Changing carriers or transferring stored photos to a computer often poses a simple but technically important question for Xiaomi smartphone owner: how to get a memory card out of a device? In an era when mobile devices are getting thinner and moisture and dust protection is the standard, manufacturers are implementing various mechanisms for retrieving media. Mistakes can lead to tray damage, pin breakage or even file system software errors, so it is important to understand the physical design of your Redmi or POCO model.
Many users experience panic when they can’t find a slot or are afraid to damage a fragile mechanism. The Chinese giant’s modern line of smartphones offers several layout options, from classic retractable trays to hidden slots under the back cover. Safe extraction begins not with finding a needle, but with understanding what type of design is installed in your gadget and software preparing the device for this procedure.
In this guide, we’ll take a closer look at all the possible scenarios you might encounter.We’ll look at standard trays, combined slots, and the rare cases of a memory card hiding under the battery.Attention to detail at each step will help you avoid common mistakes and keep the integrity of both the memory card and the smartphone itself.
Pre-extraction programming
Before you take a paper clip or key to SIM-The critical step is to turn off the memory card software, and if you just pull the media out while the system is running, it can cause file damage, data loss, or even logical errors in the Android file system. The operating system must complete all read and write processes so that the data is not corrupted.
To do this, go to your device's settings. Find the storage section that's in the shell. MIUI HyperOS is usually called About the Phone. → Storage or Settings → The phone. → Memory. In this menu, you'll see a list of connected media that will list yours. SD-Click on it to reveal additional control options.
In the menu that opens, select the option to Disable or Remove SD-The system will issue a warning that applications using the card may stop working. Confirm the action. After that, the system will stop all background processes associated with the external drive and notify you that the card can be safely removed physically. Ignoring this step when using the card actively (for example, when recording a video or installing applications) can lead to data loss.
If you plan to extract SIM-The card, the software shutdown is not usually required, because the network will shut down automatically when it is retrieved. SIM-card, make sure this process is complete so you don’t lose your phone numbers.
💡
Before removing the memory card, close all applications that can use files from an external drive: gallery, voice recorder, video player and file manager.
Slot search and design type determination
The next step is to visually inspect the body of the smartphone, in the vast majority of modern models Xiaomi, Redmi and other devices. POCO memory card slot combined with slot for SIM-It's on one side of the device, usually the bottom or the top, and less often the left or right side, depending on the orientation of the screen.
Look carefully at the ends of the phone. You need to find a narrow hole next to the rectangular or oval contour of the tray. In some models, such as the Redmi Note series or Xiaomi Mi, the tray can be combined (SIM + SIM + MicroSD) or hybrid (SIM + MicroSD instead of the second SIM). It is important not to confuse the hole for extracting the tray with the noise reduction microphone, which is also a small hole, but does not have a plastic or metal tray frame around it.
There are also models with a non-removable back cover, where the memory card slot is underneath it, which is typical for some budget devices or specific protected models. In such cases, the extraction procedure requires removing the back panel, which often involves using a suction cup and heating the edges of the case, which is not recommended without experience, so as not to damage the moisture protection glue.
Tools: how to open the tray safely
To extract the tray, you'll need a special tool. With each new Xiaomi smartphone, a metal key clip is provided for this purpose. It has the optimal thickness and shape to activate the spring-loaded lock mechanism without damaging the internal components.
If the original key is lost, you can use a paper clip to straighten one of the ends of the paper clip, but be careful: the steel of the paper clips can be too soft and bend inside the hole, or, conversely, too sharp and scratch the body. It is strongly recommended not to use sewing needles, as they are too thin and can break inside the mechanism, stuck there forever. Also avoid using knives or pins that can damage the electronics in case of accidental slipping.
In emergency cases, if there is nothing suitable at hand, you can use a thin part of the carnation earring or a special pin for the purpose of the carnation. SIM-The main requirement for the tool is that it must be strong enough to press, and have a diameter corresponding to the hole (usually about the edge of the hole). 1-1.5 mm).
☑️ Tool preparation
Step-by-step: extraction of the combined tray
The process of removing the tray requires precision and the right angle of inclination of the tool. Take the smartphone in one hand and the tool in the other. Insert the sharp end of the clip or key into the hole perpendicular to the edge of the case. You do not need to insert the tool at an angle or into adjacent holes (microphones).
Press the instrument with moderate force until a characteristic click. You will feel the spring work and the tray will move out of the body a little. Don't try to push too hard if the tray doesn't come out - you may not have hit the lock mechanism. After clicking, gently pull the tray out with your fingers.
When the tray is removed, notice the labeling, and it's usually engraved with symbols that tell you where to put it. SIM-The card, and where to - the memory card MicroSD. In combined trays, the memory card is often located on top of the memory card. SIM-Carefully place the card with your nail or a plastic spatula and remove it.
When you reassemble, make sure you insert it with the same side that you removed. Forced push of the tray can cause the guides inside the housing to break.
What to do if the tray is stuck?
Specificity of extraction in models without tray (under the battery)
Some budget models or older-series devices (such as some versions of the Redmi Go or Redmi 9A in certain regions) may have a memory card slot located directly in the case under the back cover.
To access the memory card, these models need to find a small cutout (usually in the lower corner on the back) that allows you to fit the lid with a nail or a special spatula. Carefully pull this cutout to snap the locks around the perimeter. Do not use sharp metal objects so as not to damage the plastic of the case.
Once the lid is removed, you'll be able to access the battery. In some cases, the memory card can be removed without removing the battery unless it blocks access to the slot. If the battery closes the slot, it needs to be carefully removed by pulling a special tongue or pulling a finger at the edge. The memory card in these models is usually inserted before the click, so you need to press it slightly in order to release the lock, and then pull it out.
Careful: In removable battery models, the battery and memory card slot contacts are open. Avoid touching metal contacts with your fingers or metal objects so as not to cause static electricity or short circuit.
Compatibility table and card types for Xiaomi
When working with memory cards, it is important to know what types of media your model supports. Using unsupported cards can lead to unstable system operation or inability to read data. Below is a table that helps determine the type of card and its characteristics.
| Type of card | Maximum volume | Compatibility | Speed (class) |
|---|---|---|---|
| MicroSD | 32GB | All Xiaomi models | Class 2-4 |
| MicroSDHC | 64GB | Devices after 2015. | Class 6-10 |
| MicroSDXC | up to 1 TB | Modern smartphones (Android 6+) | UHS-I / UHS-II |
| MicroSDXC UHS-II | 2 TB | Xiaomi Flagships (Not Guaranteed Support) | V60 / V90 |
Note that even if the phone physically accepts a large card (for example, 512 GB or 1 TB), software it may not recognize it if the model specifications claim support only up to 256 GB. Always check the official specifications of your device on the manufacturer's website.
Possible problems and ways to solve them
There can be a variety of difficulties in retrieving or reusing the card, and one of the most common problems is that the phone stops seeing the memory card after re-installing it, which can be due to oxidation of the contacts, wipe the gold contacts of the card with a soft dry cloth or a swallow, removing any contamination.
Another common situation is that the memory card gets stuck in the tray, which happens if the tray is deformed or the card is not fully inserted. Don't shake the phone sharply. Try to gently push the card back to the click and retrieve it. If the card is stuck deep inside the phone slot, don't try to get it with tweezers or needles, there is a high risk of damaging the contact petals inside the smartphone.
⚠️ Warning: Never remove a memory card if the notification indicator flashes or if you see a message "Save data is in progress" This can lead to irreversible loss of photos and documents.
If the card is undetectable after retrieving and re-installation, try restarting the device. Sometimes the system requires re-initializing the drivers to recognize the external drive. Also check the card on another device (for example, on a computer through a card reader) to rule out physical malfunction.
💡
If the memory card is not readable after being removed, wipe the contacts first and check it on another device before making conclusions about the phone slot breaking.
Rules of storage and care of memory cards
Once you've managed to get a memory card out of Xiaomi, it's important to store it properly, unless you plan to use it again right away. MicroSD cards are sensitive electronic devices that are afraid of static electricity, moisture, extreme temperatures and physical strains.
Store the retrieved cards in special plastic cases where they were sold. If the original case is lost, you can use a small bag with antistatic coating or just a clean paper envelope. Don't leave the memory card just on a desk or in your pocket, where it can bend or lose contacts due to dust and pile.
Regularly back up data from memory card to computer or to cloud storage. Flash memory, especially when used actively in smartphones (constant cache recording, photos, video), has a limited resource of overwriting cycles. Sudden card failure is not uncommon, and having a copy of the data will save you from losing important memories.
⚠️ Warning: Avoid storing memory cards near sources of strong magnetic fields (speakers, magnets on covers) and in places with high temperatures (in direct sunlight in the car), this reduces their lifespan.
