hi there when i want to call someone using phone book, i want to call the default number of the contact just by swiping that contact in the phone book. But my galaxy s performs differently on various occasions. sometimes it does dial just by swiping the contact. sometimes it opens up the contact and shows me the various numbers of that particular contact and then i have to swipe the default number. sometimes it further opens up a small white screen showing different numbers of that contact and then i have to swipe the number. can anyone please explain why these things happen and how to avoid them?
