Hi, Please see the below images: From left to right (bottom to top in 2nd image): iPhone 6 Plus space grey, iPhone 7 Plus matte black, iPhone 7 Plus gold. All phones are set at maximum brightness. So as you can see, with the dark gray image in Safari private browsing mode, I get these horizontal lines & changes in gradient on the bottom half of the screen for the iPhone 6 Plus space grey and iPhone 7 Plus matte black. It's very noticeable in real life. Weirdly, I tested it on another iPhone 7 Plus (the one on the right) and the lines are completely absent. The lines also appear for both phones in the 'Enter passcode' screen, when I select the last wallpaper in the 'Stills' category (the dotted gray wallpaper.) I can also see the subtle shifts in gradient on the bottom half of the actual wallpaper. The lines are also visible in the Wallet app -- see 2nd image. I can't seem to replicate the horizontal lines for the iPhone 7 Plus on the right, under any condition. However, I tested other gray wallpapers from google image and the lines don't appear on any of the iPhones... I noticed the horizontal lines on my matte black iPhone 7 Plus and compared it to another gold 7 Plus, which again didn't have the lines, so I figured it was a screen defect. I called Apple to arrange a replacement. I then decided to check my older iPhone 6 Plus and lo and behold, the lines were there. So now i'm not sure if I should cancel my replacement request if this is supposed to be normal? Are people able to replicate this on their iPhone 7 Plus? I believe you can only get to that "Private Browsing Mode" gray screen if you close all windows/tabs in Safari and you don't have any bookmarks/favorites. --- Post Merged, Oct 12, 2016 --- Another strange thing, which makes me think it's not the actual display: When I change to landscape mode, the lines follow accordingly: But what makes me scratch my head...why can't I see these lines on the iPhone 7 Plus gold?
