  2. Go to Security or Privacy (depending on your device model).
  3. Search options Install unknown apps or Unknown sources.
  4. Enable this option for the browser or file manager you used to download the file.

Minimum system requirements: Android 5.0 (Lollipop) or above, at least 50 MB of storage space, and a stable internet connection.
