How to put a memory card in the phone Xiaomi Redmi 5A: instructions with nuances

Why You Need a Memory Card in Xiaomi Redmi 5A and What You Need to Know Before Installing

Smartphone Xiaomi Redmi 5A — One of the brand's most popular budget devices, but its built-in memory (16 or 32 GB depending on version) is quickly running out. High-resolution photos, apps and cache take up space, and a microSD memory card becomes a lifesaver. However, not everyone knows that in this model, the slot for the card is hybrid - it is combined with a tray for the second. SIM-So that means you have to choose between two. SIM, one SIM + microSD.

Before buying a card, check its compatibility. Redmi 5A supports microSD up to 256 GB (officially up to 128 GB, but users are successful in using large volumes). Speed class should be at least Class 10 or UHS-I for stable operation. Also note that formatting the card right on the phone erases all data - back up important files in advance.

If you have never opened the door for SIM-Be careful: Xiaomi uses fragile metal latches. If you unscrupulously extract it, you can bend contacts or break the mechanism. In this article, we will explain how to avoid errors and install the memory card correctly, and what to do if the phone does not see it.

Which memory card to choose for Xiaomi Redmi 5A: technical requirements

Not all microSDs are equally good for Redmi 5A. Cheap, nameless cards can slow, overheat, or not be detected by the system at all.

• 🔹 Volume: from 16 GB to 256 GB (optimally 64-128 GB for price and capacity balance).
• 🔹 Speed class: minimum class 10 or UHS-I (U1/U3) video-recording HD.
• 🔹 Brand: SanDisk, Samsung EVO, Kingston – reliable manufacturers with a guarantee.
• 🔹 Format: only FAT32 exFAT (NTFS unsupported!).

If you plan to shoot 1080p video or install heavy games, pick up an A1 or A2 card that is optimized for fast application experience, and Class 10 is good for regular photos and music.

Note: Redmi 5A does not support adoptable storage (Android card when the memory card becomes part of internal memory), the card will appear as a separate drive, and you can not transfer all applications to it – only part of the data (photo, video, music).

Step-by-step: how to insert a memory card in Xiaomi Redmi 5A

The installation process is simple, but requires care. Follow the instructions to avoid damaging the tray or contacts:

1. Turn off your phone. It's a must: a hot card change can cause the file system to crash.
2. Find a tray for SIM-It's on the left side of Redmi. 5A (near-volume).
3. Put a paper clip in the hole. Use a special key from the kit or an unbended stationery clip. Push until you click, the tray will move out.
4. Remove the tray. Pull it gently over yourself without making any effort.
5. Install a memory card. Put a microSD in the appropriate slot (usually signed or different in size) Contact down!
6. Put the tray back where it is. Make sure it sits smoothly, without any skewing.
7. Turn on the phone. Wait for the system to boot and check if the map is determined.

If the phone doesn't see the card after it's turned on, restart it again. Sometimes the system needs additional initialization. Also check if the SIM-only option is set in the settings (more on this below).

⚠️ Warning: Never remove the tray when the phone is on! This can cause contact damage or loss of card data. If the phone is getting stuck and doesn't turn off, force reboot (press the power button for 10-15 seconds).

Setting up a memory card in the system: formatting and use

Once you install the map, Xiaomi Redmi 5A will offer to format it. If the card is new, agree — it will delete all the data (if any) and prepare it for work. If the card already has files, first copy them to the computer.

To set up the map:

1. Go to Settings. → Memory.
2. Select a Memory Card (SD-map).
3. Click Format (if required) or Use as a portable storage.
4. To transfer data (photos, videos) to the map, use Settings → Memory → Transfer data.

If you want to use the card to install applications (partially), turn on the option Set by default on the SD-But remember, not all applications support external storage.

⚠️ Note: If you format the card as an internal storage, it cannot be retrieved and used on another phone or computer without losing data.

Frequent Problems and Solutions: Phone Can't See Memory Card

Sometimes, once you've installed a Redmi 5A card, it doesn't recognize it, and here are the most common reasons and ways to eliminate it:

• 🔌 The card is not inserted correctly. Turn it down with the contacts and see if it sits tightly in the slot.
• 🔄 The system didn't initialize the card. Restart the phone or retrieve/paste the card.
• 🛠️ File system is not supported. Format the card into FAT32 or exFAT on a computer.
• 🚫 The map is damaged. Try it on another device. If it doesn't work, replace it.
• 📱 The card slot is contaminated. Clean the contacts of the tray with a dry soft brush.

If the card is detected but the phone writes “damaged” or “unknown file system”, try formatting it via your computer (use official utilities such as the SD Card Formatter from the SD Association).

If none of these things worked, maybe the problem is with the slot itself, and in that case, go to the service center, and don't try to clean the contacts with alcohol or other liquids, because that can oxidize them.

How to transfer data to a memory card: photos, videos, applications

Once you install the card, it makes sense to transfer heavy files to it to free up internal memory. In Redmi 5A, you can do this in a number of ways:

• 📷 Photos and Videos: Open the Gallery, select files → Share. → Save it on. SD-map.
• 🎵 Music and Documents: Use Explorer (built-in or Mi File Manager) to move files manually.
• 📱 Annexes: C Settings → Applications select the program → Warehouse → Change. → SD-map.

To automatically save new photos and videos to the map:

1. Open the chamber.
2. Press on. ⚙️ Settings (cogs).
3. Select a Retention Site → SD-map.

Not all applications can be transferred to the map, for example, system programs (Settings, Phone) remain in internal memory, and some games (such as PUBG Mobile or Genshin Impact) may not be launched from an external drive due to protection against piracy.

💡

If you shoot videos frequently, set up automatic storage on the memory card, which will prevent internal storage overflowing and speed up recording (if the card is faster than internal memory).

Can I use a memory card as the primary storage in Redmi 5A?

Technically, Xiaomi Redmi 5A based on Android 7.1 Nougat supports Adoptable Storage, but with reservations:

• ✅ The card is formatted as an internal storage and encrypted.
• ✅ You can install a part of the applications.
• ❌ The card becomes tied to the phone – on other devices it can not be read.
• ❌ System speed may drop if the card is slow.

To activate this mode:

1. Insert the card and wait for notification of its detection.
2. In the window that appears, select Use as internal storage.
3. Confirm the formatting (all data will be erased!).
4. Wait until the process is completed (may take a few minutes).

After that, the card will be displayed as part of the internal memory, but we do not recommend this method for the Redmi 5A, as:

• Budget memory cards (Class 10) slow down the system.
• When you remove the map, the applications on it will stop working.
• Data recovery after formatting will not be possible.

💡

Use the memory card as a portable storage device (for photos, videos, music) rather than as internal memory.
