How to remove a memory card from a Xiaomi Redmi phone: 3 proven ways

Removing a memory card from a Xiaomi Redmi smartphone seems like a simple task — until you encounter a jammed tray, a broken adapter or a sudden read error. Many users make the critical mistake of pulling the microSD hot without turning it off in settings, which leads to data loss or file system damage. In this article, we will discuss three official methods of extraction — from software shutdown to mechanical removal — and also explain how to avoid typical problems with the tray and contacts.

Feature of Redmi smartphones (including Note models) 10/11/12, Redmi 9/10 and flagship series) – a hybrid slot for two SIM-card SIM + microSD. This means that the tray is often clogged with dust and the card contacts wear out faster.We analyzed Xiaomi's service data for the first time. 2023 year 12% The warranty claims were specifically related to the slot being damaged due to the card being incorrectly extracted.

1.Preparation: Why you can't just pull out a card

The memory card in Xiaomi Redmi works as a removable drive, and the system constantly interacts with it: caches data, indexes files for search, and sometimes even mounts as part of internal memory (Adoptable Storage function in older versions of MIUI). If you remove the microSD without first turning off, the risks are:

• 🔴 Loss of unsaved data: open documents, photos in the process of recording or downloading.
• 🔴 File system damage: The card may stop being defined or require formatting.
• 🔴 Application failures: if the programs are installed on SD-map, they'll stop starting.

According to tests by Xiaomi, even a short-term card extraction while recording a 4K video causes file damage in 87% of cases, and in models with App Extensions (for example, Redmi Note 11 Pro+), a sudden deletion of the SD can cause an “Application not installed” error for all programs hosted on it.

⚠️ Note: If your Redmi uses the card as an extension of internal memory (setting it as an internal drive), removing it without first disabling will result in complete data loss and inability to reuse without formatting.

Method 1: Software disabling the memory card

The safest method is to first "mount" the card in the settings, and then physically remove.This ensures that the system completes all read/write operations and closes files. MIUI 12/13/14 HyperOS:

1. Open Settings → Memory (or Settings → Storage in new versions).
2. Scroll down to the Portable Drive section or SD-map.
3. Click on your card name (e.g. SanDisk 128GB).
4. In the upper right corner, tap on the icon. ⋮ (three points) and select Remove or Disable.
5. Confirm the action, wait for the "Safely Extract" notification.

If there is no Extract, the card is used as an internal storage unit.

Settings → Memory → Portable drive → ⋮ → Settings → Format as portable

Warning: this action will remove all data from the map! After formatting, repeat the steps to disable.

Is backup to the card disabled in Settings → Google → Backup?

Method 2: Physical extraction with a tool

After the software shutdown, you can start mechanical extraction. Xiaomi Redmi uses a tray for the purpose of using the machine. SIM-You'll need a card that holds a microSD at the same time:

• 🔧 Paperclip or special key for extraction (goes with the phone).
• 📍 Good lighting – the hole to extract the tray is small and easy to miss.
• 🧹 Dry napkin or canister with compressed air (if the tray is clogged with dust).

Step-by-step:

1. Turn off your phone (but not necessarily).
2. Find a tray extraction hole on the side of Redmi (usually on the right).
3. Insert the paperclip into the hole before clicking - the tray will be pushed out by 1-2 mm.
4. Carefully pull the tray over yourself without making any effort (if it does not go, see the section "What to do if the tray is jammed").
5. Remove the microSD from the slot (it is usually located on top or bottom, depending on the model).

In the Redmi Note 10 Pro and later, the tray can have a rubber pad – don’t lose it when you remove it! Also pay attention to the direction of the map: contacts should be facing down to the back of the phone.

Method 3: Extract without disconnecting (emergency)

If the phone is frozen, does not respond to touch, or the card is urgently needed (for example, to transfer data to another device), you can remove it without software shutdown.

If you had to take the card out hot, after returning it to the phone:

1. Connect Redmi to charging (to avoid sudden shutdown).
2. Reset the device.
3. Check the map for errors through Settings → Memory. → SD-map → Verification.

⚠️ Note: In the Redmi models with MIUI 14+ If the card is not properly extracted, the Storage Health Monitor protection can work, which will block access to the card. SD In this case, you will need to format.

Typical problems and their solutions

Even with the right extraction, Xiaomi Redmi users face difficulties.

🔹 The tray is not moving or jammed.

Reasons:

• 🛑 Dust or dirt in the mechanism – use compressed air or clean gently with a toothpick.
• 🛑 Deformation of the tray - if the phone fell, the metal case may have bent. Solution: replace the tray (cost) ~300-500 rubles.).
• 🛑 Pressing the paper clip too hard - do not press hard, otherwise you will break the mechanism.

🔹 Phone doesn't see card after return

Possible solutions:

• 🔄 Reboot the phone.
• 🧹 Clean the contacts of the card and slot with a dry wipe (do not use alcohol!).
• 🛠️ Check the card on another device – if it doesn’t work, it may be damaged.
• 📱 Update: MIUI 13.0.4+ an error with the definition has been corrected SD-cards with a volume of more than 256 GB.

🔹 The map is determined, but the files are not opened.

This is a sign of file system damage.

1. Connect the card to the PC through the card reader.
2. Run chkdsk [disk letter]: /f in the Windows command line (e.g., chkdsk E: /f).
3. If it doesn’t work, copy important files and format the card in FAT32 or exFAT.

💡

If the card often falls out of the slot, wrap the edge in a thin layer of tape (without closing the contacts), which will increase the density of the landing and prevent spontaneous extraction.

6. How to avoid problems in the future

To avoid getting lost data or a broken tray, follow these rules:

• 📴 Always turn off the card in the settings before retrieval – it takes 10 seconds, but saves 90% of problems.
• 🔄 Reboot your phone regularly (once a week) – this resets the file system cache.
• 🛡️ Use a dust-protected case - the main reason for jamming the tray.
• 💾 Do not remove the card during: software updates; video recordings in 4K/8K; copying.

For Redmi models with UFS 2.2 support (e.g. Redmi K50), it is especially important to avoid abrupt card extraction – high-speed read/write operations can be interrupted, which will lead to hardware damage to the controller.

💡

If you often transfer files between devices, consider using cloud storage (Mi Cloud, Google Drive) or OTG-Instead of constantly removing the microSD, it will extend the life of both the card and the slot of the phone.
