    Arrow OS

    Arrow OS

    It is an AOSP based project with an aim of keeping things clean!

    ArrowOS is an AOSP based open source project started with the aim of keeping things simple, clean and neat, both for the Android system and users. We understand the pain of unnecessary and sometimes rarely used mods/features being shipped with custom roms nowadays which may end up causing battery drains and/or memory leaks. This is being strictly avoided on our side keeping everything to a bare minimum, delivering the stable performance all the time without destroying the AOSP interface. With users getting more used to tweaks and features, we added just the right stuff that will be actually USEFUL at the end of the day.
