Samsung Galaxy S5, Samsung Galaxy S4 both receive unofficial AOSP-based Android 5.0 Lollipop builds!
We've already seen Samsung's take on Lollipop for the Galaxy S5 and the Galaxy S4 in a couple of exclusive previews, but we'll have to wait for these a little longer. Meanwhile, the Google Play Edition of the Galaxy S4 will most probably be among the first Samsung devices to receive a fully working Android 5.0 build.
These early unofficial firmwares for both devices are based both on AOSP and an alpha CyanogenMod 12 build, mind you. Naturally, these come with a hefty amount of bugs and a number of fundamental features are not working at the time of writing. This exact Android 5.0 Lollipop build for the Galaxy S5 is a tad more stable, as only the camera and NFC are not working; in the meantime, the older S4 warrior is currently suffering from non-functional external storage, GPS, IR blaster, NFC, RIL, and sound - it goes without saying that these flaws deem the builds non-compliant for daily drivers (at the moment, that is).
