Samsung Galaxy phones and tablets comprise processors configured to, “indicate to the first 

end-user application, via an application program interface (API), one or more network access 

conditions based on the applied first differential traffic control policy.” For example, 

applications running on the Galaxy S22 use ConnectivityManager API, which indicates to a first 

end-user application a network access condition based on an applied differential traffic control 

policy.
