Transferring applications to a memory card in Huawei smartphones: a complete guide

Owners of smartphones Huawei with limited internal memory are often faced with the need to make room for new applications, photos or system updates. One of the effective ways to solve this problem is transferring installed applications to a memory card microSD. However, not all models Huawei support this function out of the box, and in some cases the procedure requires additional settings or even root access.

In this article we will figure out how to correctly transfer applications to an external drive, what restrictions exist for different versions. EMUI (Huawei proprietary shell), and what to do if standard methods do not work. You will also learn which applications can be transferred without risking system stability, and which are better left in the internal memory. We will pay special attention to the nuances of working with Huawei Mate, P-series and budget models - their capabilities may differ significantly.

Which Huawei smartphones support transferring applications to an SD card

The functionality of transferring applications to an external memory card depends on the version EMUI and hardware limitations of the specific models. Most devices based Android 6.0–8.1 (EMUI 4-8) support this option out of the box, while in newer versions (EMUI 9+ on Android 9-13) it may be blocked or hidden.

Here are the key points to consider:

• 📱 Models before 2018 (Huawei P10, Mate 9, Nova 2 etc.) - usually support transfer through standard settings.
• 🚫 Models 2019-2023 (P30, Mate 20, Nova 5T and newer) - often lack this feature in EMUI 9-13 due to Google and Huawei security policies.
• ⚠️ Budget series (Y6, Y7, Y9) - may support porting, but with restrictions (for example, only for part applications).
• 🔧 Devices with root access - allow you to force applications to be transferred through ADB or third-party utilities.

To accurately determine whether your smartphone supports transfer, check version EMUI in section Settings → About phone. If the shell version 9.0 or later, most likely, the standard transfer will not be available - alternative methods will be required.

Preparing the memory card: formatting and selecting the correct standard

Before transferring applications, you must properly prepare the microSDcard. Not all memory cards are suitable for this task - not only the volume is important, but also speed class and file system format.

Memory card requirements for transferring applications:

• 📏 Minimum volume: 16 GB (recommended 32 GB or more for comfortable work).
• ⚡ Speed class: UHS-I (U1/U3) or Class 10 —slow cards can cause lags.
• 🔄 Format: exFAT or FAT32 (but not NTFSwhich Android does not support).
• 🔒 Manufacturer: Brands are preferred SanDisk, Samsung, Kingston —cheap no-name cards often fake speed characteristics.

If the card is new, it needs to be formatted directly in the smartphone:

1. Insert the card into the slot (with the phone turned off, if required).
2. Go to Settings → Memory → Memory card.
3. Select Format as internal memory (if available) or Format.
4. Confirm the action - all data on the card will be deleted!

Standard transfer of applications through EMUI settings (for supported models)

If your Huawei supports transfer of applications, the procedure takes only a few minutes. The main thing is to follow the instructions and not transfer system utilities that can disrupt the operation of the phone.

Step-by-step guide:

1. Open Settings → Applications.
2. Select the application you want to transfer (for example, Facebook or Spotify).
3. Click on Storage.
4. If the option is available, you will see a button Edit or Move to SD card.
5. Confirm the transfer and wait for the process to complete (this may take up to several minutes).

Important: not all applications can be transferred. For example, system utilities (Google Play Services, Huawei Mobile Services) and some games with anti-piracy protection (PUBG Mobile, Genshin Impact) block this feature.

Alternative transfer methods for EMUI 9 and newer

In modern versions EMUI (9.0–13.0) standard application transfer is often disabled. This is due to security policy Huawei i Google, which considers that storing applications on SD cards increases the risk of failures and vulnerabilities. However, there are workarounds:

Method 1: Using ADB (without root access)

Using Android Debug Bridge (ADB) you can force transfer applications, even if there is no such option in the settings. To do this:

1. Enable USB debugging in Settings → About phone → Number assembly (press 7 times, then return to Settings → System → For developers).
2. Connect your phone to the PC and install ADB-tools.
3. Run the command in the terminal:

   adb shell pm set-install-location 2

   This will force the system to install new applications on the SD card by default.

4. To transfer already installed applications, use:

   adb shell pm move-package com.example.app /sdcard

   (replace com.example.app with the actual application package).

Method 2: Applications for forced transfer

There are utilities that automate the process, but they require root access:

• 🔧 App2SD - a classic solution that supports cache and data transfer.
• 📱 Link2SD - creates symbolic links, saving space in internal memory.
• ⚠️ FolderMount - transfers only parts of applications (for example, game cache).

Risks of using ADB and root access

Incorrect ADB commands can lead to application crashes or even bricking of the phone. root access void the warranty and increase vulnerability to viruses. Use these methods only if you understand the consequences!

Which applications can be transferred and which cannot

Not all applications work equally well from external memory. Transferring some may lead to errors, crashes or even data loss. Here are the basic rules:

Application type	Can I transfer?	Risks
Social networks (VK, Telegram)	✅ Yes	Minimal (rare lags are possible)
Games (Clash of Clans, Brawl Stars)	⚠️ Partially	Game cache may not transfer, crashes are possible
System utilities (Google Play, Huawei AppGallery)	❌ No	Critical system failures
Messengers (WhatsApp, Signal)	✅ Yes (but it is better to leave media files in the internal memory)	Loss of chat history when extracting cards
Offline cards (Google Maps, Yandex.Maps)	✅ Yes	No risks

Critical information: Applications with payment functions (bank clients, wallets) NEVER should not be transferred to an SD card. This may lead to account blocking due to suspicions of hacking.

Frequent errors and their solutions

When transferring applications, users often encounter problems. Here are the most common errors and ways to resolve them:

• 🔄 "Not enough space on the card" —even if the card is empty, EMUI can reserve space for system needs. Solution: reformat the card as internal memory.
• 🚫 "The transfer button is inactive" —this means that the application does not support transfer or the card is formatted as portable storage. Solution: check the card format or use ADB.
• ⚠️ "The application does not start after transfer" - perhaps not all files were transferred. Solution: clear the application cache or transfer it back.
• 📵 "The phone does not see the card after transfer" —if the card was used as internal memory, it cannot be removed without resetting the phone. Solution: make a backup copy of the data before extracting.

Optimizing application performance after transfer

Moving applications to an SD card is only half the battle. For the system to work stably, you need to perform several additional steps:

1. Clear the cache transferred applications to Settings → Applications → Storage → Clear cache.
2. Disable automatic updating for migrated applications in Google Playto avoid failures.
3. Check the health of the card regularly memory through applications like SD Card Tester - degraded cards can slow down the work.
4. Do not fill the card more than 80% —this reduces its speed and increases the risk of data loss.

If you notice that the phone has become slower after the transfer, try returning the most resource-intensive applications (for example, games) back to the internal memory. It is also worth considering the option of purchasing a smartphone with a large amount of built-in memory if you actively use many applications.

FAQ: Answers to frequently asked questions

Can I transfer WhatsApp to a memory card without losing chats?

Technically yes, but not recommended. When transferring WhatsApp to an SD card, chat history and media files may become corrupted, especially if the card suddenly turns off. It is better to use the built-in backup function in Google Drive and clear the cache manually.

Why did it start to slow down after transferring the game to the card?

Most likely, your microSDcard has low read/write speed. Games require fast access to data, and even class cards U1 may not cope with the load. Solution: transfer the game back or buy a class card. inoperative. The only safe way is to disable unnecessary system apps through U3 or A2.

Is it possible to transfer Huawei system apps (such as AppGallery)?

No, this will lead to critical system failures. System applications are strictly tied to the internal memory and transferring them can make the phone inoperable. The only safe way is to disable unnecessary system apps through Settings → Applications.

What to do if the phone does not see the card after formatting as internal memory?

This is a known problem for some models Huawei. Try:

1. Remove the card and insert it back.
2. Restart the phone.
3. If that doesn’t help, reset the settings via Settings → System → Reset (data on the phone will be deleted!).
