Huawei June 2022 update fixes EMUI 12 feature issue
Huawei has recently published June 2022 EMUI security patch details. June 2022 bulletin mentioned a bunch of EMUI security flaws that have been fixed but there’s one specific Huawei EMUI 12 feature issue that we want to mention here.
Huawei EMUI June 2022 security patch fixes EMUI 12 multi-device task center feature issue, the exploitation of this feature could allow attacks to compromise your device’s data. However, it’s fixed with the upcoming firmware version and patched with June 2022 security patch.
Multi-Task Center:
This feature is powered by Huawei’s cross-device capabilities used in EMUI devices that allow you to get the most out of the software. Based on the concept of multi-device collaboration, the feature allows you to project application data from one device to another in real-time, check the example below.
For instance, if you are running a game on your smartphone, you just need to go to the task manager of the phone and task manager view. Now, tap on the device (such as a tablet) to run the corresponding app. However, the user must first need to connect the tablet and the phone via the same WiFi network and Huawei ID.
Similarly, another task can also be handled by the task center such as viewing documents on a tablet for a bigger view, without even installing any additional app.
Check all of the issues that are mentioned in the June 2022 EMUI security patch.

Huawei has released the January 2023 software update for the Huawei Nova Y90 and Y70 smartphones in the global market, and this firmware clearly improves these phones’ security aspects for a better user experience.
Both Huawei Nova Y90 and Y70 runs EMUI 12 out of the box but it would be interesting if the company could have sent EMUI 13 instead of the security patch. Speaking of which, no one knows, when Huawei will rollout EMUI 13 for global users for the time being.
Coming back to the rollout, January 2023 security update for Huawei Nova Y90 and Nova Y70 comes with EMUI version 12.0.1.177 and EMUI 12.0.1.202. This update is suggested to install on all of the devices sold marketed outside of China and will appear in batches.
We suggest the corresponding users look into the settings > then open System & updates, followed by a Software update, and then tap on CHECK FOR UPDATES. You can download the latest firmware also from the My Huawei app.
You should know that the update won’t erase your personal data but it is suggested for you back up any important data before updating the device. On the other hand, the package will be deleted automatically once the installation succeeds.
