How to install applications on an SD card in Xiaomi Redmi Note 8T

Owners of the popular Xiaomi Redmi Note 8T smartphone often face limited storage, especially if you use the basic version of the device at 64 gigabytes. After installing the necessary social networks, messengers and navigators, the free space begins to run out, which leads to slowdown and inability to install new updates. Using a microSD memory card is the most effective way to expand the capabilities of the gadget without having to buy a new phone.

However, the Android operating system in the shell of MIUI has its own features with external drives that are not always obvious to the average user. Standard methods of transferring programs are often hidden in the engineering menu or require the use of third-party software to activate full functionality. In this article, we will discuss in detail all available ways to optimize memory, including working with system settings and using specialized filters that allow you to turn a flash drive into a full continuation of internal memory.

Before you start taking action, you need to understand the difference between simple file storage and system extension. MIUI It does not allow the transfer of heavy applications to the SD card ADB-commands or special launchers, so it is important to follow the instructions clearly to avoid data loss or unstable operation of the device.We will consider both safe methods for ordinary users, and more advanced techniques for experienced owners.

Preparation of memory card and smartphone for work

The first and most important step is the right choice and preparation of the drive, since its characteristics directly affect the speed of the entire smartphone. Cheap cards with a low speed class can cause interface lags and long downloads of applications, so save on this component is not worth it. For the Redmi Note 8T, it is recommended to use UHS-I cards with a speed class of at least 10, which will ensure the comfortable operation of most programs.

After purchasing a suitable drive, you need to insert it into a slot located on the end of the device next to the tray for SIM-Be very careful when removing the tray, using a special paper clip so as not to damage the mechanism or the card itself. After physical installation, the system automatically prompts the media to be formatted, and this step should not be skipped.

• 📱 Select the option “Use as portable storage” in the notification that appears to maintain compatibility with other devices.
• 💾 If the system didn’t offer formatting, go to the settings and find the “Storage” section for manual initialization.
• 🔄 Wait for the formatting process to finish, which can take anywhere from 30 seconds to several minutes depending on the volume.

⚠️ Note: Formatting completely removes all data from the memory card, so pre-copy important photos and documents to your computer or cloud storage if something is already written on the flash drive.

Once formatted successfully, the system will assign a card a letter or a name, and it will be available for file writing through the file manager, and the preparatory stage is considered complete, and you can proceed to configure the system to work with applications. It is important to make sure that the map is determined correctly and displays the correct volume in the storage settings.

Standard methods of data transfer in MIUI

The MIUI shell provides basic file management functionality that allows you to manually move media content and documents to an external drive.This frees up precious space in the internal partition for installing new programs and system updates. The user can transfer photos, videos, music and uploaded documents using the built-in Explorer application.

To perform the transfer, you need to open the file manager, select the desired files or folders and select the move function. SD-This method is the most secure and guaranteed to work on all versions of the firmware without the risk of damaging system files.

However, it is worthwhile to understand that the standard means to transfer the applications themselves (APK-Files and data are not always available, many software developers block the ability to install external media for security and stability, but for some system utilities and simple games, this option can be accessed through settings.

To check if you can port a particular application, go to the settings section, select "Applications" and find the desired item in the list. If the developer has authorized the move, there will be an active button "Move to the "Applications" button. SD-Otherwise, the button will be missing or inactive, which requires the use of alternative methods.

Use of extended storage

You can force the system to consider the memory card as part of the internal storage, which allows you to install applications there by default, this method requires you to turn on the hidden settings of the developer and use the command through a computer or a special application terminal, a process that is more complex, but it gives the maximum result in the struggle for free space.

To start, you need to activate the developer mode by clicking on the MIUI version several times in the About Phone section. Once the corresponding notification appears in the settings menu, a new "Developers" item will appear, where you need to find the "Default Install Applications on an external drive" option and activate it.

Once this option is activated, it is recommended to restart the device so that the changes take effect. Now, when installing new programs, the system will default to offer a memory card as a place to place if the application supports such a feature. However, for already installed programs, this method may not work without additional intervention.

In some cases, you need to use the command adb shell pm set-install-location 2, which forcibly changes the priority of the installation. To perform this command, the smartphone connects to the computer in debugging mode via USB, and the command is entered through the console ADB. This action is more risky and requires careful input parameters.

Working with file managers and analysis

To effectively manage space, it's not enough to just move files, you need to understand what exactly takes up space. Built-in analysis often shows the big picture, but does not detail the cache of individual applications. Using advanced file managers allows you to see hidden folders and clean up debris that accumulates for months.

Applications like Total Commander or FX File Explorer provide easy access to the root structure of the file system (without root rights), which can manually transfer folders with heavy content, such as maps for the navigator or offline dictionaries, freeing up internal memory.

Special attention should be paid to the Android/obb folder, where the cache files of heavy games are stored. Moving this data to a slow memory card can lead to long loads of levels and twitching graphics. If your card has a low read speed, it is better to leave these files in internal memory.

Problems and Limitations When Working with an SD Card

Despite the benefits of using an external drive, Redmi Note 8T users may face a number of restrictions imposed by Google and Xiaomi’s security policies, a major obstacle that today’s apps increasingly require data to be stored in an internal secure partition.

A sudden card shutdown or read error is a common problem, especially if the drive is old or low quality. The system may stop seeing files and applications transferred to the flash drive will stop running until the malfunction is corrected. This can lead to loss of progress in games or program settings.

⚠️ Note: It is not recommended to transfer to SD card data of banking applications and messengers with important correspondence, as if the card fails, access to information will be lost, and recovery may be impossible.

Another nuance is the speed of work: even fast microSD cards are inferior in speed to write and read the internal memory of a smartphone like UFS. This means that the launch of applications from the flash drive will always be slower, and in some cases there may be delays when saving data.

If you notice that after transferring data, the phone started to slow down or programs crashed, try to return files back to internal memory. Sometimes it helps to re-format the map in the exFAT file system, which works better with large amounts of data on Android.

Frequently Asked Questions (FAQ)

To conclude, we will look at some of the most popular questions users have when trying to optimize their device memory, and the answers will help avoid common errors and help them understand how the system works.

💡

Use only trusted brands (SanDisk, Samsung, Kingston) and buy them from official stores to avoid compatibility issues and data loss.

💡
