Although Huawei's software team has focused on the development of Hongmeng ecology, its experience and achievements in Android optimization in the past still shine, and even Android 13 will be used. Esper reported that Google plans to use erofs as the default file system for Android 13 system partition.
The full name of erofs is enhanced read only file system (extensible read only file system), which is developed by Huawei and called super file system. Starting from emui 9, a large number of Huawei models are loaded.
*Its main advantage is that the application startup speed is faster, and the random reading performance is improved by 20% on average and up to 300% at most. Moreover, it also has the advantage of saving space and avoiding Caton and other * in the case of low memory.
Since Linux 5.4, the erofs file system has also been officially incorporated into the kernel.
With regard to the native Android support for the erofs file system, it is expected that it will only affect those devices pre installed with Android 13 and integrated with the complete Google GMS suite, which will not take effect for AOSP.
