Purchased a C9O yesterday. Out of the box I immediately noticed the screen's low contrast in comparison to my Galaxy S2. It doesn't produce a deep black and the blue looks kinda purple-ish. Is this the same screen washout problem that's been so often talked about? And is there a fix to this issue (if it's even an issue) or did I get a defect? Or is it simply because I am too accustomed to GS2's overly-saturated colors?

galaxy s2 is very over saturated.
So make a pictures of the screen from a few angles and post them here.
Also this lcd can never be as black as your galaxy s2 display since it's a lcd instead of a amoled.
I can't get an accurate representation of the colors as these shots do look more saturated than viewing them from the actual screen.
Looks fine here, you can try to disable nvidia prism which is always a good thing (more battery comsumption but no buggy washout stuff).
But I tihnk it's just fine since it looks identical to my display, I also got a C90 after exchangeing my version from a older batch(screen lift)
Thanks. I agree those shots do look fine on a PC monitor. I guess the best way is to compare it with a store floor demo unit.
Would the Nvidia Prism fix require rooting of the device?
i think it looks fine when comparing my n7 to my e4gt it makes me realize how oversturated the epic touches display is. My tablet to me looks more correct color wise than my phone
I got a CLN replacement yesterday due to a defective display. It has a blue sticker "NB 05/14" meaning it was refurbished in May 2014. When I compared the replacement with my old phone, I noticed that a camera lens on my old phone is bright purple under a fluorescent room light while the one on the replacement phone is very dark purple.
Has Samsung started using a new camera module? Pics taken indoor by the replacement phone look darker but this is just my subjective impression.
Both phones were originally manufactured in April 2014, according to the stickers in the battery compartment.
The phone was not refurbished in May. That phone is a brand new phone.
It takes about 60-90 days to turn around a refurb phone.
They don't exist yet.
Yes, there is a green "core' and a purple "core", just like in the S4. There is absolutely no difference in the two as far as the images the produce. NONE. In the S4, if you replaced your camera, you had to make sure you got the exact same core. It could turn into a real pain in the arse.
Hi everyone, this is my first post in the xda-developers forum!
I dropped my S4 yesterday and a few hours later when I wanted to take a picture with the camera I noticed this horizontal line that goes across the screen (it even casts a shadow underneath the line). At first I thought I might've cracked the camera lens but I shined the camera under a light at all different angles and I can't see any crack. Can someonw help me on this so that I can determine whether I just need to clean the sensor or buy a complete camera replacement?
Try a different camera app. If it's the same then it might be the camera.
That doesn't look like a crack though. Even so, it still might be something case by the impact.

it's definitely inside since you dropped as you said.
go to your nearest samsung customer service. :good:
I've searched around and there's a short mention here or there, and I'm not sure if I should exchange my new S7 because it's actually quite an annoying problem that I've not noticed on my S6 or Nexus phones before this S7.
When I take a photo with the camera facing a bright light source, eg the sun or a bright light at night, there is a blue spot that appears in the picture. I know it's a limitation of modern smartphone cameras, and it's likely a lens refraction or reflection, but it really does take away from the photo if I'm taking one of a beautiful sunset or even a cityscape at night. LIke I said, it's the first time I've noticed this in any of my cellphone cameras. I've tested similar exposure in my friends' S5 and they have the spot too. Even my backup windows phone has this.
Do ALL cameras have this? Are there any S7 owners here who don't have this problem? If there are S7s without this problem, then I'm ok with exchanging the phone for a new one hoping for one without this. I'ts kinda a buzz kill for me on such a fantastic phone otherwise.

I have the same problem with my phone. When I take a pic of candles, there is also some kind of purple halo around the flame. I read somewhere that it is because of the lack of IR filter on the lens.
I agree with the fact that this is really annoying for a phone of that price
first problem is lense flare, it depends on optics design and is normal!
second issue (purple halo) is ir radiation not properly filtered, due to probably lacking IR filter.
this is an issue long present in mobile cam history, although there are and were mobiles with proper filtering cam modules existing...

Thanks guys, as expected, i figured it is a 'normal' thing, but it still drives me nuts. I'm still hoping to hear from more people, since misery loves company in the event that some actually say they don't have this, i might exchange my phone for another to try my luck.
I thought I was the only one me too
Hi guys,
Anyone else notice any uneven screen backlighting? I read forums on the v20, and when reading back text on white background - while scrolling down to read more text I notice dark shades on the screen. I downloaded screen test and lo and behold...dark patch on my screen! I then sent it back to LG and assured me that they replaced the screen module and tested it and all 'voltage' was normal - BUT, dark shades were still present albeit in a different spot!
Can someone here please confirm if this is a normal thing for LG screen as I realise it is LCD backlit and not OLED hence a few bleeding / inconsistency of backlight would be present. Even though I have never experienced this on ANY of my HTC's which were all LCD screens.
cheers guys! sorry for the long post!
Yes, i have it too! H910 variant. Two dark/dim spots that run horizontal from edge to edge. Can be more noticeable/annoying in landscape view than portrait actually.
Exchanged one brand new H910 for another. Same problem. Both manufactured 12/16. Havent had this on any other LG Ive owned (RS988 G5, D850 G3, P930 Nitro HD) or Moto for that matter. Pretty bummed to have this in an $830 USD device.
Edit...seems like the issue can be excaberated by different viewing angles. Also, totally anecdotal, but i looked at my display at a stoplight (wearing polarized shades) and i noticed the screen looked unaffected by the shades compared to other LCDs (cars TFT nav screen, an eIPS tablet, etc) that i have in the car. Wonder if what we are seeing is some type of side effect from a polarizing filter, or maybe lack of, used with this display/panel?
Or, maybe these things are edge-lit and LG used an uneven arrangement of emitters. Not really sure.
Good call...I do think it may be the backlight being edge lit! which could only mean (maybe) the backlight has failed at some spots or LG engineers mis-formulated where to put the lighting. it is very sad to hear that this may not be an isolated problem.
I did however sent it back for repair and the technician advice of a NEW LCD module/screen fitted. was sent back to me the same day!! WOW! BUT...same problem but it a different spot.
If this keeps going I may have to consider a new device altogether!
Then im starting to hear crackling on both earpiece and speakers....but thats a different thread!
arrgg...
I began to notice this on my v20 that I bought at the end of December, at first I thought it was just viewing angle or I messed up the screen. However my mom just got a v20 and hers' has the exact same problem in nearly the same spot. I should add that my phone is an LS997 that is completely stock. Also @D0NZ which screen test application did you use to see the problem better?
I used an app called full screen test...its free and simple. I then took a photo of it with my old htc m8 then sent it to lg for review.
The V10s have this as well. Something to do with the backlight and 2nd screen. Kind of got used to it on my V10. Was hoping that would have been addressed with the build of the V20.

But I still have that unwanted effect even if the second screen is off?

I think so. On the V10 it was really noticeable when the main screen went into immersive mode and the 2nd screen went off.

this to me is a deal breaker! I read a lot on my phone, tis why I got a large screen! If this is the 'norm' for a flagship...
I pretty much think its unacceptable. They produce their own screens and cant get a flagship right? hmm...which phone to replace it with now that is available locally (for me that is down under)
So here are some pics I sent LG originally!

Looking at your grey screen, those bands/dim areas are in the exact same locations on my device (and my prior V20)! It must be inherent to this panel. You said the bands/dim locations changed after LG swapped screens/devices for you though?
Either way, it is a bummer. I'm still undecided if I should return mine as well, or just live with it. Almost every recent device has some quirk to live with it seems. I recently traded a Samsung Galaxy S7 that had a beautiful AMOLED display, but the device picked up scratches (on the display *and* body) like I've never seen before. I even took a look over at the dark side (Apple), and they seem to be catching flak for overheating and camera problems in some iPhone 7 devices. Sigh.
I have it on one corner pretty bad, is this because of the IPS screen and how the frame of the phone is pressing on it?

I think its to do with backlight distribution tbh. Ive had a number of HTC's and NONE of them had backlight distribution issues. Im now wondering IF a 3rd party screen module would be better than the original LG produced? OR...if this is an isolated issue only on some devices. My device was manufactured Nov 2016. Maybe a later produced model has better screens? Anyone with a newer produced V20 care to share?
I think its the placement of the 2nd screen backlight. Ill try to find the thread. Someone with a V10 explained it last year.

Here is the post I remember from the V10 forums that seem to make the most sense regarding backlight being uneven.
https://forum.xda-developers.com/showpost.php?p=64236798&postcount=45
Both my replacement V20 and original V20 have uneven screen backlighting (at least the replacement has a better back cover mechanism). There is a dark spot in the middle of the status bar on white (or lighter) screens. What is weirder is that it is the exact same pattern and location as the first one. It is present in both stock and LOS. I suppose I'll just wait around a year and warranty it out then because I just want to start using the phone. I included an image for people that were curious how it looked.

I think I can live with that...as in...the dim sections are on the edge of the screen. Mine was in the middle of the screen which i cannot stand!
I have sent the replaced screen NOT to LG but to the place where I bought it.
They said that the repairer that LG told me to send it to was the last on their system as 'reliable'. The store said that they will deal with the repairer and LG. I kind of hope the worst happens and they just offer me a refund or a total replacement - but I doubt that would happen!
UPDATE: so i sent it back to jb hifi, on the report, they can replicate the issue. On the repairers report - they couldnt
SO i get it back with all the 'test' that they have done on it being to manufacturer's specs.
Which i think now...was never good to begin with
Too bad i cant unsee what i can see...sux...I wonder if AMOLEDs have these issues? Anyone care to elaborate?
I have this issue with my LG V20 -- only when viewing photos
I have this issue with my LG V20 -- only when viewing photos - see photos -- screen has two long bright lines.
See attached photos - lines are not on the photos themselves --it is just in the backlighting -- and the lines are not there when viewing websites or if testing the screen with an test app. Please cut ans paste links to see photos - remove blank area after http -- I can't post links till I have 10 posts on this site - if any kind poster could repost so others can see them that would be great!

...and these lines stay the same even when you enlarge the photo...

I have the same issue below secondary screen. Only noticeable on white background. Doesn't ruin reading books, it's there, but minor. I have dual sim variant. I'd be very upset if I paid launching price. All those things you only find out when you get the device.
