Modern smartphones Xiaomi, Redmi and Poco are often equipped with a hybrid slot or a separate compartment for microSD drives. Users face the need to remove the memory card when transferring files to a computer, replacing the drive with a larger one or if there are software errors reading. Wrong actions can damage contacts or even break the tray mechanism, so it is important to understand the physical construction of your device.
In this article, we will discuss all the nuances of the procedure, including working with models without a separate slot and methods for safely extracting stuck cards. You will learn how to programmatically turn off the drive before physical extraction to avoid data loss.
Before you start any manipulation of the hardware of the smartphone, you need to make sure that the device is not in the process of actively recording data, this can be the installation of applications, saving photos or the operation of the navigator. Ignoring this rule often leads to corruption of the file system, after which the card can be determined as empty or require formatting.
Pre-extraction programming
Physically removing the drive without first shutting down the system is a risk. Android operating system and the MIUI or HyperOS shell must complete all background processes. If you just take out the card while recording, the files may become unreadable, and the card itself can go into read-only mode to protect data.
For safe extraction, look for Settings on your desktop or app menu. Go to About Phone or Advanced Settings, which usually houses storage management. In some versions of firmware, the path looks like Settings → Memory. Here you need to find your card and click on "Disable" or "Secure Retrieval".
Once confirmed, the system will stop all processes, you will receive a notification that the drive can be removed, only after this message appears or the card icon disappears from the status bar, you can pick up a paper clip.
💡
Before extracting the card, close all applications that can use external storage: voice recorder, camera, file manager and music players.
It is important to note that if the card was used as internal memory (extension for installing applications), a simple extraction will cause the programs installed on it to fail, in which case it is better to transfer the data back or delete the applications before pulling out.
Slot design: hybrid and individual trays
Xiaomi devices fall into two main categories by type of SIM card installation and memory. Understanding the type of your slot is critical so as not to damage the mechanism. In older and budget models, you often find a combined version where the space for the second SIM card is occupied by a memory card.
In more modern flagships and devices of the middle segment, manufacturers often refuse to expand the slot at all, but in models with support for MicroSD there are two options:
- 📱 Separate slot: There are two independent holes at the end of the case. SIM, It's the most convenient option for changing the drive without removing the SIM card.
- 🔄 Hybrid slot (2-into-1): The tray has two sides or a special shape. SIM-card, on the other hand, microSD or the second card SIM It's a memory card, and it's important to not confuse orientation when you reverse-install it.
⚠️ Warning: Never try to insert a memory card into a slot SIM-The microSD is much smaller and can fall inside the case, requiring the smartphone to be disassembled to be removed.
You can determine the type of tray by looking carefully at the end of the device in good light, if there is one hole and there is no second one next to it, then you have a hybrid version. If there are two holes, check the model instructions or remove the tray to see the markings inside. Usually, inside the tray, a diagram showing where to insert something is drawn.
When working with hybrid trays, there is often confusion with the orientation of contacts. Gold pins of the card should always be directed down (to the board), unless otherwise indicated in the scheme on the tray. Incorrect installation can lead to short circuit contacts.
Step-by-step instruction: extraction with a clip
This is standard procedure for most smartphones. You'll need a special metal clip that comes with the kit, or a thin needle. Use of stationery clips is acceptable, but they can be too soft and bend, so it's better to use hardened steel.
☑️ Safe extraction algorithm
Find a hole on the bottom or top end of the body. Put the tool strictly perpendicular to the plane of the body. You don't have to push with all your strength, but the force must be sure. You have to feel the lightweight spring stop, and then click the mechanism.
Once you click, the tray will extend a few millimeters. Pull it carefully with your fingers. Don't use tools (tweezers, knives) to pull the tray, as you can scratch the frame or damage the contacts of the map. When you have the tray in your hands, just take the card out with your nail or plastic spatula.
If the tray is not taken out:
- 🔍 Check the angle: Make sure you press exactly into the center of the hole, not at an angle.
- 🛑 Don't overload: Excessive force can break the plastic holder inside the mechanism.
- 🔦 Inspect the hole: Inside there may be dust or pile that blocks the movement of the pin.
In rare cases, the tray can get stuck due to the deformation of the body after falling. If you are sure that you are pressing correctly, but the tray does not respond, try to slightly (literally a millimeter) press the tray with your finger, and then sharply press the paper clip, sometimes this helps to disrupt the stalled mechanism.
What to do if there is no separate slot or tray
Many new Xiaomi and Poco models lack a memory card slot. If you don't find a hole on the end, chances are your model doesn't physically support memory expansion, so you can't pull it out because it's not there, only the built-in drive.
However, if you know exactly what the card is inside (for example, the phone was bought with the card already installed, or it is a specific modification), and the tray is not, the options are as follows:
- Disassembly: In some rare cases, the card may be mounted under the back cover (if it is removable) or require the complete removal of the rear panel.
- Internal installation: There is a myth that you can insert a card inside the case without a tray. This is a gross mistake. The card must be fixed with a tray to ensure contact. If there is no tray, the card is not installed correctly.
⚠️ Warning: Do not try to disassemble the smartphone if it is under warranty. Self-opening the case will lead to loss of warranty obligations.
If you are faced with a situation where the tray is present, but it is not removed in the standard way (for example, the hole is clogged or the mechanism is broken), do not use glue. Attempting to glue the paper clip to the tray almost always ends with the glue entering the mechanism, after which the card will be extracted only in the service.

Removal problems: the map is stuck
The worst thing is when the tray is removed and the memory card is left inside the phone, often because of static electricity that sticks the card to the contacts, or because of mechanical snag of the spring.
Do not shake your phone violently or knock it on the table, the card may shift and block other important contacts or get stuck in an inaccessible place.
| Method | Description of action | Risk |
|---|---|---|
| Sticky ribbon | Stick a piece of tape sticky side to the edge of the card and pull | Low (unless you touch your contacts) |
| Tweezers | Carefully grab the edge of the map with thin tweezers | Medium (contacts can be damaged) |
| Blowing out | Use a pear to clean the optics | Low (but the map can fly far) |
| Double tray | Insert the empty tray to the end and sharply pull out | High (contacts inside may be damaged) |
The safest method is to use a thin tweezer with a non-metallic sponge or a plastic spatula. If the card is visible but not reached by your fingers, try to gently tweak the edge of the card. If the card is stuck deep and does not lend itself, it is better not to aggravate the situation.
💡
If the card is stuck inside and is not retrieved with tweezers or tape, stop trying. Further action may lead to a break in the reader, which will cost more than the memory card itself to repair.
Contact and maintenance
Once you've managed to pull out the card, it's recommended that you do preventive maintenance, and contact oxidation is a common cause of reading errors and sudden shutdowns, especially if you've been using your phone for more than a year.
Take a soft, lilac-free fabric (microfibre) and moisten it lightly with isopropyl alcohol. Wipe the golden contacts on the memory card itself. You need to move along the contacts, not across, so as not to damage the tracks. Let the alcohol completely evaporate before installation.
Also, look at the tray itself and the hole in the phone. There may be pocket dust that accumulates, which acts as an insulator or an abrasive, blow the hole with compressed air, or gently clean the hole with a dry soft brush. Don't use cotton swabs inside the deep hole - the pile can get stuck.
Regularly checking a memory card is important for data durability, and every six months it is recommended that:
- 💾 Backup important files to your computer or the cloud.
- ✅ Checking for errors through a computer (chkdsk team).
- 🔄 Format a map if a noticeable decrease in the recording speed.
