Main differences:

How to check CPU type: Install "CPU-Z" from the Play Store, open the app, go to the "SoC" tab, and check "Architecture". If it shows ARM64 or AArch64, your device supports the ARM64 APK.

By default Android only allows installs from the Google Play Store. Because the a880 APK is installed outside Play Store, you need to allow "Install from Unknown Sources" (or per-app install permission).

This is a standard, safe procedure for installing an APK directly. Millions of users worldwide use the same steps for apps that are not on Play Store.

Security note: Android 8.0+ uses a per-app permission (safer) instead of a global switch on Android 7. After install finishes, you can turn the permission off again for extra security.

Not usually when updating from v4.x.x to v4.8.2. Android upgrades in place and keeps your data and settings.

Uninstall first if:

• Install fails with "App not installed"
• You see persistent bugs or crashes
• You are switching from a modified/unofficial build to the official version
• You are doing a major upgrade (for example v3.x to v4.x) and hit issues

If you must uninstall: Back up important data first (if applicable), then go to Settings → Apps → a880 → Uninstall.

System requirements for a880 APK v4.8.2:

• Android Version: Android 6.0 (Marshmallow) or higher
• Storage Space: At least 100MB free (200MB recommended)
• RAM: At least 2GB (3GB or more recommended for smoother performance)
• Processor: Any ARM, ARM64, x86, or x86_64 processor
• Internet: Needed for download and initial setup (Wi-Fi recommended; Grameenphone/Robi data also works)

Device compatibility: Tested on 15+ brands including Samsung, Xiaomi, OPPO, Vivo, Realme, OnePlus, Asus, and Google Pixel — common phones used in Dhaka and nationwide.

SHA-256 checksum is a cryptographic hash that uniquely identifies a file — like a digital fingerprint.

Why it matters:

• Verify File Integrity: Confirms the download is complete and not corrupted
• Detect Modifications: Even a 1-byte change produces a completely different hash
• Reduce Malware Risk: A mismatched hash means the file may have been altered
• Clear Result: A matching hash means the file matches the official build

How to verify: Download "Hash Droid" from the Play Store, select the APK, and compare the SHA-256 with the official hash a3f5b8c2d1e9f0a7b4c6d2e8f1a3b5c7d9e0f2a4b6c8d0e2f4a6b8c0d2e4f6a8. It must match 100%.
