Although the main focus of Huawei’s software team has been on the development of the Hongmeng ecosystem, the results of its past experience with Android optimization are still radiating, though, and even Android 13 is going to be used.
Esper reports that Google plans to make EROFS the default file system for Android 13 system partitions.
EROFS, known as Enhanced Read-Only File System, was developed by Huawei and is known as Super File System, and has been loaded on a large number of Huawei models since EMUI 9.
Its main advantages are faster application startup and random read performance increase by 20% on average, up to 300%. It also has the advantage of saving space, avoiding lag in low memory situations, etc.
Starting from Linux 5.4, EROFS file system is also officially included in the kernel.
Regarding this native Android support for EROFS file system, it is expected to affect only those devices that ship with Android 13 pre-installed and integrated with the full Google GMS suite, and will not take effect for AOSP.
