    Answer a few quick questions to evaluate your visit.

    Downloading applications from other sources

    When your device is set to allow downloads from sources other than Google Play, you can download applications directly from other websites by following the relevant download instructions.

    Installing applications of unknown or unreliable origin can damage your device. Download applications only from reliable sources. Contact the application provider if you have any questions or concerns.

    If you are using a device with multiple users, only the owner, that is, the primary user, can allow downloads from sources other than Google Play. Changes made by the owner affect all other users.

    To enable or disable the downloading of applications from other sources

    1. Find and tap Settings > Apps & notifications.
    2. Tap Advanced > Special app access > Install unknown apps.
    3. Tap the application you want to allow the installing of application from other sources, then tap the Allow from this source slider to enable or disable.
