Modern mobile browsers store a huge amount of data to speed up page loading and authorization on sites, but over time these accumulations can turn into a source of problems. Cookies - these are small text fragments that sites record on your device to remember your preferences, products in cart or account login status. However, an excess of such data often leads to a slowdown of the smartphone, errors when loading pages and, more importantly, a decrease in the level of digital privacy.
Device owners Samsung Galaxy are faced with the need to clean out accumulated garbage more often than others, since the proprietary One UI shell has its own Features in managing system memory and application cache. Regular cleaning helps not only to free up space, but also to eliminate strange bugs when the site displays incorrectly or endlessly asks for a password. In this article, we will analyze in detail all the methods for deleting temporary files, from standard browser settings to using system optimization tools.
Why do you need to delete cookies on your smartphone?
Many users ignore browser maintenance until they encounter critical errors, but preventive cleaning brings tangible benefits to system performance. The main reason is that outdated or corrupted cookies could conflict with newer versions of web pages, causing content to fail to display or endless redirect loops. In addition, advertising trackers use this data to build a detailed profile of your interests, which reduces your privacy online.
Cleaning data also solves the problem of sites that “remembered” you in the wrong status or with outdated currency and language settings. If you notice that some popular resource is taking longer to load than usual or displays a 403 error, the first thing you should try is resetting the cache and cookies. This action is safe for most sites, although it will require re-entering passwords the next time you visit.
⚠️ Attention: Before mass cleaning, make sure that you remember passwords for important services (mail, banks, social networks), since the procedure for logging out of accounts will be automatic and instant.
It is also worth noting that on On devices Samsung with a small amount of built-in memory, the accumulation of browser caches can take up gigabytes of space over several months of active use. Regular maintenance allows you to maintain the interface performance at a high level, especially on models from previous years of production. Understanding how these files work will help you better control your digital hygiene.
Deleting cookies through the Google Chrome browser on Samsung
The most common way to manage data on Android is to use the built-in tools of the browser itself. In Google Chrome, which is installed by default on most smartphones, the cleaning process is intuitive, but has several hidden settings that are worth being aware of. First, you need to open the application and go to the main menu by clicking on the three vertical dots in the upper right corner of the screen.
In the drop-down list, select the item History, and then click on the link Clear history at the top of the screen. A new window will open asking you to select a time range. Here it is important to pay attention to the option Cookies and site data: make sure that the checkbox next to this item is checked, otherwise the cleaning will not affect the data we need. You can also select the "All time" period to delete absolutely all traces of your online activity.
Use the "Advanced settings" function in the clear menu to also delete autofill data and saved passwords if you transfer the phone to another person.
After selecting all the necessary parameters, press the button Delete data at the bottom of the screen. The system may ask you to confirm the action, since this is an irreversible operation. Once the process is complete, the browser will reload your current tabs and you will notice that many sites will require you to log in again. This is normal behavior and confirms successful deletion of session data.
- 🗑️ A complete wipe deletes all session saves, including active logins to mail and instant messengers.
- ⚡ Deleting old files often solves the problem with pages freezing when loading heavy resources.
- 🔒 Regularly resetting cookies limits the ability of advertising networks to track your movements across sites.
How to clear the cache in the proprietary Samsung Internet browser
Owners of flagship and mid-budget models Galaxy S and Galaxy A often use a pre-installed browser Samsung Internetthat is optimized specifically for AMOLED screens and the One UI interface. The cleaning mechanism here is slightly different from standard Android, providing more flexible privacy settings. To get started, open your browser and click on the menu icon in the form of three horizontal lines located in the lower right corner.
In the list that opens, go to the section Settings, scroll down to the item Personal data and select Delete personal data. You will see a list of categories of information stored on the device. Make sure that the switch opposite the item Site data and cache is active. A feature of this browser is the ability to selectively delete data only for specific sites through the “Select Sites” button, which is very convenient if you need to reset the settings of only one resource.
☑️ Check before clearing
After selecting the required parameters, click the red button Delete data at the bottom of the screen. The system will issue a warning that you will be logged out from most sites. Confirm the action and cleaning will take just a few seconds. Samsung browser allows you to set it to automatically delete data when you close the application, which is a great feature for those paranoid about security.
⚠️ Note: The menu interface may vary slightly depending on the version of the One UI shell and the firmware year of your Samsung smartphone.
If you use the "Secret Mode" mode in this browser, remember that the data from it is not displayed in the general history, but also takes up space. To delete them, you need to open the secret mode tab, press the menu and select Close all secret mode tabs, which will automatically erase all local data for this session.
Global data clearing through Android system settings
Sometimes you need to delete data for more than one specific browser, but for all web applications at once, or when the browser interface does not load due to errors. In this case, Android system settings come to the rescue, allowing you to manage the memory of each application separately. This method is the most radical and effective, since it deletes not only cookies, but also the entire accumulated cache and application databases.
Go to the main Settings of your smartphone Samsung and select the section Applications. In the list, find the browser you need (for example, Chrome or Samsung Internet) and click on it. Next, go to subsection Storage. Here you will see two buttons: Clear cache and Clear data. We are interested in the second option - Clear data, since it resets the application to the “as after installation” state, deleting all cookies, settings and temporary files.
| Action | What is deleted | Impact on accounts | Working speed |
|---|---|---|---|
| Clear cache | Temporary files, pictures | No (remain logged in) | Instantly |
| Clear data | Cookies, settings, databases | Full exit (password required) | 1-3 seconds |
| Delete application | Everything, including updates | Full reset | Depends on size |
| Reset phone settings | Absolutely everything on the device | Deleting a Google account | 5-10 minutes |
Using the system menu ensures that even those files that the browser for some reason cannot be deleted through its interface will be deleted. This often helps in cases where an application begins to consume an abnormally large amount of RAM or crashes constantly. After completing the procedure, the first time you launch the browser, it will behave like new, asking for search engine settings and synchronization.
What to do if the "Clear data" button is grayed out?
If the button is gray and cannot be pressed, check whether the application is assigned device administrator rights or whether the "Parental Controls" feature is activated, which may block changes to settings applications.
Automation of the process using the Device Care application
Samsung smartphones have a powerful built-in optimization tool called Device Care (or “Device Maintenance” in Russian localization), which allows you to clean garbage in a semi-automatic mode. While this feature primarily targets app cache and junk files, it also affects browser data if you configure the appropriate auto-cleanup settings. This is an ideal option for users who do not want to manually navigate through the menu every time.
Open Settings and find the section Device Maintenance. Click on the item Memoryto see detailed statistics on storage usage. A function Auto Cleanupis available here, which can be enabled in the additional settings menu (three dots in the corner). By activating it, you allow the system to automatically delete unused application files and clear the cache when the device is idle and charging.
For deeper cleaning in the same menu, you can use the button Clear Now. The system will analyze the device and offer to delete unnecessary files, including residual browser cache. While this method doesn't always remove cookies as thoroughly as a manual data reset, it's great for regularly maintaining system hygiene without the risk of accidentally losing important passwords.
- 🤖 Auto-clean works in the background and does not require user intervention.
- 📊 In the "Memory" section, you can see which browser takes up the most space.
- ⚙️ Settings can be flexibly configured, excluding important applications from the cleaning process.
⚠️ Attention: Automatic optimization functions may work differently depending on the version of One UI; always check which categories of files are selected for deletion in the autocleanup settings.
Managing third-party browsers: Firefox, Opera, Brave
If you prefer alternative solutions instead of standard browsers, such as Mozilla Firefox, Opera or Brave, the cleaning principle remains similar, but the menu layout may differ. In Firefox for Android you need to go to the menu (three dots), select Settings, scroll down to the section Deleting browsing data and check the box Cookies. A feature of Firefox is the ability to configure automatic deletion of cookies when closing the application.
In the browser Opera the scheme is as follows: click on Opera logo in the lower right corner, then to the settings gear. Scroll to the very bottom and find the item Privacy. There will be a button Clear browsing datawhere you can choose to delete cookies and cache. A privacy-focused browser allows you to do this even faster through a shield in the address bar or in the settings section Brave, privacy-focused, allows you to do this even faster through the shield in the address bar or in the settings section Shields and privacy.
Third-party browsers often have more advanced privacy settings that allow block trackers before they even save cookies on your device.
Everyone web engine keeps their data in isolation. Therefore, if you want to completely clear your traces of being on the Internet, you will have to repeat the procedure for each browser installed on your smartphone separately.
Frequently asked questions (FAQ)
Will clearing cookies delete my saved passwords?
In most cases, yes, if you select the "Clear data" or "Cookies and site data" option. Browsers store session tokens in cookies, so after cleaning the site will “forget” that you are logged in and will require you to enter your login and password again. However, the saved passwords themselves in a password manager (Google Password Manager or Samsung Pass) are usually not deleted unless you check the "Passwords" box.
Is it possible to delete cookies for only one specific site?
Yes, this is possible. In the settings of the Chrome and Samsung Internet browsers there is a section “Site Settings” or “Site Data”, which provides a list of all resources that have saved information on your phone. You can find the desired domain in the list, click on it and select the “Clear” or “Delete data” option without affecting other sites.
Is it safe to delete cookies for banking applications?
Yes, it is safe and even useful. Banking applications use their own secure communication channels and do not rely on web browser cookies for authorization within their application. Clearing your browser may require you to log in again only if you use the mobile version of the bank through the website and not through a separate application.
Why, after cleaning, does the site quickly create new cookies again?
This is normal behavior. Cookies are created by the website server when you first access it to ensure correct operation (for example, to remember the language or the shopping cart). Clearing deletes old, possibly incorrect data, but the next time you visit the site, it will create new, fresh files necessary for its functioning.
Will deleting a large number of cookies slow down your phone?
On the contrary, it will speed things up. The removal process takes a fraction of a second and does not load the processor. Freeing up storage space and eliminated data, on the contrary, has a positive effect on the speed of opening pages and the overall responsiveness of the browser.
