Question

I mean, how can I check that user’s device is not a tablet (or music player) without dialer?
P.S.: My app uses numeric codes entered in dialer, so I want to check it’s presence.

Answer 1

Seems to be what I’ve needed:

public static String TelephonyChecker (Context context) {
        TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
        if(manager.getPhoneType() == TelephonyManager.PHONE_TYPE_NONE){
            return "Off";
        }else{
            return "On";
        }
    }
