A LiDAR scanner measures the room directly, so the product appears on the floor the moment the camera opens. Devices without LiDAR watch how the image shifts as the phone moves to work out where the floor is — that is a property of camera-based AR on every platform, not a vendor limitation.
Guided placement typically takes 5–15 seconds in good light on a textured floor. Dim rooms, plain or glossy floors and standing still make it slower. After placement both behave identically.
Why it matters
Knowing this stops teams from misreading normal AR behaviour as a bug — and helps write honest on-page coaching for shoppers.
