Complete guide to clearing the cache on Samsung Android

Modern smartphones Samsung based on the operating system Android over time accumulate a huge amount of temporary data. These files, known as caches, are designed to speed up applications, but when they accumulate in excess, they begin to slow down the system and take up precious space in the internal memory. Users often notice that their once-fast flagship begins to freeze, and notifications about low memory appear more often, even if enough photos and videos have been deleted.

Full clearing the cache on devices Galaxy S, Galaxy A or Galaxy M is not just removing garbage, but a comprehensive optimization procedure. There are several levels of cleaning: from deleting specific application data to deep cleaning of the system recovery partition. In this article, we will analyze each method in detail, explain the difference between cache types, and help you return your device to its former performance without losing personal data.

It is important to understand that regular memory maintenance is the key to a long service life for your mobile device. Ignoring this procedure may result in software failures and incorrect operation of important functions. Let's take a look at how to properly manage temporary files on your smartphone.

What is cache and why it needs to be cleared on Samsung

Cache is an area for storing temporary data that an application downloads from the Internet or creates during operation. For example, the browser Chrome or Samsung Internet saves copies of visited pages so that they open instantly the next time you visit. Social networks cache downloaded images and videos to avoid wasting traffic repeatedly. This is a useful mechanism that saves time and CPU resources.

However, over time, the size of these temporary files can grow to several gigabytes. Outdated cache may contain corrupted data that causes conflicts when running apps. In such cases, the application may crash immediately after opening or may not work correctly. This is especially true for heavy games and instant messengers that actively use network resources.

Another reason for cleaning is to free up space. On smartphones with a small amount of internal memory (for example, 64 GB), the cache can take up to 20-30% of the total space. The system begins to work slower because it does not have enough resources to write new temporary files and swap. Regular cleaning helps maintain stable operation of RAM and storage.

⚠️ Attention: Clearing the application cache does not delete your logins, passwords or correspondence. However, clearing data (not to be confused with the cache) will completely reset the app to its factory state, deleting all of your history and settings within it.

Clearing the cache of individual applications through settings

The easiest and safest way to free up space is to delete temporary files of a specific application that consumes a lot of resources. This method does not affect system files and is guaranteed not to cause problems with the phone. You can selectively clear the cache for the browser, YouTube or any other heavy application.

To perform this procedure, you need to go to the settings menu of your device. Navigation in the shell One UI may vary slightly depending on the version of Android, but the general algorithm remains the same for all models. Samsung. You will need to find the application management section and go to the memory usage details.

Follow the following steps sequentially:

• 📱 Open Settings and go to Applications.
• 🔍 In the list, find the desired application (for example, YouTube) and click on it.
• 💾 Select Storage or Memory.
• 🧹 Press the button Clear cache at the bottom of the screen.

Please note that the button Clear data is located nearby, but you should press it only in extreme cases, when the application is working with critical errors. After clearing the cache, the application will start a little slower than usual, since it will have to re-download the necessary resources from the network. This is normal behavior and will quickly return to normal.

Using the built-in tool "Device Maintenance"

The company Samsung has implemented a powerful built-in system optimization tool in its smartphones, called "Device Maintenance". This utility automatically analyzes the status of the battery, memory and security, prompting the user (with one click) to solve the main problems. This is the most recommended method for ordinary users who do not want to delve into technical details.

This tool not only deletes temporary files, but also closes background processes that consume RAM. It also checks the device for malware and optimizes power settings. Using a standard tool is preferable to installing third-party “cleaners”, which are often a source of advertising and unnecessary load on the system.

To use this function, follow these instructions:

1. Go to Settings.
2. Find and open the section Device Maintenance (or Device Care).
3. Click on the item Memoryto see detailed statistics.
4. Press the button Clean now to delete unnecessary files.

The system will automatically detect files that can be safely deleted, including ad cache, remnants of deleted applications and temporary download files. The process usually takes no more than 10-15. seconds. After completion, you will see a message about how many megabytes or gigabytes have been freed.

Deep cleaning: resetting the cache partition via Recovery Mode

There is a more advanced one a cleaning method that affects the system cache of the entire device, and not individual applications. This cache is stored in a special hidden section and contains temporary data from the operating system itself. Clearing this section often helps solve problems after a major firmware update, when the phone starts to heat up or quickly discharges. To access this mode, you need to reboot the smartphone into a special recovery menu. ( Android. Clearing this partition often helps solve problems after a major firmware update, when the phone starts to heat up or quickly discharges.

To access this mode, you need to reboot your smartphone into a special recovery menu (Recovery Mode). It is important to note that on new models Samsung with Android 11 and higher, to enter this menu you may need to connect the device to the computer via a USB cable. This is a security measure introduced by the manufacturer.

Step-by-step guide for entering recovery mode:

• 🔌 Connect your turned off smartphone to your PC via a USB cable.
• 🔘 Press the buttons Volume up and Power.
• 📱 Hold the buttons until the logo appears Samsung, then release.
• ⬇️ Using the volume buttons, select the item Wipe cache partition.
• ✅ Confirm the selection with the power button.

After completing the cleaning process, which usually takes a few seconds, you need to select the item. Reboot system now. The phone will reboot in normal mode. The first boot after this procedure may take longer than usual - this is normal, as the system recreates the necessary temporary files.

⚠️ Attention: The Recovery menu is navigated only with the volume buttons (up/down) and the power button (select in this mode). does not work. Be extremely careful and do not select the "Wipe data/factory reset" option, otherwise all your data will be deleted.

What to do if the Recovery menu does not appear?

On some new Samsung models, you must first connect the phone to the computer with a cable, and only then press the buttons. Without connecting to the PC, the key combination may simply reboot the phone in normal mode.

Comparison of cleaning methods and their impact on the system

Different cleaning methods have different degrees of impact on the operation of the smartphone. It is important for the user to understand which tool to use in a particular situation. Below is a table comparing the main approaches to deleting temporary files on devices Galaxy.

Cleaning method	Access level	Data security	Recommended frequency
Application settings	Custom	Absolutely safe	As needed
Device maintenance	System	Safe	Once a week
Recovery Mode (Wipe Cache)	Deep system	Safe (does not touch photos/contacts)	After software updates
Third-party cleaners	Miscellaneous	Risk of advertising and data collection	Not recommended

As can be seen from the table, built-in tools Samsung are the most balanced solution. Using third-party software often does more harm than good, since such applications constantly hang in the background and consume resources. Deep cleaning via Recovery is “heavy artillery” that should be used in case of obvious system failures.

Regular use of the “Device Maintenance” function allows you to avoid the need to go into the recovery menu. However, if you notice that the phone has become unstable after updating to a new version Android, resetting the cache partition will be the most effective solution to the problem.

Automation of the process and prevention of contamination

In order not to have to do manual cleaning every time the memory is full, you can set up automatic scripts. Modern versions of the shell One UI have the "Auto-optimization" function, which can be activated in the device maintenance menu. It will automatically close unnecessary applications and delete temporary files in the background.

It is also worth paying attention to the settings of specific applications. Many instant messengers, such as Telegram or Viberhave their own media cache settings. You can set a limit on the cache size or configure automatic clearing of downloaded photos and videos after a certain period of time. This will prevent data folders from growing.

In the Telegram settings, for example, the path looks like this: Settings → Data and memory → Memory usage → Auto-delete. By setting it to 3 days or 1 week, you ensure that old media files don't take up space forever. Such a preventive measure is often more effective than periodic manual cleaning of the entire phone.

⚠️ Attention: The settings interface and the names of menu items may vary slightly depending on the firmware version and model of your Samsung 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)

Will my WhatsApp correspondence be deleted when clearing the cache?
