Pretty much all VNC apps are just not smart enough to handle the unusual layout, and assume all these special keys are a one key press affair as they would be on a "regular" physical keyboard. Maybe this could be worked around on an Android level somehow. But just a reminder that the Gemini is likely extremely insecure to use anyway, given Planet Computers abandoned any reasonable attempt at keeping up with security patches almost immediately after release like it's some throwaway 50 bucks device. Given they can't even do these utter basics, it seems unlikely any sort of better emulation of keys for "dumb" apps will be done on a system level.
