[Google Pixel 4 XL Questions & Answers] dhorgas:
Okay so I was able to reproduce this issue at will now and can say exactly how you can test for it. Basic display settings are Ambient EQ On, Ambient Display Off, Smooth Display On (90Hz enabled), Dark Mode Enabled, Night-shift Enabled, November patch though I think the same issue affects the launch software but to a lesser extent. For ease of testing, turn off auto-adjusting brightness. Once you have this set, here is what you do to see the problem yourself (note that the settings I mentioned are just what I had set when I tested this so I recommend using the same so its apples to apples comparison):

1. Make sure you have the default wallpaper set for this test since it is the easiest to detect issues with it.

2. Pull down the quick settings shade, drop the brightness slider all the way to zero, then close the quick settings.

3. Turn off the display by pressing the power button, wait maybe 5-10 seconds, then turn it back on. You will notice that the screen (at least in even a moderately lit room) is barely readable. It should now be red-shifted.

4. Pull down the quick settings again and start moving the brightness slider from 0% to 100% slowly, then repeat the process of moving the slider back and forth for a bit and note the colour changes. You will notice that the true-ish gray will be somewhere around 75% brightness or higher. Anything below this will start to red-shift quite severely (your grays will look more red/purple).

5. Set the brightness slider to 100% and close the quick settings, then swipe down to open them again.

6. Start moving the brightness slider from 100% towards zero and pay attention to the screen colour. You will notice that true gray quickly starts to degrade to greenish-gray, then quite severely green, until finally the brightness collapses severely around 10%-15% of the slider. Your display is now severely green shifted and moving the brightness slider back and forth will just show this effect switching to true gray around 70%-75% and up, and to severe green shift for anything below that.

7. Finally, drag the brightness down to zero again, then turn off your display via the power button. Turn on the display again and move the slider around again. Your display is now no longer green shifted, but it is now red-shifted. Repeating the same steps over and over will result in the same behaviour, back and forth red-shift when screen is turned off with brightness at zero, green shift when brightness is turned down after the device engaged 90Hz refresh rate and so on...

I actually recorded a video of this happening and will see how I can share it with Google.
[Google Pixel 4 XL Questions & Answers] jbartley88:
So glad I found this post, I thought I was the only person experiencing this. do we try and exchange the device? Or wait for a software update?
[Google Pixel 4 XL Questions & Answers] dhorgas:
I am actually talking to Google as I type this. I sent them my video and they confirmed the problem. They are escalating it now with all of the detail that I have provided so far, but they cannot tell me if or when it will be resolved at the moment. They are not stating that this is a hardware issue or an issue with my device. They believe that it is firmware/software, introduced or maybe made much worse by the November patch. I did inform them that the issue existed with the October patch, but it was made much worse with the November patch. Interestingly enough, while testing with them we confirmed that the green shift occurs even if smooth display is completely off or the smooth display is forced on. Turning off smooth display eliminates most of the red shift (though not all).

To answer the latter part of your question more specifically - this could end up being similar to the Pixel 2 XL POLED fiasco so there may not be a way for Google to fix this in software. Whether you are willing to take that risk is up to you. I am going to send my device back and am trying to get the Google dev team to update me on the progress of the issue regardless. At some point in the near future I'd like to be able to re-buy the Pixel 4 XL free of this problem.
[Google Pixel 4 XL Questions & Answers] Reuben_skelz92:
I wonder if rooting and putting kurisuka Kernel would hekl
[Google Pixel 4 XL Questions & Answers] dhorgas:
Perhaps but those days are behind me. I simply don't have time to do this any more. I need the device to work solid out of the box. If you have the Pixel 4 XL, were you able to follow my instructions and reproduce the issue?
[Google Pixel 4 XL Questions & Answers] Reuben_skelz92:
Didn't make a difference, I got the white point better to how I like but the green tint bug is still there, deciding weather it's a deal breaker or not, it's really annoying
[Google Pixel 4 XL Questions & Answers] elreydenj:
What settings did you use in color control to get the white point you like?
[Google Pixel 4 XL Questions & Answers] pixelsquish:
i agree with not having time, I don't have the time to try to replicate this issue. I use my phone in my bed in the dark all the time, with a dark theme and low brightness and don't have an issue that i've noticed.
[Google Pixel 4 XL Questions & Answers] zetsumeikuro:
Same thing happens on the one plus with 90hz it's limitation of the current tech for oled panels. If you can't put up with it just return the phone but it's not Google's fault, nor is it limited just to the Pixel 4s.
[Google Pixel 4 XL Questions & Answers] dhorgas:
I’m not sure if this was a genuine comment or a snide remark. Either way, it takes a few minutes to try the instructions and see. The more people report this the faster Google will fix it.

Google’s reps disagree. Since I spoke to them they have indicated that this is not normal behaviour and the issue has already been escalated to the dev team for review. That does not mean that a fix is forthcoming anytime soon, but the issue is definitely there. There is no reason to excuse lazy programming.
[Google Pixel 4 XL Questions & Answers] zetsumeikuro:
I would take everything and anything a Google rep says with a grain of salt. They say this about any "issue" that people call in about just to get them off the phone so they can continue answering calls to meet their quotas. I'd sooner believe someone telling me the sky is pink before I believe what a Google rep tells me on the phone. But one can definitely hope that they can software patch this issue which is unfortunately probably a limitation of the oled tech at this point and time.
[Google Pixel 4 XL Questions & Answers] dhorgas:
For what it’s worth, there was no rushing of the discussion at all. They reviewed everything I submitted, video included, and they also had me try out several other combinations of settings on the phone so we can document all of the scenarios under which the issue occurs. We were proactively talking for about one hour and a senior rep was also involved at the same time. So no, in this case I don’t believe there was anything disingenuous. They really did troubleshoot and took time to understand, then escalate the problem.
[Google Pixel 4 XL Questions & Answers] zetsumeikuro:
Nice, looks like you had the exact opposite of an experience that I did. Perhaps they implemented some new policies because when I called in about the purple tint/hue on my 4 XL with 90hz forced they just gave me a replacement after doing a factory reset. Then with my 3XL they didn't really seem to care about the noises from the earpiece during phone calls with VOLTE enabled in areas with poorer signal. Just kept sending out replacements that all had the issue. There was inconsistency with the reps and they would all tell me different things it was pretty annoying and they had zero accountability. Hopefully your support experience will be the norm from now on.
[Google Pixel 4 XL Questions & Answers] Reuben_skelz92:
Never had this issue on the OnePlus. I think there is something wrong on the pixels, I mean it's not a bit it's a disgusting green hue across the whole screen
[Google Pixel 4 XL Questions & Answers] zetsumeikuro:
There are threads out there some on xda and some on reddit about green tint on the 7t and 7 pro to varying degrees. Simple Google search did the trick.
[Google Pixel 4 XL Questions & Answers] Reuben_skelz92:
I did a search and there not the same. Most are the 7t which uses a cheaper panel. And any I saw looked more like hardware issues as the tints were uneven
[Google Pixel 4 XL Questions & Answers] zetsumeikuro:
Samsung did the displays for the 4 XL so anything is possible when it comes to the panel quality. Samsung doesn't necessarily equate to quality/perfect panels. I'm assuming Samsung also did the panel for the 7pro? Or was it another manufacturer? Would be quite hilarious if they gave Google subpar panels and gave One Plus higher quality ones.
[Google Pixel 4 XL Questions & Answers] Reuben_skelz92:
Yeah I know. To be fair any oled can have uneven tints etc, even Samsung devices themselves. No I do believe Samsung made the OnePlus ones too
[Google Pixel 4 XL Questions & Answers] dhorgas:
Well, Samsung can be binning the panels (I'm sure they do in fact). Apple gets the best panels without a doubt. Sometimes I feel that Samsung provides better panels to Apple than it does to Samsung Mobility. I dropped off my Pixel 4 XL to UPS today to return but I am hoping this gets resolved so I can pick up another one soon. The overall look and feel of the device was really good IMHO, and I enjoyed the pure Google experience but the display was a deal breaker.
[Google Pixel 4 XL Questions & Answers] Ady1976:
Because display mate is sponsored by Google, there is no way in hell this display is A+ as display mate say my s10+ pisses all over it.

And yes no play store calibration app works they are just filters and can't change hue or colour profile without rooting which is not an option for me, i shouldn't have to root my phone to change colour profile as i don't with my s10+ I replaced the 4xl with.
[Google Pixel 4 XL Questions & Answers] Reuben_skelz92:
Even the oneplus 7 pro display was much better than the pixel
[Google Pixel 4 XL Questions & Answers] xFirefly93:
".. Battery life is poor.."

Please, hold my frosty beers please for a second.
[Google Pixel 4 XL Questions & Answers] Ady1976:
Haven't seen the op7 pro in person but from what I'm hearing yes it's better than the 4xl, quite disappointing from Google to be honest.
[Google Pixel 4 XL Questions & Answers] Langduscher:
Sorcery :cool:
[Google Pixel 4 XL Questions & Answers] xFirefly93:
This is sorcery, if anything.

:highfive:
[Google Pixel 4 XL Questions & Answers] Reuben_skelz92:
It really is. Even though I'm not wowed by anything it's a solid phone and I would have been switching but these poor quality panels is a deal break.

The 7 pro even though had annoying curves, it had way better white point, no weird tints , was uniform and black crush was a lot less
[Google Pixel 4 XL Questions & Answers] dhorgas:
If you want to post about battery life with rooted phones and custom kernels you are in the wrong thread and wrong section of the forum.

Also, battery life wasn’t the deal breaker. Terrible display calibration at lower brightness levels with no forthcoming fix is what did the phone in for me.
[Google Pixel 4 XL Questions & Answers] Ady1976:
Yeah I was very tempted by the op7 pro just the camera put me off to be honest.
[Google Pixel 4 XL Questions & Answers] xFirefly93:
Then stop complaining about 'poor battery life" and calibrate the screen yourself with the KCAL kernel feature.

End of story.
[Google Pixel 4 XL Questions & Answers] Reuben_skelz92:
The screen still looks rubbish even with root and calibrating so...

It's a good camera tbh. Not pixel good but more than good enough unless you need the best of the best camera
[Google Pixel 4 XL Questions & Answers] HipKat:
I don't see any of this. I have 90 on, AOD on and no crushed dark, no green tint. Of course, AOD is a big battery drain so I keep it off during the week when I use my phone for work
[Google Pixel 4 XL Questions & Answers] RoccoN4:
Ya I don't see this green tint thing either. I have everything on as well. And if I am in a dark room where I need to lower the screen brightness, I'd naturally expect the screen to not be as clear or colorful as when compared to high brightness.
[Google Pixel 4 XL Questions & Answers] Ady1976:
Yeah they're all half decent anyway these days, I'm happy with the s10+, prefer stock android but it's something i can live with.
[Google Pixel 4 XL Questions & Answers] dhorgas:
I actually don’t know what to say to this level of nonsensical commentary. Surely you should see just ridiculous this sounds. Nobody, not even on XDA should consider this an acceptable solution. With that said, I think I’ll just refrain from commenting further on your posts.
[Google Pixel 4 XL Questions & Answers] jbartley88:
I feel like my screen has got worst... Here's a comparison with my pixel 4 xl and my Mrs p4xl
[Google Pixel 4 XL Questions & Answers] Ady1976:
Hey I feel you, according to some folk this screen is great, i can see that has the exact same issue i had with the ****e i sent back, blurry text and tinted, it's Google and the panel lottery plague again.

---------- Post added at 10:23 PM ---------- Previous post was at 10:20 PM ----------

To be fair agreed completely on this, why should people root their devices and risk warranty when it might not even fix the issue from what I'm hearing.
[Google Pixel 4 XL Questions & Answers] Reuben_skelz92:
Looks like mine. It's awful and makes the phone unusable
[Google Pixel 4 XL Questions & Answers] dhorgas:
This is exactly how mine looked as well. Intolerable for a $1,500 CAD phone. Even budget phones don't have this bad of an issue. I went today to check out some other Pixel 4 XLs in the mall and some of them had the green screen issue, others didn't seem to. More did than didn't. Nothing scientific about it but randomly sampled nevertheless.
[Google Pixel 4 XL Questions & Answers] HipKat:
Wow!!! Yeah, mine is nothing like that. Totally clean, crisp and clear
[Google Pixel 4 XL Questions & Answers] zetsumeikuro:
Wow, that is pretty terrible.. I would get a RMA if you haven't already requested one.
[Google Pixel 4 XL Questions & Answers] RoccoN4:
Without comparing phones side by side how could one tell. My phone looks fine but could be because I have nothing to compare it to.
[Google Pixel 4 XL Questions & Answers] dhorgas:
That's the thing, it is a complete lottery it seems on what you will get. In the local mall yesterday I saw devices with and without the issue. All had crappy handling of black at low brightness but at least some were not turning green in the process. An RMA isn't particularly likely to fix it either considering that (at least anecdotally) most of the devices I looked at so far had the problem. There have also been at least a couple of reports here and Reddit of people replacing the device and ending up with the same problem.
[Google Pixel 4 XL Questions & Answers] zetsumeikuro:
I've been through two and both of my devices never looked like that. OLED is always a lotto thats for sure, but thankfully Google's exchange process isn't too bad if you can do the advanced RMA. Personally, I'd say it's worth it to try a few times and see if you get lucky with the OLED lottery. But if not hopefully it starts to look a bit better over time after it breaks in a bit.
[Google Pixel 4 XL Questions & Answers] m+a+r+k:
Wow, send that back immediately, that's ridiculous!
[Google Pixel 4 XL Questions & Answers] jbartley88:
I've exchanged mine now, ans so far so good, I'm just anxious to do the November updates as I have seen people complain that it has gotten worst post November update
[Google Pixel 4 XL Questions & Answers] dhorgas:
Can you post the same comparison as before? Also, can you install the November update and see what happens? Realistically it's not like you can keep you phone on the old patch forever and if its broken its broken.
[Google Pixel 4 XL Questions & Answers] jbartley88:
Did the update and the screen went back to the green screen so I'm assuming this is a software issue as the screen was perfect until I did it
[Google Pixel 4 XL Questions & Answers] dhorgas:
This is good information. Perhaps there is hope for a fix yet :)
[Google Pixel 4 XL Questions & Answers] sharkoparko:
Every year display issues with pixels, crazy!

I have no green screen, but that calibration is so yellow/warm so I even checked once if I have night mode turned on :). Sitting next to my note 9 screen looks trash. whites are not white, either grayish or yellowish depending on brightness. Love the 90 hz but this so warm display is killing me. [ and got twice message "memory running low, close background apps"!! seriously ?!? never had that with a note 9 ]

Great specials on Note 10+ in a week from Costco and Microsoft store. last one $200 off free wireless buds and $500 trade in note 9. But still 60 hz, although amazing display

Convince me not to get Note 10+ :)

Anyone shuffled back and forth fron Note 10+ to 4 xl??
[Google Pixel 4 XL Questions & Answers] dhorgas:
I've shuffled back and forth from S10+ to 4 XL. I actually prefer the 4 XL in almost every way functionally (two exceptions being the ultra-wide camera that the 4 XL does not have, and the S10+ quality of the front-facing camera). However, the display issues were a deal-breaker for me on the 4 XL, and to a lesser extent the very average battery life that caused battery anxiety. Hence, the 4 XL was returned until such time that Google resolves at least the screen issues and the S10+ remains.
[Google Pixel 4 XL Questions & Answers] HipKat:
This is mine after the November update, still no "Green" screen
[Google Pixel 4 XL Questions & Answers] zetsumeikuro:
Would have to take a picture of the screen as it would be a hardware issue and it won't show up in a screenshot.
[Google Pixel 4 XL Questions & Answers] HipKat:
There's nothing to show up. That's exactly how it looks irl
[Google Pixel 4 XL Questions & Answers] zetsumeikuro:
Gotcha, honestly for most the green tint will only show up under circumstances and quite rarely. Would only be in lower darkness settings with smooth display/90hz enabled. Others apparently have it all the time under every circumstance. I feel for some Google can do further calibration via software updates and others will solve the issues. Others having the problem all the time maybe an exchange will be their only course of action.
[Google Pixel 4 XL Questions & Answers] dhorgas:
Has anybody read the Pixel 4 series display analysis posted recently at https://www.xda-developers.com/google-pixel-4-4-xl-display-analysis/?

The section on Contrast & Tone Response hits the nail on the head on one of the major issues I observed whose root cause I didn't understand. Looks like the Pixel 4 XL gamma completely collapses at lower brightness levels. I noticed that below 10%-20% all shadows are crushed and anything displayed on the screen becomes basically impossible to see. This is discussed in the article from a scientific standpoint and looks to specifically plague the XL variant.
[Google Pixel 4 XL Questions & Answers] HipKat:
One thing ,why would you turn your brightness down that low? I keep mine on Adaptive, which leaves it in the 40-50% range
[Google Pixel 4 XL Questions & Answers] EeZeEpEe:
Yes the review says "at minimum brightness, the Apple iPhones and the OnePlus 7 Pro are still superior in black clipping than the Google Pixel 4" but it also says "Improved black clipping compared to previous Pixel models, with notable significance in the Pixel 4". Coming from the Pixel 2 XL, it's a huge improvement.

I personally set my brightness to 0% in pitch black because I hate a bright screen in dark environments. The black clipping is hardly noticeable compared to the Pixel 2 XL which had to be around 40% or higher to compensate for it.
[Google Pixel 4 XL Questions & Answers] sharkoparko:
Great article. The only good thing with that display is the 90hz, otherwise can't touch latest Samsung.

And what we saw is one needs to be full 100% brightness to have somehow decent display. And that's how test were done. That's what I noticed, I can maybe live with this display only in 85-100% brightness slider position. The brightness doesn't give you uniform quality of screen, and not just in the low 20s, less than 85 everything starts going downhill.

The articles also talkes about grays. Or as some call it Haze\dirt\noise on screen etc.

Bottom line it's a dim display tuned warm and the range of ambient eq warmness goes to only 6700ish while Samsung was in the range low 6000 upper 7000, so in a daylight condition you might benefit in the 7000+k even though "experts"tell you 6500 is there natural.

I think I saw somewhere that oled gets brighter-cooler with time due to glue curing?!, that might be true after few months, as the end of my phone cycles I think the do look cooler
[Google Pixel 4 XL Questions & Answers] Ady1976:
Did you get a replacement and have you had a refund yet? It's 3 weeks this Thursday and still not had a label for returning the replacement for a refund, have reported Google to my bank and they are charging them interest for pissing me about, that's 1 customer they've lost for good, never again, their support system is abysmal when things go wrong.

Update.

Scrub that just had the 2nd label after a 3 week wait, never again will i purchase anything from the Google store.
[Google Pixel 4 XL Questions & Answers] dhorgas:
I did receive a refund for the phone. However, they still owe me a refund for the case and it’s been a week already with no movement, not even notification that they received it and processing it. I do know they received it since it was shipped with tracking and it was delivered.

The Diamond and geotag my pictures.

Is this possible ?

And how ?

i looked at the registry tweak

HKLM\Software\HTC\Camera\P9« DWORD-entry »Enable« to 1.

But on the P9 is already something on, better not change this i think it's has something to do with video.

So is there a other way or tweak for my diamond to geotag ?
