@overholt @ymasumac @josh0 I've definitely had laggy old phones where the updates have piled up to the point that the sensor fails to trigger the touch disable quickly enough to prevent accidental ear / cheek touches. Not sure how it works in iOS but for Android at least if touch inputs are ongoing because your face is already mashed on it won't lockout further inputs when the OS catches up to the sensor. The only workaround was to consistently remember to hover the phone near but not touching for a few moments to give it a hot second to catch up.
