Modern smartphones Samsung Galaxy have enormous capabilities, but over time their internal memory inevitably fills up. Users often encounter notifications that the storage is almost fullwhich leads to system slowdowns, problems installing updates, and the inability to take new pictures. This problem is relevant both for budget models of the series Galaxy Aand for flagships Galaxy S, since the amount of content created daily is growing exponentially.
Cleaning memory on devices running the shell One UI has become more intuitive thanks to built-in optimization tools, but many owners still rely on third-party applications, which often only create additional load on the processor. In this article we will analyze in detail the standard methods of freeing up space, which are the safest and most effective for the ecosystem Android. You will learn how to find hidden files, delete unnecessary application caches, and intelligently manage media files without losing important data.
You should not ignore regular device maintenance, as a full drive directly affects the speed of data writing and the overall responsiveness of the interface. We'll look at not only basic cleaning, but also advanced techniques for working with folders, which often become a graveyard of forgotten files. Follow our recommendations to restore your smartphone to its former performance. DCIM And Download, which often become a graveyard of forgotten files. Follow our recommendations to restore your smartphone to its former performance.
Diagnostics of memory fullness using built-in tools
Before you start deleting files, you need to understand exactly what is taking up precious space. The operating system Android on smartphones Samsung provides a powerful analytical tool, which can be accessed through the settings menu. Go to section Settings → Device maintenance → Memoryto see a detailed breakdown by category. Here the system automatically classifies data into applications, images, videos, audio and documents, which allows you to immediately identify the main “consumer” of resources.
Visualization in the form of a color chart helps you quickly navigate: if the sector Applications occupies the lion's share, the problem may hide in instant messengers or games with heavy caches. Users often do not suspect that a regular messenger can take up several gigabytes due to automatically saved photos and videos from chats. Analyzing these statistics is the first step towards proper optimization, allowing you to avoid deleting system-important files.
Pay attention to the “Other” or “System Data” section, which sometimes bloats to incomprehensible proportions. This may be a result of applications shutting down incorrectly or temporary update files accumulating. In such cases, standard cleaning may not work immediately, and a deeper intervention into the file structure will be required, which we will discuss in the following sections. Accurate diagnostics saves time and prevents chaotic deletion of necessary information.
⚠️ Attention: If the volume of the “System Data” partition exceeds 10-15 GB for no apparent reason, this may indicate an error in the file system or a failure after a firmware update. In this case, it is recommended to create a backup copy and reset the settings to factory settings.
Using the built-in memory optimizer
The company Samsung has integrated into the shell One UI a special maintenance module that automatically monitors the state of memory and suggests actions to free it. To start manual optimization, just open the application Settings and select item Device maintenance. Pressing the button Optimize now starts a scan, during which the system closes processes running in the background, deletes temporary files and clears the cache of rarely used apps.
This tool is especially useful for users who do not want to dive deeply into file system settings. Algorithms Device Care safely delete files remaining after uninstallation of applications, and also clear browser download folders of old installation packages .apk. However, it is worth understanding that automatic cleaning does not always affect large media files or the cache of social networks, since the system considers them user data.
For more fine-tuning, you can go to the advanced memory management menu inside the maintenance section. A function Auto Cleanis available here, which can be configured to run weekly or monthly. Activating this option ensures that your phone will regularly get rid of digital junk without your direct participation, maintaining a stable interface speed.
Enable the "Auto Clean" function in the device maintenance settings so that your smartphone automatically deletes unnecessary files once a week, without requiring your intervention.
It is important to note that the built-in optimizer does not delete your personal photos, contacts or documents unless they are clearly duplicates or corrupted. This makes the method safe for daily use. Regular use of this tool extends the life of the drive by reducing the number of rewrite cycles in full memory cells.
Deep cleaning of application and data caches
The largest amount of hidden garbage is usually generated by social networks, video services and navigation applications. Cache is temporary data that speeds up the loading of content, but over time it can grow to gigantic proportions. To clear the cache of a specific application, follow the path Settings → Applications, select the desired app (for example, YouTube or Instagram) and click on the section Memory. Here you will see two buttons: “Clear cache” and “Clear data”.
Using the function Clear cache is a safe procedure that deletes only temporary files without affecting your logins, passwords and settings inside the application. At the same time, the button Clear data returns the application to the state immediately after installation, deleting all your personal correspondence, saved cards and authorization. Be extremely careful when using the second option, using it only if the application is not working correctly or you want to completely reset its settings.
- 🗑️ Messengers: In WhatsApp and Telegram, the cache can take up tens of gigabytes due to the videos you have watched. Clear it through the settings of the application itself in the “Data and Storage” section.
- 🌍 Browsers: Chrome and Samsung Internet accumulate history and cookies. Regular cleaning through the browser menu frees up space and increases privacy.
- 📺 Streaming services: Applications like Netflix or Spotify save covers and video clips. Their cache can be safely deleted if you do not use offline mode.
Particular attention should be paid to map applications, such as Google Maps or Yandex.Mapsthat save huge amounts of data for offline navigation. If you rarely use maps without the Internet, check the downloaded maps section and delete regions that you no longer need. This action can instantly free up several gigabytes of space, which is critical for devices with a small amount of built-in memory.
☑️ Monthly memory hygiene
⚠️ Attention: Clearing app data will delete all your correspondence and settings within it. Make sure you have a backup of important chats before clicking the "Clear data" button.
Manage media files and remove duplicates
Photos and videos are the main consumers of space on any smartphone. Modern cameras Samsung record in high definition, and one minute of video in this format 4K can take up to 500 MB of memory. To effectively manage your media library, use the built-in application Gallery, which has a search function for similar and duplicate images. This option is often hidden in the recommendations menu or in the "Tips" section, where AI algorithms suggest deleting unsuccessful shots.
It is also worth checking the folder DCIM/.thumbnails, where thumbnails of your photos are stored. Sometimes this hidden folder grows to an exorbitant size, especially if you have thousands of pictures in your gallery. Clearing this directory through the file manager is safe, since the system will recreate the thumbnails automatically the next time you open the gallery, but this will take some time and processor resources.
Video files should be analyzed for length and relevance. Often, users forget to delete long screen recordings or bad videos taken in a hurry. Sorting files by size in the file manager My files allows you to quickly find the heaviest objects and decide whether to delete them or move them to cloud storage.
How to find hidden video files?
In the file manager, turn on display hidden files in the menu settings (three dots). Often forgotten videos can be located in messenger folders, for example, WhatsApp/Media/WhatsApp Video, which are not always displayed in the general gallery.
Don't forget about the trash can in the Gallery application. Deleted photos do not disappear forever immediately, but are moved to the trash, where they are stored for another 30 days, continuing to take up space. To instantly free up space, you need to go to the trash menu and select the option Clean up. This action is irreversible, so make sure that you really want to delete these files permanently.
Working with the Downloads folder and third-party files
The (Downloads) folder often turns into a digital landfill, where installation files accumulate over the years application files, PDF documents, presentations and forgotten pictures from the Internet. Many users download files for one-time use and forget about them. Regular audit of this directory through the app Download (Downloads) often turns into a digital landfill, where application installation files, PDF documents, presentations and forgotten images from the Internet accumulate over the years. Many users download files for one-time use and forget about them. Regular audit of this directory through the app My files can free up a significant amount of memory. Sort files by date to find the oldest items that are most likely no longer needed.
Installation files are a special category. .apk. After installing the application, this file becomes useless garbage, but continues to be in memory. The built-in storage analyzer usually highlights such files, suggesting they should be deleted. If you use third-party file managers, pay attention to the file extension: everything that ends with .apk and is not the current version of the app you need can be mercilessly deleted.
| File type | Extension | Recommendation | Where to look |
|---|---|---|---|
| Application installer | .apk | Delete after installation | Download folder |
| Temporary logs | .log, .tmp | Safe deletion | Root folder, Android/data |
| Archives | .zip, .rar | Check contents | Folder Download, Documents |
| Text documents | .txt, .doc | Move to cloud | Documents |
Also check the folders created by third-party applications in the root of the internal memory. Often photo editing apps, document scanners or voice recorders create their own directories to save their work. If you have not used any specific software for a long time, you can delete the corresponding folder entirely. This action will not affect system files, since applications store their data in isolation.
The Downloads folder is the first place to look if you are running low on space. Often gigabytes of forgotten files are stored there, which can be deleted without harm to the system.
Transferring data to a memory card and to the cloud
If the internal memory of the device is physically limited, the best solution is to use an external memory card microSD. Smartphones Samsung support large-capacity cards, which allows you to transfer your entire media library to them. To do this, insert the card into the slot, then go to the application My files, select the internal storage, mark the folders DCIM, Pictures, Video and Music, and use the function Move to transport them to the SD card.
It is important to distinguish between the “Move” and “Copy” functions. Moving files removes files from internal storage, freeing up space, while copying creates a duplicate, taking up space on both media. After transferring, make sure that in the camera settings you select saving new pictures to the memory card so that the problem does not return in the future. This is configured in the settings of the Camera application itself.
An alternative to a physical card is cloud storage, such as Google Photos, OneDrive or Yandex.Disk. These services offer features to automatically download and then free up space on your device. For example, Google Photos has a "Free up space" button that deletes photos and videos from your phone that are already securely stored in the cloud. This allows you to access your entire media library via the Internet without loading your local storage.
⚠️ Attention: Memory cards have a slower writing speed compared to the internal memory of a smartphone. It is not recommended to install applications on them or transfer system folders, as this can lead to slowdowns in the operation of apps.
The use of cloud technologies also protects your data from loss in the event of a breakdown or loss of the phone. Setting up automatic sync requires a stable Wi-Fi connection, but provides peace of mind that your memories are safe. By combining the use of an SD card for archived videos and the cloud for important photos, you can achieve the ideal balance between data availability and free space.
Is it possible to delete the Android folder on a Samsung phone?
Complete deletion of the folder Android is strictly not recommended, since it stores data from all installed applications, their cache and settings. Deleting this directory will reset all apps to the factory state, loss of progress in games and possible errors in the system. You can only clear individual subfolders inside Android/datathat belong to deleted applications.
Why is the space not freed up after deleting files?
A common reason is that the files are located in the Gallery recycle bin or the "Trash" folder in the "My Files" application. It is also possible that the deleted files have been cached by the system and a device reboot is required to update the storage statistics. In rare cases, clearing the cache of the Device Manager application itself helps.
How to transfer applications to a memory card on Samsung?
In modern versions of Android and the One UI shell, the ability to completely transfer applications to an SD card is limited by developers. If the application supports this function, the "Change" button for selecting a memory card will be active in the menu Settings → Applications → [Selected application] → Storage . If there is no button, the transfer is impossible without root access.
What is "Other" in the phone storage?
The "Other" category includes system files, operating system cache, data applications that do not fall into the main categories, as well as files of unknown formats. Often, remnants of deleted apps, update files, and temporary system operation data end up there. Clearing the cache and rebooting usually reduces the size of this partition.
Is it safe to use applications to clear memory?
Most third-party “cleaners” duplicate the functions of Samsung’s built-in optimizer, but at the same time consume more resources and display ads. Built-in One UI tools are the most secure and efficient. Third-party applications should be used with caution, granting them only the necessary permissions to avoid data leakage.
