Yellowish tint on brand new iPhones!
There are different batches of screens. Some iPhone screens have a yellowish tint (without any colour setting turned on) and some have NORMAL screen where white looks white and not yellow. I have been using iPad and iphone since 2011. I have noticed this on every single model every year. I have gone through replacement exchange until I receive the normal screen device. Apple are useless they always pretend it’s the first time they heard of it and I’ve gone through this with them every year via replacement exchange. It’s a manufacturing issue as far as my research concerns, the bonding under the screen needs to be cured under uv light during curation process, if the requires timing limit is not achieved it leaves a slight yellowish hue on screen, hence majority of the early produced batches have this issue (rushed production) and especially the ones on demo in any Apple Store. The production of later devices 2/3 months after release are majority normal screens. I have this issue every year. Last November after 3 exchanges for my 16pm it was resolved. This year since October for my 17pm i completed 2 exchanges and my 3 exchange any time due now. Apple reject any knowledge of this. I know this issue better than Apple themselves. It’s not acceptable. I answered my own question for any one who has this issue your not going crazy and it’s not just you or your eyes!
