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.


Lines appear on camera preview screen or photos.
