I would like a phone that has a removable battery, user replaceable screen, and expandable storage. I think Framework would do well to add one or two of their modular slots on the phone since phones already have USB-C support. I would also love to see a phone keyboard similar to the PinePhone keyboard case but using USB-C instead of I2C. Such a case could also incorporate a USB-C dock, providing more Framework module slots or at least additional USB ports, video outputs, an extended capacity battery (using USB-PD to charge itself as well as the phone), and of course also being a tiny keyboard clamshell that fits in your pocket. It could also be nice if the phone could easily detach from said case for taking calls, as the PinePhone keyboard replaces the back cover and does not separate easily when needed.
