(Using a Sonim XP3plus/XP3900) I'm trying to configure a physical activation key in the Voice Access settings. I'm able to open the menu and chose which button I'd like but it won't save. There are two buttons named 'OK' on the screen (corresponding to the upper-right and upper-left selection buttons on the phone), but selecting either one just remaps/selects that button as the tentative option to be mapped as the Voice Access activation key. Similarly, pressing the middle button on the D-Pad just remaps the Voice Access key selection to that button, but it doesn't save the selection. I am unable to find a Save/Enter/OK button that works to save the setting.
I checked Scrcpy but did not get any additional 'hidden' save options or any additional buttons.
As suggested in a previous post regarding this issue, I also tried using the Voice Access app itself to save the selection but it did not recognize any save/enter/ok type command I was able to think of trying.
Can anyone help?
