There's seems like two contradictory paragraphs - first you saying that it doesn't using PWM - "A positive aspect is that Huawei doesn't use PWM to control the brightness" and then you saying it flickers on "The display backlight flickers at 178800 Hz (Likely utilizing PWM) ."
Please clarify what it means... Is it pwm free or not? (Really, Looking for review of papper mate version but sadly there's no reviews yet).
