Cleaning memory on Samsung: how to remove all junk

Modern smartphones Samsung Galaxy have powerful hardware, but slow down over time due to full storage. The accumulation of temporary files, application cache and forgotten downloads is a natural process of use Android. However, when the free space runs out, the system begins to work unstable, and photos and videos are no longer saved.

Device owners often wonder why the phone “flyed” after purchase, and a year later it slows down when opening the menu. The answer lies in data fragmentation and lack of regular maintenance. In this article, we will look in detail at how to safely free up gigabytes of space without deleting important personal data.

The optimization process does not require complex technical skills, but it is important to follow the sequence of actions. We will look at both built-in tools One UIand advanced methods for advanced users. The right approach to memory management will extend the life of your gadget for years.

Diagnostics and analysis of storage capacity

Before deleting anything, you need to understand what exactly is taking up space. The shell One UI from Samsung has an excellent built-in analyzer. Go to Settings → Device maintenance → Memory. Here you will see a color chart showing the distribution of data by category: applications, images, videos, audio and system files.

Pay attention to the “Other” section. Often this is where giant messenger cache files or remnants of deleted apps are hidden. The system may show that 90% of the space is occupied, but upon closer examination it turns out that half of the space is occupied by duplicate photos or old backups.

⚠️ Attention: Do not delete files from system folders through the file manager if you are not 100% sure of their purpose. This may lead to interface failure or data loss.

For deeper analysis, you can use third-party utilities, for example Files by Google or the built-in “My Files”. They allow you to sort objects by size. It often turns out that one forgotten movie in 4K resolution takes up more space than a thousand documents.

Using the built-in Samsung optimizer

The easiest and safest way to start cleaning is to use the standard maintenance tool. The company Samsung has integrated a powerful algorithm that automatically finds unused files and malware. Launch the Device Maintenance application directly from the desktop or through the settings.

Click the "Optimize Now" button. The system will check the RAM, battery status and storage. The algorithm will offer to delete temporary files and close background processes. This action is safe and does not affect your personal contacts or media files.

In the “Memory” section, click on the “Clear Now” button. You will see a list of categories that can be deleted: thumbnail files, browser cache, ad remains. The amount of freed space can vary from 100 MB to several gigabytes, depending on how long ago the last cleaning was done.

Data type	Impact on the system	Recommendation
Application cache	Speeds up launching apps	Clean regularly
Thumbnail files	Slows down the gallery when the volume is large	Delete safely
Advertising residues	Does not affect operation, takes up space	Required to delete
System logs	Needed for debugging errors	Delete only if there are problems

Manual clearing of cache and data applications

Automatic tools do not always cope with “heavy” applications, such as Telegram, Viber or TikTok. These apps save gigabytes of watched content in local memory. To clear them, you need to go to Settings → Applications and select a specific service.

In the application menu, find the “Storage” section. Here you will see two buttons: “Clear cache” and “Clear data”. The first deletes temporary files (pictures, videos from the feed), the second resets the application to its factory state, deleting logins and correspondence. Be extremely careful with the second option.

⚠️ Attention: Clearing messenger data will delete all correspondence history if it is not saved in the cloud. Make a backup of your chats before doing this.

For social networks and browsers, clearing the cache is a routine procedure. In Chrome or Samsung Internet you can configure automatic deletion of history when closing a tab. This prevents the accumulation of “digital fat” in the future.

Particular attention should be paid to applications for video calls and streaming. They often cache high-quality videos that you watch once and never open again. Regularly checking the list of installed apps will help identify such memory “eaters.”

Download and file system management

The folder Download (Downloads) is a black hole where everything falls: APK installation files, pdf documents, pictures from the Internet. Many users forget about this directory for months. Open the My Files app and sort the contents of your Downloads folder by date or size.

Delete all installation files APK. Once the app is installed, they become useless garbage. Also check the folder Bluetoothif you have ever received files using this protocol. There are often old presentations or music tracks lying there.

Use the duplicate search function. New versions One UI have a built-in tool for searching for identical photos and videos. It analyzes the metadata and suggests removing copies, leaving the original in better quality. This can free up a significant amount of space.

Hidden Android folders

There is an Android/data folder in the file system where applications store their caches. Clearing this folder manually may reset game settings and offline maps of navigators. Do this only if you understand the risks.

Don't forget about the shopping cart. In “My Files” and “Gallery”, deleted items do not disappear immediately, but are moved to the trash, where they are stored for 30 days. To instantly free up space, you need to go to the trash and click “Empty.”

Transferring data to a memory card and to the cloud

If the internal memory is physically small, the logical solution would be to use a microSD card. Modern flagships Samsung support cards up to 1 TB. Transfer all media files to it: photos, videos, music and documents.

In the camera settings, you can immediately specify saving new pictures to the memory card. To do this, go to the Camera application, click on the settings gear and select “Storage location” → Memory card. This will prevent the internal storage from filling up in the future.

⚠️ Warning: Memory cards are less reliable than internal storage. Do not store the only copies of important documents on them without duplication in the cloud.

Cloud storage is an alternative to a physical card. Services like Google Photos, Yandex.Disk or Samsung Cloud allow you to upload your media library to the Internet. After downloading, you can use the “Free up space” function, which will delete local copies, leaving only previews.

When transferring large amounts of data, use a computer. Connect your phone with a USB cable and copy files using File Transfer mode. This is faster and more reliable than wireless transfer or working with a file manager on the device itself.

Deleting unused applications and widgets

We often install applications “one time” and then forget about them. Not only do they take up space, but they also consume RAM in the background. Go through the list of all apps and remove everything that you have not used for the last 3 months.

Pay attention to the pre-installed software (Bloatware). Phones Samsung have many applications from Microsoft and Facebook that cannot be removed in the standard way. You can at least “Disable” them in application settings. This will hide them from the menu and prevent updates, saving space.

Widgets on the home screen also consume resources, although to a lesser extent. If you have a lot of live wallpapers or heavy news widgets installed, try replacing them with static ones. This will speed up the response of the interface and reduce the load on the processor.

To remove system applications that cannot be disabled through the menu, you need rights Root or use ADB commands from the computer. This is an advanced method that we will look at in the next section. For an ordinary user, a standard uninstallation is enough.

Advanced cleaning via ADB and developer mode

For those who want to get the most out of their device, there is a tool Android Debug Bridge (ADB). It allows you to remove system junk that is not visible to the user. To work, you will need a PC, a cable and USB debugging enabled in the menu Settings → About phone → Build number (press 7 times).

By connecting the phone to the computer, you can run a command to clear the cache of the entire system without losing data. This is especially useful if the phone starts to slow down a lot after a major firmware update.

adb shell pm trim-caches 999999999

This command forces the cache of all applications to be trimmed to a minimum. You can also remove specific system packages by knowing their name. For example, deleting unnecessary services Bixbyif you do not use them, can free up up to 500 MB.

Risks of using ADB

Incorrect removal of a system package can lead to a “bootlap” (infinite reboot). Always google the name of the package before uninstalling to make sure that it is not critical for the operation of the phone.

Another useful feature for advanced users is clearing Dalvik Cache. This is done through Recovery mode (turn off the phone, hold Volume Up + Power). In the recovery menu, select Wipe Cache Partition. This is safe for personal data, but resets temporary system files.

Frequently asked questions (FAQ)

Is it safe to use third-party apps like Clean Master?

Most of these applications are themselves a source of advertising and unnecessary garbage. The built-in optimizer Samsung is quite sufficient. Third-party cleaners often aggressively close background processes, which leads to increased battery consumption when they are started again.

Why does the memory quickly fill up again after cleaning?

Most likely, you have automatic media downloading active in instant messengers. Check your settings WhatsApp and Telegram and disable autosaving of photos and videos to the gallery. Also, the reason may be the cache of streaming services.

Is it possible to transfer applications to a memory card on Samsung?

In modern versions Android i One UI this function is often hidden or inaccessible for many applications for reasons of security and speed. The system forcibly keeps applications on the internal memory for performance.

What to do if the phone says “Memory full”, but the files are not found?

Try to restart the device in safe mode. If space is freed up, then a third-party application that creates hidden files is to blame. You may also need a full Factory Reset with a preliminary backup.

How to clear the DNS cache on Android?

This can be done through airplane mode: turn it on for 10 seconds and turn it off. Or through the developer settings by selecting the “Clear DNS cache” option. This helps if there are problems connecting to certain sites.
