Installing the APK file: step-by-step guide

If you downloaded the application from the RNKB website or from another source, you need to install it correctly. On modern versions of Android, this process requires additional permissions.

Make sure that the file has the extension .apk (not .zip or .exe)

Check the file size (the original RNKB APK weighs 50-70 MB)

Enable the "Install from unknown" mode sources"

Disable VPN (some banking applications block installation when VPN is active)

-->

Step 1. Allow installation from unknown sources

By default, Android blocks installation of applications outside Google Play. To unlock this feature:

  1. Open Settings → Applications.
  2. Tap on the three dots in the upper right corner and select Special access.
  3. Find item Installing unknown applications.
  4. Select the browser or file manager through which you will install the APK (for example, Chrome or Files).
  5. Activate the switch Allow installation from this source.

Step 2. Checking the file before installation

Before starting the installation, it is recommended to check the APK for viruses. To do this:

  • 🛡️ Upload the file to the service VirusTotal.
  • 🔍 Make sure that the number of detections is equal 0/60+ (zero threats out of 60+ antiviruses).
  • 📌 Check the hash of the file with the data on the RNKB website (if published).

Step 3. Direct installation

When preparation is complete:

  1. Open the file rnkb_[version].apk through the file manager.
  2. Click "Install" and confirm permissions (access to contacts, SMS, storage - this is normal for a banking application).
  3. Wait for the process to complete (may take up to 1-2 minutes).
  4. After installation, launch the application and perform the initial setup (linking a card, creating PIN code).
⚠️ Attention: If after installation the application does not start or displays the error "The application is not installed", check:
  • Compatibility of the APK version with your Android model (for example, APK for Android 12 may not work on Android 8).
  • Availability of free space on the device (minimum 200 MB required).
  • No duplicate installations (uninstall previous versions of RNKB).

Alternative sources: risks and precautions

If official channels are unavailable (for example, due to blocking or regional restrictions), users sometimes resort to third-party APK sources. However, this method is associated with high risks.

Popular (but unsafe) sites:

  • 📦 APKPure - contains many banking applications, but there is no guarantee of the originality of the files.
  • 📦 APKMirror —more reliable, but RNKB may not be there.
  • 📦 Telegram channels and forums are extremely risky due to the spread of fake versions.

How to minimize risks?

If you still decide to download an APK from a third-party resource, follow these rules:

  1. Check the digital signature: the original RNKB APK must have the signature of the publisher AO "RNKB Bank" (can be checked through the app APK Analyzer).
  2. Compare hash sums: ask the bank support for the checksum (MD5/SHA-1) of the current version.
  3. Use a sandbox: scan the file in the virtual machine before installation (for example, Genymotion).
  4. Roll back if suspicious: If an application requests unusual permissions (for example, access to geolocation in the background), remove it immediately.
APK source Risk level Advantages Disadvantages
Official website of RNKB ✅ Minimum Guarantee of originality, bank support Requires manual installations
AppGallery (Huawei) ✅ Low Automatic update, Huawei check Limited functionality, not on all devices
APKPure/APKMirror ⚠️ Medium Available to all regions Risk of fake files, no guarantee of relevance
