Smartphone owners Huawei i Honor often face a lack of built-in memory, especially on budget models with 32 or 64 GB of storage. The accumulation of photos, videos and the installation of modern “heavy” games quickly fill the available space, slowing down the device. A solution to this problem can be to use a microSD memory card as additional storage for apps.
Unfortunately, modern versions of the operating system Android, in combination with a proprietary shell EMUI or Magic UI, impose certain limitations. Google developers recommend storing data on an internal drive to ensure maximum speed and security. However, with a competent approach and compliance with technical nuances, memory expansion is still possible. Huawei It is recommended to store data on an internal drive to ensure maximum speed and security. However, with a competent approach and compliance with technical nuances, memory expansion is still possible.
In this article we will look at all the available ways to move applications to external media. You will learn how to format a card in “internal memory” mode, what hidden settings need to be activated through the developer menu, and why some apps categorically refuse to move to SD card.
Preparing a memory card and selecting a speed class
Before proceeding with the system settings, you need to make sure the quality of the drive itself. For the correct operation of applications, especially those that require constant access to the disk (messengers, navigators, games), the speed of reading and writing the card plays a critical role. A slow memory card can turn your smartphone into a “slow” device.
It is recommended to use standard cards UHS-I or UHS-II with a speed class marking of at least Class 10. Ideally, if the card has the designation A1 or A2 (Application Performance Class), this guarantees optimization for running applications. Using old class 4 or 6 cards may cause the interface to freeze and errors when opening apps.
Insert the card into the slot of your smartphone Huawei. It is usually located on the side and requires the use of a special paperclip to remove the tray. Make sure that the card is detected correctly by the system by going to the storage settings. If the system prompts you to select a use mode immediately after insertion, do not rush to agree to the standard option, as we may need deeper settings.
When buying a memory card, pay attention to the warranty and brand. SanDisk, Samsung and Kingston usually show stable results in conjunction with Android smartphones.
⚠️ Attention: All data on the memory card will be completely deleted during the formatting process to suit the needs of the system. Be sure to save important photos and documents on your computer or in the cloud before starting the procedure.
Activating developer mode for advanced settings
In the standard settings menu EMUI the option to force application transfer is often hidden or missing. To access advanced memory management features, you must enable the developer mode. This is a safe procedure that does not void the warranty, but requires care when changing parameters.
To enable the mode, go to section Settings and scroll to the bottom of the list to item About phone. Find the line Build number and quickly click on it 7 times in a row. After several clicks, the system will ask you to enter your PIN code or screen unlock pattern.
After successfully entering the code, a pop-up notification will appear indicating that you have become a developer. Now in the main settings menu, usually in the section System or immediately in the list of general settings, a new item will appear For developers. This is where the keys to controlling the behavior of applications and storage are located.
Inside the developer menu, we are interested in the option related to adaptive storage. Find the item Force to allow the transfer of applications (Force allow apps on external) and activate the switch. This command gives the system permission to ignore the internal restrictions of some apps, allowing them to be installed on external media, even if the developer did not intend this.
Formatting the card as internal memory (Adoptable Storage)
The most effective way to integrate a memory card is to format it as internal storage. In this mode, the system Android encrypts the card and combines its volume with the main memory of the phone, creating a single space. Applications will be installed there automatically if the main partition is full.
However, on many new models Huawei this function is software blocked by the manufacturer. If after inserting the card into the menu Storage there is no option "Use as internal storage", you will have to act through the computer. You will need to connect your smartphone to your PC in USB debugging mode and use console commands ADB.
First, make sure that USB debugging is enabled in the same developer menu that we activated earlier. Connect the phone to the computer, open the command line on the PC and enter the command to enter the device shell:
adb shellAfter successful connection, enter the command to display a list of all drives to find out the ID of your memory card:
sm list-disksThe system will give a response like disk:179,64 or a similar numeric value. Remember this ID, it will be needed for the next command, which will turn the card into internal memory. Be extremely careful, as an error in numbers can lead to formatting the wrong partition.
☑️ Preparing for formatting via ADB
Transfer installed applications through settings
If automatic transfer did not work or you are using the card in portable storage mode, you can try moving the apps manually. This method does not work for all applications, since developers can hardcode the installation path in the app code, but for many utilities it is quite effective.
Go to the Applications section in the smartphone settings. Select the app you are interested in from the list. If transfer is possible, a button Change or tab Storage with the option to change location will be active in the application management menu.
Click on the button and select SD card. The system will begin the data migration process. The operation time depends on the size of the application and the speed of your memory card. During the transfer process, the application icon may become inactive; it is not recommended to interrupt the process.
| Application type | Probability of transfer | Impact on speed | Recommendation |
|---|---|---|---|
| Games with cache | High | Average | Can be transferred |
| Messengers | Low | High | Keep in memory |
| Social networks | Average | Average | Test individually |
| System utilities | Prohibited | Critical | Do not transfer |
Please note that widgets and some application functions may stop working correctly after moving to external media. This is due to the fact that the system mounts the SD card a little later than the main interface loads, and the application may not find its resources at the right time.
Why is the "Move" button inactive?
If the button is gray or missing, then the application developer has prohibited installation on external media at the app manifest level. This can only be circumvented by using special modified versions of applications or root access, which is not recommended for ordinary users.
Features of working with cache and data on Huawei
Even if the application itself is installed on a memory card, a significant part of its data, including cache and temporary files, often remains in the internal storage. This is an architectural feature Androidaimed at performance. On smartphones Huawei This logic is followed especially strictly to ensure smooth operation of the shell.
To free up space, it is useful to manually clear the cache of heavy applications. Go to the settings of a specific application, select Memory and press Clear cache. This is safe and will not delete your logins or correspondence, but will free up hundreds of megabytes in the internal partition.
Some file managers allow you to transfer folders with data (for example, a cache from games located in a folder Android/obb) manually. However, after updating the application, this data may be overwritten or ignored if access paths change. Use this method only as a last resort when other options have been exhausted.
⚠️ Warning: Do not attempt to transfer Google system applications or services Huawei Mobile Services. Their movement can lead to unstable operation of the smartphone, synchronization failures, and even cyclic rebooting of the device.
Possible problems and ways to solve them
When using a smartphone with applications on the SD card, you may encounter a number of specific problems. The most common of these is the sudden disappearance of app icons or the error message “The application is not installed.” This often happens if the contact of the card is broken or the system was unable to quickly mount it upon boot.
If applications begin to run slowly or crash, try removing the card, inserting it into the computer and checking for file system errors. In Windows this is done through the disk properties, in macOS - through Disk Utility. Sometimes simply reformatting the card back to portable mode and re-configuring it solves the problem.
It is also worth considering that memory cards have a limited recording resource. Active use of applications that constantly record logs and caches can quickly damage the card compared to regular photo storage. Monitor the condition of the drive and make backup copies of important data.
Using a memory card as internal storage speeds up the filling of its recording resource, so choose only high-quality models with a high reliability rating.
In rare cases, after updating the firmware EMUI developer settings may be reset and the forced transfer function is disabled. If you notice that new applications are no longer installed on the card, check the developer menu again and activate the desired toggle switch again.
Frequently asked questions (FAQ)
Is it possible to transfer WhatsApp to an SD card on Huawei?
Officially, you cannot transfer the WhatsApp application itself to a memory card, since how developers prohibit this to ensure the security and stability of the messenger. However, in the settings of WhatsApp itself, you can change the path for saving media files (photos and videos) to the memory card, which will free up significant space in the internal storage.
What happens if you remove the SD card with installed applications?
All applications installed on the card will stop running, and their icons may disappear from the desktop or become gray. Data from these apps will no longer be available until the card is reinserted. The system will assume that these applications have been deleted until the media is connected and recognized again.
Why does the game run slower after the transfer?
The random block reading speed of most microSD cards is lower than that of the built-in flash memory of a smartphone. Games that require fast loading of textures and levels may experience delays (freezes). To minimize this effect, use cards with markings A2that are specially optimized for working with applications.
Are the settings reset when formatting the card for internal memory?
No, the settings of the phone itself are not reset. However, the memory card will be completely cleared. If you decide to return the card to portable storage mode or insert it into another device, it will have to be formatted again and all data on it will be lost.
