If my memory serves me right, someone tried operating the FP2 without camera modules and it worked just fine.
The idea of dummy modules strikes me as a great one, as there are places out there, where photo-phones are not allowed. So being able to replace both camera modules might be a good idea. I just would not expect it to take a top place on the priority list and I am not sure, how big a market such a thing really would serve.
But that’s just my - non techie - user opinion.
You forgot the fingerprint sensor and NFC chip in that list.
GPS, wifi and all other connections can surely not be switched off through hardware. Same goes for NFC and the fingerprint sensor.
Taking out the cameras and microphone should work, but with limitations to other functions of the phone as explained above.
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:
Do you by any chance have a bluetooth headset (microphone & speakers) to test if sound is still transferred to & from that phone when a phone call is made? Is it possible to listen music on the headset?
And, you might know, is this possible with FP2 too?
Sorry, I had to forward this FP3 to the upcoming Hamburg meetup yesterday (currently shaking and biting my fingernails hoping it will arrive there in time). Besides, I haven’t got any bluetooth audio devices, so I cannot test this with the Community Aachen FP2 either.
