How to combine SD card and internal memory on Xiaomi Redmi 8T

Xiaomi Redmi 8T series smartphones, despite their popularity and reliability, often face the challenge of lacking an embedded drive. The basic versions of the device can offer just 32 or 64 gigabytes of space, which is rapidly filled with system files, messenger cache and heavy applications. Users are looking for ways to expand the usable volume to avoid constant notifications of overflow storage.

Fortunately, Android provides a mechanism to turn an external microSD card into a full extension of internal memory, a process known as adaptive storage that allows the system to perceive the memory. SD-map as part of the main section, but in the shell MIUI, redmi-mounted 8T, This feature is often hidden from the user and requires the use of special commands to activate the user.

In this article, we will discuss how to safely and efficiently combine the resources of the drives. You will learn about the preparation of equipment, necessary tools and step-by-step algorithm of actions. Memory integration is possible only on a formatted card, which will lead to the complete deletion of all data on it.

Preparation for storage expansion and choice of memory card

Before you start technical manipulation, you need to make sure that your hardware is ready to go. Not every memory card is suitable for use as a system partition. Read and write speed is critical here, because it depends on the speed of the entire smartphone. Using slow cards can lead to interface lags and applications freeze.

It is recommended to use cards of UHS-I standard or higher, with a speed class of at least 10. The optimal choice will be cards with a volume of 32 to 128 gigabytes, as they provide a better balance between cost and performance. Larger cards are also supported, but their formatting will take longer.

  • πŸ“± Make sure the Redmi battery is charged 8T At least 60% before the procedure begins.
  • πŸ’Ύ Make a backup of all important files with SD-Cards to the computer or the cloud.
  • πŸ”Œ Prepare quality. USB-cable.
  • πŸ“₯ Download and install drivers ADB on your computer.

⚠️ Note: During the setup process, the memory card will be formatted into the file system. ext4 or f2fs. After that, it will not be read on other devices (cameras, other phones) without re-formatting, which will also delete all data.

Compatibility check is an important step. Although Xiaomi Redmi 8T officially supports large-volume cards, some memory card manufacturers may use custom controllers. If the system fails or the card is unstable after formatting, try using a different brand of media. The stability of the system depends on the quality of the drive used.

Necessary tools and setup debugging over USB

To do this, we'll need access to hidden operating system functions. The standard MIUI settings menu doesn't have a "Combine with internal memory" button, so we'll use the Android Debug Bridge (ADB) toolkit, which is a standard developer tool that lets you send commands directly to the system.

The first step is to activate the developer mode on your smartphone, and without that step, the computer won't get the necessary permissions to control the device, and it's simple, but it takes care not to change the settings.

You need to go to the Settings β†’ About menu and find the MIUI version. Click on it quickly 7 times in a row until you notice that you have become a developer. Then a new section will appear in the main settings menu "Additional" or "Extended settings", where you need to find "For developers".

Inside the developer menu, find the USB Debugging Switch and activate it. The system will alert you to the potential risks of confirming the action. It is also recommended to turn on the option β€œDo not turn off the screen when charging” so that the smartphone does not fall asleep during the transmission of commands.

Step-by-step instructions for combining memory through ADB

Now that the preparatory work is complete, you can move on to the main part. 8T computer-to-computer USB-You'll see a request for debugging permission from that computer on your smartphone screen, and you'll be sure to click "Allow" and check "Always Allow" box".

Open the command line or terminal on your computer in the folder where the ADB is installed. Enter the adb device command to make sure the device is visible. If the list shows the serial number and the word device, then the connection is established correctly.

The next step requires a lot of precision. We need to know the disk ID.

adb shell sm list-disks

In the answer, you'll see something like disk:179.64. Write down these numbers, they're unique to your device. Then start formatting and teaming.

adb shell sm partition disk:179,64 private 100

Here, private means private mode, and 100 indicates that you use 100% of the card's volume for internal memory. If you want to leave some space for photos and videos that you can transfer, say 50 or 70.

What to do if the team is not executed?
If the command returns an error, make sure that the card is not important data. Sometimes you need to format the card as portable first through the standard settings menu, and then repeat the ADB command. Also check if the storage is not fully occupied by the system - free at least 500 MB.

Comparison of storage modes

Users often confuse portable storage and internal memory, and understanding the difference between these modes will help avoid frustration and data loss. Xiaomi Redmi 8T has a flexible drive management system, but it has its limitations.

The portable storage mode allows you to store media files that are available to other devices. This is ideal for photo archives and music. The internal memory mode (which we activate) encrypts the data and makes it available only to that particular smartphone. Applications installed on such a partition will cease to work if you extract the card.

Speed of operationStandard.Optimized for the system

When you choose private mode, you sacrifice data mobility to enhance smartphone functionality, a solution that is suitable for those who actively use heavy apps and games and who have nowhere to install them. For ordinary users who store thousands of photos, a hybrid version or the use of cloud services may be more convenient.

Once you combine the memory, go to Settings β†’ Memory and Storage. You'll see a single volume. The system may suggest that you move some applications automatically -- you'll agree to free up space on the embedded chip.

Application portability and data management

Once successfully combined, Android will begin to behave as if it had more internal memory, but the old apps won’t move on their own instantly. You’ll need to manually manage the data distribution to get the most out of it.

Go to Settings. β†’ Annexes β†’ All applications. Select a heavy application (e.g. social network or game) If the application supports portability, you will see a button "Change" or "Move to" SD-Click on it and confirm the action.

Not all applications allow this transfer. Developers can prohibit installation of their products on external drives for security or stability reasons. In such cases, the system will decide where to store data, but cache and updates will often be loaded to the extended partition automatically if the main space is not enough.

  • πŸš€ Move games with a large amount of cache first.
  • πŸ“Έ Set the camera to save the photo immediately on SD-map.
  • πŸ—‘οΈ Clean the messenger cache regularly, as they take up a lot of space.

⚠️ Warning: Do not remove the memory card while the smartphone is on.In combined memory mode, this can lead to system crash, loss of unsaved data and damage to the application database.

Possible problems and ways to solve them

Memory expansion doesn't always go smoothly. Redmi 8T users may encounter a number of typical problems, most often related to memory card quality or MIUI shell software failures. Knowing how to solve these problems will save you time and nerves.

If the phone is slow after formatting, it may not be fast enough to run the card, so you should replace the media with a faster one, and there is a problem with cycling reboot after partition. If that happens, try booting into Safe Mode or resetting.

Sometimes the system writes "SD-This may mean that the file system has been broken. Try formatting the card through the phone's settings menu (as portable) and then repeating the procedure again through the phone's ADB. In rare cases, it helps to update the firmware of the smartphone to the latest version.

The stability of the smartphone with combined memory by 90% depends on the quality and speed of the used memory. SD-Savings on the media will lead to interface brakes.

It's important to understand that memory integration is a software emulation, that the chips are physically different, but logically they are a single unit, that puts a strain on the memory controller, and that you keep track of the temperature of the device when you're working, especially when you're playing games or recording videos.

Can I get it back without losing data?
Unfortunately, no. To cancel the integration, the map will have to be re-formatted, which will destroy all the data on it. Before returning to the factory configuration, be sure to transfer all important files to the computer or to the cloud. Apps installed on the map will stop running after formatting.
Why did 10-15% of the map’s volume disappear after the merger?
This is OK. Part of the space is reserved by the system for service needs, file system and memory cell wear alignment. In addition, manufacturers specify the volume in the decimal system (1 GB = 1000 MB), and the system counts in binary (1 GB = 1024 MB), which also creates a visual difference.
Does this affect the Xiaomi guarantee?
Use of the ADB-commands in itself is not a violation of the warranty, if you have not obtained root-right and unlocked the bootloader (Bootloader). However, if you bring your phone to a service with a damaged file system due to a poor quality memory card, repair may be refused, citing improper operation.
