OK, so I’m writing this from the FP3 with all four small modules not in the device: Top, camera, speaker and Bottom modules are all lying on the tablet here right next to (yet outside of) the FP3. Annoyingly still included: Auto-correction, stubbornly trying (and acting) to read German or Dutch into my typing.
Please note: The FP3 refused to boot with both all four modules and all screws removed. It only booted again once I had screwed the twelve Phillips #00 screws (there will be 13 in the commercially available FP3) back into the outside of the core module.
UPDATE: Please find a little bit more and updated information about this here:
