Lines or screen flicker may occur when taking photos of the Zenfone’s OLED (Organic Light Emitting Display) display with a camera or mobile phone.
This phenomenon results from the OLED display which uses PWM (Pulse-Width Modulation) to dim the brightness.
The PWM happens at a very high rate so it can’t be perceived by the human eyes.
Only when the camera shutter speed is within a certain range can you see lines or screen flicker occur
To minimize the appearance of these on your photos, try the following tips:
(a) Set the Zenfone screen brightness to maximum level.
(b) Adjust the camera shutter speed and ISO.
(c) Change camera flicker settings
