32-bit and 64-bit Android: what is the difference and why is it important for your smartphone

When you choose a smartphone or try to install a new application, you can often come across references to 32-bit or 64-bit architecture. These terms apply not only to processors, but also to the operating system itself Android. The bit depth used on your device determines its performance, compatibility with apps, and even the ability to update to new versions of the OS.

Many users mistakenly believe that 64-bit devices are simply more modern models, and 32-bit ones are outdated. In fact, the difference is much deeper: it affects data processing speed, the amount of supported RAM, and even security. In this article we will look in detail at the differences between 32-bit Android from 64-bit, how this affects the operation of the smartphone and what to do if your device does not support the desired architecture.

This topic became especially relevant after Google began to actively refuse support for 32-bit applications in Google Play. From 2019, all new applications must have a 64-bit version, and from 2021, even updates to older apps. This means that owners of older devices may encounter problems installing modern software. Let's take a look at how it works and what can be done in such a situation.

What do 32-bit and 64-bit mean in the context of Android

The terms 32-bit and 64-bit refer to processor bit and the operating system. This determines how much data the device can process in one clock cycle and how much RAM it can use.

32-bit architecture was standard for mobile devices until the mid-2010s. It allows you to address up to 4 GB RAM (although in practice less is available due to OS limitations) and processes data in 32-bit chunks. 64-bit architecture, in turn, can work with much larger amounts of memory (theoretically up to 16 EB, but on smartphones this is limited by hardware capabilities) and processes data in 64-bit chunks bit, which speeds up calculations.

It is important to understand that bit depth affects not only the processor, but and:

• 📱 Operating system — Android can be compiled for both 32-bit and 64-bit processors.
• 🎮 Applications — apps are compiled for a specific architecture (or support both).
• 🔧 Drivers and firmware —they must also correspond to the bit capacity of the device.

For example, a smartphone with a 64-bit processor can run a 32-bit version Android, but this will limit its capabilities. And vice versa: a 32-bit device physically cannot run a 64-bit OS.

Key differences between 32-bit and 64-bit Android

To understand why the 64-bit architecture has become the standard, let's look at the main differences:

Characteristics	32-bit Android	64-bit Android
Maximum amount of RAM	Up to 4 GB (in practice ~3–3.5 GB)	More than 4 GB (up to 12–16 GB on flagships)
Performance	Slower when working with large data	Faster due to processing 64 bits per clock
Application support	Only 32-bit or universal	64-bit and 32-bit (via emulation)
Security	Vulnerabilities due to outdated mechanisms	Support for modern protocols (for example, ASLR)
OS updates	Limited support for new ones versions	Full compatibility with the latest updates

Critical point: from 2021, Google Play requires all new applications to have a 64-bit version. This means that 32-bit devices will not be able to install many modern apps, even if they are physically capable of running them.

Another important difference. — emulation. 64-bit processors can run 32-bit applications through the compatibility layer, but the opposite is not possible: a 32-bit processor will not be able to execute 64-bit code. This leads to the fact that owners of older devices gradually lose access to new functions and games.

⚠️ Attention: Some manufacturers. (for example, MediaTek and Qualcomm) produced 64-bit processors, but installed 32-bit firmware on them to save resources. Such devices can be flashed to a 64-bit OS, but this requires technical skills and can lead to loss of warranty.

How to find the bitness of your Android device

Before worrying about compatibility, you need to determine what architecture is used on your smartphone. You can do this in several ways:

Method 1: Through the system settings

On most devices, the bitness can be found in the information about processor:

1. Open Settings → About phone.
2. Find item Processor model or Hardware information.
3. If the name contains x86_64, ARM64 or aarch64 it is a 64-bit architecture. If ARMv7, x86 or simply ARM it is most likely 32-bit.

Method 2: Using applications

Utilities like CPU-Z or AIDA64 show detailed information about the processor, including bit depth. For example, in CPU-Z you need:

1. Open tab SoC (system on chip).
2. View line Instruction Set (set of instructions).
3. If specified ARMv8 or ARM64 is a 64-bit processor.

Method 3: By smartphone model

You can find the technical specifications of your model on sites like GSMArena or DeviceSpecs. Usually the bit depth is indicated in the Chipset or CPUsection. For example:

• 📱 Samsung Galaxy S5 (Exynos 5422) — 32-bit.
• 📱 Xiaomi Redmi Note 4 (Snapdragon 625) — 64-bit.
• 📱 Google Pixel 3 (Snapdragon 845) — 64-bit.

⚠️ Attention: Some budget smartphones (especially those on MediaTekmay have a 64-bit processor, but 32-bit firmware. In this case, applications will see the device as 32-bit, although the hardware supports 64. bit.

Application compatibility: why 32-bit devices are becoming a problem

The main problem of 32-bit devices is lack of support for modern applicationsFrom August 1, 2019 Google obliged developers to provide 64-bit versions of new applications in Google Play. And from August 1, 2021, this requirement extended to updates of old apps. This means that:

• 🚫 New games (for example, Genshin Impact, Call of Duty Mobile) will not be available for installation on 32-bit devices.
• 🔄 Older applications (for example, WhatsApp, Facebook) may no longer be updated.
• 🛑 Some system updates (for example, switching to Android 12+) may be are not available.

At the same time, 64-bit devices are backward compatible. with 32-bit applications thanks to emulation. That is, if you have a smartphone with a 64-bit processor, you can run old apps without problems.

Real life example: game PUBG Mobile stopped supporting 32-bit devices in 2020. Users of old smartphones (for example Samsung Galaxy S3 or Xiaomi Redmi 1S) can no longer update or install the game, even if their hardware is theoretically capable of running it.

What to do if the required application is not installed?

If the application is not available on Google Play due to its bit capacity, you can try:

1. Download APK from a third-party source (for example, APKMirror), but it is not secure.

2. Use an Android emulator on your PC (for example, BlueStacks).

3. Update the firmware to 64-bit (if supported).

4. Buy a new smartphone with 64-bit architecture.

Performance: how much faster is 64-bit Android

The transition to 64-bit architecture brought not only support for more RAM, but also increased performance. Here are the key improvements:

• ⚡ Faster calculations - processing 64 bits per clock instead of 32 allows you to speed up work with large numbers (important for games, video editing, encryption).
• 🧠 Improved multitasking - thanks to support for more RAM the device can hold more applications in memory without freezing.
• 🔒 Modern security instructions —for example, ARMv8 supports ASLR (address space randomization), which makes it more difficult to exploit vulnerabilities.
• 🎮 Support for modern graphics APIs —for example, Vulkan, which requires a 64-bit architecture for full operation.

In practice, the difference is noticeable in:

• 📱 Games — 64-bit versions PUBG Mobile, Free Fire or Genshin Impact work smoother and with better graphics.
• 📸 Photo/video processing —applications like Adobe Lightroom or Kinemaster projects are rendered faster.
• 🔍 Multitasking —switching between dozens of tabs in Chrome or Instagram occurs without rebooting.

However, you should not expect miracles: if your smartphone is equipped with a weak 64-bit processor (for example, Snapdragon 425), it will not become faster than the flagship just because of the bit capacity. The architecture provides potential for performance, but it still needs to be implemented at the hardware level and software optimization.

Is it possible to update 32-bit Android to 64-bit

Unfortunately hardware bit depth is not changed by software. If your processor is 32-bit, no amount of upgrades will make it 64-bit. However, there are several nuances:

1. 64-bit processor with 32-bit firmware - some devices (for example, Xiaomi Redmi 2 or Lenovo A6000) had 64-bit chips, but were supplied with 32-bit data-i="214">. In this case, you can find unofficial 64-bit firmware (for example, on the forum Android. In this case, you can find unofficial 64-bit firmware (for example, on the forum XDA-Developers) and reflash the device.

   ⚠️ Attention: Unofficial firmware may contain errors, void the warranty and lead to a "brick" (breakdown) of the device. Before flashing the firmware, make a backup copy of your data and make sure that the model is accurately supported.

2. Emulation of 64-bit applications — on some devices (for example, with processors Intel Atom), you can enable 64-bit code emulation, but this greatly reduces performance and is not supported by most ARM chips.
3. Replacement of the processor - theoretically possible, but in practice impossible for smartphones due to the integration of the chip into the motherboard.

If your device is initially 32-bit (for example, Samsung Galaxy S2 or HTC One M7), the only way out is buying a new smartphone. Most models released after 2015 support 64 bits.

Which smartphones are still produced with 32-bit architecture

Since 2020, almost all new smartphones are equipped with 64-bit processors. However 32-bit devices are still found in the following categories:

• 📱 Budget phones for emerging markets - some models on Spreadtrum or MediaTek (for example, Nokia 105 4G or itel A23) still use 32-bit chips to reduce costs.
• 📞 Feature phones with Android Go - devices like Nokia 8000 4G or Alcatel 10.5 can run on 32-bit processors due to minimum performance requirements.
• 🔄 Outdated models on the secondary market -smartphones before 2014–2015 (for example Samsung Galaxy S4, LG G2) almost always 32-bit.

If you buy a used smartphone or a budget new product, be sure to check its bit depth. Even if the device looks modern, it may be limited to 32-bit architecture.

Examples of current (as of 2026) 32-bit devices:

• 📱 Nokia C01 Plus - state employee for Unisoc SC9832E (32-bit).
• 📱 itel A48 - phone for Africa and Asia on Spreadtrum SC7731E.
• 📱 Micromax In 1b - Indian smartphone on MediaTek Helio G35 (although the chip is 64-bit, the firmware can be 32-bit).

⚠️ Attention: Some Chinese brands (for example, Doogee or Ulefone) can sell devices with 64-bit processors but 32-bit firmware under the guise of “optimization for the market.” Always check the bit depth before purchasing.

FAQ: Frequently asked questions about 32-bit and 64-bit Android

Can I install a 64-bit application on a 32-bit smartphone?

No, this is impossible. A 32-bit processor cannot physically execute 64-bit code. The only way out is to find a 32-bit version of the application (if it exists) or update the device.

Why does my 64-bit device show that it is 32-bit?

Most likely, your smartphone has 32-bit firmware, although the processor supports 64 bits. This is typical for some budget models. The solution is to flash the device to a 64-bit version of Android (if it exists for your model).

Will a 32-bit smartphone run slower if you install 32-bit versions of applications on it?

No, 32-bit applications themselves do not slow down the device. However, they will not be able to take advantage of the 64-bit architecture (for example, more memory or optimized instructions), so in some cases the performance will be lower than their 64-bit counterparts.

Is it possible to emulate 64-bit games on 32-bit Android?

Technically possible using emulators like ExaGear (for ARM) or QEMU, but this is extremely ineffective: games will slow down, and many will not start at all. It is better to update the device.

Which processors are exactly 64-bit?

All chips based on the architecture ARMv8 and newer, as well as x86_64 (for example, Intel or AMD for PC). Among mobile processors these are:

• 📱 Qualcomm Snapdragon 400/600/700/800 series (starting from Snapdragon 410).
• 📱 MediaTek Helio (all models except the earliest ones, for example, MT6582).
• 📱 Samsung Exynos 7xxx/8xxx/9xxx series.
• 📱 Huawei Kirin 6xx/7xx/8xx/9xx.
