S7+ AMOLED quality? - Samsung Galaxy Tab S7 / S7 Plus Questions & Answer

Hi all,
I would like to get some feedback on the AMOLED display quality in regards to uniformity when displaying a grey screen?
Did Samsung improve anything here or do the AMOLEDs still have clouding issues and the displays are not really uniform?
I have a Tab S3 and Tab S4 both with some clouding visible especially when displaying grey and dark grey.
Thanx in advance,
am

From what I have seen the AMOLED display on the SGTS7+ is actually pretty good for watching videos, the colors are excellent and so are the blacks.

It's an excellent display, as long as you use it over 30% brightness
As soon as you dive under 30%, it's a color-calibration sh**show, with a huge green tint issue (pretty much the same thing for any high-refresh rate displays of 2020. This issue was fixed by the following generation of displays, with the help of LTPO technonology)
I use it 5-6h per day as laptop replacement, and it's a blast during day time. But as soon as I want to watch movie at night time, the green tint forces me to push the brightness higher than my eyes wished.
The severity of the green tint will vary from one unit to another, but no one is spared.

PLS screen as compared to other IPS screens

With the significant drop of SuperAMOLED quality control or just plain bad luck on my end I've decided to call it quits and look at other screen technologies and suffice to say the rumored Tab 11.6 is peaking my interest and probably that device will come with PLS.
I've had a chance to compare the Tab10.1 and Ipad2 but I really didn't do so extensively, I was comparing the TF201 , Ipad2 and Tab7.7 and after a lot of testing I've concluded that SuperAMOLED only offers better blacks, the rest is just a subjective preference like color saturation, even viewing angles are superior on the TF201 and Ipad2.
My primary usage is video playback then web browsing, Im also particular with white tones across all brightness levels and with my current Tab7.7 the white tones at low brightness are just horrible compared to the TF201, Tab10.1 and Ipad2
Anyone with extended experience on the said devices can share their opinions between the PLS on the Galaxy Tab 10.1 vs the IPS on the Ipad2 or TF201?
BUMP for my post, how does the Tab 10.1's screen perform in terms of movie viewing?

Pretty good when the brightness is turned all the way up, This being on Dice Player @ 255/255, Better contrast and color, I think Bravia engine can be added to enhance the colors.

about 95% of the time I use the device at the bed room, so 0-33% brightness might be up my alley. When you say better contrast and color is that in comparison to the Ipad2 screen ?

I watch a lot of series and some movies on my Tab while in bed and imo it's pretty great (especially when they're 720p ). It's almost always at night so no problems with the sun shining on the screen though. With the sun shining directly on the screen, I doubt you could really enjoy any movie ...
I have my brightness set somewhere between 50-100/255 on Dice Player, depending on the movie and if I have any lights on in the room.

Yeah around daytime it's best on 255 but around night time I keep it to 150 or such, any higher at night is like an alien abduction
Hmm on a superamoled screen i keep it at 46 only. But that doesnt really matter as long as the whites in web pages remain white unlile oled.

Strange, it shows the same color for me both on computer and on the tablet. I *did* have the "white xda" problem in the past though, both on my desktop, laptop and tablet. Thought it had something to do with a faulty .css or something similar though, haven't seen it in a long while now.
What I mean is on low brightness levels the white tones on the SuperAMOLED screen becomes either grainy or may turn into yellowish,pinkish or blueish depending on the the screen you've got. Though movie quality is great I also noticed it makes an actual scene darker crushing detail.. Samsung tried to fix this with a different gamma profile on the Galaxy Note but it ends up giving blocky blacks.
I've come across a store demo unit and sadly I cant transfer over my media files, BT just takes to long and the Tab10.1 has no wifi direct.
Is backlight bleeding a common issue on the pls screen?

PLS is plane line switching where as ips is in plane switching. The only difference between the Displays is the light thourough put is higher in Pls that ips hence the more vibrant colors and brighter backlight

Droid DNA screen has blue tint?

I've noticed on hands-on videos that the Droid DNA has a blue tint on white backgrounds. Some reviewers have also mentioned this and the cooler nature of the colors. Another thing I've noticed is the colors seem less vibrant compared to the One X, which was more colorful and warmer. The blue tint was the first thing I noticed while all these review videos were extolling the greatness of the PPI. The blue tint on galaxy phones drives me batty, and this one might not be that different. Do you see the blue tint on your phones? My local Verizon store only has dummies. I might just wait for the Oppo Find 5. I really like how the screen looks on that phone.
One X was uncomfortably warm for me. Too yellow which I didnt like.
DNA is little more colder but colours still pop nicely. Much better contrast compared to One X that I had. It is right balance between what we have seen with One X and SMOLED display that my Note 2 has.
There is definitely no trace of the typical blue tint you see in AMOLED displays. It is definitely whiter than SGS3 and Note 2. But not as yellow as One X. It is perfect actually. You can never judge screen seeing videos. Choice of wallpaper, camera sensor and room lighting play huge role in how things look on camera. There is no doubt in my mind, this is best display I have ever seen on Mobile. PERIOD.
Maybe many reviewers are coming from One X which was considered to have best 720P display. But frankly for me it was too yellow to be natural.
Thanks for your reply. I have to disagree with you about not using videos to judge a display though. Every phone I've bought looks exactly like how I've seen it in videos. There are poor quality or off-color videos of course, but those are very easy to notice and disregard. With high quality videos, especially when you have the phone next to other devices that you've used and know how they should look, there's no room to blame the video. Apple's displays always look so good because they calibrate it properly. HTC and others need to take a hint. At least provide calibration software onboard if you don't want to do it manually for each device.
I've had a few replacements of the DNA for various issues and I noticed that they all had slightly different calibration profiles with whites of two of them being slightly red tinted and the others being either slightly blue tinted or in the case of the one I currently have, closer to neutral but the colors appear to be slightly less vibrant. They're all over the map, so I think it's just the luck of the draw. One thing I have found consistent is poor backlighting with shadowing on different edges of the screen on different units, especially the bottom (near the capacitive buttons). The pixel density and size is definitely phenomenal, but I miss the balanced calibration and completely even backlighting (to the edges) of my 4s.
No blue tint here.

How much does the screen uniformity issue affect night mode e-book reading?

Reading e-books in night mode (dark brownish background and yellowish font) is the only situation where low light performance of the screen is critical to me. The QHD screen on the Note 4 performs admirably in this regard. The brightness I use is around 5%.
I'm worried the P-OLED might blur the font edges and give them a grainy look, effectively negating the benefits of a higher resolution screen over 1080p. I would not wish for any extra strain on the eyes; I tend to read every night in bed.
Any night-time e-book readers that own the V30 out there?

Asking for other e-book readers experience is smart, but be aware your "5%" on the Samsung Note 4 may be much different on other phones.
What is your "5%" in lumens? Give us a real number. Each OLED OEM sets a different minimum brightness level. Saying you like 5% on Samsung Note 4 is useless. That might be 20% or 25% brightness of the LG V30...
That's what Google did for the 2017 Pixel 2 XL -- even though they use the same LG display as the V30 Google set a much higher minimum brightness level. 5% of the Pixel 2 XL is 25%, 30% of the V30. LG lets their display get MUCH darker.
Here, go read this and look and side by side pictures.

Yes, I am aware 5 % on the Note 4 is not the same on the V30. I just mentioned it in passing, could just as well have said I keep the screen on "almost as dark as it gets".
I think a further question is, are the display issues less noticeable on dark brown/blackish background vs. the grey most comparisons use as the example?
I keep the background not-quite-black and font not-quite-white (in ither words: yellowish), because it's easier on the eyes than the contrast of simple black and white.

Issue about Realme XT Amoled Display True deep blacks.

Hello RXT Users,
I bought a new Realme XT (6GB,64GB, Pearl White) Mobile, which works like a beast.
But within a week, I accidently noticed that the true deep blacks of Amoled display actually kills the surrounding Grey colour pixels especially in videos (or moving frames).
When I using Instagram, Samsung just posted some photos. when I try to swipe one photo horizontally, I noticed that the gradient colours (White to black) are like vanished some time and and a bluish shade is appearing btw the blacks and whites.
Then I started comparing this with other LCD panel, which is not doing these weird things. I also did a side by side comparison btw Realme XT and other LCD display by playing a dark horror movie. The results came was not expected.
First things first, the picture quality, colours, contrast and viewing angles are awesome in Amoled display, But the grey coloured details which are nearer to the black pixels are missing, they are completely gone.
Example:
• Original frame in the movie - A dark room with cupboards and interior.
• Picture shown in LCD display - white blushed dark room with cupboards and interior.
• Picture shown in Realme XT - A Deep Dark Black room with no interiors no cupboards or even no walls.
I can't understand why the Amoled display takes more time when pixels changes from black to grey colours, may it's because of low refresh rate.
Can anyone please tell the display refresh rate of Realme XT and try the above tests to clarify that I am not the only one who got these weird thing. Thanks in advance.
Note: I am using Amoled display for the first time.
This is quite disturbing to know. I was planning on buying XT and returning my Poco armoured, as it has ghost touch issues and I don't need that much processor power for daily usage.
Also, with XT getting started on development I hope I won't miss Poco. But with the above-mentioned issue, I'm getting skeptical because my primary reason to get XT was AMOLED display. I don't want to get disappointed by it.
Although it doesn't has ambient display and dark mode yet but I hope it'll be there in future updates.

After reading this post I checked my xt's display for the greys in dark scenes with my le 2 LCD display and I'm pretty satisfied. I was able to see most of the details of dark scenes that was visible on the other phone. Plus I found it's very vibrant as compared to the le 2 and brightness level is also much better.

Thats how amoled works.. Not problem phone.. Amoled screens are like that..

Tab S4 vs Tab S7 display

Hi All,
I'm currently using Tab S4, but I want to switch to S7 11 inches. As we all know there is a LCD display.
Generally AMOLED is better, but do I see big difference between these two? I could order S7+, but it is just too big for me.
Can you please advise? I don't want to be disappointed every time I look on my new tablet.
Thanks
personally i would go amoled anyday. lcd the blacks will look dark grey.
Accustomed to the AMOLED display now going back to a LCD... eeh. Since i like having most of my stuff in dark mode anyways, the AMOLED will be considerably better on battery life for me. Even it being slightly bigger (1" x .5" roughly) vs the S4.... 12.4" screen imo would be worth it. I'm looking forward to the S7+ myself!
Going from tab s4 to the s7 plus screen is seriously impressive.
The screen with 120hz is the best I have ever seen.
I use my S4 as a huge google maps / waze GPS when in the car, is the S7+ screen outside the legal limits if you get pulled over? I think 11 inches is the largest screen you are allowed to have ( United States)
I have both the Tab S 7 and the S7+.
Avoid the S7 as the screen looks terrible, dull and pixelated. It doesn't even hold a candle to the screen of the Tab S3.
In contrast the S7+ screen looks glorious.
I had the tab s4, s5e and recently picked up the regular tab s7. During regular use, I would say there's not a huge difference, but the viewing angles are a little better on the amoled screens. If you watch content in low light, you will notice that the blacks aren't as inky black....but on my amoled screens, I get a bit of black crush/banding when displaying greys at low brightnesses.
I would say that using it is a much better experience than the tab S4, if you include the keyboard case. It makes it much closer to an actual 2-1 device compared to the prior generatios.
No comparison s7 lcd is crap compared to s4 and s6 ambled. S7 plus screen is fantastic. If you want lcd buy an ipad
I have not used other tablets but own the note 9. I didn't expect the LCD to look great after all the reviews. Thankfully I have been surprised by how much I like it. I am drawing, gaming and content and the only thing I wish it included was the keyboard and the themes store. I will get the keyboard later. 11" 120Hz screen is very nice. Having the 5g version this will be a really fun tablet.
Have you people actually used the S7? I have the S7+ but I've used the 11" S7 and it's a really really nice screen. I can't imagine the S4 looks better. Do not be afraid to buy the S7 if it's the form factor you want.
Please stop telling people the S7 screen looks good compared to amoled. If it were true samsung would have put the new LCD on both models and we wouldn't see every flagship phone even from apple starting to use OLED. If you don't care about vibrance and aren't using for media then the s7 is probably fine for you, but that does not mean the screen is as good as OLED, it just means you don't care. There simply are no LCDs that compare to OLED, phone, tablet or TV. The s7 has a well made "nice" looking LCD, the s7+(and S6, S4, S3, S2) have beautiful AMOLED displays and samsung should be ashamed.

I don't think anyone is saying that. I think the point is to compare the Tab S4 screen to the Tab S7. The S7 has a higher resolution than the S4 and is a really really good screen for not being AMOLED.

yup
The next marketing victim.
Simply go to wikipedia or ask s.o. with knowledge. But avoid sponsored reviewers on YouTube living from the stuff they present.
OLED are great for average usage. Biggest advantage: pitch dark blacks and strong contrasts as well as saturation.
Biggest down-side: uneven decay by color over lifetime. -> strongest color shift, burn-in effect...
LCD can be much brighter, have the highest color accuracy and stability, but lack the OLED high saturation and contrasts. Hence, blacks are not really dark.
It always come to the use case.
You wanna play, watch movies, use many apps. Great: OLED is for you. Most people even do not keep their devices longer than 2 years, so burn- in will not appear. Even my 3.5 years old s8 phone have not a really notable burn-in. And for the color shift I care by adjustments the rgb levels.
You want a working device, showing all day long office, use it as a display mount on a wall, showing static areas: OLED will have burn-in within less of a year.
That is the reason you will not find OLEDs in offices, not to talk from company's relying in color accuracy.
There's a reason, companies like Samsung spend billions in developing new techniques like Q-\Micro-LED.
Finally: the s7 has a really great LCD, superior to most others LCD devices. In contrast to OLEDs, it lacks perfect blacks and oversatturation. Does it fall behind professional monitors? Not really - but every OLED will.
If color accuracy is a thing for you? Go for the s7, especially you do not like the bigger size of the s7+. If perfect black and strong contrast is your thing, take the s7+, but remember the mentioned draw backs of OLEDs.
Of course LCD can be brighter, they just put in brighter edge or back lighting at which point your color accuracy and consistency across the device goes to crap. This is one reason why anyone who calibrates an LCD TV set's base brightness quite low.
Either way I'm done arguing, the one thing that was said that is correct is "go see them for yourself" don't believe anyone here(including me) which screen is better for you.
Everyone sees differently. I don't see any colors the same as others do so the S7 screen looks great. Not better and certainly not any less then any OLED I have looked at.
I barely touch my note 9 these days. Love the screen size etc for gaming and watching movies in bed.
I don't know where people learnt that AMOLEDs are better, they are worse than LCD: Amoleds has little more details in black with blacker blacks at the cost of having less dynamic range with burned highlights (false high contrast illusion, for a high contrast to be high you need details in shadow and highlights), and the worse thing you will find in any Amoled is PWM that is not present in the S7 LCD (point your cell camera in super slow motion to an Amoled screen and see what you get in any Amoled/Oled brand...), there is a reason why the specs of high end monitors says NO PWM, thus for a tablet is important not to have AMOLED if you don't want eye strain or other health issues as the time pass.
When I bought my Tab S7 was because of the LCD display, speed and audio output, last week I used it to sign a contract very well in the place of my turtle Onyx Boox Note (I don't use often the pen but is very responsive, the Onyx feels more like a paper but the screen is prone to scratches); I had Amoleds before in tablets and were horrible for my eyes and I don't like the burned highlights. I have been using the S7 for a month and I'm very happy with my choice and I use much less my S10+ (I hope Samsung will release smartphones with LCD and not curved screens...)
I don't see any reason why in a tablet someone should use Amoled.

Please stop telling people that amoled is god made. S6 screens are full of wobble. S4 and lower were oversaturated and settings couldn't be really changed. All "benifit" of amoled was there in saturation and non existent accuracy. Once saturation removed there was no real difference between lcd aside high propensity to burn depending on usage and blinking individual pixels. I am not saying that lcd is better but definitely not as much worse as you kije trying to shill about godlike amoled, but sung is always doesn't know what the hell they are doing. They doing whatever without understanding, everytime new variety of terrible obviously stupid decision.

If someone should consider color accuracy at all levels of brightness (Amoleds as the brighness goes up, the colors are totally off), dynamic range and health, LCDs with no PWM are by long much better than Oleds, the only advantage of Oleds are the deep blacks, lets wait for the minileds if they will have PWM or not.
By the way, all of my phones are and were amoled, my televisions are Oled and all have the nefarious PWM (LG say they don't but is a lie, I checked them with my camera) but I rarely watch them.
What about your laptop?... did you checked PWM before buying it or did you only check battery life, CPU and memory? Most of the laptops has tremendous PWM that is really bad to your eyes, but nobody is talking about this...
Why Apple and other brands put Amoled in their phones? because of consumerism, Samsung marketing (LG for Oled TVs) tried to convince hard the public for lot of years that the deep blacks is the way to go but they didn't explain at what cost including your health.
Tab s7 also has PWM according to notebookcheck review
