Hi !
I changed the display of the phone and the quality of it is not the same as the original (I had tianma)
I would like to know if there is option to calibrate the colors of the display, since they come very saturated and colors with little brightness or very dark
Thank you very much !

Had my s6e a week now and right from the start I've noticed an issue with the screen colours on full brightness.
When in bright light something happens that makes all the colours look washed out and slightly pink. I've never noticed this on my previous galaxy devices and it's really dissapointing
It seems to be related to the auto brightness glitch as it does this whether auto brightness is switched on or not. When in bright sunlight it switches into a mode where all the colours look faded and horrible. When I cover the front camera area or turn the brightness down it switches back to normal.
I've tried changing from adaptive to cinema mode etc and it seems to make no difference.
Has anyone else noticed the change in colours or have I just got a dud?
Sounds like the extreme brightness mode Samsung implemented on the Note 4. If so, that's how it's supposed to look in direct sunlight to make it easier to see.

Could be, looks awful tho :/
It does. I think the idea was to optimize contrast to make the screen visible at the expense of accuracy and saturation.
I'm having the same problem with my S7 Edge. Had it a week and then the colors just started to wash out on everything. All themes, all screens. Nothing fixes it. I hold it next to my S6 Edge with the same theme and the difference in colors is drastic. It looks terrible.
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.
I've noticed that when I watch youtube videos the people's skin looks a little bit yellowish and in general I don't like in general that the yellow seems a little bit off .How do you have your own color balance?
There is no best when it comes to colors, you can change the colors in the display setting to what ever you like.

Yeah skins color looks better with amoled photo mode too bad reds are a little bit washed out there
I just set it to Adaptive Display.
Hi guys
Can someone help me out understand something? When I bought the pace I really was not aware that it had such a low resolution when the watch was not active. I know it uses a transreflective LCD.
I understand that amoled screens waste more battery for lighter colors because black does not turn on any pixels.
LCDs on the other hand waste more battery regardless of color because it is the backlight that consumes battery right?
What about this transreflective LCD? I don't understand why the watch uses an 8 bit color pallet on the lockscreen and why does this save battery? Shouldn't the backlight be the only thing that consumes more battery? If it is just displaying and image (whether it is high or low resolution), shouldn't the battery consumption be the same for both?
Can someone clarify this for me? I tried searching but could not find anything..
Transflective mode reflects ambient light without using the back light hence the name.

I know that, but that's not what I asked. On traditional LCDs it is the backlight that consumes battery regardless of the resolution correct? On transflective screens, whether the backlight is active or not, why does the watch switch to low resolution on lockscreen and why does that affect battery? Because on traditional LCDs the resolution displayed does not affect battery right?
I don't think it switches to low resolution (otherwise small text would become unreadable which clearly is not the case) . It's just colors looking washed out because now it's only reflecting light.

I don't know it it switches to low resolution but from what i read it changes to an 8-bit color pallet, that is why it looks "low quality". What I wanted to know is why does that save battery since traditional LCDs don't have this issue..
This interested me as well and I found out it uses a MiP (memory-in-pixel) transflective LCD display (LPM013M091A). I haven't done much research on how exactly it saves power between those two modes but basically it's a memory limitation in a display itself so it switches between 8 or 262k color palette. As I understand it's not 8-bit color but actually just 8 colors in low power so that's why it only looks like low resolution.

I think it just uses the 8 color mode to improve contrast and be more readable in low light as the background light is off...
I don't think so. This is just how MiP displays work. They save power similarly to e-paper displays like the ones used in Pebble watches.
According to specifications in MiP mode (8 colors) the consumption is 0.8mW and in Normal Driving mode (262k colors) 9mW for still image and 13mW for moving image and backlight is unrelated and separate from display modes and contrast is the same but as I understand in MiP mode it can only display the maximum intensity pixel colors so it may look sometimes (depending on a watchface and ambient light) that contrast only seems better.
There are also MiP only mode displays as well. The one used in this watch is a hybrid type and it's just a hardware limitation in a display itself for these low power consumption LCDs.
Also maybe it's good to keep in mind that these also suffer from burn-ins if the same image is displayed for prolonged time so it might be prudent to change watchfaces from time to time.

Great info, thanks. But why 8 colors mode would use less power than 262k colors if it's the same resolution? Could you please link to the source of the power consumption in both color modes? TIA
EDIT: I've found this: http://www.j-display.com/product/pdf/Datasheet/6LPM013M091A_specification_ver03.pdf
So it seems that they are two completely different modes: MiP with 8 colors and transflective with 262k colors.
Yea, that's the display technical specifications. This is where I got the power consumption modes:

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.

Thats how amoled works.. Not problem phone.. Amoled screens are like that..
