Samsung Flow is available as a free app for users, with no trial period or subscription required for its basic features.

Samsung Flow primarily requires a stable internet connection for certain features, but it can also function over a local Wi-Fi network for direct device-to-device communication.

Users can contact Samsung support through the Samsung website or app store where they downloaded Samsung Flow, where they can submit feedback or report issues directly.

Since Samsung Flow does not have a subscription model, there is no need to manage or cancel a subscription; users simply need to uninstall the app if they no longer wish to use it.
