Mate RS Porsche EMUI 12 update security patch April 2022

And the next model gets the EMUI 12 update. This time it’s Mate RS Porsche Design’s turn. It is very gratifying that older flagships and Lite models now also receive the EMUI 12 update. Due to the embargo, the foundation is still Android 10, which has pros and cons. The downside, of course, is that there is no new Android version. On the other hand, Huawei is now openly capable of delivering significantly more devices with EMUI 12 updates than was the case with previous EMUI updates. In any case, it’s a small consolation that there are almost no new Huawei smartphones to buy due to banned 5G technology and the lack of Google services.

Unfortunately, the update size cannot be seen on the screen, but the EMUI 12 update size varied between on other devices 1.96 GB and 4.57 GB. In any case, it is not a small amount of data, if you do not have a very generous amount of data or prefer to use your data elsewhere, I would advise you to use a WLAN for download.

Additionally, before starting the EMUI 12 update, you should calm down your impatience and anticipation for a moment and MUST make a backup, at least from your main apps. You can find the function in Settings under System → Backup & Restore. After major updates, there is always one or the other problem and you may need to reinstall an app or even reset your smartphone to factory settings. If you do not have a backup, you often get in big trouble.

Changelog EMUI 12 update

list of changes
This update introduces EMUI 12, which provides an intuitive interface and a cross-device panel on the control panel for better smart collaboration.

Innovative interactions

Supports more flexible font customization, where you can adjust the font size and width with a slider.

[Neuromorphes Design]
Applies the concept of neuromorphism to UI elements. It uses simple colors, tones, shadows and highlights to achieve a more realistic effect.

[Intelligente Ordner]
Supports tapping and holding app folders on the home screen to make them larger and easier to access apps inside.

[Benachrichtigungsfeld und Steuerfeld]
Allows you to swipe down from the top left of the screen to access the notifications panel to view messages, and swipe down from the top right of the screen to access the control panel to use shortcuts. Adds a sound control panel to the panel to make it easier to switch between different audio devices and apps.

Allows you to easily multitask in split screen mode and send messages in a floating window while watching videos or games. Swipe in from the left or right edge of the screen and hold down the screen to display the multi-window dock. Tap and hold an app icon in the Dock and drag it to the side of the screen to split the screen. Alternatively, you can tap an app icon to view it in a floating window. You can later minimize the floating window to a floating bubble for easier access.

Smart Life in all scenarios

[Smart Office]
Supports accessing documents or pictures on the phone from a laptop without connecting the two devices with a data cable.
Improves Huawei Share transfer speeds for faster file sharing between Huawei phones, tablets and laptops.

Adds the MeeTime app that lets you make HD voice and video calls over WiFi or a data network.
Adds screen sharing support during video calls so you can tag and share key information in video chat.
Note: MeeTime is only available in certain countries and regions:

Allows you to scan documents. You can now quickly identify and extract text from images, edit the text, export to multiple file formats and share.

On the Discover tab in the gallery, you can create video stories using pre-installed templates, special effects, and background music.
The video editing features have been streamlined and provide further instructions on how to use the timeline and
Editing options available.

[Störungsfreie Bildschirmprojektion]
When you project your phone to your Huawei laptop in Do Not Disturb mode, messages and incoming calls only appear on the phone screen. This protects your data and avoids screen projection interruptions.

Update notes

  1. This update does not delete your personal information. However, it is recommended to back up important data before updating.
  2. Some third-party apps that are not compatible with EMUI 12 may not work properly after updating. It is recommended to update these apps to the latest version in the App Store
  3. If you encounter problems during the update, call the HUAWEI Customer Hotline or visit a HUAWEI Customer Service Center.
  4. The layout of the home screen may change slightly.
  5. The system version can be rolled back to the official version EMUI 11 in HiSuite. Rolling back the system version will erase all your personal data. Therefore, back up your data in advance.
  6. The update package is automatically deleted when the update is complete.
  7. See Tips for more features.

Did you already get the update, did you get an update for another device? Yes!? So please send us screenshots, either via email or in our Facebook community.

Make sure all the details of the change log are visible. To do this, simply use the small arrow on the right edge to display the entire text. If there is a lot of text, there may also be more pictures.

You can still take the screenshot after installing the update. To do this, simply download the system update again and tap on the current version. Thank you very much! <3
