Android 13 will have an interesting novelty created and developed by HUAWEI

Google recently announced their new version of Android, Android 13, which will feature many improvements, some of which are very interesting and which they commented on at the recent Google I/O. but there are others that are not mentioned.

And that’s what, for Android 13, Google plans to include a new, greatly improved read-only file system that it’s called EROFS, and curiously, it’s created and designed by HUAWEI..

This file system offers a fairly large number of advantages over systems in use todayand especially when compared to f2fs or ext4, the default systems in Android smartphones today.

EROFS is a system provides better performance in terms of reading and writing files applies, in addition to having the main characteristic of having such effective compression which allows these files to be significantly smaller than, say, f2fs.

The use of this file system is interesting because will only be used for device partitions that are read-onlyas is the case with the system partition, which only changes when a system update is performed, who is usually very punctual.

This system is developed in open source, and in addition, integrates into the Linux kernel itselfwhich makes its inclusion almost native to any of the systems that want to include it.

EROFS is already integrated into Linux kernel version 5.4, so it’s available to other companies, and here’s an interesting detail, HUAWEI is not the only company using it..

As the EMUI team already announced three years ago, EROFS allows you to increase the write speed by 20%getting with the same increase the size of these files by almost 40%.

With the Expandable Read-Only File System (EROFS), we’ve increased random read speed by 20% and freed up more space on your phone to store your favorite photos and songs. #RewriteRules With #EMUI 9.1.#HUAWEI #HUAWEIIP30 #HUAWEIIP30Pro pic.twitter.com/1ATpd0qXHf

And these are companies like OPPO, OnePlus and Xiaomi. And that’s what for two years now, all OnePlus and OPPO have been especially using this technologyand provided them with incredible performance when opening applications and significant savings on read-only system partitions.

For example, the system folder usually has an approximate size between Size 1.8 and 2.4 GB, which includes Android apps and files, as well as files from each company. with EROFS this size is between 1.3 and 1.5 GBsignificantly reducing its size thanks to superior compression without sacrificing performance.

This EROFS system will be enabled on all smartphones with Android 13 and Google services, and this will be good news for users, as we will get performance and a few extra megabytes of memory.
