Modern Xiaomi Redmi smartphones offer impressive specs, but internal storage often fills up faster than we expect. High-resolution photos, apps and instant messenger cache quickly eat up the available space, forcing the user to think about expansion. Fortunately, many models support external microSD drives, which allows you to increase the amount of memory by several times.
The process of installing a drive seems elementary, but careless actions can damage the tray or the card itself. In this article, we will discuss in detail how to properly remove the sim tray, determine its type and safely install the drive in your smartphone.
Before you start physical intervention, you need to make sure that your model does support memory expansion.Some budget versions of devices may have a hybrid slot where you install a second one. SIM-The card makes it impossible to use a flash drive at the same time.
Preparation and selection of a suitable storage device
The first step is to purchase a compatible memory card, and you should not buy the first solution, because the speed of the interface directly affects the speed of the system. For modern devices, the best choice is a UHS-I or UHS-II card with a speed class of at least 10.
Pay attention to the marking microSDHC or microSDXC. The first stands for drives up to 32 GB, the second - from 64 GB and above. Older models of phones may not see large-volume cards, so before buying it is worth checking the specifications of your gadget on the official website of the manufacturer.
⚠️ Warning: Buy memory cards only from trusted electronics stores.The market is overrun with fakes that can suddenly fail, resulting in the irretrievable loss of your personal data.
It is also important to consider the volume. If you plan to store only documents and music, 32-64 GB will suffice. For recording video in 4K or installing heavy games, it is better to consider options for 128 GB or 256 GB. Make sure that the card file system is formatted in FAT32 or exFAT, as these are the most compatible formats for Android.
Tools and Slot Search
To extract the tray, you'll need a special paper clip that comes with the device. If the original tool is lost, you can use a thin needle or paper clip that is straightened to the desired shape, the main requirement is a sharp and thin tip that can get into the micro hole.
Take a closer look at the body of your Xiaomi Redmi. SIM-It's usually on one side of the card or memory, left or right, and in some models it can be on the top or bottom end, although this is less common, and there's often a little icon next to the extraction hole that looks like a memory card or a memory card. SIM-map.
While modern operating systems support hot connection, a software failure during initialization of new hardware can lead to file system errors.
The process of extracting the tray and installing the map
Insert the tip of the clip into the tray hole strictly perpendicular to the body. You don't have to push too hard; press it confidently enough, but softly enough, so that the latch mechanism works, and the tray is pushed out a couple of millimeters, and then you can carefully remove it with your fingers.
Now you need to define the tray configuration. There are two main types:
- 📱 Separate slot: The memory card has its own place and does not interfere with the work SIM-map.
- 🔄 Hybrid slot: place under microSD and the second SIM-You can use either two SIMs, or one SIM and a flash drive.
Put the memory card in the space that it's supposed to have. Notice the shape of the cutout, which is the shape of the seat. If the card doesn't fall flat, don't push it. Turn the drive over or try to change orientation, because the wrong setup can damage the contacts.
☑️ Pre-installing check
Carefully insert the tray back into the case. It is important to observe the orientation: the bevel of the card angle should coincide with the bevel in the tray. Push the tray until you click or completely dive, but without undue effort. If the tray does not enter easily, check its position again.
Setup of the file system after installation
Once the smartphone is turned on, the system will automatically detect new hardware, a notification should appear on the screen that the memory card is recognized, however, to get full operation, additional settings are often required through the Settings menu.
Go to Settings → About Phone → Storage (the path may vary slightly depending on the version of MIUI or HyperOS). Here you will see information about occupied and vacant space. If the card is new, the system may suggest formatting it.
| Parameter | Description | Recommendation |
|---|---|---|
| Formatting | Erase all data and create a new structure | Definitely new cards |
| File system | Data organization (FAT32, exFAT) | exFAT for cards >32 GB |
| Use of the | Power storage mode | Portable storage |
| Reading speed | Speed of data acquisition from the map | Depends on the class of the card. |
When formatting, all the data on the media will be deleted. If there were files on the map, copy them to the computer in advance. The formatting process takes a few seconds, after which the drive is ready to write the information.
Using the card as an internal storage
Some versions of Xiaomi’s firmware have a feature that allows you to use the memory card as part of the phone’s internal memory, allowing you to install apps directly on the flash drive, freeing up most of the device’s storage.
To activate this feature, go to the storage settings, select your card and click "Use as internal storage." The system will warn that the card will be encrypted and cannot be read on other devices without re-authorizing.
Risks of using the card as internal memory
This method is ideal if you have a 32GB model that is critically lacking, but for cards less than 64GB and speeds below Class 10, it is better to use the standard portable storage mode for photo and media.
Data transfer and file management
After successful installation and setup, the question arises: how to transfer files? standard file manager Explorer (or File Manager) allows you to easily move data between internal memory and the card. Just select the desired folders (for example, DCIM, Download) and select the option “Move” or “copy”.
You can also set up automatic saving of new files to an external medium. In the camera settings, find the item "Save to the camera". SD-You can use the map and activate it. Similar settings are available in messengers like Telegram or WhatsApp in the section "Data and storage".
⚠️ Warning: Never remove a memory card while you are writing data or running applications.This can cause file spreadsheet damage and loss of information. Always use Safe Retrieval in your settings or turn off your phone.
Check the state of the drive regularly. If the phone is slowing down or files are no longer open, try re-formatting. Over time, the file system may become fragmented, which reduces access speed.
Possible problems and ways to solve them
Sometimes, a smartphone doesn't see a memory card. First, check the cleanliness of the contacts. Wipe them with a soft dry cloth or a swallow. Oxidation or dust can interfere with normal connection.
If the physical cleaning didn't work, try connecting the card through the card reader to the computer. If the PC can't see the drive, it probably broke. If the computer reads the card, the problem may be incompatibility of the file system or the volume.
💡
If the card is defined but is unstable, try formatting it on your computer by selecting the default cluster size and exFAT file system.
In rare cases, the problem lies in the software failure of the Android operating system itself. Rebooting the device in safe mode will help eliminate the influence of third-party applications. If this does not help, you may need to reset the phone to the factory settings.
💡
Most card recognition problems are solved by proper formatting in exFAT or replacing the drive itself with a higher quality one.
