Why do I have bad signal with an iFixit Lightning Connector

Hi!

I went through iFixit to avoid having the problem that was reported with using non-genuine parts or knockoffs through amazon of having weak or no cell signal with the antenna.

After installing the iFixit kit, I'm having the issue that I thought buying iFixit's more expensive part wouldn't cause. In places I used to get moderate 4G signal I'm down to 3G and in places where I used to get weak signal I have no signal at all. I can still get 4G in some places but it's rare now.

Is there something that I could have botched up in the phone or do I just need to return and get a new part from iFixit.

Thank you,

Denton
