weak gps and wifi signal

hello, i noticed that after the reapir man fixed my Iphone 4 "Power" button, the gps and wifi very weak !

the gps once in a while finds signal and than tells me again "no GPS signal".

I opened my Iphone 4 back cover and discovered that the GPS screw (http://guide-images.ifixit.net/igi/ZUVK6... - the one in green circle) is shaky and isn't screwed, he is just shaking.

does he suppose to be shaky? and is it the cause of the weak gps and wifi signal?

thanks and sorry for my english, Eitan.

EDIT: i unscrewed the screw from the red circle from the picture i added before and i saw that he is much bigger than the one that was in the green circle.

does the green screw should be bigger than the red one?

I'd take a look at the excellent guide linked under the photo of the iphone (top right) and measure the screws according to the guide and then put them back correctly. They shouldn't be loose or shaking or contact isn't made with the logicboard ground (a gold half circle imprinted on the board) which is maybe why you have poor/lost signal.

I fixed the problem.

I found out that the repair man broke the screw and left the broken part inside the logic board there was no contact between the wifi/GPS part and the antenna. So I took some copper from a cable I found at home and I put it in the place where there was suppose to be the screw and it fixes the weak signal :)

Thanks a lot !!
