Modern Xiaomi smartphones often feature slots to expand internal memory, allowing users to store thousands of photos, high-resolution videos and heavy applications without fear of overflowing the drive. However, there comes a time when the drive needs to be replaced with a more capacious one, transfer data to a computer or simply check files through a card reader. At this point, the owner of the gadget is faced with the question of how to correctly and safely extract the memory card without damaging either the media or contacts inside the device.
The extraction procedure seems trivial, but Redmi and POCO smartphones often use combined trays where the SIM card space is combined with the microSD. Sloppy handling of the mechanism can lead to a jamming tray or even damage to the motherboard. That is why it is important to clearly understand the design of your particular device and follow the sequence of actions to avoid unpleasant surprises.
In this article, we will discuss in detail all the nuances of working with a memory slot in Xiaomi devices. We will examine the differences between the models with a side and lower tray location, discuss the software disable the card before extraction and give recommendations for the care of contacts. Remember that removing the card without first turning off the system can lead to loss of unsaved data or damage to the file system. Let’s figure out how to make this process as safe as possible for your gadget.
Preparation of the device for retrieval of the memory card
Before you can get a paper clip or a key to be retrieved, you have to do a series of preparatory steps at the software level, a critical step that many users ignore, which often leads to read errors or data loss. The smartphone must be turned on, but the files on the map must be stopped by the system.
Go to your device's settings and find the partition that's responsible for the storage. Depending on the version of the MIUI shell or HyperOS, the path may vary slightly, but the logic remains the same. You need to force the drive to be terminated so that the operating system stops writing or reading information.
- 📱 Go to the Settings menu and select About Phone.
- 💾 Find the Storage or Memory section in the list of available options.
- ⏹️ Click on the settings icon or three dots in the corner of the screen, then select Disable. SD-map.
- ✅ Wait for notification that the memory card is successfully disabled and safe to retrieve.
After performing these actions, the system blocks access to the file system of the card, which minimizes the risks of corruption (damage) of data. If you just pull the card while recording video or installing the application, the files can become unreadable.
Determination of the type of tray and slot location
Xiaomi devices have gone through many design changes over the years, and the location of the SIM card slot and memory is no exception. Understanding where the tray is in your model is the first step to successful recovery. Most modern flagships and mid-range models use a side location.
Carefully inspect the ends of your smartphone. If the tray is on the top or bottom edge, this usually indicates older models or specific protected versions. The side tray is usually located on the bottom end, left or right of the USB Type-C charging connector. In some models, such as the Xiaomi Mi Mix series, the tray can be hidden under the back cover, but this is rare for current devices.
It's also important to determine the type of tray, because it depends on how you place the card. There are two main options: combined and separate. In the combined version, the memory card takes the place of the second SIM card, and you can not use two SIMs and a memory card at the same time. In the separate version, the seats are independent. The design of the tray dictates the correct installation and extraction.
⚠️ Warning: Never try to force a tray into or out if it's not moving.Make sure you use the right side of the key and hit the mechanism hole.Excessive force can break the plastic gears inside the body.
For an accurate definition of your tray model, refer to the technical documentation or use the table below, which gives common configurations for popular smartphone series.
| Smartphone series | Location of the tray | Type of tray | Support for maps |
|---|---|---|---|
| Redmi Note (series 10-13) | Lower end (left) | Combined | 2 SIM or 1 SIM + microSD |
| Xiaomi Mi (series 11-14) | Lower end (left) | Separate (more often) | 2 SIM + microSD (not all) |
| POCO X/F series | Lower end | Combined | Hybrid slot |
| Redmi A Series | Lower end | Separate | 2 SIM + microSD |
Necessary tools for the job
Removing the tray overwhelmingly requires a special tool that comes bundled with the device, a small metal paper clip with a plastic handle, often referred to as the "SIM card key," and if the original tool is lost, it can be replaced with a stationery clip, straightening one of the ends, or a thin needle.
However, the use of improvised tools carries certain risks: a needle that is too thick may not enter the opening of the mechanism, and a needle that is too thin may bend and stuck inside. The ideal tool should be about 1-1.5 mm in diameter and be stiff enough to transfer force to the spring mechanism of the tray. A metal key is preferable to plastic counterparts that can break inside the housing.
You may also need a soft cloth or an antistatic mat to put your smartphone down during the procedure, which will protect the screen and back cover from scratches, and prevent the device from slipping off. Make sure your hands are dry and clean so you don't leave greasy marks on the card or tray contacts.
💡
If there is no special key at hand, use a thin sewing needle, but be careful not to prick your finger when pressed hard.
Step-by-step instructions for removing the tray
Once you've programmed the map to be disabled and the tool ready, you can begin to physically extract it, which requires precision and precision of movement, and take your time to avoid damaging fragile structures.
Find a small circular hole on the end of your smartphone next to the rectangular shape of the tray, and that's where you put the key in. Place your smartphone so that the screen looks down or up, but not towards your face, in case the tray pops out with force. Put the key point perpendicular to the surface of the case.
- 🔍 Find the hole of the ejection mechanism next to the slot.
- 🔩 Insert the key to the end, feeling a slight resistance of the spring.
- 💥 Press sharply but controlled until the tray is pushed out a few millimeters.
- 🤏 Carefully pull the tray with your fingers over the protruding edge until fully extracted.
Once you have the tray, take a close look at it. The microSD card is usually fixed in the recess by friction or a special pressing mechanism. In some Xiaomi models, the card is simply in the notch and you need to nail it. In others, you need to easily press the edge of the card to make it snap and jump.
If the card is not taken out easily, do not use metal objects to tamper with it. This can damage the contacts. Better sway the tray slightly or use a plastic spatula. After extraction, inspect the contacts of the card: they should be clean, without oxidation and scratches.

Features of the design of combined slots
Owners of budget and mid-budget smartphones Redmi and POCO often face so-called hybrid slots, in which the space for the second SIM card and the place under the memory card are physically combined, which means that you can use either two SIM cards, or one SIM card and a memory card.
The design of this tray requires special attention when installing and retrieving. The memory card and the SIM card are different sizes, and it is important not to confuse their seats. The Nano-SIM SIM is smaller than the microSD. If you try to shove the SIM card into the memory compartment or vice versa, the tray may not close completely or jam.
⚠️ Attention: In hybrid slots, the memory card is often held by the frame of the SIM card itself or by a special lock. When removing the tray, make sure that the card does not fall out inside the phone case, which happens when you move sharply.
When working with hybrid slots, it is important to remember the sequence. If you want to install a memory card, you will have to sacrifice a second SIM card. The extraction mechanism in such models is standard, but the tray can be more complex, with cutouts for different formats. Be careful when you install it back so as not to damage the contacts.

Care for memory card and contacts
Once you have managed to remove the card, it is recommended to carry out preventive cleaning, especially if the device is used in dusty conditions or is carried in a pocket without a cover. Dust and villi, getting into the tray, can disrupt the contact between the card and the smartphone reader, which will lead to read errors.
To clean the contacts of the card itself, use a soft, dry, lilac-free fabric. You can moisten it slightly with isopropyl alcohol, but only if you are sure that it will completely evaporate before installation. Never use water or aggressive solvents. The contacts should be shiny and have no visible contamination.
The slot itself in the phone also requires attention. Blow it with compressed air from a spray can or use a pear to clean the optics. Don't pick up metal objects inside the slot, as there are thin spring-loaded contacts that are easy to bend. Regular cleaning prolongs the life of the memory card and prevents system failures.
💡
Regularly cleaning the card and slot contacts prevents 80% of data reading and file system errors.
Frequent problems and their solution
Even if all instructions are followed, users may encounter difficulties, and one of the common problems is when the phone stops seeing the card after re-installing, which may be due to improper installation, contact oxidation, or logical system error.
If you can't find the map after you've removed it and re-installed it, try rebooting the device. If that doesn't work, check if the card is inserted properly in the tray. It should be tight, it should be non-skewed. Sometimes formatting the map on the computer helps, but that will delete all the data.
In rare cases, the problem is mechanical damage to the tray or the reader itself on the board. If the card doesn't work in any device, it probably malfunctioned. Memory cards have a limited resource of overwriting cycles and can stop functioning suddenly.
