FP3 HW extension port?

[BertG]

@JeroenH

Where? For me, it is pretty much spot on

Unfortunately not everyone is sharing your experience, as unvoluntary touching the sensor is already mentioned in this forum:

Fingerprint sensor sensing too fast

Sometimes while gripping my locked phone, I’ll accidentally lightly touch the fingerprint sensor and it will take too many failed readings and require a screen code. It takes the readings at an inhumane rate, like 6 or more per second. Is there a way to set the time between readings to prevent this, like to 0.5 s?

@JeroenH

I would not want to trade it for an extension port.

Others might be willing:

FP3 fingerprint

Is it possible to remove the fingerprint sensor or get a backcover that blocks it? I have owned every Fairphone and i really like the idea, i also liked that it didn’t have a fingerprint reader, for me not having a fingerprint reader is a feature. I am considering PINEPHONE and the Librem 5 instead of the FP3 but for now i’m happy with my FP2.

I know it will be larger, but this option is realistic and can be achieved now.
Imho I dont’t think that modifying the FP3 fingerprint sensor or anything else to get an hardware extension board will ever happen, cause the number of users is damn small,

You might be right of course, though it escapes me, why an extension board to plug into the USB port would be more realistic (well, maybe it’s much easier to achieve) or attracting more people than som ingenious stuff like this one for FP2. And the ones realising the extension board would most likely be the same ones realising an “internal” solution. I have no idea how many PCB extension were made, but the thread says, they were sold out.

Making an extension-PCB with capacitive buttons for FP2

Here you can see the result of printing the edited case files [image] The pcb is just fitting perctly into my designe [image] [image] But what do you think?

Here’s one of the pictures:

@JeroenH
This and the other pictures in the linked thread might illustrate, what I had in mind with relocating the fingerprint sensor. It would take a new backcover of course, but I love this neat design.

Of course it was just an idea of mine, and I am far far away from being a technician, so this might be absolutely out of reach. But seeing picture 3 of Step 9 from the iFixIT teardown of the FP3 the fingerprint sensor at least includes a tiny PCB attached to it, though I have no clue, if the contacts used for this sensor would be of any use for an extension port.
