With the rise of smartphones and tablets, the display has become one of the most important aspects of a mobile device as it’s the primary mode of interaction. However, throughout computing the display has generally had relatively little attention. People might have talked about resolution, size, and latency, but the discourse was vague at best. In order to really understand displays, it’s important to discuss a number of factors that affect display quality and the underlying design of the display. These factors range from subpixel arrangement to TFT structure and various emitter materials. With traditional reviewing methods, it’s often difficult to say one way or another whether one display is “better” than another. While simple metrics like maximum brightness can be compared in a relative manner, it’s hard to say whether one has better colors or higher static contrast. In order to test these metrics, we turn to objective measurements from devices like X-Rite’s i1Pro2 spectrophotometer and i1Display Pro colorimeter. In order to acquire the data from these devices and present it in a usable manner, we use SpectraCal’s CalMAN 5 with a custom workflow.

Under the microscope and based upon some quick viewing angle tests, subjectively the Galaxy Note5 display looks and feels like a bigger version of the Galaxy S6 display. Viewing angles for some angles feels like the display is almost painted on to the glass below, but some odd interference effects with viewing angle changes breaks the illusion to some extent. In the case of the S6 edge+, the curved edges of the display cause a noticeable shift in luminance when looking at the edge compared to the center of the display, which also causes an odd green shift which is probably due to the RGBG subpixel layout. I suspect the best LCDs will still be better at the “painted to the glass” illusion for the near future. This isn’t a huge deal, but it is a noticeable difference.

Display - Max Brightness

Moving on to our brightness testing, we can see that the Galaxy Note5 delivers a healthy improvement over the Galaxy Note 4 generation of AMOLED, but it isn’t quite at the same level as the Galaxy S6. It isn’t clear why this is the case, but I suspect this is related to longevity and other concerns outside of brightness. Meanwhile the use of OLED means that black levels are perfect and contrast remains solely determined by the lighting of the room and the reflectance of the display, which is similar to most other smartphones.

Display - White Point

Display - Grayscale Accuracy

In our standard grayscale testing, the Note5 delivers acceptable color accuracy but it seems that the Basic screen mode tends towards a warm color balance. I suspect this helps with power efficiency, as blue in general requires more power to achieve the same level of luminance. Other than this slightly warm white balance, the grayscale accuracy doesn’t have any significant errors. This means accuracy ends up very good - certainly below our threshold for noticable errors - especially in comparison to the Galaxy Note 4 which had some noticeable problems with green tint on some units.

Display - Saturation Accuracy

In our saturation test, Samsung does well enough that there’s really nothing to talk about because there's so little wrong here. You could argue that magenta is a bit warm on our review unit, but the difference is too small to be worth talking about. Error on average is going to be hard to spot unless you have a flawless reference monitor to compare against.

Display - GMB Accuracy

In the GMB ColorChecker test, Samsung continues to show a strong performance when looking at various hues that are commonly found in consumer content such as movies and camera photos. There’s a slight red shift on some of the tested hues, but the error is so minor I don’t notice that any problems here.

Overall, the Galaxy Note5 and Galaxy S6 edge+ both have an incredible display. The Galaxy S6 edge+ does have some problems with viewing angle shifts by virtue of the curved display, but this is effectively unavoidable given the subpixel layout and the radius of curvature. With this generation of AMOLED, Samsung has definitely equaled the best LCDs on the market. I suspect within the next year or two it will be inevitable that Samsung AMOLED will be clearly superior to even the best LCDs. However, without other OLED suppliers that can provide similar quality and cost I suspect OEM adoption will continue to be limited.

    Samsung lost me the second they announced they weren't releasing the note 5 in Europe. I hope they get enough of a dent in their sales from annoyed customers that they release the note 6 here after. I have a feeling that's wishful thinking though.

    Excellent review as always Joshua never mind the brand wars in the comments. I was always an iOS user and thought Galaxy Note 5 is a good enough device to jump the ship for the terms of a contract. While I am reasonably happy with the device, I still think Software is Samsung's biggest issue.

    I also noticed an issue with the S-Pen sensitivity where it does not work at all at the bottom left and right corners of the device. This means that if I need to take a screenshot which goes right until the bottom right or left corner I cannot do it because the sensitivity simply vanishes. Also attaching a video to exactly show what the issue is. Can you check if your device also exhibits the same behaviour.

    Samsung relied too much on Exynos 7420 this year. The Note 5 is supposed to be a huge improvement and their better phone from the S6 which is already considered kinda old in the tech world. It's all the same tech just later in the year. Yawn. The iPhone 6s technology just obliterates this phone. Good luck Samsung, you're going to need it

    Exynos 8890 is on ready dude

    Single core and most likely graphics performance won't match A9. I read a 45% increase in CPU performance that puts it under 2000 geekbench still.

    At first I was sad to see that neither of these included a microSD slot. That would be an awful omission on devices extremely well fitted to media consumption. That would rule them out of my consideration. But the photos made me wonder, so I looked further and found the slot mentioned in the middle of the review.

    Really... I know it is AT's sworn position that microSD is useless, irrelevant and obsolete... but how could you not even list it in the spec table? Just for those of us who continue to be deluded by our daily use of it. I never cease to wonder at the time and effort spent on describing case colors, and the blindness to important functional features.

    The S6, S6 edge, S6 edge+ und Note 5 DO NOT have a microSD slot.
  • Arbie - Saturday, October 3, 2015 - link

    Then these sentences are grammatically broken (wrong tense throughout): "The back cover is faux-leather plastic that peels off much like the Galaxy S2's back cover, with a removable battery and microSD slot. The display has the same buttons, but the bezel had a striped design for unknown reasons." As written this refers to the new devices, not the old ones!

    I won't even consider a device of this screen size without microSD. A read-only implementation would be fine (satisfying Android security needs).
  • Devo2007 - Sunday, October 4, 2015 - link

    Those sentences shouldn't even be in this review. Definitely confusing
  • Dobson123 - Sunday, October 4, 2015 - link

    They're about the Note 4.
