The situation when your favorite smartphone suddenly starts to slow down, and a frightening notification appears on the screen that the internal storage is full, is familiar to many owners Samsung Galaxy. This is not just a minor inconvenience, but a serious problem that blocks the ability to take new pictures, install system updates, or even receive messages in instant messengers.
The operating system Androidinstalled on devices One UIover time accumulates gigabytes of temporary files, application caches, and forgotten downloads. Often, users don't realize where exactly those free gigabytes are disappearing until it's too late.
In this article, we'll look at detailed methods for freeing up space, from simple built-in tools to advanced settings that will help restore your device to its former speed.
Diagnostics: what exactly is taking up space
Before deleting everything in a row, you need to understand the structure of filling your storage. The system Samsung provides a convenient tool for data visualization, which shows the distribution of memory by category.
Go to the menu Settings → Device maintenance → Memory. Here you will see a pie chart or list that clearly shows how much space apps, images, videos, audio files, and documents are taking up. It often turns out that the lion's share of space is consumed not by the apps themselves, but by their cache or downloaded files.
Pay special attention to the "Applications" section. Some social networks or instant messengers can take up tens of gigabytes due to the saved history of correspondence and media files. Cached data can be deleted safely, while deleting the applications themselves will require re-installation.
⚠️ Attention: Before mass clearing, make sure that your important photos and documents saved in cloud storage or on a computer to avoid irreversible data loss.
Using the built-in Samsung optimizer
The easiest and safest way to start fighting for free space is to use the native utility from the manufacturer. In the shell One UI this tool is called "Optimization" and is available directly on the main screen or in the settings.
Click on the "Device Optimization" widget or go to Settings → Device maintenance. The system will automatically analyze the state of the smartphone, check for malware, assess the battery charge and, most importantly, scan the memory for unnecessary files.
After clicking the "Optimize now" button, the smartphone will delete temporary files that are not in use right now and close background processes. This action will not delete your personal photos or contacts, but it can free up from 500 MB to several gigabytes of space.
This menu also includes a "Clean Now" option for random access memory (RAM), which will help speed up the device if it freezes due to lack of resources, although this does not directly affect the internal storage.
Run the built-in optimization at least once every week to prevent the accumulation of large amounts of temporary garbage.
Manually clearing cache and application data
If automatic optimization does not give the desired result, you will have to resort to manual cleaning. This is the most effective method, as it allows you to precisely delete data from the most “heavy” apps.
Go to Settings → Applications. Sort the list by size (usually this can be done through the sort menu in the top right corner). You will immediately see the leaders in space consumption. Most often this is YouTube, Instagram, TikTok or instant messengers.
Select an application and go to the Memorysection. Here you will see two buttons: “Clear cache” and “Clear data.”
- 🗑️ Clear cache: deletes temporary files (pictures, scripts) that the application downloaded for fast operation. This is safe and does not affect your logins or correspondence.
- 💣 Clear data: resets the application to its factory state. You will be forced to re-enter your passwords and set up your profile. Use this only if the cache takes up an abnormally large amount of space.
Particular attention should be paid to messengers like Telegram or Viber. They have their own built-in data storage settings, which are often more efficient than system ones. For example, in Telegram you can configure automatic clearing of the media file cache.
⚠️ Attention: Clearing application data will delete all local information, including draft messages and settings within the app. Do this consciously!
☑️ Cleaning a heavy application
Deleting duplicates and large files
Over time, hundreds of identical pictures taken in burst mode, or unsuccessful takes, accumulate in the gallery. Also, users often forget about downloaded films or archives, which lie like dead weight.
In modern versions One UI (starting from version 4.0 and higher), a duplicate search function has appeared in the "Gallery" application or in the "Device Maintenance" menu. The system itself will prompt you to select similar images and delete unnecessary ones, leaving only the highest quality.
To search for large files, use the built-in file manager My Files (My files). Go to the "Storage Analysis" section. Here the files are sorted by type and size.
Pay attention to the folder Download (Downloads). Often, APK installation files of old versions of apps that are no longer needed, or PDF documents that you opened once six months ago are stored there.
How to find hidden large files?
Sometimes large files are hidden in messenger folders. Go to My Files → Internal memory → Android → media. There may be cached videos from social networks that are not visible in the gallery.
Transferring data to an SD memory card
If your smartphone Samsung supports the installation of microSD memory cards, this is an ideal way to solve the problem of lack of space once and for all. Internal memory is intended for the system and applications, and it is better to store media files on external media.
After installing the memory card, the system will offer to use it as portable storage. You can transfer photos, videos, music and documents there.
To transfer existing files, open the application My files, select the desired folders (for example, DCIM for photos), click "Move" and select the memory card as the destination.
In addition, in the camera settings, you can set new pictures to be saved directly to the SD card. To do this, open the camera, go to the settings (gear) and select Save location → Memory card.
| Data type | Recommended storage location | Why |
|---|---|---|
| System applications | Internal memory | Ensures maximum system speed |
| Photo and Video | SD memory card | Take up a lot of space, easy to carry |
| Music and Podcasts | SD memory card | Do not require high reading speed |
| Messenger cache | Internal memory (with cleaning) | Frequent access requires a fast drive |
⚠️ Attention: Memory cards are slower than internal flash memory. Do not transfer active games or heavy work applications to them, otherwise they may slow down.
Regularly transferring media files to a memory card is the best way to maintain the speed of the smartphone's internal memory.
Cloud storage as an alternative
If buying a memory card is not part of your plans, using cloud storage would be an excellent solution services. Samsung Cloud, Google Photos and OneDrive allow you to store terabytes of data on the Internet, freeing up space on the device.
Service Google Photos has a convenient “Free up space” function. After all your pictures are uploaded to the cloud, the application finds copies of these photos on your phone and deletes them, leaving access to viewing via the Internet.
It is also worth checking the synchronization settings. You may have enabled saving original photos in full resolution, which quickly eats up memory. Switching to the "Space Saving" (compression) mode will allow you to store thousands of pictures for free.
Do not forget that to work with the cloud you need a stable Internet. However, this is a small price to pay for the opportunity not to delete memories dear to your heart due to a lack of gigabytes.
Set up automatic uploading of photos to the cloud only when connected to Wi-Fi, so as not to waste mobile traffic.
Why does the memory fill up immediately after cleaning?
This may happen due to background processes that are actively writing logs, or due to the fact that messengers continue to automatically download media from chats. Check your startup settings in WhatsApp and Telegram.
Is it possible to delete the Android folder?
No, you absolutely cannot delete the entire folder. Android It is absolutely impossible. This will break the applications. You can clean only the subfolder cache inside it, and then with caution.
Does full memory affect Internet speed?
Indirectly, yes. If the memory is full, the system has no place to create temporary files to buffer web pages, which can lead to browser freezes and slow loading of content.
How to clear the cache of all applications at once?
In new versions of Android, this function is hidden. The easiest way is to go to the developer menu (if enabled) or use third-party utilities, but the safest way is to clean the heaviest applications manually one at a time.
What is "Other" in the storage?
The "Other" section usually contains system files, application data that the system cannot classify, and temporary update files. Clearing the cache and rebooting often reduces this partition.
