Microphone not working anymore

Hey there, please find relevant information here, to check if you have an issue with the primary microphone of the Fairphone 2 or not: https://fairphone.zendesk.com/hc/en-us/articles/213161166-My-microphone-does-not-work-properly

Sometimes reassembling the phone helped. There are also some similar problems discussed here:

Microphone not working anymore

A month ago my microphone stopped working at first just sometimes and if I reboot the phone it was working again… Then it stopped working. I’ve got problem of rebooting without doing anything too (it is random)… Has anyone experience that? Can anyone help? (Support is not answering so far and it is not convenient to have a phone without being able to make/receive a call… )
