ARM64 vs ARM32 APK — Which NetMirror Version Should You Download?

When you visit the NetMirror download page, you will see three APK options: Universal, ARM64 (arm64-v8a), and ARM32 (armeabi-v7a). If those terms look like alphabet soup, you are not alone. This guide breaks down everything you need to know about choosing the right APK for your device.

What Is Processor Architecture?

Every Android device has a processor (CPU) that executes the instructions your apps are built from. The two dominant architectures in the Android world are ARM64 and ARM32, which refer to how the processor handles data internally.

ARM32 (armeabi-v7a)

The older 32-bit architecture that powered Android smartphones from roughly 2010 through 2018. A 32-bit processor can address up to 4 GB of RAM and processes data in 32-bit chunks. Common chipsets include Qualcomm Snapdragon 200/400 series, older MediaTek Helio P-series, and Samsung Exynos 7-series.

ARM64 (arm64-v8a)

The modern 64-bit architecture standard since approximately 2017-2018. A 64-bit processor can address vastly more RAM, processes data in larger chunks, and supports modern instruction sets for better performance and security. Every flagship and mid-range phone released in the last six years uses ARM64 — including Qualcomm Snapdragon 600/700/800 series, MediaTek Dimensity, Samsung Exynos 2000 series, and Google Tensor.

How to Check Your Device Architecture

Method 1: Check via Settings. Go to Settings → About Phone and look for "Processor" or "CPU." Snapdragon 600+ series, any Dimensity chip, any Tensor chip, or Exynos 2100+ means ARM64.

Method 2: Use CPU-Z. Install "CPU-Z" from Google Play. Open it and check the "CPU" tab. Under "Architecture" it will say "ARM64" or "ARMv7."

Method 3: Check your Android version. If your device shipped with Android 12 or later, it is almost certainly ARM64. Google required all new devices running Android 12+ to support 64-bit.

Method 4: Check your RAM. Devices with 4 GB+ RAM are overwhelmingly ARM64. Devices with 2 GB or less are more likely ARM32.

When to Use the Universal APK

The Universal APK contains native libraries for both ARM64 and ARM32 architectures. At roughly 80 MB, it is larger than either architecture-specific build, but it eliminates any guesswork. Choose Universal when:

• You are not sure which architecture your device uses
• You plan to share the APK with friends who have different devices
• You tried an architecture-specific build and got an installation error
• Your device uses an uncommon architecture like x86

Common Issues When Downloading the Wrong Version

Installing ARM64 on an ARM32 device: The installation will fail immediately with an "App not installed" error. No data is lost — the Android package manager rejects the incompatible binary. Download the ARM32 or Universal build instead. See our app not installed troubleshooting guide.

Installing ARM32 on an ARM64 device: This actually works because ARM64 processors have backward compatibility with ARM32 code. However, the app runs in 32-bit compatibility mode which is slightly less efficient. Use the ARM64 build for optimal performance.

"Parse error" after downloading: This usually indicates a corrupted download rather than an architecture mismatch. Delete the file and re-download on a stable connection. See our parsing error fix guide.

Our Recommendation

For most users in 2026, the ARM64 build is the right choice. The vast majority of Android devices sold in the last six years are 64-bit. If you have an older device or are not sure, grab the Universal APK.
