iPhone 15 Pro Max camera flicker

Hi all,

Recently I’ve noticed that my camera flickers on certain objects, mostly on things that are bright or with an electronic display.

Ive tried my partner’s IPhone 15 Pro on the exact same objects and there is no flicker.

Turning down the exposure to zero helped (I originally set default to 0.7), however my partner’s phone is also on exposure 0.7 and has no flicker.

Does this sound like a fault I have to take to repair? Many thanks in advance
