When im watching a video such as in the music app and double tap to zoom in full screen theres a purple fade that appears in the transition. There are also purple lines being left on the screen when scrolling through settings in dark mode. I have just reset the phone to factory settings and the problem is still occurring.
iPhone 12 Pro, iOS 14
This is due to the OLED display. The pure dark background reflects pixels being turned off, when you scroll to areas brighter than pure black those pixels turn back on but due to the speed limitations of the OLED display, pixels simply can’t turn on fast enough causing those purple lines.
In other words, this is totally fine and it’s not an iOS problem, simply the display’s limitation. Hope that helps!

My phone has the exact same issue. So I tried to find the cause in settings. And I think I found it! At least for me the purple fade doesn’t occur anymore when I turn off Auto-Brightness. I haven’t seen it ever since. I think Auto-Brightness may cause this issue.
yeah it can be minimised by tweaking software updates but it is a OLED thing also ... because other phones with OLED display also tend to show similar effects in dark mode .... before ios 14.5 it was less visible , i agree ... only after ios 14.5 i have noticed it ...
Hey, sorry just hopped back to check this thread
On light mode (white backgrounds, Home Screen, web, basically anything that is not pure dark and is being moved fast) it doesn’t happen because every pixel is lit. This minimizes the effect because everything has a brightness value. Those pixels are already on. Also, do a quick search online… Apple has two manufacturers for the 12 series and one of their displays suffers from green tint.
Nonetheless, I’m Light Mode everything (or mostly everything) is lit therefore reducing the effect since no individual pixels have to turn back on in a fraction of a second and the coverage area is greater than the actual artifact and the display is already fully lit.
Idk if it made sense, I hope it sorta did. But check the article, also do some more general OLED display searches online, it’s very common
iPhone 12 pro ... instead you can use Light Mode ....
Nope, Genius Bar said everything looked okay with the phone and my follow up phone call with Apple support said to return it for a new phone since I’m in the return period. Based off how many people are having this issue I don’t think I’ll bother though, everyone I know with a 12 is having the same issue.
Extra Info: also this effect is more visible if you have a pure dark background and the subject on the screen is a dark grey. For example, the settings app.
the main background in dark mode is #00000 (Pure Black) which in an OLED screen reflects pixels being completely turned off and the table options are #1C1C1C (Dark Grey a.k.a “Nero”) this is when the purple lines become more effect while scrolling.
I had this problem on iPhone 12pro so I sent it back for refund and bought the pro Max and the same issue I think it may be a device wide thing on ever device as it’s off to have same problem on 2 devices I contacted apple they did nothing except told me to get a refund so now I’m stuck with a phone with purple lines in dark mode it’s so off putting they said it is likely fixed with an update but don’t hold me on that one
After asking around it seems like everyone I know with a 12 is having this issue. Hopefully we’ll get a software fix but if not maybe they’ll have a program like they did for the defective butterfly keyboards.
I have a 12 mini and this is so annoying! It seems like many other people are experiencing the same issue with the purple blur on the displays of iphone 12 series and its more obvious when using true tone,night shift and night mode alltoghether. I'm guessing maybe many people are ignoring this or havent noticed yet.
posted a link for everyone with the same issue, and hopefully a big update like the most awaited iOS 15 release will resolve the query.
🤟🏼
Hi man I’ve been having the same issue since I got my 12 pro aswell - especially when my phones in dark mode amd watching a dark video etc and was told to just update my phone like wth. Were you able to get the issue resolved?
Nope, still having this issue and just got the iPhone 12 Pro, 2 weeks ago. Went into the Genius Bar, they replaced the display however it still appear,s especially in my contacts app. I'm going back on this Wednesday to address it again.
Same thing happening for me. iPhone 12 mini 128gb
Dont return it I refunded and bought pro max and same issue occurred x
