Bottom (main) mic not working after earphone jack replacement

As stated in the title the bottom mic is not working after I replaced the whole bottom connector unit with a 3rd party one. It appears to me as if the mic is not in line with the whole in the case. I cannot aline it properly as its position is pretty much fixed by the cable it is attached to. And idea what I could do? Are there faulty connector units (construction-wise) on the market? Also a little rubber seal (I guess) got lost at the replacement. Not sure if that was part of the mic or earphone jack.

Update (10/13/2017)

Thanks for the answers. I fixed the problem now:

I bought a used back-case on ebay an took it apart. As suspected, between the mic and the hole in the case there is a small plastic piece which guides the sound from the hole in case to the mic which is attached to the dock connector unit. I do not mean the mesh part.

When I removed the old unit this plastic piece stuck to the unit and I accidently threw it away. In the video you posted the plastic thing seems to remain in the case.

So when anybody has a similar problem. You might wanna check the old unit if there is still the plastic piece stuck to the mic part.

the rubber part is from the mic as it holds it in place on the chassis

Thanks for the answer. I do not mean the piece with the 2 screws. This I installed again. There was a smaller flexible rubber seal which might be needed to „guide“ the voice the mic.

Is it not working completely or can people barely hear you talking?

Small parts, such as flexes, cameras etc. have a reputation for low quality. It is entirely possible that you have a defective or low-quality replacement flex. Ideally, you need either a known-good component or have access to another working device to help isolate the problem.

I wold also go through this repair guide, if you haven't already done so, to insure everything looks good.
