Important: Not all applications can be transferred to SD-System utilities (Settings, Phone, Messages) and some games (such as Genshin Impact) will remain in internal memory. Also note that once the card is formatted as an internal drive, it will not be read on other devices without formatting it.

1. Preparation SD-maps: formatting and compatibility check

Before transferring data, the memory card must be properly prepared. Incorrect formatting is the main cause of errors such as "SD-"Card damaged" or "Inadequate rights to record." Here's how to avoid problems:

First, insert the card into the slot (in models with a hybrid slot, for example, the Redmi Note 13 Pro, you will have to choose between the second one). SIM and SD). Then go to Settings. β†’ Warehouse β†’ SD-The system will offer two use cases:

  • πŸ“± Portable storage: the card works like a flash drive, files are transferred manually.
  • πŸ–₯️ Internal memory: the card becomes part of the system (requires formatting, data will be deleted!).

For full application transfer, choose internal memory, but remember:

⚠️ Note: After formatting as an internal drive, the card cannot be retrieved without losing data, it will also become "bound" to the device and will not be read on a PC without additional manipulation.

If the map is not determined:

  1. Check it on another device (for example, on a PC through a card reader).
  2. Update MIUI to the latest version – older versions had bugs with exFAT card recognition.
  3. Try formatting the card on a PC in FAT32 (use the SD Formatter utility from the SD Association).
Why Xiaomi doesn’t see why SD-128GB card+?
Some models (e.g. Redmi 9A) have a maximum card size limit of 64 GB, which is due to the hardware features of the memory controller, so you can either use a smaller card or upgrade to MIUI 14+ (new versions remove the restriction).

2. Transfer of applications to SD-map: step-by-step instruction

Application portability is the most difficult step, because MIUI blocks this feature for most system and popular programs, but for supported applications, the algorithm is as follows:

Open the Settings. β†’ Annexes β†’ App management. Select the application you want (like Telegram or Spotify) and click Storage. If the Change option is active, select SD-map and confirm the transfer.

What to do if the "Change" button is inactive?

  • πŸ”§ Check if the card is formatted as internal memory (portable storage does not support application portability).
  • πŸ”§ Some apps (like WhatsApp) block the transfer for security reasons.
  • πŸ”§ Use it. ADB-commands for forced transfer (instruction below).

For advanced users: transfer via ADB (requires a PC and enabled debugging over USB).

adb shell pm set-install-location 2

This command forces the system to install new applications on the SD-The default card. To get the settings back, use:

adb shell pm set-install-location 0
