How to make an SD card the main memory on Android Xiaomi

If you type in a "device unauthorized" error, check the phone screen. There should be a debugging request, which you must verify with the "Always Allow" tick and the "OK" button. USB-Once you get the disk ID, you can start the most important part of the procedure. The sm partition command causes the system to format the map and create a secure file system on it. The syntax of the command requires accuracy. adb shell sm partition disk:XXX,XX Private 100 Instead of disk:XXX,XX If you want to leave some space for normal file storage (available through the file manager as an external drive), you can specify, for example, 50. Once you input the command, it takes from a few seconds to a couple of minutes, you can't turn off the cable or take out the card, and when you do that, the phone can automatically reboot, and you'll see that the storage menu has increased the amount of internal memory. The system may suggest moving the data of already installed applications to a new volume, and it is recommended to accept this proposal to make room in the main section. Some system applications will still remain on the embedded chip, but user content will move. Even after successful memory integration, not all applications automatically move to the map. You need to manually manage this process through the settings. Go to Settings → Annexes → All apps. Select a heavy app (e.g. social networking or game). If transfer is possible, there will be an active button Change or Move next to the storage location. Press it and select. SD-map. Data type Transferability Speed Impact Recommendation System applications Impossible High Leave on internal memory Heavy games Partially Medium Cache Transfer Social networks Possible Low Be sure to transfer Photos and Videos Automatically Low Set up in the gallery For Photos and videos are best set to automatically save to the map. In the Camera app, go to the settings and turn on the option Save to the map. SD-In messengers like Telegram or WhatsApp, the path to the download folder can also be changed in the settings of the application itself. 💡Use Google’s Files app or built-in Explorer to move large folders with documents and downloads manually, simply by cutting and pasting them into the root. SD-map. Possible problems and solutions In the process of operation, there may be situations when the system stops seeing the map or applications begin to work unstable, often due to the poor quality of the drive itself or a violation of the file system "SD-The card is "damaged" or constantly suggests you format it, try to extract the card, paste it into a PC card reader and check for errors with standard Windows tools. FAT32 and repeat the procedure through ADB. ⚠️ Note: If after the firmware update MIUI or HyperOS is no longer defined as an internal card, don't format it right away. Try simply restarting the device or re-run the mount command via the device. ADB. Another common problem is the slow operation of the phone. This is a sure sign that the speed of the memory card is not enough to work as a system disk. In this case, the only solution is to replace the drive with a faster one. Alternative methods and third-party utilities For users who do not want to mess with the command line, there are assistant applications such as SD Maid or specialized scripts. However, most of them require Root rights, which can be difficult or impossible to obtain on new Xiaomi models without unlocking the bootloader. Unlocking the bootloader is an official procedure from Xiaomi, requiring a wait from 7 to 30 days, but it can break all the data from Payle, but it can stop using the system from working with additional applications. If you don't have root rights, ADB remains the only safe way. Don't try to use questionable apps from the Play Market that promise to "accelerate memory" with a single click - they are often advertising junk and don't have access to system partitions. The impact on performance and lifespan of using a memory card as the primary storage has its consequences. As mentioned earlier, speed can decrease if the card is slower than the built-in memory chip of the phone. Modern smartphones use memory like UFS 2.1/3.1, which is much faster than most microSD cards. It's also worth remembering about overwriting cycles. Memory cards have limited resources. When you actively work with data, you can read important applications more quickly than you use the card. However, for budget models with a small amount of internal memory (32-64 GB) is often the only way to extend the life of a device and continue to use current versions of applications that are becoming increasingly "heavy." SD-Xiaomi's internal memory card? It's safe for the phone if you use a high-quality memory card. The only risk is that the card itself might lose data or fail due to heavy load. Android is stable with split memory. Can you take out the card after formatting and paste it into another phone? No, you can't read the data. When formatting into internal memory mode, the card is encrypted with the device's key. In another phone (or after resetting the current one), the system will require you to format the card, deleting all data. Why the "Move to the button" SD-The map is inactive for some applications? App developers decide whether to transfer it to an external medium. Many modern programs require high speed data access, so developers prohibit their installation on slow. SD-Will the setting reset after the update? MIUI? Usually, the setting is saved because it is written to the system partition. However, major Android updates (for example, the transition from Android 13 to 14) can sometimes reset the storage configuration, and the procedure will have to be repeated. What is the maximum card volume supports Xiaomi? Officially, most smartphones support cards up to 256 GB or 512 GB. However, in practice, devices often see and work correctly with 1 TB cards if the file system is formatted correctly (exFAT).
