Hallo,
I am a lucky owner of this fabolous smartphone but, unfortunately, I have a problem. Suddenly on my phone's display appeared a blue halo. It is something that it is not visible on a black background, but only on bright colours. Furthermore, it is localised to a specific portion of the display.
Now I don't know what went wrong with my omnia. The only explanation is that maybe I should not have used my mobile phone case because it has magnetic clips. But, as far as I know the LCD displays are not subject to magnetisation problems. In addition, I am sure that it is not a burned pixel problem, as I have already this problem. But in this case is not something missing...the pixel are there, but an a small portion of the screen that blue halo remain.
Can I do something before taking it to assistance center?
I am very happy with my Touch Pro. In fact, I bought 2. Now I have very many HTC Devices, however, both Touch Pros now show a very strange
behaviour.
I get some ghosting on the screen, which means, if I use solid colour
backgrounds, they previous graphic is partially visible.
Best example is the volume control. I get very strong distortions against the solid background.
Anyone else has this problem?
I also noticed that the mounting points on the edge of the screen, causes
a slight distortion close to ever corner of the screen...
never had this before.
I have the same issue. I've heard that this issue is programmatic not physical lcd burn. Usually a restart helps. Try

Yes, soft reset helps. But i find the location of these distortions really strange.
i get them around the LCD mounting points.
Indeed it is strange and looks really like a physical damage but I think it has something to do with the software (BIOS or whatever is on that position in pda) link to the screen power management. I have this kind of distortion once per week and often it also goes away itself. Actually it almost doesn't disturb me. Ii yours very strong?
This is interesting. I always look over my LCD displays in laptops very carefully for defects. Sometimes corners are pinched and produce dark areas. Sometimes the inverter is bad and gives bad illumination.
My Raphael's screen seems pretty decent so far, even if I look at its edges from extreme angles I don't see much of a problem.
Can you post pictures or youtube? I am curious to know what you are seeing.
On my almost 3 years old I had "oily stain" - obviously from wearing in pocket of my jeans. Pressure on display causes this problem. I dismantled phone and by aplying pressure on corners get rid of stain(done this once, it help for some time). But after powering up the phone, display was dark and with some strange colors(purple, pink...). I think I fu*ked up some of the flex cables with display signal or display itself, display doesnt look cracked and I am convinced that its not issue of backlight. Question is: Did someone saw this problem? Do you think that buying a new display from eBay(~$20) worth it? I am going to buy HD2(Leo) soon.. I tried to take photo but my camera cannot take that dark picture...
it seems display is damaged i took of whole display unit. Gonna buy new LCD sell it on ebay and buy HD2
Have the same problem on my touch pro after changing the screen. Dark display with some colored stripes that changes after i press some buttons or play a little with the touchscreen. I've tried to reconnect everything, play a little with the flex cables applying coductive tape etc. but no change. The LCD seems fine.
I have created threads regarding my problem at differrent forums but noone seem to know the cause or a solution.
Your problems are probably caused by a defective of flex.
I am fixing my broken Atrix 2's screen. The touchscreen digitizer and LCD were both cracked. I purchased OEM replacments and the touchscreen works great but I am having display problems with the LCD.
The LCD I received doesn't seem to have the same pixel density or color gamut. It also flickers a lot and then goes dead after having to change what is on the display, ie watching a video or switching screens fast.
When I hook up the HDMI cable, the output to my tv doesn't have the same problem as you can see from the video in the link. I have some other videos that I can upload if needed.
The vendor is going to exchange the LCD screen for me but my question is could this be a problem with the phone itself and not a bad LCD screen, being that my damage came from falling off and then being run over by a car? I don't want them to have to send out another LCD if my Atrix 2 just won't work any longer.
When I had the phone apart there was not any visible physical damage to the board or other internals.
Thoughts, suggestions?
Apologizing up front for the Portrait video.
http://youtu.be/l2t6TmVsets
Here is another video. Again sorry for portrait but I wanted to get the whole screen on the screen.
Its a screen problem, LCD cable/connector problem to be specific... if it was a GPU problem, the HDMI wouldnt function either.
Hey guys, quick check in. It seems all my coworkers and friends who have the N20u have this problem at certain stages.
There's reports online of excess glue during teardowns and it seems like it's staining the display. Samsung has been super lack on replying back to me with answers.
Mine was perfect until it started to show slightly around the camera cutout, then within the last day it's a huge chunk of the center of the display. So it's something that happens fast and suddenly. What do you guys think?
Display failure. I highly doubt the adhesive is "staining" the display. That outline doesn't correspond to the internal parts.
Manufacturing defect in the display it's self. Perhaps heat fried display drivers from excessive CPU heat ie insufficient heat sink capacity. There's been reports of poor heat sinking on at least some of these devices.

Well they're calling it samsung glue gate, it's happening to phones older than a year and it's a actually very common in many parts of the internet.
I'm surprised it's not big on XDA yet but we are more fanboyish then the rest of the world.
I absolutely love my note, I still plan on keeping it even with the discoloration.

I can't see how it corresponds to any of the internal parts on the teardowns.
All the newer Notes use lots of double sided adhesive strips. It's pretty much chemically inert.
Displays can be damaged by heat and pressure, like a battery failure. A control portion of the matrix of the display ie drivers may have been damaged more likely by heat but maybe pressure. That would explain the odd shape and size. The actual damage portion could be very small it's self but effect a large area.
Try running Screen Test to get an idea of what group of pixels are damaged to get more clues to the cause and actual damage.
I have this issue on my N20U. It was much worse at the beginning but I read that putting the phone in direct sunlight would solve the issue. I did that for like 30 minutes and to my surprise it almost went away. It has been a week after I did that and I barely see the rectangular shadow on the grey backgrounds as I used to see them before.
I still don't know if I should get a new phone, is this issue serious? I mean does it lead to the screen dying on me suddenly or not.
I hope some expert answers

The point is that this defect follow exactly the same rectangular shape with that oval part at the bottom on all the Note devices I saw online including mine ofc.

If you look at the teardown vids or pics you can see that none of the subassemblies or components match that position*. Therefore the defect is in the display itself especially if you can alter its appearance by heat.
It could also be a failure on the mobo but that's probably less likely vs a display failure. All the display drivers are integrated into the display. A AMOLED display is a very complex, busy piece of hardware.
It should be replaced... that's my estimate.
Since the introduction of the variable rate displays all manufacturers have been having issues some more, some less. Most of the issues are with color rendering, but some are outright failures. You see very little of this with the Note 10+ even after 2+ years.
*I'm referencing the OP's original post. If yours differs see if a subassembly matches up with yours. Samsung makes extensive use of double sided tape in the assemblies. As I stated earlier the adhesive is pretty inert. It may be putting pressure on the display if the wrong tape was used or not mounted to specs or a part was out of spec. Samsung will substitute parts due to shortages during a production run. This is introduce unforeseen consequences.

I already checked that and had the same conclusion that it had nothing to do with any of the internal components. But I still can't understand how all the phones have the same (Gluegate) pattern

Samsung possibly scotch-taped our phones? lol.
Haven't had any issues w/ my N20U.
Do y'all have screen protectors on your phone that have glue gate?

It may be a plastiser reaction between different incapable plastics. If so it will get worse.
This is more likely.
Lol, anything you read on Reddit needs to be taken with a grain of salt.
It doesn't matter what it is, it's a Samsung defect somewhere with all notes it appears.
I don't think anyone knows exactly, I don't think Samsung will disclose it's defects, all we should care about is they acknowledge their mistake whatever it is.
Frankly I don't care what it is, it's still Samsung's fault and your note display will eventually show this as well. I've seen so many already, I thought mine was perfect untill it's not and happens overnight almost.
Hey everyone.
This problem exists, and you can change the display under a warranty or insurance.
"But if you don't have any of those here is a quick & tested fix for the issue known as "Glue Gate
Leave the phone under direct sunlight for over an hour and boom, all of that stuff will disappear.
Cheers.
Getting similar issue on my note 20 ultra.

It may be related to a jig or process used in manufacturing the display. Maybe an incomplete UV cure but not sure what if anything display component related is found in that rectangle.
It may be a stiffener or a damping component of the display. Interesting... and very annoying.
The defect may be only present in certain batches.
I'm even more glad I stayed with the N10+'s. Samsung's got sloppy after that, lots of different problems in multiple models. Pretty sad that Samsung can't stop dropping balls. Even their designs suck now, but look at all those glowing reviews. Fake news, fake news everywhere...
My N20U (Android 12, One UI 4.1, latest update: Sept. 2022) does not have any display issues...yet...but have noticed that when the brightness is set very low, the display is too bright.
Using N9 as daily driver instead of N20U.
@asimklicks
Sorry you have screen issues w/ your N20U.
