I'm not sure if this related. I was going to post this to feedback as to help the fairphone developers to not make this mistake in the next batch, though I did not find a feedback corner, so I put it here:
When I listen to my music on headphones, at maximum volume, after the warning, the sound I get to hear is so incredibly silent! This would be a reason for me NOT to buy a fairphone again. That's how low the actual volume is I get to hear. The maximum volume after warning is not even near the maximum volume I would ever listen to , let be close to even normal level. I mean, I can sometimes not hear certain instruments and nuances in the music well.
This is the only thing, but a really enormously big thing that I am really not happy about about my fairphone.
