This is a bit of a long shot but this community is probably the most likely to be of any actual help. The Fairphone 4 is a really nice phone from a repairability perspective but it lacks several features I still consider essential in a modern phone (namely a headphone jack and full oled screen without a camera cutout) so I’m curious how modifiable the Fairphone 4 can be?
Could we obtain another screen from elsewhere, move or completely remove the front facing camera and integrate a headphone jack into a Fairphone 4? I’m assuming the screen just uses a MIPI DSI connection but I’m worried there could be software that expects a specific Fairphone screen so changing it out probably wouldn’t work even if we could somehow get the connector to line up. As for the headphone jack I wish there were a mostly sane way of adding that internally without just making an internal USB C dongle and printing a larger enclosure but at that point it could just be an external dongle thereby somewhat defeating the point.
Somewhat offtopic but it’d be absolutely amazing if there were DIY options for phones like there are DIY options for assembling a computer. Where we could pick out whichever easily available and off the shelf parts we wanted and then just assembling the phone ourselves. Unfortunately the limited space pretty much requires some proprietary components and connector types so that dream will probably never happen. Sure there seem to be a few standards like MIPI DSI but space, cable length, and possibly software assumptions make that standard pretty much useless from a DIY perspective and considering that Fairphone’s parts aren’t backward compatible this probably won’t change anytime soon either.
