Owners of the budget but reliable Redmi series smartphones often face a shortage of built-in storage. Xiaomi Redmi 7, released in 2019, usually comes with 32 or 64 gigabytes of internal memory, of which a significant part is occupied by the system and preinstalled software. Installing modern “heavy” games and multimedia applications quickly leads to overflow of storage, which causes slowdown of the interface and inability to install updates.
Fortunately, the device features a microSD card slot that allows you to expand the available space. However, the standard MIUI shell has its own features of working with external drives. Users often wonder how to get the system to use the card to install programs, not just to store photos. In this article, we will examine all available methods, from standard settings to using special commands, so you can effectively manage your gadget’s memory.
It is worth noting that the data transfer process does not always go smoothly due to Android security policies.Some system applications and important Google services cannot be moved to external media for reasons of stability.
Before you start active, you need to properly prepare the external drive. SD-The card can cause your phone to freeze or data to be lost.Make sure you are using a certified product from a reputable manufacturer with a speed class of at least 10.
Preparation of SD-card for work in MIUI
The first step is to physically install and programmatically initialize the memory card. Insert the microSD into the smartphone tray, matching contacts with guides, and wait for the notification system. Xiaomi Redmi 7 automatically prompts you to format the drive, and this action must be performed for the file system to work properly.
Formatting completely clears the card by deleting all previously stored files, so back up important data on your computer or in the cloud in advance. The process takes only a few minutes, after which the system assigns a letter to the drive and makes it available for recording.
💡
Use memory cards up to 128GB for maximum compatibility with the Redmi 7 memory controller, although the model supports large volumes.
After formatting, it is important to check the status of the drive in the settings menu. Go to Settings → Storage and make sure the system sees the card as “Portable Storage.” It is this mode that allows you to flexibly manage files, although it limits the direct portability of some applications without additional manipulation.
If the card is defined as “Internal Storage” (which is rare in newer versions of MIUI without root rights), it becomes part of the system partition, and it will not be retrievable without losing data.
Note the speed of writing: if the card is slow, the phone interface can slow down when accessing data. Speed class plays a critical role in the performance of the games installed on the map.
The standard method of transfer through settings
There is a built-in mechanism for moving data in the MIUI shell, but it is not available for all programs. It decides which applications can be moved based on their architecture and developer requirements. To check whether this feature is available, open the settings menu and select "Applications".
In the list of installed programs, find one that takes up a lot of space, such as a social network or a navigator. Click on the application name to go to the control menu and look for the "Move to the control menu" button. SD-If the button is active (not grey), you can safely press it and wait for the process to be completed.
⚠️ Note: If the displacement button is missing or inactive, it means that the application developer has prohibited its installation on an external medium. USB.
And you have to remember that when you move it, you still have some of the data in your internal memory, which is the system files and libraries you need to run quickly, and you rarely get it completely freed up by standard methods, but even transferring the cache can be very effective.
For some games and heavy applications, the system may suggest moving only a fraction of the data, in which case the main executable file will remain inside and resources (graphics, sounds) will be downloaded from the card, which helps save space, but requires that the card is always on the phone.
☑️ Pre-transfer check
Use of the function "Memory by default"
In earlier versions of firmware MIUI And some versions of Android there was a convenient option that allows you to assign SD-The default location for all new applications is the map, and in current versions of the system, this feature is often hidden or deleted, but it is worth checking if it is available.
To search for this option, go to the Settings section → Storage. If you have a "Preferred Installation Location" or similar item on the menu, select the value «SD-After that, all new programs from Google Play will try to install on an external drive.
However, it is not a good idea to rely on this method completely, because many modern applications ignore system preferences and still install them in internal memory, and some services can become unstable if the memory card is removed or damaged.
If you don’t find this setting on your menu, it doesn’t mean the phone is faulty. Android’s security policies of recent years have strictly regulated the use of internal and external drives, limiting the ability to automatically transfer.
Regular cleaning of the cache remains a necessary procedure.
Why did the choice of memory disappear?
Forced transfer through developer mode
For advanced users who want to gain more control over the file system, there is a method of activating hidden functions through the developer menu, which allows you to unlock the ability to migrate those applications that are standardly blocked for migration.
First, activate the developer mode. To do this, quickly click on the build number seven times in the Settings → About Phone section. After the “You’ve become a developer” notification appears, go back to the main settings menu and find “Additional” → “Developers”.
In the list of engineering options, find the option "Force allow apps on external." Activate this switch. After that, you need to restart the device so that the changes take effect.
⚠️ Attention: Forced transfer of system applications or Google services can lead to phone malfunction, errors and interface instability. Be selective in choosing programs to move.
Once you reboot, go back to your application settings and check the list, and those programs that didn't have a port button before can now be migrated, but the success of the operation is not 100% guaranteed, because it depends on the structure of the application itself.
Use this method with caution. If the application stops running or works with errors after transfer, return it to internal memory through the same settings menu.
💡
Activating developer mode is the only secure software way to circumvent the limitations of MIUI without obtaining root rights.
Transferring multimedia data and application cache
Even if you can't move the app itself, you can almost always migrate its data. Many programs, especially instant messengers like Telegram and WhatsApp, and social networks, store huge amounts of media files in internal memory by default.
To free up space, use the built-in file manager MIUI Find folders with app names (usually in the root or in the folder) Android/media) and move the contents to SD-Some apps allow you to change the way you save in your internal settings.
For example, in Telegram you can go to Settings → Data and memory → Path to files and choose SD-After that, all new downloadable files will be saved to an external drive without taking up precious internal space.
The same thing happens with the camera, so make sure that the camera settings choose to save photos and videos to the memory card, so you can take thousands of pictures without worrying about filling the system partition.
Check Downloads regularly, and often it accumulates APK installation files, documents, and pictures that are no longer needed but take up space, and can be safely transferred to a map or deleted.
💡
Use the Cleanup feature in Xiaomi’s Security app to quickly find large files and duplicates taking up space.
Table of compatibility and transfer limitations
Understanding which types of apps can be moved and which ones should be left out will help avoid problems. Below is a summary table showing how different categories of programs behave when trying to migrate to Redmi 7.
| Type of application | Possibility of transfer | Impact on speed | Recommendation |
|---|---|---|---|
| System services | Impossible/Dangerous | Critical slowdown | Leave it inside. |
| Social media | Partially (cache) | Minimum | Transfer media |
| Offline maps | Complete transfer | Depends on the card. | Recommended |
| Hard games | Partially (OBB cache) | Long loads | Just the cache. |
As you can see from the table, full portability is not always available, system components must stay on a fast internal drive to ensure the stability of the Android operating system.
Games with large graphics (files) OBB) They can often be moved, but when they start, they can take longer to load if the read speed is too fast. SD-You can use cards with a label. A1 or A2 to minimize delays.
Social media is best cleared of cache regularly, as it tends to grow to gigabytes of temporary files that carry no critical value and are easily recoverable.
