Cleaning internal memory on a Huawei Android tablet: a complete guide

The internal memory on tablets Huawei (series MediaPad, MatePad, T-series) fills up faster than on smartphones - due to large application files, game caches and automatic updates EMUI. Even if you regularly delete photos, the system may show "Storage Full" due to hidden temporary files or duplicates. In this article we will look at 7 working methods memory clearing, including little-known firmware functions Huaweithat do not require root access.

Feature of tablets Huawei —dividing memory into system partition (where updates and firmware are stored) and user (for your files). Often the problem is not a lack of space, but memory fragmentation or malfunctions F2FS file systemwhich Huawei uses in new models. We will tell you how to diagnose the cause and choose the optimal cleaning method - from manual garbage removal to a deep reset with saving data.

1. Analysis of occupied space: what exactly is occupying memory?

Before clearing memory, you need to understand which files it is being filled. There is a built-in tool for this Huawei there is a built-in tool for this Storage, but it does not always show the full picture. Here's how to conduct an in-depth analysis:

Open Settings → Memory → Storage. Here you will see a diagram with memory distribution by categories: Applications, Images, Video, Audio and Other. Click on each category to see details:

• 📱 Applications: sort by size - often the culprits that fill memory are games (Genshin Impact, Call of Duty Mobile) or social networks (TikTok, Facebook), which cache gigabytes of content.
• 📷 Images: check the folder DCIM/.thumbnails — thumbnails are stored here, which can weigh up to 1–2 GB.
• 🎬 Video: pay attention to the folder Movies —videos from messengers are automatically saved here (WhatsApp, Telegram).
• 🗑️ Other: temporary update files (hw_ota), system log files (log) and cache are hidden here Huawei Mobile Services.

If the built-in analyzer does not show details, install a third-party application Files by Google or SD Maid (available in AppGallery). They can scan deep folderswhere standard tools Huawei do not look, for example:

• 🔍 Folder /data/data —here application data is stored (root access is required for full access).
• 🔄 Folder /cache — system update cache (can weigh up to 500 MB).
• 📦 Folder /Android/obb — additional game files (sometimes remain after deletion games).

⚠️ Attention: If the category "Other" takes up more than 3-4 GB, this may indicate file system damage. In this case, only resetting to factory settings or flashing it via eRecovery.

2. Clearing the application and system cache

Caches are temporary files that applications create to speed up work. Over time, they accumulate and can take up up to 5–10 GB memory. data-i="107">The cache is divided into two types: Huawei cache is divided into two types:

1. Cache of individual applications - cleared manually for each application.
2. System cache - accumulated during updates EMUI and operation services Huawei.

To clear the cache of an individual application:

1. Go to Settings → Applications.
2. Select an application (for example YouTube or Chrome).
3. Click Storage → Clear cache.

For mass clearing the cache of all applications:

1. Open Settings → Memory → Memory cleaning.
2. Select tab Deep cleaning.
3. Tick the boxes opposite Application cache and Residual files.
4. Click Clear (a reboot may be required).

The system cache (Dalvik-cache) is cleared only through recovery mode:

1. Turn off the tablet.
2. Hold Volume up + Power until the logo appears Huawei.
3. In the menu eRecovery select Wipe Cache Partition.
4. Confirm the action and wait for completion.

Close all applications

Connect the tablet to charge (the process may take 5-10 minutes)

Make a backup copy of important data (in case of failure)

Check the free space after cleaning-->

⚠️ Attention: Clearing the cache Huawei Mobile Services (folder com.huawei.hms) may lead to temporary interruptions in the operation of AppGallery and services Huawei ID. After cleaning, restart the tablet and check for updates in Settings → System update.

3. Removing unnecessary applications and their residual files

Many users delete applications, but they residual files remain in memory, for example, after uninstallation Facebook folder /Android/data/com.facebook.katana there may be files weighing up to 1 GB. Here's how to delete them completely:

Method 1: Through standard settings

2. Click on the three dots in the upper right corner and select Show system processes.
3. Find an unnecessary application (for example, Huawei Browser or Petal Maps).
4. Click Delete → Clear data (if the button is active).

Method 2: Using ADB (for advanced users)

Some system applications Huawei cannot be deleted through the menu, but they can be deactivated via ADB (Android Debug Bridge). To do this:

1. Enable Developer mode (click on Build number v Settings → About phone).
2. Activate USB debugging in Settings → System → Developer Mode.
3. Connect the tablet to the PC and run the command:

   adb shell pm uninstall --user 0 com.huawei.browser

   (replace com.huawei.browser with the package of the desired application).

List of system applications that are safe to remove Huawei (do not delete what is not you know!):

adb shell pm list packages | grep "keyword"

After removing system applications via ADB, be sure to run the command adb shell pm compile -m speed -f com.huawei.browser (replace with the package name) to avoid errors the next time you update EMUI.

4. Transferring files to a memory card or cloud

If the internal memory is full, but you do not want to delete files, you can transfer them to microSD or to the cloud. However Huawei has limitations:

• 📱 Starting from EMUI 10, you cannot transfer applications to a memory card (media files only).
• ☁️ Cloud Huawei Cloud gives only 5 GB for free (for extensions need to be paid).
• 🔄 Some applications (for example, WhatsApp) do not allow you to transfer chats to SD.

How to transfer files to microSD:

5. Cleaning hidden folders and temporary files

There are hidden folders that are not displayed in standard Explorer, but can take up gigabytes of memory. They can be found through Huawei There are hidden folders that are not displayed in standard Explorer, but can take up gigabytes of memory. They can be found through Total Commander or FX File Explorer (turn on the display of hidden files in the settings).

Which folders can be cleaned:

• 🗃️ .thumbnails — thumbnails of images and videos (can be deleted completely).
• 🔄 Download —here downloads from browsers and instant messengers accumulate.
• 📥 Android/data — residual files of deleted applications (delete application folders that no longer exist).
• 📦 Android/obb — additional game files (can be deleted if games are deleted).
• 🔧 log — system log files (delete everything except current logs).

How to safely clear these folders:

1. Install FX File Explorer from AppGallery.
2. Enable the display of hidden files in the application settings.
3. Go to the root folder of the storage (/storage/emulated/0/).
4. Delete the contents of the folders from the list above (except Android/data —here delete only folders of deleted applications!).

Clearing the update cache EMUI:

After updating the firmware in the folder /hw_ota temporary files weighing up to 1–2 GB. To delete them:

1. Connect the tablet to the PC via USB (in File transfer mode).
2. Open the folder Internal Storage → hw_ota.
3. Delete all files with the extension .zip or .tmp.

⚠️ Attention: Do not delete files in folders system, vendor or product - this will lead to system crash and will require flashing via eRecovery.

6. Reset to factory settings (Hard Reset)

If none of the methods help, this remains full resetThis will delete all data, but return the tablet to a “clean” state. There are two types of reset: Huawei There are two types of reset:

• 🔄 Soft reset (via settings) - saves some system files.

3. Select Wipe data/factory reset.
4. Confirm the action and wait for completion (tablet will reboot automatically).

What to do after the reset:

• 📱 Do not restore data from the backup copy immediately - first check if the memory problem has recurred.
• 🔄 Update EMUI to the latest version via Settings → System update.
• ☁️ Set up cloud backup (for example, in Google Photos) to avoid data loss in the future.
