Hi, Samsung apps do not update over wifi. A popup comes "Network unavailable". They used to earlier, however once I started using my mobile data connection, they seem to only update over the mobile connection and do not want to update over wifi ??!!!! I don't want to update Asphalt over mobile data but over wifi. I have tried switching the phone off/on but it still does not work. I am using apndroid to disable/enable the mobile connection.
