bazuibishang, I see that it's your first post here. Some additional info in your query would be useful, like, what's the make of your phone; its model; whether you ended up having any kind of accident with it at any point, etc. What's a card screen btw?

Actually i didn’t really understand your question. Could you please elaborate your question and please indicate your phone brand as well as its unit type.. Thanks
