Microphone repair went perfectly
There's a lot of posts about how bad their support is, so after having used them myself I feel obligated to say I have no idea what y'all are talking about, fairphone's support is amazing, one of the best customer support experiences I've ever had.
Basically my main microphone wasn't working, people couldn't hear me on calls and voice recordings also weren't working (I bought a transparent FP5 in late 2023 directly from their website and the microphone worked fine for the first 1.5 years). I used the troubleshooter on their website to identify the problem but was hesitating getting it fixed because of all the negative posts about dealing with fair phone support. Finally I decided a phone not being able to call is like a watch that can't tell time. I was a bit unsure if it was really hardware or maybe software, so I used their online chat during business hours to ask. The live chat person wasn't a technician so they didn't know, they made a support ticket for me. I told them my issue and they always responded quickly (within one business day) and clearly. Once they determined it was hardware, they gave me instructions to send it for repair, and less than two weeks later (including shipping) I got my phone back and the microphone is working fine, all for free covered by warranty (fairphone's voluntary 5-year warranty, for me the 2-year legal warranty already passed).
Of course, I was annoyed I got unlucky that the only part that you can't fix yourself was the one that broke for me. Cause a main reasons I got a fairphone was because you can fix it yourself, so hopefully the microphone will become repairable at home with an ifixit screwdriver in a future model. So then the result of not having a phone for two weeks and worrying about backing up my data correctly to restore it (cause they are required to do a factory reset) was a hassle but that's industry standard, not just fairphone. And I did unfortunately loose data in a couple apps despite trying to be really careful with backups and restoring.
Also in general, I've had iPhones and Android phones before Fairphone, and I'm super happy with the fairphone in all aspects, it is absolutely on par with their flagship phones, I don't know what people are talking about. For all the posts here like "just got my Fairphone, is it normal that it's doing X..." No it's not, their factory output isn't yet perfect, get it fixed!
