Owners of the popular budget smartphone Xiaomi Redmi 7 often face a lack of built-in storage, as 32 or 64 gigabytes are quickly filled with modern heavy applications and multimedia. the standard MIUI file system by default does not allow you to fully transfer installed programs to an external drive, limiting the user to only moving photos and videos. However, there are proven methods to bypass this limitation and make the system perceive the memory card as part of internal storage.
To accomplish this, you will need a high-quality memory card of the Class 10 or higher standard, since the speed of reading and writing directly affects the speed of installed programs. Trying to run heavy applications from a slow flash drive can lead to system freezes, so the quality of the drive plays a critical role. In this article, we will discuss safe ways to expand memory without the need to obtain root rights, and also consider more complex methods for advanced users.
Before you start any manipulation of system files or storage settings, you need to create a full backup of all important data. The process of formatting the card as an internal storage will irrevocably delete all the files that are on it, so ignoring this step can lead to the loss of photos and documents.
Preparation of memory card and smartphone for work
The first step is to physically install the drive properly and check its status in the system.Put the microSD card into your Redmi 7 slot and wait for the notification of the new device's connection. Go to the Settings menu → About Phone → Storage to make sure the system correctly determines the volume and type of connected drive.
If the card was previously used on other devices, it could have a file system that is incompatible with Android requirements for the applications to work. In this case, the system itself will suggest formatting the drive, but for our purposes it is better to do this manually through the settings menu. Select the option “Clean” or “Format” to delete all the unnecessary files and prepare a clean structure.
- 📱 Make sure your smartphone is at least 50% charged to avoid being turned off during formatting.
- 💾 Check the card for errors with your computer before installing it on your phone.
- 🔒 Remove all important data, as formatting will destroy all the information on the flash drive.
Once prepared, it’s important to understand that the memory card’s speed becomes the new “narrow neck” of your smartphone. The built-in eMMC memory in Redmi 7 runs faster than most budget microSD cards, so application performance can decrease slightly. However, it is often the only option to free up space in the system and install additional programs.
💡
Use memory cards from proven brands like SanDisk or Samsung, as cheap counterparts often fail when app data is intensively written.
Adoptable Storage Method through ADB Teams
The most reliable way to get Xiaomi Redmi 7 to install applications on an SD card is to use Adoptable Storage mode. This is hidden by the manufacturer in the MIUI shell, but it can be activated through USB debugging and ADB computer commands. This method allows the system to consider an external card as part of the internal storage, encrypting the data for security.
To start, activate the developer menu. Go to Settings → About Phone and quickly click on the MIUI version seven times until the message “You’re a developer” appears. Then, in the advanced settings, find “Developers” and turn on the option “Debug by USB”.
adb shell pm set-install-location 2Once you connect your smartphone to your computer and start the command line with administrator permission, enter a command to change the installation priority. The number 2 at the end of the command indicates the priority of external storage. However, simply changing the priority is not enough - you need to format the card exactly as internal memory, which is done through a hidden menu or specialized utilities.
☑️ Pre-activation check ADB
It is important to note that once this mode is activated, the memory card will be encrypted and cannot be read on other devices without being reset. If you decide to return everything as it was, you will have to format the drive again, which will lead to data loss.
⚠️ Warning: Once the card is in internal storage mode, it will not be possible to remove it without data loss and application performance.
Use of third-party applications for transfer
If you find using the command line too difficult, you can use specialized utilities from Google Play. Apps like App2SD or Files by Google help analyze memory and offer options for data transfer, although their capabilities in MIUI are limited by system access rights.
These programs can't force a system to install an application on a flash drive unless the developer has it in mind, but they do a great job of moving cache and large files. You can manually move heavy data folders, making room for the main programs to run. This is less efficient than Adoptable Storage, but safer for inexperienced users.
- 📂 Analyze memory regularly to remove unnecessary messenger cache.
- 🔄 Use the Cleanup feature in Xiaomi’s built-in Security app.
- ⚙️ Some launchers allow you to transfer your settings and plugins to an external drive.
Consider that many modern apps like WhatsApp or Telegram allow a way to save media files in their internal settings. By changing these settings, you automatically direct the incoming data to the SD card without resorting to system tricks. This is a standard method that is guaranteed to work on any version of Android.
Why aren’t all apps being ported?
Configuring data storage in specific applications
Even without deep system changes, you can significantly relieve internal memory by configuring popular apps correctly. On Telegram, go to Settings → Data and Memory → The path to files and select your SD card, which will allow the cache of channels and chats to take up space on an external medium.
YouTube Go or Netflix also has a folder for downloading videos for offline viewing, which takes up gigabytes of internal memory by default, but redirecting them to a flash drive solves the problem of space shortage, and similar settings are available in navigators like Yandex.Navigator or 2GIS, where you can download maps of regions to an external drive.
| Annex | The path to adjustment | What's transferable | Impact on memory |
|---|---|---|---|
| Telegram | Settings → The path to files | Photos, videos, documents | High. |
| Camera. | Camera settings → Save | Photo and video shooting | Critical |
| Spotify | Settings → Storage | Cash music. | Average. |
| Google Maps | Settings → Storage of cards | Offline maps | High. |
Regularly checking these settings is essential, as after updating applications, file paths can be reset to standard ones. Make sure that the save path always points to an external drive, especially after major MIUI updates.
💡
Reconfiguring the save paths in the applications themselves is the safest way to free up space without the risk of data loss or breach of warranty.
Possible problems and ways to solve them
When you move applications or activate internal memory, users may experience errors, often the system says "failed to move" or the application stops running after the transfer, which may be due to a slow card write speed or file table corruption.
If applications are unstable, try formatting the card again by choosing the exFAT file system over FAT32 if the device supports this format, and the incompatibility of a particular application with external storage may also be a problem, in which case it will have to be returned to internal memory.
- 🐌 Slow operation of the interface indicates a low speed memory card.
- ❌ Application Launch Errors Require Their Return to Internal Storage.
- 🔋 Increased battery consumption may be a consequence of constant work with SD card.
In some cases, cleaning the Media Storage cache helps. Go to Settings → Apps → Show all applications → Sort by name (or system processes) → Media service and clear its data. This will cause the system to re-index files on the memory card.
⚠️ Warning: If after transferring applications, the smartphone began to constantly restart, immediately remove the memory card or turn it off through the storage settings to enter safe mode.
Comparison of methods of memory expansion
The choice of method depends on your technical skills and goals. Using ADB gives the maximum result, turning the flash drive into a part of the system, but requires caution. Set up individual applications is safer, but gives only a partial effect of freeing up space.
For most Redmi 7 users, a combination of methods would be best: manually transferring media files and cache of heavy applications, and using cloud storage for rarely used data.
Remember that your internal memory will always be faster and more reliable than any external drive, so don’t fill it up completely even after expansion – leave 10-15% free space for the operating system and temporary files to work properly.
