h2. Status
4 46 Denis 'GNUtoo' Carikli
5 49 Denis 'GNUtoo' Carikli
* The Galaxy SIII 4G (i9305) boots (with graphics hacks) under AOSP9, without having to import nonfree libraries. Not much has been validated beside that.
6
* The kernel used is based on Linux 5.0-rc6 and has ~150 Android specific patches on top and some patches for the Galaxy SIII 4G (i9305) on top
