Transfer applications to memory card on Xiaomi Redmi 7

Budget smartphone owners often face a lack of built-in storage. The Redmi 7, released in 2019, is typically equipped with 32 or 64 gigabytes of memory, which in modern realities fills up very quickly. System files, messenger updates and social media cache occupy the lion’s share of available space, leaving the user with a minimum of space for personal data.

Fortunately, the device supports the installation of microSD cards up to 256 GB. This allows you to significantly expand the capabilities of the gadget, but the standard installation does not always allow you to immediately transfer programs there.

In this article, we will discuss in detail the process of turning a regular flash drive into a full-fledged analogue of internal memory. You will learn about the risks, equipment preparation and step-by-step algorithm of actions that will help free precious megabytes on the built-in drive of your smartphone.

Preparation of a memory card and necessary tools

Before you start any manipulation of the file system, you need to make sure the quality of the drive used. Write and read speed directly affects the speed of installed applications. Cheap Class 4 or Class 6 cards can cause severe delays and "hangs" of the interface.

UHS-I cards with a Class 10 or higher are recommended, and models from proven brands such as Samsung, SanDisk or Kingston are the best choice. Low read speeds will cause heavy games and navigators to load significantly longer than usual.

💡

Use only high-quality memory cards from well-known manufacturers, as cheap analogues often fail after formatting for internal memory.

It is important to keep all the data on the map, because during the setup process it will be completely formatted. All photos, music and documents will be permanently deleted.

Activation of Developer Mode for Advanced Settings

In some versions of the MIUI shell, the standard menu may hide forced port options. To access hidden features, you need to activate developer mode. This is a secure procedure that opens up access to deep Android settings.

• ✅ A pop-up notice will appear that you have become a developer.

After that, a new Developers item will appear in the main settings menu, in the Additional section, and this is where the tools for debugging USB and managing processes that may be needed in complex data transfer cases are located.

Formatting a card as an internal drive

This is a key step in enabling the system to recognize SD-The map is not an external storage for the photo, but an extension of the system disk. Without this step, porting most applications will be impossible or limited.

Plug the card into the slot and wait for notifications about the new device. Click on it or go to Settings → Storage. Select your memory card from the list of available devices. In the drive management menu, you need to select the option Format, and then Format as internal storage.

⚠️ Warning: Once formatted, the card will be encrypted and tied to that particular smartphone, and you can't just insert it into another phone or computer to read data without re-formatting.

The system will warn you of low drive speed if the card does not meet high standards, and you can ignore this warning if you are willing to tolerate the possible loss of performance in heavy tasks, the process will take several minutes during which the phone cannot be turned off.

Step-by-step instructions for transferring applications

Once formatted successfully, the system will automatically begin to redistribute resources, but for some programs, this process must be manually started, which allows you to control which programs will occupy space on the flash card.

Algorithm for transferring a specific program:

1. Go to Settings → Applications → All applications.
2. Find the program you want (such as a game or social network).
3. Slip by name to open the control menu.
4. Press the Warehouse or Memory button.
5. If transfer is possible, the Change or Move button will be active.

Select a point. SD-The system will move the application files and its data, the operation time depends on the size of the program and the speed of your memory card.

Setup the camera and save media files

Freeing up space for apps isn't the only goal. Photos and videos take up a huge amount. By default, the Redmi 7 camera saves the images into internal memory, ignoring the free space on the camera. SD-map.

To change this behavior, open the Camera app. Click on the menu icon (three bars) in the top right corner and select Settings. Find the Save to the Settings to the Switch. SD-Now all new images and videos will be automatically recorded on an external drive.

It is also worth checking the settings of messengers, in Telegram and WhatsApp, you can manually specify the path to save media files, which will prevent the system partition from quickly filling with a cache of correspondence.

Possible problems and ways to solve them

Errors can occur during operation, most often due to file system incompatibility or damage to sectors on the map. If applications start to work unstable or disappear from the menu, check the state of the drive.

Symptoms of problems may be as follows:

• 📉 Strong slowdown of the interface when starting programs from the map.
• ❌ Errors when opening files or message "File is corrupted».
• 🔄 Infinite download or cyclical restart of the application.

⚠️ Note: If the memory card is physically removed from the device, all applications transferred to it will stop working and will be marked by the system as remote.

You can use Android's built-in tools to diagnose it. Go to Settings → Storage and check the status of the card. If the system suggests formatting it again, then the file system is corrupted, in which case only full formatting with loss of data will help.

💡

The stability of the ported applications depends on the speed class of the memory card; savings on the drive will lead to constant lags.
