Smartphones with native Android 13 will have Huawei’s EROFS file system
In recent months we have learned to discover all the Announcements (so far) come up Android 13, for safety, games and much more. But there is one that has not attracted much attention, and that is the introduction of Huawei’s EROFS Linux file system format, announced four years ago.
The new file system (here you can find more information) will be a requirement for smartphones that will be placed on the market with Android 13 and allows you to overcome the EXT4 format (which does not support compression) currently used by most manufacturers.
But what will the new file system allow for? EROFS (Extendable Read-Only File System) is, as the name implies, meant for partitions in read only and allows higher speeds as well as reduce memory overhead. In addition, thanks to compression, it reduces the space that these partitions may have to occupy, allowing them to have smaller OTA update images.
But that’s not all. According to the creators of the file system, EROFS also allows you to reduce the “application startup time of the real world up to 22.9%almost halving the use of storage space “, also allowing to beat the EXT4 and F2Fs standards in uncompressed applications (here are some graphics). As mentioned at the beginning, the new file system will be a requirement for new devices with Android 13 (Pixel 7 above all, but OPPO and Xiaomi are already using it), while the partitions of the User data on most phones they will presumably continue to be EXT4 or F2FS.
