Wifi reduced after screen replacement

OK, First of all, Replacing the iPhone 4 screen is a royal pain in the a#$. It is seriously my least favorite repair to do. When you replace the screen on the iphone 4, if you get the oils from your skin on anything..... I mean anything.... It will cause wifi signal issues.

To combat this, when I replaced mine, I wore latex gloves, and cleaned every surface I touched with "Windex"(Because it is a powerful degreaser), just keep it off the logic board. I know this sounds pretty crazy, but my wifi signal actually works better now than before I tore it down now. My friend did his, and didn't clean the surfaces his skin came in contact with, and his wifi antenna barely works now.

I don't think you need to replace anything, just go in there and sterilize every surface. I am certain it will work.

Let me know!

Check if in top of the metal panel is a little peace of metal where u get the big screw.

:p

Yeah, there's a long screw that goes right in the top of the device, the is vital to wifi. I didn't fit it properly and it barely worked, after replacing it it worked fine.
