Got the pinephone, works great for what it is.
Got the keyboard, remember to avoid using the phone usb with the keyboard mounted.
1 year later, battery unit in keyboard still works great, but keyboard died after auto-repeating a ton of characters while writing a text message.
Felt like a cable failure to me, similar to how a laptop keyboard goes out sometimes.
Now I need to pry open the keyboard and try to figure out why pine64 does not sell replacement cables for the keyboard's internal pogo pin interface to the phone.
The hinge still works good, but the cable was routed through there, and would obviously flex a little.
I do not think it is a ribbon cable, at least.
Just really thin gauge wires in a sheath.
