The Galaxy Note 4 still not have the Lollipop 5.0 but Samsung saying the would jump to the 5.0.1 but when? And when do the Lollipop 5.1 will be available for the Note 4? Probably the will get it in June.
Very bad update time line for Samsung while the last year Motorola phone Motorola Moto X 2013 and Moto G 2013 are running on Lollipop the latest from Samsung Note 4 and Note Edge still behind and even though the Galaxy S5 are starting to receive it, Motorola have 4 devices that got android Lollipop. The Moto X 2014 and 2013, the Moto G 2014 and 2013. Now waiting for the Most affordable value phone the Moto E to receive the update. Well done Motorola.
Only got 5.0.1 this morning on my n5, haven't had the bugs some have been reporting though, lucky for me.
