this problem is well documented.
No solution, so far, though.
Apple do supply an App to fix the problem of red eye though.
On my iPhone X every time i take picture with flash in low light condition , people are having red eye !
I've tried with case, no case, different camera settings! still the same issue.
Does anyone have the same problem ?
I've contacted Apple, still no answer. The apple support chat session ended up to : they need a "Senior Advisor regarding this case".
A 1000$ phone which cannot take a simple picture without redeye and so may AI built in to it !
iPhone X Say Hello to the past.
