Users of the new smartphone have been reporting a purple haze noticeable in photos where the lighting is very bright.
Now one user has received a response from Apple Support after having the issue escalated to engineering.
Our engineering team just gave me this information and we recommend that you angle the camera away from the bright light source when taking pictures.
