Bought brand new OEM Galaxy S4 LCD assembly from ETS. However, i've tried it with a few S4 motherboards, and with everyone the Samsung i9505 startup logo is purple. And it doesn't look right. Even though it's purple, there are specs of white around the edges of the text.
Plus, what's really confusing is that i bought this replacement LCD for a customer who's screen was playing up. The customer's screen would also startup with the purple i9505 logo, but then also display some gray garbled image, and then display correctly but with a haze, which would correct itself after a couple of minutes. The phone would also have problems playing videos and some other display issues.
Originally i thought the customer's phone had an LCD problem, but then i tried the replacement LCD and saw the same purple startup logo, and then settled on it being a display IC fault. So i assumed there was nothing wrong with the replacement LCD.
But now i've tried the LCD with 2 other motherboards, and get the same result (purple startup logo, not the other display issues).
So i believe the display IC is faulty, but it's strange that the same purple startup logo is occuring with the new LCD. Other than the purple logo, the LCD appears to work fine.
Has anyone else had a purple startup logo, either with an OEM replacement LCD, or their S4? Is this a defect that warrants return to the supplier (ETS)?
Hope this all makes sense...

Hmmm.. hard to say, as I never seen something like that here, at XDA... however, one user claimed such phenomenon, but not on new screen... see here, as the result of dropping the phone.
Well, first, I'd try this.
But, I'd expect no significant improvement, as from the description of a guy cited above, it seems to be likely that such may be caused by micro-crack on some circuit.

Thanks for the response, but I sent it back to the supplier and they sent me a replacement. All good.

Well I got a "refurb" 8525 from ATT and it was sweet. Until the screen stopped responding to touch. So I had ATT send me another(at my charge first). Well the second one arrived quite quickly but it has the obvious yellow(pee'd on) looking screen. Next to my other 8525 the difference it very obvious. To me anyway. My broke 8525 has white whites. Whereas my replacement one has a yellowish white. I'm kind of miffed about it. I think I'm going to call and have them replace it one more time and see what happens. If I get another yellowish screen I guess I'll have to deal with it. Also I notice the speaker on the replacement is "louder" but more "muffled". Strange. I used the same Black rom on both units so there shouldn't have been any differences software wise.
Anyone else experience this? I'm thinking that maybe my replacement had a cracked screen and they replaced the screen with a lesser quality one...?
Very interesting. Out of the blue, when I turned my phone on this afternoon I started seeing top to bottom vertical banding. I've noticed that it changes depending on what colors are on the screen, especially in the top/status bar. They are mostly white/gray, but there is a little blue and red.
The phone is only 8 days old, so I'm planning on bringing it back to Sprint on Monday morning. I'm quite sure it's a hardware issue, but I haven't seen anyone else posting about it with this device. I only wanted to see if anyone else had this experience so that I could decide whether it was a design defect that would cause me to reconsider my choice of this phone.
Peace.
have you drop the phone? coz mine develop a horizontal one on the top display .. drop from about 1 feet from the ground
fortunately for me, after i reboot it, the issue gone for good

No drops. Phone was in an OtterBox Defender.
Didn't go away after multiple reboots.
Brought it in to a Sprint store and they ordered me a replacement.
Glad I hadn't rooted it yet.
i notice these lines to, its more of a grid that i see, vertical and horizontal lines, i believe its supposed to make the phone more responsive to the touch of our fingers, making it react faster than other android phones...just an assumption

I had this happen after I had my screen replaced (cracked screen). Local repair guy replaced the screen, seemed to be working fine. I took it home and got these same vertical white streaks. Took it back to him, he found some kind of lose connector or board somewhere below the screen and had to apply some adhesive. I'm picking it up today to see if the issue is truly fixed.
Mine showed after i took the phone to capture images under direct sunlight

I have this exact issue, only difference is that the screen sometimes goes black. I noticed that when it does of I press the lower part of the screen it will display the white grid briefly then go black again. I have tried holding down the circuitry near the connector at the lower part of the screen down but to no avail. Please help.
I think I've experienced the same with my phone after a DIY display replacement. I put some electrical tape between the display connectors and the radio cable. Make sure that the tape is holding all the display connectors in place.
Hi,
Dropping my phone was the worst thing that could happen with my phone.
I found someone who would do the screen replacement and after nearly two months he finally returned the phone two me.
At first glance it seemed ok but closer inspection have shown me that:
- the panel used was JDI instead of LGD so a japanese panel instead of the 'original' LG
- serious screen bleed contouring the whole screen
- highlights on the screen, points in the screen where I can clearly see the backlight being brighter than everywhere else
- luminosity is lower than the original.
The last two points are very annoying. I compared my phone with a phone displayed in a shop and I see that the screen on the shop's phone is brighter that mine, even without adaptive brightness and @ 100% luminosity.
Could this be due to different panel manufacturer (JDI instead of LGD)?
The screen bleed could be due to the screen being badly glued but I am not sure...
But the bright speckels are annoying also. In bright areas this is very much noticable, a white picture shows two small areas brighter which indicates to me that the back of the panel has something behind that 'pushes', hard to explain.
Anybody had similar issues or had his screen repaired?
You can see my issues in the attached screenshots...

I don't think your issues is the panel type, i replaced mine and got a JDI from eBay. I don't notice any difference from my old one, which was not JDI. I would say you just got a poor screen. Not the fault of the installer either, i would try to get hold of the screen seller, or just accept the loss and replace it again.

I can agree that the panel type is not the culprit but the screen bleed is definitely the installers fault.
I am not very happy replacing it again as the total cost would mean that I could have bought a new phone for the same price...
My feeling is that the seller of the screen has delivered a used screen and damaged the silver back of the panel by removing it from the old device (the bright highlights could be from a prying tool used while recuperating the screen.). Too bad , lesson learned = do not drop the phone as the screen shatters very easily and when repairing, find a reliable repairsman...
Accept the loss seems to be the only option in this case...
Maybe I will have to disassemble/assemble the phone myself and do with with extra love and care and sense of detail....

Since the digitizer comes glued to the glass I'm more inclined to blame the screen/seller than the installer. But you know the saying... "If you want it done right...". All the best on getting it sorted and working properly.
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!

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.
So.. Just today ive been noticing the remnants of a game or video name being "left" "burnt" (if you will) into the right top to mid side down the ride side of my display.. Any ideas? Has anyone else experianced this? Trying to recreate it but its only doing it very fantly currently.. And barley noticable.. But after i had played my game for a little while earlier i could clearly make out parts of the game remnants on my display..
I get this too but it only shows up on grayish colors and it goes away after about an hour or so. Happens mainly with 2nd screen but it'll do it every now and then on the main one. Brightness seems to affect it's appearance more as well. It shows up more frequently for me when Brightness is @ 90 and up.
same here , i am getting the pixel burn as well. what can i do any suggestion?
I'm getting the same problem, called T-Mobile they're sending me a replacement unit to replace the replacement for the original that was bootlooping.
For all with the problem, I suggest getting LG to repair it since it should be covered under warranty. Also, just thought I'd add that LCD screens don't burn in, like their AMOLED counterparts. I believe you can describe this as ghosting, or just say the pixel is stuck on the same color if a customer service rep asks. I could be wrong, but this is what I've heard for most of my life. Hope that you guys solve your issues and return to a problem free experience!
Guys try a program called Pure Noise 2 and let it work overnight. I never had this issue with my Note 4 but even then I periodically ran the noise program. Let me know if it works!
Residual Image
I have this issue as well. From Google sleuthing I've discovered it is referred to as "Residual Image" and it is not a "burn in". It was said that the lcd tech used by LG has this "characteristic". It does self correct. And, most definitely appears most often with gray backgrounds. After seeing both of my parents s7 Edges AMOLED screen burn in issues, I feel we have the better tech comparatively. yay?
Screen Retention\Ghosting
Same problem.
Is covered under warranty?

This is pretty much the conclusion I've come to after researching for awhile
