Many smartphone owners Samsung face a common problem: after updating the firmware, the familiar “Application Manager” icon disappears from the screen or stops working as before. This is puzzling, because the tool is necessary to control running processes and free up RAM. In fact, in modern shells One UI the company has changed the approach to resource management, making it more automated, but less obvious to the user.
However, access to system monitoring utilities has not gone away. It was simply moved deeper into the settings or integrated into other device maintenance services. In this article, we'll take a closer look at where exactly to look for task management tools on various Galaxy models, from the budget A series to the flagship S and Note. You will learn not only to find the menu, but also to correctly interpret data about the operation of RAM and background processes.
Understanding the architecture of Android on Korean brand devices will help you avoid installing dubious cleaning apps from third-party stores. Often built-in tools work more efficiently and are safer for the battery. We will look at both standard access paths through settings and engineering methods for calling hidden menus for advanced users who want to gain full control over their gadget.
Evolution of memory management in the One UI shell
Previously, Samsung smartphones had a separate section in the application menu, which was called “Device Manager” or “Application Manager”. It allowed you to close all apps in one click and see a graph of resource usage. With the release of the shell One UI the philosophy has changed: the system now decides itself which processes to keep in the background for quick startup, and which to terminate to save energy.
Modern optimization algorithm works differently. Instead of manually closing tabs, the user is offered a comprehensive “Device Optimization” function. It analyzes the health of the battery, storage and RAM, offering a single solution to problems. However, for those who are accustomed to manual control, the ability to view active applications remains available, it’s just that the path to it has become longer.
It is worth noting that aggressively closing all background processes can even harm performance. The system is forced to reload heavy applications into memory, which consumes more processor power. Therefore Forcibly stopping system services through the engineering menu can lead to unstable operation of the interface, and this should be done only in case of obvious freezes.
⚠️ Attention: The menu interface may vary slightly depending on the version of Android and the specific model of your smartphone. If you do not find the item in the specified location, use the search in the settings.
The standard path through the device settings
The safest and recommended way to check the system load is to use the built-in maintenance menu. It provides reliable information without the risk of accidentally deleting important system files. To get there, you need to go to the main settings of your device.
Find the section in the list Device Maintenance (on some firmware it may simply be called “Device Care”). Inside this menu, you will see summary information about the battery, storage, and memory. By clicking on the item Memory (or RAM), you will be taken to a detailed report on how many gigabytes are free and how many are occupied by current tasks.
A button is also available here Clear now, which terminates background processes that are not critical to the operation of the system. This is an analogue of the good old dispatcher, but with a smarter approach. The system itself will determine which applications can be closed and which are better left so as not to disrupt notifications or synchronization.

Device Maintenanceat the bottom of the list or at the top, depending on the version of One UI. - 💾 Click on the icon
Memoryto view RAM usage details. - 🧹 Use the
Clear Nowbutton to end background tasks.
If the “Clear Now” button is inactive, then the system has already optimized the memory, and manual intervention is not required.
Using developer mode for detailed control
For users for whom the standard menu is not enough, there is an advanced tool - developer mode. It opens access to the real Task Manager, where absolutely all processes are displayed, including system services. Activating this mode requires performing a few simple steps in the About Phone menu.
You need to find the item Build number in the Phone information section and quickly click on it seven times. After entering the screen unlock PIN, the system will inform you that the developer mode is activated. A new section will appear in the main settings menu Developer options, usually located at the very bottom of the list.
Inside this section, find the item Running services (or "Running Services"). This is the very powerful tool that shows detailed information about each running process: how much memory it takes up, how long it runs and what components it uses. Here you can force stop any application by clicking on it and selecting the appropriate option.
Settings → Phone information → Build number (7 clicks) → Developer options → Running servicesBe extremely careful when using this menu. Stopping the service Android System or display drivers may result in an emergency reboot of the device or temporary loss of communication. Use this feature only if you know exactly which process is causing the problem.

Analysis of RAM and cache operation
Understanding how memory works on Android is critical for proper operation of the smartphone. Many users mistakenly believe that free memory is always a good thing. In fact, unused RAM is wasted resource capacity that you paid for when you bought the device.
The system Android deliberately fills free space with a cache of frequently used applications so that they open instantly. When you launch a heavy game, the system automatically offloads the least important background tasks, freeing up space. Therefore, constant manual cleaning through the dispatcher often does not make sense and only irritates the user.
Nevertheless, there are situations when cleaning is necessary. For example, if some application is frozen and consumes an abnormally large amount of resources, or if you notice strong heating of the case without an active load. In such cases, using Samsung's built-in tools allows you to quickly identify the culprit and fix the problem.
| Memory type | Purpose | Recommendation |
|---|---|---|
| RAM (RAM) | Storage of active applications | Do not clear unless necessary |
| Application cache | Temporary data for quick launch | Can be cleared if there is not enough space |
| Internal storage | Photos, videos, installing apps | Keep at least 10-15% free |
⚠️ Attention: If you see that a particular application is consuming more than 1 GB of RAM in the background and is not a game or navigator, this may indicate a memory leak or malicious code.
Third-party alternatives and built-in widgets
If standard methods seem too hidden to you, you can bring memory information to the main screen. The One UI shell provides special widgets that display memory status in real time. This allows you to control the situation without going deep into the settings menu.
To add a widget, hold down an empty space on the desktop and select Widgets. Find the block Device maintenance in the list and drag it onto the screen. Now you always have before your eyes a button for quick optimization and a system load indicator. This is the most convenient way for those who like visual control.
As for third-party applications from Google Play, such as Clean Master or analogues, their use on modern Samsung is not recommended. They often duplicate system functions, but do so less efficiently, while consuming their own battery power and displaying intrusive advertising. Samsung's built-in algorithm already contains all the necessary protection and cleaning mechanisms.
Why shouldn't you install third-party cleaners?
Third-party cleaning applications often work on the “found-deleted” principle, without taking into account the operating logic of Android. They may close important synchronization services, which is why you will not receive notifications from instant messengers or email until the next manual launch. In addition, such apps themselves live in the background, consuming resources that they are supposed to save.
Solving problems with freezes and slowdowns
If you are looking for an application manager because the phone has started to work slowly, simply clearing the memory may not help. Often the reason lies in full storage or outdated software. Check how much free space is left on the internal drive - less than 2-3 GB is considered a critical threshold.
You should also pay attention to startup. In developer mode or in special battery settings, you can limit background activity for rarely used apps. This will prevent them from starting without your knowledge and save battery power. The function is called Limiting background activity or Sleep mode.
In extreme cases, when the device is unstable even after all optimizations, a reset may be required. But before that, be sure to back up your data. Remember that software failures are sometimes treated only by completely reinstalling the system through Recovery mode.
- 🔋 Check the section
Batteryfor applications with abnormal energy consumption. - 🗑️ Remove unused ones apps and large media files to free up space.
- 🔄 Update the software to the latest available version in the settings.
- 🛡️ Scan the device with the built-in antivirus through the maintenance menu.
The most common cause of slowdowns is not a lack of RAM, but full internal storage or outdated Firmware version.
Frequently asked questions (FAQ)
Why is there no “Close All” button in the multitasking menu on my Samsung?
In the latest versions of One UI, Samsung has removed this button from the standard interface to encourage users to rely on automatic system optimization. However, you can return this function by installing the special Good Lock application with the Home Up module from the Galaxy Store, or using the device maintenance widget described above.
Is it possible to delete a system process through the task manager?
No, critical system processes are protected from being forced to stop using the usual methods. Even in developer mode, attempting to stop the system kernel will only result in an instant reboot of the service or the entire phone. This is done to protect the stability of Android.
How often do you need to clear RAM on a Samsung?
Modern smartphones do not require regular manual memory clearing. Do this only if you notice clear signs of unstable operation: the interface freezes, overheating, or applications refuse to open. In everyday use, entrust this task to automation.
Where can I find the battery and application usage log?
A detailed log is in the Settings → Device maintenance → Batterysection. There you will see a graph of energy consumption and a list of applications sorted by resource consumption over the last 24 hours or 7 days.
