So i've been on my Nexus 4 for the past year and my brother took my SGS,
I'm currently on Jelly Bean and want to know if the upgrade to KitKat has the performance improvements that was claimed with the release.
You know, easier to run on lower mem devices and such.
Also, what must I look out for?
Do I need a special kernel to upgrade before, or update my recovery to some different version, or is there a higher risk of bricking/losing my efs than the usual download/flash? Can I easily downgrade to JB/ICS?
