Dead Pixels/Burn Spots(?) - Samsung Galaxy S8 Questions and Answers

Hi guys, a friend of mine has a S8 w/ 2 linear dead spots on the screen. Screen off, they look like white air pockets. Screen on with a white background selected the two marks appear to resemble burn marks (?). Has anyone experienced or heard of this issue previously?
He's in the process of replacing the phone via Samsung; they were going to replace the screen, but they then decided to root cause this issue and replace w/ a new device instead. He's had the phone for 3 weeks +, no abuse, never dropped or used heavily while plugged in, etc...
I believe this is different (?) issue than the burn-in issues that has been reported (see attached pic).
Let me know what you think...thanks.

Sorry

Looks like a refund to me

To Samsung's credit they replaced w a new device and gave him a free set of AKG headphones. Just something to be wary of...

I have the same problem - and it hasn't been dropped etc - it just appeared one day

[Q] Touchscreen Randomly Stopped Working

Ok, so first thing's first. I've been researching this for a few days now before creating this post. The touchscreen issues I'm finding online, are similar to what I'm experiencing, but the solutions have already been done, or my phone is not responding to them. I'm making this thread to see if anyone else has experienced the same issues or has any new news before I a) return my phone to stock, b) replace the digitizer, or c) buy a new one or upgrade to the G3.
My G2 was rooted, but kept on stock ROM with only small tweaks here and there. After the latest update, I noticed my work G2 had much better reception, so I returned my phone to stock to download the update. After updating, I re-rooted the phone, this time, the only thing I changed was the keyboard which I replaced with the G3 keyboard. Everything was fine for months until about a month ago.
It started with not being able to pull down the notification shade on the right half. No biggie, but after a week or so, it got worse. While using instagram, I noticed that the confirm button was sporadically responsive. Sometimes it worked fine, other times it didn't work at all. It began to progressively get worse on an almost daily basis. I decided to see what was going on and enabled both input options in the developer options menu. I found that the entire right side, about 1/8" was not responding to touch, the area not covered by glass screen protector( i removed it later while trying to troubleshoot). The upper right area showed about a half inch block that wasn't responding (the area where the data ribbon is). I was ok with that as instagram was really the only thing I used being affected.
About a week ago, the mid left screen area started being errratic. It began to get worse and started to affect the front touch screen buttons ( the area where the other data ribbon is). I enabled the input options again and saw that I now had a good portion of my left side of the screen was unresponsive. Even though I didn't drop it, I thought maybe the data ribbons had come loose as those 2 areas are where they are. I opened and disassembled the phone and re-sat the connctions after inspecting them. I double-checked all the other connections and LDIs in case humidity was the culprit. Everything looked good. Didn't fix the problem.
I've had to set my phone to unlock by facial recognition to ensure I don't get locked out, and changed my pin to use numbers not affected. I'm going to replace the digitizer, but wanted to see if anyone else had the same issue, or knew if it was, indeed, a software issue before I spend $75 (I will be replacing the digitizer and LCD to get it working sooner rather than risk damaging the LCD while replacing the digitizer and having to wait another week). I don't want to send it in to LG because I bought it on ebay and have no proof of purchase for warranty, and I want it working sooner.
One thing I noticed that may help with diagnosing, the screen now looks different when off. Before, in direct sunlight, you could see the dotted matrix from the digitizer, and that was it. Now, I can see the retangular pattern across the entire screen. I checked my work G2 which I just received a few months ago and the rectangular pattern is only visible on the edges of the screen, the center is black with only the dotted matrix visible. Keep in mind, this is in direct sunlight. In shade, the rectangles are visible on both.
I'm hoping it's a software issue, but I'm wondering if the digitizer is starting to separate from the LCD. I don't see any acutal separation though.
Thanks for reading the book, and for any feedback. Also, because it will probably come up, I want to avoid upgrading if I can because the G3 is just a little too big.
I restored the phone to stock with the most up to date software. Still doesn't work. It appears to be a hardware issue. I really thought it was software because the dead spots word for a split second after turning on the phone. Oh well. Guess I'm going to order a new digitizer or LCD combo.

[Q] Warranty repair for black lines

Hello all, today I've noticed that my G2 has developed the infamous "black lines" accross the screen problem. I have black lines all over the screen vertically and horizontally. The lines appear to slighty flicker and they're constanly visible in all colors, but mostly in lighter colors. The phone is in a good state, few scratches here and there, dropped it once before (~0.5 ft height). The phone is around 10 months old and I use it intensely every day so I'd see if started happening after the drop, it didn't. My question is, does the warranty cover the screen replacement or adjustment (because I've read that it may happen because of the screen connector being loose) if it has the black lines problem? I don't want to open it myself and fiddle with the connectors because I don't have the skill required and I don't want to mess something up while it's still under warranty.
PS. Never unlocked/rooted/flashed, model D802
Thanks.

Warranty will cover it, when you contact them tell them you have tried all types of resets and factory restore.
They will issue you an RMA. Make sure you have the receipt of when you bought it, you will need to send it in with the phone.
I was going to send mine in for RMA but they wouldn't cover it under warranty because I bought it on EBay even though the actual phone was less than a year old.

[Q] Mysterious vertical light banding/gradient.

Hey guys. I have this phone for almost a year now. This problem was quite a while back but now.it seems more annoying to me. When on a gray/dark gray background, such as the quick settings toggle on Lollipop. I can see TWO banding or gradients that WHITEN the place where they are. They are arranged like 1 cm from the left and right edges of the screen. I don't know why they are there.
Questions:
1. Is it because of the battery? Like if the battery got swollen, it pushed the panel. BECAUSE THE BATTERY ALIGNS PERFECTLY WITH THE GRADIENTS ARE PRESENT.
2. Is it because of a faulty LCD Panel? Since this phone had no falls whatsoever, im not sure about the LCD being faulty
I think its the battery
WHY BATTERY?
1. Because the battery might push the panel from the back.
2. The phone when i bought it new had a little *creeking* when i pressed from the side of the sim tray and the bottom. But now there aint. Its like its tightely held up. Something a swollen battery might indicate.
3. The battery life had been worse over the time.
4. I use the phone quiet alot when on charge. So.. Yeah
If anyone has more knowledge about the case. Do leave a response. I will be THANKFUL TO YOU. even a little information will be appreciated and will be THUMBS UP accordingly. Thanks!
Bro i got the same problem. The LG G2 my second phone and this line suck monkeyass. Dont take it to the repair or something it gets worser and worser. LG(Netherlands) also confirmed that this is normal and its written in their specification. I told everyone that they have to buy LG phones but now i strictly say dont buy this phone. I know 3 more people with different screen problems on the G2. Sell it! And dont touch any LG phones.
aame
Ive had this problem on three of my g2's. The first wasnt that noticeable, it was on the right wdge of thw screen. i got it replaced due to permanent lines.
The second had the EXACT same problem you describes, but i noticed it right when i got the phone. It looked like something was pressing too hard on the bottom right corner. Got it replaced.
The third one had a similiar problem. But right in the middle of the screen. When i press anywhere on the screen, rippling appears in the middle of the device. Its as if im pressing in the middle of the screen to hard.
Im currently on my seventh g2, all verizon variants. These phones are GREAT phones performance wise, but they are complete sh1t in every other aspect. Ive had every problem you can with these phone. Screen problems, headphone jack problems, speaker problems, mic problems, and camera problems. Im now saving up for a oneplus one device.

Internal LCD broken

Hello guys,
I've had the Samsung S7 Edge since august, have always cared for it (i.e. never dropped it, etc.) when all of a sudden, while I was playing Sky Force Reloaded and charging (with fast charge) when I closed the game and turned the screen off, and back on, it was crazy. The image would be flashing white and this flashing changed with the luminosity (when was full luminosity was fine). I also had AOD, and there were no problems there, the screen worked fine. This was until I restarted the phone (though it was a software problem). After the reboot the problem got worse, and I could notice different brightnesses on different parts of the screen, when I could stabilize the image, using full luminosity (and having the setting fixed. As soon as I clicked automatic brightness, It would go mad even with full luminosity).
Having the phone for such a short time, I went to the samsung responsible repair place in my city (there is no official samsung here), because they work with samsung and evaluate the warranty and fix if the defect is on them.
Well, they told me the screen was broken (there was not a single scratch on the outside, which means that only the internal LCD broke somehow), and told me It was misuse.
My question is... How is it possible to break the internal lcd without a fall, without a scratch on the outside and having it to work on some software settings? Because I don't trust this repair shop, or their technicians (they have several bad reviews involving screen defects... they always assume broken screen), and the screen replacement is not really cheap.
Thanks in advance.
I had a similar issue with mine. It was a pink line across the screen from top to bottom. I contacted Samsung via the Samsung+ app and they had me send the phone to them and they replaced the screen free of charge.
Hardware faults can happen at any time, no matter if you drop stuff or not.
Does your screen flash also in Download Mode? AOD display?
Anyway, your responsible repair place is a sh*thole... "misuse" lol.
If you're not rooted Samsung will give you a warranty repair, at least here they'd do it here at my local Samsung repair center.

LeEco Pro 3 Display

I have this beautiful and powerful phone LeEco Pro 3 that i`ve been using for half an year or so with AOSIP ROM. Its a wonderful phone with an amazing performance.
The thing is my display started a problem history that has become a long history i will try to resume in a few words.
It started in one day i pressed the power button in order to light the display on and check something in an APP i needed. I found out that before the display lighted on some weird colors and artifacts appeared on screen. But indeed the display worked fine.I thought it was just a temporary thing and just kept using it until In the second day that the weird colors and artifacts became permanent, so i realized i was in trouble. :crying:
Tried sending the phone to technical assistance.
The first one - Told me that they could get a new display for testing but indeed the results were the same and they were seeing oxidation in the display connector on the board, not the display flex cable but the main board connection. They said they would not go further into it and they decided to give the phone back to me. Weird thing is that when i turned the phone one it worked for one day without issues. He said the phone was in the same condition, but that is not what i saw. The problem indeed happened again one day later , but it was less worse as i could at least see the screen, but almost half the screen was horribly shaking, trembling.
The second one - Once the tech guy looked the phone he said he didnt see any sign of the phone getting opened. He said he would be seeing signs of glues or anything like that but in his opinion it was definitely not opened. But he warned me the display could physically brake once he opens it as the phone got contact with oxidation in the toilet(I used to left it in the toiled while i take bath). So i was afraid and decided to back off.
The third one - Said he could not find any display so he sent the phone back to me. Didnt open it at all as he was trying to wait for the new display to arrive in order to be safe. They said they are 90% sure its display replacement would do the job. The thing is - if i used in hot environments the issues seems to slowly disappear . If i use it in cold environments the problems seems to get worse
So here i am. I CAN buy another screen over the internet. But i am afraid if it will work or not. Have anyone there faced same issue? What do you recommend me to do? What would you do
Thanks in advance

There are many many post on this subject, recently in fact. That has links. In fact, you can find them on Alibaba that are all black and made specifically for the Le Pro 3. Here is a link of a guy who used the cool s1 display
Yes it sounds like the display or the flex cables.

Here you go cheap and they have the black one
