iPhone 4 Interlacing effect

Hey guys,

Just got a new black iPhone 4 16GB the other day along with my girlfriend (She got the White 16GB). After only a few hours of use I started to notice these weird interlacing/scan lines showing up on the phone.

They predominantly show up best on a higher brightness level + dark background, but can be seen almost all the time when you're changing focus from one item on the screen to the next. This post here shows exactly what I'm talking about. Seeing them is quite disappointing in two ways. First, it makes me feel like I'm getting an inferior product than I was expecting, and second, because it's distracting when you're using the phone to see these lines pop up whenever you're looking around the screen.

I've checked my girlfriend's phone, and this issue is non-existant. Her screen is nice and smooth, with clean corners and no sign of any interlacing. I've already called up AppleCare once, and even went to the Apple store and had the phone replaced. The new phone is having the exact same issue, while my girlfriend's remains crystal clear.

I've set up another callback appointment for tomorrow to let them know it's still going on, but I don't want to seem like I just have OCD or something.

Has anyone else had this issue before/resolved it in any way? I'm currently running 4.3.3.

Thanks

iPhone 4, iOS 4.3.3

Hi r.d

I think we have to accept it. I check for my friend's white iPhone. They have this issue as well. Every phone of my friends which made since week 25 2011. have this issue. so it should be the problem of hardware. It's so sad I bought this iPhone to use instead of my old 3gs because I love retina display. Now I feel so bad everytime i pick up my phone and saw the display.

Dear Apple

Everyone can miss. Come on please tell us that you are doing something for solve this problem. you guy are focusing on iPhone 5 I know. but you aren't small company. please let someone take care of this problem.

I got my replacement phone today. Another week 32, running 4.3.3. I'll update it tonight but so far, it seems to be working. I'm going to check other iPhones my friends have this weekend. I can't imagine not noticing this problem. I showed one friend and he saw it right away.

Hi r.d

How is going? I think you can't notice the interlace line in normal situation. please try to load the image via link below

https://discussions.apple.com/content/attachment/24296040

and then save it into your camera roll. if you open it your iphone display will flash/flick very bad 😟. you will notice it easier when you set that image as wallpaper.

I have another experiment. I keep the display blacklight on when i charged the iPhone, after a while, The flash/flicker had gone. but when I push it sleep 2-3 hours ago, the flash/flicker come back again. So I think this is the hardware issue for sure. May be Apple haven't used the good quality LED blacklight.

Yeah I can see some flickering on the image but this phone does not have the same interlacing problem I photographed. On my last phone, I could notice the lines on any screen. I wouldn't say flickering on one image is a major problem or use it as an indicator for the real interlacing problem. I don't see the flickering on any other screen.

I did check 3 other phones on the weekend and none of them had the problem I was experiencing so I don't think it's a very widespread problem.

Hi everyone

I bought a new iPhone4S 1week ago,and the interlacing still there.The good point is that its MUCH BETTER(very weak) than iPhone4,but I can also notice it anyway immediately after turn the sceen on,and it dispeared when keeping the screen on for a few senconds.

DO you guys buy iPhone4s,do you still have the interlacing problem?
