Green tint on iPhone 12 iOS 15
Hello. After installing iOS 15, a green shade appeared on dark gray colors. Is this a software bug?
iPhone 12, iOS 15
I have not come across that in testing,
First try a Forced restart

If no better
You should arrange a service or repair

Anything other than Screen or Battery may be a replacement phone and the price is in the article.
If not covered by warranty and you don't have AppleCare+, you may have to pay full replacement cost for severe damage
