI has a built-in Cleanup tool that finds duplicate files, old install packages and bloated cache. Regular use of this tool helps maintain order.
Many apps, such as Telegram, WhatsApp and Viber, allow you to change the way you save downloaded files directly in their settings. Go to the messenger settings, find the Data and Storage section and indicate the path to the SD-This automatically saves all new photos and videos to the external drive.
Another effective method is to use cloud storage, where services like Google Photos or Yandex.Disk can automatically upload photos to the cloud and delete them from the phone's memory, leaving only thumbnails, freeing up gigabytes of space without losing access to the archive.
💡
Comprehensive approach: the combination of application transfer, setting up ways to save in messengers and using the cloud gives the maximum result in the struggle for free space.
