I’m writing this review about note 4( 3gb) after using 5 days. It has some Metallic and plastic top finishing. It’s battery is better than mi note 3. After update the phone ram optimization increased nearly 2gb ram free out of 3gb. Camera also better than note 3 but not good than zuk z1, g4 plus, mi 4i, v3 etc. Phone never got hanged while playing heavy games. Sound quality and mic also have good quality. No heating issue while call, playing games, watching videos, internet etc. Finger print also works well. Fast charging is missing in it, its the disadvantage in it. This is good choice if your primary need not camera.
