Wonky Pen Tracking Near Top and Edges of Phone - Samsung Galaxy Note 8 Questions and Answers

Pen tracking on my phone tends to be off by a bit in random locations around the top and edges of the phone... Anyone else have similar issues?

Something magnetic, such as a magnetic case can interfere with the pen. I know this from 1st hand experience!

There is no case on the phone

Should I swap out the device? Or is a .2 to .5 mm x,y variation common?

I think every single Note 8 will have this issue buddy,
It happens on the bottom too leading to believe its the frame of the phone that is messing with it.

If you truly observe a defect, exchange it. If you're being OCD'ish about it and decide to exchange it, you'll risk recieving a unit with a ****ty display!

Samsung is know for inconsistencies in screen uniformity, i.e. some of the Note 8's has more of a reddish hue than others by default. Or one may be a bit cooler in color than another. If either is not of your preference, and the display you currently have is acceptable for you, exchanging your current unit will put you at risk in receiving a unit with a display you may feel is ****ty in comparison to your current.

Agreed!

My screen does have a definite red tint when tilted. Is this common for all devices. Should I exchange? It was bought from att, so if I do exchange, I'm guessing have to go to an att store?

The sad state of my Nexus 7 screen...

Really disappointed - when I turned on my Nexus 7 today, I found a line of dead pixels. Immediately called customer support and they said try to reset the tablet to see if it's a firmware issue, but it still persists. Will be sending my tablet in pretty soon to have this fixed, unless you guys have any recommendations.
While this might make it sound like I'm ragging on the manufacturing, I actually love the tablet. It's extremely well built - feels great in hand, has the right heft, but is still light and extremely rigid. If any of you are on the fence about this tablet, you shouldn't. It's hands down the best deal that's out there.

That sucks really bad. If I receive my device and anything is wrong with it, I'll probably die. I hate when my devices aren't perfect. Also, like the last poster said, is it a pre-production unit?

Not Gorilla glass, Scratch resistant Corning class. Though I don't know the difference. I know my G2 was stated to have Scratch resistant corning glass and it never got a scratch in almost 2 years now.

You're definitely right. However most stuck pixels are of a color variety, dead pixels are usually just that and are completely black. If its truly dead, it will stay blacked out regardless of any action.
I am surprised though that a line like that took that long to emerge or die off, I'd have expected them to die off in production or qa. I'm curious if the op dropped or even bumped the tab at some point.
Anyway I hope the RMA process isn't too long and that u get ur tab back soon.

Yup. So I called ASUS and they can't even issue me an RMA because the tablet hasn't be officially released yet. I'm gonna contact Google tomorrow to see if they might be able to replace the tablet for me, really hope that's possible.
Whatever happens, I just want a functioning screen on a white Nexus 7!

You probably won't be able to get another IO model.
Based on the teardown video u can just swap the backing if they let you keep your current model until you get the replacement.

Screen size of galaxy nexus vs nexus 7.
I made this diagram for another thread on here.
Sent from my Galaxy Nexus using xda premium
By the look of the picture, the pixels on the LCD itself might not be dead. It could be the LCD driving controller, or one of the electrical connectors have failed since all pixels are connected in rows on the X-Y plane. The electrical connection on that particular row may have failed, so you see a complete row of dead pixels.
There were screen quality issues with the transformer prime and the tranformer when they were released. I was hoping ASUS got their QC figured out by now or Google made them have a higher threshold during QC for holding them back. I am hoping I don't need to go through 3 of these like I did with my prime due to screen issues like stuck pixels, dust under the screen or white spots.
My IO N7 screen started to separate from the bezel on the left side and the white back started discoloring into blue/black.
I hope the production units are build better.

Question about metal bezel on note 4

Got my replacement note 4 a few days ago,and noticed that the metal bezel sits a little bit higher off the glass on one side then the other,was wondering if this is a normal ,and by off the glass referring to metal lip around glass,not a huge deal,but...None the less it's there.
Your saying that the metal trim....is thick? As in its raised a couple mm? Mine Has It Straight All around....Not Going Above Or Unto Of The glass.
Lol I mean the metal trim raises above the glass,but not evenly.
Yea it's raised above the glass....but evenly lol BRO just enjoy your phone already don't dwell on it bro

Dude I think that's your "gap". Every note 4 has one. it isn't that much a problem like I thought I'd be. I clean my screen all the time hate fingerprints and smugness but I'd say it's "normal" according to the Galaxy Note 4 manual.

Little physical imperfections like that are pretty common with all phones. My Note 4 has a slightly loose power button, my Nexus 5 screen was about a millimeter higher on one side than the other...
Unless it's really causing an issue for you I wouldn't worry about it.
I can live with Minor imperfections like this since I trade up phones ever year but screen issues are a big No No for me. God gifted me with 21-21 vision.

[Q] Light Leakage Around Bezel?

So last night I noticed that there appears to be a thin line of light coming up from above both the right and left bezel. Can anyone else reproduce this? It's most noticeable in a dark environment with the screen brightness relatively high.
Red line indicates where the light leakage comes from.
here are some actual pics. I just want to know if this is normal or not. Thanks
Nope, your phone should not do that. It appears your screen inst adhering as it should. If I were you I would take it back and get a new one if you're in your 2 week grace period.

Thanks for your reply. Unfortunately I'm not. But I've reached out to Samsung and they acknowledged the defect. Hopefully they'll send me a like-new replacement.

So in the end I did end up getting a replacement because of this. Turns out I'd totally regret it because this is actually normal behavior.
The replacements I got had far worse issues such as yellowing screen, overheating, and rotation issues. And on top of that all of them still had the light bezel bleed. Ugh.

Do you have the same defect I have on my screen? :(

Mine has it... Does yours? I wish I didnt see this but there is definitely a defect there....

No such issue on my Midnight Black Note 9 (N960F Exynos, 512 GB). Never had any on my Note 8 either or the Samsung flagships I owned before that in the last 4 years.

You can't really tell during the day. If you look in a dark room it's obvious once you see it.

It's light bleed. Check this thread out in the Note 8 section. I'm not sure if Samsung will cover it under warranty so your best bet is to try and return it for another and hope it isn't any worse. My Note 8 has it some and my son's dose not but a case easily covers it. I'm praying and hoping my 9 arriving today is perfect. Either way from reading it dose not affect the water proofing but is annoying for such a expensive phone. I wish you luck.
It does not bother me too much. Rarely are you concentrating on one side of the phone. I think most have this but they don't know exactly what they are looking for which is a good thing. Only at night you can notice it
No bleeding on my phone. Sprint blue.

Only a few of them will have light bleed. It's only visible during dark room conditions. I wouldn't even call it a defect much less an issue unless you bareback your phone. Fortunately, having lightbleed doesn't mean that the device isn't sealed, it just means the painting on the phone isnt dark enough at those parts you see the light.
I'm happy to report back I have no light bleed or any other problems so far with mine. Just got it 10 mins ago.. time to play.
No
I've got 2 Note 9's from AT&T (from Sam's club) and neither have the defect. Looks like the case is not sealed all the way. May be easy to cover up?
Just so you guys know, it may occur either way in the future as your device ages. Whether it be from heat or cold, but it will happen. Your device waterproofing shouldn't be compromised though.
I really believe it affects almost all devices but people don't notice. Even if you kinda know what to look for it's hard to see. But the problem is once you see it it is very hard to unsee it....

I've handed my phone to 8 people in the past 2 days and only 1 of those people could see the light at the leak. It blew my mind. I would show them exactly where to look, and they still could not see it. Then they walk off shaking their heads like they think I'm crazy. My phone leaks on both sides in 4 spots. I've attached a photo of the worst spot at about 30% brightness.
Ohhh your is on the right side... Mine is in the left

Touch screen issue test / reproduction (video)

Hi All,
I also experience the touch screen issue on my Galaxy S20 FE.

Yes, if you don't experience this, you unit is issue-free. I have also asked others to test, they have no issue at all.
This is why I think that *might* be a hardware/production issue.

Yes, that's what it would seem to suggest - and it's discouraging, I was really hoping this was a software issue. Would the 120 Hz refresh be a factor in this? That is, do you get the same result at 60 Hz?

Nothing. Either under charging or not, either 60Hz or 120Hz, no matter if Touch Sensitivity is set to low or high, it happens.
But as it doesn't happen for everyone with the same software, it tends to be a hardware issue or a production defect.

Thanks for the feedback. It seems not all users are having this issue. If you cannot reproduce the issue following the video instructions, then you are touch error-free. But then, it shows that it is not a general issue, but some manufacturing defect. For the red tint, I have seen your other post, I also have a barely visible greenish one, around where the camera is, and around the bottom 1/3 mark. But as it was stated, it is somewhat "normal".

Good question. I spoke with Samsung Support and they wanted me to visit the Service Center. I told them that I will not spend that much time on it, this phone is too expensive for having this kind of support. I will just return it and ask for a refund, then wait 1-2 months if the problem is solved.
I was just thinking yesterday...
This phone has Gorilla Glass 3 on the display, which is a way different structure than current GG6 (or GG4). GG3 is much thicker and more acts like a glass (breaks easier). Since GG4, newer Gorilla Glasses are more flexible, thinner, and more durable, too.
What if Samsung has just put a thick glass on top of a modern digitizer (touch panel) which was designed for a different structure and much thinner glass layer, and this causes the touch problems?

I notice it under normal circumstances like browsing, while straight looking at it, when the page background is like pale yellow/orange. It is only a bit visible, but when you read text and scroll, it is disturbing that the greenish tint remains on the screen. But honestly, this is not that bad. On a white background, I don't even notice it.
When I look from a bottom angle and moving the phone's angle, the tint bars move as well.

You mean are referring to the green tint correct? Are you saying that you have no reddish/pink tint at all on your phone?
I notice it very clearly when looking at it at angle or even normal position. And I can see it move when I move the phone to different positions.
the XDA review has the same issue actually (nothing on the touchscreen): https://www.xda-developers.com/samsung-galaxy-s20-fe-review/
"The viewing angles, though, are disappointing because the display still features visible angular color shifting to blue as well as a rainbow out interference effect at extreme angles. Newer Samsung OLED panels have eliminated the rainbow out interference effect, and also reduced off-axis color shifting by a significant amount. The Galaxy S20+’s viewing angles, for example, are much better because the color shifting is much lower. Strangely, even the cheaper Galaxy M51 (review) doesn’t feature the interference effect issue (that is likely caused by the polarizer)."

EU. I bought the phone in the official German Samsung webshop. If I would be out of the return period, I would of course take it to the Service Center even with the red tint, but this way, I will just return it.

True, I have no reddish tint, I have some greenish one When looking straight at the phone, it is around the opposite side of the camera, and about a thumb tall. But really, not that visible, I just see it because I know it is there
I read the quoted article. This can also easily happen because of Gorilla Glass 3, maybe it has different inner reflection that causes these bands.

That sounds reasonable...however, what about all the phones using GG5, 6, or above that have a tempered glass screen protector on them, which would certainly make the glass atop the digitizer much thicker, and that do NOT have any touch issues? It seems to me that the thickness of the glass...up to a reasonable measure that I do not know what it may be...is not the issue here because my S20 FE does not have the touch issues. But mine does always turn on in my pocket. So it seems as if the proximity sensor is faulty. I wonder if this "bug" is somehow related to the touch issues. Though they appear to be different problems...they are related to how the screen works. Clearly something is wrong and I am not sure that any of it can be fixed with software. SMH

That sounds reasonable...however, what about all the phones using GG5, 6, or above that have a tempered glass screen protector on them, which would certainly make the glass atop the digitizer much thicker, and that do NOT have any touch issues? It seems to me that the thickness of the glass...up to a reasonable measure that I do not know what it may be...is not the issue here because my S20 FE does not have the touch issues. But mine does always turn on in my pocket. So it seems as if the proximity sensor is faulty. I wonder if this "bug" is somehow related to the touch issues.

You are right, I also thought of it, but not only the thickness, but also the material structure can cause problems like transferring more static electricity to the digitizer that cause ghost touches. And the glass screen protector is on top of the screen which is far enough in distance from the digitizer. I can also imagine that combining this digitizer with GG3 would require less manufacturing tolerance than they used, and that causes just too much defective units. Just guessing...
But as you also stated, problems are mostly with the screen and touch panel. Ghost touches, incorrect finger recognition causing jerks, pocket wakeup, reddish/greenish tint on the screen. And +1: not all users have this problem.
If this would be a software-related issue, all models would be affected more or less. If some units are fine, some are wrong, with the exact same software, then it should be a hardware-related problem. Question: do they used different brand of digitizers for different units, or there is just a huge ratio of defective units coming out of the factory because they had to put as many units on sale as they could because Pixel 5 and iPhone 12 has arrived and they wanted to catch a lot of customers? Just guessing, again...

True, I have no reddish tint, I have some greenish one When looking straight at the phone, it is around the opposite side of the camera, and about a thumb tall. But really, not that visible, I just see it because I know it is there
I read the quoted article. This can also easily happen because of Gorilla Glass 3, maybe it has different inner reflection that causes these bands.

So strange, every one of the phones I looked at in the store has these bands. Surprised yours does not.

If watching from bottom angle, I see the bands, but in straight view, I only see some greenish tint. It is not very disturbing for me. I mean, I have a LED TV, which has some of these typical IPS clouding effect on the screen edges. 99% of the time, it is not visible because the content is bright. But when watching a movie that has a night scene and there is no ambient light in the room, it is awful. But in general, I like the TV

Interesting, thank you for the response. I see the red tint straight on and at angles too, so maybe we have a similar issue but a different color?
I also have a LG OLED, which can look quite bad in some very dark scenes because of banding.

That might be the case! Different color, but the same tint / band.
