I just updated my Fairphone 3+ to the latest version of q (IMG-e-0.12-q-2020111084008-dev-FP3).
The sound module is working. But the recordings had a lot of noise, especially with low volume parts or at the end of speech. It sounds as if the recording is being compressed (too much) increasing the noise.
I tried with the recorder app and with the camera app.
What results do you have? Is it only my device or do you have similar results?
