Modern smartphone has become a universal tool for work and entertainment, but the abundance of running apps often leads to a slowdown of the system. Users often notice that the device starts to slow down and the battery drains faster than usual, even if you are not playing heavy games. The reason for this behavior is often the so-called “extra windows” - background processes, frozen applications or even malicious advertising that consume processor resources.
In the operating system Android memory management is more complicated than on a PC, however, the accumulation of temporary files and cache can significantly affect the performance of the interface. If you notice that the screen is filling up with strange banners or the list of running tasks is full, you need to take action immediately. Proper cleaning will allow your device to return to its former speed and responsiveness without the need to take it to a service center.
In this guide, we will analyze in detail all the methods of dealing with digital garbage and intrusive interface elements. You will learn to distinguish system processes from malicious ones, and also understand how to properly close applications so as not to harm the stability of operation operating system. Follow the instructions sequentially to achieve maximum effect.
Diagnostics of the problem: what is taking up memory
Before taking active steps to remove unnecessary windows, you need to understand the nature of their appearance. Users often confuse regular notifications from status panels with actually running applications that hang in RAM. In fact, Android is designed to keep frequently used apps in RAM to launch them instantly, and forcing all processes to close can even increase battery drain the next time you start.
However, there are situations where intervention is really necessary. For example, if the application has stopped responding to commands, the interface is frozen, or you observe strange system behavior. In such cases, it is important to check the task manager. On most modern shells, this is done by swiping from the bottom up and holding your finger down, or by pressing a special navigation button.
Pay attention to which apps consume the most resources. Often these can be heavy games, navigators or video editors that were not closed correctly. It is also worth checking for recently installed applications that may be running in the background without your knowledge.
- 📱 Check the list of running applications through the multitasking menu.
- 🔋 Analyze the "Battery" section in the settings to look for energy hogs.
- 🚫 Pay attention to applications with administrator rights, which may block windows from closing.
⚠️ Attention: Do not try to forcefully terminate system processes whose names are unfamiliar to you. This can lead to unstable operation of the interface or even a cyclic reboot of the device.
Standard methods for closing applications
The easiest and safest way to remove unnecessary windows is to use built-in navigation tools. Depending on the version Android and model of your smartphone (be it Samsung, Xiaomi or Pixel), the controls may differ slightly, but the logic remains the same. Usually it is enough to press the "Menu" button (square or three bars) or swipe up from the bottom edge of the screen.
The menu that opens will show cards of all active applications. To close a specific window, you just need to swipe the card up or to the side. If you want to close everything at once, find the “Close All” or “Clear” button, which is usually located at the bottom of the screen or in the corner of the list. This operation frees up RAM, but does not delete application data.
In some cases, a standard shutdown may not work if a process is hung at the system kernel level. Then a deeper approach through settings will be required. Go to Settings → Applications → Manage applications. Here you will see a complete list of installed software. Select the problematic application and click the "Stop" or "Close" button.
☑️ Check running processes
It is important to understand the difference between closing an application and deleting it. Closing only unloads the app from RAM, but leaves its files on the drive. Uninstalling it erases the app completely. If an extra window appears due to an error in the app code, reinstalling it can solve the problem.
Fighting advertising windows and viruses
The situation changes dramatically if “extra windows” appear on their own, covering the desktop or popping up as banners on top of other applications. This is a sure sign of the presence adware virus or unwanted software (Adware). Such apps are often disguised as useful utilities: flashlights, QR code scanners or memory cleaners.
The first step in the fight against intrusive advertising is to identify the culprit. When an advertising window pops up on your screen, do not close it immediately. Press the menu button (square) or go to the multitasking menu. There you will see which application created this window. Remember its name and icon, then delete it immediately.
If you cannot visually determine the source, use the settings. Go to Settings → Applications and carefully review the list. Look for apps without a name, with a blank icon, or ones that you did not knowingly install. Often malware hides at the very bottom or beginning of the list in order to go unnoticed.
⚠️ Attention: If the application is not removed through the standard menu, it may have received device administrator rights. You need to go to the security settings and revoke these rights before deleting.
To prevent and clean an already infected device, it is recommended to use specialized anti-virus scanners. They are able to find hidden miners and Trojans that do not appear in the regular application list. After scanning, be sure to restart your smartphone in safe mode to make sure that malicious code is not active.
What is safe mode?
Safe mode is a special mode of Android operation in which only system applications are launched. This allows you to remove a virus if it is blocking the normal operation of your phone. To enter, you usually need to hold down the power button, and then click on the “Turn off” item on the screen.
Clearing cache and browser data
Often, the source of unnecessary windows is not individual applications, but web browsers. While surfing the Internet, sites save cookies, scripts and cached images on the device. Over time, this volume can reach hundreds of megabytes, which leads to slow loading pages and the appearance of pop-ups with offers to buy or download something.
To remove this digital garbage, you need to clear your browser data. Go to Settings → Applications and find your browser (Chrome, Samsung Internet, Yandex, etc.). Inside the application menu, select "Storage" or "Storage". There you will see two buttons: “Clear cache” and “Erase data.”
Clearing the cache is safe and does not affect your logins and passwords, it only deletes temporary files. However, erasing data will reset the browser to its factory state: history, saved passwords and settings will be deleted. Therefore, before this procedure, make sure that your data is synchronized with your account Google.
| Data type | What it deletes | Impact on accounts | Recommended frequency |
|---|---|---|---|
| Cache | Temporary files, website images | No effect | Once a month |
| Application data | Settings, logins, history, cookies | Exit all accounts | In case of problems |
| Cookies | Information about visited sites | May require re-login | For privacy |
It is also worth checking the site permissions. In your browser settings, find the "Sites" or "Privacy" sections. Make sure that no suspicious resource has permission to send notifications. It is through push notifications that spam windows are often received, which users mistake for viruses.
Using Developer Mode for Advanced
For advanced users who want to gain full control over windows and animations, there is a Developer Mode. This is a hidden menu that allows you to control the behavior of the system at a deep level. You can activate it by going to Settings → About phone and quickly pressing 7 times on the "Build number" item.
In the "For Developers" menu that opens, you can find parameters that affect the display of windows. For example, the Don't keep activities option causes the system to destroy each application as soon as the user leaves its screen. This is a radical method that is guaranteed to remove all unnecessary windows from memory, but makes multitasking impossible.
You can also limit background processes here. You can set a limit, for example, "No more than 2 processes". This means that the system will keep in memory only the two most recently launched applications, and the rest will be unloaded automatically. This is a great way to free up RAM on older devices with low memory.
Use the "Animate windows" option in developer mode, setting the value to 0.5x. This will not remove windows, but will visually speed up the interface, making transitions between windows sharper and faster.
Be careful when changing the settings in this section. Inexperienced intervention may result in some applications not working correctly or constantly closing at the most inopportune moments. Use these tools consciously, understanding the consequences for the operation of operating system.
Dramatic measures: reset and recovery
If none of the above methods helped remove unnecessary windows, and the system continues to work unstable, system files may be damaged. In this case, the last but most effective method remains - a full reset to factory settings (Hard Reset). This procedure will return the smartphone to the state it was in when purchased.
Before starting the procedure, it is critical to create a backup copy of all data. Resetting will delete absolutely everything: contacts, photos, correspondence and installed applications. Use services Google Photos and contact synchronization so as not to lose important information. After the reset, you can restore your data from the cloud.
To perform a reset, go to Settings → System → Reset settings. Select the "Erase all data (factory reset)" option. The device will reboot and begin the cleaning process, which may take 5 to 15 minutes. After turning on, you will receive a clean system without unnecessary junk and viruses.
⚠️ Attention: Make sure that the battery charge is at least 50% before starting the reset. Interrupting the process due to low battery may damage the phone software.
A full reset is a guaranteed way to remove any viruses and software errors, but it requires a mandatory backup of user data.
Why do windows open on their own after unlocking?
Most often this happens due to permissions given to specific sites in the browser, or the presence of a hidden malicious application. Check the list of installed apps for unknown names and turn off notifications for all sites in Chrome settings.
Is it possible to completely prevent applications from running in the background?
Yes, this can be done through the battery settings (power saving mode) or in the developer menu. However, this may result in you not receiving messages from instant messengers on time.
Are window cleaning apps safe?
Most of them are not needed, since Android knows how to manage memory itself. Some "cleaners" themselves are a source of advertising. It’s better to use built-in cleaning tools or proven antiviruses.
How to remove ads in specific applications?
This is usually done by purchasing a premium version of the application. If advertising pops up on top of the entire screen in a free application, it is most likely a virus, and it is better to remove the application.
