Parts needed: ear phone connector and microphone

[Alex.A]

@qesad

I have troubles with the connection for the headphones.

So troubles with the jack plug? Top module.

@qesad

Also the microphones seem to be defective.

Both?
Main microphone: bottom module
Secondary microphone: top module

@qesad

Which parts do I need then and can I still by them in the shop?

So I guess you will need the top and bottom module.
Both can be bought from the shop (the top module only with the 2MP camera though, not the newer one):

Fairphone 2 Bottom-Module | Fairphone

But be sure the parts you have really are defective and it’s not a contact or software problem!

@qesad

By the way, are core modules for FP2 still available in the shop?

No. They never were. At some point, vireo.de sold some, but they don’t anymore.

EDIT:
For reference, you can find a list of the components in each module here:
