BE WARY! of the devil of the knock off lcd assemblies!!!

Hey fellas ;
I just wanted you to know that i cracked my screen and half of my digitizer was not functional.
I used "wm size 768x800" on the terminal to be able to use the screen until i got my replacement lcd assembly. (Frame included.)
Yesterday i got it. I wish i hadn't.
I first realized that the screen is significantly more blue than the original. I thought maybe when i mount it it would go away (It was a long shot.)
I mounted it and it was ready to go , then i received a phone call and i couldn't end it because the screen wouldn't turn on. I immediately knew that there was something wrong with the proximity sensor. i plugged it out and tested it , it works fine but the problem is with the slot. It's significantly higher than it should be , causing a gap between the screen and the proximity sensor. Proximity sensor outputs it as an object in proximity and turns the screen off , never to turn on again unless the other side ends the call. I solved that with power button ends call feature.
Then i got a notification from facebook and i realized there is a circle around the notification led , that circle should have been covered with an optical filter which filters and focuses light. Without that filter you won't be able to get side colors such as purple because there are two sides to that LED which light up differently. One side lights up as blue , the other as red then these lights go through the filter at the same time , they are combined to give you purple.
I harvested my broken screen's filter and cut it so that it fits the circular spot in the frame. The actual shape is a rectangle because it is put between the frame and the digitizer.
So , i got it to a tolerable state then i went to get some cigs. I got a call , talked then when i slid the phone in my pocket , the digitizer fell off and ripped the flex cable.
Then i got home , flamed the seller so hard (politely) , he probably caught fire while reading it , so he accepted paid back my money , didn't even ask for a return shipping , he said to keep it.
I went ahead and bought the original one from a friend who works at LG , and all's well.
I mean not even a hiccup , it's great.
I'm opening this thread so you don't need to live through the same nightmare i did.
First thing to check is the digitizer's IC on the flex cable , it should be wrapped with aluminum foil , if it's not , it's a fake.
LG doesn'T sell the assembly without the frame so those that are without frame , they're fake.
There shouldn't be a circular spot around the notification LED , if there is , it's fake or without frame , still fake.
The screen should be pitch black on medium light , if it's bluer , it's a fake.
If the screen bulges out from the frame so much that it's annoying , it's a fake.
If the proximity sensor isn't working , it's probably a fake as well. It doesn't have anything to do with the purple filter , it does with the gap.
If the lcd does that weird thing when you tap on the screen , it's a fake. (That weird thing is , colors and pixels getting all mixed up like there is some kind of a liquid inside the monitor (there is). It happens because the glass is more flexible than it should be , thus it's not gorilla glass.
I mean i wouldn't mind a nice clone with just the blue of the screen , but this is intolerable.
It was 40 dollars on ebay , should have figured it was a fake from the price tag.
I hope i spared you a nightmare.
Edit : So , i still had the knockoff screen lying around , thought i would buy a broken nexus 4 for 100$. I got it , installed the screen , fixed the digitizer flex cable , everything was fine but out of the blue , the screen started appearing weird , there were lines on the screen and the resolution somehow dropped to like 640x480 , i can see the pixels clearly now , they got bigger. I don't know how or why. Anyways don't buy knockoffs because they're cheap. A week tops , then you'll need to get a new one. OEM FTW!

I have also been bit by knockoff screens for a few phones. The knockoffs just are not held to the same specs I guess. My latest was a new screen for my daughters G2. Cheap price and fast shipping, but as the phone heats up from use it gets ghosting and white lines......hard lesson learned I guess.

Back when the digitizers were separate from the lcds and gorilla glass wasn't so popular , i used to order knock off digitizers from ebay for me or my friends then i would fix their phones with that stuff , it always worked but i myself glued them to the frame. I had never tried knockoff LCDs because i knew better.
FFS , i live in Turkey and nobody and i mean nobody has ever heard of "3m". So i usually need to order it from U.S. , which takes about a month to get here and i was out of double-sided tape.
Genuine assemblies come from European countries or U.S. but almost never from China , which is a shame because nobody else offers free shipping. 10 $ for the glass + 30 $ for the shipping. That's just unfair.

[Q] Z3 Compact Display Issues

Anyone having the same issue as me? Cause it seems that My set that I just gotten today (Green color) has the usual yellow tint that is slightly visible, but not as serious as the z2. Can be seen when placed side by side the retail demos of z3 and z3c, it seemed like there may be different manufacturers for the display as well. It's not cool white anymore.

Yes there are different manufacturer, mine also has less white whites than another unit. But overall mine has better contrast so... As for the yellow screen it is not necessarily a bad calibration as displays whites are usually too blue in comparison to daylight "real white".

Ahhh I know right. The color actually looks decent, due to it being slightly yellow, but mine has slightly more yellow, nearing the z2 one. So I'm going to go down service center to check tomorrow.

How is white balance for you ?

Hello there,
I bought my z3c off amazon, noticed after a while the screen got quite pinky when at lowest brightness.
So i got a replacement. Just before I send back the pinky one, here is a comparison between both screen (left : pink & old phone, right : yellower new one). The picture was taken at custom 5000K with a nikon reflex, then color balanced to 6500K in lightroom.
not sure what to think about this pretty big white balance difference between only 2 random devices.
Any insight is welcome.
Cheers.

Do you have any of the color enhancement options enabled (X-Reality or Vivid)?
I have both turned off and find the phone's white balance is actually better than most people seem to be experiencing.

I do notice that some Z3 Compact displays look different. For example, the ones displayed at a Sony Kiosk here look different (more bluish) than mine.

I think that Z3 Compact is not the best screen I've seen. I've just sold a Galaxy S5 and it was a better screen.
What I see in my Z3c is that the screen is not very uniform, specially in low bright modes.
Despite all, the screen is good. I hope that Z4c would be a bit better.

Tried with xreality things on and off. doesn't change a thing.
Oh and the replacement device i got from amazon, it has lightbleed this time
Seriously, poor quality control from Sony. sending them both back. tired of this $h1t :/

Note 4 - Annoying quirks

When I first got a N910F, I immediately noticed the top right corner of the screen was lifting up, which seemed like the adhesive on that side was not sticking. The top left corner had a yellowish tint, and the camera was faulty, becuase when I'm taking a video, the video jumps when I pan to the right. So I returned it and got a N910C as a replacement. This particular unit, also had lifting, but it is on the bottom right. When I put pressure on it, it sticks right back in, but after a few minutes, it lifts up again. What makes it worse is there is light bleed on that corner when the back button lights up. Under direct sunlight, and when the screen is off, I can see "brushed effect" under the main screen (the whole viewing screen) at a certain angle.
I seem to be very lucky with samsung, that I get defective units no matter what I buy. Or is samsung lacking quality control?
================================
These are some of the problems I encountered with each device as far as I can remember:
1. S3 i9300 = I had to go through 5 units, reasons are the Sudden Death Syndrome, and the Ink blotch effect. Then after three moths, my lovely 3-year old daughter poured milk on it which damaged the screen, it is now prepped and tested and ready for a new screen, just waiting for replacement screens to go lower...
2. Note 2 N7100 = again Sudden Death Syndrome, and Ink blotch effect (I had to go through 3 units till I got a good one)
Note 2 N7105 = Ink blotch effect and LTE was erratic (first unit returned, and good second unit sold)
3. Note 3 (N9005) - pinkish tint on lower half of screen
Note 3 (N900T) - first and only unit I had, had a faulty ear piece. When the phone was on, even I wasn't doing anything, I can hear a 56k modem-like noise coming from it. Tmobile people confirmed this.
4. S4 (i9505) - first unit had very strong pink tint on lower 1/4 of screen, second unit had a small piece of dirt on the center of screen, third unit is awesome, but I sold it on swappa because I got a Tmobile (M919) version which I am still using today.
5. Galaxy Tab S 8.4 = the bezel next to the sd card slot came apart out of the box.
6. Galaxy Tab Pro 8.4 = Buzzing sound coming from the screen (not speaker), I still have this unit now, look at my signature to see video.
7. Note 4 (N910F) = yellow tint of top left corner, faulty camera
Note 4 (N910C) = lifting bottom right corner, light bleed on same side, brushed effect under viewing screen, when the screen is off and under direct sunlight.

Could be either of them, neither of them or both.
In any case, I'd definitely return the second unit ASAP if I were you.

Or you buy from a store always who has B grade items or refurbished that it sells as new

Nope, I almost always never buy second hand. This is why I buy from amazon, or Fulfilled by amazon, or from best buy, I don't mind paying a few extra $, as long as there is no problem in returning a faulty item.

the only "issue" I've had on mine so far(not counting bad design decisions, like a protruding front-facing wake button for "convenient" pocket-dialing) is the incomplete application of the oleophobic coating.
there are 2 small spots with no coating, so there will be 2 small smudges if i hold my phone in direct sunlight without using a cleaning cloth first.
it's still better than having the entire screen covered in smudges though.

Mate 20 Pro 8GB/256GB Question UK

Hi All,
I am about to take delivery (Tomorrow) of an imported 8GB/256GB Sim free Mate 20 Pro twilight in the UK.
Is there anything I should be wary of?
I am normally (dare I say it) an Apple fan boy ... There I said it! (Current phone iPhone X)
I have gone for this option for 3 reasons.
1. The added ram and storage space over the 6GB/128GB model.
2. It will good to have the dual SIM functionality, I normally carry around an iPhone X (Personal phone) and an iPhone 6 (Work phone), I would like to do away with 2 phones and just use the one.
3. The camera setup seems fantastic, I do a lot of photography both privately and while at work.
I see a lot of complaints about green bleeding on the screen, is this still a problem on the 8GB/256GB model? If so, what can I check for once it is delivered, ideally for a fast return of it if need be.
I have ordered from an eBay seller who advertises that the packaging is opened and a UK charger is supplied and that the 1 year warranty is with them. They have openly admitted that they are imported from Hongkong and Singapore.
I cannot find another UK seller selling this particular model, the only one selling with the dual sim function is only the 6GB/128GB version on Three with a 24 month contract, which I am not interested in.
Thanks all.

You can download Device Info HW from the play store to see what type of screen you have. BOE vs LG. LG are much more common to hvae the green screen issue develop, but it's not exclusive. And not all LG screen are bad. You can also check the serial number. In the middle will be an 18, letter and another 2 digit number. This stands for 2018, then a - october or b november and the 2 digit date of manufacture. Later dates seem to have a better chance of no defect.
Then download Mate 20 Pro screen tester also from the play store. I think it's just named screen tester. You can then lower the brightness level and go to a dim area. This will show any defect if it exists. Also using performance mode, and using the provided fast charger seemed to develop the problem, or it may have just been a coincidence. I can't say for sure. Good luck! hope you get a good one.

Thanks for the info,
I hope a get a good one too! It's going to be a hard transition from iOS to Huawei, I used to detest this brand in its early days, but WOW!! they have come so far, I am very impressed.
Slightly off topic, is there an easy way to move all my iCloud stored photos and videos etc across to the Huawei?

Does the twilight model have more chance of green screen??

I hope not!

You should have a good one. Everything indicates you have a good production date and BOE screen.

Still going strong! :good:

I have a 128GB UK version I purchased at launch with an LG display and planned to upgrade to a 256GB international model with a BOE display. I ended up returning the 256GB version because to me the LG display seemed way superior.
At least some of the hysteria generated on XDA about the defective LG displays was nonsense.
It is normal for a folded OLED display to have screen bleed at the edges and it is also normal for a folded OLED display to show lighter around the edges when doing the screen uniformity test that purportedly showed that the displays were defective.
People were making comparisons between the standard OLED displays on Samsung phones and the folded OLED display on the M20P and since the results were different that was supposed to prove the LG displays were defective.
On top of that easily 70% of the initial reports of defective screens on the XDA Gluegate threads came from new XDA accounts that appear to have been opened specifically to report defective displays.
The BOE displays are much less bright than the LG displays at every illumination level including 1 which is why people don't see the scary light bleed eminating from the display edges.
That difference is very obvious if you compare both displays side by side.
The LG display also has much more vibrant colors and way better contrast.

Hi,
Thanks but I totally disagree regarding the screen quality.
After mine arrived I went into a Three shop who let me play around with a 6gb/128gb and side by side my BOE screen vs the LG screen was better. Also the brightness levels are either the same or if anything the BOE screen was slightly brighter.
The only bleed I can see on mine is 2 vertical lines right on the bend and this moves depending how I look at it, indicating that as you rightly say, it isn't screen bleed. The phones with screen bleed (Including the one in the store) was very very obvious and filled nearly the whole screen. Staff claim it is to do with the lights on the shop, but clearly that isn't the case.

You're in the minority. I had the LG and the screen was awful Truly awful. Green which is visible on all LG screens to some degree ruined the screen even at 50% brightness.
This is just your attempt at feeling better for having an LG screen.
My BOE is perfect and better quality in every way than my 6 previous LG replacements, which all had the "green bleed" not "off angle discolouration". Don't try to make out we are all confused, it's you who's confused and spreading nonsense.
Huawei confirmed to EE that the LG screens are defective which is why EE replaced mine 7 times until I got a BOE
BOE is just as bright. Just as much contrast. Just as sharp. Not faulty.
This account has been open a long time.
Next try?

My BOE replacement is pretty good also. Brightness and clarity is great. No dead pixels and no uniformity issues even with screen tester apps.
The LG screen was defective that I had. And many others have had. Not all LG screen in phones are defective, just the implementation in the mate 20 pro's for many people.
I think the edge bleeding is not necessarily normal, but rather a function of an inferior polarizer. The same reason LG and BOE are slightly more off tint when viewed from an angle. That same angle is produced by sending the screen. I still believe Samsung makes the best screens.
I also noticed that the BOE screen has some GHOSTING. If you have a BLACK background and scroll up/down with white text or windows. The white will momentarily be grey/purple lagged until the pixels catch up. But isn't something that will show up with a grey background, I think this is because the on/off function of the pixels is slower than other transitions. NOT a defect, just an observation. Haven't tested on a Samsung or LG screen. Just noticed while evaluating the BOE.
*Edit* seems it's black/grey that shows it.
Just found with a quick search, one that shows the purple lag.
https://www.reddit.com/r/GalaxyS6/comments/34t923/is_your_screen_defective_test_for_yourself_by/
Just scroll.
*Edit #2* just tested on my wife's Note 9 and there is just a hairline lag of purple that resolves quicker. Instead of half the grey square.
*Edit #3* just created another thread to discuss the ghosting separately.

This is an inaccurate statement, not all LG screens are affected.
My M20P was preordered before the October launch from O2 UK (so presumably a relatively early model) and I have no issues with any visible green at all at any brightness setting.

"green which is visible on all LG screens to some degree". Nope, not visible at all on mine, which has an LG screen. I've seen examples of the green issue, and mine is uniform black across the screen.
Have a friend who had a BOE screen on his from EE, and the two screens are unnervingly similar. Nobody would look at images on both and state that one is better than the other.
So care to try again?
