(Sorry for the quality I took the video from my old N73 phone)
If you can't see the video when I slide the keyboard the screen have some kind Water drop effect in the middle
What cause it ? should I be worried ?

First, give link to video; this link is to an image/picture.
Second, something is wrong with slider mechanism. A part of the mechanism connecting two parts of the phone is pressing on the screen from behind, when it shouldn't.
Best wishes.

oh thanks , I tried to loosen the two screws a little it helped but it I found the gab between the screen and keyboard is higher , It wasn't like that before what should I do ?
By the way if you click in the image will send you to the video , because youtube was giving me a hard time , I used this host and included a thumbnail so the user's don't think I'm giving them a link in a malicious site or something

The screen is being pressed from the back, if you paid somebody to fix it ask him to recheck and show them what they did wrong. I think the screen can get damaged if you keep it like that.
