Image texture is not mapping correctly I unwrapped part of my mesh (front of an iphone screen) and added the image texture. 

Strange things are happening but this image texture is not mapping correctly. What is wrong and how to solve this problem ?
There are few issues in the UV Mapping.



To fix theme, select the faces with Screen Material in the Material Panel,



then UV map "Project from View (Bounds)" (U -> Project from View).

If you disable the Subsurf modifier, it works.
To fix the Subsurf issue, add an edge loop near the external edges of the screen.
