Where to find RAM on Android: a complete guide with pictures and commands

Please note: on some devices (especially budget ones) Manufacturers can hide the real amount of RAMby specifying only “available” memory. For example, instead of 4 GB you will see 3.5 GB - this is normal since some memory is reserved for the system. If the figure is greatly underestimated (for example, 2 GB instead of the stated 4 GB), this is a reason to check the smartphone for authenticity - perhaps they sold you a “reflashed” device.

2. Hidden engineering mode menus: data for advanced users

If the standard settings do not show the necessary information (or you suspect that the manufacturer has hidden the real characteristics), you can look into Engineering menu. This is a hidden section where the technical data of the device is displayed, including detailed information about the RAM. Warning: Do not change the parameters in this menu if you are not sure of their purpose!

To open the engineering menu, do the following steps:

1. Open the application Phone.
2. Enter the combination: ##4636## (for most devices) or #0# (for Samsung).
3. Select "Phone information" or "Hardware Info».
4. Scroll down to the block "Memory" - the current usage will be indicated here. total amount of RAM and current use.

On some devices (for example Huawei or Honor) the engineering menu may be blocked. In this case, try alternative codes:

• 🔢 For Huawei/Honor: ##2846579## → «ProjectMenu» → «Background Settings» → «Memory Info».
• 🔢 For Sony Xperia: ##7378423## → «Service info» → «Memory».

Attention! The engineering menu displays real hardware characteristics, which may differ from those declared by the manufacturer. For example, if you bought a smartphone with 6 GB. RAM, but here you see 4 GB - this is a sign of fraud (perhaps the seller replaced the memory board or flashed the device for a different model).

3. Applications for monitoring RAM: top 5 utilities from the Play Market

Standard settings and the engineering menu show only static data. But how can you find out which applications are “eating” it, and is it time to close unnecessary processes? To do this, you will need specialized utilities. We have selected 5 proven applications that will not only show the amount of RAM, but also help optimize its use. how much memory is being used directly. now, which applications are “eating” it, and isn’t it time to close unnecessary processes? To do this, you will need specialized utilities. We have selected 5 proven applications that will not only show the amount of RAM, but also help optimize its use.

Let's take these applications as an example CPU-Z:

1. Install the application. from Play Market and open it.
2. Go to the tab "Memory».
3. Pay attention to the following points:
   • 📊 Total RAM — total amount of RAM.
   • 📉 Used RAM — currently used memory.
   • 🔄 Free RAM — free memory.
   • 🔧 Type —memory type (for example, LPDDR4X or LPDDR5).

Attention! Some applications (for example, Game Booster) offer “cleaning RAM” in one click. On Android 10 and newer, forced memory clearing can lead to slowdown, since the system itself optimizes background processes. Use this function only if the smartphone is really frozen.

Check reviews (especially 1-2 stars) for advertising and bugs

Check if the application shows the memory type (LPDDR4/LPDDR5)

Make sure the utility has been updated in the last 6 months

Avoid applications that require root access to simply check RAM-->

4. ADB commands: checking RAM for developers and enthusiasts

If you are not afraid of the command line, Android Debug Bridge (ADB) is the most accurate way to get RAM data. This method is suitable for diagnosing problems when standard methods do not work (for example, on custom firmware or devices with a locked engineering menu).

First, make sure that you have installed on your PC ADBdrivers are installed on your PC, and that USB debugging (Settings → About phone → Build number is turned on on your smartphone - tap 7 times, then return to Settings → System → For developers → USB debugging).

Connect the device to the computer and execute in the terminal (or Command Prompt) the following commands:

adb shell
cat /proc/meminfo

You will receive a detailed memory report, where we are interested in two lines:

• MemTotal — total amount of RAM in kilobytes (divide by 1024 to get megabytes).
• MemFree — free memory.

For a more convenient display, use the command:

adb shell dumpsys meminfo

It will show detailed report for each process, including system services and applications. For example, you can see that Facebook occupies 500 MB, and Chrome -800 MB.

Attention! Commands ADB requires connection to a PC and USB debugging enabled. On some devices (for example, Huawei c EMUI 12+s), ADB may require additional permission in the security settings. Also be careful: incorrect commands can disrupt the system.

@echo off
adb shell dumpsys meminfo | find "MemTotal"
adb shell dumpsys meminfo | find "MemFree"
pause

Now just double-click on the file to get memory data.-->

5. Analysis of RAM usage: how to understand whether there is enough memory

Knowing the amount of RAM is half the battle. It is much more important to understand Is it enough for your tasks? whether memory is a performance bottleneck. Here are the key signs that RAM is overloaded:

• 🐢 Applications Take a long time to open or reboot when returning to them.
• 🔄 Frequent game crashes with the "Insufficient memory" error.
• 📉 In the task manager you can see that free memory is less than 10% of the total volume.
• 🔋 The smartphone gets very hot when multitasking (for example, when working simultaneously YouTube, Telegram and playing games).

How to check the current RAM load without third-party applications?

1. On Samsung: Settings → Device maintenance → Memory. There is a graph of RAM usage in real time.
2. On Xiaomi: Settings → Applications → Manager tasks (three stripes icon).
3. On Google Pixel: Settings → Memory → RAM.

If free memory is constantly less than 20%, you should take measures:

• 🚫 Close background applicationsthat do not use (especially instant messengers and browsers).
• 🔄 Reboot your smartphone every 2-3 days —this clears the cache and frees up memory.
• 📱 Disable interface animation (Settings → For developers → Animation scale (off)).
• 🗑️ Delete cache applications (Settings → Storage → Cache data).

6. Checking RAM for authenticity: how to identify the seller's fraud

Unfortunately, fraud with the characteristics of smartphones is not uncommon. Unscrupulous sellers can:

• 🔄 Flash device so that it shows inflated amount of RAM (for example, 6 GB instead of 4 GB).
• 📱 Replace the motherboard with a cheaper one (with less memory).
• 💻 Replace data in the engineering menu using special software.

How to check if you have been deceived? Here are reliable ways:

1. Compare data from different sources:
   • 📋 Standard settings (About the phone).
   • 🔧 Engineering menu (##4636##).
   • 📊 Application CPU-Z or AIDA64.
   • 💻 ADB-command cat /proc/meminfo.

If the numbers differ, this is a reason for suspicion.

Attention! If you find discrepancies in the characteristics return the device to the seller. within 14 days (according to the law “On the Protection of Consumer Rights”) To do this:

1. Take screenshots with data from different sources (settings, CPU-Z, ADB).
2. Make a video showing the smartphone model and test results.
3. Contact the seller with a request to return the money or replace the device with an original one.

7. Common mistakes when checking RAM and how to avoid them

Even experienced users sometimes make mistakes when diagnosing RAM. Here are the most common ones and how to avoid them:

• ❌ Trusting only one data source
  👉 Always check the information from the settings, engineering menu and third-party applications. For example, on some Xiaomi in the settings, 6 GB of RAM may be displayed, and in CPU-Z - 4 GB (this is a sign of deception).
• ❌ Ignoring the memory type
  👉 The amount of RAM is not the only important parameter. For example, LPDDR5 6 GB can run faster than LPDDR4X 8 GB. Check the memory type in AIDA64.
• ❌ Forced clearing of RAM
  👉 The system itself manages the memory. to Android 10+ The system manages the memory itself. Manually freeing RAM may result in slowdown, since applications will have to be rebooted from scratch.
• ❌ Using dubious “boosters”
  👉 Applications like Clean Master or DU Speed Booster often show false information about RAM and load the system with advertising. Use only proven utilities (CPU-Z, AIDA64).
• ❌ Neglecting to reboot
  👉 If the smartphone works without rebooting for more than a week, the RAM may be clogged. "garbage" processes. Reboot the device every 2-3 days.

Another typical mistake is comparison of smartphone and PC RAMOn Android, memory is managed differently: the system actively uses free RAM for caching, therefore. You will almost never see “free” gigabytes. This is normal! The main thing is that when you open new applications, the memory is freed up automatically.

FAQ: Answers to frequently asked questions about RAM on Android

Is it possible to increase the amount of RAM on Android?

Physically, no, since the memory is soldered to the motherboard. However, there are workarounds:

• 🔄 Use RAM Plus function (available on Samsung, Xiaomi, Realme). It reserves part of the internal memory for virtual RAM (for example, +2 GB from a 128 GB drive). The effect is minimal, but in some cases it helps.
• 📱 Install custom firmware with optimization for a small amount of RAM (for example, LineageOS or Pixel Experience).
• 🚀 Disable background processes and animation (in the settings for developers).

Important! Virtual RAM (RAM Plus) works slower than physical memory, as it uses the internal memory of the device. You should not expect miracles from this function.

Why does the settings show 6 GB of RAM, but in CPU-Z - 4 GB?
This is a classic sign fraud. Most likely:
• The seller flashed the device for a different model (for example, instead of Redmi Note 10 with 4 GB of RAM, he sold it as Note 10 Pro with 6 GB).
• Installed on the motherboard the memory module is smaller, and the data in the system has been replaced.

What to do:

1. Check the serial number of the device with the official database of the manufacturer (for example, on the website Mi Verify for Xiaomi).
2. Contact the seller to request a return or replacements.
3. If the purchase was through the marketplace (Wildberries, Ozon), write a complaint to support with evidence (screenshots from CPU-Z i ADB).
