Owners of Xiaomi and Redmi smartphones often face a lack of built-in storage, especially if the device has a basic configuration of 32 or 64 GB. Android system, overgrown with cache, updates and new programs, begins to issue warnings about the lack of space, which significantly slows down the work of the gadget. Transferring data to an external drive is one of the most effective ways to free up precious space for stable operation of the operating system.
Unfortunately, modern versions of the shell MIUI HyperOS by default hides the ability to directly install programs on the SD-This is done for safety and speed, because external drives often have lower read and write speeds than internal flash memory. However, there are proven methods to circumvent these limitations, allowing you to use the memory card as a full-fledged extension of the system storage.
In this article we will discuss all the current methods of transfer: from standard system tools to advanced methods using the use of ADB-You will learn how to turn a regular flash drive into internal memory, which applications can be moved and which are better left on the built-in drive, and how to avoid data loss during the setup process.
Preparation of memory card and device for work
Before you start any manipulation of the file system, you need to make sure that the storage drive used is serviceable and compatible. The microSD card should be of high speed class, preferably Class 10, UHS-I or UHS-II, to minimize delays when running programs. Low read speed can lead to "freezes" of the interface and long loading of applications, which will negate all the benefits of expanding memory.
Insert the memory card into the slot of your Xiaomi or Redmi smartphone. If the device is already on, the system will notify you of the connection of a new media. In the window that appears, select the setting option. It is important to understand that the formatting process will destroy all the data on the card, so pre-copy photos and documents to your computer or to the cloud storage.
For some operations, you may need access to advanced settings. Make sure you have USB debugging enabled if you plan to use computer methods. Also check your battery power: it should be at least 50-60% so that a sudden shutdown does not damage the file system at a critical moment.
⚠️ Note: Formatting a memory card as an internal storage device encrypts it, and then the card will not be read on other devices or computers without first resetting and losing data.
☑️ Pre-testing
Standard method of transfer through Android settings
Start with the simplest and most secure way the operating system itself offers: Some versions of MIUI and certain Redmi models offer portability out of the box without the need for third-party software. Go to the settings menu and find the storage section.
Navigating the menu can vary slightly depending on the firmware version. Usually, the path is: Settings → Memory or Settings → About Phone → Storage. Here you will see a list of all the apps installed and the space they occupy. Select the program you want to move.
If the system allows for transfer, you will see the button "Move to the port". SD-Click on it and wait for the process to be completed, but it is worth noting that for many system applications and heavy games, this option may be inactive (shadowed), as developers prohibit the transfer of their products to external media.
- 📱 Open Settings and go to the Application section.
- 💾 Select Application Management to view the full list.
- 🔍 Find the right program and click on its name.
- 🔄 If available, click the “Move” button or change the memory type.
If the transfer button is inactive, this means that the application does not support the external drive at the software level, in such a situation, the standard methods will not solve the problem, and you will have to resort to more complex solutions described below.
💡
Not all applications can be migrated by the standard method, and system components and widgets often block this feature for system stability.
Adoptable Storage (Inner Memory)
The most effective solution for Xiaomi owners is Adoptable Storage, which allows you to format the memory card so that the system will consider it part of the internal storage, which allows you to install any application on it, even those that are not normally portable.
Activating this feature on modern versions of Android and MIUI often requires logging into developer mode or using special commands. First, make sure the card is inserted correctly. Then select the "Use as internal storage" option from the drive usage type selection menu (if it appears when inserted).
If the standard menu doesn't offer this option, the system can hide this possibility, in which case you need to activate the hidden menu through a computer or special application launchers that can cause system activity, and after formatting, the card will be encrypted and tied specifically to this smartphone.
| Type of storage | Speed of operation | PC-compatibility | Security of data |
|---|---|---|---|
| Internal (Internal) | Tall. | No (format required) | High (encryption) |
| Portable (portable) | Medium/Low | Yeah (like a flash drive) | Medium |
| Hybrid | Depends on the card. | Partial | Medium |
Once the card is in internal memory mode, the system may suggest moving the data you have already installed, agree to this action to immediately free up space, and now, when installing new programs, Android will default to offering the memory card as the primary storage location.
Why is the card not determined after transferring to another phone?
Advanced methods via ADB and command line
If the smartphone interface does not allow you to activate the internal memory mode, the tool comes to the rescue. ADB (Android Debug Bridge: This method requires connecting your phone to your computer via a computer. USB-It allows you to force support for expandable memory.
To start, you need to enable USB debugging in the Developer menu. To activate this item, go to Settings → About Phone and quickly click on the MIUI build number seven times. Once you have become a developer, go back to the settings menu and find the "Additional" or "Extended settings" section.
Connect your smartphone to your PC and open the command line in the folder with the ADB tools. Enter a command to check the connection:
adb devicesYou'll see a request for debugging permission on your phone screen, confirm it. Then you'll type a command to turn on internal memory:
adb shell sm set-force-adoptable trueOnce you have completed the command, restart your smartphone. When you reconnect the card or store menu, you should be able to format it as internal memory, which works on most Redmi Note and Xiaomi Mi devices.
- 💻 Install the drivers. ADB and Fastboot on the computer.
- 📲 Put the debugging on. USB developer-menu.
- 🔄 Reboot the device and format the map through the settings.
⚠️ Attention: Use ADB-Introducing incorrect commands can lead to unstable operation of the system or loss of data.
Transfer of multimedia and application cache
Even if you can’t move the body of an app, you can often move its heavy files. Many programs, such as instant messengers (Telegram, WhatsApp), navigators (Yandex Maps, Google Maps), and streaming services (Spotify, Netflix), allow you to choose the path to save cache and downloaded files.
Telegram's setup is a great illustration. Go to Settings → Data and Memory → File Path. You can specify the memory card as your primary storage, and that will free up gigabytes of space, because media files take up the lion's share of the messenger's memory.
Do the same with the camera and the voice recorder. Open the camera app, go to the settings and find "Save to the camera" SD-Activate it. All new photos and videos will be automatically recorded to an external drive, bypassing internal memory.
For navigation apps that download offline maps, also look for storage settings. On Google Maps, you can do this through the Offline Maps menu" → "Settings" → "Storage of the device. Choose yours SD-This is especially true for maps of large cities or entire countries.
💡
Cache and media transfer is often more effective than the transfer of the application itself, as content takes up 80-90% of the space.
Possible problems and ways to solve them
There can be specific problems when you use a smartphone with applications on the memory card, and one of the most common is when the device slows down, which happens when the memory card reads slower than the built-in module, the system constantly accesses the disk, and the narrow neck speed slows down all processes.
Another common problem is the disappearance of widgets or the failure of displaced applications after a reboot, which is due to the fact that the external map is mounted by the system a little later than the start of some services, in which case the application may not find its files and give an error.
If you notice that your phone is slowing down or apps are crashing, try retrieving the card and checking the system without it. If the problems are gone, the memory card is not coping with the load or has file system errors, in which case it is recommended to replace the drive with a faster one.
- 🐌 Low speed: Replace the card with a model marked A1 or A2, application-based.
- ❌ Reading errors: Check the card for errors through the computer or reformat it.
- 🔋 Battery discharge: Active operation with SD-The card can increase energy consumption.
It’s also worth remembering that when you reset your phone to a factory setting (Hard Reset), all data on the card, if it was formatted as internal memory, will be irretrievably lost along with your system settings. Always have an up-to-date backup of important documents and photos in the cloud.
