Google will launch the ultimate model of Android 13 later this fall. The corporate began testing Android 13 again in February 2022, and it formally showcased it, revealing the a number of options and enhancements it’s going to include, earlier this month at Google I/O.
As a result of time constraints and numerous different causes, Google was, naturally, unable to deep dive into each function that the Android 13 will include. Android specialist Mishaal Rahman has now found one other hidden function of Android 13, the EROFS file system, that Google is reportedly planning to implement with the upcoming Android replace. Here is every little thing that that you must find out about it.
What’s the EROFS file system?

Earlier than we get to EROFS, you need to find out about what a file system is. A file system is principally the tactic and knowledge construction an working system makes use of to manage how knowledge is saved and retrieved. Consider it as a kind of index for all the information saved in a tool. With no file system, it will be troublesome for an OS to determine and retrieve recordsdata from the storage.
Each OS makes use of a unique kind of file system: Microsoft’s Home windows makes use of the NTFS file system, and Apple’s macOS makes use of its personal APFS file system. File techniques resembling FAT32 and EXT are a few of the previous file techniques which can be supported by most gadgets. Android gadgets additionally use various kinds of file techniques — whereas a lot of the gadgets offered at the moment use the united statesfile system, most Android smartphones assist the EXT4 file format because the working system relies on Linux.
From HUAWEI to Linux to Android: Story of the EROFS File System
EROFS stands for Enhanced Learn-Solely File System. EROFS is not actually a ground-breaking new expertise that Google has developed. As a substitute, it was created by the HUAWEI engineer Xiang Gao again in 2018 and has been in use in the HUAWEI telephones for the previous couple of years. EROFS, because the title suggests, is a read-only file system that Google is now planning to carry to all Android gadgets. Since it’s a read-only file format, it is going to be used in just some elements of the OS. Nonetheless, it affords an a variety of benefits over the present implementation, about which we are going to discuss at a later stage.
Enjoyable Reality: Typically, EROFS can also be known as the Extendable Learn-Solely File System.
When Xiang launched the EROFS file system, he stated that the brand new read-only format “focuses extra on efficiency than purely on saving space for storing as a lot as doable.” As a proof of idea, he posted knowledge evaluating the sequential and random learn/write speeds of a HUAWEI cellphone with an EROFS partition vs. the identical cellphone that was utilizing the EXT4-formatted partition. The outcomes, as you may see down beneath, are promising.

After a yr of growth, HUAWEI formally launched the EROFS file system into its Android smartphone with EMUI 9.0.1, however it solely turned broadly out there with EMUI 9.1. Because of the enhancements it affords, EROFS was built-in into the Linux working system with model 5.4. It was adopted by HONOR as nicely. And now, due to Google making it obligatory for Android OEMs, different corporations like OPPO, Samsung, OnePlus, and Xiaomi will assist EROFS.
What are the benefits?
Speaking about some great benefits of the EROFS file system, it affords higher efficiency and higher data-saving methods than the present options. Whereas compressing knowledge usually results in dangerous efficiency, HUAWEI has developed an answer that provides one of the best of each worlds. Learn speeds are about 25% quicker than that of an EXT4 file system. When a system is flashed on an Android gadget with EROFS and an Android gadget with out one, the EROFS Android gadget affords as much as 2GB of more room, making it nice for gadgets with restricted storage capabilities. Furthermore, since it is a read-only system, it affords higher safety in phrases of defending system recordsdata.

In a analysis paper that Xiang filed, he says that the “EROFS outperforms present compressed read-only file techniques with numerous micro-benchmarks and reduces the boot time of real-world purposes by as much as 22.9% whereas practically halving the storage utilization.” In easy phrases, EROFS claims a serious enhance in efficiency all whereas lowering the space for storing used. The way it will carry out in the actual world stays to be seen, but when the current HUAWEI telephones have instructed something, it is going to be quick.
Not all Android 13 gadgets will profit from the EROFS file system
The introduction of the brand new file system would not essentially imply that every one the Android 13 gadgets will use the brand new EROFS file system. The change will solely be obligatory for the gadgets that launch with Android 13 pre-installed. Telephone producers can implement the brand new file system on their smartphones after they replace their gadgets to Android 13, however it’s not obligatory.
In accordance with Mishaal Rahman, the upcoming Google Pixel 7 (and seven Professional) shall be one of many first smartphones to come back with an EROFS file system partition. Equally, you may anticipate smartphones from OnePlus, Samsung, Motorola, and others to change to this file system when Android 13 turns into official.
And, oh, the EROFS file system will most likely be solely used for the read-only system partition. In accordance with the figures reported, this may considerably enhance the system’s efficiency. However, the consumer knowledge read-and-write partition will nonetheless use the nice previous EXT4 or F2FS file partition — except Google has some plans for this as nicely. However, by default, gadgets operating on AOSP (Android Open Venture) or AOSP-based ROMs won’t use EROFS.
EROFS looks as if a promising Android 13 function. Regardless that it is probably not making headlines like the opposite greatest new Android 13 options, resembling improved colour theming and enhanced privateness and safety, it is among the options that might influence system efficiency and enhance the longevity of the Android 13 gadgets. What are your ideas on Google implementing EROFS in Android 13? Do you check out the file system of the gadgets earlier than shopping for? Tell us in the feedback part beneath!
