Problem I have with my iPhone 13 mini

I am writing to express my deep concern and frustration regarding a critical issue I have encountered with my iPhone 13 Mini following the recent iOS 16 update. Upon completing the update , I immediately noticed severe display abnormalities on my device. The screen now displays erratic black, green, and pink colors, rendering the phone practically unusable. Despite multiple attempts at restarting and troubleshooting, the issue persists.Before the update, my iPhone 13 Mini was in perfect condition, and I did not experience any display problems. I am confident that the issue is directly related to the iOS 16 update. Please, Find a solution as my device is totally useless with this screen display
