1. Open Settings > Security.
2. Locate the setting Unknown Sources and turn it off.

For earlier versions of Android:

1. Open Settings.
2. Tap Apps & notifications > Advanced > Special app access > Install unknown apps.
3. Tap the name of the app you want to stop asking you to install unknown apps.
4. Turn off Allow from this source.
