Ordering of the issues based on impact

The issues are ordered based on their impact. The categorization of these are the same as on the Fairphone support page. However, the ordering may be relative and of course depends on how you use the phone. If you have an active night life, then low light camera issues might affect you more than others. We as a community have to find the middle ground. So we have to balance the impact based on how people use their phones in general and order it accordingly.

Icon Markdown Description
:red_circle: :red_circle: High impact - I cannot use the phone at all
:orange_circle: :orange_circle: Medium impact - I can only partially use the phone
:green_circle: :green_circle: Low impact - I can use the phone

Camera issues

A separate list is maintained because the camera is one of the most discussed topics and everyone values it differently. It also makes the list of issues more readable when we separate the camera issues.
