The EMUI 9.1 comes with many useful features. Let’s talk about them – Here are all the features coming with EMUI 9.1 update to Huawei P20 series:

  • Advantages of EROFS

The EROFS file system is equivalent to optimizing the partition of the Android system. The EXT4 file format of the system partition (equivalent to the C disk of the computer) is replaced by the EROFS (Extendable Read-Only File System) independently developed by Huawei. This is equivalent to a major operation on the Android system C drive.

In the EROFS file system, the random read performance of the mobile phone is increased by 20% on average, the application startup speed is faster, and the system ROM space is saved by 2 GB. In addition, it can avoid inefficient memory reading data repeatedly, decompressing the whole machine jam caused by data.


The EROFS design is a read-only design, system partitions will not be rewritten by third parties, security can be assured.

In fact, this is not the first time Huawei has applied to the bottom of the system. In the EMUI 5.0 era, Huawei adopted the F2FS file system for Android’s user partition (equivalent to the computer’s D drive), replacing the traditional EXT4 file system, in order to improve the read and write performance of the flash memory after long-term use and improve the file access fluency. 20%.

  • ARK Compiler

In addition to the EROFS file system, Huawei also launched its own Ark compiler to improve system fluency.

The Ark compiler provides a new system and application compilation and operation mechanism. From dynamic compilation to static compilation, it can directly compile high-level languages into machine code, eliminating the extra dynamic compilation of virtual machines. Overhead.

According to the test data of Huawei Lab, EMUI 9.1 applied the Huawei Ark compiler to the system component System Server, the system operation fluency increased by 24%, and the system response performance increased by 44%. The fluency of third-party applications after recompilation is expected to increase by 60%.


However, to achieve such an improvement, developers need to use the Ark compiler for development. At present, the Huawei Ark compiler has been open sourced to the industry.

  • Redesigned the system UI

In addition to system-level improvements, EMUI 9.1 redesigned the system UI. This version focuses more on natural minimalism and streamlines and merges many complex options.

For example, wallpapers, themes, and icons use a micro-realistic style to further beautify, while the number of default horizontal icons has been reduced from five to four.

With the increase in experience, some complex options for system splitting are no longer necessary. EMUI 9.1 is based on merging and deleting processing.


For example, the alarm setting interface, the silent mode alarm is turned on by default, so that the date and time are not repeated. Other operations such as desktop settings, weather settings, time switch, cell phone housekeeper, and do not disturb have been handled similarly.

In addition, EMUI 9.1 reduces unnecessary interruptions to users. Before the version of EMUI 9.1, the screen will count down before the screen is recorded, which makes it impossible to capture the picture accurately. EMUI 9.1 does not have a pop-up window to directly record the screen, giving users a better experience.

  • 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. It now supports AI image adjustment to make visual enjoyment even further.
