Smartphone owners Samsung often face the need to find out the exact volume RAM (RAM) of their device. This information is critical when buying a used gadget, diagnosing performance, or trying to solve an application freezing problem. Unlike internal memory, which is easy to check in the standard menu, RAM data is sometimes hidden from a superficial glance or displayed in a non-obvious way.
Modern shells One UI provide users with ample opportunities to monitor system resources, but the path to this data may vary depending on the version of Android and the specific phone model. Understanding how much memory is available to the system in real time, and not just the volume declared by the manufacturer, helps to competently configure the operation of background processes.
In this article we will analyze in detail all the available ways to view the characteristics of RAM on smartphones Samsung Galaxy. We will look at both standard system tools and hidden engineering menus, and also discuss why the actual amount of available memory may differ from that stated in the specifications.
Checking through standard system settings
The easiest and safest way to find out the amount of memory is to refer to the built-in settings menu. Depending on the firmware version One UI, the location of the items may differ slightly, but the logic remains the same. Typically, information about the hardware configuration is located in the "About phone" or "Phone information" section.
First, open the application Settings and scroll the list to the very bottom. Find item Phone information. Here you will see basic information: device model, build number and Android version. However, the amount of RAM is not always clearly displayed here. In some versions of the interface, you need to click on the line RAM or RAMif it is listed as a separate item.
If there is no direct link, try going to section Device Maintenance (or Device Care). This menu often displays the current memory usage in the form of a pie chart. By clicking on this widget, the system can show the total amount of installed RAM and the amount of free memory at the moment. This gives an idea not only of the characteristics, but also of how efficiently the system manages resources.
⚠️ Attention: The built-in settings menu can only show the total amount of memory, without displaying the exact amount of free RAM in megabytes in real time without additional clicks.
It is worth considering that part of the RAM is reserved by the system for the operation of the kernel and drivers. So even if you have 8GB installed, the system may show around 7.2–7.5GB available. This is a normal situation for the architecture Android, and it does not indicate a malfunction.
If there is no information about RAM in the "Phone information" section, try clicking on the "Build number" item several times in a row - this may activate additional diagnostic menus.
Using the engineering menu and USSD codes
For deeper diagnostics, engineers Samsung have provided a hidden service menu, which can be accessed through a special combination of numbers in the dialer. This method works on most brand devices and allows you to see detailed technical information, including the exact amount and type of memory used.
Open the application Phone and go to the dialing tab. Enter the following combination: #0#. Immediately after entering the last star, a white menu should open with many buttons for testing the screen, sensor and sensors. To view memory information, this path is not always directly suitable, so try an alternative code: *#9900#.
Code #9900# opens the menu SysDump. Here the list of options is much more extensive. You need to find an item related to system information or memory. Often the necessary data is in the section Copy to sdcard (creating a log), but for quick viewing it is better to use the code #1234#. This combination displays three lines on the screen: AP (firmware version), CP (modem) and CSC. Although this code is more about the software version, it confirms the authenticity of the device, which indirectly guarantees compliance with the declared memory.
The most informative for checking the hardware is often the code *#0228#, which opens the battery status menu, but may also contain tabs with information about the system. However, the most reliable "memory code" may differ between older and newer models. If the standard codes did not work, it is possible that your telecom operator or firmware region has blocked access to these functions.
Why may the codes not work?
Some telecom operators change the standard "Phone" application to their own, blocking the entry of USSD service codes. In this case, try installing a third-party dialer from the Play Market, for example, True Phone, and enter the code through it.
Be careful when navigating through the engineering menu. Changing parameters in sections marked as Write or Debugmay lead to unstable operation of the smartphone. Your goal is only to view information (Read/Status).
Developer menu for detailed monitoring
If standard methods do not provide a complete picture, the most powerful tool is the developer menu. This section is hidden by default to prevent inexperienced users from accidentally changing critical system settings. Activating this mode provides access to process statistics and a detailed usage report RAM.
To activate the mode, return to Settings → Phone information → Software information. Find the item Build number and quickly click on it 7 times in a row. The system will ask you to enter your PIN code or pattern, after which a notification “Developer mode is enabled” will appear.
Now in the main menu settings, usually at the very bottom or in the "System" section, a new item will appear Developer options. Go into it and find the section Memory or Services (in some versions of Android this is called "Running services" or "Running services"). By clicking on this item, you will see a list of all active processes and the exact amount of memory that each of them occupies.
- 📊 Total memory: Displays the physical amount of RAM installed on the board.
- 📉 Available: Shows the free space that can be allocated to new applications.
- 🔄 Cached: The amount of memory occupied by background processes for quick startup.
Here you can also see the average running time of processes and understand which application “eats” the most resources. This is valuable information for optimizing the operation of the device. If you see a process that takes up an abnormally large amount of space and is not a system process, it may be time to delete or limit it.
☑️ Activating Developer Mode
⚠️ Attention: Do not disable processes with namesandroid.system,com.samsungorcom.androidforcedly through this menu. This may lead to the phone rebooting or data loss.
Third-party diagnostic applications
When the built-in tools are not enough or the interface seems too complicated, specialized utilities from the store come to the rescue. Google Play. These applications collect data from all sensors and system logs, presenting them in a convenient visual format. They often show information that the manufacturer has hidden in deep menus.
One of the most popular and reliable solutions is the application CPU-Z. It is free, does not contain intrusive advertising and provides comprehensive information. After installation, launch the app and go to the Device (Device) tab. In the section Memory (Memory) you will see a line Total RAM, which will show the exact volume in megabytes or gigabytes.
Another useful application is AIDA64. It provides an even more detailed technical summary, including memory type (LPDDR4X, LPDDR5), operating frequency, and dual-channel mode. This is especially important for enthusiasts who want to know not just “how much,” but also “what kind of” memory is installed in their Samsung Galaxy.
| Application | APK size | Main function | Presence of advertising |
|---|---|---|---|
| CPU-Z | ~5 MB | Info about the processor and RAM | Minimum |
| AIDA64 | ~10 MB | Full system diagnostics | Yes (in) |
| DevCheck | ~8 MB | Real-time monitoring | Yes |
| 3C Toolbox | ~15 MB | Memory management and clearing | Yes |
Using third-party software has one undeniable advantage: these applications show not only static volume, but also the dynamics of load changes in real time. You can run a heavy game and immediately see on the graph how RAM consumption is growing.
Third-party applications like CPU-Z often show more accurate data about the type and frequency of memory than the standard Android settings menu.
Why is the available memory less than declared
Many users wonder: "Where did my gigabytes?" If you bought a phone with 6 GB of RAM, and the system shows that only 4.5 GB is available, this is not an error or deception of the manufacturer. The architecture of modern mobile operating systems requires the allocation of a significant portion of resources for their own needs.
The system kernel Linuxon which Android is based reserves memory for the operation of hardware drivers: modem, graphics accelerator (GPU), display and cameras. This memory area is not available for user applications, as it is necessary for stable operation of the hardware. The higher the screen resolution and the more powerful the camera, the more memory can be reserved for these needs.
In addition, part of the RAM can be used by technology RAM Plus (or similar solutions from other brands), which allocates part of the internal flash memory for virtual RAM. In some cases, this can distort the display of total capacity in diagnostic utilities if they do not correctly separate physical and virtual memory.
It is also worth considering the difference between decimal and binary number systems, although in the case of RAM this effect is minimal compared to internal memory. Manufacturers consider 1 GB as 1000 MB, and the system often operates with the concept of 1024 MB, which creates a slight mathematical error in the display.
Optimizing and managing RAM
Knowing the amount of memory is only the first step. It is important to be able to properly manage this resource. Smartphones Samsung have a built-in optimization function that automatically closes unnecessary applications and clears the cache. However, sometimes manual intervention is required.
If you notice that the phone has started to work slowly and there is critically little free memory, do not immediately panic. First, check which apps are running in the background. In the developer menu, which we talked about above, you can see “gluttonous” apps. Often the culprits are social networks or instant messengers that incorrectly release resources.
For advanced users, it is possible to limit background processes. There is an item in the developer menu Background process limit. By default there is “Standard limit”, but you can select “No more than 2 processes”. This will strictly limit the number of applications remaining in memory after minimizing, which will free up a significant amount of RAM for the active task.
However, be prepared for the fact that if you strictly limit background processes, notifications from instant messengers may arrive with a delay, and switching between applications will lead to a complete reboot. The balance between free memory and ease of use is a key point in setup.
⚠️ Attention: The developer menu interface and available options may vary depending on the Android version and regional firmware. If you do not find the described item, check the official manual for your model.
Frequently asked questions (FAQ)
Why does the settings say 8 GB, but the apps show 7.4 GB?
This is normal. Part of the RAM is reserved by the system kernel and hardware components (video core, modem) for their stable operation. User applications do not have access to this reserved area.
Is it possible to increase RAM on a Samsung?
It is impossible to physically increase the amount of memory soldered on the board. However, many modern Samsung models support a function RAM Plusthat uses part of the internal flash memory as virtual RAM, which can help when there is a lack of resources.
Does the amount of RAM affect the speed of the phone?
Yes, directly. The more free RAM, the more applications can run simultaneously in the background without rebooting. When there is not enough RAM, the system begins to use swap files on slow internal memory, which causes brakes.
How to find the type of memory (LPDDR4 or LPDDR5) without a computer?
The easiest way is to install the application CPU-Z or AIDA64. On the "Device" or "System" tab, in the Memory Type field, the exact type of installed memory chip will be indicated.
Why is there less free memory after updating Android?
New versions of the operating system often become more resource-demanding, adding new background services and security features. This is a natural process of software evolution, which may require more RAM for comfortable operation.
