On my iPhone, long pressing the spacebar means that moving my finger around moves the cursor around as if I was operating a touchpad.
On my Android phone (running gboard), long pressing the spacebar means that moving my finger left and right scrolls the cursor left and right, but it doesn't operate like a touchpad (the cursor doesn't move smoothly, nor does it move up or down).

Is that not the same for you?
