The problem of lack of built-in storage in smartphones of the budget segment is familiar to many users. Xiaomi Redmi 7, despite its decent characteristics for its time, often equipped with a limited amount of internal memory, which is quickly filled after installing modern “heavy” applications and accumulating multimedia content. Android system over time acquires cache, updates and temporary files, which leads to a critical slowdown of the interface and the inability to install new programs.
Device owners often wonder how to effectively free up precious space without losing functionality. Moving applications to an external drive is one of the most effective solutions to this problem, allowing you to keep the system running. In this article, we will discuss in detail all the nuances of working with SD-shell-card MIUI, Consider the formatting and configuration process, and discuss the limitations of the current version of the Android operating system.
Preparation of memory card and smartphone for work
Before you start transferring data or changing storage settings, you need to make sure that the storage drive used is compatible and serviceable. Xiaomi Redmi 7 supports microSD, microSDHC and microSDXC cards, which allows you to use media up to 256 GB or even more, although officially the specifications may be limited to lower values. It is important to understand that the speed of applications after transfer directly depends on the speed class of your memory card.
It is recommended to use cards marked Class 10, UHS-I or higher, as old and slow drives can cause lags and freezes running from them programs. If you use a card that previously worked on another device, it is best to pre-copy important data on the computer and format it again directly in the smartphone.
⚠️ Warning: The process of formatting the memory card as an internal storage device will completely destroy all the data on it. Be sure to back up photos, documents and music before starting the procedure.
Make sure your Redmi 7 battery is at least 50-60% charged to avoid turning the device off during critical system file writing processes.Put the card into the slot, wait for notifications of finding a new drive, and proceed to the next setup step through the device menu.
Formatting the drive as an internal storage
Modern versions of Android and shells MIUI Adoptable Storage technology that converts the external SD-This is a key moment for anyone who wants to download apps directly to the map or transfer them to existing ones. Without this procedure, the system will treat the drive only as a place to store photos and music, not allowing the installation of programs there.
To activate this feature, go to the smartphone settings. Find the Settings section, then select About Phone or immediately go to Advanced Settings (depending on the version). MIUI The path may vary slightly, sometimes you need to go to the Warehouse. SD-map and click on the formatting button.
The system will offer two use cases: Portable Storage and Internal Storage, and you have to choose the second option, and then you start the encryption and formatting process, which can take a few minutes, and don't interrupt the process and remove the card until the system reports a successful completion of the operation.
☑️ Pre-formatting verification
Once formatted, the system may suggest transferring the data (photos, contacts) to a new drive, which is the best time to release the main memory. If you chose this method, then when installing new apps from Google Play or GetApps, they will by default tend to take up space on the formatted one. SD-map.
Instructions for the portability of installed applications
Even after map formatting, not all applications automatically move to the new drive.Some system services and critical programs must remain in internal memory to ensure the OS runs smoothly. However, custom applications such as games, social networks, and instant messengers can often be moved manually through settings.
To do this, open the Settings menu and find the Apps section. Select All Apps to see the full list of installed software. In the list, find the program you want to move (such as a heavy game or graphics editor) and click on it.
In the app management menu that opens, find the Memory or Storage button. If the app supports portability, it will activate the Change or Move button. Click on it and select yours. SD-The system will start the process of file migration, the duration of which depends on the size of the application.
| Type of application | Possibility of transfer | Impact on speed | Recommendation |
|---|---|---|---|
| System services | Impossible. | Critically. | Keep it in mind. |
| Social media | Partially/completely | Average. | Can we move it? |
| Hard games | Completely. | Depends on the card. | Better move it. |
| Messengers | Only the media. | Low. | Set up inside the application |
Note that after the transfer, the application icon remains on the desktop, but the program files are now physically located on an external medium. If you remove the card, the application will stop running until the drive is returned to its place.
Configuring data storage in applications
Many users mistakenly believe that migrating the app itself automatically redirects all the files it creates to a memory card, which is not always the case, for example, instant messengers like Telegram or WhatsApp have their own settings for saving downloadable media files, which must be changed separately within the programs themselves.
So let's take a sample of a popular messenger, and go to WhatsApp, and you can select Data and Storage, and then you can choose the Save Path. SD-Similar actions are available in camera, voice recorder and browser settings, where you can specify external storage as a priority for downloaded content.
Also worth mentioning is the Cleanup feature in Xiaomi’s standard Security app. Once the apps are ported to the map, this tool can work more efficiently as the main memory is freed from cache. Check this section regularly to delete remnants of deleted programs and temporary files that may take up space even after the transfer.
💡
If the app is unstable after transfer, try moving it back to internal memory. Some programs that require high speed reading data (for example, navigators or online shooters) can slow down on cheap memory cards.
It's important to keep an eye on system notifications. If the memory card gets damaged or deleted, Android may suggest formatting it again the next time you install it, and if you agree to that, you'll lose all the data, so always backup important information to your computer or to the cloud.
Limitations and problems with transfer
Despite the convenience of the technology, users of Xiaomi Redmi 7 may face a number of restrictions dictated by Google’s security policies and the features of specific applications.
Often the transfer button is inactive (grey) or not in the app menu, which means that the developer has coded a ban on working from the external drive, in such cases, only cleaning the cache inside the application or removing unnecessary data, such as downloaded files in messengers, helps.
⚠️ Note: After updating the Android operating system or shell MIUI, all annexes transferred to SD-The card can automatically return to the internal memory, and you have to repeat the transfer procedure again.
Another common problem is slowing down the speed of downloading programs. Smartphone internal memory (especially eMMC or UFS) usually runs faster than most microSD cards. If you notice apps opening longer or crashing, it's a signal that the memory card is not coping with the load or has a low write life.
Why can't some apps be moved?
Alternative ways to free up memory
If standard portability methods fail or the memory card is missing, there are other ways to optimize space on Redmi 7. One effective method is to use cloud storage. Services like Google Photos allow you to store media files in the cloud, leaving only thumbnails on the device, saving gigabytes of space.
Also worth noting are the lighter versions of apps, which are many of the most popular services (Facebook Lite, Messenger Lite, Google Go) that take up much less space and consume less resources, which is ideal for devices with limited memory, and can be found on Google Play by adding the word Lite to the program name.
Remember to periodically clean the Downloads folder. Often users forget about downloaded APK installation files, documents and images that have been in this directory for years. A standard Explorer or Files app will help quickly sort content by size and remove unnecessary ones.
💡
A comprehensive approach to memory cleaning (application port + cloud photos + lightweight versions of programs) allows you to increase the free space on the Xiaomi Redmi 7 up to 70%, significantly extending the comfortable life of the device.
