How big is the screen on the + compared to a 16:9 phone? - Samsung Galaxy S8+ Questions & Answers

I know this is a silly question and I should be able to figure it out on my own but my american public school education is not all that great. So if you took the same screen width of the S8+ and calculated it, how big would the screen be if it was 16:9? Just going by width it seems like it should be the same size as the Note 7.

just find the area of both screen ratios at their respective sizes (L*W)= A

Math
The area on the 6.2inch display of the s8+ is 97.56 cm². That is comparable to a 5.95inch display with 16:9 proportions.
Actually, not really trivial to calculate, since you don't know the exact display measurements. Here is how to do it:
What you know: Display diagonal =6.2inch, height to width proportions, h/w= 18.5/9.
You set x to be one proportion, so you have: height=18.5x, width=9x.
Now, since the diagonal of the screen is the hypotenuse, you can use the Pythagorean theorem to calculate the width and height. You have something like:
a² + b² = c², with c being your diagonal (15.748 cm=6.2inch*2.54), a and b being your height and width respectively.
So, you have the following equation:
18.5²x² + 9²x²=15.748²
You solve it for x to get: x=sqrt(15.748²/(18.5²+9²)). Now, you figure out your height and width by just multiplying this expression with the given proportions:
height=18.5*sqrt(15.748²/(18.5²+9²)); and width=9*sqrt(15.748²/(18.5²+9²)). I use the expression, because you can use excel to just calculate it for you.
The result will be height=14.16cm, width= 6.89cm. Then you multiply them together to get the area, which is then: area=97.56. Now you know the display area of your s8+.
Now, you want to find out what's the display diagonal, that will have a similar area given a display proportions of 16:9. You set one part of the proportions again to x, and then your height will be (similar to above) 16x and width will be 9x. Since you know the area, you just multiply them, to get the equation:
16x*9x=97.56 => 144x²=97.56 => x²=97.56/144= x=sqrt(97.56/(9*16))=0.8231, multiply by given proportions to get heigh=13.17cm and width=7.41cm.
Now, we use the Pythagorean theorem again to get the diagonal: diagonal = sqrt(13.17²+7.41²)=15.111 (cm). You divide it by 2.54 to get your beloved (and damned) inches: 15.111/2.54=5.949inch.

I would hit Thanks on your post, but you kill Iris West in the future. I don't like you.

I think @Savitar 's answer is correct in terms of perceived size but does not answer OP's question, which was the diagonal size of a same-width phone (ie the diagonal of a 16:9 cropped video showing on the screen of the S8+, which is quite smaller)
Using similar techniques to the original answer, the S8+'s screen width is 6.82cm, which gives a 16:9-cropped height of 12.12cm, and a 16:9-diagonal of 13.9cm -> 5.5 inches, just like the galaxy S7 edge!
In case you were wondering, the regular S8 has a screen width of 6.38cm, a 16:9-cropped screen height of 11.34cm and a 16:9-diagonal of 13.0cm -> 5.2 inches (almost) like the galaxy S7!
So basically that's why the phones are so similar in dimensions to the S7/S7E, they managed to reduce the top and bottom bezels a lot while keeping roughly the same width!

This is the info i'm looking for, thanks

I guess it depends on which 16:9 phone you're comparing it to.

Almost makes me want to wait for the Note 8. There was a sketch leaked of the Note 8, and as usual the Note display layout was superior to the S series display. The Note 7 was far nicer in display and display curve than the S7 for instance. I expect the same to hold true if/when the Note 8 comes out.

What's left to do on the Note8's display design wise that hasn't been done on the S8's? The edges are already as tightly turned as the Note7's. The display is already 93% of the face of the phone. Display feature wise I could see it being Samsung's first 4K display which would be great for VR. I could also see some more width being added to accommodate the S Pen silo which would increase the diagonal measurement of the display making it larger. Other than that it's hard to imagine where else Samsung can take the Note8's display. I'm buying my S8+ outright so I can sell it to get the Note8 when it comes out but I'm not expecting huge gains in the display or features over the S8. I just want S Pen/S Note back. My short time use of an S7 Edge and S8 are just detours I was forced to take after I moved off my Note5 to the now deceased Note7.

Goddamm
I'm sending my kids to Russia for schooling.

display confusion!

I want to know what is the benefit of vga screen over qvga screen in term of readability (messages, pdfs, ppts, ebooks etc), surfing (internet) etc and in videos?
secondly what is better, a vga with 65K colors or qvga with 16M colors?
and how much screen size effect the sharpness of display? like 2.8" vs 3.2" with same color depth and resolution.
1. Many VGA screens are bigger than QVGA, so for example e-books will be easier to read. However, if screen sizes are the same, it'll only be sharper. If you zoom in in Opera, it will zoom in enough to see the letters for QVGA. Only for VGa, you will see sharper edges of the letters.
2. That's a bit subjective. VGA = sharper, QVGA = clearer. Gradienst will show up better, but you see the pixels more.
3. If you're using a VGA or WVGA device, it will be hardly noticable.
But the difference in QVGA will be more I think.

Look at this image, if you were talking about this image (the second one aggregated by Google), than I hope you understand that the screen on the left of the picture is qVGA and that the screen on the right of the picture is VGA.
There is a difference between readability and screen resolution.
The font on the left PDA might make you think that the font is readable, but that is only because the the page is zoomed. The font on the right PDA seems to be unreadable because the page is zoomed out.
But if you were to have the same zoom settings on both PDA's (for instance, the PDA on the left is zoomed as much as the one on the right), you will notice that the PDA on the right is actually more readable than the one the left.
The next image below makes more sense:
http://bp3.blogger.com/_NPv_nmIu1M4...ga-qvga-screen-comparison-mobilyazilar-cr.jpg
In this image, you are comparing the screens of an Dell Axim and an HP iPAQ. This time, you actually see the same exact thing with the same exact information with the same exact zooming ratio. The only difference is that the software displays the data a little bit differently. You know that everything is equally proportioned because of font size, arrow position and length, and the approximate size of the boxes. Apparently, the device with VGA resolution has smoother and less pixelated fonts, and they are therefore more readable.
Basically a quarter of a VGA only display a quarter of it, so you see less information, which means less pixels to smooth out the lines.
thanks man for clearing it more. Now I going to ask a 2.8" VGA screen specific question like htc touch diamond etc. Is this size good for surfing and reading or I should go for larger screen like 3.2" or even 3.8"?
Can a 2.8" vga screen display a full web page without horizontal scrolling?

You're welcome. It's somewhat hard to fully understand it without actually having two phones with extremely different resolutions.
Okay a 2.8 inch screen is quite readable for small fonts if the resolution is 640x480 (VGA). However, you will NEVER be able to go full screen (the font will be smooth but to small to read).
Surfing the web on a PPC phone or smartphone isn't that fun unless you have capacitive technology with 3.5 inches or more.
I prefer not because my standard is to buy the best of the best and the largest device with the best resolution. So of course I am partial, but at-least I don't put limits to what device I want to buy.
Do you have any idea how big a web page is? It's very big, they will almost always NEVER be able to fit on a 2.8 inch VGA screen.
It wont even fit a 4.3 inch wVGA screen (800x480) on the HTC HD2. There will be some horizontal scrolling but it will like only an inch away. The problem is that the fonts will be very small and not very readable.
But if you zoom a bit, then browsing is a breeze.
I hope you know that not even a laptop computer's browser can display a full page without having the fonts reduced to little ants.
I have uploaded an image, you will need to download the attachment below. This image shows you that not even a laptop screen can display an entire web page without the cost of 100% unreadability. Here is a link to the actual web-page http://www.thefreedictionary.com/. Compare what you see in this link, to the picture in which I zoomed out to view the entire page. Don't use the browser viewer to view the image, save the image so you can view the image in full screen and fully understand that it is truly unreadable NO MATTER WHAT.
thanks again man. What capicitative screen makes diffrences?

Green line of pixels down left hand side

I've noticed that on the very left hand side on the edge of the Captivate that there's a column of green pixels going down the whole screen. It looks to be about 1 pixel wide. For me it's most noticeable when you pull down the drop down menu.
I don't know if it's normal or what. I exchanged it at my AT&T store and got a new one, and the new phone also had that column of green pixels on the left hand side.
Any one else notice or have this problem? Is it normal?
I do not have this on mine...sounds like a good reason to take it back and get a replacement..
I took it back yesterday and got a replacement, but it still had that green line. While I was there I looked at all the other display models and every single one also had that problem.
Anyone else? Or is it just that certain AT&T store lol
I can only reproduce this effect with the drop down notification menu and nothing else. Try pulling the menu down on a black screen or by looking at the area where the notification bar and menu meet and you'll see that only the drop down is affected.
its norm, if you browse a completely white page in explorer you'll see it there too. If anyone is worried about it, its deff not noticeable and i have severe ocd issues.
This is normal of any Pentile display such as the one found on the Samsung Captivate. It is not an issue.

Hahaha. +1!
But yeah, that's just how the led's are aligned in the display. Completely normal.
Here's some more information for those curious about Pentile Matrix's. This infomation predates the actual manufature of Pentile matrix's, and explains why it is used over a traditional grid matrix. Enjoy!
"This is a color subpixel-rendering system that promises to improve LCD resolution significantly, while reducing data driver requirements. The PenTile Matrix by ClairVoyante (Sebastopol, CA) doubles the addressable resolution in each axis and the modulation transfer function.
An LCD differs little in basic concept from a stained-glass window, modulating the light that shines through it to create a color image for the viewer. The need to generate a moving image, however, requires that the image elements be as small as possible, yet arrayed to blend subpixels in close proximity to properly represent colors.
In the PenTile Matrix, each color is surrounded by the other two colors, using a pattern of alternating red and green pixels to carry the logical pixel information. The blue pixels provide only low-resolution chroma information, matching human vision characteristics, while significantly reducing the number of data drivers. The light intensity is regulated by white subpixels (a recent innovation being explored by other display configurations and technologies as well).
Conventional color LCDs use three subpixels--red, green, and blue--in vertical stripes. A principal disadvantage of the arrangement is that it relies on the blue pixel to carry high-resolution luminance information--a difficult task because of limitations in human vision.
Subpixel font rendering on the RGB stripe is limited to increasing the addressability by a factor of 2, while the PenTile Matrix can double that number in both the horizontal and vertical axes for a fourfold improvement. Another advantage is that the arrangement is nearly rotationally symmetrical, allowing the display to be rotated more easily for portable devices and other displays that may be viewed from different orientations based on the information displayed.
There are currently no displays using this matrix available, but Samsung is working on some prototypes for possible release in 2005/6."
And now for the Wikipedia link to additional more recent information: http://en.wikipedia.org/wiki/PenTile
And another link: http://www.displayblog.com/2009/04/16/samsung-oled-pentile-matrix-why-is-the-red-sub-pixel-so-big/
I've tried looking for this and really dont see it. I see what may look like one line of green pixels all the way on the left as you slide down the notification area. But I basically have to tilt the phone and look inside that area.
I see it. Its pretty damn small though lol.
The green line is only noticeable against brighter background when the green subpixel is being used to trick the eye into seeing white, etc. For example, my background is mostly darker colors, but where an area of white touches the edge of the screen, the green line appears; but only next to the brighter colors, not the darker ones. Kind of weird now that I look at it lol
This makes me feel a lot better that the screen is that way. I just wasn't sure if it was normal or not.
Thanks for clarifying!

Funny, since reading this thread last night, I do now notice that one really thin green line running down the leftmost edge of the screen on certain occasions. Its got to be caused by the pentile matrix arrangement of pixels. That first entire left row is all green, thats whats doing it. Especially when you're on a black background like when you slide the notification area down.

[Article] cellphones and photography

Hi all!
All ok?!
I create this small text for a Brazilian Android Forum, called BrasilDroid, so I would put here in XDA too.
It is about the quality of our cellphones cameras and the quality of them.
A lot of definitions :
What is Photography ?
Literaly is write with light. The term is derived from Greek. photos(light) and graphos (drawing). So, the basic premise for take a picture is... Light!
What we need to take a photo?
For take a picture we need a camera with lens and film, that in digital photography is the camera sensor.
Pixel and Resolution
If we make a enlarge expansion in a photo we see various square points that make the image, this points are called Pixel. This is the minor measure that we have in our photos.
The photo resolution are directy connected to the Pixel. In a photo that have dimensions of 1920x1080 your resolution is 2,736,800 px or 2.1mpx.
Roughly, resolution is the photo area.
Quality vs Pixel
Many peoples confuse the camera quality with the amount of megapixel available.
But, quality not linked with quantity.
The Camera quality is linked direct to height of sensor and how the sensor handles the lack of light.
When we pont our camera for the scene and shoot a "curten" open and leave the sensor exposed to light. In this moment the sensor catch the light. Immediately after the "curten" close and the image is recorded.
While the obturator(the name of "curten") is open the sensor is capturing the light, so, smaller the area for capture minus details can be captured and more digital interference need to be used to create the image.
Let us consider two sensors:
Sensor 1 - 7x5mm.
Sensor 2 - 20x14mm.
These sensors be in two diferents cameras with 5mpx of resolution.
When we take a photo in 1920x1080 (Full HD) the sensor try capture the light of all scene usin 2.1 milions of points.
In First Sensor the pixel be very close, the area is smaller, making the size of these pixel be small, soon, the amount of detail that each of these pixels will be store are small.
In Second Sensor the pixels be more separated, the area is bigger, the pixels can capture mor information of the light.
The final image will be the same resolution in each sensors, but, the sensor two store more information. Considering the size of this sensors, Sensor two will store three times more information.
In other words, a small sensor need perform a big effort for store all information, are many pixels in a small area. This makes the camera need interfere in capture, generating small points between the pixels. In these moment we have other problem ... Grain...
So, for what serve the pixel ?
Enlarge.
The more megapixel used in a photo greater be your dimension, so, more we can enlarge the picture keeping the proportion without loose information.
Why the photos look better on cellphone than on the computer?
That we see in screen of cell is basically a photo in a lower resolution than the real resolution, these lower resolution hide photos imperfections and some LCDs can make a bigger shine or contrast in the photos, like the AMOLED.
How to take better photos with cell ?
1 - Don't use the max megapixel
If you are shoot with cell, certainly, be a big image don't is your objective, so, you can take photos in small resolution. In Cell with 5.0mpx take a picture with 3.2mpx only bring gain...
2 - ISO
If the camera have manual ISO, try to use the lower ISO number, the higher ISO more digital inteference, and more grain...
But, the low ISO makes the scene need more light.
3 - Prefer shooting statics objects or don't shake
Most of cellphones don't allows the manual configuration of Obturator Speed. The camera software try to choice the better speed for the scene.
The phone try balance the speed with ISO and aperture, many times the speed is going down. And slow speed is synonymous of blur photo.
How to get around this? If possible, increase the ISO or increase the exposure compensation. And let the phone as still as possible.
4 - Using flash
Flash, very polemic, but, in cell cameras can be a great ally.
When use the flash your light make that the scene freeze, reducing very much the slow speed problem.
Obvious, xeon flash is better than Led.
5 - Modify the pr proportion
Case the camera be proportion adjust try choice the best of each photo.
Proportion 4:3 = 1.333
Proportion 3:2 = 1.5
Proportion 16:9 = 1.77
To calculate the proportion just divide the bigger side by smaller.
Para calcular a proporção é só dividir o lado maior pelo lado menor.
A Photo with 2048x1536 px be : 2048 / 1536 ~= 1.333
So, the resolution 2048x1536 have proportion 4:3.
To improve the photos working with the proportion the best way is using photo's editors.

Iphone and S3
(https://forum.lowyat.net/topic/2708421/+200)
They noted that the lower sensor of a digital camera 1/2.5 (0.4) is ~ 25% higher than the sensor of Galaxy S3 1/3.2 (0.31)?
Guys, it is clear that we can take great pictures with our cell phones, however, the limitation of the hardware and the sensor will always do that to that quality is not expected.
After all that, you imagine how absurd it is to have a mobile phone with 41mpx resolution?
A decent camera, that resolution costs over $ 20,000 and has a huge sensor, called medium format!
I propose a challenge. I take two pictures with my Ace 2. One with 5.0mpx and other with 3.2mpx. Both are in the ratio 4:3 with 100% Crop.
which of the photos was made ​​with 5.0mpx and what was done with 3.2mpx?

This Is How You Are Cheated by "Professional" Reviewers Over Display

I was trying several mobile phones these days and got interested in displays. The following is what i've learned from my experiences plus online information:
It is a very easy work to tell the quality of a display, whether it is equipped on a TV or computer, or a smartphone. Just start up the device, have a look at the user interface, and you’ll get a rough impression, which, in most cases, is true to truth in the end. But there is always someone playing tricks to convince you that his display, which is not good in fact, is good, especially on the Internet.
While most people may not trust advertising maps made by CorelDraw or perfected by Photoshop, reviews do have influence on their choices. If you are going to buy a cheap phone from China, online reviews may be the only path for consultations. Unfortunately, neither all customer reviews come from real customers, nor all professional reviewers tell the whole truth.
For example, two phones with different display resolutions don’t look too different in a photo taken beyond a certain distance. Resolution, such as 1280x720 pixels, means the number of color points (pixels) that compose an image. The more pixels, the more details of a picture are shown, but when the distance between your eyes and the screen is long, the details are not so distinguishable. In most cases, we use mobile phones in a close distance.
A little theoretical? OK, I’ll compare two phones of the same 5-inch screen size but different resolutions for demonstration, namely, Axgio Neon N1 with 1280 x 720 display (HD or 720p) and THL T6S with 854x480 (480P).
I downloaded a 1920x1080 (Full HD or 1080P) picture from the Web and put its copies into both the two phones aforementioned. It’s hard to see how the Neon N1 has better performance than T6S in the first photo when my camera was held a little far from them. But in the second photo, the grass is sharp on Axgio Neon N1’s HD display, while it is a mass on THL T6S.

Well, apart from grass, there are some scenes with smooth surface to obscure the gap between high and low resolutions even in close look, such as the sea. Smooth surface means that the colors of neighboring pixels are very similar or the same, thus the reduction in pixels may not affect the visual impressions very much.
But believe me, your eyes are more sensitive than cameras to such changes, which can be better defined in macro photos. Now you can see that the Neon N1’s 720P display has high integrity while there is mosaic with the T6S’ 480P resolution.
An HD display has about 900 thousand pixels ( 1,280x720=921,600), while a 480P display has only 400 thousand. Apparently, pixels are one time more closely arranged on a 720p display, where it’s not very easy to distinguish one pixel from others. On the other hand, there is no doubt that 480P or 540P (QHD, 960x540) screens deliver granules to your eyes in daily use.
Macro photos may be the best way to show display quality in the aspect of sharpness. For example, displays with the same face-value resolution may have varied performance in practice, while a responsible reviewer may use macro photos to make the disparity visible.
OK, let me add a 1080P display from Huawei Honor 6 before my close-up lens for a conclusion: 480P and QHD, with obvious granules; 720P HD, smooth; 1080P FHD, impressive.
I didn’t mean to say THL T6S was equipped with a bad display. On the contrary, it performs quite well at its native resolution among Chinese phones, just like Axgio Neon N1 and Huawei Honor 6.
Besides real resolution, another factor that concerns users is color. If you ever got interested in photography, you would know that color is highly vulnerable to camera settings. If a professional reviewer modifies settings to enhance contrast or saturation, it’s impossible for ordinary consumers to discern that.
But if someone plays the comparative trick, there is a way to tell. We know that no display can avoid color shift when it is viewed in an acute angle, and it’s where a dishonest reviewer can deceive consumers. He may let his camera and desktop form an acute angle, put a well-reputed phone at the far end, place an advertised phone in the center of the scene, and then shoot a picture showing the false impression that his phone is as good as or even better than the real excellent one.
I’ll still use two Chinese phones to demonstrate the trick. In the first photo, when Axgio Neon N1 was located in a bad place, it looks worse than Cubot X6 (720P display, too). But when my view angle is vertical to the desktop, you can see that the N1 is truer to life.
Again, I appeal that all professional review sites should use macro photos to show display colors, because in such a distance, color shift can be neglected.

Hello MIUIers,
Ghost image or screen/image burn-in are names given to a permanent discoloration of your smartphone’s screen caused by irregular pixel usage. The prolonged use of static images can create a permanent shadow or ghost of that image on the screen. This problem is more common than you think, and happens most often on AMOLED screens (although LCD displays aren’t completely free of this bug). Fortunately, there is a solution to restore the image quality of your device.
The screen ghost happens when phosphor compounds that emit light to produce images lose their intensity with prolonged use. Moreover, the irregular use can "burn" an image onto the screen which will be visible all the time. Many apps which are available in the Play Store promise to reduce or even stop the problem. One is the Screen Burn-in Tool.
The concept is simple: a sequence of primary colors is displayed on your device, restoring the "burnt" pixels. In fact, this was the original function of computer screen-savers: one dynamic image that appears when the screen is idle to makes the pixels "exercise" and ensure that the same area of display doesn’t remain constantly illuminated.

Do it at your own risk!
Today I will teach you how to remove the famous burn.
White 80%
Blue 80%:
Green 90%:
Red 100%:
I can not guarantee it will work on other models, my cell phone had very strong shadows on the screen, I realize that almost everything has disappeared ... I'm still running the program, I'll keep you informed on this subject!
Yes, it works, although some report that this does not happen, but their effectiveness depends a lot on the severity of the recording.
If you have shadows from a keyboard or square or both you can remove everything or almost everything, I have the program running for a week at night, I restart the cell phone in the morning and normal use.
Download the Liquid Burn-in Wiper application and use one or four weeks at maximum brightness.
Restart the device once a day, you will have with some luck recovered 80% to 99% of the screen with shade or burn.
Mine at the moment recovered 80%.
Soon I will update the topic with new photos, please wait.
Update add apk:
LCD Burn in Wiper v6.1
OLED Tools v1.3

the post is solely to help people who have burns on the screen and do not know what to do.
an admin must've moved your thread.
Is this the same app as LCD Burn-in Wiper 6.1 by AVAWorks on playstore?

Not saying it doesn't work, but an app targeted at AMOLED screens should be your first port of call...

If you even repair the ones that say it is for OLED screen they use the basic color system (rgb) ... then any application that changes the default colors should work normal.
Yes, my friend, I do not know why they said no.
do the test yourself, let it run for a week and you will see the difference.
As soon as I finish the tests I will post new photos.
Doesnt it just burn the rest screen out to even it out?

The rest screen is toprevent it from appearing.
You can use it, but it will take much longer, since we do not have a refresh of colors quickly and evenly.
If you want to contribute to the community, you can do some tests. :good:

I think what he meant was:
Does it work by burning the not-already burnt out parts to make it appear less burnt out?
I have Galaxy S5 that has pretty noticeable burn-in. When I view completely white image I can see bright white bars at the top and bottom of the screen, top bar even has few icons visible such as warning triangle at the left, i (info) and home at the right so apparently previous owner was using a lot of some kind of web browser at high brightness levels. Center of the screen is slightly dimmer and yellowish so I assume pixels have been burnt more there.
Now I have read about this AMOLED problem and as far as I know you indeed need to burn better pixels causing the ghost image to same level with the rest of the pixels to make ghost image disappear. I planned to try treating the lower ghost bar first and I already created black image same shape as the screen (but a little larger) having white bar at the bottom. I can view this image on my phone, zoom in and align the white bar to match the white bar of the ghost image while the rest of the screen is black. Then turn brightness all the way up and hope that pixels at the bottom of the screen wear out enough and ghost bar disappears. But I guess it'll take very long time. I'll try few hours per day for a week and see if it makes any difference compared to top ghost bar.
It's very difficult to align the image so that it's pixel perfect so there might be a chance that line or two of the brighter screen portion is covered by black area of the image. But I suppose having slightly brighter 1-2 pixel wide line across the screen is better than noticeably brighter large section of the screen.
I have been keeping the better pixels on at full brightness for total of 24 hours now and I can't see any difference. To me it seems that fixing amoled burn-in isn't a quick process but needs tens or hundreds of hours of screen burning to wear better pixels down to same level so that ghost image disappears. And that's pretty logical as burn-in itself doesn't occur overnight but during months of phone usage. Maybe I'll leave it as it is, my eyes have gotten somewhat used to it anyway. Not worth the trouble.
