iPhone 12 Pro iPhone 12 Pro “raised blacks” display

The first time I saw this forum I did the test and it was awful, really bad and I just wanted to return the phone. I tried to fix it obviously without getting it but after turning True Tone off and night shift off I restarted the phone (volume down and unlock button pressed) and saw true blacks, then a flickering with grey background and the black again just before the unlock display. It did not fix it but now it is very very subtle, almost non existent unless you want to look very deep into it. I hope it is SW but for now I’m pleased my display is not as bad as I see in other posts as well as the time I got the phone.

Edit: doing another test side by side with my wife’s XS Max, True Tone and night shift off I see my 12PM has a greener tint. I really don’t know if this could be fixed by software but I hope so as I don’t live in the US and would be very difficult to send the phone if there is a recall.

I saw it on my Pro Max and sure enough lots of people online confirm the bug is on Pro Max too.
 
I noticed that when I did a really dark night shot where light is barely visible, in the photos app, the screen always stays grey, even if I boost up brightness to 100%. I did not have auto brightness turned off, but grey stays always visible at any given brightness, a true black picture under same circumstances dims the screen at 100% to true black, but as soon as any little light is in a dark picture it stays grey in the photos app. I really hope for a solution from Apple soon. It takes them quite some time to figure this one out :( even if they recall all the phone I guess they don’t have the capacity to fulfill the requests for exchanges fast enough.
 
Same thing here. Here is what is see True Tone on or off.
-Brightness min: green/grey tint in the dark. Not flickering.
-Brightness from @25% and above : same tint and flickers once or twice b/w dark and the green/grey tint.
-@100%’ : pitch black not flickering.
I have tried to take a video with another iPhone (iPhone XR) but it does not render anything visible.
Edit: it does not flicker all the time...
 
Is this the issue ? With Reddit in dark mode I’ll click a post. The phone will flash like once or twice before settling down. In dark mode. Reddit is the only app that does it
 
My 12PM has supposedly the best Samsung panel(Display Serial Number starting with G9N...) and I did not notice the light bleeding with multiple attempts and was very happy.

Then I kept my wife’s Huawei P30 Pro side by side, playing the black video. And there its evident. P30 pro is stark black and 12PM has kind of faint residual backlight/fluorescence on the 2/3 part of the screen from bottom in irregular pattern.

Although in my case there is no flickering, and it’s more a kind of backlight bleed / fluorescence.

I can see flickering on videos. The problem manifests in full spectrum.

So the issue seems to be widespread. And the blacks in the videos which I often watch before sleeping with lights off, do sometimes seem like greyish/green.

And that is a discomfort for me in about 45-90 mins of screen time almost every day.

But I wonder how could this be a hardware defect in panel itself, as LEDs can not behave in this fashion, may be there is some issue in display chip.

I hope they can fix it with software update.

I have this problem with my iPhone mini , what are the chances this can be fixed with software?
 
Have the same on my 12 PM, flickering and raised blacks.
The 12 (non pro) I had before didn’t have the issue.
 
My husband’s 12 Pro Max and my now returned 12 had raised blacks.

I honestly forgot about this issue for a few days as I enjoyed my new green 12 mini.

But I switched to a pure black background wallpaper to help extend battery life and lo and behold, it is a moldy blotchy dark green. Ive used this background on my 11 Pro and it’s pure black like it’s supposed to be.

I haven’t tried the video test on the mini. I don’t plan to since it’s bad enough my background looks like this.

I’m bummed because I escaped the touch screen issue thanks to my think screen protector. I consider my phone otherwise flawless. But it can’t show pure black. I can see this even in normal room lighting. I made sure True Tone and Night shift are off.
 
This has been an issue that has plagued Android phones with OLED Displays in the past. It's definitely a panel issue/characteristic and each one will have varying degrees of it. If you just Google "Samsung Galaxy Green Tint" or "samsung galaxy uneven uniformity", you'll see it going back to the S3 and see tons of instances of it. LG had a couple of panels too that were horrible in that regards.

I have it on my Mini 12, but I only noticed it when I was testing for it in a pitch black room so it doesn't really bother me. I have yet to notice it under normal operating conditions. I used to test for it all the time on my Android phones with OLED screens after seeing forum posts like these and making myself crazy (and always had it to some degree or another on most devices, and as an Android developer, I have owned tons and tons of Android devices with OLED screens), I haven't tested for it once since I switched to an iPhone from the X to the XS to the 11 Pro. This is the first time in years I tested for it.

It’s on my mini to some extent but I don’t notice it for most of what I do on the mini. I did switch to a different black background that works better.

Thanks for adding more perspective to this situation. I didn’t realize it is an issue that’s been around.
 
I think you’re confusing uniformity issues on 5% grey with this issue. Yes, uniformity issues affected early OLED panels and even the iPhone X, but this issue is different. This is on 0% full black backgrounds where the pixels should be completely off but they are lit grey/green. Quite a unique issue and totally defeats the point of OLED. It’s a very obvious issue on all 12s unless it doesn’t bother you.

This issue does does seem to bother a lot of people when I see there are only 11 pages of comments here. Way less than the yellow tint thread. I have the raised black issue and I guess I’ll wait Jan 8th my return my deadline. If most people don’t care Apple won’t care.

I have raised blacks too on my 12 pro max. Black images are grayish and uneven. Also there is flickering, as if the screen is trying to switch pixel off. My return deadline is over now. I don't think I even can prove it, the problem is visible only in full darkness.

I thought I was going crazy. I use dark mode on my iPhone 12 Pro 24/7 and my blacks are not OLED black. Plus my screen flickers! Does anyone here know if this is a hardware issue?

Not everyone, but it looks like 95% of the people has this problem (including myself - iPhone 12) When I restart my phone the apple logo will appear with a perfect black background and then switch to the ghosty grey/green only noticed in super dark environments, but it's present. I tend to think that this is a software issue (speculation)

I had Samsung Galaxy S3 in past, and I can confirm this. Mine is having slight green around left bottom corner.

My recent Android is Sony Xperia XZ3 and thankfully I got perfect panel thus not exhibit those issues. True all uniforms pitch black, all dark pixels really turn off when black screen displayed.

That green issues usually happened on early generation OLED screen. In past Apple sticks to either Samsung or LG panels, I am curious what kind of panels which Apple use for iPhone 12 which causing so much display lottery.

12 Pro Max here. Same issue wth raised blacks, mostly on rebooting device.

You can barely see it with a total black wallpaper. Just for a second.
 
I got a replacement Pro Max due to a different issue and the replacement doesn’t have this issue. I could easily reproduce raised blacks and flicker on the first phone, but can’t on this new one.
 
Not on topic but does anyone else have troubles with the temperature of their phones? My 12 pro gets warm with a few minutes of snapchat and very hot when playing arcade games such as samurai jack and the pathless.
Could you guys comment on the temp of your phones and the drops in fps for games?
please!
