Wow. Play a black video in a dark room, full screen and brightness at 30%... then hit the volume button! This is very bad.

Good catch. Each time I push a volume on my 12Pm button it flickers once (greenish). I tried to take a video but it is not visible on a video taken with my XR.
 
mine doesn't do this except when rebooting, the screen will flash once. but I can't replicate anything else in dark rooms, volume buttons, no green or anything

Needs to be a YouTube video in full screen mode with brightness around 30%. Try again, once the baby bar disappears you’ll see flickering. If your screen does it on boot it will do it in this scenario - at the same time, hit the volume button! You’ll be in for a shock.
 
IMHO in youtube the green stripe when changing volume is a software bug, because you can take a screenshot of it.

Strange.. Same on rebooting device?
Completely black around the Apple logo even when rebooting.

edit: Actually, this phone still has raised blacks in some scenarios. It’s just much harder to see than my previous phone, so I thought they were gone. I also noticed by comparing two phones that the raised black behavior changed between iOS 14.1 and 14.2.1. In some areas a phone running 14.1 had no raised blacks, but another phone running 14.2.1 did, but when I updated so that they were both on 14.2.1, I repeated the test and the two phones matched.

Thanks for checking it again.

Still can't decide whether it's SW or HW related though.

I'm pretty confident every device has this, but the only thing's been changing is the behavior as you 've already said.

I just tested this with my 12 Pro received this weekend...there is definitely a "flash" if you change volume or bring an onscreen GUI element up during that black screen video at a limited range of brightness settings, but with mine at least it isn't green and it's very mild. I'm on 14.2.1 and the phone is otherwise perfect so far.

I honestly can't imagine how this is going to bother me in normal usage?

It kind of reminds me of early issues with LED televisions, with local dimming of the LEDs to try and hit blacker blacks leading to ghosting and other visual artefacts. I'm pretty sure it's a hybrid hardware/software issue that can be improved or eliminated by Apple if they put some time in.

If mine was flashing super green like some of the images in this post I'd be unhappy though so I fully understand people's disappointment.

Same here. I have not noticed it once unless I do the tests mentioned here and even then its minor. Would be nice if its fixed though. OCD thing for such a pricy phone.

Is it even confirmed that it's a software issue though?
It has to be, on boot you have a period of time when it does not occur, indicating the panel is not the issue itself.

Seems like this is an intentional feature to reduce visible ghosting/smearing.

Try scrolling through settings really fast in dark mode on a 11 or XS. It smears quite a bit. Try the same on the 12. It does not.

Seems like the pixels instead of being off are being kept in a somewhat ready state.

I imagine the thought was that no one would really notice/care, but they would notice and care about no more smearing.

So tell me, if it is a feature, why apple dont say it to us? and how you explain, that there are iphones from the 12 series, which does not have this flickering, not even when the iphone boots up?
 
I think it's pretty obvious that 14.3 will not fix this issue.

In the other hand we don't know for sure if it's HW or SW related, until Apple speaks.

Because it’s Apple. They don’t tell people a lot of things. Especially small obscure things that 99% of the customer base don’t care about or understand. Hell, if they told people about this it would probably just yield a bunch of YouTube goobers making 20 minute puff pieces about how Apple bad to gain views and take in ad money.

I think anyone with a 12 saying they don’t see it are just not noticing it. I’ve yet to see a single one without said issue.

Im in contact with some german youtubers (for Apple products) and asked them if they have this issue, they told me no. all of them were aware of this issue but did not have it. i would believe they tried hard to see it.

and even apple said this is an issue and they want to fix this with a software fix, tells us, they dont want it to behave like this, or am i wrong?

if it is a software thing, and apple want to prevent smearing, then why the old iphones with OLED dont behave like that?

Which German YouTubers are you in contact with?

Because not all iPhones get the same updates?

Updating my phone, it does not happen the entire time during the process. Ergo, it is not a hardware issue, because at a basic level the hardware is functioning correctly. Seems like on the 14.3 Public Beta that just released, the issue has been resolved on my iPhone. It's not happening anymore.

It's pretty easy to connect the dots.

I'm not sure why you have such a desire for this to be a serious problem, but it's pretty easy to figure out that it's just a software glitch and it will eventually be resolved.

It's not that simple. 11 Pro/Max or the older iPhs with OLED and running iOS 14 don't have these issues.

It's clearly something wrong with the new screens.

I don't know if it's a calibration thing, or a HW thing. Actually no one knows and everyone makes guesses.
 
I’m surprised Apple hasn’t made an official public statement about this yet. I returned my 12 Pro a couple weeks back right before my return period was over because I didn’t want to take the risk of Apple not addressing the issue at all. With Raised Blacks, iPhone 12 lineup right now is basically like an LCD screen with the drawbacks of OLED, the worst of both worlds. If the final 14.3 iOS build doesn’t resolve this, then I’ll be convinced it’s hardware. All OLED iPhones prior to the 12 Lineup running iOS 14 don’t have “Raised Blacks” (on this large of scale). I will definitely purchase a 12 Pro again if/when this gets resolved.
