Yep. The OLED glass is about 1.6 mm thick, and PCB is 0.8 mm
I have to check what components i need on the board. atm i expect about 2mm increase in thickness.

They are with scotch tape/wire still...
I made a custom pcb that has matching pads for the phone pogo-pins (pins on the phone side have the springythingy)
Pic of first version of board...

Good point. I did not try (yet!) to prod the pins on the phone side, as I thought they were fixed, but they are indeed pogo-pins! Now the price of the Jolla is getting justified

Update.

SW
I have now achieved writing a service/daemon which is on D-Bus systemBus, and managed to configure policies so that it can own a name and be communicated with. Also configured systemd to start it at boot.

Now i can access the rear I2C bus and V33 output through D-Bus from normal application without starting it as root.

HW
I think i will do board as FPC - then i can keep height in minimum.
Thickess increase should be ~1.5mm, which is thickness of OLED glass.

Help...Hjälp...Apua...

Can someone dig/hack/design/suggest me a font to show big time on the screen? There is space of 128x48 pixels.
Numbers 0..9 and : needed. Preferably fixed width of ~28 pixels, 16 px for : .

Height max 48. (Width adjusted to what looks nice)

something like this:

23:56
28+28+16+28+28

in 32-bit hex words arranged to table, right aligned (leftmost 4 msb bits wasted.) one word/pixel row of character.

There is 128x16 free space below, but i think there could be notification icons tjsp,

I do not know what font is used on N9, but that looks good.

I can suggest using fixed-width fonts. Otherwise arranging spaces between characters might be problematic.

For example with fixed-width courier new font:
