Owners of the Xiaomi Redmi 8 Pro smartphone often face the need to expand the device’s internal storage, especially if the amount of internal memory is exhausted by photos, videos and apps. The question of where the storage slot is physically located becomes critical when the phone is full and the system insists on clearing the place. Unlike some modern flagships, devoid of connectors, this model retains a useful expansion feature.
Many users mistakenly search for a separate compartment on the case, unaware that modern gadgets use a combined tray. Finding a memory card in this case involves finding a special retractable mechanism hidden in the end of the case. Wrong actions when trying to remove the tray can lead to damage to the body or mechanical failure of the holder, so it is important to clearly understand the design of the device.
In this article, we will take a closer look at the anatomy of the Redmi 8 Pro, explain how to remove the tray correctly, what type of cards are supported and what to do if the device does not see the new drive. You will learn about the nuances of formatting and the features of the MIUI shell with external media.
⚠️ Attention: Before any manipulation of the expansion slot, we strongly advise you to turn off the smartphone to eliminate the risk of short circuit or software errors when reading data.
Location of the slot for memory cards on the body
Physically slot for memory card in the Redmi model 8 The Pro doesn't have a separate hole. Xiaomi engineers, like many other manufacturers, have implemented a hybrid tray format "2-into-1". This means that the same compartment is intended for either two SIM-card or for one SIM-This is a microSD card and one microSD card, and it's on the bottom end of the device, to the left of the charging connector. USB Type-C, if you look at the screen.
To detect the hidden mechanism, look carefully at the bottom of the phone, and you'll see an elongated frame recessed into the body, with a small circular hole on one side, and this is the opening that is the point of access to the insides of the tray. It's important to understand that trying to frame the frame with your nails or sharp objects without first using the key can lead to chipped plastic or damage to moisture seals.
The tray is designed to have two sides, one side features a nano-SIM platform and the other a microSD pin. The Xiaomi Redmi 8 Pro supports memory cards up to 256GB (officially) and up to 512GB (unofficially but verified by users), a substantial amount that allows you to turn a budget smartphone into a multimedia center.
- 📍 The slot is located on the lower end of the body, next to the charging port.
- 🔌 Hybrid tray format is used (SIM + SIM or SIM + microSD).
- 📏 Supports microSD, microSDHC and microSDXC cards.
- 🚫 Separate second slot without retrieval SIM-card not provided.
And if you look closely, you can see that the tray frame is shaped to fit the contours of the body, and this is done to keep the device tight and aesthetic, and you don't have to try to remove the tray from the top or the side, because there are only volume control buttons and the power button.
Instructions for the removal and installation of the storage device
The process of installing an external drive requires accuracy and the presence of a special tool. Usually a metal clip comes with a phone, but if it is lost, a thin needle or a special key will fit. SIM-The main requirement for the tool is that it must be thin enough to enter the hole, and strong enough to withstand pressure.
☑️ Pre-installing check
First, take the tool and insert it perpendicularly into the round hole on the tray. Press until you have a characteristic click or feel a stop. The tray should extend a few millimeters, then you can gently pull it with your fingers. Don't put too much effort: if the tray doesn't come out, you may have inserted the key at a wrong angle.
After you remove the tray, notice the markings on it. One of the sites usually shows a memory card symbol or indicates "MicroSD." Put the memory card down with contacts (the contacts should look in the same direction as the contacts on the tray), keeping an orientation according to the shape of the cutout. The card should lie tight, without staggering, then gently insert the tray back into the phone to the end, making sure not to turn it over.
⚠️ Warning: Make sure the memory card is inserted into the tray before clicking and does not protrude beyond the edge of the frame, otherwise it can damage the contacts inside the phone when closing.
Once the device is turned on, the system must automatically determine the new drive. USB-If you don't, check the installation correctly by turning the map over or rubbing the contacts with soft cloth.
Setup and formatting in the Android system
After physical installation, Xiaomi Redmi 8 Pro should recognize the drive. However, to work properly, formatting is often required. Android offers two main modes of working with external media: as portable storage and as internal memory. The first option allows you to store photos, videos and music that can be transferred to other devices. The second option integrates the card into the system, allowing you to install applications on it, but makes the card unreadable on other phones without special reset.
To set up a card, go to Settings → About Phone → Storage. Here you will see a list of connected media. Click on your memory card name. If the card is new or previously used on another device, the system will prompt it to be formatted. This process will delete all data, so back up important files on your computer in advance.
What is the difference between FAT32 and exFAT?
The formatting process takes anywhere from a few seconds to a couple of minutes depending on the size of the card, and during this operation, a new file system is created that is optimized for the mobile operating system, and interruption of the process can damage the card, so it is better not to touch the phone at this time.
- 🛠 To set up, go to Settings → Warehouse.
- 💾 Select Portable Storage Mode for Media Files.
- 📱 The “Inner Memory” mode allows you to transfer applications.
- ⚡ Formatting is necessary for stable operation MIUI.
Once the setup is complete, a memory card icon may appear in the status bar, the device is now ready to record data, and it is recommended to immediately check the recording speed by taking several photos or recording a short video.
Transferring data and applications to a memory card
One of the main goals of installing an additional drive is to free up internal space. The MIUI shell installed on the Redmi 8 Pro has built-in tools for managing files, so you can manually transfer folders with photos, documents and music to the root folder of the map or create a new directory structure there.
Application portability is more complicated. Not all applications support external installation for security and performance reasons. If the application supports this feature, you will find the corresponding button in the Settings menu → Applications → (Select App) → Storage → Change. If the button is inactive or absent, the transfer is impossible without obtaining superuser rights (Root).
| Type of data | Can we move it? | Recommended method | nuance |
|---|---|---|---|
| Photos and videos | Yes. | Through the Gallery or the Files | Automatic recording is possible in camera settings |
| Music. | Yes. | Copying a folder | Player needs to be switched to a new folder |
| Annexes | Partially. | Through application settings | Depends on the software developer. |
| Documents | Yes. | Through the file manager | Convenient for working with office files |
💡
Configure the camera so that new pictures are saved immediately to the memory card. → item “Save on SD-map".
It’s also worth mentioning the ability to use the map to caching some system processes, although this feature is limited in modern versions of Android, the main advantage of which is the ability to store huge archives of correspondence in messengers if you redirect the way to save media files in the settings of the applications themselves, such as Telegram or WhatsApp.
Problems with card recognition and their solution
Sometimes users are faced with a situation where Xiaomi Redmi 8 Pro does not see the memory card, which can be caused by several reasons: from banal contamination of contacts to incompatibility of the file system. The first step should always be to reboot the device. If this does not help, try to remove the card and wipe the golden contacts with a wipe or an alcohol napkin.
A common problem is formatting the card in the NTFS file system, which is the default in Windows for large drives. Android out of the box can't read NTFS without third-party drivers. The solution is one - format the card to FAT32 or exFAT format using the computer or the phone itself. It's also worth checking whether the Lock switch is locked on the card adapter (if you use an SD adapter), although there is no such switch in the microSD, but it may be on the adapter.
⚠️ Warning: If the phone heats up in the lower end after installing the card, immediately remove the drive.This may indicate a short circuit or malfunction of the memory card itself.
In rare cases, the problem lies in a software firmware failure. Updating to the latest version through Settings → About Phone → Updating MIUI may contain fixes to the memory controller drivers. If nothing helps, it may be damaged tray or controller on the motherboard, which requires contacting the service center.
- 🔄 Perform a smartphone reboot.
- 🧹 Wipe the card and tray contacts.
- 💻 Format the map in FAT32/exFAT PC-only.
- 📲 Check the card on another device to rule out marriage.
Recommendations for the selection and operation of microSD
Choosing a smartphone memory card is not just about buying more volume. The Redmi 8 Pro needs read and write speed to run smoothly. The minimum speed class should be Class 10, but it’s better to target the UHS-I label (U1 or U3). These designations ensure that video is recorded without jerks and apps load quickly.
Avoid buying memory cards in markets or unverified stores where there is a high risk of buying a fake. Fake cards often show the wrong amount in the system, but when filled in, they begin to overwrite old data, leading to the irretrievable loss of photos and documents. Brands like SanDisk, Samsung, Kingston and Transcend have proven to be reliable partners for mobile devices.
💡
Buy memory cards only in official electronics stores and save the check - this is the only guarantee that the declared volume corresponds to the real one.
When you're in operation, try not to retrieve the card often. Each extraction cycle is a risk of contact oxidation or mechanical damage. If you often need to transfer data to your computer, use cloud services or use the same. USB-a cable to transfer files directly, leaving the card inside the phone, which will extend the life of both the drive and the smartphone connector.
