# How do I remove dark areas from my mesh?

I am doing this tutorial to model an iPhone. One of the things I try to work on is my ability to judge wether a mesh is ok or not ok. Now I think that these parts are not ok

So ... is there something wrong or not ? I already tried moving vertices but could not make these "dark areas" go.

Also ... at about 10:30 min of the tutorial the "tutor" feels the edge of the iphone should be more "rounded" and repairs that. I thought my edge is ok ?

• You could press Alt+. (coma) to change Pivot Point to Active element, select vertices from the phone back and one which is located correctly as the last one (so it to be active) and scale by Y axis. This would let you skip copying values. – Mr Zak Nov 28 '15 at 15:29
