I've put 5.0/5.1 on several devices, including a S2, S4, Mega 6.3 and Note 3 and couldn't disagree more.Could never go back to 4.4.Well a bit of a bump on this, i had 5.0 on this for 6 months and never got used to it or liked it, felt like a step backwards on many fronts.
Going back to 4.4.2
And when i get the Note 4 i'll be staying with KitKat too. Seems like the golden age of Android phone is over, how sad it ended like this..
