Is there any way to correct the colours on the Defy display ? They look a little washed out, a little vibrance wouldn't do any harm. A screen calibration tool would be good, but I don't think that there is one compatible with Defy.
Maybe something could be done on kernel side ?
Any ideas ?
P.S: I'm coming from a Omnia7 that had SuperAMOLED, the colours were very vibrant.
Check this out. Defy has the same screen, and, actually it is very good color wise, almost perfect color reproduction.

I think most other manufacturers overdo colors in general, especially Samsung. I really don't like thei screens, too much color.
And to answer your question, no I don't think you can calibrate these screens so easily.
Would adjusting the brightness setting do the trick? Especially if you're in auto and there is something blocking the sensor.

Have had this phone for a few days and am adjusting to LCD again after a long stint with SAMOLED+.
The colors on the Optimus look a bit muted to me, and dark grays aren't quite as deep as I prefer them. No doubt I'm just used to OLED. Is there a way to calibrate/adjust the color or even the gamma level? I don't know of an app that does it. Some ROMs have this feature.
Also, anyone know what the color gamut on this LG is? I hope that it's not low color gamut like the iP4, but it doesn't appear to be (hard to say, different OS).
I'm the only one who wants to color calibrate his display?
Is there a script available similar to this for the Galaxy Nexus? http://forum.xda-developers.com/showthread.php?t=1521195
Even pentile matrix users want a color calibrated display!
I obviously can't speak for all users, but I've been completely happy with the color reproduction of the Nitro display. In fact, I'd say this is the best display I've ever used on a mobile phone. AMOLED's tend to be over saturated according to the experts whereas this screen scores really high in all tests of quality. Minus the HTC One X, we probably have the best display out there.
Out of the box, SAMOLED+ displays are horribly inaccurate and far too sharp, but after calibration (especially under 4.0+), colors can look quite accurate yet pleasing.
I'm not expecting this IPS display or any LCD to match OLED for black levels, but I believe that the Optimus' display, with some minor tweaking, can be better than it is right now. On LCDs, I prefer to turn up the backlight, turn down brightness, crank up contrast, and lower gamma: this creates very deep blacks and amazing contrast. Dark greys and minor details are slightly crushed, but this is a compromise that I'm willing to make.
Is there a script to lower the gamma level on the Optimus? I don't even need to do anything with the colors, though of course proper calibration would be nice too.
Excuse the n00bity, but could someone explain what the flashing the Perseus does as far as color calibration goes? It does say the color calibration is better than iPhone - so how does it work? Does it look more "natural" in natural mode? Would I notice much difference (barring resolution and brightness) when it comes to color reproduction compared to other LCD devices?

I don't understand nothing ...What do you mean?The screen is much better than iFail's
Flash perseus, and you get much true colors than saturated ones that comes with s-amoled. If you haven't noticed, there's a slight green-ish tint to the white, which you can get rid of. And obviously you can tweak the calibrations to set the screen to make adjustments that suits you. You'll lose the screen modes, though.
Lots of audio enhancements and stuff like that too. Really a must flash IMHO.

basically perseus rom comes with an app called 's tweaks.' under display settings within this app you can enable something called 'master sequence.' you can toggle it on and off instantly without rebooting. the effect of it is that you get more 'realistic' and natural colors and not the bright saturated colors you would get using amoled samsung phones normally.
i personally prefer the bright saturated colors but the only way you will know is by trying it out for yourself.
Did some comparisons between the Moto G5 plus and my old ASUS Zenfone 2. As soon as I started using it the colors seemed off, everything had this weird olive greenish hue and It didn't make any sense because launcher/homes seemed fine. But I'd browse a website, play pokemon go, or look at instagram and things were just washed out and dull while at the same time parts looked fine.
Finally found a test that explains what I was seeing and it's not good news. I was running the latest firmware with the volte fix. The app i used is called "DIsplay Tester" by "Brainntrapp" and open the test was "Banding, Contrast, Saturation" test. There are so many colors just missing on the G5 Plus the gradient looks horrible. The banding you see on the G5 plus was not visible in real life but the missing colors and hardness of the gradient was. Photos were taken with a Nikon D90 and Tamron 17-50 2.8.
The screen was driving me nuts so I didn't mess around with getting a replacement or sending to Moto to fix because I couldn't live with it if it didn't get resolved. I'll just have to keep looking/waiting for a replacement to my old zenfone.
Figured if any of you were having issues you could see if yours is similar, also curious to hear if you're _not_ having this issue as well which means it may make sense to buy once production issues are fixed.
I can't really tell any difference between Vibrant and Standard, but don't see any banding as in yours and think they look pretty decent imo.
The screen is on the less vibrant side than some others, but colors appear very accurate/realistic and the sharpness of detail is very good. My Moto X Pure screen is 1440p with more color depth but it has a yellowish tint to the whites in comparison. Coming from the Pure at first I thought the G5+ screen was going to be too bland, but after using it awhile I like its softer look which seems easier on the old eyes while still being very viewable.
I agree there's a really minimal difference between vibrant and standard. However, you took screenshots which will not show any issues as the actual data being sent is correct so we can't know if your screen does or doesn't have this issue. I had to take a picture of the screen with my DSLR and included my ASUS for comparison as a way to demonstrate the issue.
In the pictures I took, the hard breaks you see between the colors in the G5 are supposed to be smooth gradients and there is a ton of blue missing from the panel as well. This isn't just an issue of the screen being generally desaturated this is an uneven distribution of missing/desaturated colors. If it doesn't bother you that's certainly fine but it's very much an issue with the screen that should be addressed as it means that it is incapable of accurately reproducing colors even if the reproduction is pleasing to some. The banding I'm referring to is in the green section on my pictures and was not visible in real life and some form of artifact from taking the photo.
Sorry, I misread and thought you were referring to the banding as the main issue. I do see the more distinct color separation or breaks when looking at it directly in the app in either color mode. Just ran Display Tester on my Moto X Pure which shows the much more gradual blending (like on your ASUS) when looking at both phones side by side, although it should costing $150 more.
So it does indicate the G5+ lacks in color depth, something I noticed right away but which hasn't seemed like a minus after using it. The sharpness and wide viewing angles still seem like good quality, perhaps because it's IPS. But now I'm wondering if the KCAL features included in the latest extended stock kernel might help adjust things to look better.

That's part of why this confuses me so much. The sharpness and viewing angles are amazing for an IPS panel I'm not sure if IPS has anything to do with the colors (the ASUS is also IPS). I'd be very curious if KCAL helps as it seems like it should be able to, it could also be as simple as a bad color mode on the panel driver? I'd love to see a comparison from a custom rom to stock. I'm very split on thinking it's a software issue or it's a hardware issue. I don't have enough knowledge or experience to really do anything useful, but I'm hoping that providing the info gives others an ability/info to understand and look into it.
KCAL greatly improves the 'banding, contrast, saturation' result in Display Tester, which now looks as good as your ASUS or my MXPE once I found a good range of settings. Even on KCAL's initial settings the color gradients looked drastically better, so whatever was causing the lousy color depth definitely seems to be corrected by it as the screen looks excellent now.
I'm running on stock using the extended kernel btw. Maybe someone using a custom ROM can post on whether the colors are noticeably better than on stock and also test it in DT for comparison. Seems it'd be more of a driver or configuration error or bug than something hardware related, so maybe Lenovorola will be able to fix it with an update.

What we have to help with the washed-out screen is KCAL support available in both custom kernels (ElementalX and Extended Stock) on this forum. After installing either kernel you'll need to use either EX Kernel Manager app or Kernel Adiutor app (both at Playstore) to access the color control settings. I also found the Display Tester app mentioned above useful for checking how the settings I made looked. My screen looks terrific now.
I found that setting Saturation to 45 brings the best improvement, while setting Value to 135 brings another slight improvement.

That's indeed a very good setting. Thanks!
Saturation 50
Value 115
Contrast 140
Is what I've been using lately

I tried that and looks pretty good. Going to tweak contrast and see too. We should start a thread sharing tweaks
There is no way to fix this without root or Custom Kernel?
So if I'm getting it right I have to run kcal v1.2 on my moto g5 plus and from there I have access to color controls, is that correct?
Unfortunately, I have this same issue, although I didn't realize it, because my wife used the phone on the wifi to talk on Facebook so I ran out of time to return it.
What makes it worse is that it's the amazon-ads version so I can't even root it.
I put this phone right next to 3 other phones (with all LCD screens to be fair) and the difference is kinda shocking. The G5plus looks like it's been bleached, all the colors are faded, like I pulled some sliders to make it less vibrant and more black/white.
My wife didn't notice it, since she was using a basic phone until she got herself a new phone and told me, that "how come this looks more colorful?" That's when I took a better look at the G5plus.
After using it as my daily driver for a week, this phone got some serious color issues. Interestingly the pictures I took looked awful on this phone, but when I looked at the same pics (uploaded to google photos) on my PC, they look ok, not missing any colors.
Another issue I noticed. I turned off auto screen brightness OFF, because it just doesn't work.
I walk out to sunshine and the screen won't brighten and when I walked inside it won't darken so I ended up manually changing the brightness.
Here is the interesting (or rather annoying) part: When I turn the brightness up, it seems like it makes the whites more glowing, while the dark /black (let's say a shadow of a tree) just either stays too dark or turns more grey, instead of brighter. It's like the brightness control is controlling the exposure and contrast only.
Despite I see youtube videos talking about its 4K video capability, I think this phone makes terrible videos, especially how the camera applies too much contrasts and the HDR doesn't help it.
I also believe, that it's not all and every single device have this problem, because I'm sure I'd seen more complaints. It's just horrible quality control, and that's Lenovo for you.
I tried color tuning apps, but nothing seem to work. It probably requires a root but since it's an Amazon phone, it won't help it. So the phone works great as a phone, it just have an awful screen and a mediocre camera
This phone may have been enough in 2016 and 17 with these weaknesses as a budget, but seeing all the new budget Chinese phones coming out this year, I would not recommend this phone unless you can pick it up for $100 or less.
This phone is going into my drawer as soon as my new LG G6 arrives and the G5plus will be only used as a backup phone. There is no way I would keep using this as a daily driver unless I have no other choice.
Hello, I just bought an S20 + and instantly I have noticed that the image quality is a little strange, the letters especially on black backgrounds look like with a reddish outline not very noticeable but enough to bother me and some images in general are come as low quality. I came from using an A71 where everything looked correctly maybe that's why I notice the problem so much.
I was reading on forums where they say the S20 has various display issues, especially the ones made in Vietnam like mine. Others say that the reddish tone is due to the screen protector that comes pre applied. I would like to know if anyone else has noticed these details or if it is just a problem with the firmware that can be fixed later. Thank you. Sorry my bad English.
This may have something to do with display's subpixel layout and subpixel rendering, but the effect should be very subtle, not immediately apparent.
Tell us face-to-phone distance in centimeters when you start seeing the effect, display's settings such as brightness, resolution and refresh rate, where exactly are you seeing this (name of the app, dark mode on or off), font size, visible in darkness or in well lit environments as well?
Best thing to do, if possible, is to go to a local store that has S20+ on display, and compare, or if inside glass showcase, ask if they can turn it on and show it to you.
Also, that factory screen protector is known to be of not the highest quality.

Thanks for answer. I have managed to reduce the reddish effect by calibrating the screen because it was warm by default. The blurring effect of the letters decreases a bit when using it in 1440p..... but I have noticed that it may be a problem with my eyes because the same effect occurs when I look closely at my PC screen (10 centimeters), black text with reddish tint. I will try to go to a local store and compare with another s20+. As I mentioned it's little noticeable, maybe I have very demanding eyes.
I wont remove the factory protector for now, although I know the screen would look better without it.
My complaint about low quality monitors at work and with phones has been resolved with visit at the optician, and i dont mean to offend you here but seriously since i have glasses screen looks finally sharp again!
