Display
With the Ascend Mate 7, Huawei introduces a JDI-manufactured IPS-Neo screen. The advantage of the IPS-Neo technology is that it provides better viewing angles and contrast ratio due to a change in the manufacturing process which allows for the the liquid crystal molecules to be uniformly aligned on the glass substrate.
Indeed, the viewing angles of the Mate 7 are much improved and I'd say it's one of the best in terms of LCD displays. Contrast ratio has also considerably gone up as we'll see in a bit.
The Mate 7 display offers lots of promise, but let's see if it holds up with our objective measurement tests. We use an X-Rite i1Pro 2 as our measurement hardware, in conjunction with SpectraCal's CalMAN software suite and our own workflow to be able to get an accurate display characterization.
The Mate 7 ends up at 484cd/m² in terms of brightness. It's plenty of bright for all but the most sunny days. Only direct sunlight reflectance may pose an issue.
In the black levels and respectively the contrast ratio is where we see the IPS-Neo screen perform extremely well. For an LCD screen, this is one of the deepest blacks I've come to meet in a device. The HTC One M7 seems to be the only other device to come near it, but that was at a lower brightness point with dynamic contrast.
The Mate 7 is able to achieve a 1750:1 contrast ratio, putting it at the top of the LCD pack. Only AMOLED displays are able to outperform this figure due to their ability to avoid any light emission on a per-pixel level.
In terms of colour temperature, the Mate 7 performs again quite well while hitting 6605K. This time Huawei seems to have aimed for 6500K instead of colder colours as on the Honor 6. If you still prefer the more colder and blue-dominated whites, Huawei as retained the colour temperature slider under the display settings which allows you to adjust the tone of the display to your own preference.
While the colour temperature figure seems to be quite good, under further investigation we see that there's a problem. Our grayscale accuracy test shows that there's much too much green at all grayscale levels. In fact, this is actually clearly visible on the device as we see a slight green tint. Gamma reaches an acceptable 2.11, still a bit off a perfect 2.2. Due to the green tint of the device the grayscale dE2000 ends up at 6.33, much worse than any device released in the last 18 months, and above the average perceivable threshold of 5.
Looking at the saturation accuracy graph, we see again an overabundance of green. It looks like the whole spectrum is pulled slightly towards green, which results in a whole offset of all measured colourpoints. This is a pity as the display seemed to be quite well calibrated in terms of saturation compression. The end result is that we end up with a meager dE2000 of 3.99. While this is much less worse than the grayscale measurements, it's not too bad, for example, it performs better than this year's G3.
Our Gretag MacBeth test is a measurement of accuracy of several commonly used colours. The Mate 7 ends up with a respectable dE2000 of 3.88 here. We again find that the score is merely thwarted by the green-shift of the display, prohibiting this display to enter the group of outright excellently calibrated devices such Samsung's and Apple's newest models.

Awesome phone, awesome battery life, fast processor especially in gaming. great screen, a bit low on brightness but not too bad. 6" feels good on one hand use that you actually forget it's that big. Fingerprint scanner is great, works very well. The camera is really good, surprisingly so.While software is eye candy (which i personally am a fan of) and offers more functionality than standard Android (A lot of functionality, the little things that make it a joy to use), it is a bit buggy. EMUI 3.0 looks good, like a cross breed between iOS and Android and i love that, however, it tends to reset to default settings on some applications kinda like forcing you to stick with EMUI's default apps, like the launcher, Messaging app, phone app, music app, etc. (this can be really annoying at times, but it is controllable).
Another thing is, and this is really strange, EMUI doesn't allow other 3rd party apps to gain access to the phone's "notification access", e.g. lockscreen apps. the functionality simply doesn't work, so you end up being forced to use only EMUI's native lockcreen, which by the way is the only lockscreen that works with the fingerprint scanner, meaning if other 3rd party lockscreen apps could actually work, they’d still not work with the fingerprint scanner. make sense?
So to sum it all up... phone hardware is superb and the internals are beastly too, especially battery life, in fact best in class. It also feels and looks expensive and premium. software is a joy to look at, really eye-candy, the little things like installing apk's, checking for software updates, the shutdown screen, all look visually pleasing, even uninstalling a app looks and feels like a beautiful process. However, if you like to customise Android, then the software experience could prove to be a little bit frustrating but nothing over the edge. And since it’s software, Huawei can fix it with an update. This is a good phone.

I'm a big advocate of Samsung Note series. However I have been using Mate 7 since the first launch...because the price was much cheaper, and I found the specs to be better (160GB, sensors, larger screen, brighter screen and a more intuitive UI) and have been using it to test games. So far I am impressed by the solid build, as I have dropped the phone many times and the screen barely has a scratch. Small dents in the frame but none too noticeable. It's been a year, and I find the phone to have been quite stable. I look forward to the next series.
