Owners of Xiaomi Redmi Note 7 smartphones often face a lack of built-in storage, especially if the basic version of the device is only 32 or 64 GB. Modern applications are overgrown with “weight”, cache gigabytes of data from messengers and social networks, turning the use of the gadget into a fight for every megabyte of free space. Constant notifications about filling up memory are not only annoying, but can lead to serious system failures or the inability to take an important picture.
Fortunately, Android architecture and shell MIUI provide tools to solve this problem by using an external drive. SD-The card allows you to unload the system partition and speed up the interface, but this process has its own nuances that must be taken into account so as not to lose important data and not disrupt the operation of installed programs.
In this detailed guide, we’ll take a look at all the available methods of moving, from standard system tools to more advanced techniques. You’ll learn which apps can be moved and which ones are best left in your phone’s memory, and how to set up your device for maximum efficiency. Proper file system management is key to a long and stable life for your Redmi Note 7.
Preparation of memory card and compatibility check
Before you start manipulating data, you need to make sure that your external drive is ready to work actively in conjunction with your smartphone. Not every MicroSD card is suitable for installing and running applications, since read and write speed is critical. If you use a slow card of a class 2 or 4, you risk getting lags in the work of programs and long downloads.
It is recommended to use UHS-I or UHS-II cards with a speed class of at least 10 (denoted by the number 10 inside the letter C or the letter U with a number). For Xiaomi Redmi Note 7, drives ranging from 32 to 128 GB will be the best choice, although the device supports large volumes. Be sure to format the card before installing.
⚠️ Note: Formatting will completely remove all data from the memory card. be sure to back up photos and documents on your computer before starting the procedure.
The formatting process is best done directly on your smartphone, so that the file system is adapted to the needs of Android. Put the card in the slot, wait for the notifications and go to the settings. The system will suggest that you prepare the drive for operation.
- 📀 Select a card marked with A1 or A2 for better application performance.
- 🔒 Use a card adapter to copy files to your computer before formatting.
- 📱 Make sure your phone battery is above 50% during formatting.
Once the formatting is complete, the system will create the necessary hidden partitions, and the drive is now ready to write data, but additional actions may be required to fully port the applications, which will be discussed below.
Basic method of transfer through MIUI settings
The MIUI shell on the Redmi Note 7 has built-in memory management functionality, although it is limited by Google's security policies. Starting with Android 6.0, the ability to port apps depends not only on the phone, but also on the support of the developer himself. If the developer has not added the appropriate flag to the code, the standard means to move the application will not work.
However, the first thing to check for portability is to open the settings and find the section that is responsible for installed programs, and it shows the space information and the actions available, and if the move button is active, you're lucky, and it'll take only a few seconds.
Settings → Applications → All Applications → [Select App] → Memory → ChangeThe menu that opens will have a choice of storage «SD-The map is available, click on it and confirm the action, the system will transfer executable files and libraries to an external medium, freeing up space in the internal partition, but for many system and key applications, this item may not be available (coloured in gray).
It's worth noting that even if you successfully transfer some of the data, it's still in the internal memory. DRM-Protect and store the user's personal settings, completely "push" the application to the map using standard methods in modern versions. MIUI It is almost impossible without special procedures.
☑️ Verification of portability
Use of the “As an Internal Storage” mode
There is a more radical method to bypass the limitations of the system – combining internal storage and SD-This feature, known as Adoptable Storage, was introduced in Android, but is often hidden by manufacturers. On the Xiaomi Redmi Note 7, it can be activated, turning the memory card into a full-fledged extension of the system disk.
This is a way of formatting the memory card into a format that is not readable on computers without unlocking, and all new applications and their data will be written to an external drive by default, which is the most effective way to solve the problem of space shortage, but it requires care.
⚠️ Warning: Once this mode is activated, it will be impossible to remove the memory card without losing data and resetting the phone settings.
To activate the hidden feature, you may need to connect to your computer and use USB debugging, as this option may not be available in the usual settings menu.If you decide to go this way, make sure your memory card has a high write speed, otherwise the phone interface will start to work noticeably slower.
| Parameter | Standard regimen | Like an internal storage facility. |
|---|---|---|
| Access to PC | Possible. | Impossible (without formatting) |
| Portability of applications | Selective | Automatic. |
| Speed of operation | Depends on the app. | Depends on the speed of the card. |
| Security of data | Medium | High (encryption) |
If you change memory cards frequently or use the same card for different devices, this method is not suitable for you. It is ideal for static use, where the card is inserted into the phone once and forgotten.
Risks of using Adoptable Storage
Advanced portability through ADB (for power users)
For those who are not afraid of the command line, there is the most powerful tool, Android Debug Bridge (ADB), which allows you to force the storage settings for any application, even if the developer has banned the transfer, it does not require Root rights, which preserves the device guarantee and the security of banking applications.
The essence of the method is to send a special command that changes the default installation prefix. After completing the command, all new applications will be installed on the device. SD-map, and the old can be moved through the standard settings menu, where previously hidden opportunity will appear.
adb shell pm set-install-location 2Where the number 2 indicates the priority of external storage. To return to factory settings, the command with the number 0 is used. It is important to understand that this does not move the already installed applications automatically, but only allows the system to do this through the settings menu. You still have to go to the settings of each heavy application and press the move button.
- 💻 Download the Platform Tools package from the official Google website.
- 🔌 Put the debugging on. USB In the menu "For developers" on Redmi Note 7.
- 📲 Connect your phone to your PC and authorize the connection on your smartphone screen.
Using ADB provides flexibility, but requires caution. Incorrect use of commands can lead to unstable operation of individual services. Always check where the application is installed before deleting installation files.
💡
If the ADB command does not show a move button, try to remove updated versions of Google Play system applications, leaving only the factory version, then repeat the procedure.
Cache cleaning and multimedia work
Even after transferring applications, the main amount of memory is often not the programs themselves, but their data: cache, downloaded files in messengers, offline maps and music. Apps like Telegram, WhatsApp and YouTube can steal tens of gigabytes. Transferring the application itself to the card does not always transfer its cache, so manual cleaning or setting up save ways is mandatory.
In most messenger settings, you can specify a way to save downloaded files. Change this path to yours. SD-This is especially true for group chats, where video and photo sharing is done around the clock.
You should also clean your system services and browser cache regularly, and MIUI has a built-in Security app that has a Cleanup feature, and use it weekly to delete temporary files that the system no longer needs to run fast.
⚠️ Warning: Do not use aggressive third-party cleaners from the Play Market. They often consume resources and display ads, and embedded funds. MIUI It is quite enough to support the Redmi Note 7.
To work with photos and videos, set the camera so that the pictures are immediately saved to an external drive, which will prevent the internal memory from filling up quickly during long walks or trips when there is no possibility to connect the phone to the computer.
💡
Regularly cleaning the messenger cache frees up more space than transferring lightweight apps to a memory card.
Typical problems and their solution
In the process of memory optimization, users may encounter a number of difficulties, sometimes after transferring the application stops running or crashes immediately after opening, this may indicate a slow read speed of the card or damage to its file system, in which case it is recommended to return the application to internal memory and replace the drive with a faster one.
Another common problem is that widgets from portable applications disappear from the desktop, and the shortcut may disappear after moving, and it will have to be added again through the menu of all applications, and updates to such programs can temporarily block their launch until the verification process is completed.
If the system says that the space is not vacant, although the application is moved, check the Android/obb folder. Often the "heavy" game data is there, and it needs to be moved separately or used by the file manager to create symbolic links, which requires more in-depth knowledge.
- 🔄 Reboot the device after mass data transfer to redistribute resources.
- 🔍 Check the map for errors through the storage settings menu.
- 📉 Watch the temperature of the phone, as active writing to the card can cause heating.
Understanding these nuances will allow you to avoid disappointments and make work with Xiaomi Redmi Note 7 comfortable even with a large number of installed programs. Proper memory management prolongs the life of the device and maintains its performance.
