The question of where to find the RAM of an Android phone often arises among users who are faced with a slowdown in the device or before buying a used gadget. RAM (RAM) plays a critical role in multitasking, determining how many applications can run simultaneously without rebooting. Modern smartphones offer many diagnostic methods, from simple settings menus to in-depth analysis through system commands.
Manufacturers often use marketing ploys by indicating general characteristics on the box, which may not coincide with the actual available system resources due to reserved space for firmware. Understanding the real volume RAM helps to correctly assess the potential of the device and avoid disappointment when intensively using heavy games or work tools.
In this article we will analyze in detail all available verification methods: from standard sections of the interface to the use of specialized software and debugging bridges. You will learn how to distinguish the physical amount of memory from a virtual expansion and what indicators are the norm for different price segments.
Checking through standard system settings
The easiest and safest way to find out the volume RAM is to use the built-in interface. However, the location of this item greatly depends on the version of Android and the manufacturer's shell. In “pure” Android, information is often hidden in the “About Phone” section, while in custom firmware it is placed in a prominent place.
For devices based on stock Android or a system close to it (for example, Motorola, Nokia, Pixel) you need to go to the menu Settings → About phone. Basic information about the processor and storage capacity is usually displayed here, but RAM information may be hidden deeper. Try finding the “Device Features” item or tapping the build number several times to activate developer mode if there is no direct display.
Owners of smartphones with MIUI (Xiaomi), One UI (Samsung) or ColorOS (Oppo) skins have an advantage. In these systems, information about workload RAM is often available in real time. For example, in MIUI you need to go to Settings → About phone → All characteristics, where the total volume and current usage will be indicated.
⚠️ Attention: In some versions of Android 12 and 13, manufacturers have removed direct access to detailed memory data from the "About" menu phone" in order to simplify the interface. If you don't find the numbers, try using other methods from this article.
You should also pay attention to the “Memory” or “Storage” section in the settings. Although it most often refers to the internal storage (ROM), in some shells it displays a graph of RAM usage over the last 3 hours or day. This is useful for analyzing memory leaks, but does not always show the full physical volume.
If the settings indicate a volume less than that stated by the manufacturer (for example, 5.8 GB instead of 6 GB), this is normal. Part of the memory is reserved by the system for the operation of the kernel and hardware drivers.
Using the developer menu for detailed diagnostics
Developer mode is a hidden section of the system designed for debugging applications, but it also provides excellent access to technical information. Activation of this mode is universal for most Android devices. You need to go to Settings → About phone and find the “Build number” item.
Click on “Build number” 7 times in a row. The system will display a message stating that you have become a developer. After this, a new section will appear in the main settings menu System → For developers (or simply “For Developers”). This is where resource monitoring tools are hidden.
Inside the developer menu, find the “Memory” or “Memory Usage” item. Not only the total volume is displayed here, but also detailed statistics: how much is occupied by the system, how many by applications, and the average amount of free memory for the last 3 hours, 6 hours or day. This allows you to identify parasitic applications that consume excessive resources.
- 📊 Average usage: shows the load on the system over time.
- 🧹 Clear button: allows you to force the process cache to be cleared (use with caution).
- ⚙️ Services: list of system services that take up space in RAM.
It is important to understand that enabling developer mode does not affect the warranty, but changing other parameters in this menu (for example, the limit of background processes or animation speed) may lead to unstable operation of the phone. Be careful when navigating.
☑️ Activating developer mode
Third-party applications for analyzing characteristics
If the built-in tools do not provide a complete picture or the interface is too confusing, specialized utilities from Google Play come to the rescue. These applications read data directly from kernel system files, providing the most accurate information about the hardware, including memory type (LPDDR4X, LPDDR5) and frequency.
One of the most popular and reliable tools is CPU-Z. After installation, launch the application and go to the Device or RAMtab. Here you will see the total amount of available memory, current real-time usage and technical specifications of the chips.
Another decent option is AIDA64. It's a diagnostic powerhouse that shows not only RAM, but also sensor temperatures, battery health, and detailed display data. The section Memory displays the total volume, free space and percentage used.
| Application | Data accuracy | Availability of advertising | Additional. functions |
|---|---|---|---|
| CPU-Z | High | Minimum | Benchmark, sensor monitoring |
| AIDA64 | Maximum | Absent (in paid version) | Diagnostics of network, batteries, OS |
| DevCheck | High | Yes | Real-time monitoring, widgets |
Using third-party software is convenient because the data is presented in a structured form, understandable even to an inexperienced user. In addition, many of these applications have desktop widgets that allow you to monitor the loading RAM without going to the menu.
Engineering menu and hidden codes
For advanced users, there is access to the engineering menu through special USSD codes. This method allows you to access hidden radio module settings and hardware tests. However, be extremely careful: changing unknown parameters may lead to loss of connection or reset of network settings.
The most universal code for entering the testing menu is ##4636##. After entering this combination in the Phone application, the Test menu will automatically open. Select Phone Information. The network status is often displayed here, but some firmware has tabs with memory information.
The codes may differ for devices of different brands. For example, the code often works on Samsung #0# for a general test, and on Xiaomi - ##6484##. In these menus you can run a memory test, which will check the cells for errors and show the total volume.
⚠️ Attention: The engineering menu interface depends on the processor model (Snapdragon, MediaTek, Exynos). On some newer models, access to these codes may be blocked by the manufacturer for security reasons.
If the code does not work or the message “Connection is invalid” is displayed, then your firmware is restricting access to these functions. In this case, it is better to use the applications from the previous section, since forcibly hacking the engineering menu via ADB requires root access.
What to do if the codes do not work?
If standard codes do not open the menu, try installing the "QuickShortcutMaker" application. It allows you to find and launch hidden system activities, including engineering menus, by their internal package name, bypassing a set of codes.
Checking through a connection to a computer (ADB)
The most professional and reliable way to find out the volume RAM is using the Android Debugging Bridge (ADB). This method does not require installing unnecessary applications on the phone and shows “honest” data that the system kernel sees, ignoring marketing shell add-ons.
First, you need to enable USB debugging in developer mode (as described in the second section) and connect the phone to the PC with a cable. ADB drivers must be installed on your computer. Open a command line or terminal in the platform tools folder.
Enter the following command to get detailed memory information:
adb shell dumpsys meminfoAt the beginning of the output you will see a line Total RAMthat will show the total amount in kilobytes. To convert to megabytes, divide the value by 1024. This method will also show how much memory is occupied by each specific process, which is useful for finding leaks.
An alternative option is the command adb shell cat /proc/meminfo. It outputs raw data from the kernel virtual memory file. The line MemTotal will show the physical volume of the installed RAM chip. This is the most accurate value, since it is read directly from the memory controller.
- 💻 PC is required: a computer with SDK Platform Tools installed is required.
- 🔌 Cable: use a quality cable for a stable connection.
- 🛡️ Security: the method does not require root access and is safe for data.
The use of ADB is especially important when purchasing used devices, when there is a suspicion that the memory volume has been changed by software (so-called “fake” smartphones). The system will show the real value, regardless of what is written in the interface settings.
The ADB command reads data directly from the memory controller, so this is the only way to find out the real physical amount of RAM, which cannot be faked programmatically in the settings.
Virtual memory expansion: how not to get confused
In modern smartphones of medium and In the budget segment, the technology of virtual expansion of RAM is popular. Marketers call it differently: Samsung, Xiaomi, Realme. The essence of the technology is to use part of the read-only storage (ROM) as slow RAM. RAM Plus from Samsung, Memory Extension from Xiaomi, Dynamic RAM from Realme. The essence of the technology is to use part of the read-only storage (ROM) as slow RAM.
When you look at the characteristics in the settings, you may see a strange amount, for example, “8 GB + 4 GB”. It's important to understand that the extra 4GB is not a physical RAM chip, but a dedicated page file on flash memory. The speed of such memory is significantly lower than that of real LPDDR5.
Diagnostic applications such as CPU-Z usually show only the physical size (8 GB in this example), ignoring the virtual expansion. However, the Android system settings may display the total value. This often misleads users when assessing device performance.
⚠️ Attention: Virtual memory does not replace physical RAM for heavy-duty tasks. It only helps to keep more background applications running, but does not speed up the processor. For games, it is the physical volume that is critical.
To see the real picture, always focus on the data from the engineering menu or ADB, where only the hardware installed on the board is indicated. Virtual expansion can be disabled in the settings if you notice that it slows down the drive due to constant overwriting of cells.
The technology is useful for devices with 4 GB of physical memory, allowing them to multitask more comfortably. But on flagships with 12 GB or more, its effect is almost unnoticeable, and in some cases it can even reduce the overall responsiveness of the system due to the way the memory controller works.
If your phone starts to slow down after enabling the memory expansion function, try disabling it in the settings. The speed of the internal flash memory may not be sufficient for comfortable operation as RAM.
Frequently asked questions (FAQ)
Why is less memory shown in the settings than stated on the box?
Part of the RAM is reserved by the system for running the Android kernel, hardware drivers (video accelerator, modem) and security. For example, out of 6 GB of physical memory, about 5.5–5.8 GB are available to the user. This is normal practice for all devices.
Is it possible to increase the physical RAM on the phone?
No, the RAM chips are soldered directly to the motherboard or integrated into the processor (PoP). It is impossible to replace them or add new modules at home. Only software virtual expansion is available using internal memory.
How to find the type of RAM (LPDDR4 or LPDDR5)?
This information cannot be found in the standard Android settings. Use applications like CPU-Z or AIDA64 by going to the “System” or “RAM” tab. The type of chips and their frequency will be indicated there.
Does the amount of RAM affect the charging speed of the phone?
There is no direct effect. Charging speed depends on the power controller, battery capacity, and support for fast charging standards. However, a larger amount of RAM allows you to more effectively manage background processes, which can indirectly affect power consumption in standby mode.
Is it true that clearing RAM through “accelerators” is useful?
In modern versions of Android this is often harmful. The system itself effectively manages memory. Forcibly closing applications forces the processor to waste energy on restarting them, which leads to rapid battery drain and slow operation.
