It's a good phone as compared the price. Lollipop is much better. No need to revert back to kit kat. The lagging lockscreen is nothing for now since the permanent fix released. Just download'wake lock power manager' from google playstore and activate the'partial_ wake_ lock'. Be sure to enable the notification because the system may kill the app processes. But before that go to settings then developer options on your device and untick the'awsome media player'. I'm sure you'll be happy with this lollipop firmware update.
Features
Let’s start with the display. The Note 3 Neo gets a HD AMOLED( 1280 x 720) panel which is exactly what the Note II had. However, the quality of the Neo’s panel is quite inferior to Samsung’s earlier Note flagship.
