Constant notifications that the internal storage is full become a real nightmare for any tablet user. The device starts to work slower, applications crash, and installing new apps becomes impossible without uninstalling old ones. This problem is especially relevant for budget models with limited capacity, which are often enough only for basic needs. internal memory, which are often enough only for basic needs.
Fortunately, the operating system provides users with many built-in tools for managing files. You don't have to be an advanced programmer to restore your tablet to its former agility. In this article we will analyze all the stages of cleaning: from simply deleting unnecessary pictures to deep cleaning of system garbage that has been accumulating in the bowels of the device for years.

Analysis of occupied space and search for memory “eaters”
Before deleting anything, you need to understand what exactly is taking up precious gigabytes. Users are often surprised to find that space is being consumed not by a collection of photos, but by the cache of a popular instant messenger or a forgotten game. Start by checking your storage usage statistics.
Go to the settings of your device and find the section Storage or Memory. Here the system will provide a visual data distribution diagram. Pay attention to the categories "Applications", "Images", "Videos" and "System Files". This is where the main sources of problems are hidden.
Modern shells from Samsung, Xiaomi or Huawei often have built-in analyzers that automatically highlight large files or rarely used applications. If your tablet runs on a “clean” Android, you will have to carry out this audit manually, checking each category sequentially.
- 🔍 Check the "Download" folder - installation APK files and documents that are no longer needed are often accumulated there.
- 📱 Sort apps by size and find those that take up the most space but are rarely used.
- 🎵 Scan your media library for duplicate photos or low-quality videos that you can delete without regret.
Clearing application cache and system data
The fastest way to free up space is deletion cached data. Cache are temporary files that applications create to speed up their work. Over time, they grow to gigantic proportions, especially in browsers, social networks and streaming services.
To clear, go to Settings → Applications. Select a specific application, for example YouTube or Chrome, and click on the "Storage" item. There you will see a "Clear cache" button. It is important not to confuse it with the “Clear data” button, since the second one will delete all your logins, settings and history inside the application.
Many users wonder: is it possible to clear the cache of all applications at once? On older versions Android this function was built into the storage menu. In new versions (starting from Android 11 and higher), Google has removed this feature from the standard interface for the sake of security, so you will have to clean it selectively or use third-party utilities.
⚠️ Attention: Do not use aggressive “cleaners” from the Play Market that promise to speed up the tablet in one click. Often they themselves consume a lot of resources and show intrusive advertising, causing more harm than good.
Clear the cache of your browser and instant messengers (especially Telegram and WhatsApp) regularly, as they accumulate gigabytes of viewed pictures and videos, even if you did not save them.
Removing unnecessary applications and optimizing installed ones
Simply deleting icons from the desktop does not free up memory - it only hides the shortcut. To actually uninstall a app, you need to go to the applications or settings menu. Find software that you have not used for the last three months and mercilessly remove it.
Pay special attention to pre-installed applications (bloatware), which are often included with tablets from manufacturers. Some of them cannot be removed in the standard way, but they can disable. This will hide them from the menu and stop background processes, although they will still continue to take up space.
If you need an application, but it takes up too much space, check if you can move it to a memory card. This feature is not available for all apps and depends on the version Android and developer policy.
Settings → Applications → [Select application] → Storage → Edit → SD memory cardThe table below shows examples of application types and recommendations for them processing:
| Application type | Recommended action | Potential savings |
|---|---|---|
| Games with heavy cache (PUBG, Genshin Impact) | Delete if you do not play; transfer cache to SD | High (2-10 GB) |
| Social networks (VK, Instagram) | Regular clearing of the cache inside the application | Medium (500 MB - 2 GB) |
| Office packages and editors | Leave, check the documents folder | Low |
| Streaming services (Netflix, Spotify) | Delete downloaded content for offline viewing | Medium/High |
Deleting one heavy game can free up more space than clearing the cache of a dozen light utilities. Prioritize the removal of voluminous content.
Working with media files and transferring data to a memory card
Photos and videos are the main consumers of space on tablets, which are often used for entertainment and content consumption. If your device has a slot for microSD cards, this is your lifeline.
The ideal strategy is to set up automatic saving of new photos and videos directly to the memory card. Go to the camera settings and find the "Save location" item. Change it from "Internal memory" to "SD card".
For existing files, use a file manager. Select the folders DCIM, Pictures, Download and move them to external media. Be careful: when moving, make sure that the memory card is working and has sufficient capacity.
- 📂 Use a file manager Files by Google to safely move large amounts of data.
- ☁️ Set up synchronization with cloud services (Google Photos, Yandex.Disk) to store originals in cloud, and leave only thumbnails on the tablet.
- 🗑️ Do not forget to empty the trash in the gallery after deleting files - often deleted photos continue to take up space for another 30 days.
⚠️ Attention: When formatting a memory card as internal storage (Adoptable Storage function), all data on it will be destroyed and it will be encrypted for work only with this specific tablet.
What is Adoptable Storage?
This is an Android feature that allows you to combine internal memory and a microSD card into a single space. The system sees them as one disk. This is convenient, but if the card fails, the data may be lost forever, and transferring the card to another device will become impossible without formatting.
Cleaning messengers: Telegram and WhatsApp
Messengers have become full-fledged media harvesters. By default, automatic downloading of all received photos and videos is configured. Over the course of a year of active correspondence in group chats, more than 10-20 GB of garbage can accumulate. Telegram And WhatsApp By default, automatic downloading of all received photos and videos is configured. Over the course of a year of active correspondence in group chats, more than 10-20 GB of garbage can accumulate.
There is an excellent built-in memory management function. Go to Telegram There is a great built-in memory management feature. Go to Settings → Data and memory → Memory usage. There you can see how much space the cache and downloaded files are taking up. Click "Clear Telegram cache."
Moreover, in the Telegram settings you can set an automatic timer for clearing the cache. For example, configure the deletion of downloaded files if they have not been accessed for more than 3 days. This will allow you to use all the functions of the messenger without filling up the tablet's memory.
Telegram: Settings → Data and memory → Auto-delete media → 3 daysIn WhatsApp the situation is a little more complicated. You need to go to Settings → Data and storage → Storage management. Here the application will show the chats that take up the most space. You can selectively delete media files from specific conversations without deleting the conversation itself.

Radical measures: Reset to factory settings
If None of the above methods helped, and the tablet still indicates that there is not enough space, perhaps the problem lies in deep system errors or file system fragmentation. In this case, a full reset helps.
Factory Reset (reset to factory settings) will delete absolutely all data from the device, returning it to the “as from the store” state. This is guaranteed to free up all user memory and remove viruses or erroneous system files.
Before performing this procedure, it is critical to make a backup copy of all important data: contacts, photos, documents. After the reset, you can restore them from your Google account or from a memory card.
⚠️ Attention: Before resetting, make sure that the tablet is charged at least 50-60%. Turning off the power during the flashing process may cause the device to turn into a “brick” and stop turning on.
The reset process usually looks like this: Settings → System → Reset settings → Delete all data (factory reset). Confirm the action by entering your PIN code or pattern and wait for the process to complete, which may take from 5 to 15 minutes.
Resetting to factory settings is a last resort. Use it only when other methods have been exhausted and you are ready to spend time setting up the tablet again.
Frequently asked questions (FAQ)
Why is there no space freed up after deleting files?
Most likely, the files were moved to the trash inside the gallery or file manager. Check your Trash folder and empty it. It is also possible that the application that you deleted left behind cached folders in the shared memory that need to be deleted manually through the file manager.
Is it possible to delete system applications to free up space?
Without superuser rights (Root), you cannot delete system applications. Attempts to do this via ADB may result in system instability or an endless reboot (bootloop). It is better to simply disable unnecessary system apps in the settings.
How to clear memory if the tablet is slow and does not allow you to enter the settings?
Try to boot into safe mode (usually this is done by long pressing the power button on the reboot menu screen). In this mode, third-party applications will not start, and you can remove the culprit of the brakes. If it doesn’t help, use Recovery mode to reset the settings.
Does filling the memory affect the speed of the tablet?
Yes, directly. The operating system Android uses part of the free internal memory as virtual RAM (swap/zRAM). If the space is full to capacity, the system has no place to place temporary data, which leads to severe freezes and application crashes.
Will applications like Clean Master help?
In most cases, they give only a temporary effect, deleting the same cache that can be cleared using standard means. Often such applications themselves run in the background, consume the battery and display advertisements. Built-in Android tools now cope with this task no worse.
