Software - EmotionUI 4.0

The Mate 8 is the first Huawei device to ship with Android 6.0 Marshmallow. As in the past, Huawei tries to improve and differentiate from stock Android by including a customized UI that tries to introduce some larger UI changes as well as functionality. The newest iteration of Huawei’s skin, called EmotionUI, reaches version 4.0 and is an evolution of EmotionUI 3.1 that we’ve seen on the P8 and Mate S.

 

 

In terms of design we see a continuation of a frosted translucent black notification shade and quick-settings drop-down panels. Here we didn’t see much change compared to EmotionUI 3.1. I appreciated the look that was introduced on the P8 and as such don’t see much need to change what is otherwise a clean interface.

I did notice that Huawei changed the drop-down behaviour when swiping down the notification shade; in the past you’d have to swipe down with two fingers to get to the quick-settings view, while one finger swipe naturally opened up the notification view. The difference in behaviour now is that when you don’t have any notifications available, a one finger swipe will open up the quick settings panel instead of the notification shade, a change that made sense to me and I somehow appreciated with continuous usage.

An extremely large improvement and change to a nagging UI choice in EmotionUI 3.x is the task switcher. Huawei has thankfully abandoned the 4-tile paginated preview UI in favour of a more stock-ish continuous scrolling linear layout. The difference here is that instead of having vertically stacked previews of the apps, we see full-screen previews that are arranged horizontally. This allows Huawei to still keep the gestures (swiping down on a preview) for “locking” an app from being killed by memory management. Swiping up will still kill the application.

The video above was recorded via the system built-in recording function. Beyond the already existing option to draw letters or figures with your knuckle and bind them to shortcuts to applications, Huawei introduced the option to take a screenshot with a double-tap with one knuckle, or to trigger video recording with a double-tap with two knuckles. The resulting video format is 720p at 18fps with a bitrate of 2.7Mbps, which is not quite of the best quality but at least serves its function and is storage friendly.

On past year’s devices I mentioned that the overzealous power manager’s (Power Usage Firewall) default settings resulted in a lot of warning notifications of power-hungry apps running in the background. On EmotionUI 4.0 I haven’t seen a single such warning as it seems Huawei has greatly toned down the default warning thresholds. Unless an application is “locked” or protected via the task manager interface, the system kills applications once the device is suspended, even if they acquire wake-locks. The feature that can be positive to disarm badly designed applications which might drain battery life in the background, but definitely needs to getting used to when coming from other Android implementations following the default memory management behaviour.

 

Further large UI changes can be found in the settings page where Huawei has drastically cut down on the amount of items in the main settings view, rearranging a lot of the usual configuration categories in sub-menus. The “Advanced settings” sub-menu has become a collection of the least accessed settings, which oddly enough also now includes the Battery Manager page which further also hides the classic “Consumption level” page in a further sub-menu. Android’s battery consumption statistics are just estimates than are often very inaccurate so I’m glad that Huawei buried the misleading numbers away from the average user, but I still would have liked to see at least a more accessible device battery lifetime and screen-on time statistic at higher level somewhere in the settings.

 

 
Large vs small view mode

Because the Mate series and phablets in general come with such large displays I’m always disappointed to see manufacturers not actually take advantage of the screen estate and ship the devices with an appropriate UI density that allows for more content on a given screen area. This was a problem for the Mate 7 and something that I also immediately picked up on on the Mate 8.

Thankfully a new feature of EmotionUI 4.0 is the ability to change the system’s global DPI settings. Found under the display settings, the “View mode” page allows to choose between three different density settings that scale all interface elements system-wide. Changing the setting requires a reboot for it to take effect. At the highest density the Mate 8’s UI elements are roughly the same size as found on the Nexus 6P, but with the advantage of having a larger screen area. Looking back at the Mate S I now realize that it’s something I didn’t pick up on while reviewing the phone, and Huawei’s past device would definitely benefit from higher density interfaces and inclusion of this new feature. I would more than welcome other vendors to include configurable DPI settings as it can greatly improve a device’s screen experience, which is by the way also something that isn’t solely limited to large screen devices.

 

In terms of system applications there hasn’t been much change in EmotionUI 4.0. All default apps are very functional and work well. The Mate 8 hasn’t lost any of the additional features that were introduced with past devices and that’s not a negative thing either. Even though themes are available, they are just able to change icon packs and colour accents in applications. There is still a lot of white in the UI of the system apps, something we saw introduced in Huawei’s larger UI overhaul in EmotionUI 3.0. It may have been interesting to see a switch to the more modern navigation and button schemes that were introduced with Android 5.0.

One particular design choice that still doesn’t go well with me personally is the default launcher and the normalized icon frames that try to mimic iOS’s style. This together with the fact that there is no application drawer inclines me to quickly drop the stock launcher in favour of a third-party one, which thankfully is an option and works without any issues.

 

I’ve liked EmotionUI in past reviews and the Mate 8 is able to make some evolutionary improvements that is able to fix some of the more outstanding critique points found in past devices. I’m definitely happy that Huawei finally changed the multi-tasking UI as it makes for much more fluid and ergonomic usage, something which was definitely a problem with last year’s Mate 7 and to a lesser extent smaller form-factor devices such as the P8.

In terms of performance Huawei and particularly HiSilicon seem to have made very large improvement to the Android codebase. This was one of the talking points during HiSilicon’s presentation of the Kirin 950 and how the new BSP software improves on things such as touch latency and application launch time. This seems to have very visible and immediately noticeable results as the Mate 8 is by far the fastest Android device I’ve come to use to date. When turning off all system animations it becomes visible that when switching between applications the Mate 8 is able to respond much faster than for example the Nexus 6P or Galaxy Note 5.

All in all the Mate 8’s software is very good. Any subjective design elements such as the launcher are replaceable, while the rest of the UI is clean and attractive, although one can still fine some older design elements related to the system applications. It’s definitely in regards to performance that Huawei was able to impress as it’s something I didn’t expect at all and actually puts the performance of other Android devices in perspective, so I hope Google and other vendors are closely paying attention to the improvements made on the Mate 8.

    Problem with ipones is that prices DOESN'T go down quickly.. For this Mate 8 it will soon be cheaper .. Mate 7 released in october or november 2014 and in december I bought it just for £300 on ebay
    So it will be the same with mate 8 but forget iphone 6s to be cheap man..

    Haha they say the same about Huawei in China, except they meant it the other way around, "prices go down so slow so Huawei must be good~ look at that crappy Samsung that drops 1/3 of its price in a few months~" Reply

    it is quite a bit cheaper, your $700 figure is for a 128GB model, and a 128GB 6S Plus is a Grand dude. Look at the lower storage models, they are still cheaper than a iphone by 25% (even beats your toyota/hyundai comparison) Reply

    I mostly agree about your pricing point, a Huawei can't be so pricey , but your cars analogy is very poor: Hyundai and especially Toyota / Lexus (Japanese cars !) are making very good cars, even better than American's... Reply

    Mentioned this before, the SoCs memory score in Geekbench is all over the place, you haven't noticed anything off there?
    Other than that the SoC does ok , a bit of a pity that they don't use better NAND and WIFI since it would make a rather big difference in actual usage. Power is not ideal since it does throttle and you could have pushed further and load all 8 cores. The product should work at advertised speeds , anything less should be clearly disclosed to the consumer but considering how bad things are elsewhere , this is great.

    The phone is a bit pricey, the screen is just 1080p and not quite ok colors. Too bad since it's one of the most compact designs and almost nobody is doing that now, except maybe LeTV.

    Any clue on die size? Hope we see the SoC in better offerings, assuming it's not too big (and costly).

    "the screen is just 1080p"

    shhhhh, just shhhhhhhh

    I wouldn't complain about that if it was 200$ but it's not. There is a reason 1080p screens are in 120$ phones (even rather good displays like the one in the Meizu m2 Note). And it is 6 inch so you get about 367ppi vs 577 ppi in something like the S7. Reply

    You also get amazing battery life.....

    You believe that they need to add a "premium" screen to justify the asking price, when the "cheaper" parts are in fact better for the experience. I'd rather have them spend the savings on other components, like better flash, audio amplifiers with a better DAC, and a general better internal layout of components for easier repairability.

    If all parts are optimum and they still save a good buck on their BoM, then good for them.

    They're selling them to presbyopic middle-aged men on the verge of retirement who only need the phones to make calls, they can't see so clearly close-up in the first place so they need huge screens and not a lot of DPI. Don't count on a better DAC, it doesn't fit their positioning, especially in China, their main market. Reply
