Allow Unknown Source Apps
Because you're installing an app from outside the Google Play Store, Android will ask for your permission. This is a standard safety measure designed to keep your device secure.
Settings Path:
Navigate to Phone Settings > Security > Unknown Sources
Version-Specific Instructions:
- For Android 8.0 and newer: Open Settings > Apps & notifications > Special app access > Install unknown apps
- For Android 7.0 and older: Go to Settings > Security > Unknown Sources
Pro Tip: To keep your phone secure, only enable 'Unknown Sources' while installing this app, then switch it back off immediately after.
