In the modern world of mobile technology, processor capacity plays a key role in device performance. Users often wonder how to learn how many bits their device supports: 32 or 64. This knowledge is critically important when installing specialized software, emulators, or when trying to optimize the operation of the operating system. Many modern applications require a 64-bit architecture for correct operation and access to the entire amount of RAM.
The definition of bit depth is not always obvious from the standard settings menu. Smartphone manufacturers often hide technical details under fancy marketing model names. However, there are proven methods to identify the true architecture Central Processing Unit (CPU). We will look at methods from using simple utilities to advanced methods through the computer.
Understanding the differences between architectures will help you avoid mistakes when installing firmware or modified kernels. If you are planning root access or custom recovery, this information will become the foundation for further actions. Let's take a look at what tools will help you get an accurate answer without unnecessary complications.
Why you need to know the processor bit capacity
The main difference between a 32-bit architecture and a 64-bit one is the amount of addressable memory. 32-bit systems can theoretically run with a maximum of 4 GB of RAM, while 64-bit systems can support significantly larger amounts. If your device has 6 or 8 GB of RAM, but runs on a 32-bit core, some of the memory will simply not be available for use by applications. In addition, many modern and professional applications are moving to support exclusively 64-bit instructions. This is due to the need for faster computing and improved data security. Knowledge of the architecture allows you to understand in advance whether a smartphone can handle a new version of your favorite game or graphics editor.
In addition, many modern heavy games and professional applications are moving to exclusively support 64-bit instructions. This is due to the need for faster computing and improved data security. Knowledge of the architecture allows you to understand in advance whether a smartphone can handle a new version of your favorite game or graphics editor.
⚠️ Attention: Trying to install a 64-bit application on a 32-bit system will result in an installation error. The application store may simply not show compatible software in the search.
The bit depth also affects the choice of operating system version when flashing. Incorrectly selected firmware can turn the device into a “brick” or cause constant malfunctions. Therefore, before any manipulations with the system partition, you must clearly understand the capabilities of your hardware.
If you buy a used smartphone, be sure to check its bit capacity. Some older models with a large amount of memory may have limitations due to the 32-bit processor.
Using specialized applications
The easiest and most accessible way for the average user is to install diagnostic utilities from Google Play. There are many free apps that read information directly from the system kernel and display it in an understandable form. You do not need superuser (root) rights to perform this procedure.
One of the most popular utilities is CPU-Z. After installation, launch the application and go to the System or SoCtab. Here you will see the line Kernel Architecture or Instruction Sets. If arm64-v8ais present in the list of instructions, then your processor supports 64 bits. If there is only armeabi-v7a, then the device is limited to 32 bits.
Other reliable applications, such as AIDA64 or Device Info HWprovide even more detailed information. They show not only the overall bit capacity, but also the capabilities of each individual processor core. This is useful for devices with a hybrid architecture, where different cores can have different characteristics, although this is rare in the mass segment.
- 📱 Download CPU-Z or AIDA64 from the official application store.
- 🔍 Run the app and find the "System" or "Processor" section.
- ✅ Look for the marking
arm64to confirm 64-bit support. - 📊 Pay attention to the list of supported instructions (ABI).
The interface of such apps may differ depending on the version of Android and the manufacturer's shell. However, key terms generally remain the same in English. If you see a mention ARMv8, this is a guaranteed sign of a 64-bit architecture, since ARMv7 is a standard for 32 bits.
Checking through developer settings and About Phone
Sometimes information can be found in the standard phone settings, although manufacturers often hide it deep in the menu. Go to the section Settings → About phone. In some pure versions of Android, for example on smartphones Google Pixel or Motothe processor type may be specified. However, most often it just says the name of the chip model, for example Snapdragon 888.
To get more data, you can activate the menu for developers. To do this, you need to quickly click on the build number seven times in the “About phone” section. After activation, go to the new menu item For developers. Although there may not be direct information about the bits, sometimes logs or bug reports contain technical specifications.
This method is less reliable than using third-party software, as it requires the ability to interpret the name of the processor. You will have to google the specifications of the chip model you find. For example, if you found information that you MediaTek Helio P60, the search will confirm that it is a 64-bit chip. But for a beginner this can be difficult.
⚠️ Attention: Do not change the settings in the “For Developers” menu if you are not sure of their purpose. This can lead to unstable operation of the system.
In some shells, such as MIUI from Xiaomi or OneUI from Samsung, information about the processor may be completely hidden. In this case, it is better to immediately move on to using applications or computer diagnostics so as not to waste time searching.
Diagnostics via computer and ADB
For advanced users, the most accurate method is to use USB debugging and tools ADB (Android Debug Bridge). This method allows you to obtain “raw” data directly from the system without intermediaries in the form of graphical applications. You will need a computer with drivers and platform tools installed.
Connect your smartphone to the PC with a cable and enable USB debugging on the phone screen. Open a command prompt or terminal on your computer in the ADB folder. Enter the following command to check the supported architectures:
adb shell getprop ro.product.cpu.abiThe command will display the main architecture of the device. If the answer is arm64-v8a, then the phone is 64-bit. The answer armeabi-v7a indicates 32 bits. You can also use the command adb shell cat /proc/cpuinfowhich will display detailed information about the processor, including feature flags.
This method is convenient because it works even on devices with a broken screen or sensor problems if debugging is enabled. You are in complete control of the process of obtaining information. In addition, through ADB you can find out which libraries are installed in the system, which gives a 100% guarantee of compatibility with this or that software.
☑️ Preparing for testing via ADB
Analysis of system files without root access
If installing applications is impossible and you don’t have a computer at hand, you can use the built-in a file manager, if it allows you to browse system partitions (which is rarely accessible without root), or use simple text editors with access to some virtual files. However, on modern versions of Android, access to the system root is closed.
An alternative is to use terminal emulators directly on the phone, such as Termux. By installing this application, you will have access to the Linux command line inside Android. Enter the command uname -m. The result aarch64 means a 64-bit system, and armv7l means a 32-bit system.
This method requires minimal knowledge of the command line, but does not require a connection to a PC. Termux is a powerful tool that can be useful for other tasks, for example, for running scripts or simple servers directly on a smartphone.
| Command / Method | Result for 64 bits | Result for 32 bits | Difficulty |
|---|---|---|---|
| CPU-Z Application | arm64-v8a | armeabi-v7a | Low |
| ADB getprop command | arm64-v8a | armeabi-v7a | Medium |
| Termux (uname -m) | aarch64 | armv7l | Medium |
| CPU model search | Special. Google request | Special. Google request | High |
Using the terminal gives quick access to the system core. It is important to enter commands carefully, since an error in the syntax can lead to the utility simply not understanding the request. However, the commands uname and getprop are safe and only read data without changing it.
What is ABI?
ABI (Application Binary Interface) is an interface that defines how software interacts with the operating system and processor. Different ABIs correspond to different processor architectures.
The influence of bit depth on the choice of applications
Understanding bit depth directly affects which versions of applications you can download. On sites with APK files, you often find versions marked arm64, armeabi or universal. The universal version contains codecs and libraries for all architectures, so it takes up more disk space.
If you're downloading a heavy game like PUBG or Genshin Impact, choosing the right architecture can speed up downloads and save bandwidth. For 64-bit phones, you should choose versions arm64-v8a. This will provide the best performance since the game will use native processor instructions.
Some older applications may not work on newer 64-bit systems if the developers have not updated their code. Conversely, new apps simply won't install on older 32-bit phones. The market is moving towards a complete abandonment of 32-bit, and Google Play is already restricting the publication of new applications that do not support 64-bit architecture.
⚠️ Attention: When downloading APK files from third-party resources, always check the compatibility of the architecture. Installing the wrong version may cause the application to crash immediately after launch.
It is also worth considering that emulators of other systems (for example, Windows on Android or older consoles) require 64-bit architecture for normal operation. 32-bit emulators exist, but their performance and compatibility are significantly lower.
Choosing the correct version of the application (ARM64) can speed up its operation by 15-20% and reduce battery consumption by optimizing processor instructions.
Frequently asked questions (FAQ)
Can Can a 32-bit phone work with 6 GB of RAM?
Technically, the processor can only address about 3.2–3.5 GB of memory in 32-bit mode. The rest of the memory will either not be used by the system, or will be available only for specific tasks of the graphics core, but not for applications.
Does bit depth affect the speed of a regular interface?
On modern tasks, the difference may not be noticeable in simple operations. However, when working with archives, encrypting data or in heavy games, a 64-bit processor shows significantly greater performance thanks to an expanded set of registers.
How to find the bit depth if the phone does not turn on?
If the phone does not boot, but is detected by the computer in Fastboot or Download Mode, you can try reading the information through the appropriate utilities for Qualcomm or MediaTek processors, connected to a PC.
Are all Snapdragon 800 series processors 64-bit?
Starting with the Snapdragon 810 model and newer, all chips in this series are 64-bit. Older models, such as the Snapdragon 800 or 801, are 32-bit, despite their high performance for their time.
Is it possible to upgrade 32-bit Android to 64-bit?
No, the bit depth is determined by the physical characteristics of the processor. It is impossible to change the hardware architecture with a software update. If the processor is 32-bit, the maximum bit capacity of the system will remain the same.
