How to connect a memory card to Xiaomi Redmi 5: from choosing a microSD to setting up storage

Xiaomi Redmi 5 is one of the most popular budget smartphones of the brand, but its internal memory (16 or 32 GB) often becomes a bottleneck for users. Connecting a microSD card solves the problem of space shortage, but requires the right approach: from choosing a compatible drive to setting up in MIUI. In this article, we will analyze all the nuances – from the physical installation to the software subtleties, including the unique limitations of the hybrid slot in Redmi 5.

It is important to understand that Redmi 5 supports memory cards up to 256 GB, but with reservations: when using a hybrid slot (combined with a single card). SIM-You'll have to sacrifice the second SIM card, MIUI imposes restrictions on the transfer of applications – not all programs can be moved to SD. We will show you how to get around these limitations and make the most of the additional storage.

Which memory card to choose for Xiaomi Redmi 5

Not every microSD is suitable for Redmi 5.The smartphone supports microSDXC cards (up to 256 GB), but there are nuances:

• 🔹 Speed class: minimum Class 10 (UHS-I), Otherwise, you'll be lagging when you're recording videos or transferring files. UHS-I U3.
• 🔹 Brand: Give preference to proven manufacturers – SanDisk Ultra, Samsung EVO, Kingston Canvas – Cheap no-name cards are often forged.
• 🔹 Size: optimally 64-128 GB. 256 GB cards can run slower due to controller limitations in budget smartphones.

Note that Redmi 5 does not support microSDHCs of 512GB or higher, despite the fact that some vendors market them as “universal.” Also avoid cards labeled A1/A2 (for Android) – they are more expensive, but in Redmi 5 their advantages are not realized due to hardware limitations.

Hybrid slot: how to combine a memory card and two SIM-map

Redmi 5 is equipped with a hybrid slot, which means that you can install either two nano-SIMs or one SIM + microSD. If you need both SIMs and a memory card at the same time, there are two options:

1. The 2 SIM + microSD adapter (such as from Baseus or Orico) allows you to insert two nano-SIM and microSD into one slot, but takes up more space and can not fix well.
2. Using eSIM (if your carrier supports). Redmi 5 does not have eSIM hardware support, but you can activate a virtual SIM through an operator application (for example, MTS Connect or Beeline). SIM-manager).

⚠️ Attention: adapters "2 SIM + MicroSDs can cause network loss when a smartphone vibrates or falls. If you use mobile internet frequently, it is better to sacrifice a second SIM for a memory card.

Step-by-step: Install a memory card in Redmi 5

Before installing, be sure to turn off your smartphone - hot card replacement can damage the file system.

Turn off the smartphone (click the power button → “Switch off”)

Remove the tray for SIM-cards by means of a paper clip or tool

Put the microSD in the slot with upward marks (contacts should be directed to the phone)

Insert the tray back before clicking

Turn on the smartphone and wait for card recognition-->

If the card is not determined after inclusion:

1. Check if the microSD is inserted correctly (the contacts should be clean, without scratches).
2. Reboot your smartphone.
3. Try formatting the card on your PC in FAT32 format (if it’s new or has been used in other devices before).

⚠️ Note: If you extract the memory card while recording files (for example, while shooting videos or transferring applications), there is a risk of damage to the file system. MIUI will offer to format the drive at the next connection.

Memory card configuration: external or internal storage

After installation, MIUI will suggest you to choose whether to use the card as a portable storage (external memory) or as internal memory (extension of the main drive).

• 📁 Portable storage: The card works like a flash drive, you can easily retrieve and connect to other devices. Applications are installed by default in internal memory. You can manually transfer some applications to the internal memory. SD (not all).
• 🔧 Internal memory: The card is formatted and encrypted, becomes part of the system. SD (You can't take out the card without resetting the phone to the factory settings.

To change the type of storage later:

1. Go to Settings. → Memory.
2. Tap on the memory card name (for example, SD-map: 64GB).
3. Select Settings → Format as internal (or vice versa).

💡

If you have chosen the “internal memory” mode, but the applications are still installed in the built-in drive, try manually transferring them through Settings → Applications → [Select Application] → Memory → Change.

Transferring applications to a memory card: limitations and workarounds

MIUI for Redmi 5 has strict restrictions on portability:

• ❌ You cannot transfer system applications (e.g. Google Play Services, MIUI Launcher).
• ❌ Some games (especially those with piracy protection) block the transfer.
• ❌ After the transfer, the application can run slower (depending on the card speed class).

To circumvent the restrictions:

1. Use the Adoptable Storage function (if the card is formatted as internal memory). To do this: adb shell sm set-force-adoptable true (requires enabled Developer Mode and USB connection with debugging).
2. Cache only: In some applications (for example, Spotify, YouTube) you can manually specify the path for downloads to SD.
3. Use symbolic links (for advanced users). Team example: ln -s /storage/emulated/0/Android/obb /storage/1234-5678/Android/obb (where 1234-5678 — identifier SD-map).

⚠️ Note: Forcing the card to be formatted as an internal memory (Adoptable Storage) may result in loss of warranty if the service center detects changes in the storage partitions. This method is also not recommended for cards larger than 128 GB, as there may be failures due to file system limitations. f2fs into MIUI.

Frequent mistakes and their solution

Redmi 5 users often face the following problems when working with a memory card:

If the memory card is no longer defined after the MIUI update, try:

1. Clear the system cache (Settings → Memory → Cleanup → Cash).
2. Reset network settings (Settings) → SIM-maps and mobile networks → Resetting network settings).
3. Reverse to the previous version of the firmware (if the error appeared after the update).
