EMUI 9.1 Upgrade for Huawei Mate 20 Series

The new EMUI 9.1 will be available for Huawei Mate 20, Mate 20 Pro, Mate 20 X, and Porsche Design Mate 20 RS. Users of these four flagship models can sign up for the upgrade.

EMUI 9.1 features EROFS, a new super file system with improved file compression and 20% higher random read performance. EMUI 9.1 also upgrades GPU Turbo into version 3.0, supporting 25 games. It improves performance further while reducing device power consumption, bringing you a more stable gaming experience and a high frame rate. The upgrade also brings "moon mode" to the Mate 20 Pro and Mate 20 X, helping you take better moon photos through the super zoom capability of Leica triple cameras. The new "incoming call video show" feature replaces the traditional monotonous system ring tone and interface. Users can set different self-made or third-party videos as the incoming call displays for different contacts.

EMUI 9.1 Core Information
EMUI 9.1: Enjoy a higher quality of life

With the convergence of digital life and real life, smartphones and phone operating systems need to provide consumers with an efficient, balanced, and personalized experience. EMUI 9.1 features redesigned themes and icons, improved performance, as well as cutting-edge technologies, bringing you a colorful all-scenario AI experience and a higher quality of life.

Cross-generation cutting-edge technology
1.New EROFS file system

Huawei has been constantly innovating in operating systems, optimizing Android from the bottom layer up to improve performance. Back in 2016, Huawei pioneered the F2FS file system to replace the EXT4 file system in EMUI 5.1, which was released simultaneously with the Huawei Mate 9. This new file system improved response speed by 20%. The traditional EXT4 file system used by the Linux kernel is suitable for old mechanical hard disks, while the F2FS file system is customized for flash memory. This means that even after over a long time, the read and write performance of the flash memory stays strong.

F2FS only changed the user partition (equivalent to the D disk of the computer) of the Android system. In EMUI 9.1, Huawei innovates in the file system again, becoming the first to use EROFS in the system partition (equivalent to the C disk of the computer). This change brings the following improvements in mobile phone performance:

The random read performance is 20% higher on average, and the maximum random read performance is 300% higher.
Application launch speed is faster – over 10% faster in heavy-load scenarios.
Extra space saving: The system ROM takes up 2 GB less space.
There is no longer a frame freezing problem caused by repeated data reading and decompression when the memory is insufficient.
More secure: The EROFS is designed as read-only. The system partition cannot be rewritten by the third party, so it is more secure.

2.GPU Turbo 3.0 brings an amazing gaming experience

The P30 series is the first to support GPU Turbo 3.0, which optimizes gaming experience in an in-depth manner and supports 25 popular games, meeting the requirements of the vast majority of players. It supports almost-full-frame running for mainstream games. In addition, AI image scheduling smoothens jagged edges in images, improves clarity in dark environments, enriches image details, and further improves visual experience for players.
