Removing a microSD card from a Xiaomi smartphone seems like a simple procedure, but wrong actions can lead to data loss, slot damage or even device failure. SIM-In this article, we will discuss all the nuances, from the preparation of the device to the physical extraction of the map, including the features of the different versions. MIUI popular Redmi models, POCO mi.
It is important to note that the process differs depending on whether the card is used as a portable storage or as internal memory (Adoptable Storage in Android). In the first case, the extraction will be quick, in the second case, you will need preliminary preparation, and we will also consider the typical mistakes that users make, and give recommendations for the care of the memory card slot.
Preparing the smartphone before extraction SD-map
Before you physically remove the memory card, you need to properly prepare the device, which will prevent file system damage and data loss. Start by checking the current status of the card in the settings:
- Open the Settings menu β Warehouse.
- Find the section SD-map or external storage.
- Check if the card is used as internal memory (to be marked as "Formatted as internal storage").
If the card is used as a portable storage device, it can be removed immediately after the card is disabled, but if it is integrated into the system as internal memory, it will require pre-mounting, otherwise Android can block access to files or even damage them.
Pay particular attention to applications that can work with the card in the background. For example, if you use a card to store music in Spotify or Google Maps cache, close these programs before extracting. Otherwise, they may crash after re-connecting the card.
β οΈ Note: If the memory card has been formatted as internal storage, removing it without first unmounting may result in the loss of all data on the device, including installed applications and their settings!
Step-by-step: how to safely disable SD-map MIUI
The process of software disabling the card depends on the version of MIUI and the smartphone model. Below is a universal instruction, suitable for most Xiaomi, Redmi and POCO devices:
- Open the storage settings: Go to Settings β Storage (or Settings β Additional β Storage in older versions of MIUI).
- Choose. SD-map: Slip on the item SD-map or external storage.
- Click "Disable" or "Extract": In the upper right corner, the button "Disable" (or Extract in new versions) will appear). β οΈ Warning: If the Disable button is inactive, the card is being used by the system. Close all applications that work with it, or restart the device.
- Confirm action: The system will warn you of possible consequences. Press OK or turn off.
After successful shutdown, a notification will appear SD-The map is disabled. It's safe to extract. Only now you can start physically extracting. If you skip this step, you risk damaging the file system of the map, which will lead to the need to format it.

Physical extraction of the card: features of different Xiaomi models
The design of the slot for memory cards in Xiaomi smartphones varies depending on the model. Consider the main types of slots and the nuances of their opening:
| Slot type | Xiaomi models | Features of extraction | Tool. |
|---|---|---|---|
| Hybrid Slot (SIM + MicroSD) | Redmi Note 10/11, POCO X3/X4, Mi 11 Lite | The tray is pushed out using a paper clip, the memory card is installed instead of the second SIM or on top of it (depending on the model). | Paperclip or special key |
| Dedicated microSD slot | Redmi 9/9A, POCO M3/M4, Mi A3 | The card is inserted separately from SIM. The tray can be combined with SIM-tray. | Paperclip or fingers (if the tray is semi-automatic) |
| Non-removable slot (under the battery) | Xiaomi Mi 5/6, old models | It requires disassembling the device, and the card is installed under the back cover next to the battery. | Plastic spatula, screwdriver. |
| Semi-automatic tray | Redmi K40/K50, POCO F3/F4 | The tray is pushed out with a light press, without a paper clip, and the map is fixed with a latch. | No (moving finger) |
For most modern Xiaomi models, the extraction process looks like this:
- Turn off your smartphone (recommended, but not necessarily for newer models).
- Find a hole to extract the tray on the side of the device.
- Insert a paper clip or special key into the hole before clicking.
- Carefully pull out the tray, remove the microSD card and insert the tray back in.
If the tray is not extended, do not put too much effort β this can break the mechanism. Try to slightly sway the paper clip in the hole or use a thinner tool. In some models (for example, the POCO X3 Pro), the tray can jam due to dust, in which case the purging of compressed air will help.

If there is no paper clip at hand, you can use an unbended stationery brace or even a toothpick (carefully not to break!). In extreme cases, a thin needle will do, but you need to act extremely carefully so as not to damage the slot O-ring.
What to do if Xiaomi doesnβt see it SD-post-extract
Sometimes, after re-installing the memory card, the smartphone will not recognize it, which can be due to several reasons:
- π File system damage β if the card is not properly disabled, Android may not recognize its structure.
- π Insufficient contact β dust or contamination of the card or slot contacts.
- π οΈ Software failure MIUI β Rarely, but errors occur in the operation of storage drivers.
- πΎ Incompatibility of formats β the map is formatted in NTFS or exFAT, and the device supports only FAT32.
To diagnose the problem, follow the following steps:
- Check the card on another device: Put it in your computer or other smartphone. If the card is not read everywhere, the problem is that card itself.
- Clear the contacts: Wipe the card and slot contacts in your smartphone with soft cloth soaked in alcohol. Don't use abrasive materials!
- Reboot the device: Sometimes a simple reboot helps, especially if the card is determined by the system but not mounted.
- Format the map: If the data is not critical, format the map into FAT32 via computer or in Xiaomi settings (Settings) β Warehouse β SD-map β Format).
If the card is still not recognized, try upgrading the MIUI firmware to the latest version β new updates often fix external drive errors, and in extreme cases, you may need to reset to factory settings, but this is an extreme measure.

Common Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when working with the Internet. SD-These are the most common ones and ways to prevent them:
- π« Removing the card without disabling the settings is the main cause of file damage. Always use the Disabling function. MIUI.
- π Use of non-original adapters β cheap card readers can damage the contacts of the card or slot.
- π¦ Getting moisture into the slot - even a slight humidity can cause contacts to corrosion. avoid using your smartphone in damp rooms.
- β‘ Formatting the map in NTFS β Xiaomi (like most Android devices) does not support this file system for removable drives.
- π Frequent memory card change: the slot mechanism is designed for a limited number of retrieval cycles.
Critical error: Using a memory card as internal storage on Xiaomi budget models (e.g. Redmi) 9A or POCO M3). These devices have weak memory controllers, and integration SD-Cards in the system can lead to slowdown and frequent failures.It is recommended to use the card only as a portable storage.
Another common problem is that you freeze when you turn off the card, which happens when you have apps installed on it or you have a cache of active processes on it, and the solution is simple: close all the programs before you turn off and restart the device. If the smartphone still freezes, try turning off the card in safe mode (press the power button β Safe Mode).
Care for a memory card slot: tips for extending the service life
Slot for SD-The cards are one of the most vulnerable parts of Xiaomiβs smartphone, and a breakdown often results in costly repairs, requiring the replacement of the entire mother module:
- π§Ή Regular cleaning: Once in a while 2-3 For a month, blow the slot with compressed air (for example, a canister for cleaning equipment), this will remove dust and small debris.
- π‘οΈ Moisture protection: Avoid using your smartphone in the rain or in high humidity. If the card is wet, dry it in rice or silica gel for at least 12 hours.
- π Proper extraction: Don't pull the tray out suddenly, it can damage the spring mechanism. Move the paperclip smoothly, without jerking.
- π± Use of covers: Dust-protected covers (such as rubber plugs) significantly reduce the risk of dirt entering the slot.
If you notice that the tray is stiff or the map is not fixed well, this is the first sign of wear and tear.
- Try to clean the slot with a cotton swab dipped in isopropyl alcohol.
- If the problem persists, contact the service center, and self-repairing can make things worse.
For non-removable slot models (such as the Xiaomi Mi 6), care is even more important β if dust hits the back cover, cleaning it will require a complete disassembly of the device. If you change memory cards often, consider using a USB-C β microSD adapter instead of an integrated slot.
Features of working with SD-maps in different versions MIUI
The functionality of external drives in MIUI has changed from version to version.
| MIUI version | Features of working with SD-map | Limitations |
|---|---|---|
| MIUI 8-9 | Adoptable Storage Support: A separate menu for managing external drives. | Frequent failures when disabling a card formatted as internal storage. |
| MIUI 10-11 | Improved stability with exFAT. added the option of automatic mounting of the card when connected. | No NTFS support. Applications on the card run slower than in internal memory. |
| MIUI 12-13 | Optimized power consumption when working with cards, added protection against random formatting. | The Adoptable Storage function is hidden in the developer (For developers β Format as internal). |
| MIUI 14+ | Support for Android 13 and new SD Express standards, improved compatibility with large-volume cards (1 TB+). | On some models, the ability to use the card as internal memory is disabled. |
In MIUI 12 and later, the function of formatting the card as internal storage is hidden by default.
- Activate Developer Mode (7 times tap the MIUI version in Settings β About Phone).
- Go to Settings β Additional β For developers.
- Find the option to format as internal storage and turn it on.
If you use the card as internal memory, remember that many applications will stop working after it is removed, and it is also not recommended to use this feature on Class 4 or Class 6 cards, because their write speed is not enough for stable system operation.
