Only seeing who is calling me and being able to answer. This could be gotten around, for example, by having the phone ring be morse code for the persons name or having a very simple lcd display on the side of the keyboard.
For that, a small two-colour display can be used like any of these - I mean the display itself and not the whole module.
They have I2C capability, so practically they may also be connected to the same I2C bus like the keyboard is.
...and the rest only need some programming - so when the phone is ringing, the display may contain caller info and also some battery / signal indication can be put there.
Also, if the keyboard can determine if it is in opened / closed state then these information may be not written when opened.
So, such a small display could be a good addition to reach most important data in closed state and it does not need colours or high resolution.
Also an LCD display may be used instead of OLED with similar capability but it is a question of decision if it has to also support colours.
