Huawei Mate 20 Pro's Overview Screen Is Buggy On EMUI, Other Launchers

It seems like Huawei’s overview screen needs some work, at least on the Huawei Mate 20 Pro. The Huawei Mate 20 Pro is the company’s current flagship, and based on my colleague’s experience with it, it’s not performing as it should. Nick Sutrich has been putting the Mate 20 Pro through its paces for some time now, as part of the review process, and has noticed that the overview takes a while to appear when using a gesture to call upon it (swiping up and holding). This gesture is much quicker on a number of other phones which use gesture navigation, so there’s really no reason for it to be different on the Mate 20 Pro / EMUI, as this seems to be more of a software problem than the Mate 20 Pro’s issue.

Now, if you switch to a third-party launcher, things are considerably different, but even worse than you can imagine, as is shown in the video down below. Overview is much faster to appear when using a third-party launcher (like Nova Launcher, in the given example), but as you can see in the video, it’s quite buggy, sometimes it decides to disappear on its own, and it actually seems like the system is trying to suppress it for some reason. Cards are behaving completely different when using a third-party launcher as well, animations are missing, while those cards will sometimes snap to the middle of the display, while other times they’ll simply scroll freely with no friction. On top of that, you can no longer fast-switch to an app by pressing the thumbnail if it’s not exactly in the center of the screen. In the given example (video), when we tried to quickly scroll through the carousel and tap a few apps to switch to them, the system threw us back to the home screen instead of opening the desired app. Interestingly enough, this cards navigation problem appears even if you’re using on-screen buttons instead of navigation gestures.

Speaking of on-screen buttons, if you enable them, you’ll face another problem. If you double-tap the Overview square button in order to quickly switch between the last two apps you’ve used, the system will often show you the animation for app-switching, but it will not navigate you to the desired app. Instead, it will just go to the foreground application most of the time. The quicker you perform the action, the worse this problem gets, and it actually occurs in both stock and third-party launchers, though truth be said, this is an Android 9 Pie problem, as we’ve seen other phones having this very same issue with fast app switching using the Overview button. You can check out all of these issues in the video that is embedded down below.

Background: The Huawei Mate 20 Pro was announced alongside the Huawei Mate 20 and Mate 20 X last month. The Huawei Mate 20 Pro is regarded to be the most powerful Huawei-branded devices to date, and in our testing thus far, it’s a really, really good phone, but this overview issue needed to be mentioned. The Huawei Mate 20 Pro is made out of metal and glass, while the phone includes three cameras on the back. The device features a 6.39-inch QHD+ AMOLED display, while it sports 6GB / 8GB of RAM and 128GB / 256GB of storage. The phone is fueled by the Kirin 980 64-bit octa-core processor, while it comes with a 4,200mAh battery which can utilize 40W fast battery charging (70-percent in 30 minutes). The device also supports Qi wireless charging, 15W fast charging, to be exact. 40, 20, and 8-megapixel cameras are included on the back of the Mate 20 Pro, while the device comes with Leica’s lenses. Android 9 Pie comes out of the box on the device, with Huawei’s Emotion UI (EMUI) 9 pre-installed. The phone is also IP68 certified for water and dust resistance, while it weighs 189 grams. On top of everything, the Mate 20 Pro includes stereo speakers, and has an in-display fingerprint scanner, as well as facial scanning. A 24-megapixel camera sits on the phone’s front side, and the device is 8.6mm thick, while it weighs 189 grams. The phone is 157.8mm tall, and it’s 72.3mm wide.

Impact: Having said that, this Overview screen issue is probably happening on other Mate 20 phones, though we cannot confirm that at this point. Huawei’s Emotion UI (EMUI) skin never actually played nice with third-party replacements of system-level applications, though there were ways to amend those problems. Well, the issues that we’ve talked about in this article are connected to the company’s skin, but also to Android 9 Pie, as the last issue we talked about happens on other Android 9 Pie-powered phones as well. In any case, Huawei is probably aware of this by now, or it will be soon, but the company will probably fix this in an upcoming update. Using Overview on the Mate 20 Pro can be quite frustrating, no matter if you’re using a stock launcher or a third-party launcher, even though things get immensely worse if you’re using a third-party launcher. The company needs to clear up some Overview-related bugs, and make it work fine with both its very own launcher, and third-party ones, as that’s the way it’s intended to work. Having said that, Huawei’s Emotion UI (EMUI) skin is much better than it was before, we won’t get into much detail here, but we’re in the process of testing it as part of our Mate 20 Pro review. It was quite good on the Mate 20 and Mate 20 Pro we’ve tested earlier this year, and the company is taking steps to improve it further, though issues such as this one with the Overview screen should not happen, that’s for sure. The good thing is, this should be a relatively easy fix for Huawei, it’s obviously a software glitch, and nothing that a firmware update can’t fix, though it remains to be seen how long will it take for Huawei to patch things up and make Overview functional again, the company will hopefully do that in the near future.
