Are u sure that opx is true black amoled??
What if I say you ... that ..It has a backlight ..
Wanna verify?
Important: make sure u have brightness slider to near low levels. This backlight is not seen at high brightness levels.
Download a gallery like quickpic that lets u open a picture in Fullscreen mode so that picture fills entire screen.
Make a bmp image in ms paint in windows and fill it with perfect black. Or download from some website with hex value coding -enter zero for all numbers
Now load this picture in quickpic or any other Fullscreen gallery.
Switch off every light in ur room .make d room jet dark
Wait a few seconds for your eyes to adapt to darkness
U will see the backlight instead of black.
For more easy recognition see in peripheral field of vision, where low light vision is good. (Focus point of eye doesn't have low light vision ,am a doc.) (see somewhere else, bring in the phone into vision filed)
If u think the gallery is d problem.
Do this same thing in any other amoled phone. You will know the meaning of black.
(I did in Moto x ghost )
It's not a backlight. No AMOLED screen uses a backlight. That would defeat the whole purpose of AMOLED.
What happens is, even if the pixels are black (switched off), they are fed a tiny amount of voltage from the motherboard to allow quick switching of colors so they are never completely turned off. As a result, even when displaying black they emit a very faint glow.
I'm not sure if this only happens on pentile displays (like the one in the OPX and most Samsung phones) and I can't verify since the only AMOLED devices I own are pentile, but my Galaxy S3 Neo also has this "problem". Personally I wouldn't worry too much about it, since even with the glow the blacks are WAY deeper than any LCD display with a backlight can produce.

Thank God man.
I thought my phone is fake display.
Ur reply is proof that knowledge helps..
Btw just curious.. what are you?? How do you know this information not available in internet... So nice to see you man.
And regarding ur doubt, whether this happens in non pentile array amoled ...
NO.
I own a RGB amoled -Moto x ghost phone. It doesn't happen there.
I will check in moto x droid turbo . My cousin has it. So I will do and post results here.
And I wish to add this :
A 312 ppi RGB amoled (I have moto x ghost, 720p, 4.7 inch) is way better much much better than 440 ppi pentile amoled ( I have opx, full HD 5inch)
If I compare the images, they are much cleaner and sharper than opx . It's like the image has a depth, there is some stillness kind of feel. ...( I use colour control kcal, and so I test the displays in many settings not just default.
For example to make the images look similar as moto x ghost so that we can compare, I use rgb values as 32, 30, 27 value at 123, contrast at 121 and then slide the brightness slider to 3/4 or more.
Now both images look same in terms of how much dark areas are visible , the white wash noted in opx is now gone.
Now the images are ready for comparision.
Now the difference is the sharpness or clarity in rgb amoled. The feel difference i get is that there is depth in RGB. Its has a grip.

Hey, to shoot the question right away; is there a way to properly calibrate your mobile phone screen?
I've searched the forums and googled and haven't found anything I was looking for.
Preferably being able to load color profiles like sRGB or Adobe RGB directly.
I'm not reffering to simple RGB settings or Gamma tweaking.
The reason I'm asking is that I work in 16 bit float mostly and got a perfectly calibrated IPS NEC nicely working with a 12bit LUT and also 2 calibrated TN panel screens.
The final image goes to 8bit PNGs and JPGs with sRGB embedded.
Now the difference between the final outcome on the IPS screen and the TN ones and the one displayed on 4 different android mobile phones I got available for testing is extremely big. So big, that just everything is off.
I thought that embedding color profiles might cause this but using other common profiles or none at all still were extremely off.
I'd like to point out that the image is not necessarily bad, it's just wrong knowing how the end result looks on perfectly calibrated monitors at home or at work.
I'm just surprised that there is close to no information available on how to properly view imagery with embedded profiles considering that the internet is full of fancy mobile phone screen tests and benchmarks nitpicking every single micro millimeter on a screen light years away from normal use conditions.
(At least they don't take into account that probably 60-80% of the images average users view on their mobiles are crappily compressed Facebook .jpgs and the rest photographs shot on mobile cameras..but that's not what the thread is about.)
Is there really no way to counter factory presets?
It's like with TVs on factory or even worse shop presets with shiny oversaturated colors and crushed contrasts, but on TVs you got the chance to turn the crap off at last.
Any idea or guidance would be highly appreciated.
Bump.
I need to calibrate my phone's screen color too, I know I can't expect miracle from the screen of my Xperia Mini, but at least I want to have more natural colors on the screen, Bravia Engine doesn't help at all in color quality, it only increases the sharpness, contrast, and saturation, no better color reproduction at all.
I have SE Hazel, an SE proprietary OS powered phone (DB3350v2), with dispdriver.dat tweaking (only editing the strings for RGB gamma settings inside it), I can make it reproduces far better and more natural colors than my Xperia Mini.
I don't want to make my Xperia Mini screen has the same color reproduction as a calibrated IPS panel, I only want, at least it can reproduces more natural colors than it does now, I also know that even the same phone model don't always have exactly the same screen color reproduction.
From my searches so far, colour management seems to be completely missing in Android.
I'm a photographer and would like this too. I want to use my tablet to review photos, but the colour is way off.

my phone display produces too strong blue and red, less green, it makes most photos look far from natural.
I've noticed on hands-on videos that the Droid DNA has a blue tint on white backgrounds. Some reviewers have also mentioned this and the cooler nature of the colors. Another thing I've noticed is the colors seem less vibrant compared to the One X, which was more colorful and warmer. The blue tint was the first thing I noticed while all these review videos were extolling the greatness of the PPI. The blue tint on galaxy phones drives me batty, and this one might not be that different. Do you see the blue tint on your phones? My local Verizon store only has dummies. I might just wait for the Oppo Find 5. I really like how the screen looks on that phone.
One X was uncomfortably warm for me. Too yellow which I didnt like.
DNA is little more colder but colours still pop nicely. Much better contrast compared to One X that I had. It is right balance between what we have seen with One X and SMOLED display that my Note 2 has.
There is definitely no trace of the typical blue tint you see in AMOLED displays. It is definitely whiter than SGS3 and Note 2. But not as yellow as One X. It is perfect actually. You can never judge screen seeing videos. Choice of wallpaper, camera sensor and room lighting play huge role in how things look on camera. There is no doubt in my mind, this is best display I have ever seen on Mobile. PERIOD.
Maybe many reviewers are coming from One X which was considered to have best 720P display. But frankly for me it was too yellow to be natural.
Thanks for your reply. I have to disagree with you about not using videos to judge a display though. Every phone I've bought looks exactly like how I've seen it in videos. There are poor quality or off-color videos of course, but those are very easy to notice and disregard. With high quality videos, especially when you have the phone next to other devices that you've used and know how they should look, there's no room to blame the video. Apple's displays always look so good because they calibrate it properly. HTC and others need to take a hint. At least provide calibration software onboard if you don't want to do it manually for each device.
I've had a few replacements of the DNA for various issues and I noticed that they all had slightly different calibration profiles with whites of two of them being slightly red tinted and the others being either slightly blue tinted or in the case of the one I currently have, closer to neutral but the colors appear to be slightly less vibrant. They're all over the map, so I think it's just the luck of the draw. One thing I have found consistent is poor backlighting with shadowing on different edges of the screen on different units, especially the bottom (near the capacitive buttons). The pixel density and size is definitely phenomenal, but I miss the balanced calibration and completely even backlighting (to the edges) of my 4s.
No blue tint here.

Haha your posts all over XDA are just hilarious! The Alphas screen is soooo of far from the best out there..... The statement makes me laugh. Have a look with you eyes instead of reading alot of biast c**p.
Thats funny 'cause I chose the Z3C over the Alpha because of the Alpha's pentile matrix screen. Text wasn't as sharp as I'd like it. I guess you have to see it in person to believe.

I do a ton of reading. I said that Text don't show up as clear and that is something that each user has to see in person to verify since everyone's eyes aren't the same. A picture of a phone's screen isn't going to show that. If you can't see the difference, at normal distance, it doesn't mean other people can't too.

Goodbye man. I have ton of proofs, you have nothing
the screen is nice im not sure why the reviewers needed a 1080p screen. i came from the nexus 5 which had a 1080p screen and the screen on this phone looks better.
I shere your opinion,I came from S.Galaxy s4 also with 1080p
screen is briljant
Not a chance. While it is a decent (at best) screen, its low resolution is exacerbated by the fact that it uses a Pentile subpixel matrix. Maybe it's colors are accurate or whatever those tests claim, but subjectively, it isn't even close to being the best screen out there, not by a long shot. My money is on the iPhone 6. Similar resolution as the Alpha, but a million times sharper.

If you're colorblind, please disregard this thread. Rate this thread to express how you deem the color saturation and accuracy of the LG G6's display. A higher rating indicates that you think that color accuracy is very high and saturation is excellent.
Then, drop a comment if you have anything to add!
The LCD is fairly color accurate all considering. This screen is very close to what I achieve using a hardware color calibrate with my work machines. The reds are not too red (faux saturation) and the cooler tones show up as prominently.
It's just a shame I can't hook up a hardware calibrator to it to test it.
Solid color accuracy
I am coming from a OnePlus 3T, so when first firing up the G6 I was a little disappointed. I couldn't believe how much more vivid the AMOLED screen was compared to the LCD. Well, now that I have been using the G6 exclusively for the past two days, I am growing quite fond of this screen. The colors are quite accurate and precise, just not as vivid/saturated as what I was looking at for the past 6 months. Liking this phone more and more each day.
The screen color temperature is definitely on the cool side, certainly higher than 6500K.
It is not pleasant at first for me. I've been using Nexus 6P on sRGB mode for more than a year, and the color saturation on the G6 under default, out of the box settings is disheartening.
To somehow mitigate this, what I did was to enable ComfortView, set at Low Setting. It's far from perfect, but that's better than nothing.
How is this compared to the S8/+ ?

Click to collapse
From what I saw side by side compared to the S8+ at full brightness, I could see the whites having a more pinkish hue very slightly than the S8+. The S8+ having brighter highlights. Obviously, the S8+ also has deeper blacks, more saturated, and viewing angles are much better because of its AMOLED display. Other than that, the overall range of colours seemed fairly close between the G6 and S8+.
Not sure who will see this but I think the G6 LCD screen compared to an amoled like the one's on the oneplus 3/3t/5 and the s8/s8+ is just better in certain scenarios. There are some people who might be audiophile esque and want high fidelity and things like that. And there might be some people who like bass boosted beat headphones and other things like that which are not accurate at all but are enjoyable on a certain level. If you like big bass sound and you are that kind of person then you will like the amoled screen but I am personally not. I like knowing that what I see on my screen is what it is supposed to look like.
For instance the other day I was looking at a picture of the fifty shades of gray poster. It is supposed to be black and gray but it had a colored tint to it on the s8 compared to a g6 which looked as it should. All I am saying is that there are going to be times when the s8 because it pops colors so much will make what you see innacurate. And that might bother you or it might not. But it bothers me.
Exactly what Scape said. Tech people who know their stuff want accurate color reproduction and analytic sound. The wide mass wants flashy Colors and boomsound. Easy people rate phones by how saturated the phone looks. The more saturation = the better. This is complete BS for people who have knowledge about Electronics. Its like comparing people who buy a Classic car and put Chrome rims on it not caring for the paint because "CROME RIMZ M8". Where there are also people which buy a classic car, care to make it look as original as possible and know every part of their car.
The 2nd. Car may look boring to people, but its quality and worthwise extremely preferable. For example a natural Color reproduction can help when taking photos with the G6. If you take a photo on the Amoled Screen of a Galaxy, and then open it on your calibrated IPS, you will be flashed about how different it looks then on the phone. Thats not what you want.
Regarding the Bass... Well i like perfect color recreation but i hate neutral speakers or headphones, im quite a basshead but i still want a good clarity, deep stage and low noise.

Yeah, i kept my custom color setting enabled for a few weeks since the blue color looked way better. It is only when switching back to the default setting that i noticed how washed out the reds looked. I reverted back to the defaults.

True
I bought G6 after iP6S+ and I'm really disappointed from display over all. Blue is on G6 boosted as hell. At home I have calibrated displays and iPhone is much more closer. I can't watch photos (photographer) on G6 because of it. Even automatic brightness control is not ok for me. It's still dimmer than I want. LuxLite solved that but colors are terrible.

This is bad news for me, I find the G6 screen beautiful (I am under 7.0) and I do not like at all the rendering amoled screens, precisely because of the saturated colors..
I found on 7.0 that the flesh tones on netflix and terrarium tv were way washed out.looked like everyone never saw the sun lol Na just saying I think LG just corrected the saturation a little bit to not make things so washed out looking.The reds are a little darker also instead of a orangey yellow tint.And like before the greens were not as dark .kinda reminded me of a mint or pastel green.Now on Oreo it is a true green and red.
Is there any app or any online guides to correct the LG G6 color accuracy and get true neutral white balance?
I have s8 and G6. I hate Amoled with that compotish colors. White is not white. Ever with pink or blue or yellow. Amoled is like woman with silicon tits. Far from reality. For me LG and Sony make most better displays.
Does anyone use this? I did for a while. I found it very good at adjusting the blues making them a bit darker FB looks much better IMO after I adjusted it
Hello RXT Users,
I bought a new Realme XT (6GB,64GB, Pearl White) Mobile, which works like a beast.
But within a week, I accidently noticed that the true deep blacks of Amoled display actually kills the surrounding Grey colour pixels especially in videos (or moving frames).
When I using Instagram, Samsung just posted some photos. when I try to swipe one photo horizontally, I noticed that the gradient colours (White to black) are like vanished some time and and a bluish shade is appearing btw the blacks and whites.
Then I started comparing this with other LCD panel, which is not doing these weird things. I also did a side by side comparison btw Realme XT and other LCD display by playing a dark horror movie. The results came was not expected.
First things first, the picture quality, colours, contrast and viewing angles are awesome in Amoled display, But the grey coloured details which are nearer to the black pixels are missing, they are completely gone.
Example:
• Original frame in the movie - A dark room with cupboards and interior.
• Picture shown in LCD display - white blushed dark room with cupboards and interior.
• Picture shown in Realme XT - A Deep Dark Black room with no interiors no cupboards or even no walls.
I can't understand why the Amoled display takes more time when pixels changes from black to grey colours, may it's because of low refresh rate.
Can anyone please tell the display refresh rate of Realme XT and try the above tests to clarify that I am not the only one who got these weird thing. Thanks in advance.
Note: I am using Amoled display for the first time.
This is quite disturbing to know. I was planning on buying XT and returning my Poco armoured, as it has ghost touch issues and I don't need that much processor power for daily usage.
Also, with XT getting started on development I hope I won't miss Poco. But with the above-mentioned issue, I'm getting skeptical because my primary reason to get XT was AMOLED display. I don't want to get disappointed by it.
Although it doesn't has ambient display and dark mode yet but I hope it'll be there in future updates.
Sent from my POCO F1 using XDA Labs
After reading this post I checked my xt's display for the greys in dark scenes with my le 2 LCD display and I'm pretty satisfied. I was able to see most of the details of dark scenes that was visible on the other phone. Plus I found it's very vibrant as compared to the le 2 and brightness level is also much better.
