Choosing the Right APK Version

Check if your phone is 32-bit or 64-bit first. Most Android phones made after 2017 are 64-bit. To check:

1. Go to Settings > System
2. Find “Kernel version” or “About phone”
3. Look for “x64” or “aarch64” = 64-bit phone

• Nightly: Latest features but may have bugs

Enable Unknown Sources

Android blocks APK installs by default for security. According to the Department of Homeland Security’s study on mobile device security, mobile devices are exposed to a distinct set of threats that frequently operate outside of enterprise protections.

2. Android will show a warning about unknown sources
3. Tap the “Settings” button in the warning
4. Toggle “Allow from this source” to ON
5. Go back and install the APK

For older Android versions:

2. Find “Unknown Sources” option
3. Check the box to enable
4. Read the warning and tap OK
