How to add a memory card to the total memory of the Xiaomi smartphone

Many Xiaomi and Redmi smartphone owners face the uncomfortable situation of having built-in storage overflowing, the system running slower, new apps not installed, and photos no longer being saved, and at such times a microSD card comes to the rescue, but the standard installation allows you to use it only as a removable medium.

There's a hidden Adoptable Storage feature that allows you to turn an external flash drive into a full extension of the system partition, which is not just file transfer, but deep integration, which makes the card part of the shared memory, but this process requires care, because an error can lead to data loss.

In this article, we will take a look at all the steps of memory expansion, including hidden Android settings. You will learn how to properly prepare the drive and what risks exist when using old or slow cards. It is important to understand that once formatted, the card will become unreadable on other devices without resetting.

โš ๏ธ Attention: The process of formatting the card into internal memory is irreversible, all data stored on it will be destroyed.

Compatibility check and selection of memory card

Before you start technical manipulation, you need to make sure that your device and the drive itself are ready for this work. Not all Xiaomi smartphones support the Adoptable Storage feature at the firmware level, although the hardware usually allows. MIUI or hyperos.

Card speed is critical, and if you're using an old Class 4 or Class 6 drive, it can be unstable, it requires UHS-I or higher to work comfortably, and a slow card will lead to interface friezes and long application downloads.

  • ๐Ÿ“ฑ Make sure that the smartphone has a memory card slot (separate or combined with the device). SIM).
  • โšก Check the marking of the card: look for the designations A1, A2 or V30 speedily.
  • ๐Ÿ” Insert the map and go to Settings โ†’ The phone. โ†’ Memory to see its volume.
  • ๐Ÿ’พ Make sure the card is in good working order and has no physical damage to contacts.

If you plan to install a 128GB or 256GB card, make sure the file system meets the requirements. Modern versions of Android prefer exFAT for large volumes, but for the merger procedure, the system itself will offer to reformat the drive to the desired format.

Preparing for Formatting as Internal Memory

Xiaomiโ€™s standard settings interface often hides the memory merge option, which requires you to activate developer mode or use the command via ADB (Android Debug Bridge) to back up important data from card to computer.

Then you need to activate the developer menu. To do this, go to Settings โ†’ About Phone and quickly click on the MIUI version seven times. Once the notification โ€œYou became a developerโ€ appears, additional system functions will be accessed.

โ˜‘๏ธ Preparation of the device

Done: 0 / 1

In the developer menu, find the item "Do not turn off the screen when charging" and activate it so that the process does not interrupt, and it is also worth turning off all energy-saving modes that can block the system during formatting.

If you don't want to use a computer, try to find the hidden item in the storage settings, which sometimes appears if you have a card inserted into the slot and your internal memory is over 80% full. ADB-team.

Instructions: Activate Adoptable Storage via ADB

This is the most efficient way to work on most Xiaomi, Redmi and other models. POCO. You will need a computer with Windows, USB-Cable and Platform Tools. Connect your smartphone and allow debugging. USB window-in.

Open the command line on your computer in the ADB folder and enter the adb device command to check the connection. If the device is displayed with device status, you can proceed to the next step.

adb shell sm list-disks

You'll get a disk ID, like disk:179.64, and remember or copy these numbers, they're unique to your device, and you'll need to format the card as internal memory by following the command:

adb shell sm partition disk:XXX,XX private

Instead of XXX,XX, substitute your numbers. Once you've done the command, the system will overwrite the map structure. The smartphone can reboot. Once you turn on the storage settings, the card will appear as part of the internal drive, not as a removable medium.

What to do if the team is not executed?
If you get a Command Not Found or Permission Denied error, make sure your smartphone is debugging USB and checks "Always Allow from this computer." Also, some Global firmware may block this command, then you will need to flash it to the Chinese version or use root rights.

Transfer applications and data to new memory

Once formatted successfully, the system will automatically start using the new memory to install applications. However, the old programs will remain on the built-in drive. To move them, go to Settings โ†’ Applications โ†’ All applications.

Select the desired application from the list. If the program supports portability, you will see the "Move" or "Modify" button in the storage section. Press it and select the memory card. Note that the system applications of Xiaomi and Google cannot be migrated.

Photos and videosYes (automatically)DCIM folder on SDLow.
Cash messengersPartially.Android/dataMedium (may fly)
Games (OBB files)Yes.Android/obbLow.
System filesNo.Internal sectionTall (do not touch)

For multimedia files, it is best to set up automatic saving. In the Camera settings, change the save path to a memory card. Telegram and WhatsApp also have separate settings for the file download path, which should be changed manually.

After you've moved heavy games, go to them and check the downloads. OBB-files if the game does not see data in the new location.

Possible problems and ways to solve them

There may be some disruptions in operation, and users often complain that applications stop running or are not running smoothly, which may be due to a slow card write speed or file system corruption.

If the system writes "SD-The card is corrupted" or "Formatting required" and don't rush to format it again if there's important data in it. Try to extract the card, connect it to your computer and check for errors through chkdsk on Windows.

  • ๐Ÿ“‰ Interface brake: The map probably doesn't pull the speed. Replace it with a model labeled A2.
  • ๐Ÿ“ต Applications won't open: Check if the card is disabled in the settings. Sometimes it helps to reboot.
  • ๐Ÿ”‹ Fast discharge: Constant work with external memory increases the power consumption of the processor.

In some cases, cleaning the system cache helps. Go to Settings โ†’ Advanced Settings โ†’ Memory and clean up garbage. If problems persist, you may have to return the card to removable media status, which will require re-formatting and data loss.

โš ๏ธ Note: If you pull out a card formatted as internal memory and paste it into another phone, the data will not be read.The card is tied with a cryptographic key to a particular device.

The stability of the smartphone with Adoptable Storage depends on the quality of the memory card. Savings on the media will lead to a loss of performance of the entire device.

Alternative methods of expanding space

If you find Adoptable Storage too risky or too complex, there are other ways to free up space, such as using cloud storage, and services like Google Photos or Yandex.Disk allow you to store your media library in the cloud, freeing up gigabytes on your device.

You can also use the Cleanup feature in Xiaomi's standard Security app, which finds duplicates, large files and remnants of deleted applications, and regular cleaning helps keep the system in good shape without expanding memory.

Another option is the use of OTG-These are external drives that connect through the charging connector, and they're convenient for temporarily storing archives or watching movies, but they're not suitable for installing applications.

Does it work on Android 13 and 14?
In newer versions of Android, Google is actively fighting memory sharing, so Adoptable Storage is often hidden or removed, but on MIUI and HyperOS firmware, ADB teams often continue to work because the kernel retains this capability.

Return to baseline

If you're going to give up the idea of shared memory, you need to format the card as a portable medium, and you can do this through your smartphone settings: Settings โ†’ Memory โ†’ SD Card โ†’ Format. Select the option "Use as a portable storage".

The system will alert you to data loss, and once the process is complete, the card will be readable on any device, and any applications that are ported to it will stop working and require reinstallation or return to the internal drive.

Remember that frequent formatting reduces the memory cardโ€™s life, and if you plan to change cards often, you should use them only for photos and videos, without having to combine partitions.

Frequently Asked Questions (FAQ)

Can I return the card to normal mode without losing data?
Unfortunately, no. The process of changing the mode of operation of the map (from internal to external and vice versa) always requires full formatting, the data must be stored on the computer or in the cloud in advance.
Will the phone speed up after memory expansion?
No, itโ€™s likely to get slower if the card isnโ€™t fast (U3/A2 class).A smartphoneโ€™s internal memory (UFS) is always faster than most microSD cards.
Will the warranty work when using ADB commands?
Using USB debugging and standard sm commands is not hacking or flashing, so the warranty doesn't formally fly off, but if you damage the software, the service center may refuse to repair it free of charge.
What is the maximum card size that Xiaomi supports?
Officially, most modern models support cards up to 256 GB or 512 GB, but in practice, 1 TB cards often work as well, if they are formatted in exFAT.
