Covremennyy mobilnyy rynok diktuet svoi usloviya: prilozheniya stanovyatsya tyazhelee, igry trebuyut bolshe resursov, a operatsionnye sistemy obrastayut novymi funktsiyami. In these conditions 32-bit architecture is gradually becoming a thing of the past, giving way to more productive solutions. Users often wonder how to switch to a 64-bit Android system in order to unlock the full potential of their device and ensure compatibility with new software.
Switching to a new bit depth is not just changing a checkbox in the settings. Eto fundamentalnoe izmenenie sposoba vzaimodeystviya protsessora s operativnoy pamyatyu i programmnym obespecheniem. If your device can handle 64 bits of data per clock, it can address significantly more RAM and perform complex calculations faster. Odnako, prezhde chem nachinat kakie-libo deystviya, neobkhodimo chetko ponimat tekushchee sostoyanie vashego gadzheta.
Mnogie vladeltsy smartfonov oshibochno polagayut, chto obnovlenie proshivki avtomaticheski menyaet razryadnost yadra. Na samom dele, vse zavisit ot zheleznoy nachinki ustroystva i politiki proizvoditelya. V etoy state my detalno razberem, kak proverit tekushchuyu arkhitekturu, kakie sushchestvuyut ogranicheniya i mozhno li prinuditelno aktivirovat 64-bitnyy rezhim na vashem apparate.

Pervym i samym kritichnym shagom yavlyaetsya diagnostika apparatnoy platformy. Perekhod na 64-bitnuyu sistemu nevozmozhen, esli tsentralnyy protsessor fizicheski ne podderzhivaet etu tekhnologiyu. Cushchestvuyut utility, kotorye pozvolyayut poluchit ischerpyvayushchuyu informatsiyu o chipsete bez neobkhodimosti razbirat smartfon ili podklyuchat ego k kompyuteru.
Ckachayte iz Google Play Market prilozhenie CPU-Z ili AIDA64. After starting the app, go to the System or SoCtab. Pay attention to the line Kernel Architecture or Instruction Sets. Esli vy vidite znacheniya arm64-v8a ili AArch64, znachit, vashe ustroystvo uzhe rabotaet v 64-bitnom rezhime ili imeet takuyu vozmozhnost. In the case of display armeabi-v7a, the processor is 32-bit, and this cannot be changed programmatically.
You can also use the built-in debugging tools if developer rights are enabled on the device. Launch the terminal or connect your smartphone to the PC via ADB and enter the command to get a list of supported instructions. This will give the most accurate answer about the capabilities of hardware.
Hardware limitations and compatibility
It is important to understand the difference between supporting 64-bit applications and running the entire system in 64-bit mode. Mnogie sovremennye protsessory, takie kak serii Snapdragon 700 ili MediaTek Dimensity, yavlyayutsya gibridnymi. Oni mogut zapuskat 64-bitnyy kod, no sama operatsionnaya sistema mozhet ostavatsya 32-bitnoy radi ekonomii pamyati ili sovmestimosti so starym softom.
Proizvoditeli smartfonov chasto prinimayut reshenie ostavit 32-bitnuyu obolochku dazhe na moshchnom zheleze. This is done to ensure that older applications work more stable, since 64-bit versions of apps take up more space in RAM. If you decide to change the firmware to custom, make sure that the kernel (Kernel) is built specifically for the 64-bit architecture.
โ ๏ธ Attention: Trying to install a 64-bit kernel on a device with a 32-bit bootloader will cause the smartphone to stop booting. Vsegda proveryayte spetsifikatsii chipseta na ofitsialnom sayte proizvoditelya pered eksperimentom.

Official method: firmware update
The safest and recommended way to switch to a 64-bit system is to wait or install an official update from the manufacturer. The development company's engineers test the assembly, ensuring the stability of all drivers and system services. In most cases, the transition occurs automatically when you update to a new version Android.
Check for updates in your device's settings menu. Go to section Settings โ System โ System update. If a new OS version is available, download and install it. Often, along with a major update (for example, from Android 12 to Android 13), the bit capacity of system libraries also changes.
โ๏ธ Check before updating
Inogda proizvoditeli vypuskayut obnovleniya vyborochno dlya raznykh regionov. Esli v vashem regione apdeyt eshche ne prishel, mozhno vospolzovatsya firmennymi utilitami dlya PK, takimi kak Samsung Odin, Xiaomi Mi Flash ili Sony Xperia Companion. Oni pozvolyayut vruchnuyu skachat polnyy obraz proshivki i ustanovit ego, minuya ochered OTA-obnovleniy.
Pered proshivkoy obyazatelno sdelayte polnuyu rezervnuyu kopiyu kontaktov i fotografiy na oblachnyy server ili kompyuter. The update process may lead to a complete reset.
Using custom firmware (Custom ROM)
If the manufacturer has stopped supporting your device and does not plan to release 64-bit updates, the only option is to install custom firmware. The developer community XDA Developers often creates builds based on LineageOS, Pixel Experience or ArrowOSthat are completely translated to the architecture arm64-v8a.
To install such a system, you will need to unlock the bootloader (Bootloader). This procedure differs for different brands: you need to wait 168 hours, you need to receive a code on the website, and this opportunity is often closed. After unlocking, you need to install a custom recovery, for example Xiaomi you have to wait 168 hours Motorola โ receive the code on the site, and Huawei this opportunity is often closed. After unlocking, you need to install a custom recovery, for example, TWRP.
The installation process is as follows:
- ๐ฅ Download the zip archive with 64-bit firmware and package Google Apps (if not included in the ROM).
- ๐ Reboot your smartphone into Recovery mode by holding the button combination
Volume Up + Power. - ๐๏ธ Perform a complete data reset (Wipe Data/Factory Reset) to clear partitions of the old system.
- โก Install downloaded archives through the Install menu in recovery.
โ ๏ธ Attention: Installing custom firmware will void the warranty on the device. Wrong actions can turn a smartphone into a โbrickโ that requires restoration through a service center.
What is Project Treble?
Project Treble is an architectural reform of Android, introduced in version 8.0. It separates the OS framework and the vendor's hardware implementation, which greatly simplifies the creation and installation of custom firmware on different devices.
Manual application conversion
Even if the system runs in 64-bit mode, some older applications can function in compatibility mode using 32-bit libraries. This is not critical to your work, but may slightly reduce performance in heavy tasks. It is not possible for the user to completely convert all applications to 64 bits, since this depends on the software developers.
However, you can check which applications on your device are 64-bit. In the developer settings there is an item Run 64-bit applications (if available) that forcibly tries to launch the software in native mode. There are also tools like LibCheckerthat scan installed APKs and show their architecture.
If you are a developer or an advanced user, you can independently rebuild open source software for 64-bit architecture using the environment development Android Studio and setting the parameter ABI equal arm64-v8a. This option is closed for ordinary users.
Problems and possible errors after the transition
The transition to a new architecture does not always go smoothly. The main problem is the incompatibility of old software. Applications that have not been updated for several years may simply not start or crash at startup, since they do not contain 64-bit libraries in their package.
Also, users often encounter increased RAM consumption. 64-bit pointers take up more space than 32-bit pointers. On devices with 3-4GB of RAM, this may result in apps being booted out of the background more aggressively. In this case, it is recommended to increase the size of the swap file (ZRAM) in the kernel settings.
The main problem of the transition is the loss of compatibility with very old software, which is no longer supported by developers and does not have a 64-bit version.
There are also errors in the operation of drivers, especially if you are using a custom kernel. The camera, Bluetooth, or NFC module may not work correctly. In such cases, you need to look for updated versions of drivers or roll back to the previous stable build.
โ ๏ธ Attention: Settings interfaces and menu item names may differ depending on the Android version and the manufacturer's shell (MIUI, OneUI, ColorOS). Always check the latest documentation for your specific model before making changes to system files.
Frequently asked questions (FAQ)
Is it possible to switch to 64 bits without flashing the phone?
No, the bitness of the operating system is hardwired into the kernel and system libraries. This can only be changed by installing a new version of the software (OTA update or custom firmware). There is no such option at the user settings level.
Will the phone work faster on a 64-bit system?
In theory, yes, especially in tasks that require large calculations and working with memory of more than 4 GB. However, in practice, the performance gain may not be noticeable in everyday tasks, and sometimes there is even a slight decrease in speed due to the increased code size.
What should you do if some applications are missing after the update?
Most likely, these applications were purely 32-bit and are incompatible with your new pure 64-bit system (if the manufacturer has removed 32-bit support). Try finding their updated versions in the app store or use alternatives.
How do I know if my processor supports 64 bits?
Use CPU-Z or AIDA64 apps. Look at the "System" or "SoC" section. If the line "Instruction Sets" or "Kernel Architecture" mentions ARMv8 or AArch64, then there is support. Unless ARMv7 is a 32-bit processor.
Does a 64-bit system take up more space?
Yes, the system partition and installed applications take up about 10-15% more space due to the increased size of executable files and libraries. Take this into account if your smartphone has a small amount of built-in memory.
