[Q] Monitor Temperature - Galaxy Note 10.1 Q&A, Help & Troubleshooting

Two days ago my note 10.1 GT-N8000 came back from the Samsung assistance after the replacement of the glass and the display even if only the glass was broken.
All good, they did a nice job and the price was not too high but now the new display seems to have a different color temperature...
I set the screen mode in the settings on standard the brightness on full and in comparison to another GT-N8000 mine seems to be less bright and with a white a bit yellowish
Any advice?

Grainy Screen?

Is it just me or the screen is grainy when in low light and in darker images?
same here, very disappointed in this camera
Yes , it's like a very thin layer of dust or paper is on the screen .

I think this is common with OLED, I've only seen a handful of them though...check out another OLED device or TV in store & check for it.

Is it a common problem or common in all oled? If it's a problem I'm going to return the phone. It's noticeable when you watch videos without light and lowest brightness.
Its common with this phone, not with oled in general.
If its just grainy then you are in luck, mine has clear vertical and horizontal lines.
I believe its called mura with oled technology.
My galaxy nexus a few years back had it way worse and i traded that in after 2 days at the store for a galaxy s3.
My galaxy s3 had perfect screen (to this day it is still perfect except for the cracks in the screen)
Trying to sell my g flex 2 as i have a taiwanese imported phone (h959 red 32gb) in europe and LG webcare refuses to help me with it (and sending it back to vendor will cost me tons of transport and import again ...).
Also LG webcare stated it was normal and even a screen replacement wouldn't fix much. So i was kind of bitter and told them they where 4 years behind on samsung in oled technology if this is normal.
Anyway, good luck with it.

I'm not noticing any major grainy areas, at least it's less noticeable than on my Galaxy S1 & Vita. I unfortunately got one with yellowing along the bottom edge, but I can only see it on light colors.
Also the Mura effect consists of black blotches on black areas, those lines you have are something else.

Mura is cloudy effects on the screen, eg yellow spots.
Banding is lines.
I got both and LG refuses to fix it.
POLED

Yes, true, it is common with this phone and not with OLED technology in general. Now, what else you need to note is that this phone uses POLED type of display. POLED differs with regular AMOLED and OLED display technology in the plastic substrate that employs as opposed to the glass substrate in regular AMOLED/OLED displays, hence the letter "P" in POLED. Plastic is used to make the display bendable and this POLED technology by LG is not perfected yet. I do not know if Samsung uses POLED for S6 Edge, S6 Edge Plus and Note Edge, if they indeed use plastic substrate in their curved displays, then your claim that LG is behind in this tech. is true. I think i've read somewhere that Samsung uses normal display tech in their curved mobile displays, but i cannot remember what website hosted this article.
I own LG 55EC9300 OLED TV and i can tell you that LG's regular OLED tech. is as good as Samsung's. This is not straightforward correlation with mobile display tech. since i do not know of any OLED based phone of LG. My opinion is that LG's normal OLED tech. is just fine, just that they need to polish this POLED tech.
Mine's screen is ok on minimal brightness, however it is too bright on minimal and use Twilight. And than the screen is really grainy. But there is no way around it, 0% brightness is too much at night. I hate that. And there is too much white GUI. We need more BLACKS.

Coming from G2 to G Flex 2 I really noticed non-uniform solid colors on G Flex 2 and I found two solutions: raise average brightness (grain is much more noticeable on lower brightness setting) and get used to it. Really, second option helped me a lot, my eyes got used to this screen within a week and now I don't notice it and happy with overall screen quality. I understand that second solution is not for everyone.

i agree. i use the app darker now. in lowest setting it's usable. but more black in GUI would bee better

Two Edges - two different displays - difference in white and color

Strange thing.
Today I decied to compare the displays of my two Edges - one black bought right after launch, the second one white bought few days ago. Guess what? The display is not the same. There is difference in colors intensity (white one has more strong colors and the white is more clear, where the black one seems darker more dim, like used) Or at least it is my impression. I checked both in the maximum brightness and in basic mode.... So after all, not all Edges just differ cause of processor ? Anyone checked it as well ?
Here we have 2 edges- white & gold, and the displayed colors of the white s7e seem to be a little bit more pastel, but it is not a big different. However, under same displaysettings there are some differences.
Btw the white s7e has the Sony Camera sensor, the golden one has Samsungs sensor. Has nothing to do with the display, just wanted to say.
I think i know where is problem- i have damaged screen . Now i can clearly see that yhe edges of the screen have kind of red tint. Similar to tvs that have their screen burned but here is just one color red. So i guess i have two phones that gotta go under warranty. I will post photos tomorrow .
This is normal by nature of amoled or any other type of screens. They just differ by nature. However i agree your point. Newer s7 edge displays have better whites. I left my device for screen replacement and the new one have a brighter and whiter display compared to old one.

search for my amoled threads, I started quite a few during the last years. and I exchanged every galaxy device I bought a few times to get one with a decent screen!
if you place 10 devices side to side, every screen will be little different in regard to tint, uniformity,...
only about 15% are close to perfect, these are the ones cut out from the center of the display wafer during production!

Hi. I got the device today and I'm fairly impressed with the black levels from this LCD display. Even with low brightness.
The panel, at least mine seems pretty homogeneous and viewing angles are good.
Ah, and I'm coming from an amoled screen (Samsung A71).
well thats brilliant and reassuring thanks Patoilo , I ordered mine a day ago and my context is as a movement and cognition impaired (light and sound sensitivity,reduced memory) disabled dude I keep inducing burn in on OLED displays after 1 year to 18 months AND the PWM brightness moderating method plus pentile subpixel arrangement all mess with my vision and comfort when trying to read. I was super excited to see this combination of 120hz, LCD, big battery etc - the physical size is the only draw back but its mitigated by the reliability of both the screen robustness (not going to burn in or discolor over time) and the fact this thing should last a long time even if I had to go to hospital halfway through it charging
Ill report back about the display when the phone arrives especially stuff like how pronounced any ghosting is at 120hz, how nice the 1080p+ clarity is now that im not on Pentile etc
Im very impressed with the display, coming from a oneplus3 oled, this display is so much better.
Colors are much more vibrant, black level is good and the display is massive in size.
Watching movies in 21:9 with the dual speaker is insane.
One think to note, with "dark mode" enabled it changes multiple colors like white to dark grey, yellow to dark orange etc. so dont keep that always enabled.

Note20 Ultra screen wearing poorly after a year

So I've had the Note20 Ultra 512 GB since release last year. Image retention has always been there, but never resulted in burn in so I ignored that. However, now the screen uniformity is getting worse. The area around the fingerprint sensor and a rectangle about half an inch around the edges of the screen are a different darkness level. It's very visible on gray screens and medium colors at any brightness. I also have an S20+ that is not exhibiting any of the issues I see here. I remember having my Note 9 under neon lights and the half inch ring was noticeable, but could not be seen in normal lighting or dark environments. I was hoping to pass this phone to a family member when the S22 Ultra comes out, but I have concerns about screen longevity. Anyone else noticing this?
See this for an example:
https://www.reddit.com/r/GalaxyNote20/comments/l0svom
The S22U is worse from what I'm seeing; a lot of display issues. Display just going black after a reboot or charge, whatever... dead as Zed.
Plus no SD card slot, no native spen and running on the dog OS Android 11. All that for a premium flagship price. Yes, well...
What brightness level are you running it at?
Use it in direct sunlight except occasionally for a few seconds?
I keep my N10+ at less than 50% about 99% of the time. I use dark mode and near black wallpaper. Minimum red icons. Mostly because I prefer not burning out my eyes but also OLED preservation. I use manual brightness control only.
At 2 years my heavily used 10+ shows no display degradation even compared to my new one.
See what you, use ScreenTest to make sure you actually have any changes with the display. You really shouldn't. If you been conservative with your brightness and you have degradation it's likely a design and/or manufacturing fubar.
Samsung runs hot and cold. This year has been a bad year for Samsung.
Next year isn't any better plus Android OS is tanking. Even if Samsung does manage to pull a Note out of their assets, I'll wait a year to buy it.
See what kind of feedback it's getting and if the Android OS completely turns into a sour green Apple
I punched out and went with a know good workhouse for the next 2-3 years. I just wasn't liking what I saw... and the 10+'s just keep on ticking.

Using it at 40-50% brightness. The screen looks fine in decent lighting, but in a darker room I can see the shaded areas clearly. When using a light theme or pure black, everything looks great as well. I just find it odd how much more noticeable artifacts are on these screens than on the S20+ and Note 9.

That's not excessive...
The ScreenTest app will help you see what is degraded. Blue pixels tend to degrade first, red last.
is the original screen protector still on?

The US models don't come with screen protectors. The glass has held up decently with only 2 tiny hairline scratches that are only visible in sunlight.

Wow I have exactly the same issue. Exactly the ring and rectangle above. I thought it was because of some image that created such a high contrast, but since you have the same issue then it's a hardware issue.
And it's only visible on some shades of grey. Not on black, not on white. So strange
since many devices have the same burn-in pattern, do you believe it has something to do with its internal components (rather than the display's pixels)?
Like the charging circuit for example?
This problem is getting much worse and is now visible at all times regardless of brightness. It likely will result in an unusable screen soon. I will try reaching out to Verizon and/or Samsung to get a resolution. This is totally unacceptable for a phone that only been used a little over a year. Here is what it looks like at 50% Brightness, and 10% Brightness. The Note 9 and 10 Plus lasted over 2 years with no such problems.

Question Xiaomi 12 screen defect?

Brand new after less than a week of use I just noticed that on the left edge of the screen on low to medium brightness, on a background of any color there are bright spots like smudges on the top and bottom of the screen. Which is pretty annoying since it's visible in day to day use.
I'm curious as what is the cause of this, is it a factory defect or is it the pre-installed screen protector? I don't know if this is eligible for a replacement or if this is common on oled displays and run the risk of getting worse displays on the RMA.
Here are some photos using a phone, the camera seems to pick up the stains better if the screen is at low brightness and barely visible on medium brightness, but when seen with the naked eye it is very noticeable be it low, bright and any colours that it displays.
Don't bother, sent it back as warranty.
