For accessibility reasons I want to create a dead spot in the lower right corner of an Android Pie phone (Xiaomi Mi A3) so that touching does not do anything.
The phone comes with a new 2-button navigation button and a pill-shaped home button. I've tried to customize the navigation bar with the "settings put secure sysui_nav_bar" trick, and I've been able to get the buttons I want, but I can not create a dead spot on the right side (or any other location) left and left handles will be treated as part of the next button, even if you insert a "space" element there. The best I've come up with is
adb shell settings put secure sysui_nav_bar "back;space,home,space,space,space;recent,contextual"
This creates a left-aligned navigation bar, with the context button on the right as the dead center, unless the context icon is actually displayed.
What I need is an element that does nothing, or maybe one that uses virtually no app, so it effectively does nothing. Is there something like that?
Thank you very much
