default colors while switching views

I tested my apps with regular (non-developer) people, on the road.

One of my apps is darkish-ish (maroon). One thing that people notice is that in between taps, there are these flashes of bright white full screens.

Could you point out where the colors for these "base" screens can be configured?

If they are not configurable at the moment, perhaps this bug can serve to make them explicitly configurable so that the user does not perceive as much the lag involved.

Side note: perhaps the lag can be addressed in the platform?

Start by locating where the iOS app creates or configures the base screens shown during view switches, then reproduce the bright flashes while changing views. Done means the relevant default color behavior is clearly documented or configurable so dark-themed apps do not show unintended white screens.
