As the Titel says, EMUI 9.1 is coming for MediaPad M5 and for more 49 Devices from Huawei and its sub-brand Honor.

The confirmation is from the Chinese club.huawei (see the attachment below)

Why EMUI 9.1 is a really big deal and better than its previous firmware:

PERFORMANCE

Previously, the F2FS file system was tailored for flash memory to improve the read and write performance after long-term use. Now, with EROFS, the random read speed will be 20% faster and the system space will provide extra personal storage of up to 1000 pictures or 500 songs. Plus, the read-only memory design isolates outside interference for added security in your system files.

GPU TURBO 3.0

GPU Turbo 3.0 is a new upgrade that covers 25 of the most popular games. This new update includes reducing SoC power consumption by 10% and optimizing the underlying system performance to provide a continuous gaming experience.

HUAWEI VLOG

It has new features and effects that are perfect tools for easy editing and you can share with one-click. The Highlight videos are automatically edited with dramatic filters and give you the option to apply special speed effects and unique background music. Your cherished videos can be transformed into a personal cinematic masterpiece.

ANYTIME ASSISTANT

Whenever you need to use the virtual assistant to carry out tasks, look up facts or need an answer to a simple question, just press and hold the power button and the Google Assistant will launch in a second.

AR MEASURE

When you need a quick measurement tool for simple DIY projects, just open the AR Measure App. You can accurately measure length, total area and volume with the Huawei TOF Camera.

By utilizing the Face Recognition technology, you can now measure the height of a person with just a simple task of scanning from toe-to-head.

ONEHOP

A simple tap from your phone to the computer can send pictures, videos, and documents in seconds. You can also efficiently copy and paste between devices with Huawei Share OneHop.

And, while playing a game, just shake and touch the phone to your computer to initiate a 60-second recording of the screen1 that saves to your phone.

HUAWEI CARKEY, SECURE AND CONVENIENT

EMUI 9.1 allows you to automatically unlock your car with NFC on your phone when you forget the key and you can share this key with up to 5 people.

You can still unlock your car even if your phone is out of battery. Additionally, you can start your engine using your phone, once the phone is placed inside the secure phone box.

THE PERFECT WORKOUT PARTNER

EMUI 9.1 turns your phone into an ultimate workout partner. Use your phone to connect to a treadmill and collect information like calories burned, running speed and length of the workout.

The phone can also use an algorithm to intelligently measure the step vibrations, so you can accomplish your personal fitness goals.
