iPhone 7 Plus: Are horizontal lines on the display normal using a gray image?

    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.

    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?

    So I just stopped by my local Apple store and the first iPhone 7 Plus I checked, I was able to reproduce the horizontal lines using the same screen. I figure this is normal so I cancelled my replacement request. Again however, it's weird that the other iPhone 7 Plus I have access to doesn't have these lines.

    It's not normal, get it replaced. The lines following accordingly is a sign it is the display. What else could it be?

    I figured if it was an issue with the display, and the gray screen is supposed to be completely uniform (sans any sort of banding), then shouldn't the lines stay in exactly the same position, even when switched to landscape mode? My first thought was that the bottom half of the screen was defective. Now after switching to landscape mode, my assumption changed to 'it could be dependant on the UI.' Like some sort of color gradient inherent in the design that manifests itself in this particular screen.

    So far, 2 out of 3 of the iPhone 7+s' I've checked, and my older iPhone 6 + shows the same lines. This is all on IOS 10.0.2 with maximum brightness. I will check more of the 7+'s at another Apple store to see if this remains consistent.

    I forgot to make it clear: first you have to change the wallpaper to the last wallpaper in the Stills section (the dotted dark gray one.)

    Thinking about it more, it could very well be an issue with the display...as this image can be the effect of a dark gray luminescent window over this specific wallpaper.

    So has no one else been able to replicate this issue looking at this private browsing mode screen in Safari? Please post your results.

    Yeah, that's the conclusion I came up with in the post above yours. Just want to be 100% sure though.

    And again, it's weird that one of the iPhone 7+s I checked doesn't produce any of these lines. Wallpaper is the same and icon layout is similar.

    That's why i'm asking if people here can test it out on their iPhones.

    I get it too on all three dotted wallpapers - but it's definitely just an anomaly caused by the transparency of the dotted wall paper and nothing to worry about - it's the rendering of the dot frequency or something like that!

    There's 2 simple solutions that are easier than returning your phone......... Use a different wallpaper or turn off pron mode
