Hello,
according to the check app my primary and secondary mic stopped working. I am considering to give it a last chance and invest into a new button and top module.
I am just not sure if there is anything else wrong with my Fairphone.
If I oder spare parts, is there any chance to just return them to Fairphone and get a refund?
If you did not cause any defect yourself and if the FP2 and its parts are still within warranty (two years, except for the battery: 1 year), then you can qualify for a warranty replacement of the non-working modules. Top, camera and bottom modules are usually replaced without the need to send the defect ones back to Amsterdam. However, you will need to go through various procedures to rule out any other issue causing the malfunction. See https://support.fairphone.com/hc/en-us/articles/115001041206.
Well, then I’d still try everything the Troubleshooting Tool suggests. Additionally, you can contact a Fairphone Angel if any is located near you. That might allow you to cross test your modules and perhaps someone else’s.
