Modern brand smartphones Samsung, despite powerful characteristics, begin to work slower over time due to full internal memory. Users often notice that the camera freezes, applications crash, and the system notifies when the amount of free space is critically low. This is an inevitable process of accumulation of temporary files, cache and forgotten downloads, which requires regular intervention.
Correct storage optimization allows you not only to free up gigabytes of space, but also to extend the life of the device, reducing the load on the memory controller. In this article, we will look at standard shell tools One UIhidden system functions and manual methods for deleting data that are guaranteed to return your gadget to its former speed.
Many device owners mistakenly believe that to clean they must download third-party cleaner apps. In fact, built-in algorithms Android and specialized utilities from Samsung cope with this task much safer and more efficiently, without disrupting system processes.
Using the built-in device optimizer
The easiest and safest way to start fighting for free space is use the pre-installed “Device Care” tool. This system automatically analyzes the state of the phone and offers (in one click) to solve the main performance problems.
To start the process, you need to go to Settings → Device Maintenance. Here you will see a pie chart showing your current resource usage. Clicking on the "Optimize Now" button will launch a scan that will end with closing background applications and deleting obvious temporary files.
⚠️ Attention: Do not use the "Optimize" function too often (for example, every hour). This can lead to constant restarting of background services, which, paradoxically, will increase battery consumption.
Particular attention should be paid to the “Memory” section inside this menu. The system will show details by file type: images, videos, audio, documents and applications. Click on the "Files" item to see specific categories of data that take up the most space, for example, "Downloads" or "App Cache".
Regularly go to the "Storage" section once a week to delete files from the recycle bin, which are automatically erased only after 30 days.
Deep cleaning of application cache and system data
Cache is temporary information that applications save to speed up their work. Over time, this data can grow to several gigabytes, especially for social networks and instant messengers like Telegram or VK. Clearing the cache does not delete your logins, passwords or correspondence, so this procedure is completely safe.
To perform a deep clean manually, go to Settings → Applications. Select an application that takes up a lot of space (usually browsers or social networks) and click on the “Storage” item. Here you will see two buttons: “Clear cache” and “Clear data”.
- 🧹 Clear cache: deletes temporary files, speeding up the application without losing settings.
- 🗑️ Clear data: resets the application to its factory state, deleting all accounts and local settings.
- 📂 Storage management: allows you to see which files are taking up space inside the application.
You should not click “Clear data” for system applications such as Contact, Messages or Phoneif you are not sure about the availability of a backup copy. For third-party apps, this action will require re-authorization.
Analysis and removal of duplicates and large files
With the release of new versions One UI in the standard file manager My Files ("My files"), a function has been added to search for duplicates and large files. This eliminates the need to install third-party scanners, which often contain ads.
Open the My Files app and scroll down to the Storage Analysis section. The system will offer categories: “Similar images”, “Large files”, “Rarely used applications”. By clicking on a category, you can select files to delete in groups.
Files from instant messengers occupy a special category. Photos and videos sent in chats are often duplicated in the gallery. In the settings of the messenger itself (for example WhatsApp), you can disable autosaving of media to the gallery, which will prevent future blockages.
| File type | Medium size | Recommended action |
|---|---|---|
| Photo (JPEG/HEIC) | 3-8 MB | Remove duplicates, blurry pictures |
| Video (MP4) | 50-500 MB | Transfer to the cloud or PC |
| APK files | 50-200 MB | Delete after installing applications |
| Audio (MP3) | 5-10 MB | Check for relevance |
Deleting APK installation files after installing apps is the fastest way to free up space without losing the functionality of your phone.
Cleaning the downloads folder and temporary files
Folder Download ("Downloads") is the most common repository of digital waste. Browsers, email clients and instant messengers save everything you've ever downloaded here: from presentations and restaurant menus to old versions of software.
Go to “My Files” → “Downloads”. Sort files by date or size. There is a 99% chance that you no longer need files downloaded more than six months ago. Select them with a long press and delete.
⚠️ Attention: Before cleaning the “Downloads” folder, check for important documents (PDF, Word) that could have been saved there automatically after opening attachments from mail.
It is also worth checking hidden folders in the root of the internal memory. Some applications create their own cache directories, which are not always visible in the standard analyzer. To access them, you may need to enable the display of hidden files in the file manager settings.
Where can I find hidden folders with garbage?
At the root of the internal memory, folders with the names of deleted applications (for example, folders from games that you have already deleted) often accumulate. They can be safely deleted manually through the file manager.
Transferring data to an SD card and using the cloud
If your internal memory Samsung Galaxy is limited (for example, 64 GB or 128 GB), the best solution is to expand the storage using a microSD card. Modern flagships support cards up to 1 TB, which actually turns the phone into a portable media center.
After installing the card, go to Settings → Device maintenance → Storage. The system will offer to transfer some data. You can also manually change the save path for the camera: open the Camera application, click on the settings gear and select “Storage location” → SD card.
- ☁️ Google Photos: turn on synchronization and the "Free up space" function, which will delete copies of photos from your phone that have already been uploaded to the cloud.
- 💾 Samsung Cloud / OneDrive: use the Samsung ecosystem to backup contacts and notes, deleting their local copies.
- 📼 Streaming: refuse storing music and movies on your device in favor of streaming services.
It is important to understand that transferring the applications themselves to an SD card in modern versions Android is often unavailable or unstable. It is better to use a memory card exclusively for media files and documents.
Resetting settings as a last resort optimization measure
If none of the above methods helped free up enough space or the phone continues to be unstable, the problem may lie in deep system errors or file system fragmentation. In this case, a full reset to factory settings helps.
This procedure completely erases all data from the device, returning it to the “as from the store” state. Before you begin, be sure to create a full backup of your data via Smart Switch to your computer or to the cloud.
Settings → General settings → Reset → Reset data
After confirming the action, the phone will reboot and begin the cleaning process, which may take from 5 to 15 minutes. Do not interrupt the power supply to the device at this moment.
⚠️ Attention: The menu interface and item names may vary slightly depending on the version One UI and the model of your smartphone. If you do not find the specified item, use the search in settings (magnifying glass icon at the top of the screen).

Frequently asked questions (FAQ)
Is it safe use cleaner applications from the Play Market?
Most of these applications do not bring real benefits, since they duplicate the functions of the system. Moreover, they themselves consume battery resources and display intrusive advertising. The built-in optimizer Samsung is quite sufficient.
Why does the memory fill up immediately after cleaning?
The system Android and applications actively create new cache files for their work. This is normal behavior. Also check if automatic downloading of media files is enabled in instant messengers.
Is it possible to delete the Android folder on your phone?
No, you cannot delete the entire folder Android as it stores data from all installed applications. Removal will lead to app malfunctions. You can clear only the subsection cache inside it, but it is better to do this through application settings.
How to clear the cache of the entire system at once?
To do this, you need to enter Recovery mode (turn off the phone, hold down Volume Up + Power button). Select item Wipe Cache Partitionfrom the menu. This will delete the system update cache without affecting personal data.
