Before You Install — Enable Unknown Sources
Since the 81550 app is distributed as an APK outside of the Google Play Store, you'll need to enable the Unknown Sources or Install Unknown Apps on your Android device first.
These steps vary slightly depending on your Android brand and version:
- Android 8.0 and above: Go to Settings → Apps → File Browser or File Manager → Allow from this source.
- Android 7.x and below: Go to Settings → Security → Enable “Unknown Sources”.
Minimum system requirements: Android 5.0 (Lollipop) or later, at least 30MB of free storage, and a stable internet connection.
