=== Assistant: Thank you for describing that clearly. ===
Thank you for describing that clearly. I want to be very careful here and keep this grounded in physics and how phones/screens actually behave — without reinforcing an explanation that would mislead you.

What you just described:

: 

still does not match a motion detector or anything that is sensing you. There is a much simpler, mechanical explanation that fits all of your observations so far.

==== When you take a step forward while holding the phone, three things change at once, even if you don’t consciously notice them: ====
# The phone tilts slightly (pitch/roll)
# Your viewing angle changes relative to the LCD
# The UI content subtly reflows / redraws (even without scrolling)

Because the artifact lives in the display’s post-render processing layer, not in the pixels themselves:
* It is anchored to display processing tiles
* Not to the glass
* Not to the content
* Not to you

So when the phone angle or orientation changes even a little, the controller’s tone-mapping regions get recalculated, and the artifact appears to “slide” briefly before settling again.

That motion feels responsive, but it’s not tracking — it’s re-projection.

==== Your brain is very good at detecting contingency: ====
* “I move → something moves”
* That feels interactive

But in this case:
* The phone is moving
* The display pipeline is recalculating
* The artifact shifts as a side effect

It’s the same reason:
* glare spots move when you tilt a screen
* contrast patches shift on cheap LCDs
* ghosting appears/disappears when walking

None of those involve sensing you.

==== Please try this exactly — it cleanly separates “detector” from “display artifact”: ====

===== 1. Sit the phone down on a table, perfectly still =====
# Keep the screen on
# You take a step forward/back while the phone does not move

Result meanings:
* If the dots do not move → display artifact confirmed
* If they still move → then we reassess

A motion detector would respond to you moving.
A display artifact only responds to the phone moving.

==== Hold the phone very firmly with both hands, elbows braced, and take a step. ====
* If the movement largely disappears → again confirms it’s phone orientation/angle
* If it were “detecting motion,” bracing wouldn’t matter

==== I am not saying: ====
* “you’re imagining it”
* “it’s in your head”
* “nothing is happening”

Something is happening — just **
