Smartphone Samsung Galaxy A20s, despite its age, remains a reliable device for everyday tasks, but over time, users begin to notice a decrease in performance. The reason for this is often the accumulation of temporary files that take up valuable space in the internal memory. Understanding how to properly manage this data is key to maintaining stable operation of your gadget over time.

Cache memory is a special section of storage where the system and applications save intermediate data for quick access in the future. For example, when you open your favorite social network, pictures and interface elements are not downloaded from the server every time, but are taken from local storage. However, if these files become outdated or damaged, this can lead to interface freezes or incorrect display of content.

In this material, we will take a detailed look at all the available methods for clearing temporary files on your device. You will learn to distinguish between cache types, understand when you need to clear the data of a specific application, and when you need to completely clear the system partition. A competent approach to maintenance internal memory will allow your Galaxy A20s to work as quickly as on the day of purchase.

What is cache and why it needs to be cleared on Samsung A20s

Many users confuse cache with personal files, such as photos or contacts, but these are fundamentally different entities. A cache is a set of temporary data that is generated during the operation of the operating system Android and installed apps. This data is not critical to maintaining your personal information, so deleting it is safe.

The main problem arises when the volume of such temporary files becomes too large. On a model Samsung A20sthat has a limited amount of internal memory in basic configurations, a full cache can cause a critical lack of space. The system begins to work slower, as it is more difficult for the processor to find the necessary information among gigabytes of junk files.

Regular cleaning helps eliminate software errors, which often manifest themselves in the form of sudden application crashes. If a app starts to work incorrectly, resetting its cache often solves the problem without the need to reinstall. This is the first step in diagnosing any oddities in the behavior of your smartphone.

⚠️ Attention: Clearing the cache only deletes temporary files. Your logins, passwords and basic application settings will be preserved, unlike completely clearing the data.

Clear the cache once a month to maintain optimal speed, especially if you actively use heavy applications like social networks or games.

Clearing the cache of individual applications through the settings

The safest and most accurate method of freeing up space is This is working with the memory of specific apps. It often happens that one application, for example, a messenger or a browser, takes up a disproportionate amount of space compared to others. Owners Samsung Galaxy A20s can easily control this process through the standard settings menu.

First, you need to go to the main section of the device configuration. Find the item responsible for managing apps and select the application you are interested in. Inside the application menu, you will see information about memory consumption, where the total size, data size and cache size will be clearly divided.

Click on the clear cache button to delete temporary files of that particular app. This process only takes a few seconds and does not require rebooting the device. If you notice that an application is running slowly, start diagnosing with this procedure.

  • 📱 Go to Settings and select the section Applications.
  • 🔍 Find the one you need in the list app, for example YouTube or Instagram.
  • 🗑️ Click on the item Memory, and then the button Clear cache.
  • ✅ Check the free space in shared storage.

It is worth noting that for some system applications the cleanup button may be inactive or missing. This is normal behavior for critical components. Interfering with such processes unnecessarily can lead to instability. operating system. Interfering with such processes unnecessarily can lead to instability.

Using the built-in Samsung optimizer

Company Samsung implemented in shell One UI a powerful tool for automatic device maintenance. This service scans the system for unnecessary files, background processes and excess cache, offering the user (in one click) to optimize the operation of the smartphone. This is the easiest way for those who do not want to understand the technical details.

To use this function, go to the settings menu and find the device maintenance section. The system will automatically analyze the current memory, battery and security status. If an excessive amount of temporary files is detected, you will be prompted to delete them to speed things up.

The optimization function also closes background applications that consume RAM RAM. This is especially useful for Galaxy A20s, since the amount of RAM in this model is small, and background processes can significantly slow down the interface. Regular use of this tool will help maintain smooth animations.

Cleaning type What is deleted Security Recommended frequency
Application cache Temporary app files Completely safe Once a week
Optimizer Cache + background processes Safe Once a day
System cache OS temporary files Requires reboot In case of failures
Application data Settings and logins Dangerous (reset settings) Only in case of problems

It is important to understand the difference between simply clearing the cache and resetting application data. The optimizer usually only offers safe actions, but if you manually go into the app settings, be careful when choosing buttons. Accidentally clicking "Clear data" will delete all your correspondence history or settings within a specific service.

Full clearing of the system cache via Recovery Mode

Sometimes standard methods are not enough, especially if the smartphone began to behave strangely after updating the firmware. In such cases, access to the hidden recovery menu known as Recovery Modeis required. This mode allows you to clear the cache partition of the entire system without affecting the user's personal files.

To enter this mode, you must perform a certain key combination when the device is turned off. First, completely disconnect the smartphone by holding the power button until the shutdown menu appears and confirm the action. After the screen goes dark, you can proceed to the combination of buttons. Samsung Galaxy A20s you need to perform a certain key combination when the device is turned off. First, completely disconnect the smartphone by holding the power button until the shutdown menu appears and confirm the action. After the screen goes dark, you can start using the button combination.

Hold down at the same time: Volume up button + Power button

Hold these buttons until the logo appears Samsung, then release the power button, but continue to hold the volume. After a few seconds you will see a menu with text in English. Navigation here is carried out using the volume buttons, and the choice is confirmed by the power button.

⚠️ Attention: In the Recovery menu, do not select the "Wipe data/factory reset" item if you do not want to completely erase all data from the phone. You only need "Wipe cache partition".

Using the volume keys, find the line Wipe cache partition and confirm the selection. The cleaning process will take a few seconds, after which the system will prompt you to restart the device. Select item Reboot system now to return to normal operation. This method effectively solves problems with freezes after updates.

What to do if the Recovery menu does not appear?

On new versions of Android (11 and higher), to enter Recovery you may need to connect the phone with a USB cable to the computer. Try connecting the device to the PC before pressing buttons.

Web browsers and social networks deserve special attention, since they are the main consumers of disk space. When surfing the Internet Google Chrome or Samsung Internet save a huge number of images and scripts. Over time, this leads to the browser starting to work slowly or display old versions of sites.

In the settings of the browser itself, there is usually a convenient “History” or “Privacy” section, where you can choose to delete data for a certain period. It is recommended to clear your image and file cache, but you can leave saved passwords and browsing history if they are important to you. This is a fine-tune that allows you to free up space without sacrificing convenience.

Social apps like Telegram or Viberhave their own built-in memory management tools. They often cache the videos and photos you've watched, even if you didn't save them to your gallery. By going to the storage settings inside the application, you can delete the cache for the last days or weeks, which will instantly free up hundreds of megabytes.

  • 🌐 In the browser, go to Settings → Privacy.
  • 🗑️ Select the item Clear history and check only "Images and files".
  • 💬 In messengers, use the built-in section Data and memory.
  • 📉 Set a cache size limit, if the application allows it.

Regular monitoring of these applications is critical for owners of budget devices. On Samsung A20s memory capacity is not flexible, and several gigabytes of cache from video services can take up a significant part of the available space, preventing the installation of new important updates.

💡

Built-in cleaners inside messengers work more efficiently than system cleaning, since they know exactly which files can be deleted without harm to correspondence.

Frequent mistakes and additional recommendations

When trying to optimize the operation of a smartphone, users often make mistakes that can lead to the opposite effect. For example, installing dubious “cleaner” applications from the Play Market often only clogs the system with ads and additional background processes. The built-in tools Android are quite enough for competent maintenance.

Another common mistake is constantly clearing the cache of all applications in a row every day. This makes the caching mechanism itself meaningless: the phone is forced to re-download and process data every time you launch apps, which increases traffic consumption and loads the processor. Only do this if you are experiencing problems or running out of space.

It is also worth remembering that after clearing the cache, some applications may take a little longer to launch the first time. This is a normal situation as the system takes time to create new temporary files. Do not be alarmed if immediately after the procedure the phone seems a little thoughtful - this will pass after a couple of minutes of active work.

⚠️ Attention: The menu interface may vary slightly depending on the One UI firmware version. If you do not find the item you need, use the search in the settings.

For maximum efficiency, combine methods: use the built-in optimizer for daily prevention and manually clearing the cache of heavy applications once a week. This approach will ensure a balance between speed and ease of use of yours Galaxy A20s.

Disable automatic downloading of media files in messenger settings - this will prevent the memory from quickly filling up with unnecessary pictures and videos.

Questions and answers (FAQ)

Will my WhatsApp correspondence be deleted when cleared cache?

No, clearing the cache does not affect the message database. Your correspondence, photos and contacts will be preserved in full. Only temporary files necessary for displaying the interface are deleted.

Why does the cache quickly fill up again after clearing?

This is normal system behavior. Applications constantly create new temporary files for their work. The cache begins to take up a lot of space only if it has not been serviced for a long time or an error has occurred in the application.

Is it safe to use third-party apps for cleaning?

In most cases, they are not necessary. Built-in Samsung tools work more efficiently and securely. Third-party utilities often contain advertising and can themselves consume system resources.

Do you need to restart your phone after clearing the application cache?

Usually, a reboot is not required, the changes take effect instantly. A reboot is necessary only after clearing the system cache partition through the Recovery menu.

Can clearing the cache speed up charging of the phone?

Indirectly, yes. If background processes do not constantly access the full storage, the load on the processor will decrease, which may slightly reduce power consumption in standby mode.
