Owners of modern smartphones Honor often encounter a situation where the built-in storage fills up faster than expected. High-resolution photos, 4K videos, and heavy apps take up gigabytes, causing the system to run slower. Fortunately, most of the brand’s models support expansion of physical volume through cards microSD. This solution allows you to unload the system partition and save important files without having to delete your favorite games or media.
The procedure for transferring data varies depending on the version of the operating system Magic UI or EMUIinstalled on your device. In new firmware, Google has limited the ability to fully merge memory, but the functionality for transferring media files and some applications remains available. Proper configuration of the memory card turns it into a full-fledged extension of the internal storage, ensuring uninterrupted operation of the gadget even when actively shooting video.
Before you begin manipulating the file system, you need to make sure that the accessory is compatible and that it is working correctly. Improper media preparation may result in data loss or read errors. In this material we will analyze in detail all the stages: from choosing a suitable card to the intricacies of setting up adaptive storage, which integrates external memory into the system structure.
Selecting and preparing a memory card for Honor
The success of the operation directly depends on the quality of the drive used. Cheap cards from unknown brands often have actual writing speeds lower than advertised, which causes interface freezes and failures when saving photos. For smartphones Honor it is recommended to use class cards UHS-I or UHS-II with a speed marking of at least Class 10. This will ensure fast loading of applications and smooth video recording.
Before installing it in the phone slot, the card must be formatted. This action will completely clear the media, removing all old files, so copy important data to your computer in advance. Formatting creates a new file system compatible with Android and checks sectors for physical damage. Ignoring this step may result in the phone seeing the card, but not being able to write a single byte of information to it.
⚠️ Attention: Formatting a memory card inside a smartphone will destroy all data on it. Make sure that you have backed up important files before starting the procedure.
Insert the card into the special tray, following the orientation of the contacts, usually shown on the tray itself or in the instructions for the device. Once connected, the system will notify you that a new drive has been detected. At this stage, it is important to choose the correct operating mode: use as a portable storage device or as internal memory. The first option is suitable for storing photos and music, the second is for installing applications.
Use memory cards up to 256 GB for maximum compatibility with older Honor models, although new flagships support both 512 GB and 1 TB.
Configuring the card as internal storage (Adoptable Storage)
A feature known as Adoptable Storageallows the Android system to treat the memory card as part of the internal drive. This means that applications and their data can be installed directly onto external media, freeing up space on the main partition. However, it is worth noting that in recent versions of the shell Magic UI manufacturers sometimes hide this option to prevent performance degradation when using slow cards.
To activate this mode, go to the settings menu. Find the section Storage or Memory. If the card is detected correctly, you will see it in the list of available drives. Click on the card name to open an additional control menu. Here you should look for the item responsible for changing the type of drive usage.
- 🔍 Go to
Settings→System and updates→Memory. - 💾 Select your card SD from the list of storage devices.
- ⚙️ Click on the three dots in the upper corner or the menu button to bring up the settings.
- 🔄 Select an item
Use as internal storageorFormat as internal memory.
The system will warn that the card will be encrypted and linked specifically to this phone. After confirmation, the process of formatting and data migration will begin. This may take several minutes depending on the size of the card. Upon completion, the system will offer to transfer existing data from the old drive to the new one, which is highly recommended to immediately free up space.
Why might the option be missing?
Some Honor models block the Adoptable Storage function at the firmware level if the card manufacturer is not certified by Google or if the write speed is below a certain threshold. In this case, only manual file transfer will help.
Manual transfer of photos and videos through the Gallery
The most common scenario for using external memory is storing media content. Built-in tools Honor make it easy to move large amounts of photos and videos without connecting to a computer. This method is safe and does not require receiving root access or complex system setup. It is ideal for users who want to maintain the performance of the phone while leaving system files on the fast built-in storage.
Open the standard application Gallery. Select albums or individual photos that take up a lot of space. Usually these are folders Camera, Screenshots or downloaded videos from instant messengers. Once highlighted, click on the menu button (three dots or the "more" icon) and select the move function. The system will prompt you to select the target directory on the memory card.
⚠️ Attention: When moving files through the standard gallery, make sure that the process is not interrupted. Removing the card during copying may damage the files and make them unreadable.
An alternative method is to use the built-in file manager Files. Go to section Internal memory, find folder DCIM or Pictures. Select the required elements, select the option Move or Copy, then go to the section SD card and paste them into the appropriate folder. This approach gives more control over the directory structure.

Transferring applications to the memory card
The issue of installing apps on external media remains one of the most difficult in the Android ecosystem. Starting with Android 6.0, this feature was limited to app developers. Many popular apps, such as instant messengers or banking clients, for reasons of security and stability, prohibit installation on an SD card. However, some applications still support this function.
To check the transferability, go to the phone settings via path Applications → Applications. Select the app you are interested in from the list. If the developer has allowed movement, the button Move to SD card will be active. Otherwise, it will be inactive (grayed out), and you will not be able to change the installation location using standard means.
| Application type | Possibility transfer | Recommendation |
|---|---|---|
| Games with cache | Partially (cache) | Transfer the cache through a file manager |
| Social networks | Rarely | Leave in internal memory for speed |
| Office apps | Often | You can safely move to SD |
| System utilities | Prohibited | Do not move to avoid crashes |
There is a method for moving the cache of heavy games manually. Find the folder Android/obb in the internal memory. Copy the folder with the game data (usually starting with com.) to a similar directory on the memory card. Then delete the original from the internal memory. The game will continue to work, loading resources from external media, which significantly saves space.
Setting up default data saving
In order not to transfer files manually every time, it is advisable to set up automatic saving of new data to the memory card. This applies primarily to photographs and videos. In the camera settings of most smartphones Honor there is a switch responsible for priority storage. Activating it ensures that all new pictures will immediately go to the external drive.
Open the application Camera and click on the settings icon (gear) in the corner of the screen. Scroll down the list of options to the Save priority or Storagesection. Change the value from Internal memory to SD card. Now, when shooting in high resolution or recording 4K video, the free space of the main disk will not be consumed.
A similar setting can be made for the voice recorder and some browsers. InDownload in the internal storage.
Automatically setting the camera to save to an SD card is the most effective way to prevent memory overflow in the future without unnecessary actions.
Possible problems and solutions solutions
Sometimes users encounter a situation where the phone stops seeing the card or displays a mounting error. This may be caused by oxidation of the contacts, a software glitch, or file system corruption. First of all, try rebooting your device. If this does not help, remove the card, wipe the contacts with a soft eraser or alcohol wipe and insert it back until it clicks.
If the system says “Damaged” or requires formatting, but you cannot lose data, try connecting the card to the computer via a card reader. Run a disk scan using Windows (disk properties → service → check). This often allows you to correct logical errors without losing information. After correcting the errors, reinsert the card into the phone.
⚠️ Attention: If the phone constantly loses the memory card after formatting, it is possible that the phone slot itself has a mechanical defect or the card is not compatible with the supply voltage. Try a different drive for diagnostics.
In rare cases, resetting the network settings or completely resetting the phone to factory settings helps. Before doing this, be sure to back up all your data. Also make sure that your firmware Honor is updated to the latest version, as manufacturers often release patches that correct errors in working with external drives.
What to do if the card is detected as empty?
This is a common symptom of a partition table failure. Try formatting the card on your PC to the exFAT file system if the volume is more than 32 GB, or FAT32 for smaller volumes, then insert it into the phone again.
Frequently asked questions (FAQ)
Can I transfer WhatsApp to a memory card on Honor?
Completely transfer it yourself The WhatsApp app on a memory card is usually not possible due to Android security restrictions. However, you can transfer media files (photos, videos, voice messages). To do this, in the WhatsApp settings, select Data storage → WhatsApp folder and change the save path to an SD card (if the version supports it) or manually move the folder WhatsApp/Media via the file manager.
Why do they run slower after transferring applications?
The speed of applications depends on the read/write speed of the memory card. Even Class 10 cards are often inferior in speed to the phone's built-in flash memory (UFS 2.1/3.1). When running a heavy application from a slow card, the system spends more time loading resources, which causes delays. For games and frequently used apps, it is better to leave internal memory.
Will applications work on the card if you insert it into another phone?
No, if you used the “Internal Storage” mode (Adoptable Storage). In this mode, the card is encrypted with a unique device-specific key. When installed in another phone, the system will require formatting, as it will not be able to decrypt the data. To transfer data between devices, use the "Portable storage" mode.
How to find the real speed of my memory card?
Download a speed test application from Google Play, for example A1 SD Bench or CPU-Z. Run a read-write test. For comfortable operation of applications, the writing speed should be at least 20-30 MB/s, and the reading speed should be above 60 MB/s. If the performance is significantly lower, it is better to replace the card with a more productive one.
Is it possible to divide the card into two sections (for files and applications)?
This cannot be done using standard Android tools. The system sees the map as a single whole. Partitioning is only possible if you have root access and use specialized utilities like Link2SD, which create a second hidden partition. However, this method is difficult for the average user and can lead to unstable operation of the system when updating the firmware.
