Smartphone owners Samsung Galaxy often face the need to force close a frozen app or free up RAM to improve device performance. In the Android operating system, especially in the shell One UI, standard management of running processes is hidden from the eyes of the average user more deeply than in pure versions of the OS. Many people are looking for a separate “Task Manager” application, believing that it should be placed on the desktop as a separate icon, but the real system architecture is structured differently.
In fact, application manager is integrated directly into the menu of open windows, and advanced memory management functions are located in the device’s system maintenance settings. Understanding how to properly interact with these tools allows you not only to close unnecessary processes, but also to extend the battery life of your gadget. In this material, we will analyze in detail all the ways to access task management, including hidden engineering menus and special codes.
Standard access through the menu of running applications
The fastest and most obvious way to get into the interface for managing active apps is to use system navigation. On modern smartphones Samsung with a shell One UI just press the “Menu” button (usually three vertical bars at the bottom of the screen) or swipe from bottom to top and hold your finger if gesture control is enabled. The window that opens shows not just a list, but a full-fledged manager of running processes.
Here you can see a preview of all open windows. Clicking on the button with three dots at the bottom of the screen opens an additional menu, where the “Close All” option is often located. However, it is important to understand that standard closing does not always completely unload the process from RAM, but only stops its visible part. For deeper cleaning, other actions are required.
- 📱 Press the "Menu" button or swipe to open the task list.
- 🗑️ Use the "Close All" button to shut down processes en masse.
- ⚙️ Click on the application icon at the top of the preview to access details.
It is worth noting that a long press on the application icon in this menu allows you to quickly go to its properties or forcefully stop working. This is especially useful if the app has stopped responding to touches. Unlike older versions of Android, there is no “Clear memory” button directly, but the functionality is hidden in the logic of the system.
System resource monitor and device maintenance
For those who are looking for a classic task manager with graphs of CPU and memory load, smartphones Samsung have a built-in monitoring tool. It is located on the way Settings → Device Maintenance → Memory. This displays the average amount of RAM used over the last 3, 6, 12 or 24 hours, which gives a more objective picture than a snapshot of the status.
In this section, there is a “Clean up now” button, which forcefully terminates background processes that are consuming resources. The system itself determines which applications can be safely closed and which are best left alone. Using this method is preferable to manual swiping, since the algorithms One UI know the priority of system services.
⚠️ Warning: Constantly manually clearing memory through this section may lead to faster battery drain. Android is optimized to run on full memory, and constantly restarting apps uses more power than keeping them running in the background.
You can also see a detailed breakdown of apps in this menu. By clicking on a specific app, you will see how much memory it takes up and how much data it uses. This helps to identify resource hogs that imperceptibly slow down the operation of the smartphone. Regular monitoring of this section helps keep your device in good shape.
To quickly clear memory, add the “Device Maintenance” widget to your desktop. One tap on the widget will start scanning and cleaning without requiring you to go into deep settings.
Using Developer Mode for Advanced Users
If standard tools are not enough, you can activate the hidden “Developer Options” section. To do this, you need to go to Settings → Phone information → Software information and quickly click on the “Build number” item seven times. After this, a new section will appear in the main settings menu where the professional dispatcher is located.
In the section Developer Options you need to find the item “Running services” (or “Running services”). This displays a list of all active processes in real time with an exact indication of the memory occupied. Unlike the regular menu, you can see which system services are running right now, even if they do not have a user interface.
Settings → Developer Options → Running ServicesThis tool allows you not only to monitor, but also to stop services. However, this should be done with extreme caution. Stopping critical system processes can lead to unstable operation of the interface or even cyclic reboot of the device. Use this feature only if you know exactly what a particular service does.
- 🔧 Activate the developer menu with seven taps on the build number.
- 👁️ The "Running Services" section shows active processes in real time.
- 🛑 Stopping services here affects the system more deeply than usual. closing.
What happens if you stop the Android system service?
Stopping key services, such as System UI or Google Play Services, can lead to the disappearance of the status bar, loss of connection with the account, or a complete freeze of the smartphone, requiring a reboot using the power and volume buttons.
Special codes and Samsung engineering menu
There is another level of access to diagnostics, available through a set of special USSD codes in the “Phone” application. By entering the combination *#9900#, you will be taken to the system debugging menu SysDump. Although the direct task manager is rarely located there, this section allows you to clear logs and manage low-level memory parameters.
More useful for managing tasks may be the code #0#that opens the hardware testing menu. Although it is intended for testing screens and sensors, in some firmware versions it can be used to access information about CPU and RAM load in real time. This is useful for diagnosing hardware problems when the phone slows down for no apparent reason.
Changing unknown parameters in sections Low RAM Debug or similar may lead to a software failure. If you are not sure of the purpose of the item, it is better not to touch it.
⚠️ Attention: The engineering menu interface may differ depending on the Android version and regional firmware. Some codes may be blocked by your carrier or manufacturer. Do not change the values if you do not understand their functions.
Comparison of task management methods
Having understood all the methods, it is useful to systematize knowledge in order to understand which method is more effective in a particular situation. Different approaches give different results: from simple visual cleaning to deep analysis of resource consumption.
| Access method | Cleaning depth | Security | What is best for |
|---|---|---|---|
| Menu of running applications | Low | High | Quickly closing frozen windows |
| Device maintenance | Medium | High | Daily memory optimization |
| Developer options | High | Medium | Memory leak diagnostics |
| Engineering menu (codes) | Maximum | Low | Professional debugging |
As can be seen from the table, the first two methods are sufficient for everyday use. They provide a balance between system performance and stability. Deep methods should be used only when specific problems arise that cannot be solved by standard means.
The Android system independently manages memory more efficiently than the user. It is worth interfering with the work of the dispatcher only in case of obvious performance problems or freezes.
Alternative solutions and third-party software
If the built-in capabilities are not enough, users often turn to third-party applications from Google Play Store. apps like Greenify or Files by Google offer more flexible settings for process hibernation. They can automatically “freeze” applications that you rarely use, preventing them from running in the background.
However, with the release of new versions of Android (starting from 10 and higher), the rights of third-party managers have been significantly limited for security purposes. They can no longer force processes to close as effectively as system tools. Therefore, you shouldn’t rely on them as a panacea.
The best strategy remains to properly configure the smartphone itself. Disabling unnecessary synchronization, limiting background activity for heavy applications and timely software updates have a greater effect than constantly fighting running processes through third-party software.

Frequently asked questions (FAQ)
Why is there no separate “Manager” button on Samsung tasks"?
In modern versions One UI task manager functionality is integrated into the menu of open applications and the device maintenance section. A separate application has been removed to simplify the interface and prevent inexperienced users from accidentally closing important system processes.
Is it harmful to constantly close all applications?
Yes, it can be harmful. Android is designed to keep frequently used apps in memory for quick launch. Constant forced cleaning forces the processor to reload these applications, which increases battery consumption and creates unnecessary load on the drive.
How to find out which application is eating up the most memory?
Go to Settings → Device Maintenance → Memory. There you will see a graph and a list of applications sorted by the amount of RAM used. You can also find detailed statistics in the “Battery and Performance” section.
Is it possible to increase RAM on Samsung programmatically?
It is impossible to physically increase RAM, but many modern Samsung models support the function RAM Plus. It allows you to use part of the device's internal memory as virtual RAM. You can find this option in the device maintenance settings if your model supports this technology.
