Owners of the popular Xiaomi Redmi Note 7 smartphone often face a lack of built-in storage, especially in the 32 or 64 gigabyte version. Installing heavy games and instant messengers quickly fills the available space, forcing the system to run slower and blocking the installation of new programs. Transferring data to an external drive seems like a logical solution, but standard MIUI settings often hide this ability from the user.
To make matters worse, modern versions of Android shell and Xiaomi firmware by default do not allow executables to be moved to an external medium, for security and stability, but for the experienced user, such restrictions are only a temporary inconvenience.
In this guide, we will take a look at all the ways you can expand storage, how to prepare the media, what hidden developer menus exist, and why a normal port might not work without root rights or special emulation.
Limitations of the MIUI and Android File System
Since Android 6.0, Google has implemented Adoptable Storage, which allows you to format your memory card as part of your internal storage, but many manufacturers, including Xiaomi, have blocked this feature at the software level, and as a result, when installing a microSD card in Redmi Note 7, the system suggests using it only as portable storage for photos, music and documents.
This policy is driven by the company’s desire to ensure the stability of the operating system: Cheap memory cards can have low read and write speeds, which leads to applications freezing if their executable files are located on a slow medium. The internal memory of a smartphone usually runs at significantly higher speeds than even the fastest UHS-I cards.
⚠️ Warning: Forced transfer of system components to a slow memory card can lead to unstable interface operation and increased application load time.
However, for many users, volume is more important than micro-latency, and if you’re willing to sacrifice some of the speed to install more games, there are ways to bypass the standard MIUI Global or EU shell limits. It’s important to understand that standard Settings menus don’t do that in a single click.
Preparation of memory card and backup
Before you start any manipulation of the file system, you need to properly prepare the external drive. Poor-quality card can cause data loss or damage to the partition table. For Xiaomi Redmi Note 7, it is recommended to use cards up to 256 GB with a speed class of not lower than Class 10 or A1/A2 marking.
The preparation process requires full formatting, which means deleting all information, so the first step is to back up all important files, copy photos, contacts and documents to your computer or to the cloud, which is a critical step, because the media will be completely cleared during the setup process.
☑️ Preparation for data portability
Once you back up, insert the card into the smartphone slot, the system will suggest formatting it, select "Use as a portable storage" option at the beginning to check the media's performance, and make sure the phone correctly determines the full volume and speed of the recording.
Emulation of internal memory through ADB
The safest way to avoid superuser rights (Root) is to use a debugging bridge. ADB. This method forcibly activates a hidden function of the system that allows you to format the card as internal memory, USB-cable and drivers for Xiaomi.
First, you need to activate the developer mode on your smartphone. → About the phone and seven times quickly click on the build number MIUI. After the message “You became a developer” appears, go to the advanced settings and turn on “Debugging by” USB». Also in the “For Developers” menu, find the “By default download” item. USB-Configuration and select MTP.
Connect the phone to your computer and start the ADB console. Enter a command to check the connection:
adb devicesIf the device is determined, execute the command to force the function of acceptable storage:
adb shell sm set-force-adoptable trueThen go back to the storage settings on your phone. Now, when you try to format a map, the system should suggest the option "Use as internal storage." Select that and wait for the migration process to complete.
💡
Use the original. USB-cable to connect to a PC to avoid connection breaks during command transfer ADB.
Use of third-party utilities for transfer
If ADB seems too complicated, you can use specialized applications from Google Play, programs like App2SD or Files2SD analyze installed packets and try to move their cached data to an external medium, but the effectiveness of such methods depends heavily on the version of Android and security policy.
Most modern applications don’t allow you to move your executable files (.apk) without root rights. They can only transfer a portion of the data (obb files, cache), which frees up space, but doesn’t solve the problem completely.
- 📱 App2SD: Allows you to analyze memory and move supported applications in one click.
- 📂 Files2SD: Specializes in transferring large data files and game cache to the map.
- 🚀 All-In-One Toolbox: Cleaning combine that includes app placement management functions.
It is worth noting that after a system update or reboot, some of the displaced data can return to internal memory, which is a normal Android security behavior that prevents compromised or unstable applications from running from external media.
Comparison of methods of memory expansion
The right way to do this depends on your technical skills and goals, and here is a table comparing the basic methods of data porting to the Xiaomi Redmi Note 7, which will help you determine whether you should risk system stability for additional space.
| Method | Demands a Root. | Efficiency | Risk of instability |
|---|---|---|---|
| Standard transfer | No. | Low (media only) | Absent. |
| ADB (Force Adoptable) | No. | Tall. | Medium. |
| Third-party utilities | Partially. | Medium | Low. |
| Complete flashing. | Yes. | Maximum | High-pitched |
As you can see from the comparison, ADB is the middle ground, it doesn't require a root, but it gives you access to the right functionality. Complete flashing to custom versions of MIUI or LineageOS gives you maximum control, but can deprive you of the guarantee and the ability to use banking applications without additional configuration.
Possible problems and solutions
Users may encounter various errors in the process of porting applications, and the message “Can’t move the application” is often used, meaning that the developer has banned installation on external media in the application manifesto, and this restriction can only be circumvented by root rights and using special modules.
Another common problem is that widgets or tags of displaced applications disappear from the desktop, and once the map is formatted as internal memory, the shortcuts can get lost, in which case simply restarting the device or re-additioning widgets through the MIUI widget menu will help.
⚠️ Warning: If your phone is slowing down after porting apps, return the card to portable storage mode. MicroSD card reading speeds can slow down the entire system.
Also worth remembering is the physical wear and tear of memory cards, which have a limited resource of overwriting cycles, the constant operation of applications from the card (especially the cache of browsers and instant messengers) can quickly bring the media down, regularly check the health of the card with special utilities.
Optimizing storage on Redmi Note 7
Even without the apps themselves, you can make room, and MIUI has a built-in cleanup function, but it often only deletes temporary files, and a more efficient way to manually transfer folders of photos and videos to the DCIM on the map, and in the camera settings, specify saving new images immediately to the microSD.
Many users forget about messaging. Telegram and WhatsApp can take up tens of gigabytes. Go to the settings of each application, find the item "Data and memory" and limit the auto-save media files. Clear the cache of these programs regularly through Settings → Applications → Application Management.
Secret folder in MIUI
Using cloud services also helps keep internal memory free. Set up sync with Google Photos with Free Space, which will delete local copies of your images, leaving them in the cloud, available anytime with the Internet.
