Hello. Take a look at what I've found:
https://support.google.com/pixelphone/thread/380106057/purple-light-haze-from-main-lens-on-close-up-shots-in-dark-btw-i-m-using-pixel-10-device?hl=en
Is there any way to disable that purple light with GrapheneOS, or is there a Google Pixel model that doesn't have it or doesn't have it positioned in that place?
Where it is, what it says in that link happens: “it makes the phone unusable filming with cpl or nd filters without taping the LDAF.”
