How to install applications SD-Map Xiaomi Redmi: the full guide

Why Xiaomi Redmi does not always allow you to install applications SD-map

Owners of Xiaomi Redmi smartphones often face the problem of lack of internal memory, especially on budget models with 32 or 64 GB of storage. SD-But here, the user is in for a nasty surprise: not all apps support this feature. MIUI, It is based on Android, but has its own rules for working with external media.

With Android 6.0 Marshmallow, Google introduced the concept of Adoptable Storage – the ability to format SD-The card is part of the internal memory, but Xiaomi has partially blocked this feature from the memory. MIUI, And that's just for specific regions and models, like the Redmi Note 10 Pro or the Redmi Note 10 Pro. POCO X3 The Pro option may not be on the menu, whereas older Redmis may not be available. 5A It's still available, or Redmi 7, because it's a security policy, because the manufacturer fears that slow memory cards are lower in class. UHS-I (U1) slow down the system.

Another reason for the limitations is performance, and even if the card is formatted as internal memory, it's going to run slower than the built-in storage. eMMC/UFS. This can lead to lags in games or slow app loading, however, for most users, migrating instant messengers, social media or multimedia apps to the mobile app. SD-The map remains a relevant solution.

What are they? SD-The cards are suitable for installing applications on Xiaomi Redmi

Not every microSD card will be able to extend memory for applications. To work in Xiaomi Redmi, the media must meet several criteria:

• 🔹 Speed class: minimum Class 10 or UHS-I (U1). For games and heavy applications, it is better to choose U3 or V30.
• 🔹 Volume: from 32 GB (on cards less than 32 GB Adoptable Storage function may not work). Optimal - 64-128 GB.
• 🔹 Manufacturer: Preference SanDisk, Samsung, Kingston or Lexar brands. Cheap no-name cards are often forged, indicating overrated characteristics.
• 🔹 File system: Formatting as internal memory will require ext4 or f2fs (automatically selected by the system).

Important: If you plan to use the card only for storing files (photos, videos, music) and not for applications, Class 4 or Class 6 will suffice, but such cards will not be suitable for installing programs - the system simply does not offer the option of formatting as an internal drive.

⚠️ Note: After formatting SD-It's not going to be used in other devices without being completely cleaned, and all the data on it will be encrypted and only available on this smartphone.

Step-by-step instructions: how to format SD-map as an internal memory

If your Xiaomi Redmi model supports Adoptable Storage, follow this instruction. Be sure to back up your card data before you start – all files will be deleted!
